Description

Technical Field

[0001] The present application relates to the technical field of terminal devices, and in particular to a display device. Background Art

[0002] With the continuous development of science and technology and the continuous improvement of people's living standards, users of display devices such as televisions and computers not only pursue the performance of display devices, but also have more demands on the structure and appearance of display devices, such as the thin design of display devices.

[0003] However, the thinning of display devices will limit the setting of the sound-generating device, making it difficult to take into account both the thinness of the display device and the high sound quality requirements. Utility Model Content

[0004] An object of the embodiments of the present application is to provide a display device.

[0005] The display device provided in the embodiment of the present application includes a display component, a shell component and a sound-emitting device, the display component is installed on the shell component, and the sound-emitting device is installed on the shell component: the shell component includes a back panel, a back cover, a fixing frame and a seal, the back panel is fixedly connected to the back cover, the back panel and the back cover form a cover space, at least part of the fixing frame is located in the cover space and is fixedly connected to the back panel, and the seal is fixedly connected between the fixing frame and the back panel; the display component is located on the side of the back panel facing away from the back cover; the fixing frame is provided with a connecting hole, the sound-emitting device is fixed to the fixing frame, the diaphragm of the sound-emitting device is exposed through the connecting hole, the sound-emitting device and the fixing frame, the seal and the back panel form a first cavity, and the back cavity of the sound-emitting device includes the first cavity.

[0006] In this embodiment, the shell assembly can form a cover space, which is used to accommodate the fixing frame, sound-emitting device and other components (such as electronic components) of the display device. Since the sound-emitting device and the fixing frame, the seal and the back plate can form a sealed first cavity, it is equivalent to forming a first cavity independent of the cover space. When the sound-emitting device vibrates and makes a sound, the first cavity can isolate the sound waves radiated forward by the sound-emitting device from the sound waves radiated backward, thereby avoiding the phenomenon that the sound waves radiated forward by the sound-emitting device and the sound waves radiated backward due to opposite phases cancel each other out, which is beneficial to improving the sound quality of the sound-emitting device. Among them, the sound waves radiated forward can be transmitted by the display device, thereby causing the display device to make a sound.

[0007] On the one hand, the first cavity is used to form the back cavity of the sound-emitting device. The first cavity can serve as the cavity loaded when the sound-emitting device vibrates and produces sound. The large volume of the cavity can improve the low-frequency diving performance of the sound-emitting device, thereby improving the low-frequency sound quality. In addition, the sound-emitting device uses its external back plate, fixing frame and sealing member to form its own back cavity, which makes it easy to realize a larger sound cavity design, thereby improving the sound quality of the sound emitted by the sound-emitting device. In addition, the sound-emitting device may not have a sound cavity structure or may have a smaller sound cavity structure, which is conducive to simplifying the structure of the sound-emitting device.

[0008] On the other hand, since the first cavity is a relatively independent cavity formed by the back plate, the fixing frame, the seal and the sound-emitting device, when the diaphragm of the sound-emitting device vibrates, the air in the first cavity will also vibrate. At this time, the vibration of the air in the first cavity will not interfere with the electronic components outside the first cavity, and will not affect the working condition or life of the electronic components.

[0009] Furthermore, because the mounting bracket is a cover structure mounted on the back panel, and the sound-generating device is fixed to the mounting bracket, no other fixing structure is required between the sound-generating device and the back panel. The minimum thickness of the housing assembly can be close to that of the sound-generating device, thereby facilitating a reduction in the size of the display device perpendicular to the display assembly, thus contributing to a thinner design of the display device and saving materials required to install the sound-generating device, thereby reducing costs. Furthermore, the mounting bracket has a relatively simple structure and is easily sealed to the back panel, thereby facilitating the manufacture of the housing assembly and reducing costs.

[0010] In some embodiments, the fixing frame includes a main body, the sound-generating device is fixed to the main body, and the communicating hole is located in the main body; the rear cover is provided with a mounting hole, and the main body is mounted in the mounting hole.

[0011] In this embodiment, the main body is exposed relative to the back cover, and the structure of the main body is used to fill the mounting hole of the back cover. The main body can have the same function as the back cover of the shell assembly, that is, to protect the components in the cover space of the shell assembly.

[0012] In addition, the fixing frame is used to fix the main body of the sound-emitting device so that it is exposed relative to the back cover. There is no fixing structure of other shell components between the main body and the back cover, which reduces the space occupied by the shell component in the thickness direction of the display device, further reduces the thickness of the display device, is conducive to the thin setting of the display device, or is conducive to increasing the volume of the first cavity to improve the sound quality of the bass.

[0013] In some embodiments, the main body includes a first surface disposed away from the display assembly, the back cover includes a second surface disposed away from the display assembly, and the first surface is flush with the second surface.

[0014] In this embodiment, the main body protrudes toward the back panel until it is flush with the back panel, thereby maximizing the use of the thickness space in the thickness direction of the display device, which is conducive to setting a larger first cavity or making the display device have a thinner size; in addition, the first surface and the second surface can roughly form a surface, making the back structure of the display device more regular.

[0015] In some embodiments, the entire fixing frame is located on a side of the rear cover close to the back plate; the rear cover also has a sound outlet, and the diaphragm of the sound-emitting device faces the sound outlet.

[0016] In this embodiment, since the sound-generating device is fixed to the mounting bracket, with the diaphragm facing the sound outlet, the sound-generating device is essentially located entirely within the housing space. Furthermore, since the mounting bracket is fixed to the back panel, with the main body positioned between the back panel and the rear cover, the mounting bracket is essentially located entirely within the housing space. As a result, the housing assembly can protect both the sound-generating device and the mounting bracket, preventing collisions and interference from outside the housing assembly. Furthermore, the diaphragm is positioned toward the sound outlet, which also facilitates direct sound output from the sound-generating device.

[0017] In some embodiments, the housing assembly further includes a vibration isolator, which is elastic, connected between the fixing frame and the rear cover, and disposed around the communicating hole.

