Coupled sonic waves localized on dislocations in a piezoelectric crystal are investigated. The frequencies of in-phase and counter-phase oscillations in a system of two dislocations are found out. It is shown that due to the intrinsic resonance the oscillation energy is alternately concentrated near one dislocation or the other. The complete or partial energy exchange occurs, provided there is an arbitrary weak coupling in the system. As the interaction is decreased, the energy exchange between the dislocations is only slowed down.
