Abstract

The present invention relates to a magnetic circuit system and a sound producing device. The magnetic circuit system comprises: a bowl-shaped frame provided with a support portion at a central location thereof; a first magnet and a first top plate sequentially disposed at a surface of the support portion; and a second magnet and a second top plate sequentially disposed at a surface of the support portion facing away from the first magnet, the S pole of the first magnet opposing the N pole of the second magnet. The bowl-shaped frame further has a side wall located at the periphery of the support portion and there is a gap between the side wall and each of the first magnet and the second magnet. Outer surfaces of the first top plate and the second top plate do not extend beyond end surfaces of the bowl-shaped frame enclosed and defined by the side wall.