[0018] In this embodiment, the vibration isolator has the function of isolating and reducing vibration. Since the sound-emitting device is installed on the fixed frame, if the sound-emitting device vibrates, it will drive the fixed frame to vibrate slightly. Through the isolation of the vibration isolator, the vibration of the fixed frame is reduced and transmitted to the back cover, thereby avoiding vibration and abnormal noise of the display device caused by the sound-emitting device.

[0019] In some embodiments, the back plate includes a raised portion, which is raised toward a side away from the display assembly. The raised portion is annular and is fixedly connected to the fixing frame.

[0020] In this embodiment, the raised portion is provided in an annular, protruding configuration, thereby providing a localized thickening of the backplate. This means that the raised portion reinforces the backplate's structure, thereby improving the backplate's support capabilities, thereby contributing to greater strength and deformation resistance of the display device. Furthermore, the raised portion can be raised to a certain height, and the raised portion and the fixed portion can be connected via a sealing member. When a large gap exists between the fixing frame and the first portion, a thinner seal can still connect the fixing frame and the backplate, facilitating a thinner seal and reducing the cost of the seal.

[0021] In some embodiments, the fixing frame includes a fixing portion, a connecting portion and a main body portion, the connecting portion is connected between the fixing portion and the main body portion, the connecting portion surrounds the main body portion and protrudes toward the back plate, the fixing portion is fixed to the back plate, and the sound-emitting device is fixed to the main body portion; the raised portion is fixedly connected to the fixing portion through a sealing member.

[0022] In this embodiment, the shape of the raised portion easily matches the shape of the seal and the fixed portion. The raised portion facilitates positioning of the seal and the fixed portion, facilitating assembly. Furthermore, because the raised portion is relatively strong, the fixed portion also has relatively high strength. The elastic seal, connected between the raised portion and the fixed portion, further facilitates the seal's ability to cushion vibrations between the fixed portion and the raised portion, thereby reducing the risk of resonant noise. The high strength of the raised portion reinforces the backplate, preventing deformation. This allows for better alignment between the raised portion and the fixed portion, minimizing air leakage caused by deformation-induced poor sealing of the seal. This helps maintain high sound quality and improves reliability for the sound-generating device. Furthermore, because the raised portion can be raised to a certain height and can be connected to the fixed portion via the seal, even when the fixed portion is spaced significantly apart from the first portion, a thinner seal can still connect the fixed portion and the backplate, facilitating a thinner seal design and reducing the cost of the seal.

[0023] In some embodiments, the back plate is an integrally formed structural member, and / or the fixing frame is an integrally formed structural member.

[0024] In this embodiment, when the back plate can be an integrally formed structural member, the back plate has good mechanical properties and can provide good support capabilities for the components inside the housing assembly.

[0025] When the fixing frame is an integrally formed structural member, the fixing frame can provide more reliable support for the sound-generating device and can reduce the possibility of noise generated by resonance with the sound-generating device, thereby helping to improve the sound quality of the display device.

[0026] In some embodiments, the seal is elastic.

[0027] In this embodiment, the sealing member is equivalent to an elastic connection between the back plate and the fixing frame. Since the sound-generating device is installed on the fixing frame, when the sound-generating device vibrates and makes a sound, the sound-generating device may transmit the vibration to the fixing frame. Since the sealing member can perform vibration isolation, the vibration of the fixing frame is prevented from being transmitted to the back plate, thereby reducing the formation of resonance noise.

[0028] In some embodiments, the sealing member is made of foam or rubber.

[0029] In some embodiments, the housing assembly further includes a fastener and an elastic member, the elastic member is fixed to the fixing frame, and the fastener fixedly connects the elastic member and the back plate.

[0030] In this embodiment, the fasteners and the elastic member can improve the reliability of the connection between the fixing frame and the back plate, and since the elastic member can elastically connect and buffer between the fixing frame and the fastener, when the sound-emitting device vibrates and makes a sound, the elastic member can prevent the fixing frame from transmitting the vibration or impact to the back plate, thereby reducing the formation of resonance noise.

[0031] In some embodiments, the diaphragm of the sound-generating device is located in the communicating hole.

[0032] In this embodiment, because the diaphragm is exposed through the communication hole and the diaphragm of the sound-generating device is located in the communication hole, most of the other components of the sound-generating device are located inside the fixing frame. The space occupied by the sound-generating device in the thickness direction of the display device overlaps with the space occupied by the fixing frame in the thickness direction of the display device. The sound-generating device does not occupy additional space in the thickness direction of the display device. By fully utilizing the space between the fixing frame and the back plate, the thin design of the display device is facilitated. Furthermore, because the diaphragm is located in the communication hole, the sound-generating device effectively blocks the communication hole with its own structure.

[0033] In some embodiments, the vibration direction of the diaphragm is perpendicular to the display assembly.

[0034] In this embodiment, the thickness of the sound-generating device can be easily designed to be smaller than its height and width. The thickness direction of the sound-generating device, which has a smaller dimension, is aligned with the thickness direction of the display device. Therefore, the size of the sound-generating device imposes less restriction on the thickness of the display device, facilitating a thinner design for the display device.

[0035] In some embodiments, the sound-emitting device further includes a basin, a voice coil, and a magnetic circuit assembly; the basin is mounted on a fixed frame; the diaphragm is fixed to the basin; the magnetic circuit assembly is fixed to the basin and arranged opposite to the diaphragm, and the magnetic circuit assembly has a magnetic gap; one end of the voice coil is fixed to the diaphragm, and the other end is located in the magnetic gap of the magnetic circuit assembly.

[0036] In this embodiment, the sound-emitting device can be assembled and installed as a whole on a fixed frame. The space on one side of the diaphragm of the sound-emitting device is connected to the outer space of the display device through the sound outlet hole so that the sound-emitting device can produce sound. The space on the other side of the diaphragm is connected to the first cavity to improve the sound quality of the sound-emitting device. The sound-emitting device itself does not need to form a large sound cavity, and the structure of the sound-emitting device is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees.

