HYDROACOUSTIC RECEIVER FOR FLEXIBLE EXTENDED TOWED ANTENNA Russian patent published in 2024 - IPC H04R1/44 

FIELD: hydroacoustic equipment.

SUBSTANCE: invention relates to hydroacoustic equipment, in particular to piezoelectric sound receivers of a geodesic seismic cable, intended for recording and measuring an acoustic field in water, used in geophysics for monitoring. Result is achieved by the fact that the hydroacoustic receiver is proposed, in which the sensitive element is made of N cylindrical piezoelectric elements, N≥3, coaxially arranged and connected in series through dielectric washers, and inner electrodes of cylindrical piezoelectric elements are connected to each other by means of additionally introduced elastic contact electrical connectors fixed in holes on projections of dielectric washers.

EFFECT: high sensitivity of the piezoelectric receiver and manufacturability thereof with a small inner diameter of annular piezoelectric elements.
