Abstract
A method of controlling vibration of a dynamic surface includes providing at least one piezoelectric actuator in communication with the dynamic surface, and providing a mass over the at least one piezoelectric actuator so that the at least one piezoelectric actuator lies between the mass and the dynamic surface. The method includes sensing vibration of the dynamic surface, and activating the at least one piezoelectric actuator after sensing vibration of the dynamic surface for applying a counter force between the dynamic surface and the mass for reducing or controlling vibration of the dynamic surface.
