Zusammenfassung:piezoelectric actuator comprises a piezoelectric element comprising two stacked layers. The two stacked layers comprise: a piezoelectric layer, and a passive layer mounted to the piezoelectric layer. The piezoelectric layer is configured to deform in a longitudinal direction in response to application thereto of electrical signals generated based on the received sound signals, so that the centers of both layers deflect in a direction normal to the longitudinal direction.
