Abstract
A vibration actuator includes a vibrator including an elastic body and an electro-mechanical energy conversion element; a contact body provided so as to be brought into contact with the vibrator; a flexible printed board configured to feed power to the electro-mechanical energy conversion element; and a temperature detection unit provided on a region of the flexible printed board, in which the flexible printed board and the electro-mechanical conversion element overlap each other.
Claims12
A vibration actuator comprising:
- a vibrator including an elastic body and an electro-mechanical energy conversion element;
- a contact body provided so as to be brought into contact with the vibrator;
- a flexible printed board configured to feed power to the electro-mechanical energy conversion element;
