Vibration actuator, method for manufacturing vibration actuator, lens barrel and camera |
摘要 |
A vibration actuator having excellent driving performance, a method for manufacturing the vibration actuator, a lens barrel and a camera. The vibration actuator is provided with: an electromechanical conversion element which converts an electric energy into a mechanical energy; an elastic body which generates vibration waves by oscillation of the electromechanical conversion element; a resin layer, which is formed of a conductive thermoplastic resin and bonds the electromechanical conversion element and the elastic body with each other; and a relatively moving member which is brought into contact with the elastic body with a pressure and is relatively moved to the elastic body by vibration waves. |
