We examine an energy harvesting system of two magnetopiezoelastic oscillators coupled
by electric circuit and driven by harmonic excitation. We focus on the effects of synchronization and
escape from a single potential well. In the system with relative mistuning in the stiffness of the harvesting
oscillators, we show the dependence of the voltage output for different excitation frequencies.
