Classification: CPC H  B | IPC H

Claim 7:
8. A vibration motor, comprising
a housing;
a vibrator including at least one first magnet and at least one second magnet;
a first coil fixed to the housing to provide a driving force to the at least one first magnet such that the driving force causes the vibrator to vibrate in a first direction;
a second coil fixed to the housing to provide a driving force to the at least one second magnet such that the driving force causes the vibrator to vibrate in a second direction that crosses the first direction;
a first repulsion mechanism that causes repulsion between the housing and the vibrator in the first direction and configures the vibrator to move in the second direction; and
a second repulsion mechanism that causes repulsion between the housing and the vibrator in the second direction and configures the vibrator to move in the first direction,
wherein the first repulsion mechanism includes a first support member that supports the vibrator within the housing and includes:
a first deformation portion configured to undergo an elastic deformation in response to vibrations of the vibrator in the first direction, and
a first engagement portion that is engaged with the vibrator such that the vibrator is configured to produce a sliding motion associated with vibrations of the vibrator in the second direction.
