| 发明名称 | Device for actively influencing vibrations in a component | ||
| 摘要 | 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. | ||
