The structure has a first elastic element (102) with one end section connected to a first mounting end (101). An inertial object is vibrated by the elastic force of the elastic element. A moving electrode (103) is attached to the inertial object. An electrode (105) which controls the effective stiffness is connected to the mounting end. A voltage source (104) generates an electrical force between the moving electrode and the stiffness control electrode which varies linearly with the displacement of the inertial object.
