Zusammenfassung:	FIELD: measurement technology, primary transducers-energy converters, seismic prospecting, underwater acoustics, alarm systems detecting traveling targets. SUBSTANCE: piezomagnetic geophone has case housing three induction coils, three permanent magnets with formation of intermagnet distances X1 and X2 and two piezoceramic elements with straps. Permanent magnets and piezoceramic elements with straps are so positioned on one axis that center magnet is placed in magnetic suspension with flexibility C which allows it travel along axis within intermagnet distances X1 and X2. EFFECT: increased specific sensitivity and noise immunity. 1 dwg
