Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] As display devices become increasingly widely used, they are required to be not only practical but also aesthetically pleasing. Taking televisions as an example, various decorative frames (also known as picture frames) are currently installed around the television to enhance its appearance.

[0003] In related technologies, decorative frames typically include a top frame, a bottom frame, and two side frames on the left and right sides, which are connected and enclosed to be installed around the perimeter of the television. Generally, since a lower front cover is located at the bottom of the television, the bottom frame is wider vertically to cover the lower front cover.

[0004] To further improve the overall consistency and aesthetics of the decorative frame, it is usually necessary to widen the top bezel and the two side bezels. To save material, a hollow structure is typically formed inside the top bezel and the two side bezels. When the decorative frame is placed around the perimeter of the television, the inventors usually also add clearance holes on the decorative frame corresponding to the position of the radio module to avoid obstructing the radio module's microphone. However, the inventors discovered that after placing the decorative frame with the hollow structure around the perimeter of the television, when the radio module uses its microphone to pick up sound, some external sound enters the hollow structure of the decorative frame instead of directly entering the microphone, resulting in a decrease in the sound reception of the display device. Utility Model Content

[0005] This application discloses a display device that can prevent sound from entering the hollow cavity of the decorative frame, thus avoiding the dispersion and attenuation of the sound signal and improving the sound reception effect of the radio module.

[0006] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0007] A display device for displaying images, wherein a mounting cavity is provided on the edge side of the display device and the mounting cavity has an opening communicating with the outside of the display device;

[0008] A microphone module is disposed in the mounting cavity. The microphone module has a first microphone hole, which is disposed corresponding to the opening of the mounting cavity to expose the first microphone hole.

[0009] A decorative frame is detachably enclosing the edge of the display device. The interior of the decorative frame is hollow to form a hollow cavity. The decorative frame is provided with a second sound-receiving hole, which communicates with the hollow cavity. The second sound-receiving hole is also provided with respect to the mounting cavity to communicate with the first sound-receiving hole.

[0010] A sound transmission bracket, which is at least partially disposed in the hollow cavity and corresponding to the second sound receiving hole, has a sound transmission channel that connects the second sound receiving hole and the first sound receiving hole, and is configured to transmit sound between the second sound receiving hole and the first sound receiving hole.

[0011] In display devices with decorative frames, to ensure overall consistency and aesthetics, the top and side frames are usually widened to match the width of the bottom frame that covers the front shell. This requires the addition of hollow cavities within the top and side frames (making them solid would be wasteful of material and could lead to localized shrinkage during injection molding). Consequently, external sound entering the first microphone hole of the microphone module must pass through the hollow cavities of the top or side frames, causing the sound to be dispersed and affecting the microphone's reception.

[0012] Based on this, the display device of this application, by adding a sound transmission bracket and at least partially placing the sound transmission bracket in the hollow cavity of the decorative frame, utilizes the sound transmission channel formed by the sound transmission bracket to connect the first and second sound receiving holes. This allows the hollow cavity of the decorative frame to be isolated by the sound transmission channel, enabling external sound to enter through the second sound receiving hole and be directly transmitted to the first sound receiving hole on the sound receiving module via the sound transmission channel. This avoids sound entering the hollow cavity of the decorative frame, which would cause sound signal dispersion and attenuation, effectively improving the airtightness of the sound in the sound transmission channel and thus improving the sound reception effect of the sound receiving module. Simultaneously, because the hollow cavity of the decorative frame is effectively isolated by the sound transmission channel, unnecessary sound reflections within the hollow cavity are avoided, further improving the sound reception clarity and accuracy of the display device.

[0013] In some embodiments of this application, the sound transmission channel has a first opening and a second opening, the first opening being connected to the first sound receiving hole, the second opening being connected to the second sound receiving hole, and the first opening being closed relative to the second opening.

[0014] On the one hand, since the sound transmission channel is connected to the second sound receiving hole, that is, one end of the sound transmission channel is connected to the second sound receiving hole, the flared design at one end of the sound transmission channel near the second sound receiving hole increases the sound receiving range, allowing as much sound from outside the display device as possible to enter the sound transmission channel, thereby improving the sound receiving effect of the sound receiving module. On the other hand, since the sound transmission channel is connected to the first sound receiving hole, that is, one end of the sound transmission channel is connected to the first sound receiving hole, the constricted design at one end of the sound transmission channel near the first sound receiving hole concentrates the sound from the sound transmission channel and transmits it to the first sound receiving hole, thereby improving the sound receiving sensitivity and sound receiving clarity of the sound receiving module.

[0015] For example, the sound transmission channel can be constructed as a conical, stepped, or arc-shaped sound transmission channel, ensuring that the first opening of the sound transmission channel is set to be closer to the second opening.

[0016] In some embodiments of this application, the sound transmission bracket has an inner wall surface for enclosing and forming the sound transmission channel, the inner wall surface being inclined from the second opening toward the first opening, so that the sound transmission channel is narrowed at the first opening and widened at the second opening.

[0017] As can be seen, the inner wall surface slopes from the second opening towards the first opening, so that the sound transmission channel narrows at the first opening and widens at the second opening. That is, the cross-sectional shape of the sound transmission channel is conical. This conical structure allows the sound to be more effectively guided from the second receiving hole and transmitted to the first receiving hole through the gradually narrowing channel, effectively reducing sound diffusion and attenuation, and further improving the sound reception. Furthermore, the smooth transition of the inner wall surface of the conical structure avoids sound reflection and interference, ensuring clarity and accuracy of the sound.

