发明名称 Ultrasonic motor and electronic device using the same
摘要 The present invention provides an ultrasonic motor including a wire having a coiled stator at one end thereof, a vibration generating device disposed at another end of the wire, a moving member that is in contact with the stator, a guide member that guides the rotation of the moving member, and an elastic member that covers the periphery of the wire. Accordingly, the driving efficiency of the ultrasonic motor that has a simple structure and that can be easily downsized can be enhanced and the performance stability thereof can be realized.
