摘要：
A vibration motor includes a first resilient member and a second resilient member providing resilient forces in opposite directions; a first vibrator and a second vibrator coupled to the first resilient member and the second resilient member respectively; a magnetic body coupled to the first vibrator to create a magnetic field; and a coil applying a current of a predetermined frequency band in the region where the magnetic field is created.
