Abstract
An electronic device includes a base, a touch-sensitive input surface spaced from and moveable relative to the base, and an actuating arrangement between the base and the touch-sensitive input surface. The actuating arrangement is arranged to vary a force on the touch-sensitive input surface in response to detection of a touch event on the touch-sensitive input surface. The actuating arrangement includes an actuator including a piezoelectric disk coupled to a substrate that includes an elastically deformable truncated disk.
