According to one embodiment, a apparatus for driving a capacitance-type actuator includes a first voltage source, a second voltage source, and a driver. The first voltage source outputs a first voltage to charge the capacitance-type actuator. The second voltage source outputs a second voltage to charge the actuator. The driver switches between first and second charges and first and second discharges. The first charge supplies the first voltage to the actuator. The second charge supplies the sum of the first voltage and the second voltage to the actuator. The first discharge emits a charge accumulated in the actuator and guides the charge to the second voltage source. The second discharge emits the charge accumulated in the actuator without guiding the charge to the second voltage source. |