[0018] In some embodiments of this application, the display device further includes:

[0019] A sealing element, wherein the sealing element is sealingly connected between the second opening of the sound transmission bracket and the decorative frame, the sealing element being configured to isolate the hollow cavity and the sound transmission channel; or,

[0020] The sound transmission bracket is integrally formed on the decorative frame so that the second opening and the second sound receiving hole are seamlessly connected.

[0021] The use of seals not only improves the airtightness of sound transmission channels but also helps isolate the hollow cavity and transmission channels, thereby further enhancing the clarity and accuracy of sound reception in the display device. Simultaneously, because the seals are made of elastic materials, they also provide cushioning and shock absorption, protecting the sound transmission bracket from external impacts and vibrations.

[0022] For example, the seal can be made of an elastic material, such as rubber, silicone, or other materials with elasticity and sealing properties. For example, the seal can be made of ethylene propylene diene monomer (EPDM) rubber. Such a material can create a good seal between the sound transmission bracket and the decorative frame, preventing sound leakage or unwanted reflections within the hollow cavity.

[0023] Alternatively, the sound transmission bracket can be integrally molded onto the decorative frame. On the one hand, this can further improve the airtightness of the sound in the sound transmission channel, while simplifying the assembly process and improving production efficiency. On the other hand, it can also improve the structural strength of the decorative frame. There is no need to open a second sound receiving hole on the decorative frame. Instead, the sound transmission bracket can be directly molded onto the decorative frame by combining the second opening and the second sound receiving hole, resulting in a simpler overall structure and higher overall structural strength.

[0024] It is understandable that the speaker mount and decorative frame can be made of the same material, such as plastic or metal, and then processed through injection molding or other one-piece molding processes. Because the speaker mount and decorative frame fit together seamlessly, a good seal is achieved without the need for additional seals, thus preventing sound leakage or unwanted reflections within the hollow cavity.

[0025] In some embodiments of this application, the sound transmission bracket includes:

[0026] The support portion has the sound transmission channel;

[0027] The extended portion is disposed on one side of the bracket portion and extends away from the sound transmission channel. The extended portion is used to connect with the decorative frame so that the sound transmission bracket is connected to the decorative frame.

[0028] It is understandable that the sound transmission bracket is connected to the decorative frame, meaning it can be directly connected to the second sound-receiving hole. This allows external sound from the display device to be directly transmitted to the sound-receiving module through the bracket, reducing sound attenuation and interference during propagation. Furthermore, the extended design not only enhances the connection stability between the sound transmission bracket and the decorative frame but also facilitates precise positioning and installation of the bracket on the frame.

[0029] In some embodiments of this application, the decorative frame includes:

[0030] The main frame is configured to engage with the edge side of the display device;

[0031] A partition portion is disposed in the main frame, and the partition portion divides the main frame into the hollow cavity and the engaging cavity, the engaging cavity being used to engage with the edge side of the display device;

[0032] The extensional portion includes:

[0033] A first plate portion is disposed on the outer peripheral side of the support portion and extends away from the support portion;

[0034] The second plate portion is bent and connected to the first plate portion, and the second plate portion extends from the second sound hole in the direction of the first sound hole;

[0035] The third plate portion is bent and connected to the second plate portion and extends away from the support portion;

[0036] The first plate is located in the hollow cavity to connect to the side of the main frame where the second sound hole is provided, and the third plate extends into the locking cavity to connect to the partition plate.

[0037] By incorporating the first plate, the contact area between the sound transmission bracket and the decorative frame is increased, providing sufficient space for the sealing element. This ensures that the sealing element fits tightly between the sound transmission bracket and the decorative frame, further improving the airtightness of the sound in the transmission channel. Simultaneously, the first plate, located in the hollow cavity and connected to the side of the main frame where the second sound-receiving hole is located, also enhances the connection stability between the sound transmission bracket and the decorative frame, improving the overall structural strength of the display device.

[0038] Furthermore, a second plate is bent and connected to the first plate, extending away from the support portion, and the second plate extends from the second sound-receiving hole towards the first sound-receiving hole. A third plate is bent and connected to the second plate, extending away from the support portion, so that the first plate is located on one side of the support portion, the third plate is located on the other side of the support portion, and the second plate connects to the first and third plates. That is, the third plate connects the decorative frame, further ensuring a stable connection between the sound-transmitting bracket and the decorative frame. This design not only ensures the precise positioning of the sound-transmitting bracket on the decorative frame but also prevents displacement or detachment of the sound-transmitting bracket during use through the limiting effect between the locking cavity and the display device, thus guaranteeing the stability and reliability of the display device during long-term use.

[0039] In some embodiments of this application, the display device includes:

[0040] Display panel, the display panel being used to display images;

[0041] Back panel, the display panel is disposed on the back panel;

[0042] The rear cover is disposed on the side of the back plate opposite to the display panel, and the rear cover and the back plate together form the mounting cavity;

[0043] The decorative frame is detachably fitted around the edge of the back panel and the rear shell.

[0044] It is understood that the display device can be a borderless display device or a bordered display device. When the display device is a borderless display device, the decorative frame is detachably enclosing the edge side of the back panel and the rear shell, while when the display device is a bordered display device, the bordered display device includes a frame body that encloses the edge side of the back panel and the rear shell, and the decorative frame is detachably enclosing the edge side of the frame body.

[0045] When the display device is a frameless display device, the lower edge of the display device requires the decorative frame to have a wider enclosure width. In order to ensure the overall consistency and aesthetics of the decorative frame, the upper and side frames of the decorative frame have hollow cavities. However, since the sound from outside the display device will first pass through the hollow cavity before entering the first sound hole on the sound receiving module, the sound signal is dispersed and attenuated.

