Description

[Technical Field]

[0001] The present specification relates to a display device. [Background technology]

[0002] Recently, with the advent of the information age, the field of displays, which visually represent electrical information signals, has been developing rapidly. As a result, various display apparatuses with excellent performance in terms of thinness, light weight, and low power consumption have been developed.

[0003] For example, display devices can be classified into liquid crystal display devices, field emission display devices, organic light emitting display devices, and the like.

[0004] Among these display devices, a liquid crystal display (LCD) is a device that includes an array substrate including thin film transistors, an upper substrate including a color filter and / or a black matrix, and a liquid crystal layer between the array substrate and the upper substrate. The alignment state of the liquid crystal layer is controlled by an electric field applied between two electrodes in the pixel area, and the light transmittance is controlled according to the alignment state, thereby displaying an image.

[0005] In addition, the organic light emitting display device is a self-emitting element and has advantages such as low power consumption, fast response speed, luminous efficiency, brightness, and a wide viewing angle. Summary of the Invention [Problem to be solved by the invention]

[0006] A display device generally requires a separate speaker to display an image on a display panel and provide sound. When a speaker is installed in a display device, the sound generated from the speaker travels not in front of the display panel where the image is displayed, but toward the rear or bottom of the display panel, for example, and does not travel toward the viewer viewing the image displayed on the display panel, which disrupts the viewer's immersion.

[0007] In addition, the sound generated from the speaker travels to the rear or bottom of the display panel, resulting in a deterioration in sound quality due to interference with the sound reflected from the walls and floor.

[0008] Furthermore, when speakers are included in a set of equipment such as a TV, laptop computer, or computer monitor, the speakers take up space, which creates a problem of constraints on the design and spatial arrangement of the set of equipment.

[0009] Therefore, the inventors of the present specification recognized the above-mentioned problems and conducted several experiments to determine whether the sound quality can be improved by making the sound travel in the direction of the front of the display panel when watching an image from the front of the display panel. Through these experiments, they invented a display device with a new structure that can generate sound so that the sound travels in the direction of the front of the display panel, thereby improving the sound quality.

[0010] An object of the embodiments of the present specification is to provide a display device including a sound generating device that can generate sound so that the sound travels in the front direction of the display panel.

[0011] An object of the embodiments of the present specification is to provide a display device including a sound generating device with a new structure that can realize stereophonic sound.

[0012] The problems associated with the examples of the present specification are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. [Means for solving the problem]

[0013] A display device according to an embodiment of the present specification includes a display panel that displays an image and includes a first region, a second region, a third region, a fourth region, and a fifth region. The display device includes at least one first sound generating device and at least one fourth sound generating device that are arranged in the first and fourth regions in a left region on the rear surface of the display panel. The display device includes at least one second sound generating device and at least one fifth sound generating device that are arranged in the second and fifth regions in a right region on the rear surface of the display panel. The display device includes at least one third sound generating device that is arranged in the central region on the rear surface of the display panel in the third region. The at least one first sound generating device, the at least one second sound generating device, and the at least one third sound generating device vibrate the display panel to generate sound, and the at least one fourth sound generating device and the at least one fifth sound generating device vibrate the display panel to generate sound above or upward from the display panel.

[0014] A display device according to an embodiment of the present specification includes a display panel that displays an image and includes a first region, a second region, a third region, a fourth region, and a fifth region. The display device includes at least one first sound generating device and at least one fourth sound generating device disposed in the first and fourth regions in a left region on the rear surface of the display panel. The display device includes at least one second sound generating device and at least one fifth sound generating device disposed in the second and fifth regions in a right region on the rear surface of the display panel.

The display device also includes a first partition that separates sounds from the at least one first sound generating device, the at least one second sound generating device, and the at least one third sound generating device from the at least one fourth sound generating device and the at least one fifth sound generating device.

[0015] Further details of the embodiments are included in the detailed description and drawings. [Effects of the Invention]

[0016] The display device according to the embodiment of the present specification is configured with a sound generating device that vibrates the display panel to generate sound, thereby generating sound so that the sound travels in the direction in front of the display panel, thereby improving the sense of immersion for viewers watching images on the display device.

[0017] The display device according to the embodiment of the present specification can be slimmed down by configuring the sound generating device within the display panel, and can realize a sound generating device that can improve sound.

[0018] The display device according to the embodiment of the present specification can realize a display device having stereophonic sound in the left and right and up and down directions by configuring a plurality of sound generating devices.

[0022] The advantages and features of the present invention, as well as methods for achieving them, will become clearer with reference to the following detailed description of the embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and may be realized in various different forms. The embodiments are provided solely to complete the disclosure of the present invention and to fully convey the scope of the invention to those skilled in the art to which the present invention pertains. The present invention is defined solely by the scope of the claims.

[0023] The shapes, sizes, ratios, angles, numbers, etc. disclosed in the drawings for illustrating the embodiments of this specification are illustrative only, and the specification is not limited to the details shown in the drawings. The same reference symbols refer to the same components throughout the specification. Furthermore, in describing this specification, if a detailed description of related prior art is deemed to unnecessarily obscure the gist of this specification, such a detailed description will be omitted. When terms such as "comprise," "have," and "consist of" are used in this specification, other parts may be added unless "only" is used. When a component is expressed in the singular, the plural is also included unless otherwise explicitly stated.

[0024] When interpreting elements, they are interpreted as including a margin of error even if there is no other explicit description.

[0025] When describing a positional relationship, for example, when describing the positional relationship of two parts by "above," "on top," "below," or "beside," one or more other parts may be located between the two parts unless "immediately" or "directly" is used.

[0026] When describing a temporal relationship, for example, when the temporal sequence is described using "after," "following," "next," or "before," it can also include cases where things are not consecutive, as long as "immediately" or "directly" is not used.

[0027] Although terms such as "first" and "second" are used to describe various components, these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, the first component described below may be the second component within the technical concept of this specification, and similarly, the second component may also be the first component.

[0028] In describing components in this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are used merely to distinguish the component from other components, and do not limit the nature, order, sequence, or number of the components. When a component is described as being "coupled," "coupled," or "connected" to another component, it should be understood that the component can be directly coupled or connected to the other component, but that there may also be other components "intervening" between components that can be indirectly coupled or connected unless otherwise explicitly stated.

[0029] "At least one" should be understood to include all combinations of one or more of the associated components. For example, the meaning of "at least one of the first, second, and third components" can include all combinations of two or more of the first, second, and third components, not just the first, second, or third component.

[0030] In this specification, the term "display device" may include display devices such as a liquid crystal module (LCM) including a display panel and a driver for driving the display panel, an organic light emitting display module (OLED module), etc. It may also include set electronic apparatus or set device or set apparatus such as a laptop computer, television, computer monitor, automotive apparatus or other form of vehicle, which is a complete product or final product including an LCM or OLED module, and mobile electronic apparatus such as a smartphone or electronic pad.

[0031] Therefore, the display device in this specification may include a display device itself such as an LCM or an OLED module, as well as an application product including an LCM or an OLED module or a set device for an end user.

[0032] In some cases, an LCM or OLED module consisting of a display panel and a driver may be referred to as a "display device," and a completed electronic device including the LCM or OLED module may be referred to as a "set device." For example, a display device may include a liquid crystal (LCD) or organic light emitting diode (OLED) display panel and a source PCB, which is a controller for driving the display panel. The set device may further include a set PCB, which is a set controller electrically connected to the source PCB and drives the entire set device.

[0033] The display panel used in the present embodiment may be any type of display panel, such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, or an electroluminescent display panel, and is not limited to the embodiments. For example, the display panel may be a display panel that can generate sound by vibrating with a sound generating device according to the embodiments of the present specification. The display panel applied to the display device according to the embodiments of the present specification is not limited to the shape or size of the display panel.

[0034] For example, if the display panel is a liquid crystal display panel, it may include a number of gate lines, data lines, and pixels formed at the intersections of the gate lines and the data lines, and may include an array substrate including thin film transistors as switching elements for adjusting light transmittance in each pixel, an upper substrate including a color filter and / or a black matrix, and a liquid crystal layer formed between the array substrate and the upper substrate.

[0035] If the display panel is an organic electroluminescent (OLED) display panel, it may include a plurality of gate lines, data lines, and pixels formed at the intersections of the gate lines and data lines. It may also include an array substrate including thin film transistors (TFTs) that selectively apply voltage to each pixel, an organic light emitting device (OLED) layer on the array substrate, and an encapsulation substrate or encapsulation substrate disposed on the array substrate to cover the organic light emitting device layer. The encapsulation substrate protects the TFTs and the organic light emitting device layer from external impacts and prevents moisture and oxygen from entering the organic light emitting device layer. Layers formed on the array substrate may include an inorganic light emitting layer, such as a nano-sized material layer and a quantum dot light emitting layer. Another example may include a micro light emitting diode (LED).

[0036] The display panel may further include a backing, such as a metal plate, attached to the display panel. It may also include other structures, for example, different structures made of other materials.

[0037] The features of the various embodiments of this specification may be partially or fully combined or combined with each other, and various technical interlocking and driving mechanisms may be possible. Each embodiment may be implemented independently of the other, or may be implemented together in a linked relationship.

[0038] The following detailed description of the present invention will be given with reference to the accompanying drawings and examples. The scales of the components shown in the drawings are different from the actual scales for the sake of convenience of explanation, and are not limited to the scales shown in the drawings.

[0039] 1A is a diagram showing a display device including a sound generating device according to an embodiment of the present specification, and shows the front of the display device.

[0040] 1A, a display device 10 may include a display panel 100 that displays an image and a sound generating device 200. The sound generating device 200 may vibrate the display panel 100 to generate sound (SW) in the front (FD) of the display panel 100. The sound generating device 200 may be disposed on the rear surface of the display panel 100. The rear surface of the display panel 100 may be expressed as one surface, a first surface, a rear surface, a bottom surface, or the like, and is not limited to these terms.

[0041] The display panel 100 displays an image, for example, an electronic image or a digital image, and can be implemented as any type of display panel, such as a liquid crystal display panel, an organic light emitting diode (OLED) display panel, or an electroluminescent display panel. The display panel 100 vibrates in response to the vibration of the sound generating device 200 and can output sound (SW) to the front (FD) of the display panel 100. For example, the display panel 100 can vibrate in response to the vibration of the sound generating device 200 while displaying an image and output sound (SW) to the front (FD) of the display panel 100. Alternatively, the display panel 100 can vibrate in response to the vibration of the sound generating device 200 and output sound (SW) to the front (FD) of the display panel 100 without displaying an image. Thus, the display panel 100 can display an image and output sound (SW).

[0042] For example, the display panel 100 may display images in a top emission, bottom emission, or dual emission manner depending on the structure of a pixel array layer including an anode electrode, a cathode electrode, and an organic compound layer. The top emission manner displays images by emitting visible light generated in the pixel array layer to the front of the base substrate, while the bottom emission manner displays images by emitting visible light generated in the pixel array layer to the rear of the base substrate.

[0043] The sound-generating device 200 can generate sound by using the display panel 100 as a diaphragm. The sound-generating device can be expressed as an actuator, an exciter, or a transducer, and is not limited to these terms. For example, the sound-generating device 200 can be an acoustic device that outputs sound in response to an electrical signal.

[0044] FIG. 1B is a cross-sectional view taken along line II' of FIG. 1A.

[0045] Referring to FIG. 1B, the display device 10 can include a sound-generating device 200 and a support member 300.

[0046] The supporting member 300 can support one or more of the rear surface or side surface of the display panel 100. The sound-generating device 200 can be fixed to the supporting member 300.

[0047] The support member 300 may be, for example, a cover bottom. For example, it may include a middle cabinet that surrounds the lateral or side surfaces of the display panel 100, is coupled to the cover bottom, and accommodates one side edge of the display panel 100 to support the display panel 100. For example, the middle cabinet may have a cross section shaped like a "┤". The support member 300 may include a cover bottom, or a cover bottom and a middle cabinet, but is not limited to this example structure. The support member 300 may include any structure that can support the rear or side of the display panel 100.

[0048] The support member 300 may be a plate-shaped member formed on or over the entire rear surface of the display panel 100. For example, the support member 300 may cover the entire rear surface of the display panel 100 at a distance. The support member 300 may have a flat plate shape made of glass, metal, or plastic. For example, edges or sharp corners of the support member 300 may be beveled or curved by a chamfering process or a corner-rounding process. For example, a glass support member 300 may be made of sapphire glass. For example, a metal support member 300 may be made of one or more of aluminum, aluminum alloy, magnesium alloy, and iron-nickel alloy. As another example, the support member 300 may have a laminated structure of a metal plate and a glass plate that is thinner than the glass plate and faces the rear surface of the display panel 100. In this case, the rear surface of the display device 10 may be used as a mirror surface by the metal plate. However, the material, shape, etc. are not limited to this example.

[0049] The support member 300 may also include a hole for inserting or accommodating the sound-generating device 200. For example, the hole may be drilled in a circular or polygonal shape in a predetermined region of the support member 300 along the thickness direction of the support member 300 in order to insert or accommodate the sound-generating device 200.

[0050] In this specification, the support member 300 may be expressed by other terms such as a cover bottom, a plate bottom, a back cover, a base frame, a metal frame, a metal chassis, a chassis base, an m-chassis, etc. Therefore, it may include any type of frame or plate-like structure disposed on the back of the display device as a support for supporting the display panel 100.

[0051] The adhesive member 400 may be disposed on the edges or peripheries of the display panel 100 and the support member 300. For example, the adhesive member 400 may be disposed between the rear surface of the display panel 100 and the front surface of the support member 300. The adhesive member 400 may adhere the display panel 100 and the support member 300. The adhesive member 400 may be, but is not limited to, a double-sided tape, a single-sided tape, an adhesive, a bond, or the like.

[0052] 2A and 2B are cross-sectional views of a sound-generating device according to an embodiment of the present disclosure.

[0053] Acoustic generators can be classified into a first structure in which the magnet is placed outside the coil and a second structure in which the magnet is placed inside the coil. The first structure can be classified as a dynamic type or an external magnetic type, and the second structure can be classified as a micro type or an internal magnetic type.

[0054] FIG. 2A shows the first structure, and FIG. 2B shows the second structure.

[0055] Referring to FIG. 2A, the sound generating device 200 may include plates 210, 210′, a magnet 220 on the plate 210, a center pole 230 on the plate 210, a bobbin 250 around the center pole 230, and a coil 260 wound around the outer periphery of the bobbin 250.

[0056] For example, the magnet 220 may be provided on the first plate 210, and the second plate 210' may be provided on the magnet 220. The first plate 210 and the second plate 210' may support the magnet 220 and fix the sound-generating device 200 to the support member 300. Therefore, the first plate 210 may be fixed in a support hole of the support member 300, and the magnet 220 may be fixed and supported between the first plate 210 and the second plate 210'.

[0057] At least one of the first plate 210 and the second plate 210' may be made of a material such as iron (Fe). The first plate 210 and the second plate 210' are not limited to the term "plate." For example, the first plate 210 and the second plate 210' may be expressed by other terms, such as "yoke."

[0058] The magnet 220 can be a sintered magnet such as barium ferrite, and the material can be ferric oxide (Fe2O3), barium carbonate (witherite) (BaCO3), neodymium (Nd), or strontium ferrite (Fe) with improved magnetic properties. 12 O 19 The magnets may include one or more of alloy cast magnets of Sr, aluminum (Al), nickel (Ni), cobalt (Co), etc. As another example, the neodymium magnet may be neodymium-iron-boron (Nd-Fe-B). However, embodiments are not limited to this example.

[0059] The frame 240 may be disposed on the second plate 210′ ​​along the edge of the first plate 210. The center pole 230 may be disposed in the central region of the first plate 210. The center pole 230 and the first plate 210 may be integrally formed. The center pole 230 may be pole pieces. In one example, pole pieces may be further disposed on the center pole 230.

[0060] The bobbin 250 may be wrapped around the center pole 230. The coil 260 may be wound around a certain area below the bobbin 250, for example, in the area below the bobbin 250. For example, the coil 260 may be wound around the outer surface below the bobbin 250, and a current or voice signal for generating sound may be applied to the coil 260.

[0061] The bobbin 250 may be realized as a ring (or cylindrical) structure made of, but not limited to, a material made of processed pulp or paper, aluminum, magnesium or their alloys, synthetic resin such as polypropylene, polyamide fiber, etc. The bobbin 250 and the coil 260 may be collectively referred to as a voice coil.

[0062] The damper 270 can also be disposed between a portion of the upper side of the bobbin 250 and the frame 240. The damper can also be expressed by other terms such as an edge, a spider, and a suspension, and is not limited to these terms.

[0063] FIG. 2B shows a second configuration in which the magnet is placed inside the coil.

[0064] Referring to FIG. 2B, the second structure sound generating display device 200' may include a magnet 220 on a first plate 210, a center pole 230 on the magnet 220, a bobbin 250 around the magnet 220 and the center pole 230, and a coil 260 wound around the outer periphery of the bobbin 250.

[0065] For example, the first plate 210 can be fixed to a support hole of the support member 300. The magnet 220 can be disposed on the first plate 210, and the center pole 230 can be disposed on the magnet 220. The center pole 230 can also be pole pieces. In one example, pole pieces can also be disposed on the center pole 230.

[0066] The bobbin 250 surrounds the magnet 220 and the center pole 230 , and the coil 260 can be wound around the outer surface of the bobbin 250 .

[0067] The second plate 210′ ​​may be disposed around the periphery of the first plate 210, and the frame 240 may be disposed around the periphery of the second plate 210′. For example, the damper 270 may be disposed between the frame 240 and the bobbin 250.

[0068] Compared to the first structure in which the magnet is arranged on the outside, the second structure in which the magnet is located inside has the advantage of reducing leakage magnetic flux and making it possible to reduce the overall size of the sound generating device.

[0069] The sound generating device used in the display device according to the embodiments of the present specification is not limited to the structure shown in Figures 2A and 2B. It is also possible to use a different type of sound generating device that can vibrate the display panel, for example, that can directly vibrate the display panel to generate sound.

[0070] 3A and 3B are diagrams for explaining how the sound generating device according to the first structure of the embodiment of the present specification generates sound.

[0071] 3A shows a state in which a current is flowing. Center pole 230 connected to the bottom surface of magnet 220 becomes a north pole, and second plate 210' connected to the top surface of magnet 220 becomes a south pole, generating an external magnetic field around coil 260. In this state, when a current for generating sound is applied to coil 260, an applied magnetic field is formed around coil 260, and a force that moves bobbin 250 upward is generated by the applied magnetic field and the external magnetic field. For example, when a current is applied to coil 260, an applied magnetic field is formed around coil 260, and due to the external magnetic field generated by magnet 220, the entire bobbin 250 moves upward while being guided by center pole 230 according to Fleming's left-hand rule.

[0072] Therefore, one surface of bobbin 250 contacts the rear surface of display panel 100, and the bobbin vibrates display panel 100 upward (indicated by the arrow) depending on the presence or absence of current in coil 260, generating sound waves (or acoustic waves) due to the vibration of display panel 100. In this state, when the current is stopped or current flows in the opposite direction, as shown in Figure 3B, a force is generated that moves bobbin 250 downward based on the same principle as described in Figure 3A, and display panel 100 vibrates downward (indicated by the arrow).

[0073] The damper 270 may be disposed between the frame 240 and a portion of the upper side of the bobbin 250. The damper 270 may have a wrinkled structure, e.g., elasticity, and may adjust the up-and-down vibration of the bobbin 250 by contracting and relaxing in response to the up-and-down movement of the bobbin 250. For example, the damper 270 is connected to the bobbin 250 and the frame 240, and the up-and-down vibration of the bobbin 250 may be adjusted by the restoring force of the damper 270. For example, when the bobbin 250 vibrates above or below a certain height, the bobbin 250 may return to its original position by the restoring force of the damper 270.

[0074] Therefore, depending on the direction and magnitude of the current applied to the coil 260, the display panel 100 can vibrate up and down, and this vibration can generate sound waves.

[0075] 4A and 4B are diagrams for explaining how a sound is generated by a sound generating device according to the second structure of an embodiment of the present specification.

[0076] 4A shows the state in which current is flowing. Second plate 210 becomes the south pole, and center pole 230 connected to the top surface of magnet 220 becomes the north pole, forming an external magnetic field around coil 260. The north and south poles are interchangeable. When the north and south poles are interchangeable, the winding direction of coil 260 can be changed to achieve the same operation. When a current for generating sound is applied to coil 260 in this state, an applied magnetic field is formed around coil 260, and a force that moves bobbin 250 upward is generated by the applied magnetic field and the external magnetic field. For example, when current flows through coil 260, a magnetic field is formed around coil 260, and due to the external magnetic field generated by magnet 220, the entire bobbin 250 moves upward while being guided by center pole 230 according to Fleming's left-hand rule.

[0077] Therefore, one surface of bobbin 250 is in contact with the rear surface of display panel 100, and the presence or absence of current in coil 260 causes display panel 100 to vibrate upward (indicated by the arrow), generating sound waves (or acoustic waves). In this state, when the current is stopped or current flows in the opposite direction, as shown in Figure 4B, a force is generated that moves bobbin 250 downward based on the same principle as described in Figure 4A, and display panel 100 vibrates downward (indicated by the arrow).

[0078] The damper 270 may be disposed between the frame 240 and a portion of the upper side of the bobbin 250. The damper 270 may have an elastic bellows structure, and may adjust the up-and-down vibration of the bobbin 250 by contracting and relaxing in response to the up-and-down movement of the bobbin 250. For example, the damper 270 is connected to the bobbin 250 and the frame 240, and the up-and-down vibration of the bobbin 250 may be adjusted by the restoring force of the damper 270. For example, when the bobbin 250 vibrates above or below a certain height, the bobbin 250 may return to its original position by the restoring force of the damper 270.

[0079] Therefore, the display panel 100 can vibrate up and down depending on the direction and magnitude of the current applied to the coil 260, and sound waves can be generated by this vibration.

[0080] FIG. 5 is a diagram illustrating a display device including a sound generating device according to an embodiment of the present specification.

[0081] In the embodiments of the present specification, both the sound generating device with the first structure and the sound generating device with the second structure can be applied, and the following description will be given taking the sound generating device with the second structure as an example.

[0082] 5, the sound-generating device 200 may include an expanded diameter portion 614. The expanded diameter portion 614 may be formed integrally with the first plate 210. The first plate 210 of the sound-generating device 200 may be cylindrical or non-cylindrical. One side of the first plate 210 may have a protrusion with a diameter larger than the diameter of the remaining portion of the first plate 210. The protruding region with the larger diameter may be referred to as the expanded diameter portion 614. The expanded diameter portion 614 may have an annular shape. An extension portion 612 for fixing the sound-generating device 200 may be formed in a portion of the expanded diameter portion 614.

[0083] The extension portion 612 may be configured with a screw 320 and a nut 330. The sound-generating device 200 may be coupled to the support member 300 by the screw 320 using the nut 330 fixed to the support member 300. The nut 330 may be, for example, a self-clinching nut. One example of a self-clinching nut may be a PEM nut, but this is not limited to this embodiment. This allows the sound-generating device 200 to be accommodated in the support hole 310 in the support member 300.

[0084] When a self-clinching nut is used, vibrations generated by the sound-generating device 200 can be partially absorbed by the self-clinching nut of the nut 330, thereby reducing vibrations transmitted to the support member 300. In addition, the display panel 100 can be attached or coupled to the bobbin 250 of the sound-generating device 200.

