DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example

[0021] In order to improve the waterproof effect of the speaker, a high-strength waterproof structure for waterproof speakers is designed. The specific solution is as follows:

[0022] like Figure 1-2 As shown, a high-strength waterproof structure for waterproof audio includes a box structure, the box structure adopts a sealing structure, the box structure is a plastic shell, the box structure includes a front plate 101, a main structure 1 and a rear plate 102, a speaker mounting hole and a pressure regulating hole 6 are opened on the front plate 101, a waterproof sound-permeable membrane is attached to the speaker mounting hole and the pressure regulating hole, a reinforcing rib structure 104 is provided in the box structure for reinforcing the strength of the box structure, waterproof glue is coated on the joints of various parts of the box structure, the rear edge of the waterproof glue is also coated with silica gel, the box structure is covered with a continuous waterproof membrane, and an outer shell is also installed on the outside of the box structure.

[0023] In this embodiment, the waterproof structure is an overall rectangular structure, which is used to manufacture a rectangular structure speaker. The front panel 101 and the main structure 1 are an integrated structure. During processing and manufacturing, the front panel 101 and the main structure 1 can be integrally formed, and the rear panel 102 can be disassembled. The joint position formed by the installation of the rear panel 102 and the main structure 1 is coated with waterproof glue, and the inner side of the joint position is coated with silicone.

[0024] The reinforcing rib structure 104 is a grid-like structure, and a triangular connection structure is provided at the position where the surfaces of the grid-like structure meet.

[0025] The reinforcing rib structure 104 is a continuous reinforcing rib on the inner wall of the front plate 101 and the main structure 1. Since the rear plate 102 can be removed, the reinforcing rib structure 104 on the rear plate 102 is an independent structure. After the rear plate 102 is installed, the reinforcing rib structure 104 on the rear plate 102 can be connected with other reinforcing ribs. The reinforcing rib structure 104 is used to improve the strength of the box structure. Even if it falls into water and is subjected to a certain pressure, the box structure can be kept from deformation, and water will not seep into the interior at the joint between the rear plate 102 and the main structure 1.

[0026] The outer shell is connected to the box structure by screws. The box structure is provided with an inner closed mounting screw hole 103. The inner closed mounting screw hole 103 can prevent water from seeping in from the mounting screw hole 103 when screws are installed. A plurality of mounting screw holes 103 are provided on the front panel 101 for installing an audio grille. A plurality of mounting holes are provided on the rear panel 102 for installing the rear panel 102. A plurality of mounting screw holes 103 for docking with the mounting holes are provided on the rear of the main structure 1.

[0027] In this embodiment, a large and a small speaker hole are opened on the front panel 101. The large speaker hole is a first speaker hole 5, and the small speaker hole is a second speaker hole 4. The two speaker holes are arranged one above and one below for installing speakers. A plurality of speaker mounting holes are opened on the edge of the speaker hole. When the speaker is installed, a fixing structure is also installed on the edge of the speaker, which not only plays a role in fixing the speaker, but also plays an aesthetic role. A pressure regulating hole 6 is opened symmetrically between the two speaker holes, and a waterproof sound-permeable membrane is provided on the pressure regulating hole 6.

[0028] The surface of the waterproof membrane is equipped with a super hydrophobic layer, which is used to quickly remove water droplets on the surface. When the speaker is exposed to rain or falls into water, after picking up the speaker, the water on the surface can be quickly removed, reducing the probability of water seeping into the inside, while keeping the speaker dry to avoid affecting its use.

[0029] The rear plate 102 is provided with a connection portion 2, on which a connection port 201 is provided. The connection portion 2 is an L-shaped hollow structure, and the connection port 201 is provided at the top of the hollow structure. In this embodiment, the connection portion 2 is provided at the lower part of the rear plate 102, and a space is reserved at the upper part of the rear plate 102 for installing the circuit compartment 3.

[0030] A waterproof plug 202 is provided on the connection port 201 . The waterproof plug 202 is movably connected to the rear plate 102 . The waterproof plug 202 is a rubber plug. One end of the waterproof plug 202 is fixedly connected to the rear plate 102 .

[0031] When the speaker is playing normally, in the rain, the connection port 201 will not be exposed to rain, and rainwater cannot flow to the connection port 201 to short-circuit the line. When the connection port 201 is not in use, the connection port 201 can be covered with a waterproof plug 202 for waterproofing. Each connection port 201 is equipped with a corresponding waterproof plug 202.

[0032] The box structure has a circuit cabin 3 built in. The surface of the circuit cabin 3 is provided with a finned heat sink for heat dissipation. The entire circuit cabin 3 is a closed structure. A waterproof sealing ring is provided at the wire entry and exit position on the circuit cabin 3.

[0033] The circuit cabin 3 includes two connectable shells. The circuit cabin 3 can be removed separately. The circuit cabin 3 is fixed to the inside of the box structure by screws. A circuit board fixing hole is provided in the shell of the circuit cabin 3, which is used to install screws to fix the circuit board in the circuit cabin 3; the box structure is also provided with a waterproof cover 7 for the speaker, and a waterproof cover 7 located on the inner side of the connection port 201. The waterproof cover 7 is also provided with heat dissipation fins. Even if water penetrates into the interior, the circuit cabin 3 and the waterproof cover 7 can prevent the main components inside the audio from short-circuiting. While playing a waterproof role, it does not hinder the heat dissipation of the components. The bottom of the waterproof cover 7 for the speaker is provided with a vent for air circulation.

[0034] The waterproof structure of the present solution adopts an integrated structure for the box structure except the rear panel 102, which reduces the presence of seams as much as possible and reduces the possibility of water seepage in the seams. The speaker and the pressure regulating hole 6 on the front panel 101 are covered with a waterproof sound-permeable membrane, which plays a waterproof role without affecting the sound of the speaker. The rear connection port 201 is provided with a waterproof plug 202. When the connection port 201 is not in use, it can be covered with the waterproof plug 202 to prevent the connection port 201 from getting wet and causing a short circuit when in use. Example

[0035] In this embodiment, the waterproof structure is substantially the same as that in Embodiment 1, except that the circuit compartment 3 and the waterproof cover 7 are eliminated, and the circuit board, the speaker, and the connection port 201 are exposed inside the box structure. Example

[0036] In this embodiment, the waterproof structure is basically the same as the structure in Embodiment 1, except that absorbent cotton is attached to the inner wall of the box structure, so that even if water penetrates, it can be absorbed to avoid the flow of water inside.

[0037] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
