The interaction of anharmonic natural oscillations of a piezoelectric resonator has been investigated. The impact produced by the interaction of modes on generation of the frequency spectrum has been described. The obtained expressions allow for the evaluation of influence produced by the interaction of modes on frequency of the main mode.
