[0024] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0025] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0026] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0027] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] Reference Figure 1-4 The utility model provides a sound box that is easy to dissipate heat, including a shell 1, an amplifier component 2 and a panel 3. The panel 3 is installed on the shell 1 and is used to close the shell 1. The amplifier component 2 is placed in the shell 1 and is used to connect the working components of the sound box.

[0029] The housing 1 includes an upper plate 11 and a lower plate 12, two side plates 13 and a back plate 14, the upper plate 11 and the lower plate 12 are adjacent to and vertically arranged with the two side plates 13, and the back plate 14 is adjacent to and vertically arranged with the two side plates 13, the upper plate 11 and the lower plate 12. The upper plate 11 and the lower plate 12, the two side plates 13 and the back plate 14 enclose the housing 1 with an inner cavity 15, the panel 3 can be fixed in the inner cavity 15, and a speaker 31 is fixed on the panel 3, and the speaker 31 can be electrically connected to the power amplifier assembly 2.

[0030] The power amplifier assembly 2 is fixed in the inner cavity 15, and a plurality of interfaces 21 are provided on the power amplifier assembly 2, and the plurality of interfaces 21 are extended out of the back plate 14. It should be understood that the form in which the power amplifier assembly 2 is fixed in the inner cavity 15 is not limited, and it can be fixed by a card slot provided inside, or it can be bonded by a structural adhesive.

[0031] A plurality of heat dissipation holes 123 are provided at positions of the lower plate 12 corresponding to the power amplifier component 2. A heat dissipation frame 16 made of metal is provided above the heat dissipation holes 123 in the inner cavity 15. The heat dissipation frame 16 is formed by bending a metal sheet multiple times. The upper end of the heat dissipation frame 16 abuts against the lower side of the power amplifier component 2, and the lower side of the heat dissipation frame 16 abuts against the lower plate 12.

[0032] After the speaker has been working for a long time, the temperature of the circuit in the power amplifier component 2 will gradually increase. The heat dissipation frame 16 is in direct contact with the power amplifier component 2, so that the heat of the power amplifier component 2 can be quickly transferred to the heat dissipation frame 16. The heat dissipation frame 16 is a frame-shaped structure and corresponds to the position of the heat dissipation hole 123. The air entering the heat dissipation hole 123 can flow in the heat dissipation frame 16, so that the heat dissipation frame 16 can quickly cool down, which can better conduct the heat on the surface of the power amplifier component 2, reduce the temperature of the power amplifier component 2, and improve the heat dissipation efficiency.

[0033] As an embodiment, a plurality of air holes 161 are provided on both sides of the heat dissipation frame 16. The air holes 161 can quickly dissipate the air in the heat dissipation frame 16 into the inner cavity, and then gradually discharge it from the gaps driven by the assembled speaker, so that the local temperature of the power amplifier component 2 is not too high, thereby protecting the power amplifier component 2 from damage due to high temperature.

[0034] As an embodiment, a plurality of reinforcing ribs 18 are fixed in the inner cavity 15, and a threaded hole is provided on the end face of each reinforcing rib 18. A plurality of screws that can be threadedly connected in the threaded hole are inserted on the surface of the panel 3, so that the panel 3 and the outer shell 1 are fixed, wherein the position corresponding to the heat dissipation frame 16 in the inner cavity 15 is not provided with reinforcing ribs 18, so that the heat dissipation frame 16 can be easily fixed. Further, a square groove 121 is provided on the lower plate 12, and the square groove 121 is located below the power amplifier component 2. A hard alloy plate 122 is fixed in the square groove 121, and a heat dissipation hole 123 is provided on the hard alloy plate 122. On the one hand, the contact between the hard alloy plate 122 and the heat dissipation frame 16, which are both made of metal, can improve the heat dissipation efficiency of the heat dissipation frame 16. On the other hand, the hard alloy plate 122 can be used to reinforce the outer shell 1 to avoid the insufficient impact resistance of the outer shell 1 without the reinforcing rib 18 position. At the same time, a small area of ​​metal plate can also be used to avoid the use of metal in the entire outer shell 1 and increase the cost.

[0035] As an embodiment, rubber pads 124 are fixedly connected to both ends of the lower side of the lower plate 12. The height of the rubber pads 124 is not less than 5 mm. The rubber pads 124 can increase the height of the housing 1 and increase the air intake of the lower heat dissipation holes 123. Furthermore, a support rod 141 is fixed to one side of the back plate 14. Setting a higher rubber pad 124 easily leads to unstable placement of the speaker. Setting a support rod 141 can stably place the speaker.

[0036] The implementation principle of the utility model is: after the speaker works for a long time, the temperature of the circuit in the power amplifier component 2 will gradually increase, and the heat dissipation frame 16 is in direct contact with the power amplifier component 2, so that the heat of the power amplifier component 2 can be quickly transferred to the heat dissipation frame 16. The heat dissipation frame 16 is a frame-shaped structure and corresponds to the position of the heat dissipation hole 123. The air entering the heat dissipation hole 123 can flow in the heat dissipation frame 16, so that the heat dissipation frame 16 can quickly cool down, which can better conduct the heat on the surface of the power amplifier component 2, reduce the temperature of the power amplifier component 2, and improve the heat dissipation efficiency.

[0037] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0038] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
