VIBRATION APPARATUS AND IMAGING APPLIANCE

摘要

A vibration apparatus includes a plate-shaped dust prevention member, a vibration application member, and an electrode. The vibration application member includes a flexible thin plate-shaped piezoelectric member, and vibrates the dust prevention member. The electrode formed of a conductive thin plate or film, disposed to part or entire holding the piezoelectric member, and partly extends outward relative to the dust prevention member.

主权项

1. A vibration apparatus comprising:
a plate-shaped dust prevention member including a light transmissive region having a predetermined area spread from a central portion in radial directions; a securing member disposed to have a predetermined gap between itself and the dust prevention member; a vibration application member fixed to a peripheral portion of the dust prevention member, including a flexible thin plate-shaped piezoelectric member, and configured to vibrate the dust prevention member; a support member disposed between the securing member and the dust prevention member or the vibration application member to surround a center of the dust prevention member; and an electrode formed of a conductive thin plate or film, disposed to partly or entirely holding the piezoelectric member, and partly extending outward relative to the dust prevention member.
