1. A vibration apparatus comprising:
a vibrating body that has a tubular shape and includes a first opening end portion, a second opening end portion, and an outside surface and an inside surface with which the first opening end portion is connected to the second opening end portion;
a light transmissive body connected to the second opening end portion of the vibrating body; and
a piezoelectric vibrator provided in the vibrating body to vibrate a connection body of the light transmissive body and the vibrating body; wherein
the vibrating body includes a flange portion extending from the outside surface of the vibrating body toward an outside; and
the vibration apparatus further includes a driving circuit that is electrically connected to the piezoelectric vibrator, that vibrates the 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.