[0049] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated.

[0050] The display device provided in this application can be a television, an ultra-mobile personal computer (UMPC), a personal digital assistant (PDA), a tablet computer (pad), a notebook computer, and a vehicle-mounted display device, etc. The embodiments of this application do not strictly limit the specific form of the above-mentioned display device.

[0051] For example, the display device may have a larger screen size so that the display device can provide a larger image. For example, the screen size of the display device may be greater than or equal to 14 inches. For example, the display device may be a 50-inch TV or a larger TV or screen.

[0052] Please refer to Figures 1 to 3 , Figure 1 is a front view of a display device 100 provided in an embodiment of the present application. Figure 2 yes Figure 1 The three-dimensional structure schematic diagram of the display device 100 is shown. Figure 3 yes Figure 2 The illustrated diagram is a schematic diagram of the exploded structure of the display device 100 in some embodiments.

[0053] Figure 1 The display device 100 in the embodiment is described illustratively by taking a television as an example.

[0054] In some embodiments, the display device 100 may include a display assembly 10 and a housing assembly 20. The display assembly 10 is mounted on the housing assembly 20. The display device 100 may have a thickness direction, a length direction, and a height direction. The thickness direction, length direction, and height direction of the display device 100 are perpendicular to each other. The thickness direction of the display device 100 may be perpendicular to the display assembly 10 (display screen). The thickness direction of the display device 100 may be the Z direction, the length direction of the display device 100 may be the X direction, and the height direction of the display device 100 may be the Y direction.

[0055] For example, the display assembly 10 may include a display screen, a light emitting element, a reflector, and a light diffuser, wherein the display screen, the light diffuser, and the reflector are arranged in sequence, with the light diffuser connected between the display screen and the reflector, and the light emitting element located between the light diffuser and the reflector.

[0056] The display screen may be a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) display panel, or a quantum dot light-emitting diode (QLED) display panel. The display screen may be a flat screen. In other embodiments, the display screen may be a curved screen, for example, a concave curved surface.

[0057] The reflector is used to reflect the light from the point light source onto the diffuser above. The reflector can effectively increase the light intensity of the outgoing light entering the diffuser, thereby increasing the utilization rate of the light.

[0058] The light-emitting element may be composed of a plurality of point light sources, which may be arranged in a matrix, and the point light sources may be light-emitting diodes (LEDs).

[0059] The light emitted by the light emitting element can pass directly through the light diffuser or be reflected by the reflector before passing through the light diffuser. This allows the light diffuser to emit uniform white light toward the display screen, effectively forming a uniform surface light source. The light emitted by the light diffuser then passes through the display screen and exits, forming an image on the display screen, thereby achieving the display function of the display device 100.

[0060] In some embodiments, the display assembly 10 may further include a membrane (not shown). The membrane may be positioned between the diffuser and the display screen. The membrane is an optical membrane used to process light. For example, the membrane may include a brightness enhancement film to increase the brightness of the display screen within a viewing angle. The membrane may also include a diffusion film, which can more evenly mix the light source, resulting in a more uniform brightness on the display screen.

[0061] Exemplarily, the housing assembly 20 may include a back plate 1 and a back cover 2. The back cover 2 is detachably connected to the back plate 1. The display assembly 10 may be located on a side of the back plate 1 facing away from the back cover 2.

[0062] The back plate 1 can be a generally rectangular, flat structural member. The back plate 1 can be fixedly connected to the display assembly 10 to support the display assembly 10. The back plate 1 can be a thin plate to reduce the thickness of the display device 100. The back plate 1 can have high strength to provide better support for the display assembly 10.

[0063] For example, the material used for the back panel 1 may include but is not limited to at least one of aluminum alloy plate, stainless steel plate, steel-plastic plate, injection-molded plastic, extruded plastic, iron plate, etc., and can be specifically set according to needs.

[0064] The back panel 1 can be an integrally formed structural member. In this case, the back panel 1 has good mechanical properties and can provide good support for the components inside the housing assembly 20. In other embodiments, the back panel 1 can also be a split structure, for example, the back panel 1 can be assembled from a plate body and a midframe.

[0065] The back cover 2 may be a substantially hood structure. The back cover 2 may be a thin plate. The back cover 2 is used to be fixedly connected to the back plate 1. The back cover 2 may have high strength to provide good support for the back plate 1 and other components.

[0066] For example, the material used for the back cover 2 may include but is not limited to at least one of aluminum alloy plate, stainless steel plate, steel-plastic plate, injection-molded plastic, extruded plastic, iron plate, etc., and can be specifically set according to needs.

[0067] The rear cover 2 may be an integrated structural component, and in this case the rear cover 2 has better mechanical properties.

[0068] See also Figure 4 , Figure 4 yes Figure 1 The illustrated diagram is a simplified schematic diagram of the internal structure of the display device 100 in some embodiments.

[0069] In some embodiments, the display device 100 may further include a sound-generating device 30. The sound-generating device 30 is used to realize the sound-generating function of the display device 100. The sound-generating device 30 may be mounted on the housing assembly 20. The sound-generating device 30 may have a thickness direction, a length direction, and a height direction. The thickness direction, length direction, and height direction of the sound-generating device 30 are perpendicular to each other.

[0070] Exemplarily, the sound-emitting device 30 may have a diaphragm 301, and the diaphragm 301 of the sound-emitting device 30 may produce sound by pushing air to vibrate. The sound-emitting device 30 may be installed on the inner side of the shell assembly 20 and communicate with the outer space of the shell assembly 20 so that the sound can be transmitted to the outside of the shell assembly 20. For example, the shell assembly 20 may be provided with a sound outlet 201, and the sound-emitting device 30 emits sound to the outside of the shell assembly 20 through the sound outlet 201. The sound-emitting device 30 may be located in the middle of the back cover 2 or at the periphery of the back cover 2, which is not strictly limited here. The number of sound-emitting devices 30 may be one or more. For example, when the number of sound-emitting devices 30 is more than one, the multiple sound-emitting devices 30 may be arranged at intervals and may be symmetrically distributed on the shell device so that the display device 100 has better sound quality.

