Conditions of slow acoustic electromagnetic waves propagation in piezocrystals and their association with volume acoustic waves have been considered. That kind of dependence between these waves is caused both linear and nonlinear piezoeffects. Dependencies between amplitudes of electric and magnetic fields, their polarizations in the waves and directions of propagation, polarization and amplitudes of acoustic waves have been obtained. Conditions of mutual transforming common electromagnetic waves into associated slow acoustic electromagnetic waves have been determined on the free surface of piezocrystals as well as for the reverse process. One can consider difficulties of the problem of double transforming of infrared laser radiation into the hypersound on the surface and vice versa process on the other side of piezocrystal.
