[0020] The utility model provides a kind of heat dissipation structure.

[0021] Referring to Figure 1 In an embodiment of the present application, the heat dissipation structure comprises a shell 10, a loudspeaker assembly 20 and a heat dissipation net 30. One side of the shell 10 is open 11. The loudspeaker assembly 20 is arranged in the shell 10, and the loudspeaker assembly 20 is arranged towards the open 11 side. The heat dissipation net 30 covers the open 11 position, and the loudspeaker assembly 20 communicates with the external environment through the heat dissipation net 30.

[0022] The shape of the shell 10 can be adjusted according to specific requirements. In this embodiment, a cubic structure is taken as an example, and a control circuit such as a circuit board is arranged at the bottom of the shell 10 to avoid occupying too much space.

[0023] The shell 10 is a hollow structure, and has a containing cavity inside for mounting the loudspeaker assembly 20. One side of the shell 10 is open 11, and when the loudspeaker assembly 20 is mounted in the shell 10, its face is arranged towards the open 11 side.

[0024] In addition, in this application, the open 11 is covered by the loudspeaker assembly 20, that is, the loudspeaker assembly 20 directly communicates with the external environment, thereby improving the heat exchange rate and improving the heat dissipation effect.

[0025] A layer of heat dissipation net 30 is further arranged outside the loudspeaker assembly 20. The surface of the heat dissipation net 30 is in a mesh structure, which avoids blocking the loudspeaker assembly 20 and the external environment. At the same time, the heat dissipation net 30 can protect the loudspeaker assembly 20, avoiding damage caused by direct contact between external equipment and the loudspeaker assembly 20.

[0026] Further referring to Figure 2 Two or more loudspeaker assemblies 20 can also be arranged in the shell 10. In this embodiment, two loudspeaker assemblies 20 are taken as an example for illustration. The opposite sides of the shell 10 are designed as open 11, and each open 11 is covered by a heat dissipation net 30. The two loudspeaker assemblies 20 are arranged opposite to each other, and the sound emitting side of each loudspeaker assembly 20 is arranged towards the corresponding heat dissipation net 30.

[0027] The loudspeaker assembly 20 is composed of a loudspeaker 21 and a basket 22. The size and shape of the basket 22 are matched with the size and shape of the open 11. The edge of the basket 22 is connected with the edge side wall of the open 11, thereby sealing the containing space in the shell 10.

[0028] Specifically, the basin frame 22 is annular, has a mounting hole 223 in the middle, and the loudspeaker 21 is fixed in the mounting hole 223. The outer ring edge of the basin frame 22 has a flange 221, which is parallel to the side wall of the shell 10. When installed, the flange 221 is attached to the side wall of the shell 10, thereby clamping the basin frame 22 and the loudspeaker 21 in the shell 10, or fixed by screws or other connecting members.

[0029] In order to improve the sealing effect, a sealing ring is arranged between the flange 221 and the side wall of the shell 10, which is made of rubber material. The gap between the basin frame 22 and the shell 10 is filled by the sealing ring to prevent external dust and water from entering the shell 10.

[0030] The basin frame 22 is annular, has a mounting hole 223 in the middle for accommodating the loudspeaker 21, and the edge of the loudspeaker 21 is connected to the edge of the mounting hole 223. The raised rib patterns are formed on the annular surface of the basin frame 22 by stamping or other methods, thereby forming the reinforcing ribs 222. Please refer to Figure 3 The reinforcing ribs 222 are raised towards the side of the heat dissipation net 30. By arranging the reinforcing ribs 222, on the one hand, the contact area between the basin frame 22 and the external environment can be increased, and the heat exchange efficiency can be improved. On the other hand, the connection strength of the basin frame 22 can be improved, and the stability of the loudspeaker 21 during use can be improved.

[0031] The number of reinforcing ribs 222 can be set to multiple. In this embodiment, since the basin frame 22 is annular, multiple reinforcing ribs 222 can be arranged along the circumference of the basin frame 22.

[0032] Please refer to Figure 4 The heat dissipation net 30 specifically includes a ventilation part 31 covering the opening 11. The ventilation part 31 is mesh-shaped and has multiple small ventilation holes. The loudspeaker 21 can directly communicate with the external environment through the mesh holes.

[0033] The size and shape of the ventilation part 31 are matched with the size and shape of the opening 11. The edge of the ventilation part 31 is provided with an inwardly bent connecting part 32, which is parallel to the side wall at the position of the opening 11. When assembled, the connecting part 32 abuts against the side wall at the opening 11 to clamp the heat dissipation hole, or fixed by screws or other connecting members.

[0034] In addition, the ventilation part 31 and the connecting part 32 are integrally formed to improve the connection strength therebetween and improve the stability of the user during use.

[0035] The utility model discloses still propose a kind of sound box, the sound box includes the heat dissipation structure as above, the specific structure of the heat dissipation structure refers to above embodiment, since the present sound box has adopted all technical solutions of above all embodiments, therefore at least have all beneficial effects brought by the technical scheme of above embodiment, here no longer one by one elaboration.

[0036] The above is only exemplary embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structural transformation made by using the utility model specification and drawing contents, or direct / indirect application in other related technical fields is included in the patent protection range of the utility model.