[0046] Based on this, this application sets the sound transmission bracket in the decorative frame and connects the second sound receiving hole and the first sound receiving hole, so that the sound can directly enter the first sound receiving hole through the sound transmission channel without entering the hollow cavity, thereby effectively improving the sound reception clarity and accuracy of the display device.

[0047] Furthermore, by directly enclosing the edges of the back panel and rear shell with a decorative frame, the frame structure of the display device can be reduced, making the display device more concise and aesthetically pleasing, and effectively saving costs. In addition, the borderless design can effectively increase the screen-to-body ratio of the display device, thereby improving the user's viewing experience. At the same time, the detachable connection between the decorative frame and the back panel / rear shell makes it easy for users to replace or clean the decorative frame, improving the practicality of the display device and the user experience.

[0048] In some embodiments of this application,

[0049] The first microphone hole includes multiple microphone holes, which are spaced apart along a first direction;

[0050] The second sound-receiving hole extends along the first direction to form an elongated hole, and the extension range of the second sound-receiving hole in the first direction covers multiple first sound-receiving holes;

[0051] Wherein, the first direction is the width direction or the height direction of the display device.

[0052] Compared to setting multiple second microphone holes corresponding to multiple first microphone holes, setting the second microphone hole as an elongated hole covering multiple first microphone holes allows more sound to enter the sound transmission channel through the second microphone hole, thereby improving the microphone module's sound reception efficiency and range.

[0053] For example, the first microphone hole can be one, two, three, four, five, six, etc., and this application embodiment does not limit this. For example, the shape of the second microphone hole can be a long racetrack shape or a rectangle, and this application embodiment does not limit this.

[0054] In some embodiments of this application, the display device includes:

[0055] The upper edge is provided with the mounting cavity;

[0056] The lower edge and the upper edge are disposed opposite each other along the height direction of the display device;

[0057] Two side edges are arranged opposite each other along the width direction of the display device, and the upper edge, the lower edge, and the two side edges are connected and enclosed by each other;

[0058] The decorative frame includes:

[0059] The upper frame is detachably disposed on the upper edge, and the upper frame is provided with the second sound receiving hole;

[0060] A bottom border, which is detachably disposed on the bottom edge;

[0061] Two side frames, each of which is detachably disposed on one of the two side edges;

[0062] The upper frame and the side frame both have hollow cavities, and the upper frame is provided with the second sound-receiving hole.

[0063] Since the speakers of display devices are typically located at the bottom or side, placing the microphone module on the top of the display device accordingly avoids the sound emitted by the speakers being received by the microphone module, preventing echoes or sound confusion, thereby improving the accuracy of the microphone module's speech recognition. Furthermore, since display devices are usually placed on a table or mounted on a wall, and the user is typically in front of the display, placing the microphone module on the top of the display device, with the second microphone hole closer to the user's speaking direction, results in better sound pickup. It also effectively prevents the display device from being obstructed by other objects on the table, ensuring the clarity of the sound signal received by the microphone module.

[0064] In some embodiments of this application, the decorative frame includes:

[0065] The main frame is configured to engage with the edge side of the display device;

[0066] A partition portion is disposed in the main frame, and the partition portion divides the main frame into the hollow cavity and the engaging cavity, the engaging cavity being used to engage with the edge side of the display device;

[0067] A magnetic suction element is disposed in the partition portion and located in the engagement cavity, and the magnetic suction element is configured to magnetically connect to the edge side of the display device.

[0068] The decorative frame can be detachably connected to the display device using magnetic fasteners, which improves the convenience and stability of its installation. The magnetic fasteners can be magnets or other magnetic materials, and the edges of the display device can be fitted with magnetic or ferrous materials to cooperate with the magnetic fasteners for magnetic connection. Of course, as other embodiments, the decorative frame can also be detachably connected to the display device using clips, screws, or other methods; this application does not limit this approach.

[0069] Compared with the prior art, the beneficial effects of this application are:

[0070] The display device disclosed in this application includes a mounting cavity on the edge side of a display device used for displaying images. The mounting cavity has an opening communicating with the outside of the display device. A sound receiving module is disposed in the mounting cavity and has a first sound receiving hole. The first sound receiving hole is disposed corresponding to the opening of the mounting cavity to expose the first sound receiving hole. The display device also includes a decorative frame and a sound transmission bracket. The decorative frame is detachably surrounded on the edge side of the display device. The interior of the decorative frame has a hollow cavity, and a second sound receiving hole is disposed corresponding to the mounting cavity to communicate with the first sound receiving hole. The sound transmission bracket is at least partially disposed in the hollow cavity and is disposed corresponding to the second sound receiving hole. The sound transmission bracket has a sound transmission channel communicating with the second sound receiving hole and the first sound receiving hole. The sound transmission channel is configured to transmit sound between the second sound receiving hole and the first sound receiving hole.

[0071] The display device of this application, by adding a sound transmission bracket and at least partially placing the sound transmission bracket in the hollow cavity of the decorative frame, utilizes the sound transmission channel formed by the sound transmission bracket to connect the first and second sound receiving holes. This allows the hollow cavity of the decorative frame to be isolated by the sound transmission channel, enabling external sound to enter through the second sound receiving hole and be directly transmitted to the first sound receiving hole on the sound receiving module via the sound transmission channel. This avoids sound entering the hollow cavity of the decorative frame, thus preventing sound signal dispersion and attenuation, and effectively improves the airtightness of the sound in the sound transmission channel, thereby improving the sound reception effect of the sound receiving module. Simultaneously, because the hollow cavity of the decorative frame is effectively isolated by the sound transmission channel, unnecessary reflections and interference of sound within the hollow cavity are avoided, further improving the sound reception clarity and accuracy of the display device.

