Abstract

A speaker is provided in the present disclosure. The speaker includes a shell, a magnetic system received in the shell for providing a magnetic gap, and a vibrating system. The vibrating system includes a membrane, a voice coil arranged in the magnetic gap for driving the membrane to vibrate, and a coil support for supporting the voice coil. The coil support includes a first connecting member and a second connecting member parallel to each other and connected to the membrane, the voice coil is fixed between the first connecting member and the second connecting member.

First claim

What is claimed is:

1. A speaker, comprising:
a shell;
a magnetic system received in the shell for providing a magnetic gap;
a vibrating system comprising a membrane, a voice coil arranged in the magnetic gap for driving the membrane to vibrate, a coil support for supporting the voice coil, and a dome attached on the membrane body of the membrane; the dome and the coil support are respectively arranged at two opposite sides of the membrane body;
wherein the coil support comprises a first connecting member and a second connecting member parallel to each other and connected to the membrane, the voice coil is fixed between the first connecting member and the second connecting member.

2. The speaker of claim 1 , wherein the first connecting member and the second connecting member provide a first fixing gap and a second fixing gap respectively, and two opposite ends of the voice coil are respectively fixed in the first fixing gap and the second fixing gap.

3. The speaker of claim 1 , wherein each of the first connecting member and the second connecting member comprises two parallel fixing parts and a connecting part connected between the fixing parts, and the connecting part is connected to the membrane.

4. The speaker of claim 3 , wherein each of the two fixing parts is in an elongated strip shape and comprises a connecting end, and the connecting part is connected between the connecting ends of the two fixing parts to form a U-shaped structure.

5. The speaker of claim 4 , wherein an end of the voice coil is sandwiched between the two fixing parts of the first connecting member, and an opposite end of the voice coil is sandwiched between the two fixing part of the second connecting member.

6. The speaker of claim 5 , wherein the voice coil is an oblate ring-shaped coil.

7. The speaker of claim 3 , wherein the membrane comprises a membrane body and a periphery surrounding the membrane body.

8. The speaker of claim 7 , wherein the connecting part of the coil support is connected to the membrane body of the membrane.

9. The speaker of claim 1 , wherein the magnetic system comprises a first magnet module and a second magnet module opposite to and apart from each other to form the magnetic gap.

10. The speaker of claim 9 , wherein each of the first magnet module and the second magnet module comprises two main magnets parallel to each other and a secondary magnet arranged between the two main magnets.

11. The speaker of claim 10 , wherein the two main magnets have opposite magnetized direction, and a magnetized direction of the secondary magnet is perpendicular to that of the two main magnets.

12. The speaker of claim 11 , wherein the two main magnets and the secondary magnet of the first magnet module are respectively opposite to the two main magnets and the secondary magnet of the second magnet module.

13. The speaker of claim 12 , wherein each of the two main magnets of the first magnet module has a magnetized direction same as a corresponding one of the two main magnets of the second magnet module.

14. The speaker of claim 13 , wherein the secondary magnet of the first magnet module has a magnetized direction opposite to the secondary magnet the second magnet module.

15. The speaker of claim 1 , wherein the shell comprises a front cover, a shell body and a rear cover, the shell body provides a receiving cavity for receiving the magnetic system and the vibrating system, and comprises a front opening and a rear opening; the front cover and the rear cover are engaged with a front end and a rear end of the shell body for covering the front opening and the rear opening.

16. The speaker of claim 15 , wherein the shell body is made of non-magnetic material or soft magnetic material.

17. The speaker of claim 15 , wherein the shell body comprises a top cover plate and a bottom cover plate opposite to each other, the top cover plate and the bottom cover plate are detachable from a main body of the shell body.

18. The speaker of claim 15 , wherein the rear cover comprises a bottom and a plurality of sidewalls perpendicularly extending from the bottom, the bottom comprises a plurality of air holes communicated with the receiving cavity of the shell body.
