[0038] Existing all-in-one LED displays are typically designed with a structural lower frame, which houses a controller module. The audio speaker unit is often integrated into the control module. This means that traditional audio speaker units are only suitable for products with a structural lower frame, and are unusable for products without a lower frame that require greater simplicity. Furthermore, due to the high frequency of operation of the audio speaker unit and its vulnerability to wear and tear, daily use requires disassembly, maintenance, and replacement. This requires first removing the structural lower frame to expose the controller module, and then removing the controller module to access the audio speaker unit. This cumbersome and inconvenient maintenance operation impacts both efficiency and user experience.

[0039] In response to the above-mentioned problems, the present application adapts the structure of the shell 30 and the light board 20 to reserve space for installing the speaker module 10, so that the speaker module 10 can be assembled between the shell 30 and the light board 20, and the speaker module 10 is installed inside the display module, thereby eliminating the lower frame of the structure, making the speaker module 10 suitable for the installation needs of frameless products; furthermore, since the light board 20 can be removed from the shell 30, it is convenient to maintain the light board 20, making the maintenance of the speaker module 10 convenient and efficient.

[0040] For details about this application, please refer to Figure 1 and Figure 2 , provides a partial structural schematic diagram of a display module, including a speaker module 10, a light board 20 and a shell 30.

[0041] The housing 30 is a load-bearing body for loading the integrated speaker module 10 and the light board 20 .

[0042] Optionally, the material of the housing 30 may be, but is not limited to, plastic, metal, etc., and may be flexibly selected according to actual needs.

[0043] The housing 30 is provided with a receiving portion, and the speaker module 10 is detachably mounted in the receiving portion. The receiving portion can be in the form of a groove, a cavity, a window, or the like.

[0044] The light board 20 is detachably mounted on the housing 30 . When the light board 20 and the housing 30 are assembled, at least a portion of the speaker module 10 is located between the housing 30 and the light board 20 .

[0045] When the light board 20 , the speaker module 10 and the housing 30 are in an assembled structural state, the speaker module 10 is completely covered by the light board 20 below, and thus the speaker module 10 is not visible when observed from the outside.

[0046] In the present application, the light board 20 specifically includes but is not limited to a PCB board and a light-emitting body, and the light-emitting body is soldered to the PCB board. The light-emitting body can be in the form of at least one of LED lamp beads, LED light strips, LED light tubes, etc.

[0047] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the display module of this solution is applied to a display device, and a receiving portion is provided on the shell 30, so that the speaker module 10 can be installed in the receiving portion, and then the light board 20 is installed on the shell 30, so that after the three are assembled, at least part of the speaker module 10 is located between the shell 30 and the light board 20, that is, the speaker module 10 is installed inside the display module; compared with the prior art, on the one hand, this solution directly integrates the speaker module 10 into the interior of the display module, which can eliminate the structural lower frame originally arranged on the ground side of the shell 30, so that the overall appearance of the display device can be more concise, that is, the speaker module 10 can be applied to products without a lower frame; on the other hand, when the speaker module 10 needs to be maintained or replaced, it is only necessary to remove the light board 20 to directly perform relevant operations on the speaker module 10, or to take out the speaker module 10 to perform relevant operations, without the need to disassemble complicated parts, making maintenance operations convenient and labor-saving, thereby significantly improving the maintenance efficiency and experience.

[0048] It is understandable that when the speaker module 10 is moved to the inside of the display module and the lower frame is omitted, other functional components such as the controller module originally installed in the lower frame can also be installed in a suitable place in the empty cavity inside the display module.

[0049] In an optional embodiment, in order to achieve normal assembly and fixation of the light board 20 and the shell 30 during production, and to disassemble the light board 20 to expose the speaker module 10 when the speaker module 10 needs maintenance, a connecting piece is provided on the side of the shell 30 facing the light board 20, and the light board 20 is detachably connected to the shell 30 through the connecting piece.

[0050] Specifically, the housing 30 includes a panel 31 and a fixed back plate 121 . The panel 31 is arranged between the light board 20 and the fixed back plate 121 , and the connector is installed on the side of the panel 31 facing the light board 20 .