[0091] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0092] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0093] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0094] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0095] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0096] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0097] As the application scenarios of display devices continue to expand, they not only need to possess excellent practicality, but also have increasingly higher requirements for aesthetics. Taking televisions as an example, in order to enhance the aesthetics of televisions, the common practice is to install decorative frames (also known as picture frames) around the television.

[0098] In related technologies, the decorative frame generally consists of a top frame, a bottom frame, and two side frames on the left and right, which together enclose and connect to the outer perimeter of the television. Typically, a lower front cover is located at the bottom of the television, and to conceal the lower front cover, the bottom frame is designed to be relatively wide in the vertical direction.

[0099] When the display device is a frameless display, a wider decorative frame is needed to enclose the lower edge. To ensure the overall consistency and aesthetics of the decorative frame, the top and side frames are designed with hollow cavities. While this design offers some advantages in terms of material savings, after the decorative frame is installed around the display device, external sound first passes through the hollow cavities of the top or side frames before entering the first microphone hole on the microphone module. During this process, the sound signal is dispersed and attenuated. Consequently, when the microphone module uses the first microphone hole to pick up sound, some external sound enters the hollow cavities of the decorative frame and fails to reach the first microphone hole directly, ultimately resulting in poor sound reception of the display device.

[0100] In view of this, the display device disclosed in this application can prevent sound from entering the hollow cavity of the decorative frame, thus avoiding the dispersion and attenuation of the sound signal and effectively improving the airtightness of the sound transmission channel, thereby improving the sound reception effect of the receiver module. At the same time, since the hollow cavity of the decorative frame is effectively isolated by the sound transmission channel, unnecessary sound reflections within the hollow cavity are avoided, further improving the sound reception clarity and accuracy of the display device.

[0101] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0102] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the display device provided in the embodiments of this application. Figure 2 This is an exploded view of the display device provided in the embodiments of this application. Figure 3 This is a front view of a display device provided in an embodiment of this application. This application discloses a display device 100, which can be an organic light-emitting diode (OLED) display device, a light-emitting diode (LED) display device, a liquid crystal display (LCD) device, etc. This embodiment does not further limit the type of display device 100.

[0103] In some embodiments, the display device 100 includes a display unit 101, which includes an upper edge 1011, a lower edge 1012, and two side edges 1013. The lower edge 1012 and the upper edge 1011 are disposed opposite each other along the height direction Z of the display unit 101. The two side edges 1013 are disposed opposite each other along the width direction Y of the display unit 101, and the upper edge 1011, the lower edge 1012, and the two side edges 1013 are connected and enclosed.

[0104] That is to say, the display device 101 has an upper edge 1011 and a lower edge 1012 along the height direction Z, two side edges 1013 along the width direction Y, and a front side (not shown) and a rear side (not shown) along the thickness direction X. Among them, the side of the display device 101 facing the user is the front side, and the side of the display device 101 away from the user is the rear side. When the display device 101 is in a standing position (e.g., placed on a table by a base) or a hanging position (e.g., hung on a wall by a wall mount bracket), the absolute height of the upper edge 1011 of the display device 101 is higher than the absolute height of the lower edge 1012.

[0105] It is understandable that the extension direction between the upper edge 1011 and the lower edge 1012 is the height direction Z of the display device 101, the extension direction between the two side edges 1013 is the width direction Y of the display device 101, and the extension direction between the front and rear sides is the thickness direction X of the display device 101. It can be seen that among the width direction Y, the thickness direction X, and the height direction Z, all are perpendicular to each other. That is to say, the width direction Y is perpendicular to the thickness direction X, the width direction Y is perpendicular to the height direction Z, and the thickness direction X is perpendicular to the height direction Z.

[0106] In some embodiments, the display device 101 includes a display panel 10 for displaying images.

[0107] In some embodiments, the display device 101 includes a back plate 20, and a display panel 10 is disposed on the front side of the back plate 20. A light source (not shown) and an optical film assembly (not shown) are also disposed on the front side of the back plate 20, and the light source, the optical film assembly, and the display panel 10 are arranged sequentially from the rear side to the front side of the display device 101. Light emitted from the light source is projected onto the display panel 10 after passing through the optical film assembly, and image information is displayed on the display panel 10 after being processed by the display panel 10.

[0108] In some embodiments, the display device 101 includes a rear cover 30, which is disposed on the side of the back plate 20 away from the display panel 10, that is, the rear cover 30 is disposed on the rear side of the back plate 20.

[0109] In some embodiments, the rear cover 30 and the back plate 20 together form a mounting cavity 10b, which has an opening communicating with the outside of the display device 101. The mounting cavity 10b is used to mount the motherboard, power board, etc.

[0110] Specifically, the mounting cavity 10b is disposed on the upper edge 1011 of the display device 101 and has an opening communicating with the outside of the display device 101. Of course, as other embodiments, the mounting cavity 10b may also be disposed on the lower edge 1012 of the display device 101, or the mounting cavity 10b may also be disposed on the side edge 1013 of the display device 101. This application embodiment does not limit this.

