[0046] 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 + box), but due to the limitation of the overall layout of the display device, the reserved space is small, and the arrangement of the box in the reserved space will compress the volume of the sound cavity S of the speaker 100, so that the sound cavity of the speaker 100 after being installed on the box is smaller. In the technical solution of the present application, the sound cavity S is directly formed on the housing assembly 200 in a limited space, so as to omit the box and directly install the speaker 100 in the sound cavity S, thereby expanding the volume of the sound cavity S in a limited space to increase the quality of the speaker 100, especially the bass quality.

[0047] As an optional implementation of the above embodiment, Figure 3 As shown, the housing assembly 200 includes a housing 210 and a cover plate 220. The housing 210 has a sound cavity S, and the sound cavity S has an opening O. The cover plate 220 is connected to the housing 210 and is provided with the opening O to cover the sound cavity S.

[0048] In the embodiment, the speaker 100 is installed in the sound cavity S, and is connected to the housing 210 by the cover plate 220, so as to close the opening O of the housing 210. In the embodiment, the sound outlet of the sound emitting device 10 can be set on the cover plate or on the housing 210. The first connecting portion 110 includes a first hanging ear 111; the second connecting portion 230 includes a first connecting column 231, and the first connecting column 231 is arranged on the cover plate 220; the first hanging ear 111 is connected to the first connecting column 231, so as to fix the speaker 100 in the sound cavity S.

[0049] 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.

[0050] Reference Figures 1 to 6 As shown, the embodiment provides a sound output device 10. Figure 5 As shown, 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 arranged at intervals 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 is arranged on the cover plate 220, and the second connecting column 232 is arranged 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, so that the speaker 100 is installed in the sound cavity S.

[0051] Reference Figure 3 As shown, the housing 210 has a first side surface 211, and the first side surface 211 is arranged opposite to the opening O. A second connecting column 232 is arranged on the first side surface 211. During installation, the second hanging ear 112 can be connected to the second connecting column 232 first, and then the first hanging ear 111 can be connected to the first connecting column 231, so as to fix the speaker 100.

[0052] 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 connection column 231. Figure 6 As shown, the first connecting column 231 is provided with a limiting buckle 2311, 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.

[0053] Reference Figure 5As shown, the first hanging ear 111 and the second hanging ear 112 are arranged at intervals 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 arranged at intervals along the first direction, speakers 100 of different lengths (X direction) can be set.

[0054] Further, for the convenience of connection, a second connecting hole can also be provided on the second hanging ear 112, and the axial direction of the second connecting hole is along the X direction. A limiting buckle 2311 can also be provided on the second connecting column 232. During installation, the second connecting column 232 is extended into the second connecting hole, and then the speaker 100 is positioned through the limiting opening.

[0055] Reference Figure 3 As shown, in Figure 3 From the perspective, from left to right are the cover plate 220, the speaker 100 and the housing 210. During assembly, the speaker 100 is first inserted into the sound cavity S along the X direction, so that the second connection hole on the second hanging ear 112 is sleeved on the second connection column 232, and is positioned and fixed by the limit buckle 2311 on the second connection column 232. Then, the first connection hole 1111 on the first hanging ear 111 is sleeved on the first connection column 231, and the cover plate 220 is pushed along the X direction until the cover plate 220 is sealed at the opening O.

[0056] In the embodiment, the cover plate 220 and the housing 210 are welded by ultrasonic plastic welding. Since the exterior surface of the housing 210 is on one side of the sound outlet (ie, on the side perpendicular to the X direction), the welding area between the cover plate 220 and the housing 210 is located on the non-exterior surface.

[0057] In the embodiment, the X direction is the length direction of the housing 210, which is the axial direction of the first connecting column. That is, the length direction of the speaker 100 is arranged parallel to the length direction of the housing 210, so as to make full use of the space of the housing 210 and expand the volume of the sound cavity S in a limited space. In the embodiment, the number of limit buckles can be 2 or more, such as Figure 6 Two shown.

[0058] As an optional implementation of the above embodiment, the housing 210 further has a second side surface 212, the second side surface 212 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 arranged opposite to the first sound outlet 11. In the embodiment, the second side surface 212 is formed to extend along the X direction, and extends from the end intersecting with the first side surface 211 to the opening O.

