Abstract

A piston transducer having a central longitudinal axis and at least one piston member and an active transducer section displaced from one another along the longitudinal axis. Movement of the active transducer section is generally in a plane perpendicular to the longitudinal axis and a series of lever arms couple the movement of the active transducer section into a corresponding axial movement of the piston member and which axial movement is with a uniform velocity across the radiating surface thereof. For two-sided radiation, another piston member and series of levers may be connected to the active transducer section.
