Description

[Technical field]

[0001] This specification relates to devices, and more particularly to devices capable of outputting sound. [Background technology]

[0002] The display device is used as a screen for displaying images in electronic products or home appliances such as a device (or electronic device), television, monitor, laptop, smartphone, tablet computer, electronic pad, wearable device, watch phone, portable information device, navigation device, or vehicle control display device.

[0003] The display device may include a display panel for displaying images, and an audio device for outputting sounds associated with the images.

[0004] However, in a display device, sound output from an audio device travels behind or below the display panel, and sound quality deteriorates due to interference between sound waves reflected by walls or the ground, which makes it difficult to transmit sound accurately and reduces the viewer's sense of immersion. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present specification recognized the problems with the above-mentioned device and conducted various research and experiments to improve sound quality by making the sound travel in the front direction of the vibrating member when a user listens to sound in front of the vibrating member (or display member, or display module, or passive vibrating member). Through various experiments, they invented a device with a new structure that can generate sound that can travel in the front direction of the vibrating member and improve sound quality.

[0006] One or more embodiments of the present specification provide a device that can vibrate a vibrating member using sound generated by vibration (or driving) of an sound generating device (or vibration generating device) configured on the rear surface of a support member (or cover bottom) on the rear surface of the vibrating member, thereby outputting sound in a front direction (or forward) of the vibrating member.

[0007] One or more embodiments of the present specification provide an apparatus that can improve acoustic characteristics and / or sound pressure characteristics by generating positive phase components of sound and negative phase components of sound by arranging sound generating devices in opposite directions.

[0008] One or more embodiments of the present disclosure provide an apparatus having an anti-phase amplification hybrid radiation structure that is routed through a circuit cover (or cover shield) that covers a circuit portion.

[0009] One or more embodiments of the present specification provide a device that can output sound generated by vibration of an acoustic generating device in a vertical direction (or downward and / or upward direction) through an acoustic path passing through the front direction of the vibrating member and a circuit cover (or cover shield) covering the circuit portion.

[0010] One or more embodiments of the present specification provide a device that can improve the acoustic characteristics and / or sound pressure characteristics of a sound range, including a low-frequency range, by radiating out-of-phase sound through the lower end of a circuit cover (or cover shield) and radiating in-phase sound diffracted through the upper end of the circuit cover.

[0011] One or more embodiments of the present disclosure provide a device in which an acoustic generating device is arranged in a reverse direction so that anti-phase components of sound can radiate through holes in a support member and / or a circuit cover, thereby improving acoustic characteristics and / or sound pressure characteristics.

[0012] One or more embodiments of the present specification provide a device in which a first phase sound generated by vibration of an acoustic generating device and a second phase sound different or opposite to the first phase sound are output (or radiated, or emitted, or diffracted) in different directions, thereby improving acoustic characteristics and / or sound pressure characteristics.

[0013] The problems solved by one or more embodiments of the present specification are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by a person having ordinary skill in the art to which the present invention pertains from the description below.

[0030] Throughout the drawings and detailed description, unless otherwise stated, the same drawing numerals should be understood to refer to the same components, features or structures. The relative size and depiction of these elements may be exaggerated for clarity, explanation, or convenience. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Reference will now be made in detail to the embodiments of the present specification, examples of which may be illustrated in the accompanying drawings. In the following description, if a specific description of well-known functions or configurations unnecessarily obscures the gist of the present specification, the specific description may be omitted for the sake of brevity. The progression of steps and / or operations described is exemplary, but the order of steps and / or operations is not limited to those described herein and may be modified, except for steps and / or operations that necessarily occur in a particular order. Unless otherwise specified, the same reference numerals may generally refer to similar components even if they are illustrated in different drawings. In one or more embodiments, identical components (or components having the same name) in different drawings may have the same or substantially the same functions and characteristics, unless otherwise specified. The names of the respective components used in the following description are selected for convenience and may differ from the actual products.

[0032] The advantages and features of the present specification and methods for achieving them will become apparent from the following detailed description of various embodiments with reference to the accompanying drawings. However, the present specification is not limited to the embodiments disclosed below, and may be embodied in various different forms, and the embodiments are provided solely for the purpose of completing the disclosure of the present specification and fully conveying the scope of the technical ideas of the present specification to those skilled in the art to which the technical ideas of the present specification belong.

[0033] The shapes, dimensions, areas, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of this specification are merely illustrative, and the present specification is not limited to the details shown in the drawings.

[0034] When the terms "comprise", "have", "consist", "comprise", "formed", etc. are used as mentioned in this specification, other parts can be added unless "only" or "only" is used. The terms used in this specification are used only to describe a particular embodiment and are not intended to limit the scope of the specification. The terms used in this specification are used only to describe an exemplary embodiment and are not intended to limit the scope of the specification. The terms expressing elements in the singular include the plural unless otherwise expressly stated.

[0035] An "embodiment" may be an illustrative example. Unless expressly stated otherwise, any implementation described in this specification as an "embodiment" or "example" should not necessarily be construed as preferred or advantageous over other implementations.

[0036] In one or more embodiments, components, features, or corresponding information (e.g., levels, ranges, dimensions, sizes, etc.) may be interpreted as including an error or tolerance range even if an explicit description of these error or tolerance ranges is not provided. The error or tolerance range may be caused by various factors (e.g., process factors, internal or external impacts, noise, etc.).

[0037] In the case of a description of a location relationship, when a location relationship is described between two parts using words such as "on" or "above" or "on top", "under" or "below" or "beneath", "near", "adjacent to", "beside", "next to", or "on a side of", one or more other parts may be located between the two parts, unless "just", "immediately", "close(ly)", or "direct(ly)" is used. For example, when structures are described as being located "above or over," "on top," "under or below," "on the bottom," "near," "adjacent to," "beside," "next to," or "on a side of," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. For example, when structures are described as being located "on or over," "on top," "under or below," "on the bottom," "near," "adjacent to," "beside," or "next to," this description must be interpreted to include cases where the structures touch each other and have a third structure disposed between them. Also, unless otherwise specified, terms such as "front", "back", "dorsal", "left", "right", "top", "bottom", "downward", "upward", "top", "bottom", "column", "row", "vertical", "horizontal", etc. refer to any frame of reference.

[0038] In the case of descriptions of temporal relationships, when the temporal sequence is described using "after," "subsequent," "next," "before, preceding or prior to," etc., consecutive or non-consecutive cases can also be included, since "just," "immediately," or "directly" are not used.

[0039] Although the terms "first", "second", etc. are used to describe various components, these components are not limited to these terms, e.g., a particular order, priority, or number of components. These terms are used only to distinguish one component from another component. Thus, a first component referred to below may also be a second component within the technical spirit of this specification. Furthermore, the first element, the second element, etc. may be named arbitrarily according to the convenience of a person skilled in the art without departing from the scope of this specification. Terms such as "first", "second", etc. may be used to distinguish components from each other, but the function or structure of the component is not limited by the ordinal number before the component or the name of the component.

[0040] In describing components of this specification, terms such as first, second, A, B, (a), (b), etc. may be used. Such terms are used to distinguish the components from other components, and are not used to define the nature, basis, order, or number of the components.

[0041] When a component or layer is described as being "connected," "bonded," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other components, but that other components or layers may be "disposed" or "interpodated" between each component that may be indirectly connected or connected unless specifically and explicitly stated.

[0042] When a component or layer is described as being in "contact with" or "overlapping" another component or layer, it should be understood that the component may be in direct contact with or overlaid on the other component or layer, but one or more other components or layers may be "disposed" or "interpodded" between each component or layer that may be in indirect contact or overlaid unless otherwise expressly described. For example, for purposes of this specification, terms such as "overlap" and "overlapping" should be understood as "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection, and "overlapping, electrically and / or physically connected" by, for example, surface-to-surface connection.

[0043] Terms such as "line" or "direction" should not be construed solely in terms of a geometric relationship in which the respective lines or directions are aligned or perpendicular to one another, but can refer to lines or directions that have a broader orientation within which the components of this specification can functionally operate.

[0044] The term "at least one" should be understood to include all possible combinations of one or more of the associated items. For example, the meaning of "at least one of the first, second, and third items" may include only combinations of any of the individual items, the first, second, and third items, and not just combinations of all three items listed, or combinations of items presented from two or more of the first, second, or third items.

[0045] The phrase "first component", "second component" and / or "third component" should be understood as one of the first, second and third components or any or all combinations of the first, second and third components. For example, A, B and / or C can be considered as A only, B only, C only, any combination of two of A, B and C, and all of A, B and C. Furthermore, the phrase "component A / component B" should be understood as component A and / or component B.

[0046] In one or more embodiments, the terms "between" and "in" may be used interchangeably for convenience only, unless otherwise noted. For example, the phrase "between multiple components" may also be understood as "among multiple components." In other embodiments, the phrase "among multiple components" may also be understood as "between multiple components." In one or more embodiments, the number of components may be two. In one or more embodiments, the number of components may be more than two.

[0047] In one or more embodiments, the term "different from" may be understood to mean that any element is different from the other element.

[0048] In one or more embodiments, the terms "one or more of" and "one or more of" may be used interchangeably for convenience only, unless otherwise specified. For example, the term "one or more of" can also be understood as "one or more of." For example, the term "one or more of" can also be understood as "one or more of."

[0049] In this specification, the term "display device" may include a display device such as a display module (or display member) including a display panel and a driver for driving the display panel. The display module may also include a set electronic apparatus or set device such as a notebook computer, a television, a computer monitor, an automotive apparatus or other shapes of a vehicle, which is a complete product or final product including a display module such as a liquid crystal display module and a light-emitting display module (organic light-emitting display module), a mobile electronic apparatus such as a smartphone or an electronic pad, or other mobile electronic apparatus.

[0050] Therefore, the display device in this specification may include the display device itself, such as a liquid crystal display module or an organic light-emitting display module, as well as an application product or a set device that is an end-user device including a liquid crystal display module or an organic light-emitting display module.

[0051] The display panel used in one or more embodiments of the present specification may be any type of display panel, such as a liquid crystal display panel, an organic light emitting display panel, and a micro light emitting diode display panel, but the embodiments of the present specification are not limited to this type of display panel. For example, the display panel may be a display panel that can generate sound by being vibrated by a vibration generating device according to an embodiment of the present specification. The display panel applied to the device or display device according to the embodiments of the present specification is not limited to the shape or size of the display panel.

[0052] According to one or more embodiments of the present specification, when the display panel is a liquid crystal display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels formed at each of the intersection regions of the plurality of gate lines and the plurality of data lines. The display panel may include a first substrate including a thin film transistor that is a switching element for adjusting the light transmittance of each pixel, a second substrate including a color filter and / or a black matrix, and a liquid crystal layer formed between the first substrate and the second substrate.

[0053] According to one or more embodiments of the present specification, when the display panel is an organic light emitting display panel, the display panel may include a plurality of gate lines, a plurality of data lines, and a plurality of pixels formed at each of the intersection regions of the gate lines and the data lines. The display panel may include a substrate including a thin film transistor, which is an element for selectively applying a voltage to each pixel, an organic light emitting element layer on the substrate, and an encapsulation layer (or encapsulation substrate) disposed on the substrate to cover the organic light emitting element layer. The encapsulation layer or encapsulation substrate may protect the thin film transistor and the organic light emitting element layer from external impact and prevent moisture or oxygen from penetrating into the organic light emitting element layer. The organic light emitting element layer may further include an inorganic light emitting layer, for example, a nano-sized material layer and / or a quantum dot light emitting layer. In another embodiment of the present specification, an inorganic light emitting layer, for example, a nano-sized material layer and / or a quantum dot light emitting layer may be used instead of the organic light emitting element layer. As another embodiment herein, micro light emitting diodes can be used instead of the organic light emitting device layer.

[0054] The device including the vibration device (or vibration generating device) in this specification may be applied to a vehicle by being realized as a user interface device such as a central control panel in an automobile. For example, the user interface device for a vehicle may be configured between the two front seats so that the sound generated by the vibration of the display module is propagated toward the inside of the vehicle in a wider range. Therefore, the audio experience in the vehicle may be improved compared to the case where the vehicle has speakers only on the interior sides.

[0055] The features of one or more embodiments of the present specification may be partially or fully combined or combined with each other, and various technical interlocking and operation may be possible, and each embodiment may be implemented independently of each other, or may be implemented together in a linked relationship. In one or more embodiments of the present specification, the components of each device according to various embodiments of the present specification may be operably combined or configured.

[0056] The terms used in this specification (including technical and scientific terms) may have the same meaning as that understood by a person having ordinary knowledge in the technical field to which this specification belongs. Furthermore, terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning in the context of the relevant technology, and should not be interpreted as idealized or overly formal unless otherwise specified.

[0057] Hereinafter, a vibration device according to various embodiments of the present specification, a vibration device, and a vehicle including the same will be described in detail with reference to the accompanying drawings. The reference numbers for components in each drawing may refer to similar components, although the same components may be illustrated in other drawings, unless otherwise specified. Furthermore, for convenience of explanation, the scales, dimensions, sizes, and thicknesses of the components illustrated in the drawings may have scales, dimensions, sizes, and thicknesses different from the actual scales, dimensions, sizes, and thicknesses, and therefore are not limited to the scales, dimensions, sizes, and thicknesses illustrated in the drawings.

[0063] The vibrating member 100 according to an embodiment of the present specification may include a display panel 110 for displaying an image. For example, the image may include an electronic image, a digital image, a still image, or a video image. For example, the display panel 110 may include a liquid crystal display panel having a plurality of pixels for realizing a black and white or color image, and the type of the display panel is not limited thereto. For example, the display panel 110 may be an organic light-emitting display panel, an electrophoretic display panel, a micro light-emitting diode display panel, an electrowetting display panel, an inorganic light-emitting display panel, or a quantum dot light-emitting display panel, but the embodiment of the present specification is not limited thereto.

[0064] The support member 300 may be disposed on the rear surface of the vibration member 100. For example, the support member 300 may be configured to cover the rear surface of the vibration member 100. The support member 300 may include a rear portion 310 that covers the rear surface of the vibration member 100. The support member 300 may be made of a glass material, a plastic material, a metal material, or a laminated structure thereof, but the embodiment of the present specification is not limited thereto. For example, the support member 300 may be a cover bottom, a rear structure, a back cover, a first structure, a housing, a rear cover, or a set cover, but the embodiment of the present specification is not limited thereto.

[0065] The support member 300 (or the vibration member 100) may include a first region 300A1 and a second region 300A2. For example, the rear part 310 of the support member 300 may include a first region 300A1 and a second region 300A2. For example, the rear part 310 of the support member 300 may be divided into the first region 300A1 and the second region 300A2 based on a center line (or a first center line) (CL1) of a first length (or a lateral length) parallel to a first direction (X). For example, the first region 300A1 and the second region 300A2 may have the same size or different sizes in the rear part 310. For example, the first region 300A1 may be a first rear region, a left region, or a rear left region, and the second region 300A2 may be a second rear region, a right region, or a rear right region. For example, the first direction (X) may be the longitudinal direction of a long side of the device or support member 300, the lateral direction, the horizontal direction, or the X-axis direction in an XYZ coordinate system.