[0111] Please see Figure 4 , Figure 4 for Figure 3 A cross-sectional view of AA. In some embodiments, the display device 101 includes a sound receiving module 40, which is disposed in the mounting cavity 10b. The sound receiving module 40 has a first sound receiving hole 401, which is provided to expose the opening of the mounting cavity 10b. The sound receiving module 40 collects external sound through the first sound receiving hole 401.

[0112] In some embodiments, the display device 100 includes a decorative frame 50, which is detachably surrounded on the edge side 10a of the back panel 20 and the rear shell 30, and the interior of the decorative frame 50 is hollow to form a hollow cavity 50a.

[0113] It is understood that the display device 101 can be a borderless display device or a framed display device. When the display device 101 is a borderless display device, the decorative frame 50 is detachably surrounded on the edge side 10a of the back panel 20 and the rear shell 30. When the display device 101 is a framed display device 101, the framed display device 101 includes a frame body that surrounds the edge side 10a of the back panel 20 and the rear shell 30, and the decorative frame 50 is detachably surrounded on the edge side 10a of the frame body. This application embodiment does not limit this. This application will subsequently describe the display device 101 as a borderless display device 101 as an example.

[0114] When the display device 101 is a frameless display device, the lower edge 1012 of the display device 101 requires the decorative frame 50 to have a wider enclosure width. In order to ensure the overall consistency and aesthetics of the display device 100, there will be a hollow cavity 50a inside the decorative frame 50. However, since the sound outside the display device 101 will first pass through the hollow cavity 50a before entering the first sound receiving hole 401 on the sound receiving module 40, the sound signal is dispersed and attenuated.

[0115] Based on this, this application sets the sound transmission bracket 60 in the decorative frame 50 and connects the second sound receiving hole 511 and the first sound receiving hole 401, so that the sound can directly enter the first sound receiving hole 401 through the sound transmission channel 60a, instead of entering the hollow cavity 50a, thereby effectively improving the sound reception clarity and accuracy of the display device 100.

[0116] Furthermore, by directly enclosing the back panel 20 and the edge 10a of the rear shell 30 with the decorative frame 50, the frame structure of the display device 101 can be reduced, making the display device 100 more concise and aesthetically pleasing, and effectively saving costs. In addition, the borderless design can effectively increase the screen-to-body ratio of the display device 100, thereby improving the user's viewing experience. At the same time, the detachable connection design between the decorative frame 50 and the back panel 20 and rear shell 30 makes it easy for users to replace or clean the decorative frame 50, improving the practicality of the display device 100 and the user experience.

[0117] See you again Figures 2 to 3 In some embodiments, the decorative frame 50 includes an upper frame 501, a lower frame 502, and two side frames 503. The upper frame 501 is detachably disposed on the upper edge 1011 of the display device 101, the lower frame 502 is detachably disposed on the lower edge 1012 of the display device 101, and the two side frames 503 are detachably disposed on the two side edges 1013 of the display device 101, respectively.

[0118] The upper frame 501 and the side frame 503 both have hollow cavities 50a. For example, the lower frame 502 may or may not have a hollow structure. The specific structure of the lower frame 502 can be set as needed. That is to say, the radio module 40 can be set at the lower edge 1012 of the display device 101, that is, the second radio hole 511 can also be set on the lower frame 502. This application embodiment does not limit this.

[0119] In some embodiments, the upper border 501, lower border 502, and side border 503 of the decorative frame 50 can be configured as an integral structure, that is, the main frame 51 is an integral structure. Of course, as other embodiments, the upper border 501, lower border 502, and side border 503 of the decorative frame 50 can also be configured as separate structures, that is, the upper border 501, lower border 502, and side border 503 are each independently configured, and this application embodiment does not limit this.

[0120] In some embodiments, when a second microphone hole 511 is provided on the upper frame 501, the mounting cavity 10b is disposed on the upper edge 1011 of the display device 101, the second microphone hole 511 communicates with the hollow cavity 50a, and the second microphone hole 511 is disposed corresponding to the mounting cavity 10b to communicate with the first microphone hole 401. It can be understood that the microphone module 40 is mounted on the upper edge 1011 of the display device 101 through the mounting cavity 10b, and correspondingly, the sound transmission bracket 60 is mounted on the upper frame 501, that is, the microphone module 40 is disposed on the upper side of the display device 100 (that is, located at the upper edge 1011 of the display device 101).

[0121] Since the speakers of the display device 100 are usually located at the bottom or side of the display device 100, placing the microphone module 40 correspondingly on the upper side of the display device 100 can prevent the sound emitted by the speakers from being received by the microphone module 40, thus avoiding echoes or sound confusion and improving the voice recognition accuracy of the microphone module 40. Furthermore, since the display device 100 is usually placed on a table or mounted on a wall, and the user is usually located in front of the display device 101, placing the microphone module 40 correspondingly on the upper side of the display device 100, with the second microphone hole 511 closer to the user's voice direction, results in better sound reception by the microphone module 40. At the same time, it can also effectively prevent the display device 101 from being blocked by other objects on the table, thus ensuring the clarity of the sound signal received by the microphone module 40.

[0122] Of course, as another embodiment, in order to make the first sound hole 401 and the second sound hole 511 correspondingly connected, when the second sound hole 511 is provided on the side frame 503, the mounting cavity 10b can be provided on the side edge 1013 of the display device 101. This application embodiment does not limit this.

[0123] The following description will take the example of mounting cavity 10b being located on the upper edge 1011 of display device 101, and a second sound hole 511 being provided on the upper frame 501.