[0071] It is understandable that when the sound-generating device 30 can vibrate and generate sound, when the sound-generating device 30 is connected to alternating current with different characteristics (such as frequency and voltage), it can generate sound at the corresponding frequency and loudness, thereby generating the desired sound.

[0072] It is understandable that the display device 100 may further include electronic components (not shown). The electronic components may include circuit boards, functional interfaces, etc. The circuit boards may have controllers, etc. The specific types and quantities of components included in the electronic device can be set according to needs and are not strictly limited in this embodiment. Among them, the electronic components can be electrically connected to the display component 10, so that the display component 10 displays the corresponding picture. The electronic device can be electrically connected to the sound device 30, so that the sound device 30 emits the corresponding sound.

[0073] It is understood that the back cover 2 may be provided with a variety of through-holes. For example, the through-holes may serve as external mounting holes, through which an external bracket may be mounted to support the display device 100. Alternatively, the display device 100 may be directly suspended through the external mounting holes. For example, the through-holes may serve as clearance holes to allow for the functional interfaces of electronic components to be avoided. For example, the through-holes may also serve as heat dissipation holes, etc. Examples are not given one by one in this embodiment.

[0074] In some embodiments, the housing assembly 20 may further include a fixing bracket 3. The rear cover 2 and the back plate 1 may enclose a housing space 20a, and the fixing bracket 3 may be mounted on the back plate 1 and located within the housing space 20a.

[0075] The housing space 20a can be used to house components of the display device 100, such as electronic components and a sound-generating device 30, which are not listed in detail in this example. The back panel 1 can support the components within the housing space 20a, and the back cover 2 can protect the components within the housing space 20a.

[0076] The fixing frame 3 may be roughly in the form of a cover structure.

[0077] Exemplarily, the fixing frame 3 may include a fixing portion 31, a connecting portion 32, and a main body 33. The connecting portion 32 is connected between the fixing portion 31 and the main body 33. The connecting portion 32 is arranged around the main body 33. The fixing portion 31 is arranged around the connecting portion 32. The connecting portion 32 is arranged to protrude toward one side of the main body 33, and the fixing portion 31 is arranged around the main body 33. For example, the fixing portion 31 and the main body 33 can each be a roughly flat plate structure. For example, the fixing portion 31 and the main body 33 can each be a roughly rectangular ring structure, and the connecting portion 32 can be a roughly rectangular cylindrical structure.

[0078] For example, the fixing frame 3 may have a communication hole 34, which may be located in the middle of the main body 33 and extend through the main body 33. The fixing frame 3 may have a fixing hole 35, which may be located in the fixing portion 31. The fixing holes 35 may be multiple, and the multiple fixing holes 35 may be arranged along the circumference of the fixing portion 31. The cover space 20a of the fixing frame 3 may have an opening, which may be formed in the connecting portion 32.

[0079] Exemplarily, the fixing frame 3 may be an integrally formed structural component.

[0080] For example, the fixing frame 3 can be a thin plate. The fixing frame 3 can be formed by stamping a metal plate or using plastic injection molding. The integrally formed fixing frame 3 has good integrity and better supporting capacity.

[0081] Exemplarily, the fixing frame 3 may be fixedly mounted on the back plate 1 , and the fixing frame 3 and the back plate 1 of the housing assembly 20 may enclose a first cavity 20 b .

[0082] For example, the shell assembly 20 may also include a fastener 4 and an elastic member 5. The elastic member 5 is fixed to the fixing frame 3, and the fastener 4 fixedly connects the elastic member 5 and the back plate 1. At this time, the back plate 1 is relatively fixed to the fastener 4, and the fastener 4 is elastically connected to the fixing frame 3. Among them, the back plate 1 can be initially provided with a fastening hole 11, and the position and number of the fastening hole 11 can be set corresponding to the position and number of the fixing hole 35, so that the fastening hole 11 and the fixing hole 35 can be docked. Among them, the elastic member 5 can be roughly annular in structure, and the elastic member 5 can be fixed to the fixing hole 35. The fastening hole 11 and the fixing hole 35 can be set in a one-to-one correspondence. Among them, the fastener 4 can be a bolt, the fastener 4 can be threadedly connected to the fastening hole 11, the fastener 4 can be passed through the elastic member 5, and fixedly connected to the elastic member 5, so that the fixing frame 3 is fixed to the back plate 1.

[0083] For example, the communication hole 34 of the fixing frame 3 may be in communication with the sound outlet 201 of the housing assembly 20. For example, the sound outlet 201 may include a plurality of sound outlet holes with smaller diameters, and the plurality of sound outlet holes may be arranged in an array.

[0084] The fixing frame 3 and the back plate 1 can be sealed. The housing assembly 20 can include a seal 6. The seal 6 is fixed between the back plate 1 and the fixing frame 3 of the housing assembly 20 to seal the space between the back plate 1 and the fixing frame 3.

[0085] For example, the seal 6 can be an annular structure, and its shape corresponds to the shape of the opening of the fixing frame 3. The seal 6 is located at the opening of the fixing frame 3, thereby sealing the opening of the fixing frame 3 through the back plate 1. The fastener 4 can apply a tightening force to abut the fixing frame 3, the seal 6, and the back plate 1, thereby ensuring a more reliable sealing connection between the fixing frame 3 and the back plate 1.

[0086] For example, the seal 6 can be made of a flexible material or elastic material; for example, the seal 6 can be made of foam, rubber, etc. A gap can be provided between the fixing frame 3 and the back plate 1 to accommodate the seal 6, thereby ensuring a good seal between the fixing frame 3 and the back plate 1.

[0087] In some other embodiments, the fixing frame 3 and the housing assembly 20 may also be sealed together by means of sealant or the like.