[0066] The support member 300 according to the embodiment of the present specification may further include a reinforcing portion 320. The reinforcing portion 320 may be realized to reinforce the rigidity of the support member 300. The reinforcing portion 320 may be configured on the rear portion 310 of the support member 300. For example, the reinforcing portion 320 may be configured on one or more of the middle portion and the edge portion of the rear portion 310. For example, the reinforcing portion 320 may be a reinforcing pattern, a rigid portion, a rigid reinforcing pattern, or a rigid reinforcing portion, etc., but the embodiment of the present specification is not limited thereto.

[0067] The reinforcing portion 320 according to the embodiment of the present specification may include a first reinforcing member 321. The first reinforcing member 321 may be disposed along an edge portion of the rear surface of the support member 300. For example, the first reinforcing member 321 may be disposed along an edge portion of the rear portion 310 of the support member 300. For example, the first reinforcing member 321 may protrude from the edge portion of the rear portion 310 of the support member 300 toward the rear surface of the support member 300 to have a preset height. The first reinforcing member 321 may prevent or reduce the warping phenomenon of the device or the vibrating member 100 by reinforcing the rigidity of the support member 300 or the rigidity of the rear portion 310 of the support member 300. For example, the first reinforcing member 321 may be a first reinforcing pattern, a first rigidity reinforcing pattern, a first rigidity reinforcing portion, an edge reinforcing pattern, or a frame reinforcing pattern, but the embodiment of the present specification is not limited thereto.

[0068] The reinforcing portion 320 according to the embodiment of the present specification may further include one or more second reinforcing members 322. The one or more second reinforcing members 322 may be configured in a middle portion of the rear portion 310 of the support member 300. For example, the one or more second reinforcing members 322 may be configured in the rear portion 310 of the support member 300 to be parallel to the first direction (X). For example, the one or more second reinforcing members 322 may be configured in a line shape having a width parallel to a second direction (Y) intersecting the first direction (X) and a length parallel to the first direction (X), but the embodiment of the present specification is not limited thereto. For example, the second direction (Y) may be the short side length direction, the longitudinal direction, the vertical direction, or the Y-axis direction in the XYZ coordinate system of the device or the support member 300. For example, the second reinforcing member 322 may be a second reinforcing pattern, a second rigid reinforcing pattern, a second rigid reinforcing portion, an edge reinforcing pattern, a secondary reinforcing pattern, or an auxiliary reinforcing pattern, but the embodiment of the present specification is not limited thereto. For example, one or more of the second reinforcing members 322 may be optional.

[0069] According to an embodiment of the present specification, the sound generating device 500 may be configured on the support member 300. For example, the sound generating device 500 may be configured on the rear surface of the rear portion 310 of the support member 300. The sound generating device 500 may be configured to output a first sound (S1) and a second sound (S2) generated by vibration (or driving) in different directions (FD, VD) with respect to the vibrating member 100. For example, the sound generating device 500 may be configured to output a sound (or sound wave) generated by vibration (or driving) by a driving signal in a front direction (FD) and a vertical direction (VD) of the vibrating member 100 (e.g., a forward direction or a first direction (FD) and a vertical direction or a second direction (VD)). For example, the sound generating device 500 may be a vibration generating device, a sound wave generating device, an active vibration generating device, or an active vibration generating device, but the embodiment of the present specification is not limited thereto.

[0070] The sound generating device 500 according to an embodiment of the present specification may be configured to output a first sound (S1) generated by vibration (or driving) in a front direction (FD) of the vibrating member 100, and output a second sound (S2) different from the first sound (S1) generated by vibration (or driving) in a vertical direction (VD) of the vibrating member 100. For example, the sound generating device 500 may be configured to output the first sound (S1) generated by vibration (or driving) in the front direction (FD) of the vibrating member 100, and output the second sound (S2) different from the first sound (S1) generated by vibration (or driving) in a lower direction of the vibrating member 100, but the embodiment of the present specification is not limited thereto. For example, the sound generating device 500 may be configured to output the second sound (S2) in an upper or lower direction of the vibrating member 100. For example, the sound generating device 500 may be configured to output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) and output a second sound (S2) in a direction different from the front direction (FD) of the vibrating member 100, but the examples of the present specification are not limited thereto. For example, the different direction may be a direction perpendicular to the front direction of the vibrating member 100. For example, the first sound (S1) may be different from the second sound (S2). For example, the first sound (S1) may have a different phase from the second sound (S2). For example, the first sound (S1) may have a first phase, and the second sound (S2) may have a second phase different from the first phase. For example, the first sound (S1) and the second sound (S2) may have opposite phases. For example, the first sound (S1) may have an opposite phase to the second sound (S2). For example, the first sound (S1) may include a frequency band of 100 Hz to 3 kHz, but the embodiments of this specification are not limited thereto. For example, the second sound (S2) may include a frequency band of 100 Hz to 20 kHz, but the embodiments of this specification are not limited thereto.

[0071] According to an embodiment of the present specification, the first sound (or sound wave) (S1) generated by the vibration (or drive) of the sound generating device 500 vibrates the support member 300, and thus the first sound (S1) generated by the vibration of the vibrating member 100 due to the vibration of the support member 300 can be output in the front direction (FD) of the vibrating member 100. For example, the vibrating member 100 vibrates due to the first sound (or sound wave) (S1) generated by the vibration (or drive) of the sound generating device 500, and can output the first sound (or sound wave) in the front direction (FD).

[0072] According to an embodiment of the present specification, the second sound (or sound wave) (S2) generated by the vibration (or driving) of the sound generating device 500 may be output in the vertical direction (VD) of the vibrating member 100 via the inside (or internal sound path or sound path) of the sound generating device 500. For example, the vertical direction (VD) of the vibrating member 100 may be a direction perpendicular to the front direction (FD) of the vibrating member 100. For example, the vertical direction (VD) of the vibrating member 100 may be a direction parallel to the second direction (Y) and / or a direction perpendicular to the ground. For example, the sound generating device 500 may be configured to output the second sound (or sound wave) (S2) in a direction perpendicular to the ground. For example, the vertical direction (VD) of the vibrating member 100 according to an embodiment of the present specification may be a direction from the vibrating member 100 toward the ground or a direction toward the bottom of the vibrating member 100.

[0073] The sound-generating device 500 according to an embodiment of the present disclosure may include a rectangular shape or a polygonal shape including curved portions, but the embodiment of the present disclosure is not limited thereto.

[0074] A sound-generating device 500 according to an embodiment of the present specification may include a plurality of sound-generating devices 510, 520. For example, the sound-generating device 500 may include a first and a second sound-generating device (or a first and a second sound-generating device) 510, 520 arranged in a first region 300A1 and a second region 300A2 of the support member 300, respectively, but the embodiment of the present specification is not limited thereto. For example, the first region 300A1 and the second region 300A2 may be a rear region of the support member 300. For example, the first region 300A may be a left rear region of the support member 300, but the embodiment of the present specification is not limited thereto. The second region 300B may be a right rear region of the support member 300, but the embodiment of the present specification is not limited thereto.

[0075] As shown in FIG. 2, only one first sound generating device 510 and one second sound generating device 520 are illustrated. However, the number of the first sound generating devices 510 and the second sound generating devices 520 is not limited thereto. For example, the number of the first sound generating devices 510 is m, and the number of the second sound generating devices 520 is n. Here, m and n are integers of 1 or more, respectively, and m and n can be the same or different. Meanwhile, each of the first sound generating devices 510 and each of the second sound generating devices 520 can have the same or basically the same structure, or can have different structures.

[0076] 2 to 4, each of the first and second sound generating devices 510, 520 according to an embodiment of the present specification may include a case member 511, a sound generator 513, and a sound guide member 515.

[0077] The case member 511 may be disposed on the rear surface of the support member 300. For example, the case member 511 may be disposed on the rear portion 310 of the support member 300.

[0078] The sound generator 513 may be configured to output sound (or sound waves) generated by vibration (or drive) by a drive signal. For example, the sound generator 513 may be configured to output sound (or sound waves) in both directions (or up-down or front-back directions) along the third direction (Z). For example, the sound generator 513 may be configured to output sound (or sound waves) in the front direction (FD) of the vibrating member 100, and at the same time output sound (or sound waves) in the rear direction opposite to the front direction (FD) of the vibrating member 100. The third direction (Z) may be the thickness direction or height direction of the vibrating member 100, or the Z-axis direction in the XYZ coordinate system.

[0079] In this specification, directional indications such as "front", "rear" and the like should be understood with respect to the display member (or vibrating member) or the display member. For example, "front" or "forward" means a position or orientation toward a user viewing the content displayed on the display member (or vibrating member), and "rear" or "rearward" may be the opposite. In general, directional indications may be defined with respect to the orientation of the device during intended use. The rear of the display member (or vibrating member) may mean the side opposite to the side on which the content of the display member (or vibrating member) is displayed.

[0080] The sound generator 513 may have a front surface and a rear surface (or rear surface). The front surface of the sound generator 513 may face the rear direction of the device. The rear surface of the sound generator 513 may face the support member 300. For example, the rear surface of the sound generator 513 may directly face the support member 300. For example, the sound generator 513 may have an arrangement structure in a reverse direction with respect to the rear surface of the support member 300 or the rear surface of the device. As a result, the sounds output in the front direction and the rear direction of the sound generator 513 may have different phases, for example, opposite phases. For example, the sound output in the front direction of the sound generator 513 (or the front sound) may have a positive phase, and the sound output in the rear direction of the sound generator 513 (or the rear sound) may have a negative phase or an opposite phase with respect to the front sound of the sound generator 513.

[0081] According to one embodiment of the present specification, sound output from the sound generator 513 in the front direction (FD) of the vibrating member 100 (or the rear sound of the sound generator 513) vibrates the support member 300, and thus the sound generated by the vibration of the vibrating member 100 due to the vibration of the support member 300 can be output in the front direction (FD) of the vibrating member 100 as the first sound (S1).

[0082] The sound generator 513 may be disposed in the case member 511. The sound generator 513 may be configured to be supported or housed in the case member 511. For example, the case member 511 may be configured to house or accommodate the sound generator 513. The sound generator 513 may be disposed in the case member 511 so as to be spaced apart from the rear surface of the support member 300. For example, the case member 511 may be configured to space the sound generator 513 from the rear surface of the support member 300. For example, the sound generator 513 may be supported or housed in the case member 511 so as to have an inverse arrangement with respect to the rear surface of the support member 300 or the rear surface of the device.

[0083] The acoustic guide member (or acoustic guide frame) 515 may be disposed in the case member 511 and configured to cover the acoustic generator 513. The acoustic guide member 515 may be configured to cover the acoustic generator 513 and be spaced apart from the acoustic generator 513. An edge portion of the acoustic guide member 515 may be coupled or joined to the case member 511. The acoustic guide member 515 may be configured to cover a portion of the reinforcing portion 320 on the back surface of the support member 300.

[0084] The acoustic guide member 515 may be configured to guide the output direction of the second sound (S2) output from the acoustic generator 513. For example, the acoustic guide member 515 may be configured to guide the sound output from the acoustic generator 513 (or the front sound of the acoustic generator 513) in the vertical direction (VD) of the vibration member 100.

[0085] The acoustic guide member 515 may be configured to include an acoustic adjustment surface for guiding the sound output from the acoustic generator 513 (or the front sound of the acoustic generator 513) in the vertical direction (VD) of the vibration member 100. For example, the sound output from the acoustic generator 513 to the acoustic guide member 515 (or the front sound) may be diffracted by the acoustic adjustment surface and output (or radiated) in the vertical direction (VD) of the vibration member 100 as the second sound (S2), thereby improving the acoustic characteristics and / or sound pressure characteristics of the low frequency band for the second sound (S2).

[0086] The device (or electronic device) according to an embodiment of the present disclosure may further include a circuit cover 200 .

[0087] The circuit cover 200 may be coupled to the vibration member 100 and configured to cover the drive circuit unit 170 disposed on the back surface of the support member 300. For example, the drive circuit unit 170 may be on the back surface of the support member 300 and coupled to the vibration member 100. For example, the drive circuit unit 170 may include a printed circuit board 175 disposed on the back surface of the support member 300 and coupled to the vibration member 100. For example, the circuit cover 200 may be configured on the back surface of the support member 300 to cover the drive circuit unit 170 disposed on the back surface of the support member 300. For example, the circuit cover 200 may be on the back surface of the support member 300 and cover the printed circuit board 175. The drive circuit unit 170 may be disposed on an edge portion (or a lower edge portion) of one side of the support member 300. The circuit cover 200 may be configured to be disposed on an edge portion (or a lower edge portion) of one side of the support member 300 and cover the drive circuit unit 170. For example, the driving circuit unit 170 may be disposed at an edge portion (or a lower edge portion) on one side of the rear part 310 of the support member 300. The circuit cover 200 may be disposed at an edge portion (or a lower edge portion) on one side of the rear part 310 of the support member 300 and configured to cover the driving circuit unit 170. For example, the circuit cover 200 may be a cover shield, a metal cover, a protective cover, a circuit protection member, or the like, but the embodiments of the present specification are not limited thereto.

[0088] The circuit cover 200 according to an embodiment of the present specification may be arranged to overlap the sound generating device 500. For example, the sound generating device 500 may be configured on the back surface of the support member 300 so as to overlap the circuit cover 200. For example, the sound generating device 500 may be configured to output a second sound (S2) through the circuit cover 200. For example, the sound generating device 500 may be configured to overlap the back surface of the support member 300 and the circuit cover 200. For example, a part of the sound generating device 500 may be configured on the back surface 310 of the support member 300 so as to overlap a part of the circuit cover 200. For example, a part of the sound generating device 500 may be configured on the back surface 310 of the support member 300 so as to cover a part of the circuit cover 200. Thereby, a part of the sound generated by the sound generating device 500 may be output (or radiated) in the vertical direction (VD) of the vibration member 100 via a space (or an acoustic guide space) between the acoustic guide member 155 and the circuit cover 200. For example, the sound (or front sound) output from the acoustic generator 513 to the acoustic guide member 515 can be diffracted in the space (or acoustic guide space) between the acoustic guide member 155 and the circuit cover 200 as a second sound (S2) and output (or radiated) in the vertical direction (VD) of the vibration member 100.

[0089] According to an embodiment of the present specification, a part of the sound generated by the sound generating device 500 may be output in the vertical direction (VD) of the vibrating member 100 through the inside of the circuit cover 200. For example, a part of the sound generated by the sound generating device 500 may be output in the vertical direction (VD) of the vibrating member 100 through the space between the circuit cover 200 and the support member 300 (or the cover internal space). For example, a part of the sound output from the sound generator 513 to the support member 300 (or the rear sound of the sound generator 513) may be output in the vertical direction (VD) of the vibrating member 100 through the inside of the circuit cover 200. For example, a part of the sound output from the sound generator 513 to the support member 300 (or the rear sound of the sound generator 513) may be output in the vertical direction (VD) of the vibrating member 100 through the space between the circuit cover 200 and the support member 300 (or the internal space).

