摘要： An actuator including an electrically conducting coil arranged on or integrated into a wall member, wherein the electrically conducting coil is arranged adjacent to a magnetic flux return structure. A magnet connected to a carrier, wherein the magnet interacts with the electrically conducting coil such that when a current is applied to the coil the coil is either moved towards the carrier along an axial direction or away from the carrier along the axial direction depending on a direction of the current within the coil. A magnetic flux guiding structure connected to the carrier, wherein magnetic flux is guided through the flux return structure and the flux guiding structure.
