Speaker

摘要

A speaker includes a vibration system including a vibrating diaphragm and a flat voice coil for driving the vibrating diaphragm; a magnetic circuit system including a first magnet group, a second magnet group and a third magnet group, lined up in turn along the vibration direction of the vibration system; and a housing for accommodating the vibrational system and the magnetic circuit system. The first magnet group includes a first magnet and the second magnet with opposite magnetic poles thereof faced each other. The second magnet group includes a third magnet and a fourth magnet with N-pole of the third magnet close to S-pole of the fourth magnet. The third magnet group includes a fifth magnet and a sixth magnet with opposite magnetic poles thereof faced each other.

1. A speaker, comprising:
a vibration system including a vibrating diaphragm and a flat voice coil for driving the vibrating diaphragm; a magnetic circuit system including a first magnet group, a second magnet group and a third magnet group, lined up in turn along the vibration direction of the vibration system, the first magnet group including a first magnet and the second magnet with opposite magnetic poles thereof faced each other, the second magnet group including a third magnet and a fourth magnet with N-pole of the third magnet close to S-pole of the fourth magnet; the third magnet group including a fifth magnet and a sixth magnet with opposite magnetic poles thereof faced each other; a housing for accommodating the vibrational system and the magnetic circuit system; a magnetic gap formed by the gap between the first magnet and the second magnet, the gap between the third magnet and the fourth magnet, and the gap between the fifth magnet and the sixth magnet, for partially receiving the flat voice coil.