[0090] Referring to FIG. 3, the circuit cover 200 according to an embodiment of the present specification may further include a hole portion 217. The hole portion 217 may be configured on the circuit cover 200 around an end of the sound generating device 500.

For example, the hole portion 217 may include a plurality of holes 217h arranged in parallel to have a preset interval along the first direction (X). For example, the hole portion 217 may be a first hole, a vent hole, a ventilation hole, a duct hole, a first sound hole, a first sound output port, or a first sound emission portion, but the embodiment of the present specification is not limited thereto.

For example, the second sound (S2) may be output in the vertical direction (VD) perpendicular to the front direction (FD) of the vibration member 100 through the space (or the cover internal space) between the circuit cover 200 and the support member 300. For example, the second sound (S2) may be output in a vertical direction (VD) perpendicular to the front direction (FD) of the vibration member 100 through a space between the circuit cover 200 and the printed circuit board 175. According to an embodiment of the present specification, the sound output from the sound generator 513 to the sound guide member 515 (or the front sound of the sound generator 513) may be output as the second sound (S2) in the vertical direction (VD) of the vibration member 100 through the sound guide space (or the first sound path) between the sound guide member 515 and the circuit cover 200.

For example, the second sound (S2) output through the first sound path and a portion of the rear sound output through the second sound path may be combined with each other around the hole portion 217 or amplified and output in the vertical direction (VD) of the vibration member 100.

[0092] According to an embodiment of the present specification, the second sound (S2) output through the first sound path may have a frequency characteristic of the entire frequency range. A portion of the rear sound output through the second sound path may have a frequency characteristic of 3 kHz or less. As a result, a portion (or acoustic energy) of the sound (or rear sound) generated by the vibration of the sound generator 513 and released to the support member 300 is reused as a portion of the second sound (S2) output in the vertical direction (VD) of the vibrating member 100 through the second sound path, thereby improving the acoustic characteristics and / or sound pressure characteristics of the device, or improving the acoustic characteristics and / or sound pressure characteristics of the second sound (S2).

[0118] The light source unit 133 may be configured to irradiate light onto a light incident surface provided on the light guide plate 131. The light source unit 133 may be disposed (or housed) in the support member 300 so as to overlap an edge portion of the display panel 110. The light source unit 133 may be realized on the light source printed circuit board 135, and may include a plurality of light emitting diode elements each of which irradiates light onto the light incident surface of the light guide plate 131.

[0119] The reflective sheet 137 may be disposed (or housed) in the support member 300 so as to cover the rear surface of the light guide plate 131. The reflective sheet 137 may reflect the light incident from the light guide plate 131 back toward the light guide plate 131, thereby reducing or minimizing the loss of light.

[0120] The optical sheet unit 139 is disposed on the front surface of the light guide plate 131 and can improve the brightness characteristics of light output from the light guide plate 131. The optical sheet unit 139 according to an embodiment of the present specification may be a combination of one or more layers of a diffusion sheet, a prism sheet, a dual brightness enhancement film, and a lenticular sheet, or may be a composite sheet having a function of diffusing and collecting light, but the embodiment of the present specification is not limited thereto.

[0121] The guide panel 150 may be disposed at an edge portion of the rear surface of the display panel 110 and may support the edge portion of the rear surface of the display panel 110. The guide panel 150 may be supported by the support member 300 so as to overlap with the edge portion of the rear surface of the display panel 110, or may be housed in the support member 300. The guide panel 150 may be configured to surround each side of the display panel 110, but the embodiment of the present specification is not limited thereto. For example, the guide panel 150 may be disposed below the rear surface of the display panel 110 so as not to protrude outward beyond each side of the display panel 110. For example, the guide panel 150 may be a panel guide, a support frame, a support panel, or the like, but the embodiment of the present specification is not limited thereto.

[0122] A guide panel 150 according to one embodiment of the present disclosure may include a guide frame 151 and a guide side 153 .

[0123] The guide frame 151 may be connected to an edge portion of the rear surface of the display panel 110 and supported by the support member 300. For example, the guide frame 151 may have a rectangular band or belt shape having an opening that overlaps with a remaining middle portion excluding the edge portion of the rear surface of the display panel 110, but the embodiment of the present specification is not limited thereto. For example, the guide frame 151 may be in direct contact with the top surface of the backlight 130, for example, the top surface of the optical sheet unit 139, or may be spaced a certain distance from the top surface of the optical sheet unit 139.

[0124] The guide side portion 153 may be connected to the guide frame 151 and may enclose one side or a side surface of the support member 300. For example, the guide side portion 153 may be bent from the guide frame 151 toward the side surface of the support member 300 to enclose the side surface of the support member 300 or may be enclosed by the side surface of the support member 300.

[0125] The guide panel 150 according to an embodiment of the present specification may be made of a plastic material, a metal material, or a mixture of a plastic material and a metal material, but the embodiment of the present specification is not limited thereto. For example, the guide panel 150 may act as a vibration transmission member that transmits sound vibrations generated by the sound generating device 500 to the edge portion of the display panel 110. Therefore, the guide panel 150 can transmit sound vibrations generated by the sound generating device 500 to the display panel 110 without loss while maintaining the rigidity of the display panel 110. For example, the guide panel 150 may include a metal material in order to transmit sound vibrations generated by the sound generating device 500 to the display panel 110 while maintaining the rigidity of the display panel 110, but the embodiment of the present specification is not limited thereto.

[0126] The guide panel 150 according to an embodiment of the present specification may be connected or coupled to an edge portion of the rear surface of the display panel 110 via a coupling member (or a panel coupling member or a connecting member) 140. The coupling member 140 may be disposed between an edge portion of the rear surface of the display panel 110 and the guide panel 150 to allow the display panel 110 to be disposed or coupled to the guide panel 150. For example, the coupling member 140 may include an acrylic or urethane adhesive material, but the embodiment of the present specification is not limited thereto. For example, the coupling member 140 may include an acrylic adhesive material having relatively excellent adhesive strength and high hardness properties so that vibrations of the guide panel 150 are well transmitted to the display panel 110. For example, the coupling member 140 may include a double-sided foam adhesive tape or a double-sided foam adhesive pad having an acrylic adhesive layer, or an acrylic adhesive resin cured layer.

[0127] A front surface of the coupling member 140 according to an embodiment of the present specification may be disposed on the second substrate 113 or the first polarizing member 115 of the display panel 110. The coupling member 140 may be directly connected or bonded to an edge portion of the rear surface of the second substrate 113 to improve adhesion to the display panel 110. For example, the coupling member 140 may surround the side surface of the first polarizing member 115 to reduce or prevent side light leakage caused by the first polarizing member 115.

[0128] The coupling member 140 may have a certain thickness (or height). Thus, the coupling member 140, together with the guide frame 151 of the guide panel 150, may provide a sound transmission space (STS) between the display panel 110 and the backlight 130. The coupling member 140 may be disposed on the guide frame 151 of the guide panel 150 to have a four-sided closed type or closed loop shape, but the embodiment of the present specification is not limited thereto. For example, the coupling member 140 may seal the sound transmission space (STS) provided between the rearmost surface of the display panel 110 and the uppermost surface of the backlight 130, which face each other across the opening of the guide panel 150, thereby preventing or minimizing leakage (or loss) of sound pressure transmitted to the sound transmission space (STS). The sound transmission space (STS) may be a sound pressure generation space in which sound pressure is generated by the vibration of the backlight 130, or a panel vibration space that smooths the vibration of the display panel 110. For example, the sound transmission space (STS) can be an air gap, a gap space, a sonic transmission section, or an acoustic transmission section, etc., but examples herein are not limited thereto.

[0138] The support member 300 according to an embodiment of the present disclosure may further include a forming portion 340 .

[0139] The forming portion 340 may protrude from the rear portion 310 of the support member 300 in a rear direction of the support member 300. The forming portion 340 may protrude from the rear portion 310 of the support member 300 in a rear direction of the support member 300 to support the printed circuit board 175. For example, the printed circuit board 175 may be supported by the forming portion 340 or fixed to the forming portion 340.

[0140] In an apparatus according to an embodiment of the present disclosure, the circuit cover 200 may be configured to protect the drive circuit section 170. The circuit cover 200 may be configured to cover the drive circuit section 170.

[0141] The circuit cover 200 according to one embodiment of the present disclosure may include a first cover portion 211 , a second cover portion 213 , and a third cover portion 215 .

[0142] The first cover portion 211 may be configured to cover the printed circuit board 175 of the driving circuit unit 170. For example, the first cover portion 211 may be disposed on the rear surface of the support member 300 and cover the printed circuit board 175 to protect the printed circuit board 175.

[0143] The second cover part 213 may extend from the first cover part 211 to one side of the support member 300. For example, the second cover part 213 may extend from one side of the first cover part 211 to be inclined toward the side part 330 of the support member 300. The second cover part 213 may be inclined with respect to the rear surface of the support member 300. For example, the second cover part 213 may be inclined from one side of the first cover part 211 toward the rear part 310 of the support member 300. The second cover part 213 may include a hole part 217. The hole part 271 may include one or more holes 217h penetrating the second cover part 213 of the circuit cover 200. For example, the one or more holes 217h may be formed in the second cover part 213. For example, a portion of the second sound (S2) may be output through the one or more holes 217h.

[0144] The third cover part 215 may be extended from the second cover part 213 to cover one side of the vibrating member 100. The third cover part 215 may be extended from the second cover part 213 to cover the plurality of circuit films 171, the plurality of data driving integrated circuits 173 of the driving circuit part 170, and one side of the guide panel 150.

[0145] The second cover part 213 may be configured to be inclined between the first cover part 211 and the third cover part 215. For example, the distance between the second cover part 213 and the rear surface of the support member 300 may be gradually decreased from one side of the first cover part 211 to the third cover part 215. For example, the angle between the inner surface of the first cover part 211 and the inner surface of the second cover part 213 may be an obtuse angle. For example, the angle (or first angle) (θ1) between the inner surface of the first cover part 211 and the inner surface of the second cover part 213 may be 160 degrees to 180 degrees or 165 degrees to 175 degrees so that a part of the second sound is smoothly output (or radiated) through the space (or sound path) between the circuit cover 200 and the printed circuit board 175 and the hole part 217, but the embodiment of the present specification is not limited thereto.

[0146] In an apparatus according to an embodiment of the present disclosure, the damping member 600 may be disposed on a rear surface of the support member 300 around the sound-generating device 500. The damping member 600 may be disposed on a rear portion 310 of the support member 300 around the sound-generating device 500. The damping member 600 may be configured to be coupled to the circuit cover 200.

[0147] The damping member 600 according to an embodiment of the present specification may include a fixed portion 601, a damping portion 603, and a mass portion 605, but the embodiment of the present specification is not limited thereto. For example, the damping member 600 may include at least the damping portion 603.

[0148] The fixing part 601 may be fixed to the support member 300 at the periphery of the sound generating device 500. For example, the fixing part 601 may be fixed to the rear part 310 of the support member 300 at the periphery of one side of the sound generating device 500. For example, the fixing part 601 may be fixed to the rear part 310 of the support member 300 by a fastening member 600a such as a screw or a bolt, but the embodiments of the present specification are not limited thereto. For example, the damping member 600 may be fixed to the rear part of the support member 300 by a fastening member (or fixing member) 600a.

[0149] The damping part 603 may be connected to the fixed part 601 and configured to be spaced apart from the rear surface of the support member 300. For example, the damping part 603 may extend from one side (or a first side or a first portion) of the fixed part 601. For example, the damping part 603 may include a vertical part extending vertically from one side (or a first side or a first portion) of the fixed part 601, and a horizontal part extending from the vertical part in parallel with the rear surface of the support member 300. For example, the damping part 603 may extend from one side (or a first side or a first portion) of the fixed part 601 to have a "┗" or "L" shape, but the embodiment of the present specification is not limited thereto. Thus, the damping part 603 may be spaced apart from the rear surface of the support member 300. For example, the damping part 603 may be a vibration lever, a vibration piece, a damping plate, a vibration body, a cantilever beam, or the like, but the embodiment of the present specification is not limited thereto. The damping unit 603 can reduce or absorb noise by vibrating due to vibrations generated by the vibration (or driving) of the sound generating device 500. For example, the damping unit 603 can reduce or absorb noise by dynamically vibrating due to vibrations generated by the vibration (or driving) of the sound generating device 500.

[0150] The mass portion 605 according to an embodiment of the present specification may be configured in the damping portion 603. The mass portion 605 may be configured to increase the weight of the damping portion 603. The mass portion 605 may be configured of a material capable of increasing the weight of the damping portion 603. For example, the mass portion 605 may include a mass structure having a metal material or a non-metal material.

The hemming portion may include a plurality of extensions that extend from the damping portion 603. The hemming portion may be configured such that the ends are bent into a curved shape and overlap each other or parallel to each other. Thus, the mass portion 605 including the hemming portion may be configured by one or more bending steps on the extension of the damping portion 603. The mass portion 605 may be integrated with the damping portion 603.

[0152] The mass portion 605 according to the embodiments of the present specification increases the weight of the damping portion 603 and reduces the natural frequency of the damping portion 603, so that the vibration frequency of the sound-generating device 500 that generates noise can be reduced or absorbed by the vibration of the damping portion 603, thereby reducing the noise generated by the vibration (or driving) of the sound-generating device 500.

[0153] 5 and 6, the damping member 600 according to an embodiment of the present disclosure may further include a connecting portion 607.

[0154] The connecting portion 607 may be configured to be connected to the circuit cover 200. The connecting portion 607 may be configured to be connected between the fixing portion 601 and the circuit cover 200. For example, the connecting portion 607 may extend from the other side (or the second side or the second portion) of the fixing portion 601 and be connected to the circuit cover 200. For example, the connecting portion 607 may include a vertical portion extending vertically from the other side (or the second side or the second portion) of the fixing portion 601 and a horizontal portion extending from the vertical portion to overlap with a part of the circuit cover 200. For example, the connecting portion 607 may extend from the other side (or the second side or the second portion) of the fixing portion 601 to have a "┛" or inverted "L" shape.

[0155] The connecting portion 607 may be connected to a part of the circuit cover 200 by an adhesive member such as an adhesive or double-sided tape. The connecting portion 607 may be connected to an inner surface of the first cover portion 211 of the circuit cover 200 by an adhesive member. The connecting portion 607 may minimize or suppress vibration of the circuit cover 200, thereby reducing or absorbing noise generated by vibration (or driving) of the sound generating device 500.

[0156] Sound or vibration generated by the vibration (or driving) of the sound generating device 500 may be transmitted to the circuit cover 200, and noise may be generated by the vibration of the circuit cover 200. Thus, the damping member 600 can reduce or suppress the noise generated by the vibration of the circuit cover 200 by suppressing or reducing the vibration of the circuit cover 200 generated by the vibration (or driving) of the sound generating device 500.

