Abstract

A speaker is disclosed. The speaker includes a magnetic circuit system; a vibration system including a vibrating diaphragm, a voice coil for driving the vibrating diaphragm, and a silicone gel spider elastically supporting the voice coil. The speaker further includes a high temperature resistant support ring attached with the voice coil and the silicone spider.

First claim

What is claimed is:

1. A speaker, comprising:
a frame and a front cover creating a receiving space with the frame:
a magnetic circuit system;
a vibration system including a vibrating diaphragm, a voice coil for driving the vibrating diaphragm, a silicone gel spider elastically supporting the voice coil; wherein
the speaker further includes a high temperature resistant support ring attached with the voice coil at an end far away from the vibrating diaphragm and the silicone spider;
the silicone gel spider includes a first internal circumferential part integrated with the support ring, a first external circumferential part fixed on the frame, and a first deforming part connected with the first internal circumferential part and the first external circumferential part, and the first deforming part extends in form of waves along a direction vertical to a vibration direction of the voice coil.

2. The speaker as described in claim 1 , wherein the support ring is integrated with the silicone gel spider by injection molding.

3. The speaker as described in claim 1 , wherein the support ring is made of polyimide.

4. The speaker as described in claim 1 , wherein the vibrating diaphragm comprises a middle top dome and a silicone gel edge ring connected with the middle top dome on the second internal circumferential part, the middle top dome is stacked-up with the second internal circumferential part, and the voice coil is fixed with the middle top dome at an end close to the vibrational diaphragm.

5. The speaker as described in claim 4 , wherein the middle top dome is made of aluminum.

6. The speaker as described in claim 4 , wherein the silicone gel edge ring comprises a second external circumferential part integrated by injection molding with the front cover, and a second deforming part connected with the second internal circumferential part and the second external circumferential part for creating elastic deformation, and the second deforming part extends in form of waves along a direction vertical to the vibration direction of the voice coil.

7. The speaker as described in claim 1 further including a gasket located between the front cover and the frame.

8. The speaker as described in claim 7 , wherein the front cover is provided with a wire outgoing hole, the voice coil comprises a voice coil wire and the voice coil wire is connected electrically with an external circuit through the wire outgoing hole.
