COMPOSITE ELECTROACOUSTIC TRANSDUCER Russian patent published in 2022 - IPC H04R31/00 C04B35/491

Abstract RU 2768297 C1

FIELD: instrumentation.

SUBSTANCE: invention relates to instrument making and concerns designs of composite electroacoustic transducers containing piezoceramic active elements. Composite electroacoustic transducer includes a unit of active piezoceramic elements made of piezoceramic material TsTStBS-2, connected to each other by their end surfaces using a layer of cured epoxy adhesive containing inorganic dispersed filler. Filler includes piezoceramic material of lead zirconate-titanate system. Epoxy adhesive filler also includes piezoceramic material TsTStBS-2.

EFFECT: higher efficiency of the transducer due to improved electrophysical characteristics.