The first support part 511a may include a substantially rectangular shape having one side in a semicircular shape. The first support part 511a may include an accommodating hole 511h that accommodates the sound generator 513. For example, the first support part 511a may be a plate having the accommodating hole 511h. For example, the first support part 511a may be a support plate having the accommodating hole 511h. For example, the accommodating hole 511h may be a support hole or an insertion hole, but the embodiments of the present specification are not limited thereto.

[0163] The second support portion 511b may be configured along an edge portion of the first surface of the first support portion 511a.

The second support portion 511b may be a first side wall portion, an upper side wall portion, an upper end portion, an upper skirt portion, etc., but the embodiments of the present specification are not limited thereto.

[0164] The second support 511b according to an embodiment of the present specification may include a pair of parallel straight portions 511b1 and a circumferential portion 511b2 connected between the pair of straight portions 511b1. For example, the second support 511b may include a "⊂" shape or a "U" shape in a plan view by the pair of straight portions 511b1 and the circumferential portion 511b2. For example, as shown in FIG. 8, in a top view seen along the Z-axis direction in the XYZ-axis direction, the second support 511b including the pair of straight portions 511b1 and the circumferential portion 511b2 may be "⊂" shaped. However, the embodiment of the present specification is not limited thereto.

[0165] The pair of straight portions 511b1 may have a straight shape and may be configured parallel to each other on the edge portion of the first surface of the first support portion 511a. For example, the pair of straight portions 511b1 may be configured parallel to each other along the 32nd direction (or Z direction) with the first support portion 511a therebetween, and the lower surfaces of the pair of straight portions 511b1 may be configured parallel to each other along the first direction (or X direction) with the first support portion 511a therebetween.

[0167] The first inclined surface (SS1) and the second inclined surface (SS2) may be configured to have different inclinations with respect to the vertex (VP). For example, the angle of the first inclined surface (SS1) with respect to the Z axis at the vertex (VP) may be greater than the angle of the second inclined surface (SS2) with respect to the Z axis at the vertex (VP). For example, with respect to the first surface (or front surface) of the first support portion 511a, the inclination of the second inclined surface (SS2) may be greater than the inclination of the first inclined surface (SS1). For example, the angle between the first surface (or front surface) of the first support portion 511a and the second inclined surface (SS2) may be greater than the angle between the first surface (or front surface) of the first support portion 511a and the first inclined surface (SS1).

[0168] The height of the portion of the second support 511b corresponding to the first inclined surface (SS1) can be reduced as it moves away from the second inclined surface (SS2) due to the inclination of the first inclined surface (SS1).

The circumferential portion 511b2 may have a height that is gradually lower as it moves away from the first inclined surface (SS1) of the pair of straight portions 511b1. For example, the circumferential portion 511b2 may have a height that is gradually lower as it moves away from the first inclined surface (SS1) of the pair of straight portions 511b1 so as to have the same inclination (or inclination degree) as the first inclined surface (SS1) of the pair of straight portions 511b1. For example, the first surface (or front surface) of the circumferential portion 511b2 may be configured with the same first inclined surface (SS1) as the first inclined surface (SS1) of the pair of straight portions 511b1.

[0170] The second support 511b may form a first space (SP1) on a first surface (or front surface) of the first support 511a.

For example, the one or more side holes 511f may be a third hole, a balancing hole, an air impedance adjustment hole, a third sound hole, a third sound output port, or a third sound emission part, but the embodiments of the present specification are not limited thereto.

[0183] The sound generator 513 may be supported by or coupled to the case member 511. The sound generator 513 may be arranged on the case member 511 so as to have an inverted arrangement structure with respect to the rear surface of the support member 300. For example, a part of the rear surface of the sound generator 513 may be configured to be inserted or accommodated in an accommodating hole 511h in the first support portion 511a of the case member 511.

[0184] The sound generator 513 according to an embodiment of the present specification may be configured to vibrate by a current (or voice current) applied based on Fleming's left-hand rule. For example, the sound generator 513 may include a sound generating element, a vibration generating element, a sound wave generating element, a vibration generator, a vibration source, or a sound wave generator, but the embodiments of the present specification are not limited thereto.

[0187] The magnetic circuit unit 513b may be disposed on the base frame 513a. For example, the magnetic circuit unit 513b may be configured on the base frame 513a so as to vibrate the diaphragm 513c. The magnetic circuit unit 513b may be configured to include a magnet, a bobbin, a coil, and a center pole. The magnetic circuit unit 513b may vibrate the diaphragm 513c by vibrating (or driving up and down) the bobbin by a signal applied to the coil.

[0188] The diaphragm (or acoustic diaphragm) 513c may be configured to be connected to the bobbin of the magnetic circuit unit 513b. The diaphragm 513c may output sound by vibrating due to the vibration (or up and down movement) of the bobbin.

The suspension 513d may be configured to limit the vibration distance of the bobbin by a restoring force. The suspension 513d may be configured to be coupled between the base frame 513a and the diaphragm 513c. The suspension 513d may be configured to be coupled between the base frame 513a and the second diaphragm 513c2 of the diaphragm 513c, but the embodiments of the present specification are not limited thereto. For example, the suspension 513d may be configured to be coupled between the base frame 513a and the bobbin of the magnetic circuit unit 513b.

[0191] The acoustic guide member 515 may be configured to cover the case member 511 and the acoustic generator 513. The acoustic guide member 515 may be connected or coupled to the case member 511 so as to cover the acoustic generator 513. The acoustic guide member 515 may be configured to guide the sound (or the front sound) output from the acoustic generator 513 in the vertical direction (VD) of the vibration member 100. For example, the acoustic guide member 515 may include a first surface covering the acoustic generator 513 and a second surface covering the circuit cover 200. For example, the acoustic guide member 515 may be an acoustic guider, a housing cover, a housing cover member, a housing lead (lid), or the like, but the embodiments of the present specification are not limited thereto.

[0192] The acoustic guide member 515 according to an embodiment of the present disclosure may include a guide portion on the back surface of the support member 300. For example, the guide portion may be disposed or configured on the back surface of the circuit cover 200. For example, the acoustic guide member 515 or the guide portion may include a first guide portion 515a, a second guide portion 515b, and a third guide portion 515c.

[0193] The first guide portion 515a may overlap the diaphragm 513c and have an inclined surface. For example, the first guide portion 515a may be arranged in the case member 511 and configured to cover the diaphragm 513c of the sound generator 513. For example, the first support portion 511a may be coupled to the first guide portion 515a. The first guide portion 515a may be configured to cover the first support portion 511a and the second support portion 511b of the case member 511, and the diaphragm 513c of the sound generator 513. The first guide portion 515a may be arranged in or coupled to the second support portion 511b of the case member 511. The first guide portion 515a may be arranged in or coupled to the second support portion 511b so as to be inclined. For example, the second support portion 511b may be coupled to the first guide portion 515a.

[0194] The first guide portion 515a may include a substantially rectangular shape with one side being semicircular. The first guide portion 515a may be configured to have the same or substantially the same shape as the first support portion 511a. The edge portion of the rear surface of the first guide portion 515a may be connected or coupled to the second support portion 511b of the case member 511. The edge portion of the rear surface of the first guide portion 515a may be disposed on or coupled to a first inclined surface (SS1) of a pair of straight portions 511b1 and a first surface of a circumferential portion 511b2 constituting the second support portion 511b.

[0195] The first guide part 515a may be separated from the sound generator 513 by the second support part 511b. A first space (SP1) may be formed between the first guide part 515a and the first support part 511a. The height of the first space (SP1) may gradually increase from one side of the sound generator 513 adjacent to the center of the support member 300 to the other side of the sound generator 513 adjacent to the circuit cover 200 depending on the inclination (or inclination) of the first guide part 515a. As a result, the sound output from the sound generator 513 may smoothly proceed in the direction of the other side of the sound generator 513 depending on the inclination (or inclination) of the first guide part 515a. For example, the first guide part 515a may be a first sound guide part, a first sound guide surface, a first sound adjustment surface, a first sound control surface, or a first surface, but the embodiment of the present specification is not limited thereto.

[0196] The second guide portion 515b may be configured to guide the sound generated in the first space (SP1) in the vertical direction (VD) of the vibration member. The second guide portion 515b may be configured to overlap the first support portion 511a and the tilt portion 511e of the case member 511. The second guide portion 515b may include a rectangular shape. The second guide portion 515b may be disposed on or coupled to the second inclined surface (SS2) of the pair of straight portions 511b1 constituting the second support portion 511b. Thus, the second guide portion 515b may be configured to cover a part of the first support portion 511a and the tilt portion 511e.

[0197] The second guide portion 515b may be configured to be inclined from one end of the first guide portion 515a. For example, the second guide portion 515b may be configured to be inclined from one side surface of the first guide portion 515a to the tilt portion 511e. The second guide portion 515b may be configured to be inclined at the tilt portion 511e to have a preset angle from one side surface of the first guide portion 515a. For example, the second guide portion 515b may be configured to be parallel to the tilt portion 511e. For example, the second guide portion 515b and the tilt portion 511e may be configured to have the same inclination (or inclination degree) as each other.

[0198] A first acoustic guide space (SGS1) may be formed between the second guide portion 515b and the tilt portion 511e. The first acoustic guide space (SGS1) may be formed between the inclined surfaces of the second guide portion 515b and the tilt portion 511e, which are parallel to each other. As a result, the sound generated in the first space (SP1) may be output in the vertical direction (VD) of the vibration member through the first acoustic guide space (SGS1). The sound generated in the first space (SP1) may be output in the vertical direction (VD) of the vibration member while being reflected (or diffracted) by the inclined surfaces of the second guide portion 515b that form the first acoustic guide space (SGS1). For example, the sound generated in the first space (SP1) may travel in the vertical direction (VD) of the vibration member while being reflected (or diffracted) by the inclined surfaces of the second guide portion 515b and the tilt portion 511e in the first acoustic guide space (SGS1). For example, the second guide portion 515b may be a second acoustic guide portion, a second acoustic guide surface, a second acoustic adjustment surface, a second acoustic control surface, a third surface, an inclined surface, or a tilt surface, etc., but examples herein are not limited thereto.

[0199] The second guide part 515b may overlap with the suspension 513d. The boundary part (BP) between the first guide part 515a and the second guide part 515b may overlap with the suspension 513d of the sound generator 513, or may be disposed between the suspension 513d and the circuit cover 200. The boundary part (BP) between the first guide part 515a and the second guide part 515b may be one end (or one side or part) of the second guide part 515b. For example, when the boundary part (BP) between the first guide part 515a and the second guide part 515b overlaps with the vibration plate 513c of the sound generator 513, the sound generated by the vibration of the vibration plate 513c may be reflected to the vibration plate 513c side by the second guide part 515b. Therefore, a part of the sound may be lost, or the output amount of the sound output in the vertical direction (VD) of the vibration member may be reduced. Therefore, the boundary portion (BP) between the first guide portion 515a and the second guide portion 515b may be disposed so as not to overlap with the diaphragm 513c or so as not to overlap with the diaphragm 513c of the sound generator 513.

[0200] The third guide portion 515c may be extended from the second guide portion 515b to cover the circuit cover 200. The third guide portion 515c may overlap the back surface of the support member 300 and extend from the second guide portion 515b. The third guide portion 515c may be configured to cover a part of the tilt portion 511e of the case member 511 and a part of the circuit cover 200. The third guide portion 515c may be configured to cover a part of the tilt portion 511e, the pair of extension portions 511d, and a part of the circuit cover 200. For example, the third guide portion 515c may be a third acoustic guide portion, a third acoustic guide surface, a second surface, or an acoustic output portion, but the embodiments of the present specification are not limited thereto.

[0201] The third guide portion 515c may include a rectangular shape. The third guide portion 515c may be extended from the second guide portion 515b to overlap the circuit cover 200, and may be connected or coupled to a pair of extension portions 511d of the case member 511. The third guide portion 515c may be separated from the first cover portion 211 of the circuit cover 200 by the pair of extension portions 511d. A second acoustic guide space (SGS2) may be formed between the third guide portion 515c and the circuit cover 200. The second acoustic guide space (SGS2) may be formed between the third guide portion 515c and the first cover portion 211 of the circuit cover 200, and may be connected (or communicated) with the first acoustic guide space (SGS1). The second acoustic guide space (SGS2) may be connected (or communicated) with an external space of the device. As a result, the sound generated in the first space (SP1) by the vibration (or drive) of the sound generator 513 can be output (or radiated) in the vertical direction (VD) of the vibration member 100 via the first sound guide space (SGS1) and the second sound guide space (SGS2). For example, the first cover part 211 can be a flat part, a planar part, or a sound guide surface, but the embodiment of the present specification is not limited thereto. The second sound guide space (SGS2) can be a second path, a second space, an upper space, or a front space, but the embodiment of the present specification is not limited thereto. For example, the second sound guide space (SGS2) can be an upper space, a front space, a vibration space, or a front sound space with respect to the sound generator 513, but the embodiment of the present specification is not limited thereto. For example, the second sound guide space (SGS2) can be an acoustic waveguide space (or section) of the circuit cover 200, but the embodiment of the present specification is not limited thereto.

[0202] The acoustic guide member 515 according to an embodiment of the present specification may further include a guide tip 515d. The guide tip (or acoustic guide tip) 515d may protrude from the second surface of the acoustic guide member 515 toward the circuit cover 200. The guide tip 515d may be configured at the end of the acoustic guide member 515 so as to protrude toward the circuit cover 200. The guide tip 515d may be configured to be pointed at the tip of the acoustic guide member 515. For example, the guide tip 515d may protrude from the third guide portion 515c to the rear surface of the support member 300. For example, the guide tip 515d may protrude from the tip of the third guide portion 515c to the rear surface of the support member 300.

[0203] The guide tip 515d according to an embodiment of the present specification may be configured to be pointed at the tip of the third guide portion 515c. The guide tip 515d may overlap the circuit cover 200. The guide tip 515d may overlap the second cover portion 213 of the circuit cover 200. As a result, the guide tip 515d may form an acoustic emission space on the second cover portion 213 of the circuit cover 200. The acoustic emission space may be formed between the guide tip 515d and the second cover portion 213 of the circuit cover 200. Therefore, the sound passing through the first acoustic guide space (SGS1) and the second acoustic guide space (SGS2) may be output (or radiated) in the vertical direction (VD) of the vibration member through the acoustic emission space.

[0204] The guide tip 515d can be inclined to be parallel to the second cover portion 213 of the circuit cover 200. The guide tip 515d can be inclined or tilted with the same inclination (or the same degree of inclination) as the second cover portion 213 to optimize the second acoustic guide space (SGS2) and the output angle (or radiation angle) of the sound through the second acoustic guide space (SGS2).

[0205] The acoustic guide member 515 according to an embodiment of the present disclosure may further include a fourth guide portion 515e.

