Vibration wave driving apparatus, vibration member and driving system for the vibration wave driving apparatus

A vibration member, comprising:

• an elastic member;
• and
• an electro-mechanical energy conversion element having a plurality of electrode regions which are fixed to the elastic member and polarized in the same direction, wherein the elastic member generates a travelling wave which is obtained by synthesizing a plurality of standing waves on a surface thereof by supplying an ac signal to the electro-mechanical energy conversion element;
• and
• a plurality of wiring members which are connected to the plurality of electrode regions of the electro-mechanical energy conversion element,
• wherein wiring members used for generating standing waves having the same phase among the plurality wiring members are arranged at intervals integer times the wavelength of the standing waves having the same phase.

A driving system for a vibration wave driving apparatus, comprising:

• a vibration wave driving apparatus which fixes an electro-mechanical energy conversion element having a plurality of electrode regions all of which are polarized in the same direction to an elastic member, and which generates a travelling wave which is obtained by synthesizing a plurality of standing waves different in phase on a surface of the elastic member by supplying an ac signal to the electro-mechanical energy conversion element;
• a signal supply circuit for generating the ac signal which is supplied to the electro-mechanical energy conversion element;
• and
• a plurality of wiring members which connect the signal supply circuit to the plurality of electrode regions of the electro-mechanical energy conversion element,
• wherein wiring members used for generating standing waves having the same phase among the plurality of wiring members are arranged at intervals integer times the wavelength of the standing waves having the same phase.
