FIELD: aquatic organisms.
SUBSTANCE: acoustic emitter for luring marine hydrobionts includes a housing containing a frame made of plastic resistant to prolonged vibrations, a fairing with holes for cooling internal structures located around the frame, while at the perimeter of the frame there are at least three electromagnetic coils with cooling channels, operating, respectively, in three different frequency ranges of an equal power signal applied to them, fixed on magnetic cores with a gap, while a neodymium permanent magnet is placed in each magnetic gap of the magnetic cores, on which a mounting plate made of flexible plastic, while each mounting plate outside the emitter fairing is equipped with radiating plates, different from each other in shape and mass, made of sheet material resistant to sea or fresh water.
EFFECT: increased reliability of the emitter.