[0088] The sound-generating device 30 can be mounted on the fixing frame 3. The first cavity 20b is used to form a sound cavity of the sound-generating device 30, and the sound-generating device 30 generates sound through the sound outlet 201. The diaphragm 301 of the sound-generating device 30 is exposed through the connecting hole 34, so that the sound-generating device 30 can generate sound.

[0089] Exemplarily, the sound-emitting device 30 can be located on the side of the fixing frame 3 facing the back plate 1, that is, the sound-emitting device 30 can be located on the inner side of the fixing frame 3. The sound-emitting device 30 can be fixed on the peripheral side wall of the connecting hole 34. The sound-emitting device 30, the fixing frame 3, the sealing member 6, and the back plate 1 enclose a first cavity 20b, and the rear cavity of the sound-emitting device 30 includes the first cavity 20b. That is, the first cavity 20b can be used to form the rear cavity of the sound-emitting device 30 to improve the sound quality of the sound-emitting device 30 when it emits sound. It is understandable that part of the space of the sound-emitting device 30 itself can also be used to form its rear cavity. It is understandable that the space on one side of the diaphragm 301 of the sound-emitting device 30 is connected to the sound outlet 201, and this side space is the front cavity; the space on the other side of the diaphragm 301 of the sound-emitting device 30 includes the first cavity 20b, and this side space is the rear cavity.

[0090] For example, the diaphragm 301 of the sound-emitting device 30 can be located in the connecting hole 34. When the sound-emitting device 30 vibrates to produce sound, the vibrating part of the diaphragm 301 can be located in the connecting hole 34. The diaphragm 301 of the sound-emitting device 30 can be roughly flush with the connecting hole 34. At this time, since the diaphragm 301 is exposed through the connecting hole 34 and the diaphragm 301 of the sound-emitting device 30 is located in the connecting hole 34, most of the other components of the sound-emitting device 30 (such as the basin frame, magnetic circuit assembly, voice coil, etc. shown later) are located on the inner side of the fixing frame 3. The space occupied by the sound-emitting device 30 in the thickness direction (Z direction) of the display device 100 overlaps with the space occupied by the fixing frame 3 in the thickness direction of the display device 100. The sound-emitting device 30 does not occupy additional space in the thickness direction of the display device 100. By making full use of the space between the fixing frame 3 and the back panel 1, it is beneficial to the thin design of the display device 100. Furthermore, the diaphragm 301 is located in the communication hole 34 , and the sound-generating device 30 is equivalent to blocking the communication hole 34 by using its own structure.

[0091] In some other embodiments, the sound generating device 30 may also be partially located on the side of the fixing frame 3 facing away from the back plate 1 .

[0092] In this embodiment, the shell assembly 20 can form a cover space 20a, which is used to accommodate the fixing frame 3, the sound-emitting device 30 and other components (such as electronic components) of the display device 100. Since the sound-emitting device 30 and the fixing frame 3, the seal 6 and the back plate 1 can form a sealed first cavity 20b, it is equivalent to forming an independent first cavity 20b in the cover space 20a. When the sound-emitting device 30 vibrates and makes a sound, the first cavity 20b can isolate the sound waves radiated forward by the sound-emitting device 30 from the sound waves radiated backward, avoiding the phenomenon that the sound waves radiated forward by the sound-emitting device 30 and the sound waves radiated backward by the sound-emitting device 30 cancel each other out due to opposite phases, which is beneficial to improving the sound quality of the sound-emitting device 30. Among them, the sound waves radiated forward can be transmitted by the display device 100, thereby causing the display device 100 to make a sound.

[0093] On the one hand, the first cavity 20b is used to form the back cavity of the sound-generating device 30. The first cavity 20b can serve as the cavity that the sound-generating device 30 bears when vibrating and producing sound. This cavity has a large volume, which can improve the low-frequency diving performance of the sound-generating device 30, thereby improving the low-frequency sound quality. In addition, the sound-generating device 30 can use its external back plate 1, fixing frame 3, and sealing member 6 to form its own back cavity, which facilitates the design of a larger sound cavity, thereby improving the sound quality of the sound generated by the sound-generating device 30. In addition, the sound-generating device 30 can have no sound cavity structure or can have a smaller sound cavity structure, which helps to simplify the structure of the sound-generating device 30.

[0094] On the other hand, since the first cavity 20b is a relatively independent cavity formed by the back plate 1, the fixing frame 3, the seal 6 and the sound-emitting device 30, when the diaphragm 301 of the sound-emitting device 30 vibrates, the air in the first cavity 20b will also vibrate. At this time, the vibration of the air in the first cavity 20b will not interfere with the electronic components outside the first cavity 20b, and will not affect the working condition or life of the electronic components.

[0095] Furthermore, because the fixing frame 3 is a cover structure that covers the back plate 1, and the sound-generating device 30 is fixed to the fixing frame 3, there is no need for any other fixing structure between the sound-generating device 30 and the back plate 1. The minimum thickness of the housing assembly 20 can be close to the thickness of the sound-generating device 30, which is beneficial for reducing the size of the display device 100 in the direction perpendicular to the display assembly 10, that is, facilitating a thin design of the display device 100, and also helps save materials required for installing the sound-generating device 30, thereby reducing costs. In addition, the fixing frame 3 has a relatively simple structure and is easy to achieve a sealed connection with the back plate 1, thus facilitating the manufacture of the housing assembly 20 and reducing costs.

[0096] In some embodiments, as described above, when the fixing frame 3 is an integrally formed structural member, the sound-generating device 30 is mounted on the fixing frame 3. In this case, the fixing frame 3 can provide relatively reliable support for the sound-generating device 30 and reduce the possibility of noise generated by resonance with the sound-generating device 30, thereby improving the sound quality of the display device 100.

