  • Vibration member and vibration wave driving apparatus
    Patent number: 6943481
    Abstract: The present invention has been devised in order to raise driving efficiency of the vibration wave driving apparatus. A vibration member of a vibration wave driving apparatus of the present invention comprises the vibration member constituted of an elastic member and an electro-mechanical energy conversion element, and a rotor contacting the vibration member, and the vibration member generates a travelling wave in the elastic member when an alternating signal is applied to the electro-mechanical energy conversion element, in which an electrode film provided on a surface of the electro-mechanical energy conversion element of the vibration member is divided into a plurality of circular areas with different radiuses and each circular area is divided into a plurality of electrodes along its peripheral direction.
