Abstract
The present invention provides a vibration motor with a closed-loop magnetic circuit, comprising a motor body, which further comprising: a stator fixed seat, a stator yoke, and a flexible circuit board; a mover, further comprising: a mover carrier, a magnet; and a mover yoke; and a suspension device, further comprising: an elastic support element and a fixed element. The flexible circuit board provides a current to the coil group, and cooperates with a magnetic field of the mover generated by the magnet to form an electromagnetic thrust to move the mover; and the stator yoke forms a stator yoke projection surface on the magnet surface of the corresponding magnet, and the area of the stator yoke projection surface is smaller than the area of the corresponding magnet surface.