[0059] For ease of description, the normal direction 8 of the second side surface 212 is defined as the Y direction, and the X direction is perpendicular to the Y direction. Figure 5 As shown, the sound outlet 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 outlet surface 120 of the speaker 100 is closely attached to the second side surface 212, so that the sound outlet surface 120 of the speaker 100 is arranged opposite to the first sound outlet hole 11, and then the sound is emitted to the outside of the housing assembly 200 through the first sound outlet hole 11.

[0060] As an optional implementation of the above embodiment, the cover plate 220 is provided with a first outlet hole, and the speaker wire 130 of the speaker 100 passes through the first outlet hole to exit the sound cavity S.

[0061] In the embodiment, an air outlet is further provided on the cover plate 220 , and the air outlet is connected to the sounding cavity S.

[0062] like Figure 7 As Fig.11 As shown, the embodiment provides another sound emitting device 10, which is similar to the above-mentioned Figures 1 to 6 The same thing about the sound-emitting devices 10 shown is that they all use the sound-emitting cavity S on the housing assembly 200 to directly mount the speaker 100. Figure 8 As shown, the sound-emitting device 10 includes a cover plate 220 and a shell body 210. The shell body 210 forms a sound-emitting cavity S. The sound-emitting cavity S has an opening O. The cover plate 220 covers the opening O, and the cavity for originally installing the speaker 100 is omitted. The difference lies in that: in this embodiment, the first connecting column 231 is arranged on the cover plate, the sound-emitting hole is arranged on the cover plate 220 (named as the second sound-emitting hole 12 for distinction), and the setting orientation of the cover plate 220 (opening O), the installation orientation of the speaker 100, and the installation structure of the speaker 100 are different.

[0063] In the embodiment, the number of the first hanging ears 111 is at least two, and the number of the first connecting pillars 231 is at least two; the first connecting pillars 231 and the first hanging ears 111 are connected one by one. The at least two first connecting pillars 231 are arranged in parallel. That is, in the embodiment, at least two or more first connecting pillars 231 are arranged on the cover plate 220. And the extension direction of the first connecting pillar 231 is parallel to the axial direction of the second sound outlet 12.

[0064] In the embodiment, the number of the first connecting posts 231 on the cover plate 220 is determined according to the number of the first hanging ears on the speaker 100. Generally, the number of the 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 three first connecting posts 231 are provided on the first connecting post 231, which are respectively connected to the first hanging ears 111. In the embodiment, a limiting buckle 2311 may 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 the 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.

[0065] 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 to the second sound outlet 12. Fig. 9 As shown, the cover plate 220 is provided with a second sound outlet 12. The sound outlet surface 120 of the speaker 100 is arranged opposite to the second sound outlet 12.

[0068] In this embodiment, the housing 210 is provided with a second wire outlet hole (named as the second wire outlet hole for distinction), and the speaker wire 130 of the speaker 100 passes through the second wire outlet hole 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. The air outlet hole is also provided on the wall of the sound cavity S along the X direction.

[0069] In an embodiment, the cover plate 220 is welded to the housing 210 by ultrasonic welding.

[0070] In the above embodiment, the first hanging ear 111 and the second hanging ear 112 are made of elastic material, and when the connecting column (the first connecting column 231 or the second connecting column 232) is connected to the first connecting hole 1111 extending therein, the first hanging ear 111 and the second hanging ear 112 are deformed to hold the corresponding first connecting column and the second connecting column, thereby fixing the speaker 100. For example, the first hanging ear 111 and the second hanging ear 112 can be made of silicone.

[0071] 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 pronunciation 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 a display device, such as 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 rear shell material to save the overall plastic usage of the all-in-one integrated rear shell, and reduce the number of materials, which is beneficial to production management and production efficiency.

[0072] Furthermore, in the embodiments, Figure 4 and Figure 8 As shown, the support base 215 can be configured to construct the sound cavity S to fully utilize the space of the housing 210. In addition, the support base 215 uses reinforcing ribs and has a certain structural strength, which can improve the strength of the cavity structure of the sound cavity S.

[0073] 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 .
