Patent ID: 7919945

Claim:
A vibration device, comprising: a base member; a plurality of actuators being coupled to the base member and including: a first actuator having a first member and a second member, the first member thereof being operatively coupled to a first portion of the base member, and the second member thereof being moveable relative to the first member of the first actuator, and a second actuator having a first member and a second member, the first member thereof being operatively coupled to a second portion of the base member, and the second member thereof being moveable relative to the first member of the second actuator; and means for synchronously vibrating at least the first and second ones of the plurality of actuators; wherein the plurality of actuators further includes a third actuator having a first member and a second member, the first member thereof being coupled to a third portion of the base member, the second member thereof being moveable relative to the first member of the third actuator, and the first, second and third actuators being oriented such that the vibration device is operable to generate a three dimensional combined vibration force.
