[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker main box or subwoofer box has a built-in power amplifier, which amplifies the audio signal and then plays back the sound, making the sound louder. Speakers are widely used in homes and public places such as shopping malls. In addition to preventing dust, the speaker grille also protects the speaker unit.

[0003] The disclosure discloses a mounting structure of a speaker grille, comprising a speaker body and a grille, wherein the surface of the speaker body is provided with a mounting groove and four cylindrical grooves in sequence from the outside to the inside, and the four cylindrical grooves are distributed at the four corners of the mounting groove, the grille comprises a main frame, a convex frame and a dustproof net, and the convex frame is welded on a side wall of the main frame, the dustproof net is embedded on the inner wall of the main frame, and convex columns are arranged at the four corners of the convex frame. The utility model realizes that the convex column cooperates with the cylindrical groove, the card block is connected with spring one, and the sliding frame connected with the card block is connected with spring two. After the convex column enters the cylindrical groove, the card block clamps it, so that the grille is installed, and then the two L-shaped rods are separated by squeezing the pull rod, so that the sliding frame drives the card block away from the convex column, and the convex column can be taken out from the cylindrical groove, so as to remove the grille, and the disassembly and assembly process is simple, thereby improving the flexibility and practicality of the grille.

[0004] In the above scheme, the four rubber strips on the mesh cover cooperate with the four rubber grooves respectively to achieve a sealing effect at the edges around the mesh cover, effectively preventing external water from seeping into the interior of the speaker from the edge gaps. However, the four rubber strips are installed by bonding. If the rubber strip is installed in a position that is offset from the rubber groove, the personnel will need to remove it and install it again. The operation is cumbersome and not convenient for quick replacement later. Summary of the invention
