Abstract
An acoustic generator according to an embodiment includes at least a plurality of piezoelectric elements (exciters) and a vibrating portion. The piezoelectric elements vibrate upon reception of input of an electric signal. The piezoelectric elements are attached to the vibrating portion. The piezoelectric elements are attached to the vibrating portion asymmetrically with respect to all the symmetry axes of a figure drawn by a contour of the vibrating portion when seen from the above.