[0085] As illustrated in FIG. 5, the sound-generating device can be coupled or connected to the display panel through a support hole in the support member. Therefore, a support hole is required on the rear surface of the support member, which can allow foreign matter to enter from the outside. Furthermore, the sound-generating device is exposed on the rear surface of the support member, which can detract from the aesthetic appeal of the display. Furthermore, a protective cover is required to prevent damage to the sound-generating device exposed on the rear surface of the support member, which requires an additional process for the protective cover or increases the thickness of the sound-generating device. Therefore, the inventors of the present specification conducted several experiments to construct a sound-generating device within a display panel without coupling or connecting the sound-generating device to the support member through the support hole. Through these experiments, they recognized that the thickness of the sound-generating device must be reduced in order to construct the sound-generating device within the display panel. They recognized that a thick sound-generating device increases the thickness of the display panel, which can affect the image quality and display of the display panel and detract from the aesthetic appeal of the display. Furthermore, we recognized that achieving stereophonic sound requires the construction of multiple sound-generating devices, which necessitates reducing the thickness of the sound-generating device. Therefore, reducing the thickness of a sound-generating device requires reducing the thickness of the components included in the sound-generating device. For example, reducing the thickness of a magnet reduces the magnetic flux density, resulting in a decrease in sound pressure. Furthermore, reducing the height (or thickness) of a bobbin reduces the winding width of the coil wound around the bobbin, which weakens the magnetic force of the sound-generating device, resulting in a decrease in articulation or sound pressure. Furthermore, the wiring that transmits electrical signals to the coil can interfere with the damper, resulting in interference noise from the sound-generating device. Therefore, through several experiments, we invented a new sound-generating device with a larger area that can reduce the thickness of the sound-generating device without affecting the sound. This will be described with reference to FIGS. 6 to 12.

[0086] FIG. 6 is a diagram showing a display device including a sound generating device according to another embodiment of the present specification.

[0087] In the embodiments of the present specification, both the sound generating device with the first structure and the sound generating device with the second structure can be applied, and the following description will be given taking the second structure as an example.

[0088] 6, a display device 20 according to an embodiment of the present specification may include a display panel 100 and a sound generating device 1600. An encapsulation substrate 102 may be disposed on the rear surface of the display panel 100. For example, the encapsulation substrate 102 may protect thin film transistors and light emitting element layers disposed on the display panel 100 from external impact and may prevent moisture and oxygen from entering the light emitting element layers. The encapsulation substrate may be an encapsulation substrate, a sealing substrate, or a protective substrate.

[0089] The sound generating device 1600 may include a magnet 1620 on a yoke 1610, a center pole 1630 on the magnet 1620, a bobbin 1650 around the magnet 1620 and the center pole 1630, and a coil 1660 wound around the outer periphery of the bobbin 1650. When the coil 1660 is wound around the outer periphery of the bobbin 1650, heat generated in the coil 1660 is transferred to the bobbin 1650. The coil 1660 may be made of a material with relatively excellent heat dissipation properties to reduce image quality defects that may affect the display panel 100 due to the heat of the bobbin 1650. The bobbin 1650 vibrates up and down, causing biased vibrations. The biased vibrations of the bobbin 1650 may be affected by the weight of the bobbin 1650, and the weight of the bobbin 1650 is affected by the weight of the coil 1660. Therefore, if the weight of the coil 1660 is reduced, the biased vibration of the bobbin 1650 can be reduced. In this way, when the biased vibration of the heat bobbin 1650 is taken into consideration, the coil 1660 may be made of aluminum, which has better thermal conductivity than copper, a common coil material, has relatively good heat dissipation properties, and is relatively lighter than copper. The yoke 1610 may be a plate, and is not limited to the term.

[0090] Since aluminum forms an oxide film in air and is difficult to solder during the manufacture of the sound-generating device 1600, the coil 1660 according to the embodiment of the present disclosure may include an aluminum layer (or first metal layer) for heat dissipation and a metal outer layer (or second metal layer) surrounding the aluminum layer. In this case, the metal outer layer may include one of copper (Cu), silver (Ag), and gold (Au). For example, the coil 1660 may be a copper-clad aluminum wire covered with copper. Because the metal outer layer is formed as a thin film on the outside of the first metal layer, it does not significantly increase the weight of the coil 1660. Therefore, the coil 1660 according to the embodiment of the present disclosure may be approximately 60% lighter in weight than a coil made solely of copper material or copper wire.

[0091] The bobbin 1650 may be a structure formed from a material such as processed pulp or paper, aluminum, magnesium, or an alloy thereof, or a synthetic resin such as polyimide. For example, the bobbin 1650 may be made of a relatively lightweight polyimide film, which has excellent heat dissipation properties, to prevent localized image quality defects of the display panel 100 due to heat generated by the coil 1660. Polyimide film maintains its physical properties over a wide temperature range from -273°C to 400°C and has heat resistance, electrical insulation, flexibility, and non-flammability. Furthermore, polyimide film has excellent thermal and mechanical strength, which can improve the reliability of the bobbin 1650, and its excellent heat dissipation properties can reduce heat generation due to vibration of the bobbin 1650. For example, the polyimide film can be KAPTON, which can be the condensation of pyromellitic dianhydride and 4,4'-oxydianiline.

[0092] A frame 1640 may be disposed on the outer side of the yoke 1610. A damper 1670 may be disposed between the frame 1640 and the bobbin 1650. The description of the sound generating device 1600 is the same as that described with reference to Figures 2A and 2B, and therefore a detailed description thereof will be omitted here.

[0093] The display panel 100 may be attached or connected to the bobbin 1650 of the sound-generating device 1600 via an adhesive member 402. For example, a bobbin ring 1652 may be further included on the bobbin 1650. The bobbin ring 1652 is interposed between the bobbin 1650 and the display panel 100 to transmit vibrations of the bobbin 1650 to the display panel 100. FIG. 6 illustrates an example in which the bobbin ring 1652 is disposed over the entire bobbin 1650. However, the bobbin ring 1652 may also be disposed at a location where the bobbin 1650 is located. The bobbin ring 1652 may be attached to the display panel 100 via an adhesive member 402. The adhesive member 402 may be, but is not limited to, a double-sided tape, a single-sided tape, an adhesive, or a bond. As shown in FIG. 6, the adhesive member 402 may be formed at a portion where the sound-generating device 1600 is attached or connected to the display panel 100. However, the adhesive member 402 may be formed on the entire rear surface of the display panel 100. For example, the adhesive member 402 may be formed on the entire surface between the rear surface of the display panel 100 and the sound-generating device 1600. The partition 700 may also be disposed between the display panel 100 and the support member 300. For example, the partition 700 may be disposed between the encapsulation substrate 102 of the display panel 100 and the support member 300.

[0094] A coupling member 1710 may be disposed on the sound-generating device 1600 to position the sound-generating device 1600 within the display panel 100. The yoke 1610 may include an extension 1612. The coupling member 1710 may be disposed on the extension 1612 of the yoke 1610. For example, the thickness of the yoke 1610 may be increased to form a threaded tap, and then the yoke 1610 may be fastened with a screw. The threaded tap may be, but is not limited to, a manual tap, a machine tap, a gas tap, a master tap, or the like. For example, the coupling member 1710 may be disposed within the support member 300. The coupling member 1710 may include a screw 1720 and a nut 1730. The screw 1720 and the nut 1730 may be disposed within the support member 300, and the sound-generating device 1600 may be fixed within the support member 300 by the screw 1720 and the nut 1730. For example, the nut 1730 may be a self-clinching nut. One example of a self-clinching nut may be a PEMnut, but is not limited to this example.

[0095] For example, the sound-generating device 1600 may be coupled to the support member 300 by a nut 1730 using a press-fit method without a support hole in the support member 300. The press-fit method may be a sawtooth press-fit method, and the embodiments of the present specification are not limited to such a coupling method or shape. This allows the sound-generating device 1600 to be disposed within the display panel 100. For example, the sound-generating device 1600 may be disposed or coupled between the display panel 100 and the support member 300 by a coupling member 1710. Therefore, since the sound-generating device can be disposed or coupled within the display panel 100, support holes in the support member are not required, and foreign matter can be prevented from entering through the support holes in the support member. Furthermore, since the sound-generating device is not exposed on the back surface of the support member, a display device with an aesthetic appearance can be provided and damage to the sound-generating device can be prevented.

[0096] FIG. 7 is a diagram showing a display device including a sound generating device according to another embodiment of the present specification.

[0097] In the embodiments of the present specification, both the sound generating device with the first structure and the sound generating device with the second structure can be applied, and the following description will be given taking the second structure as an example.

[0098] 7, a display device 30 according to an embodiment of the present specification may include a display panel 100 and a sound generating device 1600. An encapsulation substrate 102 may be disposed on the rear surface of the display panel 100. For example, the encapsulation substrate 102 may protect thin film transistors and light emitting element layers disposed on the display panel 100 from external impact and may prevent moisture or oxygen from entering the light emitting element layers. The encapsulation substrate may be an encapsulation substrate, a sealing substrate, or a protective substrate.

[0099] The sound generating device 1600 may include a magnet 1620 on a yoke 1610, a center pole 1630 on the magnet 1620, a bobbin 1650 around the magnet 1620 and the center pole 1630, and a coil 1660 wound around the outer periphery of the bobbin 1650. The yoke 1610 may be a plate and is not limited to the term. A frame 1640 may be disposed on the outside of the yoke 1610. A damper 1670 may be disposed between the frame 1640 and the bobbin 1650. The description of the sound generating device is the same as that described with reference to FIGS. 2A and 2B, so a detailed description will be omitted here.

[0100] The display panel 100 may be attached to the bobbin 1650 of the sound-generating device 1600 via an adhesive member 402. For example, a bobbin ring 1652 may be further included on the bobbin 1650. The bobbin ring 1652 is interposed between the bobbin 1650 and the display panel 100 to transmit vibrations of the bobbin 1650 to the display panel 100. FIG. 7 illustrates an example in which the bobbin ring 1652 is disposed over the entire bobbin 1650. However, the bobbin ring 1652 may be disposed or connected at a certain position on the bobbin 1650. The bobbin ring 1652 may be attached to or connected to the display panel 100 via an adhesive member 402. The adhesive member 402 may be, but is not limited to, a double-sided tape, a single-sided tape, an adhesive, or a bond. As shown in FIG. 7, the adhesive member 402 may be formed at a portion where the sound-generating device 1600 is attached to or connected to the display panel 100. However, the adhesive member 402 may be formed on the entire rear surface of the display panel 100. For example, the adhesive member 402 may be formed on the entire surface between the rear surface of the display panel 100 and the sound-generating device 1600. The partition 700 may also be disposed between the display panel 100 and the support member 300. For example, the partition 700 may be disposed between the encapsulation substrate 102 of the display panel 100 and the support member 300.

[0101] A coupling member 1710 may be disposed on the sound-generating device 1600 to position the sound-generating device 1600 within the display panel 100. The frame 1640 may include an extension 1642. The coupling member 1710 may be disposed on the extension 1642 of the frame 1640. The coupling member 1710 may include a screw 1720 and a nut 1730. The screw 1720 and the nut 1730 may be disposed within the support member 300, and the sound-generating device 1600 may be fixed to the support member 300 by the screw 1720 and the nut 1730. For example, the nut 1730 may be a self-clinching nut. One example of a self-clinching nut may be a PEM nut, but this is not a limiting example.

[0102] For example, the sound-generating device 1600 can be coupled to the support member 300 by a nut 1730 using a press-fit method without a support hole in the support member 300. The press-fit method may be a sawtooth press-fit method, and the embodiments of the present specification are not limited to such a coupling method or shape. This allows the sound-generating device 1600 to be disposed within the display panel 100. For example, the sound-generating device 1600 can be disposed between the display panel 100 and the support member 300 by the coupling member 1710. Therefore, since the sound-generating device can be disposed within the display panel, there is no need to provide a support hole in the support member, and foreign matter can be prevented from entering through the support hole in the support member. Furthermore, since the sound-generating device is not exposed on the back surface of the support member, a display device with an aesthetic appearance can be provided and damage to the sound-generating device can be prevented.

[0103] The inventors recognized that the encapsulation substrate 102 disposed on the rear surface of the display panel 100 is made of a ferromagnetic material, such as invar, an alloy of iron (Fe) and nickel (Ni), and therefore the magnetic force of the magnet of the sound generating device inside the display panel is absorbed by the encapsulation substrate, resulting in a loss of magnetic force. The inventors recognized that the magnetic force of the magnet pulls the encapsulation substrate, pushing the sound generating device, preventing the sound generating device from vibrating up and down. The inventors also recognized that the magnetic force of the magnet pulls the encapsulation substrate, causing the sound generating device to stick to the encapsulation substrate, resulting in a loss of space in which the sound generating device can vibrate. Therefore, through multiple experiments, the inventors of the present specification have invented a display device that can reduce the leakage magnetic force of the sound generating device and does not reduce the space in which the sound generating device can vibrate. This will be described with reference to FIGS. 8 to 12.

[0104] FIG. 8 is a diagram showing a display device including a sound generating device according to another embodiment of the present specification.

[0105] In the embodiments of the present specification, both the sound generating device with the first structure and the sound generating device with the second structure can be applied, and the following description will be given taking the second structure as an example.

[0106] 8, a display device 40 according to an embodiment of the present specification may include a display panel 100 and a sound generating device 1600. The sound generating device 1600 may be disposed between the display panel 100 and the support member 300. The sound generating device 1600 may be disposed within the display panel 100. The description of the sound generating device is similar to that described with reference to FIGS. 2A and 2B, 6, and 7, and therefore will not be repeated here.

[0107] The sound generating device 1600 may include a magnet 1620 on a yoke 1610, a center pole 1630 on the magnet 1620, a bobbin 1650 around the magnet 1620 and the center pole 1630, and a coil 1660 wound around the outer periphery of the bobbin 1650. The yoke 1610 may be a plate and is not limited to the term. A frame 1640 may be disposed on the outer portion of the yoke 1610. A damper 1670 may be disposed between the frame 1640 and the bobbin 1650. A bobbin ring 1652 may further be disposed on the bobbin 1650. FIG. 8 illustrates an example in which the bobbin ring 1652 is disposed over the entire bobbin 1650. However, the bobbin ring 1652 may be disposed at a location where the bobbin 1650 is present.

[0108] A coupling member 1710 may be disposed on the sound-generating device 1600 to position the sound-generating device 1600 within the display panel 100. The yoke 1610 may include an extension 1612. The coupling member 1710 may be disposed on the extension 1612 of the yoke 1610. For example, the thickness of the yoke 1610 may be increased to form a threaded tap, and then the yoke 1610 may be fastened with a screw. The threaded tap may be, but is not limited to, a manual tap, a machine tap, a gas tap, a master tap, or the like. For example, the coupling member 1710 may be disposed within the support member 300. The coupling member 1710 may include a screw 1720 and a nut 1730. The screw 1720 and the nut 1730 may be disposed within the support member 300, and the sound-generating device 1600 may be fixed within the support member 300 by the screw 1720 and the nut 1730. For example, the nut 1730 may be a self-clinching nut. One example of a self-clinching nut may be a PEMnut, but is not limited to this example.

[0109] A heat dissipation member 600 may be further disposed on the rear surface of the display panel 100 to reduce or eliminate heat generated when the sound-generating device 1600 vibrates. For example, the heat dissipation member 600 may be disposed on the rear surface of the encapsulation substrate 102 via an adhesive member. The heat dissipation member 600 may be larger than the sound-generating device 1600 and configured to cover the sound-generating device 1600. The heat dissipation member 600 may have a polygonal plate or disk shape with a certain thickness, but is not limited thereto. For example, the heat dissipation member 600 may be, but is not limited to, a heat dissipation sheet or tape made of a metal material with high thermal conductivity, such as aluminum (Al), copper (Cu), silver (Ag), or an alloy thereof. Therefore, by providing the heat dissipation member 600, the impact of heat generated when the sound-generating device vibrates on the image quality of the display panel can be reduced.

[0110] The partition 700 can be disposed between the display panel 100 and the support member 300. For example, the partition 700 can be disposed between the heat dissipation member 600 disposed on the rear surface of the display panel 100 and the support member 300.

The yoke 1610 may be a plate and is not limited to the term. A frame 1640 may be disposed on the outside of the yoke 1610. A damper 1670 may be disposed between the frame 1640 and the bobbin 1650. A bobbin ring 1652 may further be disposed on the bobbin 1650. FIG. 9 illustrates an example in which the bobbin ring 1652 is disposed over the entire bobbin 1650. However, the bobbin ring 1652 may be disposed at a location where the bobbin 1650 is present.

[0115] A coupling member 1710 may be disposed on the sound-generating device 1600 to position the sound-generating device 1600 within the display panel 100. The frame 1640 may include an extension 1642. The coupling member 1710 may be disposed on the extension 1642 of the frame 1640. The coupling member 1710 may include a screw 1720 and a nut 1730.

For example, the nut 1730 may be a self-clinching nut. One example of a self-clinching nut may be a PEM nut, but this is not a limiting example.

[0116] A heat dissipation member 600 may be further disposed on the rear surface of the display panel 100 to reduce or eliminate heat generated when the sound-generating device 1600 vibrates. For example, the heat dissipation member 600 may be disposed on the rear surface of the encapsulation substrate 102 via an adhesive member.

For example, the heat dissipation member 600 may be a heat dissipation sheet or tape made of a metal material with high thermal conductivity, such as aluminum (Al), copper (Cu), silver (Ag), or an alloy thereof, but is not limited thereto. Therefore, by providing the heat dissipation member 600, the impact of heat generated when the sound-generating device vibrates on the image quality of the display panel can be reduced.

[0117] The partition 700 can also be disposed between the display panel 100 and the support member 300. For example, the partition 700 can be disposed between the heat dissipation member 600 disposed on the rear surface of the display panel 100 and the support member 300.

[0118] 10A to 10D are diagrams showing sound generating devices according to other embodiments of the present specification.

[0119] FIG. 10A shows one sound-generating device or one array sound-generating device. FIG. 10B shows a two-array configuration with two sound-generating devices, and FIG. 10C shows a four-array configuration with four sound-generating devices. FIG. 10D shows a six-array configuration with six sound-generating devices. The sound-generating device according to the embodiments of the present specification may be configured with one sound-generating device or a sound-generating device with two or more arrays, but is not limited thereto. The sound-generating device may be configured with either the first structure or the second structure described in FIGS. 2A and 2B. The sound-generating device may be a sound-generating module, and is not limited to the term.

[0120] 10A to 10D, the area of ​​the damper can be increased to reduce the thickness of the sound generator and improve the performance of the magnet. The damper can also be made of stainless steel, copper, or the like, and can serve as wiring that can apply an acoustic signal to the sound generator.

[0121] 10A, one sound-generating device 1600 may have a damper 1670 disposed on a frame 1640. One sound-generating device 1600 may be a single type. The frame 1640 may be a yoke, and is not limited to the term.

[0122] The damper 1670 may function as a wiring or power supply member, and may be configured with a first damper 1670a to which a positive power supply (or an audio signal or voice signal) is applied and a second damper 1670b to which a negative power supply (or an audio signal or voice signal) is applied. The damper 1670 may be divided horizontally, with the first damper 1670a to which a positive power supply is applied being the upper part as viewed from the front of the figure, and the second damper 1670b to which a negative power supply is applied being the lower part as viewed from the front of the figure. For example, the first damper 1670a may be connected to the first wiring 242a, and the second damper 1670b may be connected to the second wiring 242b. The first wiring 242a and the second wiring 242b may be wiring pads, and are not limited to these terms. The shape (S) of the damper 1670 may be an S-shape or a zigzag shape. For example, first damper 1670a and second damper 1670b have a length that is relatively longer than the distance between frame 1640 and bobbin 1650, thereby reducing the thickness of sound-generating device 1600. If damper 1670 is configured with diagonal lines, damage may occur due to the up-and-down movement of damper 1670, and increasing the length of damper 1670 may affect the resonant frequency. For example, by configuring the thickness of portions indicated by C and D to be constant and the widths to be different, damage at the overlapping portions can be prevented.

[0123] 10B, two sound-generating devices 1900 may have dampers 1670a and 1670b disposed on the frame 1640. The two sound-generating devices 1900 may be of a twin type.

The dampers 1670a and 1670b may be configured to function as wiring or power supply members, and may be configured as a first damper 1670a to which a positive power supply is applied and a second damper 1670b to which a negative power supply is applied. The dampers 1670a and 1670b may be separated horizontally, with the first damper 1670a to which a positive power supply is applied being the upper part as viewed from the front of the figure, and the second damper 1670b to which a negative power supply is applied being the lower part as viewed from the front of the figure. For example, the first damper 1670a may be connected to the first wiring 242a, and the second damper 1670b may be connected to the second wiring 242b. For example, the two first dampers 1670a may be integrally connected to the first wiring 242a, and the two second dampers 1670b may be integrally connected to the second wiring 242b. The shapes of the dampers 1670a and 1670b may be the same as or similar to those described in FIG. 10A.

[0125] 10C, the four sound-generating devices 2020 may have dampers 1670a, 1670b disposed on the frame 1640. The four sound-generating devices 2020 may be of a quad type.

[0126] The dampers 1670a and 1670b can be connected in parallel and in series. The dampers 1670a and 1670b can be configured to function as wiring or power supply members, and can be configured as a first damper 1670a to which a positive power supply is applied and a second damper 1670b to which a negative power supply is applied. The dampers 1670a and 1670b can be separated horizontally, with the first damper 1670a to which a positive power supply is applied being the upper or lower part as viewed from the front of the figure, and the second damper 1670b to which a negative power supply is applied being the lower or upper part as viewed from the front of the figure. Each of the first dampers 1670a can be connected to a first wiring 242a, and each of the second dampers 1670b can be connected to a second wiring 242b. For example, the two first dampers 1670a may be integrally connected to the first wiring 242a, and the two second dampers 1670b may be integrally connected to the second wiring 242b. The shapes of the dampers 1670a and 1670b may be the same as or similar to those described in FIG. 10A.

[0127] 10D, six sound-generating devices 2000 may be provided with dampers 1670 on a frame 1640. The six sound-generating devices 2000 may be of a hexa type.

[0128] The dampers 1670a and 1670b can be connected in parallel or in series. The dampers 1670a and 1670b can be configured to function as wiring or power supply members, and can be configured as a first damper 1670a to which a positive power supply is applied and a second damper 1670b to which a negative power supply is applied. The dampers 1670a and 1670b can be divided horizontally or vertically. For dampers located on the left and right sides of the figure, the first damper 1670a to which a positive power supply is applied can be the left part as viewed from the front of the figure, and the second damper 1670b to which a negative power supply is applied can be the right part as viewed from the front of the figure. The first damper 1670a located in the center of the figure can be the right part, and the second damper 1670b can be the left part. For example, each of the first dampers 1670a may be connected to the first wiring 242a, and each of the second dampers 1670b may be connected to the second wiring 242b. For example, each of the two first dampers 1670a may be integrally connected to the first wiring 242a, and each of the two second dampers 1670b may be integrally connected to the second wiring 242b. The shapes of the dampers 1670a and 1670b may be the same as or similar to those described in FIG. 10A.

[0129] Therefore, in the display device according to the embodiment of the present specification, the sound generating device can be arranged without a support hole in the support member, thereby improving the degree of freedom in arranging the sound generating device in the display device.

[0130] 11A and 11B are diagrams illustrating a sound-generating device according to another embodiment of the present specification.

[0131] Figure 11A is a top view of a sound-generating device according to another embodiment of the present specification, and Figure 11B is a rear view of a sound-generating device according to another embodiment of the present specification. Figures 11A and 11B will be explained using a two-array sound-generating device as an example.

[0132] Referring to FIG. 11A , additional structures may be disposed around or in the center of the damper 1670. For example, a first structure 1400 may be disposed around the damper 1670. The first structure 1400 may be disposed to surround the damper 1670. The first structure 1400 may reinforce the rigidity of the damper 1670. The first structure 1400 may be made of, but is not limited to, aluminum (Al) and magnesium (Mg). FIG. 11A shows a sound-generating device configured with two arrays. When a single sound-generating device is configured, the first structure may be disposed around the damper. At least one second structure 1674 may be disposed in the center of the damper 1670. For example, the second structure may include a second-first structure 1674a, a second-second structure 1674b, a second-third structure 1674c, and a second-fourth structure 1674d. The second structure can reinforce the rigidity of the center portion of the damper 1670. Fig. 11B shows a sound-generating device configured with two arrays, and when configured with one sound-generating device, at least one second structure can be disposed in the center portion of the damper 1670. Not limited to this, when configuring a sound-generating device with two or more arrays, the first structure and / or the second structure can be disposed either around the periphery or in the center portion of the damper 1670.

