    • The invention relates to a device (1) for generating electric energy from mechanical excitation oscillation, comprising a mechanical resonator (2) that has at least one resonance element and a support (5) to which the excitation oscillations can be transmitted. Said resonance element is connected to the support (5) on the fixing point (4) and can be elastically deflected in relation to the fixing point (4) on a deflection point (6) which is arranged at a distance from the fixing point (4). An actuating element is provided for adjusting the resonance frequency of the resonance element. Said deflection point (6) is drivingly connected to an electric generator (8). Said device (1) comprises a measuring device for producing a phase differential signal (Up) for the difference between the phase position of the oscillation of the support (5) and the phase position of the oscillation of the deflection point (6). An outlet of the measuring device is connected to the actuating element via a phase controller (21) in order to adapt the resonance frequency of the resonance element to the frequency of the mechanical oscillations of the support (5).
