ABSTRACT:
A vibration control apparatus capable of efficiently generating vibrations of different orders using the same electrodes. A plurality of electrodes polarized to have desired polarities are formed in a piezoelectric element, and are divided into a plurality of electrode groups each comprised of electrodes including two or more electrodes with different polarities. Phases and frequency of alternating voltages applied to the electrode groups are changed, thereby generating vibrations of different orders.