[0206] The fourth guide portion 515e may be extended from the third guide portion 515c to be parallel to the second cover portion 213 of the circuit cover 200. The fourth guide portion 515e may be extended from the third guide portion 515c to cover the hole portion 217 in the circuit cover 200.

[0207] The fourth guide portion 515e and the second cover portion 213 of the circuit cover 200 may form an acoustic mixing space. The acoustic mixing space may be a space in which the sound output through the second acoustic guide space (SGS2) and the sound output through the hole portion 217 of the circuit cover 200 are mixed (or amplified). Thus, when an acoustic mixing space is further formed by the fourth guide portion 515e, the efficiency of mixing (or amplifying) the sound may be increased, and therefore the acoustic characteristics and / or sound pressure characteristics of the sound output (or radiated) in the vertical direction (VD) of the vibrating member may be further improved.

[0208] The guide tip 515d according to other embodiments of the present specification may be configured to be pointed at the tip of the fourth guide portion 515e. The guide tip 515d may be inclined to be parallel to the second cover portion 213 of the circuit cover 200. The guide tip 515d may be inclined or tilted at the same inclination (or the same degree of inclination) as the second cover portion 213 to optimize the output angle (or radiation angle) of the sound through the sound mixing space.

[0209] 8, 10, and 11, the first guide portion 515a may be disposed on the first surface (or front surface) of the second support portion 511b. Therefore, the first guide portion 515a may have the same inclination (or inclination degree) as the inclination (or inclination degree) of the first surface (or front surface) of the second support portion 511b. For example, the first guide portion 515a may have the same inclination (or inclination degree) as the first inclined surface (SS1) of the second support portion 511b. For example, the angle (or second angle) (θ2) between a horizontal line (HL) parallel to the second direction (Y) and the inner surface of the first guide portion 515a may be 170 degrees to 180 degrees, 0 degrees to 10 degrees, 175 degrees to 180 degrees, or 0 degrees to 5 degrees, but the embodiments of the present specification are not limited thereto.

[0210] The second guide portion 515b is disposed on the first surface (or front surface) of the second support portion 511b, and thus can have the same inclination (or inclination degree) as the inclination (or inclination degree) of the first surface (or front surface) of the second support portion 511b. For example, the second guide portion 515b can have the same inclination (or inclination degree) as the second inclined surface (SS2) of the second support portion 511b. For example, the angle (or third angle) (θ3) between a horizontal line (HL) parallel to the second direction (Y) and the inner surface of the second guide portion 515b can be 160 degrees to 180 degrees, 0 degrees to 20 degrees, 170 degrees to 180 degrees, or 0 degrees to 10 degrees, but the embodiments of the present specification are not limited thereto.

[0211] The angle (or fourth angle) (θ4) between the third guide portion 515c and the guide tip 515d may be the same or substantially the same as the angle (or first angle) (θ1) between the first cover portion 211 and the second cover portion 213 of the circuit cover 200 to optimize the sound output angle (or radiation angle or sound radiation angle). For example, the first angle (θ1) may ensure sound emission space (or sound emission port or emission port).

[0212] The minimum distance (or first distance) (D1) between the first guide part 515a for the first space (SP1) and the first vibration plate 513c1 of the acoustic generator 513 may be 2 mm or more and 5 mm or less (2 mm≦D1≦5 mm) or 3 mm or more and 4 mm or less (3 mm≦D1≦4 mm), but the embodiments of this specification are not limited thereto.

[0213] The distance (or second distance) (D2) between the second guide portion 515b and the tilt portion 511e for the first acoustic guide space (SGS1) may be 1 mm or more and 5 mm or less (1 mm≦D2≦5 mm) or 2 mm or more and 5 mm or less (2 mm≦D2≦5 mm), but the embodiments of this specification are not limited thereto.

[0214] The distance (or third distance) (D3) between the second guide portion 515b for the second acoustic guide space (SGS2) and the second cover portion 213 of the circuit cover 200 may be 1 mm or more and 5 mm or less (1 mm≦D1≦5 mm) or 2 mm or more and 4 mm or less (2 mm≦D1≦4 mm), but the embodiments of this specification are not limited thereto.

[0216] 7 to 10, in a device according to an embodiment of the present specification, the circuit cover 200 may be configured to include an internal space coupled (or in communication) with the second space (SP2).

[0217] The circuit cover 200 may further include a fourth cover portion 216 and a first connection hole 216a.

[0218] The fourth cover part 216 may be connected to one end (or one side or part) of the first cover part 211 adjacent to the second space (SP2). The fourth cover part 216 may be vertically connected to one end (or one side or part) of the first cover part 211 adjacent to the second space (SP2). The fourth cover part 216 may be supported by the rear part 310 of the support member 300.

[0219] The first connection hole 216a may be formed to penetrate a part of the fourth cover part 216 adjacent to the second space (SP2). The first connection hole 216a may be formed to penetrate a part of the fourth cover part 216 adjacent to the second space (SP2) along the second direction (Y). Thus, the second space (SP2) may be connected (or communicated) with the internal space of the circuit cover 200 through the first connection hole 216a. For example, the second space (SP2) may be connected (or communicated) with the internal space (or the third acoustic guide space) (SGS3) between the circuit cover 200 and the rear surface of the support member 300 through the first connection hole 216a. For example, the first connection hole 216a may be a first hole or a first cover hole, but the embodiments of the present specification are not limited thereto.

[0220] The second space (SP2) may be connected (or communicated) with the hole portion 217 through the first connection hole 216a and the internal space of the circuit cover 200. The first connection hole 216a, the internal space (SGS3) of the circuit cover 200, and the hole portion 217 may constitute an air duct of the circuit cover 200. For example, the hole portion 217 may be a hole or a cover hole, but the embodiment of the present specification is not limited thereto. As a result, the sound generated in the second space (SP2) by the vibration (or drive) of the sound generator 513 is output (or radiated) through the hole portion 217 via the first connection hole 216a and the internal space (SGS3) of the circuit cover 200, and is mixed with the sound output from the first space (SP1) through the first and second sound guide spaces (SGS1, SGS2), thereby improving the acoustic characteristics and / or sound pressure characteristics of the sound output (or radiated) in the vertical direction (VD) of the vibrating member, for example, the low-frequency band.

[0221] 7 and 8, in an apparatus according to an embodiment of the present disclosure, the circuit cover 200 may further include a second connection hole 216b.

[0222] The second connection hole 216b may be formed to penetrate a part of the fourth cover part 216 adjacent to the first connection hole 216a or the sound generating device 500. The second connection hole 216b may be formed to penetrate a part of the fourth cover part 216 along the second direction (Y). The second connection hole 216b may be formed in the fourth cover part 216 to accommodate the connection part 607 of the damping member 600.

[0223] The connecting portion 607 of the damping member 600 may be inserted (or housed) in the second connecting hole 216b and connected or coupled to an inner surface of the circuit cover 200. The connecting portion 607 may be inserted (or housed) in the second connecting hole 216b and connected or coupled to an inner surface of the first cover portion 211 of the circuit cover 200.

[0224] FIG. 12 is a diagram illustrating the acoustic output of a device according to one embodiment of the present disclosure.

[0225] Referring to FIG. 12, an apparatus according to one embodiment of the present specification can output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) of the sound generating device 500, and simultaneously output a second sound (S2) in the vertical direction (VD) of the vibrating member 100.

[0226] The first sound (S1) is generated by the vibration of the vibrating member 100 based on the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) by the vibration (or driving) of the sound generator 513 of the sound generating device 500, and may be output in the front direction (FD) of the vibrating member 100. For example, the rear sound (RSS) of the sound generator 513 may be sound output to the rear of the support member 300 or the rear of the vibrating member 100 at the rear of the sound generator 513 adjacent to or facing the support member 300. For example, the rear sound (RSS) of the sound generator 513 may be sound output from the front of the vibrating member 100 based on the vibrating member 100, or sound output in the front direction (FD) of the vibrating member 100. For example, the rear sound (RSS) of the sound generator 513 may be sound output from the sound generator 513 in the front direction (FD) of the device. For example, the rear sound (RSS) of the sound generator 513 is transmitted to the vibration member 100 through one or more openings 513o and / or holes 350 in the sound generator 513, and the vibration member 100 vibrates due to the rear sound (RSS) of the sound generator 513 and can output the first sound (S1) in the front direction (FD). For example, the first sound (S1) can include a low-frequency band, but the embodiment of the present specification is not limited thereto. For example, the first sound (S1) can include a low-frequency band of 3 kHz or less, but the embodiment of the present specification is not limited thereto.

[0227] The second sound (S2) is generated based on the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513 of the sound generating device 500, and can be output in the vertical direction (VD) of the vibrating member 100 by the guide of the sound guide member 515 configured in the sound generating device 500. For example, the front sound (FSS) of the sound generator 513 may be sound output by the vibration of the diaphragm 513c of the sound generator 513. For example, the front sound (FSS) of the sound generator 513 may be sound output in the rear direction of the vibrating member 100 based on the vibrating member 100. For example, the front sound (FSS) of the sound generator 513 may be sound output in the rear direction opposite to the front direction (FD) of the device in the sound generator 513. For example, the front sound (FSS) of the sound generator 513 may be output in the vertical direction (VD) of the vibrating member 100 as the second sound (S2) passing through the first sound guide space (SGS1) inside the sound generating device 500 and the second sound guide space (SGS2) between the sound generating device 500 and the circuit cover 200. For example, the second sound (S2) may be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100. For example, the first vertical direction (VD1) of the vibrating member 100 may be a direction from the vibrating member 100 toward the ground or a lower or upper direction of the vibrating member 100. For example, the second sound (S2) corresponding to the front sound (FSS) of the sound generator 513 may include a full range band. For example, the second sound (S2) may include a range band of 100 Hz to 20 kHz, but the embodiment of the present specification is not limited thereto.

[0228] The second sound (S2) according to an embodiment of the present specification may include a portion of the rear sound (RSS) of the sound generator 513. For example, a portion of the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) may be output in the vertical direction (VD) of the vibration member 100 as a portion of the second sound (S2) output through the internal space (SGS3) of the circuit cover 200 and the hole portion 217. By including a portion of the rear sound (RSS) of the sound generator 513, the second sound (S2) may have improved acoustic characteristics and / or sound pressure characteristics. For example, the second sound (S2) that passes through the first sound guide space (SGS1) and the second sound guide space (SGS2) and a portion of the rear sound (RSS) that is output (or radiated) through the internal space (SGS3) of the circuit cover 200 and the hole portion 217 may be combined with each other around the hole portion 217 or amplified and output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibration member 100.

[0229] According to an embodiment of the present specification, a portion of the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) may be output as the third sound (S3) in the vertical direction (VD) (or the second vertical direction (VD2)) of the vibrating member 100 through a plurality of side holes 511f in the sound generating device 500. For example, the third sound (S3) may be output in the second vertical direction (VD2) of the vibrating member 100 through a plurality of side holes 511f in the case member 511 of the sound generating device 500. For example, the second vertical direction (VD2) of the vibrating member 100 may be one or more of the upper direction and the side direction of the vibrating member 100 excluding the direction from the vibrating member 100 toward the ground, but the embodiment of the present specification is not limited thereto.

[0230] FIG. 13 is a diagram showing a device according to another embodiment of the present specification. FIG. 13 is an exploded perspective view of the circuit cover and the sound generating device shown in FIG. 7 according to another embodiment of the present specification. FIG. 14 is a cross-sectional view taken along line III-III' in FIG. 13 according to another embodiment of the present specification. FIGS. 13 and 14 show a modified configuration of the support member in the device according to one embodiment of the present specification shown in FIGS. 1 to 12. Therefore, in the following description, only the support member and the configuration related thereto will be described, and the remaining configurations will be given the same reference numerals as in FIGS. 1 to 12, and redundant description thereof will be omitted.

[0231] 13 and 14, in a device according to another embodiment of the present specification, a support member 300 may include a rear portion 310, a side portion 330, and a hole 350. The rear portion 310 and the side portion 330 are the same or substantially the same as the rear portion 310 and the side portion 330 described with reference to FIGS. 5, 6, and 9 to 12, respectively, and therefore a duplicated description thereof will be omitted.

[0232] The hole 350 may be formed in the rear part 310 of the support member 300 so as to overlap with the sound generating device 500. The hole 350 may be formed to penetrate the rear part 310 of the support member 300 so as to overlap with the sound generating device 500. The hole 350 may be formed in the rear part 310 of the support member 300 so as to overlap with the sound generating device 500. The hole 350 may be formed to penetrate the rear part 310 of the support member 300 along the third direction (Z). For example, the hole 350 may be a fourth hole, a communication hole, a connection hole, a through hole, an acoustic transmission hole, an acoustic wave transmission hole, a main hole, an air gap, an acoustic energy incidence part, or an acoustic path, but the embodiment of the present specification is not limited thereto. For example, the hole 350 may be a first hole of the support member 300.

[0233] The hole 350 may be covered by the sound generating device 500 and overlap with the sound generator 513 of the sound generating device 500. The hole 350 may have the same or substantially the same shape as the sound generator 513 of the sound generating device 500. The hole 350 may have the same or substantially the same size as the sound generator 513 of the sound generating device 500. For example, when the sound generator 513 has a circular shape, the hole 350 may have a circular shape, but the embodiments herein are not limited thereto.

[0234] The hole 350 may be disposed between the rear surface of the vibration member 100 and the sound generating device 500. The hole 350 may be disposed between the rear surface of the vibration member 100 and the sound generator 513. The hole 350 may be disposed between the backlight 130 of the vibration member 100 and the sound generator 513. For example, the hole 350 may be formed between the reflective sheet 137 of the backlight 130 and the base frame 513a of the sound generator 513. Thereby, the sound generator 513 may face the rear surface of the vibration member 100 through the hole 350 or directly face the rear surface of the vibration member 100. For example, the rear surface of the sound generator 513 may face the backlight 130 of the vibration member 100 through the hole 350 or directly face the backlight 130. For example, the base frame 513a of the sound generator 513 may face the backlight 130 through the hole 350 or directly face the backlight 130. However, the embodiments of the present specification are not limited thereto.

[0235] The sound (or rear sound) generated by the vibration (or driving) of the sound generator 513 may be directly transmitted to the vibrating member 100 through the hole 350. For example, the sound (or rear sound) generated by the vibration (or driving) of the sound generator 513 may be directly transmitted to the backlight 130 of the vibrating member 100 through the hole 350. This allows the sound (or rear sound) of the sound generator 513 to be efficiently transmitted to the vibrating member 100. Therefore, the acoustic characteristics and / or sound pressure characteristics of the first sound (S1) generated in the front direction (FD) by the vibration of the vibrating member 100 may be further improved.

