1. A vibration damping apparatus comprising:

  • a cuboidal support frame; and

    an actuator includinga proof-mass coupled to the cuboidal support frame for movement in six degrees of freedom, wherein at least one of the six degrees of freedom is a translational degree of freedom;

    six permanent magnet pole pairs attached to a surface of the proof-mass or to a surface of the cuboidal support frame; and

    six coils each positioned opposite a corresponding one of the six permanent magnet pole pairs, each coil being associated with one of the magnet pole pairs such that a current flowing through the respective coil in the presence of a magnetic field of the respective pole pair induces a force that acts on the proof-mass.
