Abstract
The invention is a vibration sensor with a carrying element capable of being set into vibration; a conversion device having a field coil to set and/or tap the carrying element into vibration; an anchor mounted in the field coil; and, a vibration element to transmit the vibrations from the carrying element into/from a surrounding space. The anchor is designed as two parts, having a permanent magnet and a coil core connected to the field coil, with an air gap arranged therebetween and lying in the area of the axial extension of the field coil. The permanent magnet is connected to the carrying element to transmit vibrations; and, the field coil and the permanent magnet are arranged to interact in such a way that any vibration of the permanent magnet induces current flow in the field coil and/or induces vibration of the permanent magnet in the field coil.
