Abstract
An electronic device that includes a top panel having a manipulation input surface, a position detector detecting a manipulation input, a vibrating element generating a vibration in the manipulation input surface; and a drive control part being configured to drive the vibrating element by using a driving signal causing the vibrating element to generate a natural vibration in an ultrasound-frequency-band in the manipulation input surface, the drive control part driving the vibrating element so as to vary an intensity of the natural vibration in accordance with the position of the manipulation input performed onto the manipulation input surface and a temporal change degree of the position, wherein a thickness of the top panel is set that makes a wavelength of a standing wave generated on the top panel shorter than a wavelength of a ultrasound wave in the air at a frequency of the driving signal.