[0133] The first structure 1400 may further include a screw hole 1720a, which allows a sound-generating device to be positioned within the display panel. Bobbin Ring 1652 A slit 405s can be arranged on the top. , contact wearing part Materials It is for mounting , contact wearing part Material For example, the slits 405s can , contact wearing part MaterialThis can prevent deterioration of high-pitched sounds due to air bubbles during installation. The shape and number of slits 405s are not limited to those in the embodiment. As another example, slits 405s can be formed in adhesive member 402. The slits 405s can prevent deterioration of high-pitched sounds due to air bubbles during installation of adhesive member 402.

[0134] Referring to FIG. 11B, a first structure 1400 may be disposed around a yoke 1610. For example, the first structure 1400 may further enhance the rigidity of the frame or yoke. For example, the first structure 1400 may be formed by insert injection molding, but is not limited thereto. As another example, the injection molding may be fastened with screws, glue, or adhesive. The first structure 1400 may be formed from aluminum (Al) and magnesium (Mg), but is not limited thereto. The yoke 1610 may be a plate or a frame, and is not limited to these terms.

[0135] 12A and 12B are diagrams showing a display device including a sound generating device according to another embodiment of the present specification.

[0136] 12A, a display device 60 according to an embodiment of the present disclosure may include a display panel 100 and a sound generating device 1600. The sound generating device 1600 may include a magnet 1220 on a plate 1210, a center pole 1230 on the magnet 1220, a bobbin 1250 disposed around the magnet 1220 and the center pole 1230, and a coil 1260 wound around the outer periphery of the bobbin 1250.

[0137] For example, the magnet 1220 may be disposed on the plate 1210, and the center pole 1230 may be disposed on the magnet 1220. The center pole 1230 may be pole pieces. Alternatively, pole pieces may be disposed on the center pole 1230. The bobbin 1250 may be disposed to surround the magnet 1220 and the center pole 1230, and the coil 1260 may be wound around the outer periphery of the bobbin 1250. The frame 240 may be disposed on the outside of the plate 1210. The damper 1270 may be disposed between the frame 1240 and the bobbin 1250. The damper 1270 may be expressed by other terms such as an edge, and is not limited to the term. The plate 1210 may be expressed by other terms such as a yoke, and is not limited to the term.

[0138] The bobbin 1250 of the sound-generating device 1600 can be attached or connected to the display panel 100 via an adhesive member. For example, the adhesive member can be the adhesive member described in FIGS. 1, 6, and 7. For example, the adhesive member can be, but is not limited to, double-sided tape, single-sided tape, adhesive, and / or bond. The adhesive member can be formed at a portion where the bobbin 1250 of the sound-generating device 1600 is attached to the display panel 100, but is not limited to these. For example, the adhesive member can be formed on the entire rear surface of the display panel 100 or on the entire surface between the display panel 100 and the sound-generating device 1600.

[0139] A heat dissipation member may be disposed on the rear surface of the display panel 100 to reduce or eliminate heat generated when the sound-generating device 1600 vibrates. For example, the heat dissipation member may be the same as or similar to the heat dissipation member described with reference to FIGS. 8 and 9.

[0140] The structure fixes the plate 1210 of the sound generating device 1600 to the support member 300, allowing the bobbin 1250 to vibrate up and down. The plate 1210 and the support member 300 are fixed with the screws 1320, which can increase the stiffness of the sound generating device 1600. As a result, the inventors realized that even if the resonance frequency of the sound generating device 1600 is lowered, the bass range output from the sound generating device 1600 does not become lower because the plate 1210 and the support member 300 are fixed. Therefore, after multiple experiments, the inventors invented a sound generating device with a new structure that can lower the resonance frequency of the sound generating device and improve the bass range.

[0141] Therefore, since the support member 300 and the plate 1210 are connected by the screws 1320, it was recognized that in order to solve the problem of high rigidity of the sound-generating device, a structure in which the plate 1210 is not fixed to the support member 300 is required. In order to fix the sound-generating device 1600 to the support member 300, several experiments were conducted to find a method of reducing the rigidity of the plate 1210 without fixing it to the support member 300. Through several experiments, it was recognized that a structure in which the plate 1210 is not fixed to the support member 300 by the screws 1320 and the sound-generating device 1600 can be fixed to the support member 300 is required. For example, the plate 1210 can be disposed at a distance from the support member 300, and a structure can be formed between the sound-generating device 1600 and the support member 300. 12A and 12B, the plate 1210 and the support member 300 of the sound-generating device 1600 may be spaced apart, and a structure disposed between the sound-generating device 1600 and the support member 300 may be, for example, a connecting portion 1280. The connecting portion 1280 may be, for example, a bridge, a suspension, a damper, or the like, and is not limited to these terms. The connecting portion 1280 may be, for example, metal or plastic, but is not limited thereto. The metal may be, for example, stainless steel, but is not limited thereto. For example, the connecting portion 1280 may impart elasticity to the plate 1210, reducing its rigidity and lowering the resonant frequency, thereby improving the low-frequency sound of the sound-generating device 1600. This will be described with reference to the following equation (1). The resonant frequency (f0) of the vibration generated by the sound-generating device 1600 can be determined by the following equation (1).

[0142]

number

[0143] In Equation (1), k may be the stiffness (stiffness) of the object, and m may be the mass (mass) of the object. For example, the sound-generating device 1600 can lower the resonant frequency by decreasing the stiffness (k) or increasing the mass (m) of the object based on Equation (1), thereby improving the sound in the low-frequency range. The connecting unit 1280 can lower the resonant frequency by decreasing the stiffness of the sound-generating device 1600, thereby improving the sound in the low-frequency range of the sound-generating device 1600. As another example, the sound-generating device 1600 can lower the resonant frequency by decreasing the mass (m) of the object while simultaneously decreasing the stiffness (stiffness, k) of the object at a rate greater than the decrease in the mass (m).

[0144] For example, the connecting portion 1280 may be disposed between the plate 1210 and the support member 300. For example, the connecting portion 1280 may be disposed between the frame 1240 and the support member 300, and the sound-generating device 1600 is not fixed to the support member 300, thereby reducing the rigidity of the sound-generating device 1600. For example, the connecting portion 1280 may be disposed between the frame 1240 and the support member 300, and the plate 1210 is not fixed to the support member 300, thereby reducing the rigidity of the sound-generating device 1600. For example, one side of the connecting portion 1280 may be fixed to the support member 300, and the other side of the connecting portion 1280 may be connected to the frame 1240. For example, one side of the connecting portion 1280 may be fixed to the support member 300, and the other side of the connecting portion 1280 may not be fixed to the frame 1240, and may vibrate due to the vibration of the sound-generating device 1600. For example, the plate 1210 is not fixed by the connecting portion 1280 and can vibrate, so that it can vibrate with the vibration of the sound-generating device 1600. For example, the connecting portion 1280 may have a thickness that is relatively thinner than the plate 1210 or the support member 300 so that the sound-generating device 1600 vibrates up and down. For example, the connecting portion 1280 may have a thickness that is relatively thinner than the frame 1240. For example, the connecting portion 1280 may be a metal wire or a metal strap.

[0145] A coupling member 1310 may be disposed at the bottom of the support member 300. The coupling member 1310 may include a screw 1320 and a nut 1330. The nut 1330 may be, for example, a self-clinching nut. An example of a self-clinching nut may be a PEM nut, but this is not intended to be limiting. The nut 1330 may be fastened to the support member 300 in a press-fit manner, but is not limited thereto. The sound-generating device 1600 and the support member 300 may be coupled by the coupling member 1310. The connecting portion 1280 may be coupled to the screw 1320. The coupling member 1310 may be a coupling member, and is not intended to be limited by the term.

[0146] 12A , the connecting portion 1280 may be disposed between the connecting member 1310 and the frame 1240. For example, the connecting portion 1280 may be disposed between the connecting member 1310 and the lower portion of the frame 1240. For example, the connecting portion 1280 may extend from the outer periphery of the lower portion of the frame 1240 to the screw 1320. Therefore, the connecting portion 1280 may stably support the plate 1210 surrounded by the frame 1240 and may provide elasticity to the plate 1210, thereby reducing the rigidity of the sound-generating device 1600. For example, the connecting portion 1280 may provide elasticity to the plate 1210, thereby reducing the rigidity of the sound-generating device 1600, thereby causing the entire sound-generating device 1600 to vibrate. For example, the connecting portion 1280 may be deformed by the vibration of the sound-generating device 1600, thereby causing the entire sound-generating device 1600 to vibrate. For example, since the connecting portion 1280 can vibrate due to the vibration of the sound-generating device 1600, the entire sound-generating device 1600 can be vibrated. This makes it possible to provide a display device with improved low-frequency sound. In contrast, when the plate is fixed to the support member, the bobbin vibrates up and down, causing the display panel to vibrate, thereby reducing the sound pressure level of the low-frequency sound. For example, compared to when the plate is fixed to the support member, the sound-generating device of FIG. 12A can improve sound pressure by approximately 15 dB at 100 Hz.

[0147] 12B , the connecting portion 1280 may be configured in a plurality of pieces. The plurality of connecting portions 1280 may be disposed between the support member 300 and the frame 1240. For example, the plurality of connecting portions 1280 may be disposed on the same plane between the support member 300 and the frame 1240, or may be disposed spaced apart from one another. For example, a space may be formed between the plurality of connecting portions 1280. For example, a space may be formed on the same plane between the plurality of connecting portions 1280. For example, a space may be formed between the support member 300 and the plurality of connecting portions 1280. For example, a space may be formed between the sound-generating device 1600, the support member 300, and the plurality of connecting portions 1280.

[0148] For example, sound-generating device 1600 may include plate 1210, magnet 1220, center pole 1230, frame 1240, bobbin 1250, coil 1260, damper 1270, and connecting portion 1280 connected to frame 1240. Connecting portion 1280 may include grooves or holes capable of accommodating screws 1320. For example, as shown in FIG. 12B , grooves or holes capable of accommodating screws 1320 may be disposed in connecting portion 1280. For example, connecting portion 1280 may include two or more first connecting portions 1280a connected to frame 1240 and second connecting portions 1280b disposed along the outer periphery of frame 1240. This configuration may mutually complement the supporting force for frame 1240, stably support plate 1210 surrounded by frame 1240, provide elasticity to plate 1210, and reduce the rigidity of sound-generating device 1600. Without being limited to this, the sound generating device 1600 can be configured as a sound generating device including a connecting part 1280 that connects to the frame 1240, which can give elasticity to the plate 1210 and reduce the rigidity of the sound generating device 1600, thereby improving the low-frequency sound of the sound generating device 1600.

[0149] The frame 1240 may have a circular, rectangular, or rounded rectangular shape, and is not limited to a specific shape. If the frame 1240 is rectangular or rounded rectangular, the bottom of the frame 1240 may have a four-cornered rectangular shape or a rounded rectangular shape, and the connecting portions 1280 may be disposed between the screws 1320 and each of the corners of the frame 1240. For example, the connecting portions 1280 may be disposed between each of the four corners of the frame 1240 and the screws 1320. The connecting portions 1280 may be disposed around the periphery of the frame 1240 along the shape of the frame 1240, and the connecting portions 1280 disposed around the periphery of the frame 1240 may be disposed between the screws 1320 on the frame 1240. For example, if the frame 1240 is a rectangle or a rectangle with rounded corners, the connectors 1280 may be arranged around the periphery of the frame 1240 along the rectangle or rectangle with rounded corners of the frame 1240, and the connectors 1280 arranged around the periphery of the frame 1240 may be arranged between the screws 1320 corresponding to each of the four corners of the frame 1240. As another example, the connectors 1280 may be arranged on the outer periphery of the frame 1240 along the shape of the frame 1240, and the connectors 1280 arranged on the outer periphery of the frame 1240 may be arranged between the screws 1320 of the frame 1240. For example, if the frame 1240 is a square or a square with rounded corners, the connecting portion 1280 may be disposed on the outer periphery of the frame 1240 along the square or square with rounded corners of the frame 1240, and the connecting portion 1280 disposed on the outer periphery of the frame 1240 may be disposed between the screws 1320 at each of the four corners of the frame 1240. However, the connecting portion 1280 may also be disposed at a portion other than the corners of the frame 1240. For example, if the frame 1240 is a square or a square with rounded corners, the connecting portion 1280 may be disposed between the frame 1240 and the connecting member 1310, and the connecting portion 1280 may be located at any position between the frame 1240 and the connecting member 1310. For example, if the frame 1240 is circular, the link 1280 can be located between the frame 1240 and the coupling member 1310, and the link 1280 can be located anywhere between the frame 1240 and the coupling member 1310.The connecting parts 1280 disposed between each of the four corners of the frame 1240 and the screws 1320 and the connecting parts 1280 disposed on the outer periphery of the frame 1240 may be integrally formed. For example, the connecting parts 1280 disposed between each of the four corners of the frame 1240 and the screws 1320 and the connecting parts 1280 disposed on the outer periphery of the frame 1240 may be integrally formed through a laser process. However, the connecting parts 1280 may also be formed by laser, etching, or punching using a mold. Therefore, by forming a plurality of connecting parts 1280, the supporting force for the frame 1240 can be mutually complemented, the plate 1210 surrounded by the frame 1240 can be stably supported, and elasticity can be imparted to the plate 1210, thereby reducing the rigidity of the sound-generating device 1600.

[0150] 12A , a partition 700 may be disposed between the support member 300 and the display panel 100. The partition 700 may be an air gap or a space through which sound is generated when the display panel 100 vibrates. Compared to FIG. 5 , the vibration of the sound-generating device 1600 can vibrate the entire sound-generating device 1600 (V2), thereby further improving the sound output characteristics of the sound-generating device 1600. For example, the sound-generating device 1600 can vibrate the display panel 100 using the plate 1210, magnet 1220, center pole 1230, frame 1240, bobbin 1250, coil 1260, and damper 1270 to output sound, thereby further improving the sound output characteristics and providing a display device 60 with improved sound output characteristics in the low-frequency range.

[0151] FIG. 13 is a diagram showing a display device including a sound generating device according to another embodiment of the present specification.

[0152] 13, a display device 70 according to an embodiment of the present specification may include a display panel 100 and a sound-generating device 1600. The sound-generating device 1600 may include a first portion 24a, a second portion 24b, a first electrode 21, and a second electrode 23. The sound-generating device in FIG. 13 may be a film-type sound-generating device or a piezoelectric-type sound-generating device, and is not limited to these terms.

[0153] The plurality of first portions 24a may include a plurality of first portions 24a and a plurality of second portions 24b respectively disposed between the plurality of first portions 24a. Each of the plurality of first portions 24a may include a polygonal pattern. For example, each of the plurality of first portions 24a may be a line pattern having a predetermined width (or spacing), and each of the plurality of first portions 24a may be disposed spaced apart from one another so as to have the predetermined width (or spacing). For example, each of the plurality of first portions 24a may have the same size, for example, width, area, or volume, within the range of process error (or tolerance) occurring in the manufacturing process.

[0154] The sound-generating device 1600 may include a first portion 24a having piezoelectric properties and a second portion 24b having flexibility and disposed between the first portion 24a. For example, each of the plurality of first portions 24a may include an inorganic material or a piezoelectric material that vibrates due to the piezoelectric effect (or piezoelectric properties) caused by an electric field. For example, each of the plurality of first portions 24a may be expressed as, but is not limited to, an electroactive portion, an inorganic material portion, a piezoelectric material portion, or a vibrating portion.

[0155] Each of the first portions 24a may be made of a ceramic material capable of achieving relatively high vibration, or may be made of a piezoelectric ceramic having a perovskite crystal structure. The perovskite crystal structure may have piezoelectric and inverse piezoelectric effects and may be a plate-like structure with orientation. The perovskite crystal structure may be represented by the chemical formula ABO3, where A is a divalent metal element and B is a tetravalent metal element. For example, A and B may be cations, and O may be an anion. For example, the perovskite crystal structure may include at least one of PbTiO3, PbZrO3, BaTiO3, and SrTiO3, but is not limited to these.

[0156] The perovskite crystal structure can generate a piezoelectric effect by changing the polarization of centrally located ions (e.g., Ti ions in PbTiO3) due to external stress or a magnetic field. For example, the perovskite crystal structure can generate a piezoelectric effect by changing from a symmetric cubic structure to an asymmetric structure such as a tetragonal, orthorhombic, or rhombohedral structure due to external stress or a magnetic field. The morphotropic phase boundary of the asymmetric tetragonal and rhombohedral structures exhibits high polarization and facilitates polarization reorientation, resulting in excellent piezoelectric properties.

[0157] As an example, the inorganic material portion configured in each of the plurality of first portions 24a may include one or more of lead (Pb), zirconium (Zr), titanium (Ti), zinc (Zn), nickel (Ni), manganese (Mn), and niobium (Nb), but is not limited to these.

[0158] As another example, the inorganic material portion of each of the first portions 24a may include, but is not limited to, a PZT (lead zirconate titanate)-based material including lead (Pb), zirconium (Zr), and titanium (Ti), or a PZNN (lead zirconate nickel niobate)-based material including lead (Pb), zinc (Zn), nickel (Ni), manganese (Mn), and niobium (Nb). Furthermore, the inorganic material portion may include, but is not limited to, at least one of CaTiO3, BaTiO3, and SrTiO3, which do not include lead (Pb).

[0159] Each of the plurality of second portions 24b may include a polygonal pattern. Each of the plurality of second portions 24b may be disposed between the plurality of first portions 24a. The plurality of first portions 24a and the plurality of second portions 24b may be disposed (or arranged) side by side on the same plane (or the same layer). Each of the plurality of second portions 24b may be connected or bonded to an adjacent first portion 24a by being configured to fill the gap between two adjacent first portions 24a. For example, each of the plurality of second portions 24b may be a line pattern having a predetermined width (or spacing) and may be disposed side by side with the first portion 24a interposed therebetween. Each of the plurality of second portions 24b may have the same size, for example, width, area, or volume, within the range of process error (or tolerance) that occurs in the manufacturing process.

[0160] The size of the second portion 24b can be the same as or different from the size of the first portion 24a. For example, the sizes of the first portion 24a and the second portion 24b can be set according to requirements such as the vibration characteristics and / or flexibility of the sound-generating device 1600. For example, if the vibration characteristics of the sound-generating device 1600 are more important than flexibility, the size of the first portion 24a can be set larger than the size of the second portion 24b. As another example, if the flexibility of the sound-generating device 1600 is more important than the vibration characteristics, the size of the second portion 24b can be set larger than the size of the first portion 24a. Therefore, the degree of freedom in designing the sound-generating device 1600 can be improved depending on the characteristics required of the sound-generating device.

[0161] The organic material portion of each of the second portions 24b may be made of an organic material or organic polymer having flexibility compared to the inorganic material portion of the first portion 24a. For example, each of the second portions 24b may include an organic material, an organic polymer, an organic piezoelectric material, or an organic non-piezoelectric material. For example, each of the second portions 24b may be expressed as a flexible adhesive portion, an elastic portion, a bending portion, a damping portion, or a soft portion, but is not limited to these.

[0162] The organic material portion may include at least one of an organic piezoelectric material and an organic non-piezoelectric material. The organic material portion including an organic piezoelectric material can improve the overall durability of the sound-generating device 1600 by absorbing impacts on the inorganic material portion (or the first portion) and can provide a certain level of piezoelectric properties. For example, the organic piezoelectric material may be an organic material having electroactive properties. For example, the organic material portion may include at least one of PVDF (Polyvinylidene fluoride), beta-PVDF (β-Polyvinylidene fluoride), PVDF-TrFE (Polyvinylidene-trifluoroethylene), and PVDF-TrFE-CFE (Polyvinylidene-trifluoroethylene-chloro fluoro ethylene), but is not limited to these.

[0163] The organic material portion containing the organic non-piezoelectric material is formed of a curable resin composition and an adhesive containing the same, thereby absorbing impacts on the inorganic material portion (or first portion), thereby improving the overall durability of the sound-generating device 1600. For example, the organic non-piezoelectric material may include at least one of an epoxy-based polymer, an acrylic-based polymer, and a silicone-based polymer, but is not limited to these. Therefore, by alternately connecting the first portion 24a made of an inorganic material and having piezoelectric properties with the second portion 24b made of an organic material and having flexibility, the sound-generating device 1600 can have a thin film shape and a size corresponding to the display panel 100 of the display device or a size capable of achieving the vibration or acoustic characteristics set for the display panel 100.

[0164] The first electrode 21 is disposed on the first surfaces (or front surfaces) of the first portion 24a and the second portion 24b and can be electrically connected to the first surfaces of each of the first portions 24a. For example, the first electrode 21 can be made of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the transparent or semi-transparent conductive material can include, but is not limited to, indium tin oxide (ITO) or indium zinc oxide (IZO). The opaque conductive material can include, but is not limited to, aluminum (Al), copper (Cu), gold (Au), silver (Ag), molybdenum (Mo), magnesium (Mg), or an alloy thereof.

[0165] The second electrode 23 is disposed on a second surface (or back surface) opposite to the first surfaces of the first portions 24 a and the second portions 24 b, and can be electrically connected to the second surfaces of each of the plurality of first portions 24 a. For example, the second electrode 23 can be made of a transparent conductive material, a semi-transparent conductive material, or an opaque conductive material. For example, the second electrode 23 can be made of the same material as the first electrode 21.

[0166] The sound-generating device 1600 may further include a first protective film 25 and a second protective film 27 .

[0167] The first protective film 25 is disposed on the first electrode 21 and can protect the first surfaces of the first portion 24a and the second portion 24b. For example, the first protective film 25 can be a PI (polyimide) film or a PET (polyethyleneterephthalate) film, but is not limited thereto.

[0168] The second protective film 27 is disposed on the second electrode 23 and can protect the second surfaces of the first portion 24a and the second portion 24b. For example, the second protective film 27 can be, but is not limited to, a PI (polyimide) film or a PET (polyethyleneterephthalate) film.

[0169] 14A and 14B are diagrams illustrating a sound-generating device according to another embodiment of the present specification.

[0170] The sound-generating device 1800 according to the embodiments of the present specification may be a woofer-integrated sound-generating device, a hybrid sound-generating device, or a sound-generating device including a woofer, and is not limited to these terms. Fig. 14A is a front view of the sound-generating device, and Fig. 14B is a cross-sectional view of the sound-generating device.

[0171] 14A and 14B, a sound-generating device 1800 may include a first sound-generating module 1801 and a second sound-generating module 1802. For example, the first sound-generating module 1801 may be disposed behind the display panel, and the second sound-generating module 1802 may be disposed away from the rear surface of the display panel.

[0172] The sound-generating device 1800 may include a frame that can accommodate the first sound-generating module 1801 and the second sound-generating module 1802. The frame may include a lower frame 1610a that supports the undersides of the first sound-generating module 1801 and the second sound-generating module 1802 and a side frame 1610b that is coupled to the lower frame 1610a. The frame may be a yoke, and is not limited to the term.

[0173] The lower frame 1610a can support the magnet 1620. The magnet 1620 can be shared by the first sound-generating module 1801 and the second sound-generating module 1802. For example, the bobbin 1650a of the first sound-generating module 1801 and the coil 1660a around the bobbin 1650a can be arranged around the magnet 1620. For example, the second bobbin 1650b of the second sound-generating module 1802 and the second coil 1660b around the second bobbin 1650b can be arranged around the magnet 1620. For example, the lower frame 1610a and the plate 1611 can be arranged below and above the magnet 1620, respectively, to increase the magnetic flux density formed through the magnet 1620, the coil 1660a, and the second coil 1660b, thereby improving vibration characteristics. The lower frame 1610a can be a yoke, but the term is not limited to this.

