A drive control device with improved operability is provided. Provided is a drive control device for driving a vibration element of an electronic device, the electronic device including a display unit, a top panel that is disposed on a display surface side of the display unit and has an operation surface, a coordinate detection unit for detecting the coordinates of an operation input performed on the operation surface, and the vibration element for causing vibrations on the operation surface. The drive control device includes: a storage unit which stores data associating arranged positions of a plurality of images, arranged on the display unit to implement mutually different functions when the operation input is performed, with vibration patterns of a drive signal that causes unique vibrations in an ultrasonic wave band to be generated on the operation surface in accordance with the degree of temporal change in the position of the operation input; and a drive control unit which selects the vibration pattern of the drive signal corresponding to the arranged position of the image including the position of an icon being dragged by the operation input, and which drives the vibration element, wherein the vibration patterns differ depending on the images. |
