[0052] 1 and 2 , the present invention provides a sound emitting device 10, including:

[0053] The speaker 100 includes a first connecting portion 110; and

[0054] The shell assembly 200 has a sound cavity S; the shell assembly 200 includes a second connecting portion 230 located in the sound cavity S; the speaker 100 is disposed in the sound cavity S, and the first connecting portion 110 is connected to the second connecting portion 230.

[0055] In the technical solution of the embodiment of the present application, the shell assembly 200 has a sound cavity S, which is connected together by the first connecting part 110 of the speaker 100 and the second connecting part 230 of the shell assembly 200, and the speaker 100 is arranged in the sound cavity S; by directly installing the speaker 100 in the sound cavity S of the shell assembly 200, there is no need to place the speaker 100 in the box and then install the formed speaker 100 assembly on the shell 210, so that the volume of the sound cavity S of the speaker 100 can be expanded by omitting the speaker 100 box in a limited space, thereby increasing the sound quality of the speaker 100.

[0056] It should be noted that in the prior art, the housing 210 is provided with a mounting position for the speaker 100 assembly (speaker 100 + cabinet). However, due to the limitations of the overall layout of the display device, the reserved space is relatively small. Installing the cabinet in the reserved space will compress the volume of the sound cavity S of the speaker 100, making the sound cavity of the speaker 100 smaller after being installed on the cabinet. In the technical solution of the present application, the sound cavity S is directly formed on the housing assembly 200 within a limited space, thereby omitting the cabinet and directly installing the speaker 100 within the sound cavity S. This allows the volume of the sound cavity S to be expanded within the limited space, thereby increasing the quality of the speaker 100, especially the bass quality.

[0057] As an alternative to the above embodiment, as shown in FIG3 , the housing assembly 200 includes a housing 210 and a cover plate 220 . The housing 210 defines a sound cavity S, which has an opening O. The cover plate 220 is connected to the housing 210 and is provided at the opening O to seal the sound cavity S.

[0058] In this embodiment, the speaker 100 is installed in the sound cavity S and connected to the housing 210 by a cover plate 220, sealing the opening O of the housing 210. In this embodiment, the sound output hole of the sound output device 10 can be provided on the cover plate or on the housing 210. The first connecting portion 110 includes a first hook 111; the second connecting portion 230 includes a first connecting post 231, which is provided on the cover plate 220. The first hook 111 is connected to the first connecting post 231, thereby securing the speaker 100 in the sound cavity S.

[0059] In an embodiment, a wire outlet hole may be further provided on the housing 210 or the cover plate 220 for passing the speaker wire 130 of the speaker 100 . The speaker wire 130 is sealed with glue after passing through the wire outlet hole.

[0060] 1 to 6 , an embodiment provides a sound-emitting device 10. As shown in FIG5 , the speaker 100 includes a first hanging ear 111 and a second hanging ear 112. The first hanging ear 111 and the second hanging ear 112 are spaced apart from each other. The second connecting portion 230 includes a first connecting column 231 and a second connecting column 232, the first connecting column 231 being provided on the cover plate 220, and the second connecting column 232 being provided on the housing 210. The first hanging ear 111 is connected to the first connecting column 231, and the second hanging ear 112 is connected to the second connecting column 232, thereby installing the speaker 100 in the sound cavity S.

[0061] As shown in Figure 3, the housing 210 has a first side surface 211, which is disposed opposite the opening O. A second connecting post 232 is provided on the first side surface 211. During installation, the second mounting lug 112 can be first connected to the second connecting post 232, and then the first mounting lug 111 can be connected to the first connecting post 231 to secure the speaker 100.

[0062] As an optional implementation of the above embodiment, a first connection hole 1111 is formed on the first hanging ear 111; the first connection hole 1111 is sleeved on the first connecting column 231. As shown in Figure 6, a limiting buckle 2311 is provided on the first connecting column 231, and the limiting buckle 2311 abuts against the first hanging ear 111 to fix the first hanging ear 111 in the axial direction of the first connecting column 231. In some embodiments, the first connecting column 231 is provided with a plurality of limiting buckles 2311 arranged at intervals along the axial direction of the first connecting column; the first hanging ear 111 abuts against two adjacent limiting buckles 2311 at opposite ends in the first direction; wherein, the first direction is from the first side surface 211 to the opening O.

[0063] As shown in Figure 5, the first hanging ear 111 and the second hanging ear 112 are spaced apart along the X direction. The first side surface 211 and the opening O are arranged opposite to each other in the X direction. When installing the speaker 100, the speaker 100 can be embedded into the sound cavity S along the X direction, and the second hanging ear 112 is connected to the second connecting column 232. Then the first connecting column 231 is embedded in the first connecting hole 1111, and the first hanging ear 111 is positioned by two adjacent limiting buckles 2311 to fix the speaker 100. In addition, since the first connecting column 231 is provided with a plurality of limiting buckles 2311 spaced apart from each other along the first direction, speakers 100 of different lengths (X direction) can be set.