[0174] The side frame 1610b is coupled to the lower frame 1610a and may include at least one hole 217 for generating sound. For example, the hole 217 may be a vent. For example, the hole 217 may output low-frequency sound generated by the diaphragm 214b of the second sound-generating module 1802 to the rear of the display panel 100 through an air gap inside the sound-generating device 1800.

[0175] The side frame 1610b is made of a conductive material and can control the magnetic flux generated by the magnet 1620. For example, the side frame 1610b can surround the magnet 1620 at a distance to concentrate the magnetic flux generated by the magnet 1620 within the second bobbin 1650b and suppress leakage of magnetic flux. The side frame 1610b may be a yoke, but is not limited to the term. The holes 217 may be formed in the side frame 1610b as well as the bottom frame 1610a, and may be formed in an area where the side frame 1610b and the bottom frame 1610a are coupled. The side frame 1610b can be connected to a support member via a coupling member 1710, such as a nut, or can be disposed between the support member and the display panel.

[0176] The first sound-generating module 1801 may include a magnet 1620 disposed on a frame, a bobbin 1650a around the magnet 1620, and a coil 1660a and a damper 1670a around the bobbin 1650a. For example, the description thereof is similar to that described in FIGS. 2A and 2B, 6, and 7 to 12, and therefore detailed description here may be omitted or simplified.

[0177] The magnet 1620 can be disposed on the lower frame 1610a. For example, the magnet 1620 can be interposed between the plate 1611 and the lower frame 1610a. The lower frame 1610a and the plate 1611 can control the magnetic flux generated by the magnet 1620. For example, by surrounding the magnet 1620 with the lower frame 1610a and the plate 1611, the magnetic flux generated by the magnet 1620 can be concentrated within the bobbin 1650a, thereby suppressing leakage magnetic flux.

[0178] The bobbin 1650a may be attached to the rear surface of the bobbin ring 1652a. For example, when a current for generating sound flows through the coil 1660a wound around the outer periphery of the bobbin 1650a, a magnetic field is formed within the first sound-generating module 1801. The magnetic field can vibrate the display panel via the bobbin ring 1652a. The bobbin ring 1652a is interposed between the bobbin 1650a and the display panel, and can transmit the vibration of the bobbin 1650a to the display panel. The first sound-generating module 1801 can output sound in the mid- to high-frequency range.

[0179] The second acoustic generating module 1802 may include a magnet 1620 arranged on the frame, a plate 1611 on the magnet 1620, a second bobbin 1650b around the magnet 1620, and a second coil 1660b and a second damper 1670b around the second bobbin 1650b.

[0180] A diaphragm 214b may be disposed on the second bobbin 1650b. For example, the diaphragm 214b may be disposed at a distance from the rear surface of the display panel to block heat generated in the second bobbin 1650b from being transferred to the display panel.

[0181] When a current for generating sound flows through the coil 1660b wound around the outer periphery of the second bobbin 1650b, a magnetic field is formed within the second sound-generating module 1802. This magnetic field vibrates the air layer or air gap around the diaphragm 214b, thereby outputting sound. For example, the front surface of the second bobbin 1650b contacts the diaphragm 214b and can vibrate the diaphragm 214b depending on the presence or absence of a current. The second sound-generating module 1802 can output sound in front of and behind the diaphragm 214b. For example, the second sound-generating module 1802 can output sound in the low-frequency range. For example, the sound generated by the diaphragm 214b of the second sound-generating module 1802 can include a first low-frequency sound propagated to the upper side of the diaphragm 214b and a second low-frequency sound propagated to the lower side of the diaphragm 214b. For example, the second sound-generating module 1802 can be a woofer, but is not limited to the term.

[0182] The magnet 1620 may be disposed on the lower frame 1610a. The plate 1611 may be disposed spaced apart from the diaphragm 214b. The second bobbin 1650b may be disposed on the rear surface of the diaphragm 214b. For example, the second bobbin 1650b may surround the magnet 1620 and the plate 1611.

[0183] The second damper 1670b can be disposed between the first sound-generating module 1801 and the second sound-generating module 1802. For example, the second damper 1670b can be disposed between the first damper 1670a of the first sound-generating module 1801 and the second bobbin 1650b of the second sound-generating module 1802. For example, the second damper 1670b can be disposed between the diaphragm 214b of the first sound-generating module 1801 and the diaphragm 214b of the second sound-generating module 1802. The diaphragm 214b may not be in physical contact with the first sound-generating module 1801. For example, the second damper 1670b can prevent acoustic interference between the first sound-generating module 1801 and the second sound-generating module 1802. An edge 1670c can be disposed on the diaphragm 214b. The edge 1670c can prevent deformation such as distortion of the diaphragm 214b when the diaphragm 214b moves up and down, thereby providing clear sound quality and improving the reliability of the sound-generating device 1800. The second damper 1670b can be a first suspension, and the edge 1670c can be a second suspension.

[0184] The magnet 1620a of the first sound-generating module 1801 and the second magnet 1620b of the second sound-generating module 1802 can have magnetic fields in opposite directions. The first sound-generating module 1801 can directly vibrate the display panel to output high-frequency sound to the front of the display panel, and the second sound-generating module 1802 can output low-frequency sound to the rear of the display panel. Therefore, by having magnetic fields in opposite directions, the first sound-generating module 1801 and the second sound-generating module 1802 can independently drive or control the vibrations of the first sound-generating module 1801 and the second sound-generating module 1802.

[0185] Therefore, the woofer-integrated sound generating device can have a woofer disposed around the sound generating device. The sound generating device can be disposed behind the display panel to generate mid- to high-frequency sounds, and the woofer can be disposed at a distance from the rear of the display panel to generate low-frequency sounds by vertical vibration. For example, the sound generating device and the woofer can be driven by applying different acoustic signals or voice signals. Therefore, the woofer-integrated sound generating device can improve low-frequency sounds.

[0186] When the sound generating devices described in FIGS. 6 to 13 are applied to a display device, sound generating devices can be configured in at least two of the three regions. For example, sound generating devices can be placed in the left and right regions of the display device, outputting left and right sounds in front of the display panel. In this case, we recognized the problem that sound can be output in the left and right directions of the display panel, but sound cannot be output in the up and down directions of the display panel. To improve sound in the up and down directions of the display panel, several sound generating devices can be placed, but this increases the thickness of the display device. Furthermore, to output stereophonic sound, existing speakers can be additionally placed around the display device. Existing speakers require the distance from the user to be adjusted according to the desired frequency, which necessitates speaker placement depending on the user's position and the position of the image. Therefore, the inventors of this specification conducted several experiments to realize a sound generating device that can generate left and right sounds and up and down sounds from images without increasing the thickness of the display device. For example, sound can be output to the left, right, top, and bottom of the display device or display panel, thereby realizing sound (acoustic). Through multiple experiments, we have invented a display device that includes a sound generating device with a new structure that can realize left and right sounds and up and down sounds, which will be described with reference to Figures 15A to 27I.

[0187] In the following embodiments, the contents explained in FIGS. 15A to 15I will be described as examples, and can be applied in the same or similar manner to the embodiments in FIGS. 16A to 27I.

[0188] 15A to 15I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0189] 15A to 15I, the display panel displays images and includes a first region 1, a second region 2, a third region 3, a fourth region 4, and a fifth region 5. For example, the rear surface of the display panel may include a first region 1 to a sixth region 6. The first region 1 to the sixth region 6 may have the same area, but are not limited thereto. For example, the first region 1 to the sixth region 6 may be arranged with the same spacing. In this configuration, all channels of the sound generating devices arranged in the first region 1 to the sixth region 6 can reproduce or output the same frequency range, thereby achieving uniform sound harmony between the channels. This reduces the difference in sound quality between when there is a sound effect (e.g., when the sound field is wide) and when there is no sound effect (e.g., when the sound field is not wide), thereby achieving uniform or consistent sound quality. As another example, the first region 1, the second region 2, and the third region 3 may have larger areas than the fourth region 4, the fifth region 5, and the sixth region 6. This configuration can enhance the bass range of the left and right stereo channels, thereby improving the sound quality of general audio without sound effects. As another example, the fourth region 4, the fifth region 5, and the sixth region 6 can have smaller areas than the first region 1, the second region 2, and the third region 3. This configuration can enhance the bass range of the channel responsible for sound effects, thereby widening the sound field, which is the space in which sound is expressed, when playing sound with sound effects, and improving the sound effects that express the location of the sound. Therefore, the sizes of the first region 1 to the sixth region 6 can be adjusted according to the desired sound range. For example, the first region 1 and the fourth region 4 can be the left region on the rear surface of the display panel. For example, the second region 2 and the fifth region 5 can be the right region on the rear surface of the display panel. For example, the third region 3 and the sixth region 6 can be the central region on the rear surface of the display panel. The same or similar explanations can be applied to FIGS. 15A to 18I.

[0190] At least one sound generating device may be arranged in at least one of the first region 1, the second region 2, the third region 3, the fourth region 4, the fifth region 5, and the sixth region 6. In the following embodiment, the sound generating device is arranged on the rear surface of the display panel. However, the sound generating device may be arranged between the display panel and the support member. For example, the sound generating device may be arranged between the rear surface of the display panel and the front surface of the support member. For example, the first sound generating device 1600L may be arranged in the first region 1 on the rear surface of the display panel, and the fourth sound generating device 1600HL may be arranged in the fourth region 4 on the rear surface of the display panel. The second sound generating device 1600R may be arranged in the second region 2 on the rear surface of the display panel, and the fifth sound generating device 1600HR may be arranged in the fifth region 5 on the rear surface of the display panel. The third sound generating device 1600C may be arranged in the third region 3 on the rear surface of the display panel. The first sound generator 1600L may be the left channel of the display panel, the fourth sound generator 1600HL may be the top left channel of the display panel, the second sound generator 1600R may be the right channel of the display panel, the fifth sound generator 1600HR may be the top right channel of the display panel, and the third sound generator 1600C may be the center channel of the display panel.

[0191] For example, the first sound-generating device 1600L may be arranged symmetrically with the fourth sound-generating device 1600HL, but is not limited to this. For example, the first sound-generating device 1600L may be aligned on the same line as the fourth sound-generating device 1600HL, but is not limited to this. For example, the second sound-generating device 1600R may be arranged symmetrically with the fifth sound-generating device 1600HR, but is not limited to this. For example, the second sound-generating device 1600R may be aligned on the same line as the fifth sound-generating device 1600HR, but is not limited to this. For example, the first sound-generating device 1600L and the fourth sound-generating device 1600HL may be arranged symmetrically with the second sound-generating device 1600R and the fifth sound-generating device 1600HR, but is not limited to this. For example, but not limited to, the first sound-generating device 1600L and the second sound-generating device 1600R can be aligned in a line with the third sound-generating device 1600C.

[0192] 15A-15I, the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR may include at least one of the oval sound-generating devices, paired sound-generating devices, circular sound-generating devices, single-type sound-generating devices, two or more arrays of sound-generating devices, and film-type sound-generating devices described in FIGS. 5-13. The oval shape may include, but is not limited to, an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape having a width different from its height. For example, in an oval bobbin, the ratio of the diameter of the major axis to the diameter of the minor axis may be 1.3:1 to 2:1. An oval bobbin can improve high-frequency sound compared to a circular one and can have excellent heat dissipation properties because it generates less heat due to vibration. For example, at least one sound-generating device can generate sound by directly vibrating the display panel. The same or similar descriptions of this can be applied to Figures 15A to 27I.

[0193] The thickness of a display device may increase due to the inclusion of several sound-generating devices. Therefore, in order to realize a thin display device, the thickness of a substrate included in the display device may be made thin. When the thickness of the substrate is thin and a partition is provided on the rear surface of the display panel or in front of the support member, a problem occurs in that when the display panel and the support member are attached to the partition, the partition makes the display panel itself or the support member uneven, resulting in a step in the display panel or the support member.

[0194] The sound waves generated by the sound generator vibrating the display panel can spread radially from the center of the sound generator and travel. These sound waves can be called progressive waves. The progressive waves are reflected by one side of the partition to form reflected waves, which travel in the opposite direction to the progressive waves. The reflected waves overlap or interfere with the progressive waves, preventing them from traveling further, forming standing waves that remain stationary at a certain position. These standing waves can reduce sound pressure and deteriorate sound output characteristics.

[0195] We realized that because a partition cannot control peaks and dips caused by standing waves, a structure for controlling these must be installed on one side of the partition. A peak is a phenomenon in which sound pressure increases at a specific frequency, while a dip is a phenomenon in which low sound pressure occurs due to the suppression of a characteristic frequency. Peaks and dips can reduce the acoustic output characteristics of a sound generator. A structure for controlling peaks and dips must be designed to prevent wave phenomena and easily control peaks and dips caused by standing waves. This structure was not simply implemented, but was achieved through several experiments. Therefore, pads can be installed on the partition to reduce peaks and dips caused by standing waves generated in the vertical direction of the sound generator. Pads can also reduce the reduction in sound pressure caused by standing waves, which are generated by the interference of reflected and traveling waves. However, the shape of the pad can cause noticeable shapes on the display panel screen, resulting in an uneven appearance due to the display panel or support member being uneven. This phenomenon may be referred to as an uneven or wavy phenomenon of the display panel or the support member (hereinafter referred to as the "wavy phenomenon"), and is not limited to the term. Therefore, several experiments were conducted on the shape of the partition. Through these experiments, it was recognized that the partition must be arranged according to the shape of the display panel 100. For example, the partition may have a rectangular shape, but is not limited thereto and may be changed according to the shape of the display panel. In the case where the display panel is a curved display panel or a curved display panel, the partition may have a curved shape. Therefore, by arranging the partition according to the shape of the display panel, it is possible to reduce the tendency of the display panel 100 to be pulled in when the display panel 100 and the support member 300 are attached, thereby preventing the wavy phenomenon.

[0196] The shape of the pad may be configured to prevent a wave phenomenon caused by the retraction of the display panel 100 when the pad disposed on the support member 300 is attached to the display panel 100. Alternatively, the shape of the pad may be configured to prevent a wave phenomenon caused by the retraction of the display panel 100 when the pad disposed on the display panel 100 is attached to the support member 300. For example, it is necessary to easily control peak and dip phenomena caused by standing waves of the sound generating device and to prevent a wave phenomenon. Through several experiments, the pad was realized in a square shape or a square shape with rounded ends. This will be described with reference to FIGS. 15B to 15I. The description thereof may be applied identically or similarly to FIGS. 16A to 27I.

[0197] Referring to FIG. 15B , a partition may be further configured around the sound-generating device. The partition may be an air gap or space where sound is generated when the display panel 100 is vibrated by the sound-generating device. The air gap or space where sound is generated and transmitted may be referred to as a partition. The partition can separate sounds or separate channels, and can block or reduce the generation of unclear sounds due to sound interference. The partition may be an enclosure or a baffle, and is not limited to these terms. In the following embodiments, the partition is disposed on a support member as an example. However, it may also be disposed on the back of the display panel. To illustrate the sound-generating device and the partition, the partition is disposed on a support member as an example. For example, when the partition is disposed on a support member, the partition disposed on the display panel can reduce the impact on image quality of the display panel.

[0198] Partitions can be arranged to separate left and right sounds output from a sound generating device arranged behind the display panel. For example, partitions can be arranged between the display panel 100 corresponding to the first region 1 to the sixth region 6 of the display panel 100 and the support member 300. For example, the fourth partition 1701 can be arranged between the first region 1 and the fourth region 4 and the third region 3. For example, the fourth partition 1701 can be arranged between the first region 1 and the fourth region 4 and the third region 3 and the sixth region 6. The fifth partition 1702 can be arranged between the second region 2 and the fifth region 5 and the third region 3. For example, the fifth partition 1702 can be arranged between the second region 2 and the fifth region 5 and the third region 3. The fourth partition 1701 and the fifth partition 1702 can separate the left and right sounds or left and right channels generated by the first sound generating device 1600L and the fourth sound generating device 1600HL from the second sound generating device 1600R and the fifth sound generating device 1600HR. The fourth sound generating device 1600HL and the fifth sound generating device 1600HR are further configured to achieve stereophonic or spatial sound. However, the inventors recognized that partitions must be implemented to separate the sounds or channels generated by the fourth sound generating device 1600HL and the fifth sound generating device 1600HR from the sounds or channels generated by the first sound generating device 1600L, the second sound generating device 1600R, and the third sound generating device 1600C. When the fourth partition 1701 and the fifth partition 1702 are arranged, the inventors recognized that while it is possible to separate the left and right sounds or left and right channels, it is not possible to separate the upper sounds or upper channels. In order for the sound generating devices disposed in the rear area of ​​the display panel to generate independent sounds in each area, the inventors recognized that a partition capable of generating sounds from each sound generating device must be realized. Therefore, the inventors of the present specification realized the partition through several experiments, which will be described below.

[0199] The partitions are implemented to separate channels on the upper (top or height) side of the display panel from channels on the lower (bottom) side of the display panel. For example, the first partition 1721 can separate channels on the upper (top or height) side of the display panel from channels on the lower (bottom) side of the display panel. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound generator 1600HL and the fifth sound generator 1600HR arranged above the display panel from the sounds or channels generated by the first sound generator 1600L, the second sound generator 1600R, and the third sound generator 1600C arranged below the display panel. The second partition 1722 can separate the channels on the lower (bottom) side of the display panel from the woofers. For example, the second partition 1722 can be arranged below the first sound generator 1600L, the second sound generator 1600R, and the third sound generator 1600C. For example, the second partition 1722 can separate the sounds or channels generated by the first sound generating device 1600L, the second sound generating device 1600R, and the third sound generating device 1600C from the first woofer (W1) and the second woofer (W2).

[0200] The first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed on the support member 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed on the upper surface of the support member 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed between the display panel 100 and the support member 300. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be disposed between the rear surface of the display panel 100 and the upper surface of the support member 300.

[0201] The first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of any one of, but not limited to, double-sided tape, double-sided foam pads, single-sided tape, single-sided foam pads, adhesive, and bond. If the partitions are made of double-sided tape or double-sided foam pads, adhesion between the rear surface of the display panel 100 and the upper surface of the support member 300 can be improved. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of an elastic material that can be compressed to a certain extent. For example, the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702 may be made of, but not limited to, polyurethane, polyolefin, and polyethylene.

[0202] The fourth sound-generating device 1600HL can be configured in the fourth region 4 and the fifth sound-generating device 1600HR can be configured in the fifth region 5, and no sound-generating device can be configured in the sixth region 6. As a result, the vibrations of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR are attenuated or absorbed in the sixth region 6 of the display panel 100, so that the transmission of sound from the fourth region 4 to the fifth region 5 can be blocked or reduced, and the transmission of sound from the fifth region 5 to the fourth region 4 can be blocked or reduced. Therefore, it is possible to reduce deterioration in sound quality caused by interference between the sounds generated by the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR, and it is possible to further improve the acoustic characteristics in the mid- to high-frequency range.

[0203] 15B, a partition may not be disposed around the periphery of the support member 300. The support member 300 and the display panel 100 may be bonded to each other using the adhesive member described in FIG. 1B around the periphery of the support member 300, and the adhesive member may function as a partition.

[0204] When arranging the first partition 1721, the second partition 1722, the fourth partition 1701, and the fifth partition 1702, the first partition 1721 and the second partition 1722 may be arranged first, followed by the fourth partition 1701 and the fifth partition 1702. As another example, the fourth partition 1701 and the fifth partition 1702 may be arranged first, followed by the first partition 1721 and the second partition 1722, and the order of arrangement does not limit the contents of the specification. In the following embodiment, an example is shown in which the first partition 1721 and the second partition 1722 are arranged first, followed by the fourth partition 1701 and the fifth partition 1702, but the present invention is not limited to this. The content of this description may be applied equally or similarly to the following embodiment.

[0205] Therefore, the first sound generating device 1600L and the fourth sound generating device 1600HL are arranged in a first region 1 and a fourth region 4, which are left regions on the rear surface of the display panel 100, and can vibrate the left region of the display panel 100. The second sound generating device 1600R and the fifth sound generating device 1600HR are arranged in a second region 2 and a fifth region 5, which are right regions on the rear surface of the display panel 100, and can vibrate the right region of the display panel 100. The third sound generating device 1600C is arranged in a third region 3, which is a central region on the rear surface of the display panel 100, and can vibrate the central region of the display panel 100. The first sound generating device 1600L, the second sound generating device 1600R, the third sound generating device 1600C, the fourth sound generating device 1600HL, and the fifth sound generating device 1600HR can each receive a different vibration signal and be driven independently. For example, the first sound-generating device 1600L and the fourth sound-generating device 1600HL can generate sound by using the left region of the rear surface of the display panel 100 as a diaphragm, and the second sound-generating device 1600R and the fifth sound-generating device 1600HR can generate sound by using the right region of the rear surface of the display panel 100 as a diaphragm. The third sound-generating device 1600C can generate sound by using the central region of the display panel 100 as a diaphragm. A woofer can be disposed to improve low-frequency sound. For example, at least one woofer can be disposed below the first sound-generating device 1600L and the second sound-generating device 1600R. For example, the first woofer (W1) can be disposed below the first region 1 of the display panel 100. For example, the first woofer (W1) can be disposed below the first sound-generating device 1600L. For example, the second woofer (W2) can be disposed below the second region 2 of the display panel 100. For example, the second woofer (W2) can be disposed below the second sound generating device 1600R. Therefore, the first woofer (W1) and the second woofer (W2) can output sounds in the low frequency range.The first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the fourth sound generator 1600HL, and the fifth sound generator 1600HR can output sound in the 80 Hz to 40 kHz range, and the first woofer (W1) and the second woofer (W2) can output sound below 80 Hz. Therefore, the display device can output 5.1-channel sound. Furthermore, since sound generators are additionally configured above and below the horizontal direction of the display panel compared to the sound generators arranged on the left and right, the left and right sounds and the top and bottom sounds can be improved, providing the user with the same sound field experience as actual sound. For example, by further configuring the fourth sound generator 1600HL and the fifth sound generator 1600HR, sound can be output from above the display panel and output above or upward from the display panel, thereby providing a display device that can realize three-dimensional sound including left and right sounds and top and bottom sounds. Therefore, left / right sounds and up / down sounds for left / right images and up / down images can be realized, and real stereophonic sound (e.g., real sound) including stereophonic left / right sounds and up / down sounds can be realized for the user, thereby providing real sound rather than virtual sound. As a result, real stereophonic sound or surround sound (e.g., real sound) including stereophonic left / right sounds and up / down sounds can be realized for the user, thereby improving the sense of realism. Therefore, even in devices such as movie theaters, private movie theaters, and televisions, users can simultaneously experience real sound and images similar to or identical to reality, for example, a real AV (Audio Visual) or Dolby sound system. The same or similar explanation can be applied to FIGS. 15B to 27I. Furthermore, when multiple thick sound-generating devices are used, the display device becomes thicker due to the thickness of the sound-generating devices.As described with reference to FIGS. 6 to 11B, the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can be disposed within the display panel 100. This reduces the thickness of the sound-generating devices, thereby providing a display device that provides a user with a beautiful appearance. As described with reference to FIGS. 12A and 12B, the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can be configured as sound-generating devices with improved bass frequencies, thereby providing a display device that can achieve left / right and up / down sounds with improved bass frequencies. 13, the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can be configured as film-type sound-generating devices, which can reduce the thickness of the sound-generating device and provide a display device that gives a beautiful impression to the user. For example, the mid-range band can be 200 Hz to 3 kHz, the treble band can be 3 kHz or more, and the bass band can be 200 Hz or less, but are not limited to these ranges.

