Abstract
The present invention relates to an actuator unit which is designed to generate a haptic signal, having a piezoelectric actuator which is designed to change its extent in a longitudinal direction as a function of an electrical voltage, a mechanical amplifier which is designed to amplify the haptic signal by converting the change in extent of the piezoelectric actuator into a movement of the actuator unit, wherein the movement occurs in the longitudinal direction, and the movement of the actuator unit occurs over a distance which is longer than the change in extent of the piezoelectric actuator, and the longitudinal direction is the direction in which an extent of the piezoelectric actuator is largest.
