Abstract
A vibration structure that includes a frame member having an opening therein; a vibration part within the opening in the frame member; a support part that connects the vibration part and the frame member and supports the vibration part within the opening in the frame member; a film that deforms in a planar direction in response to voltage application; and a connection member that connects the film to the vibration part and the frame member such that the vibration part vibrates in the planar direction when the film deforms in the planar direction.
Claims18
A vibration structure comprising:
- a frame member having an opening therein;
- a vibration part within the opening in the frame member;
- a support part that connects the vibration part and the frame member and supports the vibration part within the opening in the frame member;
- a film that deforms in a longitudinal direction in response to voltage application;
- and
- a first connection member that connects the film to the vibration part and a second connection member that directly connects the film to the frame member such that the vibration part vibrates in the longitudinal direction when the film deforms in the longitudinal direction.
