PIEZOELECTRIC TRANSDUCER AND SOUND-GENERATING DEVICE

摘要

A piezoelectric transducer useful for example as a sound source or a strain detector includes a ferroelectric liquid crystal sealed between two baseplates with electrodes and alignment layers on the inner facing surfaces of the baseplates. One of the baseplates is thicker than the other, or is of a different material, so that the two baseplates have different flexural rigidity.
