Abstract
A vibration motor is provided. The vibration motor includes a shell, a vibrating component disposed in the shell, coils secured in the shell and elastic connectors which are used to support the vibrating component elastically. The vibrating component comprises a mass block, a first magnet steel assembly and a second magnet steel assembly received in the mass block. The coils comprise a first coil disposed opposite to the first magnet steel assembly and a second coil disposed opposite to the second magnet steel assembly. The driving force generated by the first magnet steel assembly and the first coil can drive the vibration motor to vibrate along a first direction, while the driving force generated by the second magnet steel assembly and the second coil can drive the vibration motor to vibrate along a second direction, wherein the first direction and the second direction intersects to each other.