[0097] In some embodiments, as described above, when the seal 6 is elastic, the seal 6 is equivalent to elastically connecting the back plate 1 and the fixing frame 3. Since the sound-generating device 30 is installed on the fixing frame 3, when the sound-generating device 30 vibrates and makes a sound, the sound-generating device 30 may transmit the vibration to the fixing frame 3. Since the seal 6 can perform vibration isolation, the vibration of the fixing frame 3 is prevented from being transmitted to the back plate 1, thereby reducing the formation of resonance noise.

[0098] Furthermore, when the fixing frame 3 and the back panel 1 are also connected by the fastener 4 and the elastic member 5, the fastener 4 and the elastic member 5 can improve the reliability of the connection between the fixing frame 3 and the back panel 1. Moreover, since the elastic member 5 can elastically connect and buffer between the fixing frame 3 and the fastener 4, when the sound-generating device 30 vibrates and makes a sound, the elastic member 5 can prevent the fixing frame 3 from transmitting the vibration or impact to the back panel 1, thereby reducing the formation of resonance noise.

[0099] In some embodiments, the vibration direction of the diaphragm 301 may be perpendicular to the display assembly 10 .

[0100] The thickness direction of the sound-generating device 30 is generally parallel to the vibration direction of the diaphragm 301. Compared to the height and width of the sound-generating device 30, the thickness of the sound-generating device 30 can be easily designed to be smaller. The direction perpendicular to the display assembly 10 is also the thickness direction of the display device 100. Therefore, the thickness direction of the sound-generating device 30 is equivalent to being parallel to the thickness direction (Z direction) of the display device 100.

[0101] In this embodiment, the thickness direction of the smaller size of the sound-generating device 30 is the same as the thickness direction of the display device 100 , so the size of the sound-generating device 30 has less restriction on the thickness of the display device 100 , which is conducive to the thin design of the display device 100 .

[0102] In some examples, the projected area of ​​the first cavity 20b in the thickness direction of the display device 100 is greater than twice the projected area of ​​the sound-emitting device 30. In this case, the volume of the first cavity 20b is greater than the volume of the sound-emitting device 30, and the sound-emitting device 30 has a larger sound cavity, which greatly improves the sound quality of the sound-emitting device 30, thereby improving the sound quality of the display device 100.

[0103] In some embodiments, the entire mounting bracket 3 can be located on the side of the rear cover 2 near the back panel 1, with the diaphragm 301 of the sound-emitting device 30 positioned toward the sound outlet 201. In this case, since the sound-emitting device 30 is fixed to the mounting bracket, with the diaphragm 301 facing the sound outlet 201, the sound-emitting device 30 is essentially located entirely within the housing space 20a. Since the mounting bracket 3 is fixed to the back panel 1, with the main body 33 positioned between the back panel 1 and the rear cover 2, the mounting bracket 3 is essentially located entirely within the housing space 20a. Consequently, the housing assembly 20 can protect both the sound-emitting device 30 and the mounting bracket 3, preventing collisions and interference from outside the housing assembly 20. Furthermore, the positioning of the diaphragm 301 toward the sound outlet 201 also facilitates direct sound emission from the sound-emitting device 30.

[0104] In some embodiments, the housing assembly 20 may further include a vibration isolator 7. The vibration isolator 7 is disposed between the mounting bracket 3 and the back cover 2, connecting the mounting bracket 3 and the back cover 2. The vibration isolator 7 surrounds the communication hole 34 and may also surround the sound outlet 201. For example, in the thickness direction of the display device 100, the projection of the vibration isolator 7 surrounds the projection of the sound-emitting device 30.

[0105] For example, the mounting bracket 3 and the back cover 2 can be spaced apart and isolated from each other by a vibration isolator 7. The vibration isolator 7 can be a rectangular ring structure to better fit the mounting bracket 3. The vibration isolator 7 can be elastic to achieve a vibration isolation effect. For example, the vibration isolator 7 can be made of foam, rubber, or other materials.

[0106] For example, in a direction perpendicular to the display assembly 10, the communication hole 34 of the fixing bracket 3 is arranged opposite the sound outlet 201 of the back cover 2. The sound outlet 201 is equivalent to being located on the back of the display device 100, and the communication hole 34 is arranged toward the sound outlet 201. For example, the sound outlet 201 and the communication hole 34 can be circular. The diameter of the sound outlet 201 can be approximately the same as the diameter of the communication hole 34. The vibration isolator 7 can also have a circular structure, and the diameter of the vibration isolator 7 can be larger than the diameter of the communication hole 34.

[0107] In this embodiment, the vibration isolator 7 has the function of isolating and reducing vibration. Since the sound-emitting device 30 is installed on the fixing frame 3, if the sound-emitting device 30 vibrates, it will drive the fixing frame 3 to vibrate slightly. Through the isolation of the vibration isolator 7, the vibration of the fixing frame 3 is reduced and transmitted to the back cover 2, thereby avoiding the vibration and abnormal sound of the display device 100 caused by the sound-emitting device 30.

[0108] In addition, when the entire fixing frame 3 can be located on the side of the back cover 2 close to the back plate 1, the vibration isolation member 7 can also form a sound outlet channel between the connecting hole 34 and the sound outlet hole 201. The vibration isolation member 7 can prevent the connecting hole 34 and / or the sound outlet hole 201 from being connected to other cavities in the shell assembly 20, so that the sound emitted by the sound-emitting device 30 can be directly output from the sound outlet channel, which is beneficial to improving the sound quality.

[0109] In some embodiments, the sound-generating device 30 may include, in addition to the diaphragm 301 , a basket 302 , a voice coil 303 , and a magnetic circuit assembly 304 .

[0110] The frame 302 can be fixedly connected to the fixing frame 3. The frame 302 can be installed around the periphery of the connecting hole 34 of the fixing frame 3 to secure the sound-generating device 30 to the fixing frame 3. The frame 302 is used to support the diaphragm 301, voice coil 303, and magnetic circuit assembly 304 of the sound-generating device 30. The frame 302 and the housing can be relatively independent components, and the frame 302 can be connected to the housing by bonding, welding, screwing, etc. For example, the sound-generating device 30 can be mounted to the housing by bonding the frame 302 to the opening of the housing.

