摘要 |
Vibrating linear actuator and method of operating same. The actuator of the invention includes a stator, a spring vibration system having a moving portion with a magnet and further having a spring configured to support the moving portion. The actuator further includes an electromagnetic coil configured to receive an electrical current, whereupon the coil moves the moving portion against a load supplied by the spring to reciprocally move the moving portion, a frequency detector configured to detect a natural frequency of the spring vibration system, and a frequency controller configured to determine a frequency of an electrical current pulse, the pulse to be received by the coil, in accordance with a detection result of the detector. <IMAGE> |
