A vibration actuator and a method for driving the vibration actuator can improve the user's tactile sensation. A plurality of tactile devices are attachable at different positions on a surface of a touch panel to vibrate the touch panel. A driver drives, in response to a touch detection signal representing a touch position from the touch panel, the plurality of tactile devices each using a driving signal having a predetermined driving frequency. Of the plurality of tactile devices, a tactile device closest to the touch position is operable as a master device, and a tactile device other than the master device is operable as a slave device. The master device and the slave device are driven using the driving signal having the driving frequency being a resonant frequency of the master device.
