Abstract: A vibration motor includes: a shell having an inner cavity; a vibrator; a magnetic component configured to drive the vibrator to vibrate; a first coil fixed to the shell; and a second coil fixed to the magnetic component. An alternating current applied to the first coil makes the vibrator to vibrate along the inner cavity.
