Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-6 As shown, a detachable dustproof mesh for the rear cavity of a speaker includes a fixing plate 5, a plastic ring 1, a dustproof sheet 2, and a sealing ring 4. The fixing plate 5 and the plastic ring 1 are integrally formed. The sealing ring 4 is located on the surface of the plastic ring 1. The dustproof sheet 2 is bonded between the plastic ring 1 and the sealing ring 4. The outer periphery of the plastic ring 1 extends outward and protrudes outward to form a locking ring 6 that matches the mounting position of the speaker. The inner wall of the locking ring 6 protrudes to form several locking blocks 9. The locking blocks 9 extend along the inner wall of the locking ring 6. The surface of the locking ring 6 is recessed inward to form several slots 7 that match the mounting position of the speaker. The fixing plate 5 and the locking ring 6 are recessed inward to form a locking groove 10. The surface of the fixing plate 5 is provided with several openings 8 that match the mounting position of the speaker.
