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 a touch-operation surface via which touch 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 such that the intensity of the ultrasonic resonance varies in accordance with the location of touch-operation input to the touch-operation surface and the degree to which said location varies over time.
