FIELD: hydroacoustic equipment. SUBSTANCE: device has rod active member which comprises piezoelectric emitters and flexible passive insertions. In addition device has front and back cone covers, clamping bolt with nut, housing, which is designed as two identical cylinders. Flanges of cylinders are clamped by studs with space. Housing is connected to covers through sound-proof insertions, pressurizing ring gaskets. In addition device has membrane, cylindrical emitting envelope and inner filling. EFFECT: effective low-frequency operations, possibility of use in autonomous, non-attended devices, design of hydroacoustic antennas. 1 dwg
