ABSTRACT:
A vibration motor has an eccentric rotor having a plurality of armature coils with at least one winding-type air core armature coil disposed in an eccentric manner on a printed wiring board. A commutator is disposed on the printed wiring board. An eccentric weight is disposed so as not to overlap with at least one winding-type air-core armature coil and at least two of the air-core armature coils overlap. A magnet imparts a magnet field to the eccentric rotor via an axial air gap, a brush that imparts electric power to the air-core armature coils via the commutator.
