Abstract

The present disclosure provides a speaker, including a vibrating system and a magnetic circuit system driving the vibrating system to vibrate and sound, the magnetic circuit system includes a main magnet assembly, the main magnet assembly includes a first main magnet, a magnetic conductive piece and a second magnet which are arranged by stacking, poles of the first main magnet and the second main magnet having a same polarity are opposite to each other, the magnetic conductive piece includes a body portion clamped between the first main magnet and the second main magnet, and a clamping portion bending and extending from the body portion, the clamping portion includes a first clamping portion for fixing the first main magnet and a second clamping portion for fixing the second main magnet. The speaker provided by the present disclosure improves acoustic performance through providing the clamping portion on the magnetic conductive piece.

First claim

What is claimed is:

1. A speaker, comprising:
a vibrating system; and
a magnetic circuit system driving the vibrating system to vibrate and sound,
wherein the magnetic circuit system comprises a main magnet assembly, the main magnet assembly comprises a first main magnet, a magnetic conductive piece and a second magnet which are arranged by stacking, poles of the first main magnet and the second main magnet having a same polarity are opposite to each other, wherein the magnetic conductive piece comprises a body portion clamped between the first main magnet and the second main magnet, and a clamping portion bending and extending from the body portion, the clamping portion comprises a first clamping portion for fixing the first main magnet and a second clamping portion for fixing the second main magnet.

2. The speaker as described in claim 1 , wherein the first clamping portion and the second clamping portion have a same structure, both of which comprise an avoiding portion provided at a periphery of the body portion, an extending portion bended and extended from the avoiding portion in a direction perpendicular to the body portion, and a bending portion bended and extended from the extending portion in a direction towards a center of the body portion.

3. The speaker as described in claim 2 , wherein the bending portion is parallel to the body portion.

4. The speaker as described in claim 2 , wherein a bending portion of the first clamping portion abuts with a surface of the first main magnet departing from the body portion so as to fix the first main magnet, a bending portion of the second clamping portion abuts with a surface of the second main magnet departing from the body portion so as to fix the second main magnet.

5. The speaker as described in claim 2 , wherein there is a plurality of first clamping portions, at least two first clamping portions are symmetrically provided at the body portion, there is a plurality of second clamping portions, at least two second clamping portions are symmetrically provided at the body portion.

6. The speaker as described in claim 1 , wherein the first main magnet and the second main magnet are respectively provided with an avoiding portion configured to avoid the clamping portion.

7. The speaker as described in claim 1 , wherein the magnetic circuit system further comprises a magnetic yoke, the main magnet assembly is assembled on the magnetic yoke, a position of the magnetic yoke corresponding to the clamping portion is provided with an avoiding notch for accommodating the clamping portion.

8. The speaker as described in claim 1 , wherein the first main magnet is connected with the magnetic conductive piece through gluing, the second main magnet is connected with the magnetic conductive piece through gluing.

9. The speaker as described in claim 1 , wherein the magnetic conductive piece is a soft magnet.
