An aim of development is creation of pre-production model of the generator of acoustic signals for marine seismic exploration, intended for rigging of scientifically-research ships and reconnaissance for seismo parties, that will allow to extend functional possibilities of existent technical equipments of seismic exploration and promote efficiency, exactness and informing of reconnaissance for seismo works on aquatoriums and shelf of pestilences. Research methods and apparatus are a mathematical design of processes in acoustic emitters induction - dynamic type taking into account the parameters of electric and mechanical subsystems of generator, receipt and treatment of experimental results in obedience to operating DSTU. Theoretical and practical results - it is worked out scientifically are technical principles of construction of electrodynamic sources of seismic waves and the pre-production model of generator of acoustic signals is made for marine сейсморозвідки of electrodynamic type in composition the high-voltage source of impulsive currents in a complete set with induction-dynamic acoustic transformers and the well-proven possibility of generuting of broadband acoustic impulses in the range of frequencies 400 Hz - 6,5 кНz, and by the low level of interference hindrances. A generator allows to conduct seismic researches and reconnaissance for seismo works in the mode of coherent accumulation of signals, to carry out the discrete adjusting of prevailing frequency in the spectrum of radiation in a range 1,4 - 6,5 кНz. Novelty - in theory and the experimentally well-proven possibility of creation of electrodynamic seismic sources on the basis of acoustic emitters induction - dynamic type with the discrete adjusting of prevailing frequency in the spectrum of radiation, including for deep-water researches. The effectiveness of the new application - application of the worked out generator allows to improve the discriminability of researches in 1,5 - 2 times, to extend functional possibilities of existent vehicle facilities of seismic exploration of aquatoriums. The field of application - seismic exploration of aquatoriums, realization of reconnaissance for seismo works and acoustic for seismo researches high-resolution. Methodology of creation of generators of acoustic and seismic signals on the basis of induction-dynamic acoustic transformers is basis for the construction of seismic sources for an engineering seismics, realization of researches of processes of change of soils, acoustic for seismo Antarctic researches, creation of seismic aerials of midfrequency seismic range with the guided diagram of orientation.