[0206] Referring to FIG. 15C , a first partition 1721, a fourth partition 1701, and a fifth partition 1702 may be configured, and a partition 1750 may be disposed between the support member 300 and the display panel 100. For example, the partition 1750 may be disposed at an end or edge of the support member 300. For example, the partition 1750 may be disposed at an end or edge of the front surface of the support member 300. The partition 1750 may also occupy the entire area of ​​the four sides of the outer periphery of the front surface of the support member 300. As another example, the partition 1750 may be disposed at an end or edge of the rear surface of the display panel. The partition 1750 may also occupy the entire area of ​​the four sides of the outer periphery of the rear surface of the display panel. The partition 1750 may also occupy the entire area of ​​the four sides of the outer periphery of the front surface of the support member 300 or the entire area of ​​the four sides of the outer periphery of the rear surface of the display panel. The partition 1750 may also occupy the entire area of ​​the rear surface of the display panel or the front surface of the support member 300. For example, the partition 1750 may be arranged to surround the first sound generating device 1600L to the fifth sound generating device 1600HR. The partition 1750 may be arranged to follow the shape of the display panel to prevent a wave phenomenon of the display panel. For example, if the partition 1750 is an adhesive member for attaching the display panel 100 and the support member 300 described in FIG. 1B, the adhesive member described in FIG. 1B may be omitted, and the partition 1750 may function as the adhesive member. Alternatively, the adhesive member for attaching the display panel 100 and the support member 300 may be configured on the rear surface of the display panel 100 or the front surface of the support member 300.

[0207] When arranging the first partition 1721, the fourth partition 1701, the fifth partition 1702, and the partition 1750, the first partition 1721 may be arranged first, and then the fourth partition 1701 and the fifth partition 1702 may be arranged. As another example, the first partition 1721 may be arranged first, and then the fourth partition 1701 and the fifth partition 1702 may be arranged, and then the partition 1750 may be arranged. The order of arrangement does not limit the contents of the specification. The partition 1750 may be arranged first in the vertical direction of the support member 300, and then in the horizontal direction of the support member 300. As another example, the partition 1750 may be arranged first in the horizontal direction of the support member 300, and then in the vertical direction of the support member 300. The order of arrangement does not limit the contents of the specification. In the following embodiment, the first partition 1721 is arranged first, and then the fourth partition 1701 and the fifth partition 1702 are arranged after the partition 1750, but the present invention is not limited to this. The content of this case can be applied equally or similarly to the following embodiment.

[0208] 15D and 15E , the shapes of the first partition 1721 and the second partition 1722 may be configured differently. The first partition 1721 and the second partition 1722 may be configured to have a shape different from the shape of the display panel. For example, the first partition 1721 and the second partition 1722 may be non-flat or non-linear. For example, the first partition 1721 and the second partition 1722 may have a sawtooth shape, a triangular shape, or a triangular shape with a rounded tip. For example, the sawtooth of the first partition 1721 and the second partition 1722 may be oriented to face the sound-generating device. For example, if the first partition 1721 and the second partition 1722 are triangular, the tip of the triangle may be oriented to face the sound-generating device. For example, if the first partition 1721 and the second partition 1722 have a rounded triangular shape, the tip of the rounded triangle can be configured to face the sound-generating device. For example, referring to FIG. 15D , if the first partition 1721 has a rounded triangular shape, the tip of the rounded triangle can be configured to face the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR. For example, referring to FIG. 15D , if the second partition 1722 has a rounded triangular shape, the tip of the rounded triangle can be configured to face one or more of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. Therefore, by configuring the shape of the partitions to face at least one sound-generating device, peaks and dips caused by standing waves of the sound-generating devices can be controlled, and wave phenomena in the display panel can be reduced. By changing the shape of the partition, acoustic interference such as diffuse reflection from an acoustic generator can be resolved.

[0209] If the partitions are not flat or linear, they can disperse standing waves, for example, sawtooth, triangular, and rounded triangular shapes, which can disperse standing waves in multiple directions, thereby further improving the acoustic output characteristics.

[0210] 15E, the first partition 1721 may be configured with, but is not limited to, two partitions. For example, the first partition 1721 may include a first partition 1721a and a second partition 1721b, and may be configured with a rounded triangular shape. The tip of the triangle or rounded triangular shape of the first partition 1721a may be configured to face one or more of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR. The tip of the triangle or rounded triangular shape of the first partition 1721b may be configured to face one or more of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. The tips of the triangle or rounded triangle shape of the second partition 1722 can be configured to face the first sound generating device 1600L, the second sound generating device 1600R, and the third sound generating device 1600C, thereby controlling peak and dip phenomena caused by standing waves of the sound generating devices and reducing wave phenomena in the display panel.

[0211] 15F to 15I, a pad may be further configured on at least one side of the partition. Standing waves, which cause a decrease in sound pressure, are likely to occur at points where the magnitudes of forward and reflected waves are large. Therefore, the pad may be placed at a location where the sound waves arriving from the sound-generating device are strongest. For example, the pad may be placed on one or more sides of the partition where the strongest sound waves arrive, facing the sound-generating device.

[0212] 15F , pads may be arranged on at least one side of the fourth partition 1701 so as to face one or more of the first sound-generating device 1600L and the fourth sound-generating device 1600HL. For example, a 1-3 pad 713 and a 1-4 pad 714 may be arranged on at least one side of the fourth partition 1701 so as to face the first sound-generating device 1600L. A 1-1 pad 711 and a 1-2 pad 712 may be arranged on the side opposite the 1-3 pad 713 and the 1-4 pad 714. The 1-1 pad 711 to the 1-4 pad 714 may each be two pads, but is not limited to this. One or more of the 1-1 pad 711 to the 1-4 pad 714 may each be one, two, or three or more. For example, the 4-3 pad 723 and the 4-4 pad 724 can be arranged on at least one side of the fourth partition 1701 so as to face the fourth sound-generating device 1600HL. The 4-1 pad 721 and the 4-2 pad 722 can be arranged on the side opposite the 4-3 pad 723 and the 4-4 pad 724. The 4-1 pad 721 to the 4-4 pad 724 can be configured in pairs, but this is not limited to this. One, two, or three or more of the 4-1 pad 721 to the 4-4 pad 724 can also be configured in pairs. For example, the 3-1 pad 911 can be arranged on at least another side of the fourth partition 1701 so as to face the third sound-generating device 1600C. One or more 3-1 pads 911 can be arranged.

[0213] Pads can be arranged on at least one side of the fifth partition 1702 so as to face one or more of the second sound-generating device 1600R and the fifth sound-generating device 1600HR. For example, a 2-1 pad 811 and a 2-2 pad 812 can be arranged on at least one side of the fifth partition 1702 so as to face the second sound-generating device 1600R. A 2-3 pad 813 and a 2-4 pad 814 can be arranged on the side opposite the 2-1 pad 811 and the 2-2 pad 812. While FIG. 15F shows two pads, the 2-1 pad 811 to the 2-4 pad 814 may be arranged in pairs, and one or more of the 2-1 pad 811 to the 2-4 pad 814 may be arranged in pairs. For example, the 5-1 pad 821 and the 5-2 pad 822 can be arranged on at least one side of the fifth partition 1702 so as to face the fifth sound-generating device 1600HR. The 5-3 pad 823 and the 5-4 pad 824 can be arranged on the side opposite the 5-1 pad 821 and the 5-2 pad 822. The 5-1 pad 821 to the 5-4 pad 824 can be configured in pairs, but this is not limited to this. One, two, or three or more of the 5-1 pad 821 to the 5-4 pad 824 can also be configured in pairs. For example, the 3-3 pad 913 can be arranged on at least another side of the fifth partition 1702 so as to face the third sound-generating device 1600C. One or more 3-3 pads 913 can be arranged. The 3-3 pad 913 can be arranged on the side opposite the 3-1 pad 911.

[0214] Pads may be arranged on at least one side of the first partition 1721 to face one or more of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. For example, a 1-5 pad 715 may be arranged on at least one side of the first partition 1721 to face the first sound-generating device 1600L. For example, a 2-5 pad 815 may be arranged on at least one side of the first partition 1721 to face the second sound-generating device 1600R. For example, a 3-5 pad 915 may be arranged on at least one side of the first partition 1721 to face the third sound-generating device 1600C. For example, a 4-6 pad 726 may be arranged on at least one side of the first partition 1721 to face the fourth sound-generating device 1600HL. For example, the 5-6 pad 826 can be arranged on at least one side of the first partition 1721 so as to face the fifth sound-generating device 1600HR. The 1-5 pad 715, the 2-5 pad 815, the 3-5 pad 915, the 4-6 pad 726, and the 5-6 pad 826 can also be configured as one or more. For example, the 4-5 pad 725 can be arranged on the side opposite the 4-6 pad 726, and the 4-5 pad 725 can be arranged so as to face the fourth sound-generating device 1600HL. The 5-5 pad 825 can be arranged on the side opposite the 5-6 pad 826, and the 5-5 pad 825 can be arranged so as to face the fifth sound-generating device 1600HR.

[0215] For example, the 1-6 pad 716 can be arranged on at least one side of the second partition 1722 so as to face the first sound-generating device 1600L. For example, the 2-6 pad 816 can be arranged on at least one side of the second partition 1722 so as to face the second sound-generating device 1600R. For example, the 3-6 pad 916 can be arranged on at least one side of the second partition 1722 so as to face the third sound-generating device 1600C. The 1-6 pad 716, the 2-6 pad 816, and the 3-6 pad 916 can also be configured as one or more. For example, the 1-5 pad 715 can be arranged on the side opposite the 1-6 pad 716, and the 1-5 pad 715 can be arranged so as to face the first sound-generating device 1600L. The 2-5 pad 815 can be arranged on the side opposite the 2-6 pad 816, and the 2-5 pad 815 can be arranged to face the second sound-generating device 1600R. The 3-5 pad 915 can be arranged on the side opposite the 3-6 pad 916, and the 3-5 pad 915 can be arranged to face the third sound-generating device 1600C.

[0216] In the embodiment, the sizes of the 1-1 pads 711 to 1-4 pads 714 are shown to be larger than the 1-5 pads 715 and 1-6 pads 716, respectively, but the size of the pads is not a limitation of the present specification. For example, the sizes of the 1-1 pads 711 to 1-4 pads 714 may be smaller or the same as the 1-5 pads 715 and 1-6 pads 716, respectively. The sizes of the other pads may be the same or similar. In FIG. 15F, a partition may not be disposed around the periphery of the support member 300. The display panel 100 may be attached to the periphery of the support member 300 using the adhesive member described in FIG. 1B, and the adhesive member may be a partition.

[0217] Referring to FIG. 15G, the partition 1750 may include a first partition 1721, a fourth partition 1701, a fifth partition 1702, and a partition 1750. For example, the partition 1750 may be arranged to surround the first sound-generating device 1600L to the fifth sound-generating device 1600HR. For example, the partition 1750 may include one or more pads on its sides. On one side of the partition 1750, a 4-5 pad 725 may be arranged to face the fourth sound-generating device 1600HL, and a 5-5 pad 825 may be arranged to face the fifth sound-generating device 1600HR. On the other side of the partition 1750, a 1-6 pad 716 may be arranged to face the first sound-generating device 1600L, a 3-6 pad 916 may be arranged to face the third sound-generating device 1600C, and a 2-6 pad 816 may be arranged to face the second sound-generating device 1600R. By configuring the partition 1750, it is possible to improve the fixing force of the sound generating device disposed behind the display panel and reduce sound leakage from the edge or margin of the display panel, thereby improving the sound output characteristics. The remaining configuration is the same as or similar to that of Fig. 15F, so detailed description will be omitted.

[0218] For example, if the partition 1750 is an adhesive member for attaching the display panel 100 and the support member 300 described in Fig. 1B, the adhesive member described in Fig. 1B can be omitted. Alternatively, the adhesive member for attaching the display panel 100 and the support member 300 can be formed on the rear surface of the display panel 100 or on the support member 300.

[0219] 15H and 15I, the first partition 1721 and the second partition 1722 may include at least one vent. The vent may be disposed to reduce the reduction in sound pressure due to standing waves generated by the interference of reflected and traveling waves. The vent may be formed on one or more sides of the partition where the strongest sound waves arrive, and may be configured to face the sound-generating device. The remaining configuration is the same or similar to that of FIG. 15F, and therefore a detailed description thereof will be omitted.

[0220] 15H, the first partition 1721 may include one or more vent portions. For example, the first partition 1721 may include a first vent portion 701 facing the first sound-generating device 1600L and a second vent portion 702 facing the second sound-generating device 1600R. The first partition 1721 may also include a third vent portion 703 facing the third sound-generating device 1600C. The reduction in sound pressure due to standing waves of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR can be reduced by the fourth-fifth pad 725 and the fifth-fifth pad 825.

[0221] The second partition 1722 may include one or more vents. For example, the second partition 1722 may include a fourth vent 704 facing the first sound-generating device 1600L and a fifth vent 705 facing the second sound-generating device 1600R. The second partition 1722 may also include a sixth vent 706 facing the third sound-generating device 1600C. The vents may have an open structure at the center of the sound-generating device. Without being limited thereto, they may have a "V"-shaped, closed structure. Having an open vent at the center of the sound-generating device has the advantage of reducing material costs compared to having a closed structure. Through acoustic property experiments, the inventors confirmed that there is little or no difference in acoustic properties between a vent with an open structure and a vent with a closed structure at the center of the sound-generating device. Therefore, by including one or more vents in the first partition 1721 and the second partition 1722, it is possible to reduce the phenomenon of reduction in sound pressure due to standing waves in the sound generating device.

[0222] Referring to FIG. 15I, the first partition 1721 and the second partition 1722 may include one or more vents, and a partition 1750 may be arranged. For example, a fourth-fifth pad 725 may be arranged on one side of the partition 1750 so as to face the fourth sound-generating device 1600HL, and a fifth-fifth pad 825 may be arranged so as to face the fifth sound-generating device 1600HR. Configuring the partition 1750 can improve the fixing strength of the sound-generating device arranged behind the display panel and reduce sound leakage from the edge or margin of the display panel, thereby improving the sound output characteristics. As another example, as shown in FIG. 15G, the partition 1750 may be arranged, and the first partition 1721 may include one or more vents. The remaining configuration is the same as or similar to that of FIG. 15H, and therefore detailed description thereof will be omitted.

[0223] As described in Figures 15H and 15I, since the end of the support member 300 does not have a vent portion, the retraction of the display panel can be reduced when the display panel and the support member 300 are attached, thereby preventing the wave phenomenon.

[0224] 16A to 16I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0225] 16A to 16I, a first woofer-integrated sound-generating device (W3) can be arranged in the first region 1, and a second woofer-integrated sound-generating device (W4) can be arranged in the second region 2. The first woofer-integrated sound-generating device (W3) and the second woofer-integrated sound-generating device (W4) are the same as those described in FIGS. 14A and 14B, so their description will be omitted here. Descriptions of the same content as those described in FIGS. 16A to 16I can be omitted or simplified.

[0226] The first woofer-integrated sound-generating device (W3) and the second woofer-integrated sound-generating device (W4) are sound-generating devices integrated with the woofers, which has the advantage of eliminating the need for separate woofers. The first woofer-integrated sound-generating device (W3) and the second woofer-integrated sound-generating device (W4) can output sound in the 60 Hz to 40 kHz range, while the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can output sound in the 80 Hz to 40 kHz range. Therefore, the display device can output 5.1-channel sound. Furthermore, compared to the sound-generating devices arranged left and right, the additional sound-generating devices arranged above and below can improve the left and right sound and the top and bottom sound, providing the user with the same sound field experience as an actual sound. For example, by further configuring the fourth sound generating device 1600HL and the fifth sound generating device 1600HR, sound can be output from the upper side of the display panel, thereby providing a display device that can realize three-dimensional sound including left and right sounds and up and down sounds. Therefore, left and right sounds and up and down sounds can be realized for left and right images and up and down images, and real three-dimensional sound (e.g., real sound) including three-dimensional left and right sounds and up and down sounds can be realized for the user, thereby providing real sound rather than virtual sound. This allows the user to realize real three-dimensional sound (e.g., real sound) including three-dimensional left and right sounds and up and down sounds, thereby enhancing the sense of realism. Therefore, even in devices such as movie theaters, private cinemas, and televisions, users can simultaneously experience real sound and images similar to or identical to reality, for example, a real AV (Audio Visual) or Dolby sound system experience.As described with reference to FIGS. 6 to 11B, the first woofer-integrated sound-generating device (W3), the second woofer-integrated sound-generating device (W4), the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can be disposed within the display panel 100. This reduces the thickness of the sound-generating devices, thereby providing a display device that provides a user with a beautiful appearance. As described with reference to FIGS. 12A and 12B, the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, and the fifth sound-generating device 1600HR can be configured as sound-generating devices with improved bass frequencies, thereby providing a display device that can achieve left-right and up-down sounds with improved bass frequencies. As described in FIG. 13, the first sound generating device 1600L, the second sound generating device 1600R, the third sound generating device 1600C, the fourth sound generating device 1600HL, and the fifth sound generating device 1600HR can be configured as film-type sound generating devices, which can reduce the thickness of the sound generating device and provide a display device that can give a beautiful impression to the user.

[0227] 16A to 16I, the first woofer-integrated sound-generating device (W3) can be arranged asymmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged asymmetrically with the fifth sound-generating device 1600HR. This configuration can reduce acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the fourth sound-generating device 1600HL. In addition to vibrations from the sound source being reproduced, unnecessary acoustic reinforcement or cancellation interference caused by external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of the first woofer-integrated sound-generating device (W3) and the fourth sound-generating device 1600HL can prevent this and reproduce natural sound that is close to the original sound. It reduces acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and the vibrations and standing waves generated by the fifth sound generator 1600HR. In addition to vibrations from the sound source being reproduced, unnecessary acoustic reinforcement or cancellation interference caused by external interference can cause sound distortion and deterioration of sound quality, but the asymmetrical structure of the second woofer-integrated sound generator (W4) and the fifth sound generator 1600HR prevents this and reproduces natural sound close to the original sound.

[0228] Referring to FIGS. 16F and 16G, the first-fifth pad 715 and the fourth-sixth pad 726 can be arranged asymmetrically, and the second-fifth pad 815 and the fifth-sixth pad 826 can be arranged asymmetrically. As another example, the first woofer-integrated sound-generating device (W3) can be arranged symmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged symmetrically with the fifth sound-generating device 1600HR. This configuration allows the sound reproduction positions to be aligned on the same line, creating the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the sound position, thereby improving the sense of sound localization. Referring to FIGS. 16F and 16G, the first-fifth pad 715 and the fourth-sixth pad 726 can be arranged symmetrically, and the second-fifth pad 815 and the fifth-sixth pad 826 can be arranged symmetrically.

[0229] 16F, pads may be arranged on at least one side of the first partition 1721 to face one or more of the first woofer-integrated sound-generating device (W3), the second woofer-integrated sound-generating device (W4), and the third sound-generating device 1600C. For example, a first-fifth pad 715 may be arranged on at least one side of the first partition 1721 to face the first woofer-integrated sound-generating device (W3). For example, a second-fifth pad 815 may be arranged on at least one side of the first partition 1721 to face the second woofer-integrated Hengyang sound-generating device (W4). For example, a third-fifth pad 915 may be arranged on at least one side of the first partition 1721 to face the third sound-generating device 1600C. The first-fifth pad 715, the second-fifth pad 815, and the third-fifth pad 915 may each be one or more, but this is not a limitation.

[0230] For example, the 1-6 pad 716 can be arranged on at least one side of the second partition 1722 so as to face the first woofer-integrated sound-generating device (W3). For example, the 2-6 pad 816 can be arranged on at least one side of the second partition 1722 so as to face the second woofer-integrated sound-generating device (W4). For example, the 3-6 pad 916 can be arranged on at least one side of the second partition 1722 so as to face the third sound-generating device 1600C. The 1-6 pad 716, the 2-6 pad 816, and the 3-6 pad 916 can be composed of one or more pads, but this is not limited to this. The 1-5 pad (715) can be arranged on the side opposite the 1-6 pad 716, and the 1-5 pad (725) can be arranged so as to face the first woofer-integrated sound-generating device (W3). The second-fifth pad 815 can be arranged on the side opposite the second-sixth pad 816, and the second-fifth pad 815 can be arranged to face the second woofer-integrated sound-generating device (W4). The third-fifth pad 915 can be arranged on the side opposite the third-sixth pad 916, and the third-fifth pad 915 can be arranged to face the third sound-generating device 1600C.

[0231] 16G, one or more pads may be arranged on one side of the partition 1750. For example, the 4-5 pad 725 may be arranged on one side of the partition 1750 so as to face the fourth sound-generating device 1600HL, and the 5-5 pad 825 may be arranged so as to face the fifth sound-generating device 1600HR. The 1-6 pad 716 may be arranged on another side of the partition 1750 so as to face the first woofer-integrated sound-generating device (W3), the 3-6 pad (916) may be arranged so as to face the third sound-generating device 1600C, and the 2-6 pad 816 may be arranged so as to face the second woofer-integrated sound-generating device (W4). For example, the 1-5 pad 715 may be arranged on the side opposite the 1-6 pad 716, and the 1-5 pad 715 may be arranged so as to face the first woofer-integrated sound-generating device (W3). The 3-5 pad 915 can be arranged on the side opposite the 3-6 pad 916, and the 3-5 pad 915 can be arranged so as to face the fifth sound-generating device 1600HR. The 2-5 pad 815 can be arranged on the side opposite the 2-6 pad 816, and the 2-5 pad 815 can be arranged so as to face the second woofer-integrated sound-generating device (W4).

[0232] 16H, the first partition 1721 may include one or more vents. For example, the first partition 1721 may include a first vent 701 facing the first woofer-integrated sound-generating device (W3), a second vent 702 facing the second woofer-integrated sound-generating device (W4), and a third vent 703 facing the third sound-generating device 1600C.

[0233] The second partition 1722 may include one or more vents. For example, the second partition 1722 may include a fourth vent 704 directed toward the first woofer-integrated sound-generating device (W3), a fifth vent 705 directed toward the second woofer-integrated sound-generating device (W4), and a sixth vent 706 directed toward the third sound-generating device 1600C.

[0234] Referring to FIG. 16I, first partition 1721 and second partition 1722 may include one or more vents, and partition 1750 may be disposed therebetween. As another example, as shown in FIG. 15G, partition 1750 may be disposed, and first partition 1721 may include one or more vents. Configuring partition 1750 can improve the fixing force of a sound-generating device disposed behind the display panel and reduce sound leakage from the edge or margin of the display panel, thereby improving sound output characteristics. The remaining configuration is the same as or similar to that shown in FIGS. 15I, 16G, and 16H, and therefore detailed description thereof will be omitted.

[0235] The vent portion may have an open structure at the center of the sound-generating device. Without being limited thereto, it may have a "V"-shaped closed structure. An open vent portion at the center of the sound-generating device has the advantage of reducing material costs compared to a closed vent portion. According to an acoustic characteristic experiment, the inventors confirmed that there is little or no difference in acoustic characteristics between a vent portion having an open structure at the center of the sound-generating device and a vent portion having a closed structure. Therefore, by providing one or more vent portions on one side of the first partition 1721 and the second partition 1722, the phenomenon of sound pressure reduction due to standing waves in the sound-generating device can be reduced.

[0236] 16A to 16I, the first woofer-integrated sound-generating device (W3) can be arranged asymmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged asymmetrically with the fifth sound-generating device 1600HR. Referring to FIGS. 16H and 16I, the first vent portion 701 and the fourth vent portion 704 can be arranged asymmetrically, and the second vent portion 702 and the fifth vent portion 705 can be arranged asymmetrically. As another example, the first woofer-integrated sound-generating device (W3) can be arranged symmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged symmetrically with the fifth sound-generating device 1600HR. Referring to Figures 16H and 16I, the first vent portion 701 and the fourth vent portion 704 may be arranged symmetrically, and the second vent portion 702 and the fifth vent portion 705 may be arranged symmetrically.

[0237] Referring to Figures 16F to 16I, each of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, and the 2-3 pad 813 is composed of one pad, but this is not limited to this, and each of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, and the 2-3 pad 813 can be composed of one or more pads.

[0238] As described in Figures 16H and 16I, no vent portion is formed at the end of the display panel, which reduces the pull-in of the display panel when the display panel and the support member are attached, thereby preventing the wave phenomenon.