[0111] The diaphragm 301 can be fixed to the frame 302. The diaphragm 301 can be located at the communication hole 34. The area of ​​the diaphragm 301 can be approximately the same as the area of ​​the communication hole 34. One side of the diaphragm 301 can communicate with the external space of the fixing frame 3 to enable the diaphragm 301 to vibrate and produce sound. For example, one side of the diaphragm 301 can be exposed from the fixing frame 3 and communicate with the sound outlet 201; the other side of the diaphragm 301 can communicate with the first cavity 20b.

[0112] The magnetic circuit assembly 304 can be fixed to the basin frame 302, and the magnetic circuit assembly 304 can be arranged opposite to the diaphragm 301. The magnetic circuit assembly 304 can be located on the side of the diaphragm 301 facing the back plate 1. The magnetic circuit assembly 304 can have a magnetic gap. For example, the magnetic circuit assembly 304 can include a magnet 3041, a magnetic conductive member 3042, and a washer 3043. The magnetic conductive member 3042 is fixed to the surface of one magnetic pole of the magnet 3041, and the washer 3043 is fixed to the surface of the other magnetic pole of the magnet 3041. A magnetic gap of the magnetic circuit assembly 304 can be formed between the magnet 3041 and the washer 3043.

[0113] One end of the voice coil 303 is fixed to the diaphragm 301, and the other end is located in the magnetic gap of the magnetic circuit assembly 304. The voice coil 303 can be formed by winding a wire. When power is applied to the voice coil 303, an interaction force is generated between the voice coil 303 and the magnetic circuit assembly 304, driving the voice coil 303. Since the voice coil 303 is fixedly connected to the diaphragm 301, the voice coil 303 causes the diaphragm 301 to vibrate, thereby producing sound.

[0114] In this embodiment, the sound-emitting device 30 can be assembled and installed as a whole on the fixing frame 3. The space on one side of the diaphragm 301 of the sound-emitting device 30 is connected to the outer space of the display device 100 through the sound outlet 201, so that the sound-emitting device 30 can produce sound. The space on the other side of the diaphragm 301 is connected to the first cavity 20b to improve the sound quality of the sound-emitting device 30. The sound-emitting device 30 itself does not need to form a large sound cavity, and the structure of the sound-emitting device 30 is relatively simple.

[0115] In some other embodiments, the sound-generating device 30 may include more components, which is not strictly limited in this embodiment. In some other embodiments, the sound-generating device 30 may also adopt other structures or principles to achieve sound generation, which is not strictly limited in this embodiment.

[0116] See also Figure 5 , Figure 5 yes Figure 1 The internal structure of the display device 100 in some other embodiments is shown in FIG. Figure 5 The display device 100 of the embodiment may include Figure 4 Most of the technical features of the display device 100 of the embodiment are mainly described below. The differences between the two are described below, and most of the technical features that are the same between the two are not described in detail.

[0117] Figure 5 The display device 100 of the embodiment and Figure 4 The main difference of the display device 100 of the embodiment lies in the arrangement of the housing assembly 20 .

[0118] In some embodiments, the back panel 1 includes a first portion 12, a raised portion 13, and a second portion 14. The raised portion 13 connects the first portion 12 and the second portion 14, surrounds the second portion 14, and the first portion 12 surrounds the raised portion 13. The raised portion 13 protrudes toward a side away from the display assembly 10. The raised portion 13 is connected to the fixing frame 3, and the second portion 14 is disposed opposite the sound-generating device 30.

[0119] For example, the first portion 12 may be substantially in the form of a plate and may be fixedly connected to the fixing portion 31 of the fixing frame 3 .

[0120] For example, the raised portion 13 may be a generally annular structure. Since the back plate 1 may be a thin plate, the raised portion 13 may be a bent raised structure. For example, the raised portion 13 may be formed by a process such as stamping. The raised portion 13 may have a height that is substantially the same as the height of the fixing portion 31 of the fixing frame 3, but is not limited thereto.

[0121] For example, the protrusion 13 can be fixedly connected to the fixing portion 31 of the fixing frame 3. The shape of the protrusion 13 corresponds to the shape of the fixing portion 31 of the fixing frame 3, so that the protrusion 13 and the fixing portion 31 can be docked and fixed.

[0122] For example, the shape of the second portion 14 can be substantially the same as that of the fixing frame 3. The second portion 14 can be a plate-like structure. For example, the second portion 14 can be a substantially rectangular plate-like structure. For example, the second portion 14 can be disposed opposite the main body 33 of the fixing frame 3, and the second portion 14 can form a sidewall of the first cavity 20b.

[0123] Among them, when the display device 100 includes a seal 6, the raised portion 13 and the fixed portion 31 can be sealed and connected by the seal 6. In this case, the shape of the raised portion 13 is easy to correspond to the shape of the seal 6, and easy to correspond to the shape of the fixed portion 31. The raised portion 13 is easy to position the installation of the seal 6 and the fixing frame 3, which is convenient for assembly. In addition, since the raised portion 13 has a high strength, the fixed portion 31 can also have a high strength. The seal 6 is elastic and connected between the raised portion 13 and the fixed portion 31, which is more conducive to the seal 6 to buffer the vibration between the fixed portion 31 and the raised portion 13, thereby reducing the risk of resonance noise. The high strength of the raised portion 13 can strengthen the back panel 1 and prevent the back panel 1 from deformation, so that the raised portion 13 and the fixed portion 31 can be better connected, reducing the leakage caused by the poor sealing effect of the seal 6 due to deformation, which is conducive to maintaining a high sound quality of the sound-emitting device 30 and improving reliability. In addition, since the raised portion 13 can be raised to a certain height and the raised portion 13 and the fixing portion 31 can be connected by the seal 6, when there is a large gap between the fixing frame 3 and the first portion 12, the seal 6 has a thinner thickness and can also connect the fixing frame 3 and the back plate 1, which facilitates the thinning setting of the seal 6, thereby reducing the cost of the seal 6.

