ABSTRACT:
A vibration motor having an elastic body which is conductive, first and second piezoelectric elements which are joined with the elastic body, which harmonically cause a longitudinal vibration mode and a bending vibration mode to be generated on the elastic body, and which produce elliptical movement on the output take off position of the elastic body, and a third piezoelectric element which is joined with the elastic body, and which converts the vibrations produced on the elastic body to electric signals.