[0239] 17A to 17I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0240] 17A to 17I, the first sound-generating device 1600L and the second sound-generating device 1600R can be arranged differently from the third sound-generating device 1600C. Descriptions of the same content as those described in Figures 15A to 15I may be omitted or simplified.

[0241] 17A to 17I, the first sound-generating device 1600L and the second sound-generating device 1600R can be arranged asymmetrically with respect to the third sound-generating device 1600C. For example, the first sound-generating device 1600L and the second sound-generating device 1600R can be arranged on the same line. For example, the third sound-generating device 1600C can be arranged on a different line from the first sound-generating device 1600L. For example, the third sound-generating device 1600C can be arranged on a different line from the second sound-generating device 1600R. With this configuration, the first sound generator 1600L is spaced apart from the fourth sound generator 1600HL in the fourth region 4, so that sound from below the display panel can be realized more clearly than with the first sound generator 1600L, and the distance between the first sound generator 1600L and the fourth sound generator 1600HL can realize sound that allows the difference between the sound of the first sound generator 1600L and the sound of the fourth sound generator 1600HL to be distinguished. Furthermore, the second sound generator 1600R is spaced apart from the fifth sound generator 1600HR in the fifth region 5, so that sound from below the display panel can be realized more clearly than with the second sound generator 1600R, and the distance between the second sound generator 1600R and the fifth sound generator 1600HR can realize sound that allows the difference between the sound of the second sound generator 1600R and the sound of the fifth sound generator 1600HR to be distinguished. The first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the fourth sound generator 1600HL, and the fifth sound generator 1600HR can output sounds in the range of 80 Hz to 40 kHz, and the first woofer (W1) and the second woofer (W2) can output sounds below 80 Hz. Therefore, the display device can output 5.1 channel sounds.

[0242] 17F , pads can be arranged on at least one side of the fourth partition 1701 so as to face one or more of the first sound-generating device 1600L and the fourth sound-generating device 1600HL. For example, a 1-3 pad 713 and a 1-4 pad 714 can be arranged on at least one side of the fourth partition 1701 so as to face the first sound-generating device 1600L. A 1-1 pad 711 and a 1-2 pad 712 can be arranged on the side opposite the 1-3 pad 713 and the 1-4 pad 714. For example, a 4-3 pad 723 and a 4-4 pad 724 can be arranged on at least one side of the fourth partition 1701 so as to face the fourth sound-generating device 1600HL. A 4-1 pad 721 and a 4-2 pad 722 can be arranged on the side opposite the 4-3 pad 723 and the 4-4 pad 724. For example, the 3-1 pad 911 and the 3-2 pad 912 may be arranged on at least another side of the fourth partition 1701 so as to face the third sound-generating device 1600C. Only one of the 3-1 pad 911 and the 3-2 pad 912 may be arranged.

[0243] Pads can be arranged on at least one side of the fifth partition 1702 so as to face one or more of the second sound generator 1600R and the fifth sound generator 1600HR. For example, a 2-1 pad 811 and a 2-2 pad 812 can be arranged on at least one side of the fifth partition 1702 so as to face the second sound generator 1600R. A 2-3 pad 813 and a 2-4 pad 814 can be arranged on the side opposite the 2-1 pad 811 and the 2-2 pad 812. Each of the 2-1 pads 811 to 2-4 pads 814 can be composed of two pads, but is not limited to this and can also be composed of one or three or more pads. For example, a 5-1 pad 821 and a 5-2 pad 822 can be arranged on at least one side of the fifth partition 1702 so as to face the fifth sound generator 1600HR. The 5-3 pad 823 and the 5-4 pad 824 may be arranged on the side opposite the 5-1 pad 821 and the 5-2 pad 822. Each of the 5-1 pads 821 to 5-4 pads 824 may consist of two, but may also consist of one or three or more. For example, the 3-3 pad 913 and the 3-4 pad 914 may be arranged on at least another side of the fifth partition 1702 so as to face the third sound-generating device 1600C. Only one of the 3-3 pad 913 and the 3-4 pad 914 may be arranged. The remaining explanation is the same as or similar to the content described with reference to FIGS. 15F to 15I, and therefore will not be repeated here.

[0244] 18A to 18I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0245] 18A to 18I, a first woofer-integrated sound-generating device (W3) can be arranged in the first region 1, and a second woofer-integrated sound-generating device (W4) can be arranged in the second region 2. The first woofer-integrated sound-generating device (W3) and the second woofer-type sound-generating device (W4) can be arranged differently from the third sound-generating device 1600C. Descriptions of the same content as those described in FIGS. 15A to 17I can be omitted or simplified.

[0246] 18A to 18I, the first woofer-integrated sound-generating device (W3) and the second woofer-type sound-generating device (W4) can be arranged asymmetrically with the third sound-generating device 1600C. For example, the first woofer-integrated sound-generating device (W3) and the second woofer-type sound-generating device (W4) can be arranged on the same line. For example, the third sound-generating device 1600C can be arranged on a different line from the first woofer-integrated sound-generating device (W3). For example, the third sound-generating device 1600C can be arranged on a different line from the second woofer-type sound-generating device (W4). In this configuration, the first woofer-type sound-generating device (W3) is spaced apart from the fourth sound-generating device 1600HL in the fourth region 4, so that sound from the underside of the display panel can be realized more clearly than with the first woofer-type sound-generating device (W3), and the distance between the first woofer-type sound-generating device (W3) and the fourth sound-generating device 1600HL can realize sound that allows the difference between the sound of the first woofer-type sound-generating device (W3) and the sound of the fourth sound-generating device 1600HL to be distinguished.Furthermore, the second woofer-type sound-generating device (W4) is spaced apart from the fifth sound-generating device 1600HR in the fifth region 5, so that sound from the underside of the display panel can be realized more clearly than with the second woofer-type sound-generating device (W4), and the distance between the second woofer-type sound-generating device (W4) and the fifth sound-generating device 1600HR can realize sound that allows the difference between the sound of the second woofer-type sound-generating device (W4) and the sound of the fifth sound-generating device 1600HR to be distinguished. The first woofer-integrated sound generating device (W3) and the second woofer-integrated sound generating device (W4) can output sound in the range of 60 Hz to 40 kHz, and the third sound generating device 1600C, the fourth sound generating device 1600HL, and the fifth sound generating device 1600HR can output sound in the range of 80 Hz to 40 kHz. Therefore, the display device can output 5.1 channel sound.

[0247] The first woofer-integrated sound generating device (W3) and the second woofer-integrated sound generating device (W4) are sound generating devices that are integrated with the woofers, which has the advantage that there is no need to configure a separate woofer.

[0248] 18A to 18I, the first woofer-integrated sound-generating device (W3) can be arranged asymmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged asymmetrically with the fifth sound-generating device 1600HR. This configuration can reduce acoustic reinforcement or cancellation caused by interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the fourth sound-generating device 1600HL. In addition to vibrations from the sound source being reproduced, unnecessary acoustic reinforcement or cancellation interference caused by external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of the first woofer-integrated sound-generating device (W3) and the fourth sound-generating device 1600HL can prevent this and reproduce natural sound that is close to the original sound. It reduces acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and the vibrations and standing waves generated by the fifth sound generator 1600HR. In addition to vibrations from the sound source being reproduced, unnecessary acoustic reinforcement or cancellation interference caused by external interference can cause sound distortion and deterioration of sound quality, but the asymmetrical structure of the second woofer-integrated sound generator (W4) and the fifth sound generator 1600HR prevents this and reproduces natural sound close to the original sound.

[0249] Referring to FIGS. 18F and 18G, the first-fifth pad 715 and the fourth-sixth pad 726 may be arranged asymmetrically, and the second-fifth pad 815 and the fifth-sixth pad 826 may be arranged asymmetrically. As another example, the first woofer-integrated sound-generating device (W3) may be arranged symmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) may be arranged symmetrically with the fifth sound-generating device 1600HR. This configuration allows the sound reproduction positions to be aligned on the same line, creating the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the sound position, thereby improving the sense of sound localization. Referring to FIGS. 18F and 18G, the first-fifth pad 715 and the fourth-sixth pad 726 may be arranged symmetrically, and the second-fifth pad 815 and the second-sixth pad 816 may be arranged symmetrically. 18H and 18I, the first vent portion 701 and the fourth vent portion 704 may be arranged asymmetrically, and the second vent portion 702 and the fifth vent portion 705 may be arranged asymmetrically. As another example, the first woofer-integrated sound-generating device (W3) may be arranged symmetrically with the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) may be arranged symmetrically with the fifth sound-generating device 1600HR. Referring to FIGS. 18H and 18I, the first vent portion 701 and the fourth vent portion 704 may be arranged symmetrically, and the second vent portion 702 and the fifth vent portion 705 may be arranged symmetrically.

[0250] 18F to 18I, each of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, the 2-3 pad 813, the 3-1 pad 911, and the 3-3 pad 913 may be configured with one pad. However, without being limited thereto, each of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, the 2-3 pad 813, the 3-1 pad 911, and the 3-3 pad 913 may be configured with two or more pads.

[0251] 19A to 19I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0252] In the following embodiments, the examples shown in FIGS. 19A to 19I will be used as examples, but the same or similar examples can also be applied to the embodiments shown in FIGS. 20A to 27I.

[0253] Referring to FIGS. 19A to 19I, the rear surface of the display panel may include a first region 1 to a fifteenth region 15. The first region 1 to the fifteenth region 15 may have the same area, but are not limited to this. For example, the first region 1 to the fifteenth region 15 may be arranged to have the same spacing or distance, but are not limited to this. The sizes of the first region 1 to the fifteenth region 15 may be adjusted according to the desired sound range. For example, the first region 1, the fourth region 4, and the seventh region 7 may be regions on the left side of the rear surface of the display panel. For example, the second region 2, the fifth region 5, and the eighth region 8 may be regions on the right side of the rear surface of the display panel. For example, the third region 3, the sixth region 6, and the ninth region 9 may be central regions on the rear surface of the display panel. For example, the sixth region 6 may be a region between the fourth region 4 and the fifth region 5. For example, the ninth region 9 may be a region between the seventh region 7 and the eighth region 8. For example, the tenth region 10 may be the region between the first region 1 and the third region 3. For example, the eleventh region 11 may be the region between the second region 2 and the third region 3. For example, the seventh region 7 may be below the first region 1, and the eighth region 8 may be below the second region 2. For example, the tenth region 10, the twelfth region 12, and the fourteenth region 14 may be between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. For example, the eleventh region 11, the thirteenth region 13, and the fifteenth region 15 may be between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The numbers 1 to 15 indicating the regions in the first to fifteenth regions are arbitrary, and the numbers 1 to 15 and the division of the first to fifteenth regions do not limit the contents of the specification. The explanation for this can be applied identically or similarly to FIGS. 20A to 27I.

[0254] At least one sound generating device can be arranged in at least one of the first to fifteenth regions 1600R to 1600R. In the following embodiment, the sound generating device is arranged on the rear surface of the display panel. However, the present invention is not limited to this. The sound generating device can be arranged between the display panel and the support member 300. For example, the sound generating device can be arranged between the rear surface of the display panel and the front surface of the support member 300. For example, the first sound generating device 1600L can be arranged in the first region 1 on the rear surface of the display panel, the fourth sound generating device 1600HL can be arranged in the fourth region 4 on the rear surface of the display panel, and the seventh sound generating device 1600BL can be arranged in the seventh region 7 on the rear surface of the display panel. The second sound generating device 1600R can be arranged in the second region 2 on the rear surface of the display panel, the fifth sound generating device 1600HR can be arranged in the fifth region 5 on the rear surface of the display panel, and the eighth sound generating device 1600BR can be arranged in the eighth region 8 on the rear surface of the display panel. The third sound generator 1600C can be disposed in the third region 3 on the rear surface of the display panel, the sixth sound generator 1600HC can be disposed in the sixth region 6 on the rear surface of the display panel, and the ninth sound generator 1600BC can be disposed in the ninth region 9 on the rear surface of the display panel. The tenth sound generator 1600LC can be disposed in the tenth region 10 on the rear surface of the display panel, and the eleventh sound generator 1600RC can be disposed in the eleventh region 11 on the rear surface of the display panel. The first sound generator 1600L can be the left channel of the display panel, the fourth sound generator 1600HL can be the top left channel of the display panel, the seventh sound generator 1600BL can be the bottom left channel of the display panel, and the tenth sound generator 1600LC can be the left center channel of the display panel. The second sound generating device 1600R may be the right channel of the display panel, the fifth sound generating device 1600HR may be the top right channel of the display panel, and the eighth sound generating device 1600BR may be the bottom right channel of the display panel.The eleventh sound generator 1600RC may be the right center channel of the display panel, the third sound generator 1600C may be the center channel of the display panel, the sixth sound generator 1600HC may be the height center (or top center) channel of the display panel, and the ninth sound generator 1600BC may be the bottom center channel of the display panel.

[0255] For example, but not limited to, the first sound-generating device 1600L can be arranged symmetrically with the fourth sound-generating device 1600HL and / or the seventh sound-generating device 1600BL. For example, but not limited to, the first sound-generating device 1600L can be aligned collinearly with the fourth sound-generating device 1600HL and / or the seventh sound-generating device 1600BL. For example, but not limited to, the second sound-generating device 1600R can be arranged symmetrically with the fifth sound-generating device 1600HR and / or the eighth sound-generating device 1600BR. For example, but not limited to, the second sound-generating device 1600R can be aligned collinearly with the fifth sound-generating device 1600HR and / or the eighth sound-generating device 1600BR. For example, but not limited to, the third sound-generating device 1600C can be arranged symmetrically with the sixth sound-generating device 1600HC and / or the ninth sound-generating device 1600BC. For example, the third sound-generating device 1600C may be aligned on the same line as the sixth sound-generating device 1600HC and / or the ninth sound-generating device 1600BC, but is not limited to this. For example, the tenth sound-generating device 1600LC and the eleventh sound-generating device 1600RC may be arranged symmetrically with at least one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C, but is not limited to this. For example, the tenth sound-generating device 1600LC and the eleventh sound-generating device 1600RC may be aligned on the same line as at least one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C, but is not limited to this. The same or similar explanation can be applied to FIGS. 20A to 27I.

[0256] For example, but not limited to, one of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR can be arranged symmetrically with the sixth sound-generating device 1600HC. For example, but not limited to, one of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR can be aligned on the same line as the sixth sound-generating device 1600HC. For example, but not limited to, one of the first sound-generating device 1600L, the second sound-generating device 1600R, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC can be arranged symmetrically with the third sound-generating device 1600C. For example, but not limited to, one of the first sound-generating device 1600L, the second sound-generating device 1600R, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC can be aligned on the same line as the third sound-generating device 1600C. For example, one of the seventh sound-generating device 1600BL and the eighth sound-generating device 1600BR may be arranged symmetrically with the ninth sound-generating device 1600BC, but is not limited to this. For example, one of the seventh sound-generating device 1600BL and the eighth sound-generating device 1600BR may be aligned on the same line as the ninth sound-generating device 1600BC, but is not limited to this. The same or similar explanations can be applied to Figures 20A to 27I.

[0257] In Figures 19A to 19I, the first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the fourth sound generator 1600HL, the fifth sound generator 1600HR, the sixth sound generator 1600HC, the seventh sound generator 1600BL, the eighth sound generator 1600BR, the ninth sound generator 1600BC, the tenth sound generator 1600LC, and the eleventh sound generator 1600RC may include at least one of the elliptical sound generator, the pair of sound generators, the circular sound generator, the single-type sound generator, the two or more arrays of sound generators, and the film-type sound generator described in Figures 5 to 13. The oval shape may include, but is not limited to, an elliptical shape, a rectangular shape with rounded corners, or a non-circular curved shape having a width different from its height. For example, an oval bobbin may have a ratio of the diameter of its major axis to the diameter of its minor axis of 1.3:1 to 2:1. An oval bobbin may improve high-frequency sound compared to a circular bobbin and may have excellent heat dissipation properties due to less heat generated by vibration. For example, at least one sound-generating device may directly vibrate the display panel to generate sound. The same or similar descriptions may be applied to FIGS. 20A to 27I.

[0258] Referring to FIG. 19B , a partition may be further configured around the sound-generating device. The partition may be an air gap or space through which sound is generated when the display panel 100 is vibrated by the sound-generating device. The partition can separate sounds or channels and prevent or reduce unclear sounds caused by sound interference. The partition may be an air gap or space through which sound is generated and transmitted. The partition may be an enclosure or a baffle, but is not limited to these terms. In the following embodiments, the partition is disposed on a support member as an example. However, the partition may be disposed on the rear surface of the display panel. The partition is disposed on a support member as an example to illustrate the sound-generating device and the partition. For example, when the partition is disposed on the support member, the partition disposed on the display panel can reduce the impact on image quality of the display panel.

[0259] For example, partitions can be disposed between the display panel corresponding to the first to eleventh regions 11 of the display panel and the support member 300. For example, the fourth partition 1713 can be disposed between the first region 1, the fourth region 4, and the seventh region 7 and the third region 3, the sixth region 6, and the ninth region 9. The fourth partition 1713 can separate the sounds or channels generated by the first sound-generating device 1600L, the fourth sound-generating device 1600HL, and the seventh sound-generating device 1600BL from the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC. For example, the fifth partition 1714 can be disposed between the second region 2, the fifth region 5, and the eighth region 8 and the third region 3, the sixth region 6, and the ninth region 9. The fifth partition 1714 can separate the sounds or channels generated by the second sound-generating device 1600R, the fifth sound-generating device 1600HR, and the eighth sound-generating device 1600BR from the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC. Thus, the fourth partition 1713 and the fifth partition 1714 can separate the left and right sounds.

[0260] The first partition 1721 can separate channels above (or above) the display panel from channels below (or below) the display panel. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound generator 1600HL, the fifth sound generator 1600HR, and the sixth sound generator 1600HC, which are located above the display panel, from the sounds or channels generated by the seventh sound generator 1600BL, the eighth sound generator 1600BC, and the ninth sound generator 1600BC, which are located below the display panel. While the tenth sound generator 1600LC and the eleventh sound generator 1600RC are further configured to achieve stereophonic or spatial sound, it is recognized that a partition must be implemented to separate the sounds or channels generated by the tenth sound generator 1600LC from the sounds or channels generated by the seventh sound generator 1600BL, the eighth sound generator 1600BC, and the ninth sound generator 1600BC. It was also recognized that a partition must be implemented to separate the sound or channel generated by the eleventh sound generator 1600RC from the sounds or channels generated by the seventh sound generator 1600BL, the eighth sound generator 1600BC, and the ninth sound generator 1600BC. The fourth partition 1713 and the fifth partition 1714 can separate left and right sounds or left and right channels. The tenth sound generator 1600LC and the eleventh sound generator 1600RC are further configured to achieve stereophonic or spatial sound, but it was recognized that a partition must be implemented to separate the sound or channel generated by the tenth sound generator 1600LC from the sounds or channels generated by the first sound generator 1600L, the fourth sound generator 1600HL, and the seventh sound generator 1600BL. It was also recognized that a partition must be implemented to separate the sounds or channels generated by the eleventh sound generator 1600RC from the sounds or channels generated by the second sound generator 1600R, the fifth sound generator 1600HR, and the eighth sound generator 1600BR.It was recognized that when the first partition 1721 is arranged, it is possible to separate upper and lower sounds or upper and lower channels, but it is not possible to separate the upper and lower sounds or upper and lower channels from the center sound or center channel. It was also recognized that when the fourth partition 1713 and the fifth partition 1714 are arranged, it is possible to separate the left and right sounds or left and right channels, but it is not possible to separate the left and right sounds or left and right channels from the center sound or center channel. Therefore, the inventors of the present specification have realized partitions through several experiments, which will be described below.

[0261] For example, the sixth partition 1711 can be disposed between the first area 1, the fourth area 4, the seventh area 7, and the tenth area 10. For example, the sixth partition 1711 can separate the sounds or channels generated by the first sound-generating device 1600L, the fourth sound-generating device 1600HL, and the seventh sound-generating device 1600BL from the sounds or channels generated by the tenth sound-generating device 1600LC, thereby improving the sound output characteristics. For example, the sixth partition 1711 can separate the sounds or channels generated by the first sound-generating device 1600L, the fourth sound-generating device 1600HL, and the seventh sound-generating device 1600BL from the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC, thereby improving the sound output characteristics. For example, the sixth partition 1711 can separate the left sound or left channel, the left center sound or left center channel, and the center sound or center channel, thereby improving the sound output characteristics.

[0262] For example, the seventh partition 1712 can be disposed between the second region 2, the fifth region 5, and the eighth region 8 and the eleventh region 11. For example, the seventh partition 1712 can separate the sounds or channels generated by the second sound-generating device 1600R, the fifth sound-generating device 1600HR, and the eighth sound-generating device 1600BR from the sounds or channels generated by the eleventh sound-generating device 1600RC, thereby improving the sound output characteristics. For example, the seventh partition 1712 can separate the sounds or channels generated by the second sound-generating device 1600R, the fifth sound-generating device 1600HR, and the eighth sound-generating device 1600BR from the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC, thereby improving the sound output characteristics. For example, the seventh partition 1712 may separate the right sound or channel, the right center sound or channel, and the center sound or channel, thereby improving the sound output characteristics.

[0263] For example, the fourth partition 1713 can be disposed between the third region 3, the sixth region 6, and the ninth region 9 and the tenth region 10. The fourth partition 1713 can separate the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC from the sounds or channels generated by the tenth sound-generating device 1600LC, thereby improving the sound output characteristics. For example, the fifth partition 1714 can be disposed between the third region 3, the fifth region 6, and the ninth region 9 and the eleventh region 11. The fifth partition 1714 can separate the sounds or channels generated by the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC from the sounds or channels generated by the eleventh sound-generating device 1600RC, thereby improving the sound output characteristics. For example, the fourth partition 1713 can separate sounds or channels for the center region from sounds or channels for the left center region, and the fifth partition 1714 can separate sounds or channels for the center region from sounds or channels for the right center region.

[0264] The first partition 1721 can separate the channels on the upper side (Height or Top) of the display panel from the channels on the lower side (Bottom) of the display panel. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound generator 1600HL, the fifth sound generator 1600HR, and the sixth sound generator 1600HC from the sounds or channels generated by the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC. The first partition 1721 can separate the channels on the upper side (Height or Top) of the display panel from the channels in the center of the display panel. For example, the first partition 1721 can separate the sounds or channels generated by the fourth sound generating device 1600HL, the fifth sound generating device 1600HR, and the sixth sound generating device 1600HC from the sounds or channels generated by the first sound generating device 1600L, the second sound generating device 1600R, the third sound generating device 1600C, the tenth sound generating device 1600LC, and the eleventh sound generating device 1600RC.

[0265] The second partition 1722 can separate the center channel of the display panel from the bottom channel of the display panel. For example, the second partition 1722 can separate the sounds or channels generated by the first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the tenth sound generator 1600LC, and the eleventh sound generator 1600RC from the sounds or channels generated by the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC. The third partition 1723 can separate the bottom channel of the display panel from the woofer. For example, the third partition 1723 can be disposed below the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC. For example, the third partition 1723 can separate the sounds or channels generated by the seventh sound generating device 1600BL, the eighth sound generating device 1600BR, and the ninth sound generating device 1600BC from the first woofer (W1) and the second woofer (W2).

[0266] The first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 can be disposed on the support member 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 can be disposed on the front side of the support member 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 can be disposed between the display panel 100 and the support member 300. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 can be arranged between the rear surface of the display panel 100 and the front surface of the support member 300.

[0267] The first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be made of, but are not limited to, one of double-sided tape, double-sided foam pads, single-sided tape, single-sided foam pads, adhesive, and bond. When the partitions are made of double-sided tape or double-sided foam pads, the adhesive strength when attaching the rear surface of the display panel 100 to the upper surface of the support member 300 can be improved. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be made of an elastic material that can be compressed to a certain extent. For example, the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be made of polyurethane, polyolefin, and polyethylene materials, but are not limited to these.

