Abstract
A vibration motor is provided in the present disclosure. The vibration motor includes a housing, a magnet module received in the housing and fixedly connected with the housing, the magnet module comprising a main magnet unit as well as a first vice magnet unit and a second vice magnet unit symmetrically disposed on two sides of the main magnet unit, and the main magnet unit being spaced from the first vice magnet unit and the second vice magnet unit to form magnetic gaps, a vibration module, comprising a coil inserted into the magnetic gaps and masses for clamping the coil, and an elastic support, configured for connecting the coil and the masses to suspend the vibration module in the housing. A stop module for limiting the amplitude of the masses is disposed between the masses and the first vice magnet unit and between the masses and the second vice magnet unit.