[0064] Furthermore, to facilitate connection, a second connection hole can also be provided on the second mounting ear 112, with the axial direction of the second connection hole along the X direction. A stopper 2311 can also be provided on the second connection post 232. During installation, the second connection post 232 is extended into the second connection hole, and the speaker 100 is then positioned using the stopper opening.

[0065] Referring to Figure 3 , from left to right in Figure 3 , the cover plate 220, speaker 100, and housing 210 are shown. During assembly, first insert the speaker 100 into the sound cavity S along the X-axis, so that the second connection hole on the second mounting lug 112 fits over the second connection post 232, and is positioned and secured by the stopper 2311 on the second connection post 232. Then, fit the first connection hole 1111 on the first mounting lug 111 over the first connection post 231, and push the cover plate 220 along the X-axis until it seals over the opening O.

[0066] In the embodiment, the cover plate 220 is ultrasonically welded to the housing 210. Since the exterior surface of the housing 210 is on one side of the sound outlet (i.e., on the side perpendicular to the X-axis), the welding area between the cover plate 220 and the housing 210 is located on the non-exterior surface.

[0067] In this embodiment, the X-direction is the length of the housing 210, which is the axial direction of the first connecting post. That is, the length of the speaker 100 is arranged parallel to the length of the housing 210, thereby fully utilizing the space in the housing 210 and expanding the volume of the sound cavity S within the limited space. In this embodiment, the number of limit buckles can be two or more, such as the two shown in Figure 6.

[0068] As an alternative embodiment to the above embodiment, the housing 210 further has a second side surface 212, which intersects with the first side surface 211 and extends from the end intersecting with the first side surface 211 to the opening O. The second side surface 212 is provided with a first sound outlet 11, and the sound outlet surface 120 of the speaker 100 is disposed opposite the first sound outlet 11. In this embodiment, the second side surface 212 extends along the X-direction, extending from the end intersecting with the first side surface 211 to the opening O.

[0069] For ease of description, the normal direction of the second side surface 212 is defined as the Y direction, and the X direction is perpendicular to the Y direction. In an embodiment, as shown in Figure 5, the sound-emitting surface 120 of the speaker 100 is located in the Y direction. The speaker 100 also has a Z direction, which is perpendicular to the X direction and the Y direction. When the speaker 100 is installed in the sound cavity S along the X direction, the sound-emitting surface 120 of the speaker 100 is close to the second side surface 212, so that the sound-emitting surface 120 of the speaker 100 is arranged opposite to the first sound outlet 11, and then emitted to the outside of the shell assembly 200 through the first sound outlet 11.

[0070] As an optional implementation of the above embodiment, the cover plate 220 is provided with a first wire outlet hole, through which the speaker wire 130 of the speaker 100 passes through the first wire outlet hole and exits the sound cavity S. In the embodiment, the first wire outlet hole is provided on the cover plate 220 to facilitate routing the speaker wire 130 out of the sound cavity S along the X direction.

[0071] In the embodiment, an air outlet is further provided on the cover plate 220 , and the air outlet is connected to the sound cavity S.

[0072] As shown in Figures 7 to 11 , another embodiment provides another sound-emitting device 10. This sound-emitting device 10 is similar to the sound-emitting device 10 shown in Figures 1 to 6 in that both utilize the sound cavity S on the housing assembly 200 to directly mount the speaker 100. Furthermore, as shown in Figure 8 , the sound-emitting device 10 includes a cover plate 220 and a housing 210. The housing 210 forms the sound cavity S, which has an opening O. The cover plate 220 covers the opening O, omitting the original cavity for mounting the speaker 100. However, the difference is that in this embodiment, the first connecting column 231 is provided on the cover plate, and the sound-emitting hole is provided on the cover plate 220 (for distinction, designated as the second sound-emitting hole 12 ). Furthermore, the orientation of the cover plate 220 (opening O) is different, the mounting orientation of the speaker 100 is different, and the mounting structure of the speaker 100 is different.

[0073] In this embodiment, there are at least two first mounting ears 111 and at least two first connecting posts 231. The first connecting posts 231 are connected to the first mounting ears 111 in a one-to-one correspondence. The at least two first connecting posts 231 are arranged in parallel. That is, in this embodiment, the cover plate 220 is provided with at least two first connecting posts 231. The extending direction of the first connecting posts 231 is parallel to the axial direction of the second sound outlet 12.