[0236] The first sound (S1) is generated by the vibration of the vibrating member 100 based on the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and may be output in the front direction (FD) of the vibrating member 100. For example, the rear sound (RSS) of the sound generator 513 is transmitted to the vibrating member 100 through one or more openings 513o and holes 350 in the sound generator 513, and the vibrating member 100 vibrates due to the rear sound (RSS) of the sound generator 513 to output the first sound (S1) in the front direction (FD). For example, the rear sound (RSS) of the sound generator 513 may be sound output to the rear of the support member 300 or the rear of the vibrating member 100 at the rear of the sound generator 513 adjacent to or facing the support member 300. For example, the rear sound (RSS) of the sound generator 513 may be sound output from the front surface of the vibrating member 100 or in the front direction (FD) of the vibrating member 100, based on the vibrating member 100. For example, the rear sound (RSS) of the sound generator 513 may be sound output from the sound generator 513 in the front direction (FD) of the device. However, the embodiments of the present specification are not limited thereto.

[0237] The device according to other embodiments of the present specification may further include one or more auxiliary holes (or secondary holes) 360. The one or more auxiliary holes 360 may be formed in the support member 300 around the hole 350. The one or more auxiliary holes 360 may overlap the sound generating device 500 and be in the rear part 310 around the hole 350. The one or more auxiliary holes 360 may be formed in the rear part 310 of the support member 300 adjacent to the hole 350 so as to overlap the second space (SP2). For example, the one or more auxiliary holes 360 may be formed in the rear part 310 of the support member 300 adjacent to one side of the hole 350. For example, the one or more auxiliary holes 360 may be formed to penetrate the rear part 310 of the support member 300 corresponding to between the hole 350 and a circumferential part constituting the third support part 511c of the case member 511. The one or more auxiliary holes 360 may have a diameter of 2 mm to 5 mm, or a diameter of 3 mm to 4 mm, although embodiments herein are not limited thereto.

[0238] The one or more auxiliary holes 360 may be configured to adjust the air impedance of the second space (SP2). The one or more auxiliary holes 360 may be configured to adjust the air impedance of the second space (SP2) together with a plurality of side holes 511f formed in the third support portion 511c of the case member 511. For example, the one or more auxiliary holes 360 may be a peripheral hole, a second hole, a second balancing hole, or a second air impedance adjustment hole, but the embodiments of the present specification are not limited thereto. For example, the one or more auxiliary holes 360 may be a second hole or hole of the support member 300.

[0239] Figure 15 is another cross-sectional view taken along line III-III' in Figure 13 according to another embodiment of the present specification. Figure 15 shows a modified configuration of the sound guide member 515 of the sound generating device in the device 500 according to an embodiment of the present specification shown in Figures 13 and 14. Therefore, in the following description, only the sound guide member 515 and its related configuration will be described, and the remaining configuration will be given the same reference numerals as in Figures 13 and 14, and redundant description thereof will be omitted.

[0240] Referring to FIG. 15, an acoustic guide member 515 according to another embodiment of the present disclosure may include a first guide portion 515a and a second guide portion 515f.

[0241] The first guide portion 515a may be disposed in the case member 511 and configured to cover the diaphragm 513c of the sound generator 513. The first guide portion 515a may be disposed inclined to the case member 511 or may be coupled thereto. A first space (SP1) may be formed between the first guide portion 515a and the sound generator 513. The first guide portion 515a is the same or substantially the same as the first guide portion 515a of the sound guide member 515 described with reference to FIGS. 7 to 14, and therefore a duplicated description thereof will be omitted. For example, the first guide portion 515a may be a first sound guide portion, an inclined guide portion, a sound adjustment portion, or a sound adjustment surface, but the embodiments of the present specification are not limited thereto.

[0242] The second guide portion 515f may be extended from the first guide portion 515a to cover or overlap the circuit cover 200. The second guide portion 515f may be extended in a flat plate shape from an end of the first guide portion 515a. The second guide portion 515f may be extended from an end of the first guide portion 515a to be parallel to the first cover portion 211 of the circuit cover 200. The second guide portion 515f may be configured to cover the suspension 513d of the acoustic generator 513, the tilt portion 511e of the case member 511, and a part of the circuit cover 200. For example, the second guide portion 515f may be a second acoustic guide portion, a straight guide portion, or a linear guide portion, but the embodiments of the present specification are not limited thereto.

[0243] A first acoustic guide space (SGS1) may be formed between the second guide portion 515f and the tilt portion 511e of the case member 511, and a second acoustic guide space (SGS2) may be formed between the second guide portion 515f and the circuit cover 200. The first acoustic guide space (SGS1) may be formed between a part of the second guide portion 515f and the tilt portion 511e of the case member 511, and may be connected (or communicated) with the first space (SP1). The second acoustic guide space (SGS2) may be formed between the second guide portion 515f and the first cover portion 211 of the circuit cover 200, and may be connected (or communicated) with the first acoustic guide space (SGS1). The second acoustic guide space (SGS2) may be connected (or communicated) with an external space of the device. As a result, the sound (or front sound (FSS)) generated in the first space (SP1) by the vibration (or drive) of the sound generator 513 can be output (or radiated) in the vertical direction (VD) (or first vertical direction (VD1)) of the vibrating member via the first sound guide space (SGS1) and the second sound guide space (SGS2). For example, the front sound (FSS) of the sound generator 513 can be sound output by the vibration of the diaphragm 513c of the sound generator 513. For example, the front sound (FSS) of the sound generator 513 can be sound output in the rear direction of the vibrating member 100 based on the vibrating member 100. For example, the front sound (FSS) of the sound generator 513 can be sound output in the rear direction opposite to the front direction (FD) of the device in the sound generator 513.

[0244] The acoustic guide member 515 according to another embodiment of the present specification may further include a guide tip (or acoustic guide tip) 515d configured to be pointed at the tip of the second guide portion 515b. The guide tip 515d may overlap the circuit cover 200. The guide tip 515d may overlap the second cover portion 213 of the circuit cover 200. As a result, the guide tip 515d may form an acoustic emission space on the second cover portion 213 of the circuit cover 200. The acoustic emission space is formed between the guide tip 515d and the second cover portion 213 of the circuit cover 200, and thus, the sound passing through the first acoustic guide space (SGS1) and the second acoustic guide space (SGS2) may be output (or radiated) in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibration member through the acoustic emission space.

[0245] In another embodiment of the present specification, the sound generating device 500 can output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) of the sound generator 513, and simultaneously output a second sound (S2) in the vertical direction (VD) of the vibrating member 100.

[0246] The first sound (S1) is generated by the vibration of the vibrating member 100 based on the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and can be output in the front direction (FD) of the vibrating member 100. For example, the rear sound (RSS) of the sound generator 513 is transmitted to the vibrating member 100 through one or more openings 513o in the sound generator 513 and the hole 350 of the support member 300, and the vibrating member 100 vibrates due to the rear sound (RSS) of the sound generator 513 to output the first sound (S1) in the front direction (FD). For example, the rear sound (RSS) of the sound generator 513 can be directly transmitted to the backlight 130 of the vibrating member 100 through the hole 350 of the support member 300. This allows the sound (or rear sound) of the sound generator 513 to be efficiently transmitted to the vibrating member 100, so that the acoustic characteristics and / or sound pressure characteristics of the first sound (S1) generated by the vibration of the vibrating member 100 can be further improved.

[0247] The second sound (S2) is generated as a base by the front sound (FSS) of the sound generator 513 generated in the first space (SP1) due to the vibration (or drive) of the sound generator 513 of the sound generating device 500 causing the vibration of the diaphragm 513c, and can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 by the guide of the sound guide member 515. For example, the front sound (FSS) of the sound generator 513 can be output in the vertical direction (VD) of the vibrating member 100 as the second sound (S2) passing through the first sound guide space (SGS1) and the second sound guide space (SGS2) formed by the sound guide member 515. For example, the second sound (S2) can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100.

[0248] The second sound (S2) according to an embodiment of the present specification may include a portion of the rear sound (RSS) of the sound generator 513. For example, a portion of the rear sound (RSS) of the sound generator 513 generated in the second space (SP2) may be output in the vertical direction (VD) of the vibration member 100 as a portion of the second sound (S2) output (or radiated) through the internal space (SGS3) of the circuit cover 200 and the hole portion 217. By including a portion of the rear sound (RSS) of the sound generator 513, the second sound (S2) may have improved acoustic characteristics and / or sound pressure characteristics. For example, the second sound (S2) that passes through the first sound guide space (SGS1) and the second sound guide space (SGS2) and a portion of the rear sound (RSS) that is output (or radiated) through the internal space (SGS3) of the circuit cover 200 and the hole portion 217 may be combined with each other around the hole portion 217 or amplified and output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibration member 100.

[0249] According to one embodiment of the present specification, a portion of the rear sound (RSS) generated by the sound generator 513 in the second space (SP2) may be output as a third sound (S3) in the vertical direction (VD) (or the second vertical direction (VD2)) of the vibration member 100 through a plurality of side holes 511f in the sound generating device 500.

[0250] The acoustic guide member 515 described with reference to Fig. 15 can be applied to the acoustic guide member 515 described with reference to Fig. 7 to Fig. 12. For example, the acoustic guide member 515 described with reference to Fig. 7 to Fig. 12 can be changed to the acoustic guide member 515 described with reference to Fig. 15.

[0255] The first frame portion 513a1 may be configured to be coupled to the case member 511. The first frame portion 513a1 may include an opening (or a hollow portion). For example, the first frame portion 513a1 may have a circular ring shape or a circular band shape. The first frame portion 513a1 may be supported by the first support portion 511a of the case member 511. For example, the first frame portion 513a1 may be coupled or coupled to the first support portion 511a of the case member 511 by a coupling member. The coupling member may be an adhesive, a double-sided tape, a double-sided foam tape, a double-sided cushion tape, or a screw, but the embodiments of the present specification are not limited thereto.

[0256] The second frame portion 513a2 may be configured to overlap the opening of the first frame portion 513a1. The second frame portion 513a2 may include a receiving portion (or a recess) for receiving the magnetic circuit portion 513b. The second frame portion 513a2 may include a box shape having an opening on one side (or an upper portion).

For example, the second frame portion 513a2 may be disposed below the first frame portion 513a1.

[0257] The plurality of frame connectors 513a3 may be configured to be connected between the first frame portion 513a1 and the second frame portion 513a2. The plurality of frame connectors 513a3 may be configured to have a preset interval between the first frame portion 513a1 and the second frame portion 513a2.

Each of the plurality of frame connectors 513a3 may be configured to have an "L" shape between the first frame portion 513a1 and the second frame portion 513a2, but the embodiments of the present specification are not limited thereto.

[0259] Each of the plurality of openings 513o may be formed between the plurality of frame connecting portions 513a3. Each of the plurality of openings 513o may be formed between two adjacent frame connecting portions 513a3 among the plurality of frame connecting portions 513a3. The plurality of openings 513o may connect (or communicate) the upper space (or front space) and the lower space (or rear space) of the base frame 513a to each other.

[0260] The magnetic circuit portion 513b may be configured on the base frame 513a so as to vibrate the diaphragm 513c. The magnetic circuit portion 513b may be configured to be accommodated in the accommodation portion 513s of the base frame 513a. The magnetic circuit portion 513b may be configured to be accommodated in the accommodation portion 513s of the second frame portion 513a2.

[0261] The magnetic circuit portion 513b may be configured to include a magnet 513b1, a bobbin 513b2, a coil 513b3, and a center pole 513b4.

[0262] As shown in FIG. 16, the magnetic circuit unit 513b according to an embodiment of the present specification may have an external magnetic type (or dynamic type) structure in which the magnet 513b1 is disposed outside (or outside) the coil 513b3 (or bobbin 513b2), or an internal magnetic type structure in which the magnet 513b1 is disposed inside (or inside) the coil 513b3 (or bobbin 513b2). The internal magnetic type sound generator 513 may have an advantage of having small leakage magnetic flux and an overall small size. The sound generating device 500 may include an external magnetic type or internal magnetic type sound generator 513, but the following description will be given assuming that the sound generating device 500 includes the internal magnetic type sound generator 513.

[0263] The magnet 513b1 may be disposed (or housed) in the housing portion 513s of the base frame 513a. The magnet 513b1 may be disposed in the bottom portion 513ab of the second frame portion 513a2 configured in the base frame 513a. The magnet 513b1 may be a permanent magnet. For example, the magnet 513b1 may have a circular or disc shape. For example, the magnet 513b1 may be a magnet member, but the embodiments of the present specification are not limited thereto.

[0264] The bobbin 513b2 may be arranged (or configured) to surround the magnet 513b1. For example, the bobbin 513b2 may be arranged (or housed) in the housing portion 513s of the base frame 513a so as to surround the periphery of the magnet 513b1. For example, in a plan view, the bobbin 513b2 may be arranged so as not to overlap with the magnet 513b1. For example, the bobbin 513b2 may be arranged in the housing portion 513s around the magnet 513b1 so as to be movable (or vibrating) in the vertical direction along the thickness direction (or third direction) (Z) of the acoustic generator 513.

[0265] The bobbin 513b2 may be made of a material made of processed pulp or paper, aluminum, magnesium or alloys thereof, synthetic resin such as polypropylene, or polyamide-based fibers, but the embodiments of the present specification are not limited thereto. The bobbin 513b2 may have a circular or elliptical shape with a hollow portion, but the embodiments of the present specification are not limited thereto. The elliptical bobbin 513b2 may improve the acoustics of the high-frequency range more than the circular bobbin 513b2. Therefore, the elliptical bobbin 513b2 may have excellent heat dissipation characteristics since it generates less heat due to vibration.

[0266] The coil 513b3 may be wound around the outer circumferential surface of the bobbin 513b2. The coil 513b3 may be raised and lowered together with the bobbin 513b2. The coil 513b3 may be supplied with a signal (or current) for generating vibrations (or sound) from an external source. The coil 513b3 may be expressed as a voice coil, but the embodiments of the present specification are not limited thereto. For example, the bobbin 513b2 and the coil 513b3 may be collectively expressed as a voice coil, but the embodiments of the present specification are not limited thereto.

[0267] According to one embodiment of the present specification, when a signal is applied to the coil 513b3, the bobbin 513b2 may be vibrated in the vertical direction (Z) along the thickness direction of the acoustic generator 513 according to Fleming's left-hand rule based on the applied magnetic field formed around the coil 513b3 and the magnetic field formed around the magnet 513b1. For example, the magnetic flux generated by the magnetic field may flow along a closed loop connected to the coil 513b3, the base frame 513a, the magnet 513b1, and the coil 513b3. This allows the bobbin 513b2 to vibrate in the vertical direction (Z).

[0268] The center pole 513b4 may be disposed (or configured) on the magnet 513b1. The center pole 513b4 may be inserted (or housed) in the hollow portion of the bobbin 513b2 or surrounded by the bobbin 513b2. The center pole 513b4 may be configured in the same or substantially the same shape as the magnet 513b1. The center pole 513b4 may guide the up and down reciprocating motion of the bobbin 513b2. For example, the center pole 513b4 may be integrally formed with the magnet 513b1. For example, the center pole 513b4 may be an elevation guider or pole pieces, etc., but the embodiments of the present specification are not limited thereto.

