Title: DRIVE CONTROL APPARATUS, ELECTRONIC DEVICE, AND DRIVE CONTROL METHOD
Abstract:
This invention addresses the problem of providing a drive control apparatus, an electronic device, and a drive control method that can provide good tactile feedback. This drive control apparatus drives a first vibrating element in an electronic device that has a display panel, a touch panel provided on the display-surface side of said display panel, and the aforementioned first vibrating element, which vibrates an operation surface via which operations are inputted to the touch panel. Said drive control apparatus has a drive control unit that drives the vibrating element using a drive signal that produces ultrasonic resonance in the touch-operation surface. Said drive control unit drives the vibrating element so as to change the intensity of the ultrasonic resonance in accordance with the amount of movement of the location of an operation input to the operation surface.
