Piezo-Electric Transducers For Audible Bands
(AREA)
Abstract
FIELD: physics, acoustics.SUBSTANCE: low-frequency electroacoustic transducer comprises active element in the form of spring installed in body. Spring is made of piezoelectric plates that operate on bend vibrations and is fixed by its one end on body. Transducer is equipped by additional spring from piezoelectric plates with rigidity that does not exceed rigidity of the main spring and is connected by its one end to the main spring, and with its other end - to transducer body.EFFECT: higher limit emitted power.4 dwg
