1. A method for generating vibrations, comprising the steps of:

  • a) providing a magnetostrictive rod actuator having first and second ends;

    b) spring biasing a first base member having high magnetic permeability against the first end of the actuator, the first base member being in contact with the actuator and having a mass substantially equal to or less than the mass of the actuator; and

    c) rapidly varying a magnetic field through the actuator and first base member to cause the actuator to expand and contract, thereby vibrating the first base member along a longitudinal axis of the actuator.
