Abstract: An electronic device has a touch screen, a protecting panel for protecting the touch screen by covering the touch screen, a vibration actuator coupled to the protecting panel to vibrate the protecting panel, and a control module for collecting location information of an input unit which touches the protecting panel, wherein the control module controls vibration characteristics of the vibration actuator according to a location of the input unit and forms a squeeze film between the input unit and the protecting panel to decrease a frictional force between the input unit and the protecting panel. The protecting panel has a visible area where the touch screen is exposed to be checked by the naked eyes, and an invisible area other than the visible area, and the vibration actuator is coupled to the invisible area.
