Abstract
Official abstract text for this publication.
A piezoelectric electroacoustic transducer is provided, including a three-dimensional structure, at least a piezoelectric element, and at least a membrane. The three-dimensional structure is formed to have a top portion and a side portion integrally connected to the top portion by press molding a plate. The side portion has at least a gap and is separated into a plurality of pillars by the at least a gap. The at least a piezoelectric element is disposed on the top portion, and the at least a membrane covers the at least a gap of the side portion. The piezoelectric electroacoustic transducer in the present disclosure is capable of being implemented as a loudspeaker or a microphone.