[0268] The fourth sound-generating device 1600HL can be configured in the fourth region 4 and the fifth sound-generating device 1600HR can be configured in the fifth region 5, with no sound-generating device configured in the twelfth region 12. This allows the vibrations of the fourth sound-generating device 1600HL and the fifth sound-generating device 1600HR to be attenuated or absorbed in the twelfth region 12 of the display panel, thereby blocking or reducing the transmission of sound from the fourth region 4 to the fifth region 5, and blocking or reducing the transmission of sound from the fifth region 5 to the fourth region 4. This reduces the deterioration in sound quality caused by interference between sounds generated in the fourth region 4 and the fifth region 5, and has the effect of further improving the acoustic characteristics in the mid- to high-frequency range. For example, the fifth sound-generating device 1600HR can be configured in the fifth region 5 and the sixth sound-generating device 1600HC can be configured in the sixth region 6, with no sound-generating device configured in the thirteenth region 13. As a result, the vibrations of the fifth sound-generating device 1600HR and the sixth sound-generating device 1600HC are attenuated or absorbed in the thirteenth region 13 of the display panel, so that the transmission of sound from the fifth region 5 to the sixth region 6 can be blocked or reduced, and the transmission of sound from the sixth region 6 to the fifth region 5 can be blocked or reduced. Therefore, it is possible to reduce the deterioration in sound quality caused by interference between the sounds generated in the fifth region 5 and the sixth region 6, and it is possible to further improve the acoustic characteristics in the mid-to-high frequency range.

[0269] The seventh sound-generating device 1600BL can be configured in the seventh region 7 and the ninth sound-generating device 1600BC can be configured in the ninth region 9, with no sound-generating device configured in the fourteenth region 14. This allows the vibrations of the seventh sound-generating device 1600BL and the ninth sound-generating device 1600BC to be attenuated or absorbed in the fourteenth region 14 of the display panel, thereby blocking or reducing the transmission of sound from the seventh region 7 to the ninth region 9, and blocking or reducing the transmission of sound from the ninth region 9 to the seventh region 7. This reduces the deterioration in sound quality caused by interference between sounds generated in the seventh region 7 and the ninth region 9, and has the effect of further improving the acoustic characteristics in the mid- to high-frequency range. For example, the eighth sound-generating device 1600BR can be configured in the eighth region 8 and the ninth sound-generating device 1600BC in the ninth region 9, with no sound-generating device configured in the fifteenth region 15. As a result, the vibrations of the eighth sound-generating device 1600BR and the ninth sound-generating device 1600BC are attenuated or absorbed in the fifteenth region 15 of the display panel, so that the transmission of sound from the eighth region 8 to the ninth region 9 can be blocked or reduced, and the transmission of sound from the ninth region 9 to the eighth region 8 can be blocked or reduced. Therefore, it is possible to reduce the deterioration in sound quality caused by interference between the sounds generated in the eighth region 8 and the ninth region 9, and it is possible to further improve the acoustic characteristics in the mid-to-high frequency range.

[0270] 19B, a partition may not be disposed around the periphery of the support member 300. The display panel 100 may be attached to the periphery of the support member 300 using the adhesive member described in FIG. 1B. The adhesive member may be a partition.

[0271] When arranging the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712, the first partition 1721, the second partition 1722, and the third partition 1723 may be arranged before the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712. As another example, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be arranged before the first partition 1721, the second partition 1722, and the third partition 1723, and the order of arrangement does not limit the contents of the specification. In the following embodiment, a first partition 1721, a second partition 1722, and a third partition 1723 are arranged, followed by a fourth partition 1713, a fifth partition 1714, a sixth partition 1711, and a seventh partition 1712, but the present invention is not limited to this. The content of this example can be applied to the following embodiment in the same or similar manner.

[0272] Therefore, the first sound generating device 1600L, the fourth sound generating device 1600HL, and the seventh sound generating device 1600BL can be arranged in the first region 1, the fourth region 4, and the seventh region 7, which are left regions on the rear surface of the display panel 100, to vibrate the left region on the rear surface of the display panel. The second sound generating device 1600R, the fifth sound generating device 1600HR, and the eighth sound generating device 1600BR can be arranged in the second region 2, the fifth region 5, and the eighth region 8, which are right regions on the rear surface of the display panel, to vibrate the right region on the rear surface of the display panel. The third sound generating device 1600C, the sixth sound generating device 1600HC, and the ninth sound generating device 1600BC can be arranged in the third region 3, the sixth region 6, and the ninth region 9, which are central regions on the rear surface of the display panel, to vibrate the central region on the rear surface of the display panel. The tenth sound-generating device 1600LC and the eleventh sound-generating device 1600RC are arranged in the tenth area 10 and the eleventh area 11 of the display panel to vibrate the left area, the center area, and the right area on the rear surface of the display panel. The first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, the sixth sound-generating device 1600HC, the seventh sound-generating device 1600BL, the eighth sound-generating device 1600BR, the ninth sound-generating device 1600BC, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC can receive different vibration signals and be driven independently. For example, the first sound-generating device 1600L, the fourth sound-generating device 1600HL, and the seventh sound-generating device 1600BL can generate sounds by using the left region of the rear surface of the display panel 100 as a diaphragm. The second sound-generating device 1600R, the fifth sound-generating device 1600HR, and the eighth sound-generating device 1600BR can generate sounds by using the right region of the rear surface of the display panel as a diaphragm. The third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC can generate sounds by using the central region of the display panel as a diaphragm.The tenth sound-generating device 1600LC and the eleventh sound-generating device 1600RC can generate sound by using the left, center, and right regions of the rear surface of the display panel as diaphragms. For example, the sixth sound-generating device 1600HC can generate sound above the display panel or upward from the display panel. For example, the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, and the sixth sound-generating device 1600HC can generate sound above the display panel or upward from the display panel, thereby improving sound from above the display panel. For example, the seventh sound-generating device 1600BL, the eighth sound-generating device 1600BR, and the ninth sound-generating device 1600BC can generate sound below the display panel or downward from the display panel, thereby improving sound from below the display panel. A woofer can be placed to improve low-frequency sound. For example, at least one woofer can be further included below the seventh and eighth regions 7 and 8. For example, at least one woofer may be further included below the seventh sound-generating device 1600BL and the eighth sound-generating device 1600BR. For example, the first woofer (W1) may be disposed below the seventh region 7 of the display panel. For example, the first woofer (W1) may be disposed below the seventh sound-generating device 1600BL. For example, the first woofer (W1) may be disposed between the seventh region 7 and the fourteenth region 14. For example, the second woofer (W2) may be disposed below the eighth region 8 of the display panel. For example, the second woofer (W2) may be disposed below the eighth sound-generating device 1600BR. For example, the second woofer (W2) may be disposed between the eighth region 8 and the fifteenth region 15. Therefore, the first woofer (W1) and the second woofer (W2) can output low-frequency sound.The first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the fourth sound generator 1600HL, the fifth sound generator 1600HR, the sixth sound generator 1600HC, the seventh sound generator 1600BL, the eighth sound generator 1600BR, the ninth sound generator 1600BC, the tenth sound generator 1600LC, and the eleventh sound generator 1600RC can output sounds in the range of 80 Hz to 40 kHz. The first woofer (W1) and the second woofer (W2) can output sounds below 80 Hz. Therefore, the display device can output 11.1-channel sounds. Furthermore, since the sound generators are additionally configured above and below the horizontal direction of the display panel compared to the sound generators arranged on the left and right, the left and right sounds and the top and bottom sounds can be improved, providing the user with a sound field similar to that of real sound. For example, by further configuring the tenth sound generator 1600LC and the eleventh sound generator 1600RC, sound can be further improved on the left, right, and center of the display panel. For example, by further configuring the fourth sound generator 1600HL, the fifth sound generator 1600HR, and the sixth sound generator 1600HC, sound can be output from the upper side of the display panel. By further configuring the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC, sound can be output from the lower side of the display panel. This makes it possible to provide a display device that can realize three-dimensional sound including left and right sounds and up and down sounds. Therefore, left and right sounds and up and down sounds can be realized for left and right images and up and down images, and real stereophonic sound (e.g., real sound) including three-dimensional left and right sounds and up and down sounds can be realized for the user, so real sound can be provided, rather than virtual sound. This allows the user to experience real stereophonic or surround sound that is similar to actual sound (e.g., real sound) including stereophonic left and right sounds and up and down sounds, thereby improving the sense of realism.Therefore, even in devices such as movie theaters, private cinemas, and televisions, users can simultaneously experience realistic sounds and images similar to or identical to reality, for example, a realistic AV (Audio Visual) or Dolby sound system. The same or similar explanation can be applied to FIGS. 19B to 27I. As described with reference to FIGS. 6 to 11B, first sound-generating device 1600L, second sound-generating device 1600R, third sound-generating device 1600C, fourth sound-generating device 1600HL, fifth sound-generating device 1600HR, sixth sound-generating device 1600HC, seventh sound-generating device 1600BL, eighth sound-generating device 1600BR, ninth sound-generating device 1600BC, tenth sound-generating device 1600LC, and eleventh sound-generating device 1600RC can be disposed within display panel 100. This reduces the thickness of the sound-generating devices, thereby reducing the thickness of the display device and providing a display device that provides a beautiful impression to the user. As described in Figures 12A and 12B, the first sound generating device 1600L, the second sound generating device 1600R, the third sound generating device 1600C, the fourth sound generating device 1600HL, the fifth sound generating device 1600HR, the sixth sound generating device 1600HC, the seventh sound generating device 1600BL, the eighth sound generating device 1600BR, the ninth sound generating device 1600BC, the tenth sound generating device 1600LC, and the eleventh sound generating device 1600RC can be configured as sound generating devices with improved bass range, and therefore it is possible to provide a display device that can realize left and right sounds and up and down sounds with improved bass range. As described in FIG. 13, the first sound generating device 1600L, the second sound generating device 1600R, the third sound generating device 1600C, the fourth sound generating device 1600HL, the fifth sound generating device 1600HR, the sixth sound generating device 1600HC, the seventh sound generating device 1600BL, the eighth sound generating device 1600BR, the ninth sound generating device 1600BC, the tenth sound generating device 1600LC, and the eleventh sound generating device 1600RC can be configured as film-type sound generating devices, which can reduce the thickness of the sound generating device and provide a display device that can give the user a beautiful appearance.

[0273] Referring to FIG. 19C , a first partition 1721, a second partition 1722, a fourth partition 1713, a fifth partition 1714, a sixth partition 1711, and a seventh partition 1712 are configured, and a partition 1750 may be disposed between the support member 300 and the display panel. For example, the partition 1750 may be disposed at an end or edge of the support member 300. The partition 1750 may occupy the entire four-sided area of ​​the outer periphery of the front surface of the support member 300. As another example, the partition 1750 may be disposed at an end or edge of the rear surface of the display panel. The partition 1750 may occupy the entire four-sided area of ​​the outer periphery of the rear surface of the display panel. The partition 1750 may occupy the entire four-sided area of ​​the outer periphery of the rear surface of the display panel or the front surface of the support member. The partition 1750 may be disposed along the shape of the display panel to prevent the display panel from waviness. For example, if the partition 1750 is an adhesive member for attaching the display panel 100 and the support member 300 described in FIG. 1B, the adhesive member described in FIG. 1B can be omitted. The partition may be an adhesive member. Alternatively, the adhesive member for attaching the display panel 100 and the support member 300 may be formed on the rear surface of the display panel 100 or on the support member 300.

[0274] When arranging the first partition 1721, the second partition 1722, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, the seventh partition 1712, and the partition 1750, the first partition 1721 and the second partition 1722 may be arranged first, and then the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be arranged after the partition 1750 is arranged. As another example, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712 may be arranged first, and then the first partition 1721 and the second partition 1722 may be arranged before the partition 1750 is arranged. The order of arrangement does not limit the contents of the specification. The partition 1750 may be arranged first in the vertical direction of the support member 300 and then in the horizontal direction. As another example, partition 1750 may be first arranged in the horizontal direction of support member 300 and then arranged in the vertical direction, and the order of arrangement is not a limitation of the contents of the specification. In the following embodiment, the first partition 1721, second partition 1722, and / or third partition 1723 are arranged first, and then partition 1750 is arranged, followed by fourth partition 1713, fifth partition 1714, sixth partition 1711, and seventh partition 1712, but the present invention is not limited to this example. The content of this description may be applied equally or similarly to the following embodiments.

[0275] 19D and 19E, the shapes of the first partition 1721, the second partition 1722, and the third partition 1723 can be configured differently. The first partition 1721, the second partition 1722, and the third partition 1723 can be configured to have a shape different from the shape of the display panel. For example, the first partition 1721, the second partition 1722, and the third partition 1723 can be non-flat or non-linear. For example, the first partition 1721, the second partition 1722, and the third partition 1723 can have a sawtooth shape, a triangular shape, or a rounded triangular shape. For example, the sawtooth of the first partition 1721, the second partition 1722, and the third partition 1723 can be oriented to face the sound-generating device. For example, if the first partition 1721, the second partition 1722, and the third partition 1723 are triangular, the tips of the triangles can be arranged to face the sound-generating devices. For example, if the first partition 1721, the second partition 1722, and the third partition 1723 are triangular with rounded tips, the tips of the rounded triangles can be arranged to face the sound-generating devices. For example, referring to FIG. 19D , if the first partition 1721 is triangular with rounded tips, the tips of the rounded triangles can be configured to face the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, and the sixth sound-generating device 1600HC. For example, if the second partition 1722 has a rounded triangular shape, the tip of the rounded triangle can be configured to face the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. For example, if the third partition 1723 has a rounded triangular shape, the tip of the rounded triangle can be configured to face one or more of the seventh sound-generating device 1600BL, the eighth sound-generating device 1600BR, and the ninth sound-generating device 1600BC.Therefore, by configuring the shape of the partition so that it faces at least one sound-generating device, it is possible to control peaks and dips caused by standing waves of the sound-generating device and reduce wave phenomena on the display panel. Furthermore, by changing the shape of the partition, it is possible to solve acoustic interference such as diffuse reflection from the sound-generating device.

[0276] If the partitions are not flat or linear, they can disperse standing waves, for example, sawtooth, triangular, and rounded triangular shapes, which can disperse standing waves in multiple directions, thereby improving the acoustic output characteristics.

[0277] 19E , one of the first partition 1721, the second partition 1722, and the third partition 1723 may be configured with two partitions. Without being limited to this, one of the first partition 1721 and the second partition 1722 may be configured with two partitions. For example, the first partition 1721 may include a 1-1 partition 1721a and a 1-2 partition 1721b, and may be configured with a triangular or rounded triangular shape. The tip of the triangle or rounded triangular shape of the 1-1 partition 1721a may be configured to face one or more of the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, and the sixth sound-generating device 1600HC. The tip of the triangle or rounded triangle shape of the 1-2 partition 1721b can be configured to face one or more of the first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the tenth sound generator 1600LC, and the eleventh sound generator 1600RC. For example, the second partition 1722 can include the 2-1 partition 1722a and the 2-2 partition 1722b and can be configured with a triangle or rounded triangle shape. The tip of the triangle or rounded triangle shape of the 2-1 partition 1722a can be configured to face one or more of the first sound generator 1600L, the second sound generator 1600R, the third sound generator 1600C, the tenth sound generator 1600LC, and the eleventh sound generator 1600RC. The tip of the triangle or rounded triangle shape of the 2-2 partition 1722b can be configured to face one or more of the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC. The tip of the triangle or rounded triangle shape of the third partition 1723 can be configured to face one or more of the seventh sound generator 1600BL, the eighth sound generator 1600BR, and the ninth sound generator 1600BC. This makes it possible to control peak and dip phenomena caused by standing waves of the sound generators and reduce wave phenomena in the display panel.

[0278] 19F to 19I, pads may be arranged on at least one side of the sixth partition 1711 so as to face one or more of the first sound-generating device 1600L, the fourth sound-generating device 1600HL, and the seventh sound-generating device 1600BL. For example, a 1-3 pad 713 may be arranged on at least one side of the sixth partition 1711 so as to face the first sound-generating device 1600L. A 1-1 pad 711 may be arranged on the side opposite the 1-3 pad 713. The 1-1 pad 711 and the 1-3 pad 713 may each be formed as a single pad. However, this is not limiting, and one or more of the 1-1 pad 711 and the 1-3 pad 713 may also be formed as two or more pads. For example, a 4-3 pad 723 may be arranged on at least one side of the sixth partition 1711 so as to face the fourth sound-generating device 1600HL. The 4-1 pad 721 may be arranged on the side opposite the 4-3 pad 723. The 4-1 pad 721 and the 4-3 pad 723 may be configured as a single pad, but this is not limited to this and one or more of the 4-1 pad 721 and the 4-3 pad 723 may be configured as two or more. For example, the 7-3 pad 733 may be arranged on at least one side of the sixth partition 1711 so as to face the seventh sound-generating device 1600BL. The 7-1 pad 731 may be arranged on the side opposite the 7-3 pad 733. The 7-1 pad 731 and the 7-3 pad 733 may be configured as a single pad, but this is not limited to this and one or more of the 7-1 pad 731 and the 7-3 pad 733 may be configured as two or more.

[0279] A pad can be arranged on at least one other side of the sixth partition 1711 so as to face the tenth sound-generating device 1600LC. For example, a 10-1 pad 741 can be arranged on at least one other side of the sixth partition 1711 so as to face the tenth sound-generating device 1600LC. The 10-1 pad 741 can be configured as one pad, but is not limited to this and can be configured as two or more pads.

[0280] Pads may be arranged on at least one side of the seventh partition 1712 so as to face one or more of the second sound-generating device 1600R, the fifth sound-generating device 1600HR, and the eighth sound-generating device 1600BR. For example, a 2-1 pad 811 may be arranged on at least one side of the seventh partition 1712 so as to face the second sound-generating device 1600R. A 2-3 pad 813 may be arranged on the side opposite the 2-1 pad 811. The 2-1 pad 811 and the 2-3 pad 813 may each be formed as a single pad. However, this is not limiting, and one or more of the 2-1 pad 811 and the 2-3 pad 813 may also be formed as two or more pads. For example, a 5-1 pad 821 may be arranged on at least one side of the seventh partition 1712 so as to face the fifth sound-generating device 1600HR. A 5-3 pad 823 may be arranged on the side opposite the 5-1 pad 821. The 5-1 pad 821 and the 5-3 pad 823 may each be formed as a single pad, but are not limited to this and may comprise two or more of one or more of the 5-1 pad 821 and the 5-3 pad 823. For example, the 8-1 pad 831 may be arranged on at least one side of the seventh partition 1712 so as to face the eighth sound-generating device 1600BR. The 8-3 pad 833 may be arranged on the side opposite the 8-1 pad 831.

[0281] A pad may be arranged on at least one other side of the seventh partition 1712 so as to face the eleventh sound-generating device 1600RC. For example, an 11-3 pad 843 may be arranged on at least one other side of the seventh partition 1712 so as to face one or more of the eleventh sound-generating devices 1600RC. The 11-3 pad 843 may consist of one pad, but is not limited to this and may consist of two or more pads.

[0282] Pads can be arranged on at least one side of the fourth partition 1713 and at least one side of the fifth partition 1714 so as to face one or more of the third sound-generating device 1600C, the sixth sound-generating device 1600HC, and the ninth sound-generating device 1600BC. For example, a 3-1 pad 911 can be arranged on at least one side of the sixth partition 1711 so as to face the third sound-generating device 1600C. For example, a 3-3 pad 913 can be arranged on at least one side of the fifth partition 1714 so as to face the third sound-generating device 1600C. The 3-1 pad 911 can be arranged facing the 3-3 pad 913. For example, the 3-3 pad 913 can be arranged on the side of the fifth partition 1714 facing the 3-1 pad 911. Each of the 3-1 pad 911 and the 3-3 pad 913 may be formed of one pad. However, this is not limiting, and one of the 3-1 pad 911 and the 3-3 pad 913 may be formed of two or more pads. For example, the 6-1 pad 921 may be arranged on at least one side of the fourth partition 1713 so as to face the sixth sound-generating device 1600HC. For example, the 6-3 pad 923 may be arranged on at least one side of the fifth partition 1714 so as to face the sixth sound-generating device 1600HC. The 6-1 pad 921 may be arranged facing the 6-3 pad 923. For example, the 6-3 pad 923 may be arranged on the side of the fifth partition 1714 facing the 6-1 pad 921. Each of the 6-1 pad 921 and the 6-3 pad 923 may be formed of one pad, but is not limited to this. One of the 6-1 pad 921 and the 6-3 pad 923 may also be formed of two or more pads. For example, the 9-1 pad 931 may be arranged on at least one side of the fourth partition 1713 so as to face the 9th sound-generating device 1600BC. For example, the 9-3 pad 933 may be arranged on at least one side of the fifth partition 1714 so as to face the 9th sound-generating device 1600BC. The 9-1 pad 931 may be arranged facing the 9-3 pad 933.For example, the 9-3 pad 933 can be disposed on the side of the fifth partition 1714 opposite the 9-1 pad 931. The 9-1 pad 931 and the 9-3 pad 933 can be configured as a single pad, but this is not limited to this, and one or more of the 9-1 pad 931 and the 9-3 pad 933 can also be configured as two or more pads.

[0283] For example, the 10-3 pad 743 can be arranged on at least one other side of the fourth partition 1713 so as to face the tenth sound-generating device 1600LC. For example, the 11-1 pad 841 can be arranged on at least one other side of the seventh partition 1712 so as to face the eleventh sound-generating device 1600RC. The 10-3 pad 743 and the 11-1 pad 841 can be configured as a single pad, but this is not limiting, and one or more of the 10-3 pad 743 and the 11-1 pad 841 can also be configured as two or more pads.

[0284] Pads may be arranged on at least one side of the first partition 1721 so as to face one or more of the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, and the sixth sound-generating device 1600HC. For example, a 4-6 pad 726 may be arranged on at least one side of the first partition 1721 so as to face the fourth sound-generating device 1600HL. A 4-5 pad 725 may be arranged on the side opposite the 4-6 pad 726, and the 4-5 pad 725 may be arranged so as to face the fourth sound-generating device 1600HL. The 4-5 pad 725 and the 4-6 pad 726 may each be formed as a single pad, but are not limited thereto. One or more of the 4-5 pad 725 and the 4-6 pad 726 may also be formed as two or more pads.

[0285] For example, the 5-6 pad 826 can be arranged on at least one side of the first partition 1721 so as to face the fifth sound-generating device 1600HR. The 5-5 pad 825 can be arranged on the side opposite the 5-6 pad 826, and the 5-5 pad 825 can be arranged so as to face the fifth sound-generating device 1600HR. The 5-5 pad 825 and the 5-6 pad 826 can be configured as a single pad, but are not limited to this, and one or more of the 5-5 pad 825 and the 5-6 pad 826 can also be configured as two or more pads.

[0286] For example, a 6-6 pad 926 may be arranged on at least one side of the first partition 1721 so as to face the sixth sound-generating device 1600HC. A 6-5 pad 925 may be arranged on the side opposite the 6-6 pad 926, and the 6-5 pad 925 may be arranged so as to face the sixth sound-generating device 1600HC. The 6-5 pad 925 and the 6-6 pad 926 may each be formed as a single pad, but are not limited to this. Two or more pads may be used for one or more of the 6-5 pad 925 and the 6-6 pad 926.

[0287] For example, pads may be arranged on at least one other side of the first partition 1721 to face one or more of the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. For example, a 1-5 pad 715 may be arranged on at least one other side of the first partition 1721 to face the first sound-generating device 1600L. For example, a 2-5 pad 815 may be arranged on at least one other side of the first partition 1721 to face the second sound-generating device 1600R. For example, a 3-5 pad 915 may be arranged on at least one other side of the first partition 1721 to face the third sound-generating device 1600C. For example, a 10-5 pad 745 may be arranged on at least one other side of the first partition 1721 so as to face the tenth sound-generating device 1600LC. For example, an 11-5 pad 845 may be arranged on at least one side of the first partition 1721 so as to face the eleventh sound-generating device 1600RC. The 1-5 pad 715, the 2-5 pad 815, the 3-5 pad 915, the 10-5 pad 745, and the 11-5 pad 845 may each be formed as a single pad, but is not limited to this. One or more of the 1-5 pad 715, the 2-5 pad 815, the 3-5 pad 915, the 10-5 pad 745, and the 11-5 pad 845 may also be formed as two or more pads.

