Abstract
A terminal device includes a touch panel and excitation piezoelectric elements. The excitation piezoelectric elements are attached to a touch panel, and generate standing-wave vibration in the touch panel to give a user a tactile sensation when the user has performed a touch operation on the touch panel. The terminal device further includes a pressurization piezoelectric element that is attached to the inner side of the touch panel than the excitation piezoelectric elements, and pressurizes the touch panel thereby changing the vibration mode of the standing-wave vibration including the position of antinodes of the standing-wave vibration.
