[0036] Example 1

[0037] Please refer to Figures 1-6 The waterproof structure of the speaker includes the speaker 2 and the base 3;

[0038] The base 3 is installed on the inner wall of the cabinet 1, and a waterproof cavity 4 is formed between the base 3 and the cabinet 1; a first sound amplification hole 101 is provided on the cabinet 1, and the first sound amplification hole 101 is connected to the waterproof cavity 4.

[0039] The speaker 2 is mounted on the top of the base 3. The top of the base 3 has a second amplification hole 301, which is connected to the waterproof cavity 4. The sound-emitting part of the speaker 2 faces the second amplification hole 301.

[0040] In this embodiment, the base 3 is set on the inner wall of the cabinet 1. It should be noted that the cabinet 1 here includes the main body of the cabinet 1 and the cabinet door. When rainwater or other liquids enter the waterproof cavity 4 from the first amplification hole 101, since the speaker 2 is installed on the top of the base 3, the height of the second amplification hole 301 is higher than the position of the first amplification hole 101. Water will not flow through the second amplification hole 301 to the speaker 2, and water cannot flow through the base 3 into the cabinet 1. Finally, the water flows out again from the first amplification hole 101 to the outside of the cabinet 1. The waterproof structure of the speaker 2, through the waterproof cavity 4 formed by the base 3 and the inner wall of the cabinet 1, can prevent external water from entering the cabinet 1. Furthermore, the sound emitted by the speaker 2 passes through the second amplification hole 301, the waterproof cavity 4, and the first amplification hole 101 in sequence to reach the outside. Therefore, it will not affect the normal sound effect of the speaker 2.

[0041] Furthermore, the base 3 is provided with a sealing part 302 at one end close to the inner wall of the cabinet 1, and the base 3 is sealed to the inner wall of the cabinet 1 through the sealing part 302.

[0042] Furthermore, the sealing part 302 is provided with a sealing element, which is used to prevent water from flowing out from the gap between the sealing part 302 and the cabinet 1.

[0043] In this embodiment, by providing a sealing element between the sealing part 302 and the cabinet 1, it is possible to further ensure that the water in the waterproof cavity 4 will not flow out from the gap between the sealing part 302 and the cabinet 1.

[0044] Furthermore, the sealing element is a sealing ring 5, and the end face of the sealing part 302 that contacts the cabinet body 1 is provided with a first mounting groove 3021 that is connected to the end, and the sealing ring 5 is installed in the first mounting groove 3021.

[0045] In this embodiment, please refer to Figure 3 and Figure 4 The sealing element is a sealing ring 5; the sealing ring 5 is installed in the first mounting groove 3021, and the sealing ring 5 seals all four sides of the sealing part 302, ensuring that the water in the waterproof cavity 4 cannot flow out from any position between the sealing part 302 and the cabinet 1.

[0046] Furthermore, the sealing element is a sealing strip 6, and a second mounting groove 3022 is provided on the end face of the sealing part 302 that contacts the cabinet body 1. The sealing strip 6 is installed in the second mounting groove 3022, and the sealing strip 6 at least seals the bottom edge and both sides of the sealing part 302.

[0047] In this embodiment, please refer to Figure 5 and Figure 6The sealing element is a sealing strip 6. The sealing strip 6 is installed in the second mounting groove 3022, wherein the second mounting groove 3022 is at least opened on the bottom edge and both sides of the sealing part 302. It is possible that the second mounting groove 3022 must be opened on the bottom edge and both sides of the sealing part 302, while the top edge of the sealing part 302 may or may not be opened. Of course, the second mounting groove 3022 may also extend to the top of the sealing part 302. Compared with the above-mentioned solution using a sealing ring 5, the solution using a sealing strip 6 has a lower production cost. Furthermore, the sealing strip 6 at least seals the bottom edge and both sides of the sealing part 302. Therefore, water in the waterproof cavity 4 cannot enter the cabinet 1 from the bottom edge and both sides of the sealing part 302. Since the water in the waterproof cavity 4 will be discharged from the first sound amplification hole 101, the height of the top of the sealing part 302 is higher than the height of the first sound amplification hole 101. Therefore, the water level in the waterproof cavity 4 cannot reach the top of the sealing part 302.

[0048] Furthermore, the base 3 includes a pair of mounting parts 303, which are respectively located on both sides of the main body of the base 3. The base 3 is mounted on the inner wall of the cabinet 1 through the pair of mounting parts 303.

[0049] In this embodiment, the base 3 is installed on the inner wall of the cabinet 1 by means of the mounting parts 303 provided on both sides, and the sealing part 302 of the base 3 is tightly pressed against the inner wall of the cabinet 1.

[0050] Furthermore, the base 3 has a latching part 304 on its top, and the speaker 2 is mounted on the top of the base 3 through the latching part 304.

[0051] In this embodiment, the speaker 2 is mounted on the top of the base 3 via the snap-fit ​​part 304. Of course, the speaker 2 can also be mounted on the top of the base 3 in other ways, such as by bolts or screws.

[0052] Furthermore, at least two latching parts 304 are provided, and the latching parts 304 are respectively provided on both sides of the top of the base 3. A limiting part 305 is provided at the top of the base 3 away from the inner wall of the cabinet 1.

[0053] The first end of the speaker 2 is close to the limiting part 305, and the second end of the speaker 2 is close to the inner wall of the cabinet 1.

[0054] In this embodiment, the latching part 304 is used to restrict the horn 2 from moving in the left and right directions, and the inner wall surface of the cabinet 1 and the limiting part 305 are used to restrict the horn 2 from moving in the front and back directions, respectively.

[0055] Furthermore, multiple first loudspeaker holes 101 are provided, and the multiple first loudspeaker holes 101 are arranged in multiple rows and columns;

[0056] The second loudspeaker 301 is provided in multiple rows and columns.
