Abstract
(EN)
A vibrating structure (1) comprising: a piezoelectric film (12) that deforms in a surface direction by adding voltage; a frame member (10) connected to the piezoelectric film (12); a vibration unit (14) supported by the frame member (10) via a supporting unit (13) and vibrating in the surface direction as a result of the deformation of the piezoelectric film (12); and a connection member (15) that connects the piezoelectric film (12), the vibration unit (14), and the frame member (10). In the connection member (15), a first connection member (151) that connects the vibration unit (14) and the piezoelectric film (12) is arranged between the center of gravity for the vibration unit (14) and a second connection member (152) that connects the frame member (10) and the piezoelectric film (12).
