A MECHANICALLY AMPLIFIED PIEZOELECTRIC TRANSDUCER

摘要

A piezoelectirc transducer having a component therein for amplifying the deformation of the piezoelectric element so as to increase the available transducer stroke. This amplification of the piezoelectric element may be provided by a mechanical amplifier coupled to the piezoelectric element. The mechanical amplifier is configured to exert a preloading force on the piezoelectric element.
