ABSTRACT:
A motion amplifier (22) comprises piezoelectric diaphragm (30) and drive electronics (26) for applying a drive signal to the piezoelectric diaphragm. The motion amplifier preferably comprises (in addition to the piezoelectric diaphragm) a reaction mass (34) connected to the piezoelectric diaphragm; a reacted mass (40) connected to the piezoelectric diaphragm; and, a reacted mass spring (50, 270) for resiliently carrying the reacted mass. Motion or displacement of the piezoelectric diaphragm (30) is amplified to produce a greater displacement or motion of an actuator region or surface (46) of the reacted mass (40).
