Abstract

An active vibration damper includes a lower outer wall for placement on a floor, and front and rear outer walls, with the front and/or rear outer wall including first and second receptacles in an outer side thereof. The first receptacle receives a permanent magnet and is pot-shaped to maintain a closed configuration of the front and/or rear outer wall. A primary part of an electrical linear actuator is fixed at least on an inside of the lower outer wall, and a secondary part is arranged above the primary part and acted upon by the primary part. Retaining elements fixed to an inside of the upper outer wall movably hold the secondary part for displacement in a substantially linear manner in a left-right direction when the primary part is correspondingly impinged on. A magnetic back iron yoke is received in the second receptacle at the height of the secondary part.