[0074] In an embodiment, the number of first connecting posts 231 on the cover plate 220 is determined based on the number of first hanging ears on the speaker 100. Typically, the number of first hanging ears on the speaker 100 is two, that is, the first connecting portion 110 includes two first hanging ears 111. If the number of hanging ears on the speaker 100 is three, the first connecting portion 110 also includes three first hanging ears 111, and the first connecting post 231 is provided with three first connecting posts 231, which are respectively connected to the first hanging ears 111. In an embodiment, a limiting buckle 2311 can be provided on the first connecting post 231; the first hanging ear 111 is provided with a first connecting hole 1111. The first connecting post 231 extends into the first connecting hole 1111, and the limiting buckle 2311 positions and fixes the first hanging ear 111. In an embodiment, the first connecting post 231 extends along the Y direction, so the axial direction of the first connecting hole 1111 of the first hanging ear 111 is parallel to the Y direction.

[0075] Optionally, the cover plate 220 is provided with a second sound outlet 12; the sound outlet surface 120 of the speaker 100 is arranged opposite the second sound outlet 12. In an embodiment, as shown in FIG9 , the cover plate 220 is provided with a second sound outlet 12. The sound outlet surface 120 of the speaker 100 is arranged opposite the second sound outlet 12.

[0076] The direction of the speaker 100 in the embodiments of Figures 7 to 11 is defined by the direction of the speaker 100 in Figure 5. That is, as shown in Figure 10, the X direction is the length direction of the shell 210, the Y direction is the axial direction of the sound outlet, and the Z direction is perpendicular to the X and Y directions. In this embodiment, as shown in Figure 9, the second sound outlet 12 is provided on the cover plate 220, and the cover plate 220 is provided at the opening O, that is, the cover plate 220 is provided in the Y direction. During installation, the first hanging ear 111 is connected to the cover plate 220 along the Y direction, and the sound outlet surface 120 of the speaker 100 is provided opposite to the second sound outlet 12, generally abutting against the cover plate 220. Then, the assembly formed by the cover plate 220 and the speaker 100 is installed inside the cavity along the Z direction.

[0077] That is, in this embodiment (Example 2), what is different from the structure shown in Figures 1 to 6 (Example 1) is that: Example 2 is installed along the Z direction, while Example 1 is installed along the X direction; in Example 2, there is no need to set a connecting structure on the shell 210 to fix the speaker 100.

[0078] In this embodiment, the housing 210 is provided with a second wire outlet hole (hereinafter referred to as the second wire outlet hole for distinction), through which the speaker wire 130 of the speaker 100 passes and exits the sound cavity S. The second wire outlet hole is provided on the wall of the sound cavity S along the X direction. An air outlet hole is also provided on the wall of the sound cavity S along the X direction.

[0079] In an embodiment, the cover plate 220 is welded to the housing 210 by ultrasonic welding.

[0080] In the above embodiment, the first and second mounting ears 111 and 112 are made of an elastic material. When the connecting post (the first and second connecting posts 231 and 232) are aligned with the first connecting hole 1111 extending therein, the first and second mounting ears 111 and 112 deform to hold the corresponding first and second connecting posts, thereby securing the speaker 100. For example, the first and second mounting ears 111 and 112 can be made of silicone.

[0081] As an optional implementation of the above embodiment, the shell 210 includes a first section 213 and a second section 214 connected to each other, and the first section 213 forms the sound cavity S. A support base 215 is integrally formed on the second section 214. In the prior art, the support base 215 is a plastic structure, which is fixed to the back panel of the display device, such as the back panel of a TV, by means of screws. In the embodiment of the present application, a support base 215 is integrally provided on the shell 210 to enhance the structural strength, further reduce the thickness of the back shell material to save the overall plastic consumption of the all-in-one integrated back shell, and reduce the amount of materials, which is beneficial to production management and production efficiency.

[0082] 4 and 8 , the support base 215 can be configured to form a sound cavity S, thereby fully utilizing the space of the housing 210. Furthermore, the support base 215 employs reinforcing ribs, which provide a certain structural strength and can improve the strength of the cavity structure of the sound cavity S.

[0083] For example, in the embodiment, the first side surface 211 is a side of the support base 215 , that is, the second connecting column 232 is disposed on the support base 215 , which can improve the structural strength of the second connecting column 232 and facilitate the fixation of the speaker 100 .

[0084] The present application also provides a display device including a sound output device 10. The specific structure of the sound output device 10 is similar to that of the above-described embodiments. Since the sound output device 10 utilizes all the technical solutions of all the above-described embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-described embodiments, and thus will not be described in detail here. The display device is typically a television, computer, or other device.
