Speaker assembly
A speaker assembly, includes: a housing with an accommodation space; a sound generator, and a sound aperture communicating the sound generator with an outside. A dustproof element is fixed by the housing and includes a first dustproof member, a pressing plate, and a second dustproof member attached to the pressing plate. The pressing plate includes a through hole aligned with the sound aperture, the through hole is completely covered by the second dustproof member. The housing includes at least two positioning protrusions located two sides of the sound aperture, and at least two melting posts extending along a protruding direction of the positioning protrusions. The pressing plate further includes two clip slots for engaging with the positioning protrusions. The positioning protrusion is located in the slip slot, and the pressing plate is fixed with the housing by the melted melting posts.
1. A speaker assembly, including:
a housing with an accommodation space;
a sound generator in the accommodation space, the sound generator including a diaphragm;
a sound aperture communicating the sound generator with an outside;
and a dustproof element fixed on the housing and completely covering the sound aperture, the dustproof element including a first dustproof member fixed on the housing and completely covering the sound aperture, a pressing plate abutting against the first dustproof member and fixed on the housing, and a second dustproof member attached to a side of the pressing plate away from the first dustproof member; wherein
the pressing plate includes a through hole penetrating therethrough and aligned with the sound aperture, the through hole completely covered by the second dustproof member;
the housing includes at least two positioning protrusions located on two sides of the sound aperture, and at least two melting posts extending along a protruding direction of the positioning protrusions;
the pressing plate further includes two clip slots recessed from two sides thereof toward the through hole for engaging with the positioning protrusions; and the positioning protrusions are located in the clip slots, and the pressing plate is fixed with the housing by the melting posts.
2. The speaker assembly as described in claim 1 , wherein the pressing plate further includes two first recesses respectively recessed from the two clip slots toward the through hole, and each melting post is disposed in the corresponding first recess.
3. The speaker assembly as described in claim 1 , wherein the housing includes a upper cover and a lower cover forming the accommodation space, the sound generator forms a front sound cavity with the upper cover, the upper cover forms a sound passageway communicating the front sound cavity with the sound aperture.
4. The speaker assembly as described in claim 1 , wherein at the same side of the sound aperture, a top of the melting post is higher than a top of the positioning protrusion.
5. The speaker assembly as described in claim 1 , wherein an outer surface of a top of each melting post includes a second recess located at a top surface of the corresponding positioning protrusion.
6. The speaker assembly as described in claim 5 , wherein at each of the two sides of the sound aperture, the pressing plate includes a third recess located at a side facing the second recess and recessing toward the through hole.
7. The speaker assembly as described in claim 6 , wherein at each of the two sides of the sound aperture, the second recess and the third recess cooperatively form a glue-slot for receiving a top of the melting post after the melting post is melted.
8. The speaker assembly as described in claim 7 , wherein each melting post located at a middle portion of the corresponding glue-slot.
9. The speaker assembly as described in claim 1 , wherein the first and second dustproof members both include dustproof meshes and frame for supporting the meshes.
