transÂ·duÂ·cer. A device that converts energy from one form to another. transducer (tranzdooÂ´sur), n a device that is activated by power from one system and then supplies a different form of power to a second system; used to convert electric energy into mechanical energy in ultrasonic and sonic scalers.
An apparatus for conversion of mechanical energy to electrical energy having a piezo transducer (1), which is formed from two or more layers, and having a mass/spring system (2, 3, 4), which can oscillate, in a holder (5), which is caused (6) to oscillate mechanically when stimulated, which oscillations periodically deform the piezo transducer such that an alternating voltage occurs on the connecting wires (7) of the transducer.
