A drive system for driving a diaphragm pressure wave generator comprising opposed first and second diaphragms (11,13) that are each coupled at or toward opposite ends of a reciprocally moveable drive piston (19). The drive system comprises an operable actuator (27) that generates a reciprocating motion output having a low force and long stroke. The drive system also comprises a hydraulic amplifier that is operatively coupled between the actuator and the drive piston, the hydraulic amplifier being arranged to convert the reciprocating motion output from the actuator into an amplified output having a higher force and shorter stroke, and apply the amplified output to the drive piston (19) to cause the drive piston and opposed diaphragms (11,13) to reciprocate and generate waves. |
