1. An apparatus for generating mechanical oscillation, the apparatus comprising:

  • a frame;

    a first disc rotatably mounted to the frame to enable rotation about an axis and having a surface that extends radially from the axis of rotation;

    a plurality of permanent magnets disposed on or within the surface of the first disc in an alternating polar orientation and in a circular pattern concentric with the axis of rotation, each of the permanent magnets having a maximum lineal dimension parallel to the surface of the first disc that is substantially smaller than a radius of the circular pattern;

    a second disc translatably mounted to the frame adjacent the first disc and having a radially-extending surface disposed parallel to and adjacent the surface of the first disc; and

    a plurality of permanent magnets disposed on or within the surface of the second disc in an alternating polar orientation and in a circular pattern concentric with the axis of rotation of the first disc such that, as the first disc is rotated with respect to the second disc, the permanent magnets of the first and second discs move cyclically between attractive and repulsive positions with respect to one another to cause the second disc to translate cyclically toward and away from the first disc.