[0124] In this embodiment, a protrusion 13 is provided, and the protrusion 13 is annular and protruding, so that the protrusion 13 is equivalent to a local thickening of the back plate 1, that is, the protrusion 13 has a reinforcing effect on the structure of the back plate 1, thereby improving the supporting performance of the back plate 1, and further facilitating the display device 100 to have higher strength and stronger deformation resistance.

[0125] See also Figure 6 , Figure 6 yes Figure 1 The internal structure of the display device 100 in some other embodiments is shown in FIG. Figure 6 The display device 100 of the embodiment may include Figure 4 Most of the technical features of the display device 100 of the embodiment are mainly described below. The differences between the two are described below, and most of the technical features that are the same between the two are not described in detail.

[0126] Figure 6 The display device 100 of the embodiment and Figure 4 The main difference between the display device 100 of the embodiment lies in the arrangement of the housing assembly 20 and the fixing bracket 3 .

[0127] In some embodiments, the back cover 2 may have a mounting hole 202, and the main body 33 may be mounted in the mounting hole 202. The space of the mounting hole 202 may overlap with the space of the communication hole 34. The mounting hole 202 may be a single hole structure. The mounting hole 202 overlapping with the communication hole 34 means that the mounting hole 202 and the communication hole 34 overlap in the thickness direction of the display device 100.

[0128] The sidewalls of the mounting hole 202 surround the main body 33 of the fixing bracket 3. The main body 33 is exposed relative to the rear cover 2. The structure of the main body 33 is used to fill the mounting hole 202 of the rear cover 2. The main body 33 can have the same function as the rear cover 2 of the housing assembly 20, namely, protecting the components within the cover space 20a of the housing assembly 20. Furthermore, since the sound-generating device 30 is mounted on the main body 33, the sound-generating device 30 is also exposed relative to the rear cover 2. It is understood that a gap can be left between the main body 33 and the rear cover 2 to facilitate assembly.

[0129] Exemplarily, the main body 33 has a first surface 331 facing away from the display assembly 10, and the back cover 2 has a second surface 21 facing away from the display assembly 10, and the first surface 331 is flush with the second surface 21. The flushness of the first surface 331 and the second surface 21 can mean that there is no large drop or turn between the two in the thickness direction of the display device 100. For example, the first surface 331 and the second surface 21 can be planes, and the first surface 331 and the second surface 21 can be coplanar. In this case, the main body 33 is equivalent to protruding toward the back plate 1 until it is flush with the back plate 1, thereby maximizing the use of the thickness space in the thickness direction of the display device 100, which is conducive to providing a larger first cavity 20b or making the display device 100 have a thinner size; in addition, the first surface 331 and the second surface 21 can roughly form a surface, making the back structure of the display device 100 more regular.

[0130] For example, the connection portion 32 of the fixing frame 3 may be a stepped structure, and a portion of the connection portion 32 may extend toward the mounting hole 202 so that the main body 33 can be located in the mounting hole 202. When the display device 100 includes a sealing member 6, the sealing member 6 may connect the connection portion 32 and the back cover 2.

[0131] For example, since the diaphragm 301 of the sound-generating device 30 can be fixed to the communication hole 34 , the diaphragm 301 can be substantially flush with the mounting hole 202 .

[0132] For example, the mounting hole 202 can be a single hole, and the area of ​​the mounting hole 202 can be larger than the area of ​​the main body 33 to accommodate the main body 33. For example, the area of ​​the mounting hole 202 can be greater than twice the area of ​​the diaphragm 301 of the sound-emitting device 30. In this case, a larger first cavity 20b is provided, thereby improving the sound quality of the display device 100.

[0133] It is understandable that compared to Figure 4 In the display device 100 of the embodiment, the mounting hole 202 of the embodiment can be opened at Figure 4 The position of the sound hole 201 of the embodiment is different from that of the embodiment, and the sound hole 201 does not need to be opened in this embodiment.

[0134] In this embodiment, the fixing frame 3 is used to fix the main body 33 of the sound-emitting device 30 so that it is exposed relative to the back cover 2. There is no other fixing structure of the shell component 20 between the main body 33 and the back cover 2, which reduces the space occupied by the shell component 20 in the thickness direction of the display device 100, further reduces the thickness of the display device 100, is beneficial to the thin setting of the display device 100, or is beneficial to increasing the volume of the first cavity 20b to improve the sound quality of the bass.

[0135] See also Figure 7 , Figure 7 yes Figure 1 The internal structure of the display device 100 shown in FIG. 1 is a schematic diagram of some other embodiments. Figure 7 The display device 100 of the embodiment may include Figure 4 Most of the technical features of the display device 100 of the embodiment are mainly described below. The differences between the two are described below, and most of the technical features that are the same between the two are not described in detail.

[0136] Figure 7 The display device 100 of the embodiment and Figure 4 The main difference between the display device 100 of the embodiment lies in the arrangement of the housing assembly 20 and the fixing bracket 3 .

[0137] In some embodiments, the back panel 1 includes a first portion 12, a raised portion 13, and a second portion 14. The raised portion 13 connects the first portion 12 and the second portion 14, surrounds the second portion 14, and the first portion 12 surrounds the raised portion 13. The raised portion 13 protrudes toward a side away from the display assembly 10. The raised portion 13 is connected to the fixing frame 3, and the second portion 14 is disposed opposite the sound-generating device 30.

[0138] Furthermore, the back cover 2 may have a mounting hole 202 disposed around the main body 33 of the fixing bracket 3. The mounting hole 202 may be flush with the connecting hole 34. The mounting hole 202 may be a single hole. The flushing of the mounting hole 202 with the connecting hole 34 means that the mounting hole 202 and the connecting hole 34 overlap in the thickness direction of the display device 100.

[0139] The specific configuration of the raised portion 13 can be found in Figure 5 For the detailed description of the embodiment, please refer to Figure 6 The relevant description of the embodiment will not be repeated in this embodiment.
