Abstract : The patent describes an electroacoustic transducer comprising an enclosing hollow piston element of relatively light rigid nonmagnetic material. A central vibratory mass element is situated within a piston element having opposite portions of magnetic material. The use of the piston-action vibrator unit eliminates complex modes of vibration, resulting in higher efficiency than ordinary diaphragm action.
