Abstract

A speaker is provided in the present disclosure. The speaker includes a membrane, a voice coil connected to the membrane, and a solder pad formed on the membrane. The membrane includes a conductive silicone portion and a non-conductive silicone portion. The voice coil includes a coil portion for driving the membrane to vibrate, and a line lead portion led out from an end of the coil portion. The line led portion is connected to the solder pad, and the solder pad is formed on the conductive silicone portion of the membrane. The conductive silicone portion is connected to an input terminal of the speaker to receive an electric signal for driving the voice coil.

First claim

What is claimed is:

1. A speaker, comprising:
a holder;
a yoke received in the holder
and a magnet received in the yoke;
a membrane comprising a conductive silicone portion and a non-conductive silicone portion;
a voice coil connected to the membrane; and
a solder pad integrated with the conductive silicone portion of the membrane by an injection process or a hot pressing process;
wherein the voice coil comprises a coil portion for driving the membrane to vibrate, and a line lead portion lead out from an end of the coil portion, the line lead portion is connected to the solder pad;
the membrane has two opposite long edges, two opposite short edges, and four curved edges, the four curved edges are arranged at four corners of the membrane;
the long edges and the short edges are connected end to end by four curved edges, respectively;
and the conductive silicone portion is connected with an input terminal of the speaker for receiving an electric signal for driving the voice coil.

2. The speaker of claim 1 , wherein at least one of the curved edges of the membrane is configured as the conductive silicone portion, the solder pad is arranged on the curved edge configured as the conductive silicone portion, and the long edges and the short edges are configured as the non-conductive silicone portion.

3. The speaker of claim 1 , wherein at least one of the long edges or the short edges of the membrane is configured as the conductive silicone portion; the solder pad is arranged on the long edge or the short edge configured as the conductive silicone portion, the curved edges are configured as the non-conductive silicone portion.

4. The speaker of claim 1 , wherein the conductive silicone portion and the non-conductive silicone portion of the membrane are formed by a same integrated injection molding process.

5. The speaker of claim 1 , wherein the conductive silicone portion and the non-conductive silicone portion of the membrane are formed by two independent injection molding processes respectively.

6. The speaker of claim 1 , wherein the conductive silicone portion is configured at one or more of the long edges, the short edges and the curved edges.

7. The speaker of claim 6 , wherein a main body of the membrane serves as the conductive silicone portion, and a gap formed at the main body by non-conductive silicone serves as the non-conductive silicone portion to provide electrical insulation.
