Beschreibung
Zusammenfassung:	A cryogenic cooler includes a housing, and first, second, and third actuators. The first actuator includes at least one first voice coil and at least one first magnetic circuit, the at least one first voice coil of the first actuator configured to drive a compressor piston, the first actuator causing vibrations to the housing when driving the compressor piston. The second actuator includes at least one second voice coil and at least one second magnetic circuit, the at least one second voice coil of the second actuator configured to reduce the vibrations to the housing caused by driving the compressor piston. The third actuator includes at least one third voice coil and at least one third magnetic circuit, the third actuator configured to drive a displacer piston. The compressor piston, balance mechanism, and displacer piston are concentrically formed within the cryogenic cooler.
