PROBLEM TO BE SOLVED: To make it possible to double driving force by using plural vibration actuators by providing the device with a control circuit which synchronizes the generation of the driving force of the respective vibration actuators by making the phases of the respective driving frequency signals of the plural vibration actuators the same between the plural vibration actuators. SOLUTION: Amplified zero driving signals are supplied to both of the A phase signals of the vibration actuators 1A, 1B when switches 7, 8 are connected to a contact R and switches 9, 10 to a contact T. Amplified +π/2 driving signals are supplied to both of B phase signals. As a result, the respective vibration actuators A, B are synchronously driven and the approximately double driving force added up with the respective driving force is generated. On the other hand, when the switches 7, 8 are connected to a contact L, the approximately double driving force reverse in the driving direction is generated. When the switches 7, 8 are connected to the contact L and the switches 9, 10 to the contact S, the vibration actuators 1A, 1B are operated with the phases varied by π/2. |
