Abstract
A motion amplifier () comprises piezoelectric diaphragm () and drive electronics () for applying a drive signal to the piezoelectric diaphragm. The motion amplifier preferably comprises (in addition to the piezoelectric diaphragm) a reaction mass () connected to the piezoelectric diaphragm; a reacted mass () connected to the piezoelectric diaphragm; and, a reacted mass spring () for resiliently carrying the reacted mass. Motion or displacement of the piezoelectric diaphragm () is amplified to produce a greater displacement or motion of an actuator region or surface () of the reacted mass ().