[0288] For example, pads can be arranged on at least one side of the second partition 1722 so as to face one or more of the first sound-generating device 1600L, the second sound-generating device 1600R, the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. For example, the 1-6 pad 716 can be arranged on at least one side of the second partition 1722 so as to face the first sound-generating device 1600L. For example, the 2-6 pad 816 can be arranged on at least one side of the second partition 1722 so as to face the second sound-generating device 1600R. For example, the 3-6 pad 916 can be arranged on at least one side of the second partition 1722 so as to face the third sound-generating device 1600C. For example, the 10-6 pad 746 can be arranged on at least one side of the second partition 1722 so as to face the tenth sound-generating device 1600LC. For example, the 11-6 pad 846 can be arranged on at least one side of the second partition 1722 so as to face the eleventh sound-generating device 1600RC. The 1-6 pad 716, the 2-6 pad 816, the 3-6 pad 916, the 10-6 pad 746, and the 11-6 pad 846 can each be formed as a single pad, but this is not limiting, and one or more of the 1-6 pad 716, the 2-6 pad 816, the 3-6 pad 916, the 10-6 pad 746, and the 11-6 pad 846 can also be formed as two or more pads.

[0289] The 1-5 pad 715 can be positioned opposite the 1-6 pad 716. For example, the 1-6 pad 716 can be positioned on the side of the second partition 1722 opposite the 1-5 pad 715. The 2-5 pad 815 can be positioned opposite the 2-6 pad 816. For example, the 2-6 pad 816 can be positioned on the side of the second partition 1722 opposite the 2-5 pad 815. The 3-5 pad 915 can be positioned opposite the 3-6 pad 916. For example, the 3-6 pad 916 can be positioned on the side of the second partition 1722 opposite the 3-5 pad 915. The 10-5 pad 745 can be positioned opposite the 10-6 pad 746. For example, the 10-6 pad 746 can be positioned on the side of the second partition 1722 opposite the 10-5 pad 745. The 11-5 pad 845 can be disposed opposite the 11-6 pad 846. For example, the 11-6 pad 846 can be disposed on the side of the second partition 1722 opposite the 11-5 pad 845.

[0290] For example, pads can be arranged on at least one other side of the second partition 1722 to face one or more of the seventh sound-generating device 1600BL, the eighth sound-generating device 1600BR, and the ninth sound-generating device 1600BC. For example, a 7-5 pad 735 can be arranged on at least one other side of the second partition 1722 to face the seventh sound-generating device 1600BL. For example, an 8-5 pad 835 can be arranged on at least one other side of the second partition 1722 to face the eighth sound-generating device 1600BR. For example, a 9-5 pad 935 can be arranged on at least one other side of the second partition 1722 to face the ninth sound-generating device 1600BC. The 7-5 pad 735, the 8-5 pad 835, and the 9-5 pad 935 may be composed of one pad, but this is not limited to this, and one or more of the 7-5 pad 735, the 8-5 pad 835, and the 9-5 pad 935 may also be composed of two or more pads.

[0291] For example, pads can be arranged on at least one side of the third partition 1723 so as to face one or more of the seventh sound-generating device 1600BL, the eighth sound-generating device 1600BR, and the ninth sound-generating device 1600BC. For example, a 7-6 pad 736 can be arranged on at least one side of the third partition 1723 so as to face the seventh sound-generating device 1600BL. For example, an 8-6 pad 836 can be arranged on at least one side of the third partition 1723 so as to face the eighth sound-generating device 1600BR. For example, a 9-6 pad 936 can be arranged on at least one side of the third partition 1723 so as to face the ninth sound-generating device 1600BC. The 7-6 pad 736, the 8-6 pad 836, and the 9-6 pad 936 may each be formed as a single pad. However, one or more of the 7-6 pad 736, the 8-6 pad 836, and the 9-6 pad 936 may each be formed as two or more pads. In the illustrated embodiment, the 1-1 pad 711 and the 1-3 pad 713 are larger than the 1-5 pad 715 and the 1-6 pad 716, respectively. However, the size of the pads is not intended to limit the scope of the present specification. For example, the 1-1 pad 711 and the 1-3 pad 713 may be smaller or the same as the 1-5 pad 715 and the 1-6 pad 716, respectively. The same or similar pad sizes may also be used for the other pads. In FIG. 19F, a partition may not be disposed around the periphery of the support member 300. The display panel 100 can be attached to the periphery of the support member 300 by the adhesive member described in FIG. 1B, and the adhesive member can be a partition.

[0292] 19G, the partition 1750 may include a first partition 1721, a second partition 1722, a fourth partition 1713, a fifth partition 1714, a sixth partition 1711, a seventh partition 1712, and a partition 1750. For example, one or more pads may be included on one side of the partition 1750. On one side of the partition 1750, a 4-5 pad 725 may be positioned to face the fourth sound-generating device 1600HL, a 5-5 pad 825 may be positioned to face the fifth sound-generating device 1600HR, and a 6-5 pad 925 may be positioned to face the sixth sound-generating device 1600HC. On the other side of the partition 1750, the 7-6 pad 736 can be arranged to face the seventh sound-generating device 1600BL, the 8-6 pad 836 can be arranged to face the eighth sound-generating device 1600BR, and the 9-6 pad 936 can be arranged to face the ninth sound-generating device 1600BC. Configuring the partition 1750 can improve the fixing force of the sound-generating devices arranged behind the display panel and reduce sound leakage from the edge or margin of the display panel, thereby improving the sound output characteristics. The remaining configuration is the same or similar to that described with reference to FIG. 19F, so detailed description will be omitted.

[0293] For example, if the partition 1750 is an adhesive member for attaching the display panel 100 and the support member 300 as described in Fig. 1B, the adhesive member described in Fig. 1B can be omitted. However, the adhesive member for attaching the display panel 100 and the support member 300 can be formed on the rear surface of the display panel 100 or on the support member 300.

[0294] 19H and 19I, the first partition 1721 and the second partition 1722 may include vent portions. The remaining configuration is the same as or similar to that of FIG. 19F, and therefore, detailed description thereof will be omitted.

[0295] 19H, the first partition 1721 may include one or more vents. For example, the first partition 1721 may include a first vent 701 directed toward the first sound-generating device 1600L and a seventh vent 707 directed toward the tenth sound-generating device 1600LC. The first partition 1721 may include a second vent 702 directed toward the second sound-generating device 1600R and an eighth vent 708 directed toward the eleventh sound-generating device 1600RC. The first partition 1721 may include a third vent 703 directed toward the third sound-generating device 1600C. Furthermore, the reduction in sound pressure due to standing waves in the fourth sound-generating device 1600HL, the fifth sound-generating device 1600HR, and the sixth sound-generating device 1600HC can be reduced by the fourth-fifth pad 725, the fifth-fifth pad 825, and the sixth-fifth pad 925.

[0296] The second partition 1722 may include one or more vents. For example, the second partition 1722 may include a fourth vent 704 directed toward the first sound-generating device 1600L and a ninth vent 709 directed toward the tenth sound-generating device 1600LC. The second partition 1722 may include a fifth vent 705 directed toward the second sound-generating device 1600R and a tenth vent 710 directed toward the eleventh sound-generating device 1600RC. The second partition 1722 may include a sixth vent 706 directed toward the third sound-generating device 1600C.

[0297] The third partition 1723 may not include a vent, but may include one or more vents, as shown in Figure 20H.

[0298] The vent portion may have an open structure at the center of the sound-generating device. Without being limited thereto, it may have a "V"-shaped closed structure. Having an open structure at the center of the sound-generating device has the advantage of reducing material costs compared to having a closed structure. According to an acoustic property experiment, the inventors confirmed that there is little or no difference in acoustic properties between the open and closed vent portions at the center of the sound-generating device. Therefore, by including one or more vent portions in the first partition 1721 and the second partition 1722, the phenomenon of sound pressure reduction due to standing waves in the sound-generating device can be reduced.

[0299] Referring to FIG. 19I, first partition 1721 and second partition 1722 may include one or more vents, and partition 1750 may be provided. Third partition 1723 may not include a vent. Alternatively, third partition 1723 may include one or more vents, as shown in FIG. 20I. By providing partition 1750, the fixing strength of a sound-generating device disposed behind the display panel can be improved, and sound leakage from the edge or margin of the display panel can be reduced, thereby improving sound output characteristics. The remaining configuration is the same as or similar to that of FIG. 19H, and therefore detailed description thereof will be omitted.

[0300] As described in Figures 19H and 19I, the end of the support member 300 does not have a vent portion, so that the retraction of the display panel when attaching the display panel to the support member 300 can be reduced, thereby preventing the wave phenomenon.

[0301] 20A to 20I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0302] 20A to 20I, a first woofer-integrated sound-generating device (W3) can be arranged in the seventh region 7, and a second woofer-integrated sound-generating device (W4) can be arranged in the eighth region 8. Descriptions of the same content as those described in FIGS. 15A to 15I and / or 18A to 19I can be omitted or simplified.

[0303] The first woofer-integrated sound generating device (W3) and the second woofer-integrated sound generating device (W4) are sound generating devices configured integrally with woofers, and therefore have the advantage of eliminating the need to configure separate woofers.

[0304] 20A to 20I, the first woofer-integrated sound-generating device W3 may be disposed symmetrically with one of the first sound-generating device 1600L and the fourth sound-generating device 1600HL. For example, the first woofer-integrated sound-generating device W3 may be disposed on the same line as one of the first sound-generating device 1600L and the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device W4 may be disposed symmetrically with one of the second sound-generating device 1600R and the fifth sound-generating device 1600HR. For example, the second woofer-integrated sound-generating device W4 may be disposed on the same line as one of the second sound-generating device 1600R and the fifth sound-generating device 1600HR. This configuration allows the sound reproduction positions to be aligned on the same line, providing the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the sound position, thereby improving the sense of sound localization. 20F and 20G, the 7-5 pad 735 and the 7-6 pad 736 may be arranged symmetrically with one of the 1-5 pad 715, the 1-6 pad 716, the 4-5 pad 725, and the 4-6 pad 726. The 8-5 pad 835 and the 8-6 pad 836 may be arranged symmetrically with one of the 2-5 pad 815, the 2-6 pad 816, the 5-5 pad 825, and the 5-6 pad 826. Referring to FIGS. 20H and 20I, the 11th vent portion 801 may be arranged symmetrically with one of the 1st vent portion 701 and the 4th vent portion 704, and the 12th vent portion 802 may be arranged symmetrically with one of the 2nd vent portion 702 and the 5th vent portion 705.

[0305] As another example, the first woofer-integrated sound-generating device (W3) can be arranged asymmetrically with one of the first sound-generating device 1600L or the fourth sound-generating device 1600HL. The second woofer-integrated sound-generating device (W4) can be arranged asymmetrically with one of the second sound-generating device 1600R or the fifth sound-generating device 1600HR. In this configuration, acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the first sound-generating device 1600L or the fourth sound-generating device 1600HL can be reduced. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of one of the first sound generators 1600L and 1600HL and the first woofer-integrated sound generator (W3) prevents this, allowing for the reproduction of natural sound close to the original sound. This reduces acoustic reinforcement or destructive interference due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and the vibrations and standing waves generated by the second sound generator 1600R or the fifth sound generator 1600HR. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of one of the second sound generators 1600R and 1600HR and the second woofer-integrated sound generator (W4) prevents this, allowing for the reproduction of natural sound close to the original sound. 20F and 20G, the 7-5 pad 735 and the 7-6 pad 736 can be arranged asymmetrically with one of the 1-5 pad 715, the 1-6 pad 716, the 4-5 pad 725, and the 4-6 pad 726. The 8-5 pad 835 and the 8-6 pad 836 can be arranged asymmetrically with one of the 2-5 pad 815, the 2-6 pad 816, the 5-5 pad 825, and the 5-6 pad 826.20H and 20I, the eleventh vent portion 801 may be disposed asymmetrically with one of the first vent portion 701 and the fourth vent portion 704, and the twelfth vent portion 802 may be disposed asymmetrically with one of the second vent portion 702 and the fifth vent portion 705. Referring to FIGS. 20F to 20I, the pad may be formed of one piece, but is not limited thereto, and one of the pads may be formed of two or more pieces.

[0306] 20A to 20I, the first woofer-integrated sound-generating device (W3) can be arranged symmetrically with the ninth sound-generating device 1600BC. For example, the first woofer-integrated sound-generating device (W3) can be arranged on the same line as the ninth sound-generating device 1600BC. The second woofer-integrated sound-generating device (W4) can be arranged symmetrically with the ninth sound-generating device 1600BC. For example, the second woofer-integrated sound-generating device (W4) can be arranged on the same line as the ninth sound-generating device 1600BC. With this configuration, the sound reproduction positions can be aligned on the same line, which gives the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the position of the sound, thereby improving the sense of sound localization. 20F and 20G, the 7-1 pad 731 and the 7-3 pad 733 can be arranged symmetrically with one of the 9-1 pad 931 and the 9-3 pad 933. The 8-1 pad 831 and the 8-3 pad 833 can be arranged symmetrically with one of the 9-1 pad 931 and the 9-3 pad 933.

[0307] As another example, the first woofer-integrated sound-generating device (W3) can be positioned asymmetrically relative to the ninth sound-generating device 1600BC. The second woofer-integrated sound-generating device (W4) can be positioned asymmetrically relative to the ninth sound-generating device 1600BC. This configuration can reduce acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the ninth sound-generating device 1600BC. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or cancellation due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of the first woofer-integrated sound-generating device (W3) and the ninth sound-generating device 1600BC can prevent this and reproduce natural sound that is close to the original sound. This reduces acoustic reinforcement or cancellation caused by vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound-generating device (W4) and the vibrations and standing waves generated by the ninth sound-generating device 1600BC. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or cancellation due to external interference can cause sound distortion and deterioration in sound quality. However, the asymmetrical structure of the first woofer-integrated sound-generating device (W3) and the ninth sound-generating device 1600BC prevents this and reproduces natural sound that is closer to the original sound. Referring to Figures 20F and 20G, the 7-1 pad 731 and the 7-3 pad 733 can be positioned asymmetrically with one of the 9-1 pad 931 and the 9-3 pad 933. The 8-1 pad 831 and the 8-3 pad 833 can be positioned asymmetrically with one of the 9-1 pad 931 and the 9-3 pad 933.

Therefore, the display device can output 11.1 channel sound.

[0309] 20F , a pad may be arranged on at least one side of one of the first partition 1721, the second partition 1722, the third partition 1723, the fourth partition 1713, the fifth partition 1714, the sixth partition 1711, and the seventh partition 1712, so as to face the sound-generating device. For example, a 7-3 pad 733 may be arranged on at least one side of the sixth partition 1711 so as to face the first woofer-integrated sound-generating device (W3). A 7-1 pad 731 may be arranged on the side opposite the 7-3 pad 733.

Configuring the partition 1750 can improve the fixing strength of the sound-generating devices arranged behind the display panel and reduce sound leakage from the edge or margin of the display panel, thereby improving the sound output characteristics. The remaining configuration is the same as or similar to that of FIG. 20F, and therefore will not be described in detail.

[0312] 20H , one of the first partition 1721, the second partition 1722, and the third partition 1723 may include one or more vent portions.

The second partition 1722 may include a fifth vent 705 directed toward the second sound-generating device 1600R and a tenth vent 710 directed toward the eleventh sound-generating device 1600RC. The second partition 1722 may include a sixth vent 706 directed toward the third sound-generating device 1600C.

[0315] Referring to FIG. 20I, one of the first partition 1721, the second partition 1722, and the third partition 1723 may include one or more vents, forming a partition 1750.

As another example, as shown in FIG. 19I, the third partition 1723 may not include one or more vents. The remaining configuration is the same as or similar to that of FIG. 20H, and therefore a detailed description thereof will be omitted.

[0316] 21A to 21I are diagrams showing examples of a sound generating device and a partition according to an embodiment of the present specification.

[0317] 21A to 21I, a first woofer-integrated sound-generating device (W3) can be arranged in the first area 1, and a second woofer-integrated sound-generating device (W4) can be arranged in the second area 2. Descriptions of the same content as those described in Figures 15A to 15I and / or 20A to 20I may be omitted or simplified.

[0318] 21A to 21I, the first woofer-integrated sound-generating device W3 can be arranged symmetrically with one of the fourth sound-generating device 1600HL and the seventh sound-generating device 1600BL. The first woofer-integrated sound-generating device W3 can be arranged on the same line as one of the fourth sound-generating device 1600HL and the seventh sound-generating device 1600BL. The second woofer-integrated sound-generating device W4 can be arranged symmetrically with one of the fifth sound-generating device 1600HR and the eighth sound-generating device 1600BR. The second woofer-integrated sound-generating device W4 can be arranged on the same line as one of the fifth sound-generating device 1600HR and the eighth sound-generating device 1600BR. This configuration allows the sound reproduction positions to be aligned on the same line, providing the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the sound position, thereby improving the sense of sound localization. 21F and 21G, the 1-5 pad 715 and the 1-6 pad 716 can be arranged symmetrically with one of the 4-5 pad 725, the 4-6 pad 726, the 7-5 pad 735, and the 7-6 pad 736, and the 2-5 pad 815 and the 2-6 pad 816 can be arranged symmetrically with one of the 5-5 pad 825, the 5-6 pad 826, the 8-5 pad 835, and the 8-6 pad 836.

The second woofer-integrated sound-generating device (W4) can be arranged asymmetrically with one of the fifth sound-generating device 1600HR and the eighth sound-generating device 1600BR. In this configuration, acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the fourth sound-generating device 1600HL or the seventh sound-generating device 1600BL can be reduced. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of one of the fourth sound generator 1600HL or seventh sound generator 1600BL and the first woofer-integrated sound generator (W3) prevents this, allowing for the reproduction of natural sound close to the original. It also reduces acoustic reinforcement or destructive interference due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and those generated by the fifth sound generator 1600HR or eighth sound generator 1600BR. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and degradation of sound quality. However, the asymmetric structure of one of the fifth sound generator 1600HR or eighth sound generator 1600BR and the second woofer-integrated sound generator (W4) prevents this, allowing for the reproduction of natural sound close to the original. Referring to Figures 21F and 21G, the 1-5 pad 715 and the 1-6 pad 716 can be arranged asymmetrically with one of the 4-5 pad 725, the 4-6 pad 726, the 7-5 pad 735, and the 7-6 pad 736, and the 2-5 pad 815 and the 2-6 pad 816 can be arranged asymmetrically with one of the 5-5 pad 825, the 5-6 pad 826, the 8-5 pad 835, and the 8-6 pad 836.21H and 21I, one of the first vent portion 701 and the fourth vent portion 704 may be disposed asymmetrically with the eleventh vent portion 801, and one of the second vent portion 702 and the fifth vent portion 705 may be disposed asymmetrically with the twelfth vent portion 802. Referring to FIGS. 21F to 21I, the pad may be formed of one piece, but is not limited thereto, and one of the pads may be formed of two or more pieces.

[0320] 21A to 21I, the first woofer-integrated sound-generating device (W3) may be arranged symmetrically with one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. For example, the first woofer-integrated sound-generating device (W3) may be arranged on the same line as one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. The second woofer-integrated sound-generating device (W4) may be arranged symmetrically with one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. For example, the second woofer-integrated sound-generating device (W4) can be arranged on the same line as one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. This arrangement allows the sound reproduction positions to be aligned on the same line, providing the effect of sound being reproduced at the same position compared to an asymmetrical arrangement. This improves the perception of the sound position, thereby improving the sense of sound localization. Referring to FIGS. 21F and 21G, one of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, and the 2-3 pad 813 can be arranged symmetrically with one of the 3-1 pad 911, the 3-3 pad 913, the 10-1 pad 741, the 10-3 pad 743, the 11-1 pad 841, and the 11-3 pad 843.

[0321] As another example, the first woofer-integrated sound-generating device (W3) can be positioned asymmetrically with one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. The second woofer-integrated sound-generating device (W4) can be positioned asymmetrically with one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC. This configuration can reduce acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the first woofer-integrated sound-generating device (W3) and the vibrations and standing waves generated by the third sound-generating device 1600C, the tenth sound-generating device 1600LC, or the eleventh sound-generating device 1600RC. In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and deterioration in sound quality, but the asymmetric structure of one of the third sound generator 1600C, tenth sound generator 1600LC, or eleventh sound generator 1600RC and the first woofer-integrated sound generator (W3) prevents this and reproduces natural sound close to the original sound. Acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and the vibrations and standing waves generated by the third sound generator 1600C, tenth sound generator 1600LC, or eleventh sound generator 1600RC can be reduced. In addition to vibrations caused by the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and deterioration in sound quality, but the asymmetric structure of one of the third sound-generating device 1600C, the tenth sound-generating device 1600LC, and the eleventh sound-generating device 1600RC and the second woofer-integrated sound-generating device (W4) can prevent this and reproduce natural sound that is close to the original sound.

For example, a 1-3 pad 713 may be arranged on at least one side of the sixth partition 1711 facing the first woofer-integrated sound-generating device (W3). A 1-1 pad 711 may be arranged on the side opposite the 1-3 pad 713. For example, a 1-5 pad 715 may be arranged on at least one side of the first partition 1721 facing the first woofer-integrated sound-generating device (W3).

The remaining configuration is the same as or similar to that of FIG. 21F, and therefore a detailed description thereof will be omitted.

[0326] 21H , one of the first partition 1721, the second partition 1722, and the third partition 1723 may include one or more vent portions.

As another example, as shown in FIG. 19I, the third partition 1723 may not include one or more vents. The remaining configuration is the same as or similar to that of FIG. 21H, and therefore a detailed description thereof will be omitted.

Descriptions of the same content as those described in Figures 15A to 15I and / or 18A to 21I can be omitted or simplified.

[0332] 22A to 22I, the first woofer-integrated sound-generating device (W3) may be arranged symmetrically with one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. The first woofer-integrated sound-generating device (W3) may be arranged on the same line as one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. The second woofer-integrated sound-generating device (W4) may be arranged symmetrically with one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. The second woofer-integrated sound-generating device (W4) may be arranged on the same line as one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C. With this configuration, the sound reproduction positions can be aligned on the same line, creating the effect of sounds being reproduced at the same position compared to an asymmetric configuration. This improves the perception of the sound position, thereby improving the sense of sound localization. Referring to Figures 22F and 22G, the 10-1 pad 741 and the 10-3 pad 743 can be arranged symmetrically with one of the 1-1 pad 711, the 1-3 pad 713, the 2-1 pad 811, the 2-3 pad 813, the 3-1 pad 911, and the 3-3 pad 913.

The second woofer-integrated sound-generating device (W4) may be arranged asymmetrically with one of the first sound-generating device 1600L, the second sound-generating device 1600R, and the third sound-generating device 1600C.

In addition to vibrations from the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and deterioration in sound quality, but the asymmetric structure of one of the first sound generator 1600L, second sound generator 1600R, or third sound generator 1600C and the first woofer-integrated sound generator (W3) can prevent this and reproduce natural sound close to the original sound. Acoustic reinforcement or cancellation due to vibration interference between the vibrations and standing waves generated by the second woofer-integrated sound generator (W4) and the vibrations and standing waves generated by the first sound generator 1600L, second sound generator 1600R, or third sound generator 1600C can be reduced. In addition to vibrations caused by the sound source being reproduced, unwanted acoustic reinforcement or destructive interference due to external interference can cause sound distortion and deterioration in sound quality. However, the asymmetric structure of one of the first sound-generating device 1600L, second sound-generating device 1600R, and third sound-generating device 1600C and the second woofer-integrated sound-generating device (W4) can prevent this and reproduce natural sound close to the original sound.
