Speaker and electronic device

Abstract

A speaker including a frame;a magnetic circuit system fixed to the frame, comprises a plurality of magnetic circuit devices connected to each with a magnetic gap;a vibration system driven by the magnetic to vibrator, comprises a diaphragm fixed to the frame and a plurality of voice coil assembly inserted into the magnetic gap drive the diaphragm vibrate jointly. the speaker can drive the diaphragm to vibrate and produce sound with a greater driving force, and the magnetic circuit system has a higher magnetic field. The efficiency makes the speaker have a better sound effect.
