发明名称 Acoustic generator, acoustic generation device, and electronic device
摘要 An acoustic generator according to one embodiment includes a piezoelectric element (exciter), a vibrating portion, and a plurality of dampers. The piezoelectric element receives an input of an electrical signal and is caused to vibrate. The piezoelectric element is mounted on the vibrating portion, and the vibrating portion is caused to vibrate by the vibration of the piezoelectric element. The dampers are integrated with the vibrating portion. The dampers are asymmetrically provided with respect to an axis of symmetry of a shape delineated by the outline of the vibrating portion, in a plan view of the vibrating portion from a side on which the piezoelectric element is mounted.