[0124] Please see Figure 5 , Figure 5 This is a top view of a display device provided in an embodiment of this application. In some embodiments, the first microphone hole 401 may include multiple holes, and the multiple first microphone holes 401 are spaced apart along a first direction. For example, the number of first microphone holes 401 may be one, two, three, four, five, six, etc., and this embodiment of the application does not limit this.

[0125] Optionally, the second sound-receiving hole 511 extends along the first direction to form an elongated hole, and the extension range of the second sound-receiving hole 511 in the first direction covers multiple first sound-receiving holes 401. Compared to setting multiple second sound-receiving holes 511 corresponding to multiple first sound-receiving holes 401, setting the second sound-receiving hole 511 as an elongated hole covering multiple first sound-receiving holes 401 allows more sound to enter the sound transmission channel 60a through the second sound-receiving hole 511, thereby improving the sound reception efficiency and sound reception range of the sound-receiving module 40. For example, the shape of the second sound-receiving hole 511 can be an elongated racetrack shape or a rectangle, and this embodiment of the application does not limit this.

[0126] Optionally, the first direction is the width direction Y or the height direction Z of the display device 101. When the first direction is the width direction Y of the display device 101, the second microphone hole 511 is disposed on the upper frame 501; when the first direction is the height direction Z of the display device 101, the second microphone hole 511 is disposed on the side frame 503. This application embodiment does not limit this.

[0127] Please refer to the following: Figures 6 to 8 , Figure 6 This is a schematic diagram of the upper frame and the sound transmission bracket provided in the embodiments of this application. Figure 7 This is a cross-sectional view of the upper frame and the sound transmission bracket provided in the embodiments of this application. Figure 8 for Figure 6 A partial enlarged view at point B. In some embodiments, the upper frame 501 includes a main frame 51 and a partition portion 52. The main frame 51 is configured to engage with the edge side 10a of the display device 101. The partition portion 52 is disposed in the main frame 51 and divides the main frame 51 into a hollow cavity 50a and an engaging cavity 50b. The engaging cavity 50b is used to engage with the edge side 10a of the display device 101.

[0128] It is understood that the main frame 51 can be a hollow, elongated rectangular structure to enclose the edge side 10a of the display device 101; the partition 52 can be a plate-shaped, block-shaped, or sheet-shaped elongated structure to correspond to the edge side 10a of the display device 101.

[0129] Please see Figure 9 , Figure 9 for Figure 6 A partial enlarged view at point C. Optionally, the upper frame 501 also includes a magnetic member 53, which is disposed on the side of the partition portion 52 facing the engaging cavity 50b, so that the upper frame 501 is magnetically connected to the edge side 10a of the display device 101. The magnetic member 53 enables a detachable connection of the decorative frame 50 to the display device 101, improving the convenience and stability of the installation of the decorative frame 50. The magnetic member 53 can be a magnet or other magnetic material, and the edge side 10a of the display device 101 can be provided with a magnetic material or ferrous material that cooperates with the magnetic member 53 to achieve a magnetic connection. Of course, as other embodiments, the decorative frame 50 can also be detachably connected to the display device 101 by means of clips, screws, etc., and this application embodiment does not limit this.

[0130] It is understandable that the specific structure of the bottom border 502 and the side border 503 can be referred to the description of the specific structure of the top border 501, and will not be repeated here.

[0131] Please refer to the following: Figures 10 to 12 , Figure 10This is a schematic diagram of the structure of the sound transmission bracket provided in the embodiments of this application. Figure 11 This is a top view of the sound transmission bracket provided in an embodiment of this application. Figure 12 for Figure 11 A cross-sectional view of DD. In some embodiments, the display device 100 includes a sound transmission bracket 60, which is at least partially disposed in a hollow cavity 50a and corresponds to a second sound receiving hole 511. The sound transmission bracket 60 has a sound transmission channel 60a that connects the second sound receiving hole 511 and a first sound receiving hole 401. The sound transmission channel 60a is configured to transmit sound between the second sound receiving hole 511 and the first sound receiving hole 401.

[0132] In a display device 100 with a decorative frame 50, in order to ensure the overall consistency and aesthetics of the decorative frame 50, the upper frame 501 and side frame 503 of the decorative frame 50 are usually widened so that their width is flush with the width of the lower frame 502 of the lower front shell of the display device 101. This results in the need to add an extra hollow cavity 50a inside the upper frame 501 and side frame 503 (if it is made solid, it will not only waste material but may also cause local shrinkage during injection molding). As a result, the sound from outside the display device 101 needs to pass through the hollow cavity 50a of the upper frame 501 or side frame 503 before entering the first sound hole 401 of the sound receiving module 40. This causes the sound to be dispersed by the hollow cavity 50a, thus affecting the sound receiving effect of the display device 100.

[0133] Based on this, the display device 100 of this application adds a sound transmission bracket 60 and at least partially sets the sound transmission bracket 60 in the hollow cavity 50a of the decorative frame 50. Thus, the sound transmission channel 60a formed by the sound transmission bracket 60 connects the first sound receiving hole 401 and the second sound receiving hole 511, so that the hollow cavity 50a of the decorative frame 50 can be isolated by the sound transmission channel 60a. This allows external sound to enter from the second sound receiving hole 511 and be directly transmitted to the first sound receiving hole 401 on the sound receiving module 40 via the sound transmission channel 60a. This avoids sound entering the hollow cavity 50a of the decorative frame 50 and causing sound signal dispersion and attenuation, effectively improving the airtightness of the sound in the sound transmission channel 60a, thereby improving the sound receiving effect of the sound receiving module 40. Meanwhile, since the hollow cavity 50a of the decorative frame 50 is effectively isolated by the sound transmission channel 60a, unnecessary reflections and interference of sound within the hollow cavity 50a are avoided, further improving the sound reception clarity and accuracy of the display device 100.

