Active vibration dampening device of a vibrating element

Device has a yoke frame (4) that slides along an axis of displacement based on the effect of a magnetic field. The magnetic field is generated by a current conducted through a coil (1) and a magnetically permeable armature (5). The coil is displaced with respect to the armature due to forces corresponding to the magnetic field. The field is directed in an air gap situated between the armature and frame.