[0269] The diaphragm 513c may be configured to be coupled to the bobbin 513b2 of the magnetic circuit unit 513b. For example, the diaphragm 513c may include a disk shape, but the embodiments of the present specification are not limited thereto. For example, the diaphragm 513c may include a plate shape having an elliptical shape. The diaphragm 513c may output sound by vibrating due to the vibration (or up and down movement) of the bobbin 513b2. For example, sound generated by the vibration of the diaphragm 513c may be output in the upper (or front) direction (FS) of the diaphragm 513c, and at the same time, may be output in the lower (or rear) direction (RS) of the diaphragm 513c through one or more openings 513o in the base frame 513a.

[0270] According to an embodiment of the present specification, the diaphragm 513c may be arranged to face the support member or to face in a direction opposite to the direction toward the support member. For example, the diaphragm 513c may be arranged to face in a direction opposite to the direction toward the support member, and may face the acoustic guide member 515 or directly face the acoustic guide member 515, as shown in FIGS. 8 to 10.

[0271] The diaphragm 513c according to an embodiment of the present specification may include a first diaphragm 513c1 and a second diaphragm 513c2. For example, the diaphragm 513c may be an acoustic generating plate or a sound wave generating plate, but the embodiment of the present specification is not limited thereto.

[0272] The first diaphragm 513c1 may be configured to be connected to the bobbin 513b2 of the magnetic circuit unit 513b. For example, the first diaphragm 513c1 may be configured at the center of the diaphragm 513c. The first diaphragm 513c1 may vibrate due to the vibration (or up and down movement) of the bobbin 513b2, thereby outputting sound. For example, the first diaphragm 513c1 may include a flat plate shape. For example, the first diaphragm 513c1 may be a main diaphragm, but the embodiments of the present specification are not limited thereto.

[0273] The second diaphragm 513c2 may be connected to the first diaphragm 513c1 and configured to surround the first diaphragm 513c. For example, the second diaphragm 513c2 may be an edge portion of the diaphragm 513c. The second diaphragm 513c2 may output sound by vibrating due to the vibration (or up and down movement) of the bobbin 513b2 or the vibration of the first diaphragm 513c1. For example, the second diaphragm 513c2 may include a flat plate shape or may include a corrugated (or bellows or wrinkled) structure. For example, the second diaphragm 513c2 may be a sub-diaphragm, a secondary diaphragm, or an auxiliary diaphragm, but the embodiments of the present specification are not limited thereto.

[0274] Each of the first diaphragm 513c1 and the second diaphragm 513c2 may be made of a material suitable for generating or outputting sound by vibration. For example, the first diaphragm 513c1 and the second diaphragm 513c2 may be made of the same material as each other, or may be made of different materials. For example, each of the first diaphragm 513c1 and the second diaphragm 513c2 may include one or more of metal, plastic, paper, fiber, cloth, leather, wood, rubber, glass, carbon, and mirror, but the embodiment of the present specification is not limited thereto.

[0275] The suspension 513d may be configured to be coupled between the base frame 513a and the diaphragm 513c. The suspension 513d may be configured to be coupled between the first frame portion 513a1 of the base frame 513a and the diaphragm 513c. The suspension 513d may be configured to be coupled between the first frame portion 513a1 of the base frame 513a and the second diaphragm 513c2 of the diaphragm 513c. The suspension 513d may be configured to adjust the vibration of the bobbin 513b2 while contracting and relaxing due to the vibration (or up and down movement) of the bobbin 513b2. The suspension 513d may be configured to limit the vibration distance of the bobbin 513b2 by a restoring force. For example, when the bobbin 513b2 vibrates more than a certain distance or vibrates less than a certain distance, the bobbin 513b2 can be restored to its original position by the restoring force of the suspension 513d. For example, the suspension 513d may include a corrugated (or bellows or wrinkled) structure between the base frame 513a and the diaphragm 513c. For example, the suspension 513d may be a damper, a spider, an edge, or the like, but the embodiments herein are not limited thereto.

[0276] The acoustic generator 513 according to an embodiment of the present disclosure may further include a protective member 513e.

[0277] The protective member 513e may be configured to protect the bobbin 513b2 from impact or prevent deformation of the bobbin 513b2 due to impact. The protective member 513e may be configured to protect the bobbin 513b2 and transmit vibration of the bobbin 513b2 to the diaphragm 513c. The protective member 513e may vibrate together with the bobbin 513b2. The protective member 513e may be disposed between the bobbin 513b2 and the diaphragm 513c. For example, the protective member 513e may be configured to increase the bonding force between the back surface of the diaphragm 513c and the bobbin 513b2. For example, the protective member 513e may be configured to prevent potential dropping or peeling of the bobbin 513b2 from the back surface of the diaphragm 513c. For example, the protective member 513e may be a ring-shaped plate member attached to the front surface of the bobbin 513b2, a disk member covering the front surface of the bobbin 513b2, or a cap member enclosing the tip of the bobbin 513b2. For example, the protective member 513e may be a bobbin protective member, an intermediate member, or a bobbin ring, but the embodiments of the present specification are not limited thereto.

One or more holes 513h may be formed to penetrate the bottom 513ab of the second frame portion 513a2. One or more holes 513h may be configured to connect or communicate the accommodation portion 513s of the second frame portion 513a2 with the lower space (or rear space) of the base frame 513a. For example, the one or more holes 513h may serve the functions of providing a heat release path through which heat generated by the driving (or vibration) of the sound generator 513 is released, increasing the sound pressure by the driving (or vibration) of the sound generator 513, and reducing the weight of the sound generator 513.

[0280] The one or more holes 513h may overlap the coil 513b3. The diameter of the one or more holes 513h may be larger than the diameter of the coil 513b3. Thus, heat generated in the coil 513b3 when the sound generator 513 vibrates may be more quickly released to the outside through the one or more holes 513h. For example, the one or more holes 513h may include any one of a circular shape, an elliptical shape, and a slit shape, but the embodiment of the present specification is not limited thereto.

The sound generator 513 may be supported on or connected to the sound guide member 515 so as to overlap with the through hole 515h. For example, the sound generator 513 may be configured to directly output sound to the protruding portion 370 of the support member 300 through the through hole 515h of the sound guide member 515. For example, the sound generator 513 may be disposed on or connected to the sound guide member 515 so as to have a forward arrangement structure opposite to the reverse arrangement structure described with reference to FIGS. 7 to 12.

[0308] The acoustic generator 513 according to one embodiment of the present specification includes the base frame 513a, the magnetic circuit part 513b, the diaphragm 513c, and the suspension 513d described with reference to Figures 16 and 17, so duplicated descriptions thereof will be omitted or simplified.

[0309] The base frame 513a of the sound generator 513 may be connected or coupled to the first guide portion 515a of the sound guide member 515 by a coupling member. For example, the first frame portion 513a1 of the base frame 513a may be connected or coupled to the first guide portion 515a of the sound guide member 515 by a coupling member, so that the sound generator 513 may have a positive arrangement structure. For example, the diaphragm 513c of the sound generator 513 may be arranged to face the support member 300. The coupling member may be an adhesive, a double-sided tape, a double-sided foam tape, a double-sided cushion tape, a bolt, or a screw, but the embodiments of the present specification are not limited thereto.

[0310] At least a portion of each of the magnetic circuit portion 513b, the diaphragm 513c, and the suspension 513d of the sound generator 513 may be accommodated or inserted in the through hole or hole 515h of the sound guide member 515. The diaphragm 513c of the sound generator 513 may face the back surface of the support member 300. The diaphragm 513c of the sound generator 513 may face or directly face the back surface portion 310 or the protruding portion 370 of the support member 300. Each of the diaphragm 513c and the suspension 513d of the sound generator 513 may face or directly face the back surface portion 310 or the protruding portion 370 of the support member 300. For example, each of the diaphragm 513c and the suspension 513d of the sound generator 513 may directly face the protruding portion 370 of the support member 300. This allows the sound (or front surface sound (FSS)) generated by the vibration of the diaphragm 513c to be output to the protrusion 370 of the support member 300, and reflected (or guided) by the protrusion 370 in the vertical direction (VD) (or first vertical direction (VD1)) of the vibration member 100, causing the protrusion 370 to vibrate.

[0311] The case member 511 according to an embodiment of the present disclosure may further include a tilt portion 511t.

[0312] The tilt portion 511t may be configured to incline from the second support portion 511j toward or away from the rear surface of the support member 300. The tilt portion 511t may be configured to incline toward the rear surface of the support member 300 to have a preset angle with respect to the second direction (Y). The tilt portion 511t may be configured to be connected between the pair of second support portions 511j and to incline toward the rear surface of the support member 300 to have a preset angle from the inner surface connecting the pair of second support portions 511j (or with respect to the second direction (Y)).

[0313] The tilt portion 511t may overlap the second guide portion 515b of the acoustic guide member 515. A first acoustic guide space (SGS1) may be formed between the tilt portion 511t and the second guide portion 515b. The first acoustic guide space (SGS1) may be formed between the tilt portion 511t and the second guide portion 515b and the rear surface of the support member 300, and may be connected (or communicated) with the first space (SP1). As a result, the tilt portion 511t may guide a part of the sound output from the acoustic generator 513 to the first space (SP1) to the second acoustic guide space (SGS2) or the vertical direction (VD) (or the first vertical direction (VD1)) of the vibration member 100.

[0314] The case member 511 according to an embodiment of the present disclosure may further include one or more side holes 511f. The case member 511 may further include a plurality of side holes 511f.

[0315] One or more side holes 511f may be configured in the first support 511i. The one or more side holes 511f may be formed to penetrate the first support 511i along the first direction (X) or the second direction (Y). The one or more side holes 511f may have a diameter of 2 mm to 5 mm or a diameter of 3 mm to 4 mm, but the embodiments of the present specification are not limited thereto.

[0316] The one or more side holes 511f may be configured to balance the air pressure in the first space (SP1) formed between the sound generator 513 and the back surface of the support member 300. For example, the one or more side holes 511f may be configured to adjust the air impedance of the first space (SP1). The one or more side holes 511f may be configured to output a part of the sound in the first space (SP1) in the vertical direction (VD) (or the second vertical direction (VD2)) of the vibration member 100. For example, the one or more side holes 511f may be configured to output a part of the sound in the first space (SP1) in the vertical direction (VD) (or the second vertical direction (VD2)) of the vibration member 100 and adjust the air impedance of the first space (SP1).

[0317] A device in another embodiment of this specification can output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) of the sound generating device 500, and simultaneously output a second sound (S2) in the vertical direction (VD) (or first vertical direction (VD1)) of the vibrating member 100.

[0318] The first sound (S1) is generated by the vibration of the protrusion 370 of the support member 300 and the vibration member 100 based on the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and may be output in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 vibrates the protrusion 370 of the support member 300 and is transmitted to the vibration member 100 through one or more holes 370h in the protrusion 270 of the support member 300, and the vibration member 100 vibrates due to the vibration of the protrusion 370 of the support member 300 and the front sound (FSS) of the sound generator 513 transmitted through one or more holes 370h, and may output the first sound (S1) in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 transmitted through the vibration of the protrusion 370 of the support member 300 and one or more holes 370h may be directly transmitted to the backlight 130 of the vibrating member 100. As a result, the sound (or the rear sound (FSS)) of the sound generator 513 can be efficiently transmitted to the vibrating member 100, so that the acoustic characteristics and / or sound pressure characteristics of the first sound (S1) generated by the vibration of the vibrating member 100 may be further improved.

[0319] The second sound (S2) is generated as a base by the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 by the guide of the sound guide member 515. For example, the front sound (FSS) of the sound generator 513 can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 as the second sound (S2) passing through the first sound guide space (SGS1) and the second sound guide space (SGS2) formed by the sound guide member 515. For example, the second sound (S2) can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100.

[0320] According to one embodiment of the present specification, a portion of the front sound (FSS) of the sound generator 513 generated in the first space (SP1) due to vibration (or driving) of the vibration plate 513c of the sound generator 513 may be output as a third sound (S3) in the vertical direction (VD) (or second vertical direction (VD2)) of the vibrating member 100 through a plurality of side holes 511f in the sound generating device 500.

[0343] The circuit cover 200 according to an embodiment of the present disclosure may further include a fourth cover portion 216 , a first connection hole 216 a , and an opening hole 218 .

[0344] The fourth cover part 216 may be connected to one end (or one side or part) of the first cover part 211 adjacent to the first space (SP1) or the first acoustic guide space (SGS1). The fourth cover part 216 may be vertically connected to one end (or one side or part) of the first cover part 211 adjacent to the first space (SP1) or the first acoustic guide space (SGS1).

[0345] The first connection hole 216a may be formed to penetrate a part of the fourth cover part 216 adjacent to the first space (SP1) or the first acoustic guide space (SGS1). The first connection hole 216a may be formed to penetrate a part of the fourth cover part 216 adjacent to the first space (SP1) or the first acoustic guide space (SGS1) along the second direction (Y). As a result, the second support part 511j and the third support part 511k of the case member 511 of the sound generating device 500 and the second guide part 515b and the third guide part 515c of the acoustic guide member 515 may be accommodated in the internal space of the circuit cover 200 through the first connection hole 216a and covered by the circuit cover 200.

[0347] A device in another embodiment of this specification can output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) of the sound generating device 500, and simultaneously output a second sound (S2) in the vertical direction (VD) (or first vertical direction (VD1)) of the vibrating member 100.

[0348] The first sound (S1) is generated by the vibration of the protrusion 370 of the support member 300 and the vibration member 100 based on the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and may be output in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 vibrates the protrusion 370 of the support member 300 and is transmitted to the vibration member 100 through one or more holes 370h in the protrusion 370 of the support member 300, and the vibration member 100 vibrates due to the vibration of the protrusion 370 of the support member 300 and the front sound (FSS) of the sound generator 513 transmitted through one or more holes 370h, and may output the first sound (S1) in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 may be sound output to the rear surface of the vibrating member 100 based on the vibrating member 100. For example, the front sound (FSS) of the sound generator 513 may be sound generated by the vibration of the diaphragm 513c and output directly to the rear surface of the support member 300. For example, the front sound (FSS) of the sound generator 513 transmitted through the vibration of the protrusion 370 of the support member 300 and one or more holes 370h may be directly transmitted to the backlight 130 of the vibrating member 100. As a result, the sound (or rear sound (FSS)) of the sound generator 513 can be efficiently transmitted to the vibrating member 100, and therefore the acoustic characteristics and / or sound pressure characteristics of the first sound (S1) generated by the vibration of the vibrating member 100 may be further improved.

[0349] The second sound (S2) is generated as a base by the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 by the guide of the sound guide member 515. For example, the front sound (FSS) of the sound generator 513 can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 as the second sound (S2) passing through the first sound guide space (SGS1) and the second sound guide space (SGS2) formed by the sound guide member 515 and the opening hole 218 of the circuit cover 200. For example, the second sound (S2) can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100.

