Abstract:
A vibration apparatus includes a vibrating body that has a tubular shape and includes first and second opening end portions, an outside surface, and an inside surface, a light transmissive body connected to the second opening end portion of the vibrating body, and a piezoelectric vibrator provided in the vibrating body. The vibrating body includes a flange portion extending from the outside surface of the vibrating body toward an outside. The vibration apparatus further includes a driving circuit that vibrates a connection body of the light transmissive body and the vibrating body in a vibration mode of light transmissive body vibration or a vibration mode of flange portion vibration and that alternately switches between the vibration mode of the light transmissive body vibration and the vibration mode of the flange portion vibration.
