Vibratory linear actuator |
摘要 |
A vibratory linear actuator includes a stator with a magnetic pole surface, a movable member with a magnetic pole surface, an electromagnet arranged in one of the stator and the movable member, a permanent magnet arranged in the other of the stator and the movable member and a support unit for movably supporting the movable member so that the magnetic pole surface of the electromagnet can oppose the magnetic pole surface with a gap left therebetween. The actuator is designed to vibrate the movable member by supplying an electric current to the electromagnet. The support unit includes a fixed portion to be fixed to a housing for accommodating the actuator, and the stator is configured to be fixed to the support unit as the support unit is fixed to the housing. |
