    • 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 (1), at a distance from which the plate-shaped device (10; 10a) is disposed by way of a space (11), wherein the piezoelectric strip device (2; 2a, 2b; 2a′, 2b′,2c; 2d, 2e, 2f; 2′; 2g, 2h; 2i, 2j; 2k, 2l, 2m; 2n) includes a plurality of piezoelectric strip elements (2; 2a, 2b; 2a′, 2b′,2c; 2d, 2e, 2f; 2′; 2g, 2h; 2i, 2j; 2k, 2l, 2m; 2n), which each are connected to the carrier device (1) and to the plate-shaped device (10; 10a), wherein the strips (2; 2a, 2b; 2a′, 2b′,2c; 2d, 2e, 2f; 2′; 2g, 2h; 2i, 2j; 2k, 2l, 2m; 2n) can be excited into longitudinal changes, thereby causing the excitation and/or damping and/or detection of structural oscillations of the plate-shaped device (10; 10a), and wherein the piezoelectric strips (2; 2a, 2b; 2a′, 2b′,2c; 2d, 2e, 2f; 2′; 2g, 2h; 2i, 2j; 2k, 2l, 2m; 2n) are configured and connected to the plate-shaped device (10; 10a) such that the transmission of oscillations takes place in a substantially punctiform manner.
