Abstract
Official abstract text for this publication.
A device for actively influencing vibrations in a component, in particular vibrations in a component of a motor vehicle such as engine vibrations, for example. The device includes a sensor for detecting the vibrations, an actuator which acts on the component, and a regulation and control unit in which actuating signals may be generated from the sensor signals in order to adjust the actuator. The actuator is designed as an electrically actuatable piezoelectric actuator.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a component; and a device for actively influencing vibrations in the component, comprising: a first sensor including a microphone; a second sensor including a piezoelectric sensor configured for detecting the vibrations; an electrically actuatable piezoelectric actuator configured for acting on the component; and a regulation and control unit in which actuating signals are generated from sensor signals of one of the first sens…
