Abstract

The invention is a device and a method for eliminating vibrations of a mechanical structure with at least one electromechanical converter material that is actively connected to the mechanical structure and connected to an electrical circuit with at least one electrical impedance. The electrical circuit is connected to an interface, via which the at least one electrical impedance can be variably adjusted by wireless or wired communications with a control unit that is separated from the electrical circuit in which the electrical impedance features at least one variable ohmic resistor, inductive resistor or capacitor.
