Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, the dustproof sound panel formed by precise injection molding comprises a panel body 1, wherein a through hole 2 and an adjusting hole 3 are respectively formed in the surface of one side of the panel body 1, and the inner wall of the through hole 2 is horn-shaped;

furthermore, the penetrating port 2 is arranged in a horn shape, so that the internally arranged dustproof part can be better attached to the surface of the sound speaker;

the inner wall of the through hole 2 is provided with a dustproof part, the dustproof part comprises a dustproof circular ring 4, the outer surface of the dustproof circular ring 4 is hexagonal, and the outer surface of the lower end of the dustproof circular ring 4 is in threaded connection with the inner wall of the through hole 2;

further, the dust cannot be accumulated through the arc surface outside the dustproof ring 4.

A dustproof groove 5 is formed in the inner side wall of the upper end of the through opening 2, an annular disc 6 is fixedly connected to the outer surface of the middle of the dustproof circular ring 4, and an air bag 7 is fixedly connected to the lower surface of the annular disc 6;

furthermore, the peripheral side surface of the annular disc 6 is an arc-shaped surface, and the outer surface of the annular disc 6 is movably sleeved with the inner wall of the dust-proof groove 5;

further, it is achieved that by arranging the outer part of the annular disc 6 in an arc shape, the annular disc 6 does not cause unnecessary loss to the airbag 7 when pressing the airbag 7.

Further, the outer surface of the air bag 7 is in a convex shape, and the outer surface of the air bag 7 is in close contact with the inner wall of the dust-proof groove 5;

further, it is achieved that the gap between the annular disc 6 and the dust chute 5 is sealed by the close contact of the air bag 7 with the dust chute 5.

Through the arrangement of the dustproof component, the effect that dust is prevented between the sound loudspeaker and the panel body 1 through the dustproof component is achieved, and dust is prevented from entering the interior of the sound;
