An apparatus and a method for the excitation and/or damping and/or detection of structural oscillations of a plate-shaped device by means of a piezoelectric strip device are described. The apparatus comprises a carrier device (), at a distance from which the plate-shaped device () is disposed by way of a space (), wherein the piezoelectric strip device () includes a plurality of piezoelectric strip elements (), which each are connected to the carrier device () and to the plate-shaped device (), wherein the strips () can be excited into longitudinal changes, thereby causing the excitation and/or damping and/or detection of structural oscillations of the plate-shaped device (), and wherein the piezoelectric strips () are configured and connected to the plate-shaped device () such that the transmission of oscillations takes place in a substantially punctiform manner.