[0051] The connecting piece may be a part of the structure of the shell 30, that is, the connecting piece is formed integrally with the shell 30; or, the connecting piece may be a separate component fixed to the shell 30 in a detachable or non-detachable installation manner.

[0052] For example, in one optional embodiment, the connector is configured as a magnetic body 311, and the light panel 20 is magnetically connected to the magnetic body 311, thereby enabling a detachable assembly of the light panel 20 and the housing 30. The magnetic body 311 generates a magnetic attraction on the light panel 20, allowing the light panel 20 to be magnetically fixed to the housing 30. To disassemble the light panel 20, the light panel 20 is pulled outward. When the pulling force exceeds the magnetic attraction, the light panel 20 separates from the magnetic body 311, completing the disassembly of the light panel 20. This magnetic installation method has a simple structure and operating principle, is easy to repeatedly disassemble and assemble, and does not damage the light panel 20, making it highly feasible.

[0053] Specifically, the magnetic body 311 can be a magnet, and the magnet can be fixed to the housing 30 by bonding, inserting into a mounting groove, etc. Accordingly, the lamp board 20 is embedded with a metal insert, which is used to be fixed with the magnet by magnetic attraction.

[0054] Preferably, multiple magnetic bodies 311 and metal inserts are dispersedly arranged and set in one-to-one correspondence to form a multi-point magnetic fixing effect, thereby improving the installation stability of the lamp panel 20.

[0055] Furthermore, a positioning member is provided on one of the side of the housing 30 facing the light board 20 and the surface of the light board 20 facing the housing 30. A positioning hole is provided on the other side of the housing 30 facing the light board 20, into which the positioning member is inserted. When the light board 20 and the housing 30 are assembled, the positioning member is aligned and inserted into the positioning hole, thereby initially positioning the light board 20 for installation, preventing the light board 20 from shifting or tilting, which could affect subsequent installation operations.

[0056] Preferably, a plurality of positioning bodies and positioning holes are dispersedly arranged and provided in a one-to-one correspondence to form a multi-point positioning effect, thereby improving the positioning reliability of the light board 20 .

[0057] The positioning body can be in the form of a column, block, plate, cylinder or other structure, and can be selected according to actual needs.

[0058] See also Figure 3 Furthermore, based on any of the above embodiments, the speaker module 10 includes a speaker body 11 and a maintenance bracket 12, which are detachably assembled and matched. During production, the speaker body 11 is mounted to the housing 30 via the maintenance bracket 12. When maintenance is required on a damaged speaker body 11, the light board 20 is first removed from the housing 30, and then the maintenance bracket 12 is removed. This exposes the speaker body 11 to the operator, facilitating maintenance operations.

[0059] In this application, the display device is composed of multiple display modules spliced ​​together to obtain a larger display area and improve the display effect. For example, the display device can be a LED all-in-one machine. The LED all-in-one machine is an intelligent display device that integrates multiple functions and is mainly used in conferences, training and other occasions. It combines multiple functions such as projector, screen, multi-touch screen, video playback, audio, computer and file management in one, and has full conference functions such as interactive intelligent large screen, interactive control, remote conferencing, multi-screen mutual display, high-definition display, multimedia playback, etc.

[0060] All-in-one LED displays resemble televisions and typically reach sizes around 100 inches. Available sizes include 65-inch, 75-inch, 86-inch, 100-inch, and 110-inch. They are highly integrated, require only a 220V power supply, and are lightweight. They can be installed in a variety of ways, including wall-mounting, ceiling-mounting, and mobile bracket mounting.

[0061] The all-in-one LED display is incredibly powerful, supporting wireless projection, allowing users to wirelessly project content from their computer or phone onto the screen. It also features a capacitive touchscreen, allowing users to swipe, write, and open apps much like they would on a smartphone. Furthermore, the all-in-one LED display boasts dual operating systems, allowing it to function as both a computer and a monitor, supporting file storage, web browsing, and whiteboard functionality.

[0062] Therefore, this application, based on full consideration of maintenance convenience, combines the two different installation scenarios of the LED all-in-one machine using bracket installation and wall-mounted installation, and redesigns the maintenance bracket 12 to achieve front and rear maintenance of the speaker body 11.