[0134] In some embodiments, the display device 100 further includes a seal 70, which is sealed between the second opening 602 of the sound transmission bracket 60 and the decorative frame 50. The seal 70 is configured to isolate the hollow cavity 50a and the sound transmission channel 60a. The seal 70 not only improves the airtightness of sound in the sound transmission channel 60a but also helps to isolate the hollow cavity 50a and the sound transmission channel 60a, thereby further improving the sound reception clarity and accuracy of the display device 100. Simultaneously, since the seal 70 is made of an elastic material, it also has a certain buffering and shock absorption function, protecting the sound transmission bracket 60 from external impacts and vibrations.

[0135] For example, the seal 70 can be made of an elastic material, such as rubber, silicone, or other materials with elasticity and sealing properties. For example, the seal 70 can be made of ethylene propylene diene monomer (EPDM) rubber. Such a material can form a good seal between the sound transmission bracket 60 and the decorative frame 50, preventing sound leakage or unwanted reflections within the hollow cavity 50a.

[0136] For example, the seal 70 can also be fixedly connected to the sound transmission bracket 60 and the decorative frame 50 by adhesive or other fixing methods to ensure its stability and reliability during long-term use. For example, the adhesive may include AB glue, instant adhesive, hot melt adhesive, or other adhesives with strong adhesion. On the one hand, these adhesives can form a strong bond between the seal 70, the sound transmission bracket 60, and the decorative frame 50, preventing the seal 70 from falling off or shifting, maintaining the durability and reliability of the sealing effect, thereby ensuring the airtightness of the sound in the sound transmission channel 60a, and thus effectively improving the sound reception effect of the sound receiving module 40. On the other hand, since the second sound receiving hole 511 needs to be set on the upper frame 501, its structure is damaged, resulting in poor structural strength of the upper frame 501. Through the stable bonding of adhesives such as AB glue, the structural strength of the upper frame 501 can be effectively enhanced, making the entire display device 100 more durable and reliable.

[0137] Specifically, the seal 70 may have a shape and size that matches the second opening 602 of the sound transmission bracket 60 to ensure that the seal 70 can fit tightly against the second opening 602. It is understood that the seal 70 may be configured as an annular structure, which can surround the second opening 602 of the sound transmission bracket 60 to form a complete seal. Of course, as in other embodiments, the seal 70 may also be configured as other shapes, such as rectangular, elliptical, etc., and this application embodiment does not limit this.

[0138] In other embodiments, the sound transmission bracket 60 is integrally formed onto the decorative frame 50, so that the second opening 602 and the second sound receiving hole 511 are seamlessly connected. By integrally forming the sound transmission bracket 60 onto the decorative frame 50, on the one hand, the airtightness of the sound in the sound transmission channel 60a can be further improved, while simplifying the assembly process and improving production efficiency; on the other hand, the structural strength of the decorative frame 50 can also be improved, as there is no need to open the second sound receiving hole 511 separately on the decorative frame 50. Instead, the sound transmission bracket 60 is directly formed onto the decorative frame 50 by combining the second opening 602 and the second sound receiving hole 511, resulting in a simpler overall structure and higher overall structural strength.

[0139] It is understood that the sound transmission bracket 60 and the decorative frame 50 can be made of the same material, such as plastic or metal, and then processed by injection molding or other one-piece molding processes. Because the sound transmission bracket 60 and the decorative frame 50 are seamlessly joined, a good sealing effect can be achieved without the need for an additional seal 70, thereby preventing sound leakage or unwanted reflections within the hollow cavity 50a.

[0140] Of course, as other embodiments, the sound transmission bracket 60 and the decorative frame 50 can also be fixedly connected in other ways, such as by screws, clips, etc., and this application embodiment does not limit this. Optionally, the sound transmission bracket 60 and the decorative frame 50 can be made the same color. For example, when the color of the decorative frame 50 is yellow, the color of the sound transmission bracket 60 can also be set to yellow, so that the sound transmission bracket 60 and the decorative frame 50 have the same color, so that the sound transmission bracket 60 and the decorative frame 50 are more visually unified and coordinated, and improve the overall aesthetics of the display device 100.

[0141] To facilitate understanding of the structure of the sound transmission bracket 60, the specific structure of the sound transmission bracket 60 will be described in detail below with reference to the embodiments and accompanying drawings.

[0142] In some embodiments, the sound transmission channel 60a has a first opening 601 and a second opening 602. The first opening 601 is connected to the first sound receiving hole 401, and the second opening 602 is connected to the second sound receiving hole 511. The first opening 601 is closed relative to the second opening 602.

[0143] It is understandable that the sound transmission channel 60a is located at one end of the first sound receiving hole 401 with a narrow opening, and at one end of the second sound receiving hole 511 with a wide opening. On the one hand, since the sound transmission channel 60a is connected to the second sound receiving hole 511, that is, the sound transmission channel 60a is located at one end of the second sound receiving hole 511 and is connected to the second sound receiving hole 511, the sound transmission channel 60a is widened at one end of the second sound receiving hole 511, which can increase the sound receiving range and allow as much sound from outside the display device 101 as possible to enter the sound transmission channel 60a, thereby improving the sound receiving effect of the sound receiving module 40. On the other hand, since the sound transmission channel 60a is connected to the first sound receiving hole 401, that is, the sound transmission channel 60a is located at one end of the first sound receiving hole 401 and is connected to the first sound receiving hole 401, the sound transmission channel 60a is narrowed at one end of the first sound receiving hole 401, which can concentrate the sound of the sound transmission channel 60a and transmit it to the first sound receiving hole 401, thereby improving the sound receiving sensitivity and sound receiving clarity of the sound receiving module 40.

