Abstract

The present disclosure relates to a speaker and a magnetic circuit system thereof. The speaker includes a housing and at least one magnetic circuit system and at least one vibration system arranged in the housing. The at least one vibration system includes at least one layer of drive circuit configured to generate mechanical motion under the action of a magnetic field of the at least one magnetic circuit system, and a diaphragm driven by the at least one layer of drive circuit. The at least one layer of driving circuit is mounted to the diaphragm and has a planar shape. Since the driving circuit of the vibration system has a planar shape, the thickness of the speaker of the present disclosure can be effectively reduced.
