Abstract

The invention is a device for influencing the vibration of a planar element having two opposite surfaces and a neutral fiber plane running between the two surfaces including at least one actuator and at least one sensor which each are provided with transducer materials and are connected to at least one electronic component or an electronic module. The at least one actuator and at least one sensor are completely integrated into the planar element so as to be spaced from the two surfaces as well as from the neutral fiber plane.
