Abstract

The present invention relates to the technical field of electro-acoustic products. Provided is a loudspeaker module, comprising a first cover ( 10 ) and a second cover ( 20 ) combined together; the first cover ( 10 ) and the second cover ( 20 ) enclose an inner cavity of the module; the inner cavity of the module houses a loudspeaker unit ( 30 ) therein; the loudspeaker module further comprises a fastener assembly used to fasten to a fixed structure of an electronic device and thus fix the loudspeaker module to the electronic device. The loudspeaker module solves the technical problem in the prior art of insecure engagement between a loudspeaker module and an electronic device. The loudspeaker module is securely engaged with the electronic device and is easy to install, thus effectively extending the service life of the electronic device installed with the loudspeaker module.

First claim

What is claimed is:

1. A loudspeaker module, comprising:
a first cover;
a second cover, wherein the first cover and the second cover enclose an inner cavity of the module and the inner cavity of the module houses a loudspeaker unit therein; and
a fastener assembly, which is used to fasten to a fixed structure of an electronic device so that the loudspeaker module is fixed on the electronic device,
wherein the fastener assembly comprises a plurality of fasteners capable of performing straight reciprocating motion, and
wherein each of the fasteners comprises:
a fastener body disposed in the inner cavity of the module;
a fastening part disposed on the fastener body and extending orthogonal to the fastener body, wherein the fastening part passes through the top of the first cover along the entire path of straight reciprocating motion, the exposed end thereof is used to fasten to the fixed structure of the electronic device, and a motion clearance for the fastening part is provided on the first cover; and
wherein one end of each fastener is a press part, and an opposing end of each fastener is a connection part,
wherein the press part passes through the second cover, and
wherein the fastener assembly further comprises a spring connecting the connection parts.

2. The loudspeaker module according to claim 1 , wherein a first through hole is disposed on the top of the first cover for the fastening part to pass through, and wherein the motion clearance is provided between the edge of the first through hole and the fastening part passing therethrough.

3. The loudspeaker module according to claim 2 , wherein the extending directions of the connection part and the press part are both same as that of the fastener body, a second through hole is disposed on a sidewall of the second cover and at a position where the press part is located, and the press part passes through the second through hole.

4. The loudspeaker module according to claim 1 , wherein the fastener assembly comprises two fasteners, the two fasteners are symmetrically disposed, and the connection parts of the two fasteners are connected to two ends of the spring, respectively.

5. The loudspeaker module according to claim 4 , wherein the two fasteners are disposed on the inner side of the second cover through a fastener support.

6. The loudspeaker module according to claim 5 , wherein the fastener assembly and the loudspeaker unit are horizontally disposed side by side.

7. The loudspeaker module according to claim 4 , wherein when the loudspeaker module is fastened to the electronic device, the press parts of the fasteners exposed out of two opposite sides of the speaker module are pressed inwards, and the two fasteners compress the spring, so that the fastening parts of the fasteners are connected to the fixed structure of the electronic device, then forces exerted on the press parts of the fasteners are withdrawn, so that the fasteners are restored under expansion forces of the spring so as to be fastened to the fixed structure of the electronic device.
