Method and device for influencing the transfer of vibrations of a vibration generator to an object connected to it, in particular of engine vibrations to the body of a motor vehicle

A device for influencing the transfer of vibrations of a vibration generator to an object connected to it via an intermediate element, said device comprising:

• at least one actuator in the form of a piezo element, which can be induced to undergo controlled secondary vibrations;
• and
• a detector arranged in a region between the intermediate element and the object;
• wherein
• the actuator is arranged in the region between the intermediate element and the vibration generator;
• and
• the detector is arranged in the region between the intermediate element and the object.

A method for influencing the transmission of primary vibrations generated by a vibration generator to an object connected to the generator via an intermediate element, the method comprising:

• controlling an actuator positioned between the vibration generator and the intermediate element to generate secondary vibrations designed to cancel the vibrations generated by the vibration generator;
• measuring the vibrations at a point between the intermediate element and the object;
• and
• adjusting the secondary vibrations generated by the actuator based on the vibrations measured at the point between the intermediate element and the object to minimize the vibrations transmitted to the object through the intermediate element.