[0350] According to one embodiment of the present specification, a portion of the front sound (FSS) of the sound generator 513 generated in the first space (SP1) due to vibration (or driving) of the vibration plate 513c of the sound generator 513 may be output as a third sound (S3) in the vertical direction (VD) (or second vertical direction (VD2)) of the vibrating member 100 through a plurality of side holes 511f in the sound generating device 500.

Therefore, in the following description, only the driving circuit unit, circuit cover, sound generating device, and related configurations will be described, and the remaining configurations will be given the same reference numerals as in FIGS. 18 to 26, and redundant description thereof will be omitted.

[0352] In devices according to other embodiments of the present specification, the driving circuit unit 170 may be disposed on the upper side (or top) (US) of the device. The printed circuit board 175 of the driving circuit unit 170 may be disposed on an edge portion of the rear surface of the upper side (or top) (US) of the support member 300. The driving circuit unit 170 is the same or substantially the same as the driving circuit unit 170 described above in connection with other embodiments of the present specification, except that it is disposed on the upper side (or top) (US) of the device, and therefore a duplicated description thereof will be omitted.

[0353] The circuit cover 200 may be arranged on the rear edge portion of the upper side (or upper portion) (US) of the support member 300, and configured to cover the driving circuit unit 170. The circuit cover 200 is the same or substantially the same as the circuit cover 200 described with reference to Figs. 18 to 26, except that it is configured to cover the driving circuit unit 170 arranged on the upper side (or upper portion) (US) of the device, and therefore a duplicated description thereof will be omitted.

[0354] The sound generating device 500 or the first sound generating device 510 and the second sound generating device 520 may be disposed on the rear surface of the lower side (or bottom) (LS) of the support member 300. The sound generating device 500 or the first sound generating device 510 and the second sound generating device 520 are the same or substantially the same as the sound generating device 500 or the first sound generating device 510 and the second sound generating device 520 described with reference to Figs. 18 to 26, except that the sound generating device 500 or the first sound generating device 510 and the second sound generating device 520 do not overlap the driving circuit unit 170 and the circuit cover 200 but overlap the rear surface of the support member 300, and therefore a duplicated description thereof will be omitted.

[0355] The support member 300 may further include an acoustic guide surface 315 that overlies the acoustic generator 500 or the first acoustic generator 510 and the second acoustic generator 520. The acoustic guide surface 315 may be configured to slope between the back portion 310 and the reinforcement portion 320 of the support member 300.

[0356] A device in another embodiment of this specification can output a first sound (S1) in the front direction (FD) of the vibrating member 100 by vibration (or driving) of the sound generating device 500, and simultaneously output a second sound (S2) in the vertical direction (VD) (or first vertical direction (VD1)) of the vibrating member 100.

[0357] The first sound (S1) is generated by the vibration of the protrusion 370 of the support member 300 and the vibration member 100 based on the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and may be output in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 vibrates the protrusion 370 of the support member 300 and is transmitted to the vibration member 100 through one or more holes 370h in the protrusion 270 of the support member 300, and the vibration member 100 vibrates due to the vibration of the protrusion 370 of the support member 300 and the front sound (FSS) of the sound generator 513 transmitted through one or more holes 370h, and may output the first sound (S1) in the front direction (FD) of the vibration member 100. For example, the front sound (FSS) of the sound generator 513 transmitted through the vibration of the protrusion 370 of the support member 300 and one or more holes 370h may be directly transmitted to the backlight 130 of the vibrating member 100. For example, the front sound (FSS) of the sound generator 513 may be sound output to the rear surface of the vibrating member 100 based on the vibrating member 100. For example, the front sound (FSS) of the sound generator 513 may be sound generated by the vibration of the diaphragm 513c and output directly to the rear surface of the support member 300. As a result, the sound (or rear sound (FSS)) of the sound generator 513 can be efficiently transmitted to the vibrating member 100, so that the acoustic characteristics and / or sound pressure characteristics of the first sound (S1) generated by the vibration of the vibrating member 100 may be further improved.

[0358] The second sound (S2) is generated as a base by the front sound (FSS) of the sound generator 513 generated in the first space (SP1) by the vibration of the diaphragm 513c due to the vibration (or drive) of the sound generator 513, and can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 by the guide of the sound guide member 515. For example, the front sound (FSS) of the sound generator 513 can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100 as the second sound (S2) passing through the first sound guide space (SGS1) and the second sound guide space (SGS2) formed by the sound guide member 515. For example, the second sound (S2) can be output in the vertical direction (VD) (or the first vertical direction (VD1)) of the vibrating member 100.

[0359] According to one embodiment of the present specification, a portion of the front sound (FSS) of the sound generator 513 generated in the first space (SP1) due to vibration (or driving) of the vibration plate 513c of the sound generator 513 may be output as a third sound (S3) in the vertical direction (VD) (or second vertical direction (VD2)) of the vibrating member 100 through a plurality of side holes 511f in the sound generating device 500.

[0361] 29, a device according to another embodiment of the present specification may be a curved device. The curved device may be a curved device, a curved display device, a curved display device, a variable display device, or a variable display device, but the embodiments of the present specification are not limited thereto.

[0362] The device according to the other embodiments of the present specification includes the vibration member 100, the support member 300, and the sound generating device described with reference to FIGS. 1 to 28, so that the duplicated description thereof will be omitted.

[0363] The rear surface of the support member 300 may be configured to include a convex or concave curved structure having a preset radius of curvature (R). The rear surface 310 of the support member 300 may be configured to include a convex or concave curved structure having a preset radius of curvature (R). For example, the distance between the rear surface 310 and the vibration member 100 may gradually increase from the center of the vibration member 100 to the edge portion.

[0364] The vibration member 100 can be recessed or bent to have a preset radius of curvature (R) by being accommodated (or inserted) in the recessed rear portion 310 of the support member 300. For example, the display panel 110 of the vibration member 300 can be curved by the curved shape of the recessed rear portion 310 of the support member 300.

[0365] A device according to another embodiment of this specification may be realized as a curved device, so that a first sound (S1) generated by driving (or vibrating) the sound generating device is output in the forward direction (FD) of the vibrating member 100, and at the same time a second sound (S2) is output in the vertical direction (VD) of the vibrating member 100, thereby increasing the viewer's sense of visual immersion and sound immersion.

For example, the upper direction (UD) of the vibrating member 100 (or device) may be a direction parallel to the short side length direction, the longitudinal direction, or the vertical direction of the device or support member 300. For example, the upper direction (UD) of the vibrating member 100 (or device) may be an upper direction opposite to the ground direction (or lower direction) (LD).

Fig. 33 shows a modified driving circuit unit, circuit cover, and sound generating device in the device described with reference to Figs. 22 to 26. Therefore, in the following description, only the driving circuit unit, circuit cover, sound generating device, and related configurations will be described, and the remaining configurations will be given the same reference numerals as Figs. 22 to 26, and redundant description thereof will be omitted.

[0377] 33, in a device according to another embodiment of the present specification, the drive circuit unit 170 and the circuit cover 200 may be disposed on the upper side (or top) (US) of the device. The drive circuit unit 170 and the circuit cover 200 are the same or substantially the same as the drive circuit unit 170 and the circuit cover 200 described with reference to FIG. 27, and therefore a duplicated description thereof will be omitted.

[0378] The sound generating device 500 or the first sound generating device 510 and the second sound generating device 520 may be disposed on the rear surface of the support member 300 so as to overlap the driving circuit unit 170 and the circuit cover 200.

[0379] The sound generating device 500, or the first sound generating device 510 and the second sound generating device 520, may be configured to output a first sound (S1) generated by vibration (or driving) of the sound generating device 500 in the front direction (FD) of the vibrating member 100, and to output a second sound (S2) different from the first sound (S1) in the upward direction (UD) of the vibrating member 100 (or device).

[0380] According to embodiments of the present specification, the device shown in FIG. 33 may be similarly applied to the curved device (or curved device, or curved display device, or curved display device, or variable display device, or variable display device) shown in FIG. 29.

[0381] Fig. 34 is a diagram showing an acoustic driving circuit unit of a device according to an embodiment of the present specification. Fig. 35 is a diagram showing acoustic paths of a first sound and a second sound output from a device according to an embodiment of the present specification.

[0382] 34 and 35, an acoustic driving circuit section 700 of an apparatus according to an embodiment of the present specification may include a signal separation circuit 710, a delay circuit 730, a mixing circuit 750, a correction circuit 770 and a driving signal generation section 790.

[0383] The signal separation circuit 710 may be configured to separate the sound source (SS) inputted under the control of the host control unit into a first sound band signal (SBS1) and a second sound band signal (SBS2). For example, the signal separation circuit 710 may be configured to separate the sound source (SS) into a first sound band signal (SBS1) and a second sound band signal (SBS2) based on a reference frequency. For example, the reference frequency may have a frequency of 1 kHz to 3 kHz, but the embodiment of the present specification is not limited thereto. For example, the signal separation circuit 710 may include a crossover circuit, but the embodiment of the present specification is not limited thereto.

[0384] The first sound band signal (SBS1) may have a frequency of 3 kHz or less. For example, the first sound band signal (SBS1) may correspond to the first sound (S1) output in the front direction (FD) of the vibrating member 100 described with reference to Figs. 1 to 17, or may correspond to a rear sound (or a sound in the opposite phase) of the sound generator.

[0385] The second sound band signal (SBS2) may have a frequency of 3 kHz or more. For example, the second sound band signal (SBS2) may correspond to the second sound (S2) output in the vertical direction (VD) of the vibrating member 100 described with reference to Figs. 1 to 17, or may correspond to a front sound (or a positive phase sound) of the sound generator.

[0386] The delay circuit 730 may be configured to delay the first sound band signal (SBS1) input from the signal separation circuit 710. By delaying the first sound band signal SBS1, the delay circuit 730 can reduce or minimize the time difference between the first sound (S1) output in the front direction (FD) of the vibrating member 100 and the second sound (S2) output in the vertical direction (VD) of the vibrating member 100.

[0387] The delay circuit 730 can delay the first sound range band signal (SBS1) based on a first distance (L1) at which a first sound (S1) output in the front direction (FD) of the vibrating member 100 reaches the ear of the user 1, a second distance (L2) at which a second sound (S2) output in the vertical direction (VD) of the device reaches the ground (G), and a third distance (L3) at which the second sound (S2) reflected from the ground (G) reaches the ear of the user 1.

[0388] According to an experimental example of the present specification, when the distance (H1) between the center of the device and the ground (G) is 200mm to 400mm and the first distance (L1) is 500mm, the third distance (L3) may be about 580mm to 590mm. For example, when the distance (H1) between the center of the device and the ground (G) is 200mm to 400mm and the first distance (L1) is 800mm, the third distance (L3) may be about 850mm to 860mm. According to an experimental example of the present specification, when the first distance (L1) is 500mm, the second sound (S2) can reach the ear of the user 1 with a delay of about 1.50μs to 1.65μs from the first sound (S1). According to another experimental example in this specification, when the first distance (L1) is 800 mm, the second sound (S2) can reach the ear of the user 1 with a delay of about 2.40 μs to 2.60 μs from the first sound (S1).

[0389] The delay circuit 730 may be configured to delay the first sound band signal (SBS1) or the first sound (S1) based on the time difference between the arrival time of the first sound (S1) at the ear of the user 1 and the arrival time of the second sound (S2) at the ear of the user 1. For example, the delay circuit 730 may be configured to delay the first sound band signal (SBS1) or the first sound (S1) within a range of 0 to 2.60 μs when the distance between the vibrating member 100, the display panel 110, and the ear of the user 1 is 850 mm to 860 mm.

[0390] The mixing circuit 750 can mix the second frequency band signal (SBS2) input from the signal separation circuit 710 and the first frequency band signal (SBS1) delayed by the delay circuit 730, and output a mixed signal.

[0391] The correction circuit 770 may extract or amplify a frequency range of the mixed signal based on a reference level to enhance the sound quality of the mixed signal or improve the flatness of the sound pressure and output the mixed signal. For example, the correction circuit 770 may amplify or attenuate the mixed signal based on a reference level for each frequency to output an acoustic correction signal. For example, the correction circuit 770 may be a parametric equalizer, but the embodiment of the present specification is not limited thereto.

[0392] The driving signal generating unit 790 may generate and output a driving signal (or a vibration driving signal or a voice signal) based on the acoustic correction signal provided from the correction circuit 770. For example, the driving signal generating unit 790 may generate and output a first driving signal and a second driving signal based on the acoustic correction signal provided from the correction circuit 770. For example, the first driving signal may be applied to the first sound generating device 510 of the sound generating device 500, and the second driving signal may be applied to the second sound generating device 520 of the sound generating device 500. Therefore, the embodiments of the present specification are not limited thereto. For example, the first driving signal may be applied to the second sound generating device 520 of the sound generating device 500, and the second driving signal may be applied to the first sound generating device 510 of the sound generating device 500.

[0393] The audio driving circuit unit 700 according to the embodiment of the present specification can improve the sound quality of the audio provided to the user 1 by delaying the first audio band signal (SBS1) or the first audio (S1) based on the time difference between the arrival time of the first audio (S1) and the arrival time of the second audio (S2) at the ear of the user 1.

[0394] FIG. 36 is a diagram showing the acoustic output characteristics of a device according to an embodiment of the present specification. FIG. 36 shows the acoustic output characteristics of the second sound depending on the inclination of the second support part by the acoustic guide member described with reference to FIGS. 7 to 12. In FIG. 36, the horizontal axis shows frequency (Hz (hertz)) and the vertical axis shows sound pressure (SPL, dB (decibels)). In FIG. 36, the solid line shows the acoustic output characteristics when the inclination of the second support part is 0 degrees. The thick solid line shows the acoustic output characteristics when the inclination of the second support part is 10 degrees.

[0395] As can be seen from FIG. 36, the thicker solid line compared to the solid line indicates that one or more of the peaks and dips are reduced in the range of approximately 3 kHz to 10 kHz, thereby reducing the maximum and minimum sound pressures and improving the flatness of the sound pressure.

[0396] Fig. 37 is a diagram showing the acoustic output characteristics of a device according to one embodiment of the present specification. Fig. 37 shows the acoustic output characteristics of the second sound due to the open structure of the hole part in the circuit cover or the sealed structure of the hole part, which have been described with reference to Figs. 7 to 12. In Fig. 37, the horizontal axis indicates frequency (Hz (hertz)) and the vertical axis indicates sound pressure level (SPL, dB (decibels)).

[0397] In Fig. 37, the thick solid line indicates the acoustic output characteristic of the second sound in a device according to an embodiment of the present specification that includes a hole in the circuit cover, and the dotted line indicates the acoustic output characteristic of the second sound in a device according to an experimental example that does not include a hole in the circuit cover.

[0398] As can be seen from FIG. 37, compared to the dotted line, the thick solid line indicates that one or more of the peaks and dips at frequencies below 3 kHz are reduced, thereby reducing the maximum and minimum sound pressures and improving the flatness of the sound pressure.