[0063] See also Figures 3 to 7 Specifically, in an optional embodiment, the maintenance bracket 12 includes a rear cover 122 and a first connecting member 123, the fixed back plate 121 is provided with a removal window 121a, the rear cover 122 is detachably mounted on the first side surface of the fixed back plate 121 through the first connecting member 123, and the speaker body 11 is movably inserted into the removal window 121a.

[0064] When the LED all-in-one machine is installed using a bracket and the speaker body 11 needs to be maintained, the light board 20 is first removed to expose the first connecting member 123, and then the first connecting member 123 is removed to release the rear cover 122. At this time, the rear cover 122 can be directly removed from the rear side of the LED all-in-one machine through the removal window 121a on the fixed back plate 121, thereby exposing the speaker body 11, and then the speaker body 11 can be maintained.

[0065] It is easy to understand that the above-mentioned rear maintenance operation refers to the maintenance operation performed on the rear part of the speaker body 11 from the rear side of the LED all-in-one machine.

[0066] Please continue reading Figure 6 In the above embodiment, the rear cover 122 is provided with a recessed cavity 122a. The recessed cavity 122a is specifically rectangular and conforms to the rectangular shape of the speaker body 11. A portion of the speaker body 11 extends into the recessed cavity 122a. A sound outlet 1221a is defined in the sidewall of the recessed cavity 122a. The sound outlet 1221a is positioned opposite the sound outlet portion 111 of the speaker body 11. The recessed cavity 122a accommodates a portion of the speaker body 11, thereby allowing the sound outlet 1221a to face the sound outlet portion 111. This allows sound emitted from the sound outlet portion 111 to pass through the sound outlet 1221a and into the external environment.

[0067] Please continue reading Figure 6 During frequent assembly and disassembly, the rear cover 122 is often subjected to external forces, which can easily cause it to bend, deform, or even break. To address this, a rib structure 1222a is provided on the bottom wall of the cavity 122a to strengthen and secure the back plate 121. The rib structure 1222a can effectively improve the overall structural strength of the rear cover 122, thereby avoiding or alleviating the aforementioned problem.

[0068] Please continue reading Figure 3 Furthermore, in another embodiment, the maintenance bracket 12 also includes a front cover 124 and a second connecting member 125, and the front cover 124 is detachably mounted on the second side of the fixed back plate 121 through the second connecting member 125; wherein the first side and the second side are two oppositely arranged side surfaces of the fixed back plate 121.

[0069] When the LED all-in-one is wall-mounted, the rear side of the main unit is blocked by the wall, making it impossible to perform rear maintenance on the speaker body 11. In this case, after removing the light panel 20, the second connector 125 is removed to release the front cover 124. After the front cover 124 is removed, the front of the speaker body 11 is exposed to the staff, and the speaker body 11 can then be maintained from the front.

[0070] Specifically, in the present application, the front cover plate 124 is rectangular, and its two opposite ends in the length direction are respectively connected to the fixed back plate 121 through at least one second connecting member 125.

[0071] It should be noted that since there are different functional components on the front and rear sides of the speaker body 11, the front maintenance or rear maintenance method can be flexibly selected according to the installation method of the LED all-in-one machine, which can solve different problems of the speaker body 11 in a targeted manner.

[0072] Please continue reading Figure 3In addition, in order to enable the speaker body 11 to be assembled and fixed with the maintenance bracket 12 to ensure that the speaker body 11 is positioned reliably and safely after installation, the maintenance bracket 12 also includes a third connecting member 126, and the front cover 124 is detachably connected to the speaker body 11 through the third connecting member 126.

[0073] Optionally, the above-mentioned first connecting member 123, second connecting member 125 and third connecting member 126 are all threaded components, that is, the rear cover plate 122 and the fixed back plate 121, the front cover plate 124 and the fixed back plate 121, and the front cover plate 124 and the speaker body 11 can be disassembled and assembled by threaded connection, the installation and disassembly method is simple, the connection reliability is high, and it is convenient to perform maintenance or replacement operations on the speaker body 11.

[0074] Of course, in other optional embodiments, the above-mentioned threaded connection method can also be replaced by bonding, magnetic connection, snap connection, etc., which are also within the scope of protection of this application and will not be repeated here.

[0075] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