[0144] For example, the cross-sectional shape of the sound transmission channel 60a can be constructed as a conical, stepped, or arc-shaped sound transmission channel 60a, ensuring that the first opening 601 of the sound transmission channel 60a is closed relative to the second opening 602. This application embodiment does not limit this.

[0145] Optionally, the sound transmission bracket 60 has an inner wall surface 603 for enclosing and forming a sound transmission channel 60a. The inner wall surface 603 is inclined from the second opening 602 towards the first opening 601, so that the sound transmission channel 60a is narrowed at the first opening 601 and widened at the second opening 602. It can be seen that the inner wall surface 603 is inclined from the second opening 602 towards the first opening 601, so that the sound transmission channel 60a is narrowed at the first opening 601 and widened at the second opening 602. That is, the cross-sectional shape of the sound transmission channel 60a is conical. The conical structure of the sound transmission channel 60a can more effectively guide sound into the second receiving hole 511 and transmit sound to the first receiving hole 401 through the gradually narrowing sound transmission channel 60a, effectively reducing sound diffusion and attenuation, and further improving the sound reception effect. In addition, the smooth transition of the conical inner wall surface 603 avoids sound reflection and interference, ensuring the clarity and accuracy of the sound.

[0146] It is understandable that the above-mentioned "retracting" refers to the reduction in the opening width of the sound transmission channel 60a, while the above-mentioned "expanding" refers to the increase in the opening width of the sound transmission channel 60a.

[0147] See again Figures 11 to 12In some embodiments, the sound transmission bracket 60 includes a bracket portion 61 and an extension portion 62. The bracket portion 61 has a sound transmission channel 60a, and the extension portion 62 is disposed on one side of the bracket portion 61 and extends away from the sound transmission channel 60a. The extension portion 62 is used to connect with the decorative frame 50, so that the sound transmission bracket 60 is connected to the decorative frame 50. It can be understood that the sound transmission bracket 60 is connected to the decorative frame 50, that is, the sound transmission bracket 60 can be directly connected to the second sound receiving hole 511, so that the sound from outside the display device 101 can be directly transmitted to the sound receiving module 40 through the sound transmission bracket 60, reducing the attenuation and interference of the sound during the propagation process. In addition, the design of the extension portion 62 not only enhances the connection stability between the sound transmission bracket 60 and the decorative frame 50, but also facilitates the precise positioning and installation of the sound transmission bracket 60 on the decorative frame 50.

[0148] For example, the extension portion 62 may be provided with a snap-fit ​​structure, threaded holes, or other connection structures to achieve a secure and detachable connection with the decorative frame 50. This design not only facilitates the replacement and maintenance of the sound transmission bracket 60 but also ensures the sound reception performance of the display device 100 during long-term use. Simultaneously, the extension portion 62 also provides cushioning and support, protecting the sound transmission bracket 60 from external impacts and vibrations, thereby improving the durability and reliability of the display device 100.

[0149] Optionally, the outer extension portion 62 includes a first plate portion 621, a second plate portion 622, and a third plate portion 623. The first plate portion 621 is disposed on the outer periphery of the support portion 61 and extends away from the support portion 61. The second plate portion 622 is bent and connected to the first plate portion 621, and the second plate portion 622 extends from the second sound receiving hole 511 towards the first sound receiving hole 401. The third plate portion 623 is bent and connected to the second plate portion 622 and extends away from the support portion 61. The first plate portion 621 is located in the hollow cavity 50a to connect to the side of the main frame 51 where the second sound receiving hole 511 is located, and the third plate portion 623 extends into the engagement cavity 50b to connect to the partition portion 52.

[0150] By setting the first plate portion 621, the contact area between the sound transmission bracket 60 and the decorative frame 50 can be increased, providing sufficient space for the installation of the sealing element 70. This ensures that the sealing element 70 can fit tightly between the sound transmission bracket 60 and the decorative frame 50, further improving the airtightness of the sound in the sound transmission channel 60a. At the same time, the first plate portion 621 is located in the hollow cavity 50a and connected to the side of the main frame 51 where the second sound receiving hole 511 is provided. This also enhances the connection stability between the sound transmission bracket 60 and the decorative frame 50, improving the structural strength of the entire display device 100.

[0151] Furthermore, a second plate portion 622 is bent and connected to the first plate portion 621 and extends away from the bracket portion 61, with the second plate portion 622 extending from the second sound receiving hole 511 towards the first sound receiving hole 401. A third plate portion 623 is bent and connected to the second plate portion 622 and extends away from the bracket portion 61, such that the first plate portion 621 is located on one side of the bracket portion 61, and the third plate portion 623 is located on the other side of the bracket portion 61, with the second plate portion 622 connected to the first plate portion 621 and the third plate portion 623. That is, the connection of the decorative frame 50 is achieved through the third plate portion 623, thereby further realizing a stable connection between the sound transmission bracket 60 and the decorative frame 50. This design not only ensures the precise positioning of the sound transmission bracket 60 on the decorative frame 50, but also prevents the sound transmission bracket 60 from shifting or falling off during use through the limiting effect between the locking cavity 50b and the display device 101, thereby ensuring the stability and reliability of the display device 100 during long-term use.

[0152] The display device disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the display device and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
