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.

An electronic device comprising:
- 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 and 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 including an actuator comprising a piezoelectric disk coupled to a substrate, the substrate comprising an elastically deformable truncated disk wherein the elastically deformable truncated disk is truncated on each of two sides of a diameter.
