Claim 12:
13. An input assembly, comprising:
a carrier,
an input part, which is mounted on the carrier in a manner capable of vibrating along at least one direction of movement by means of mounting means, the input part having an input surface intended to be touched by an operator and with a touch-detection device for detecting a touch upon the input surface by the operator, and
an electromagnetic actuator for exciting a movement of the input part along the direction of movement by means of an electric control signal in order to generate a haptic feedback for the operator in the case of a touch by the operator, wherein the actuator has an additional mass that is resiliently mounted using a resilient mount and the actuator is attached to the input part via a vibration isolator;
wherein a natural frequency of the vibrating system comprising the additional mass and its resilient mount is greater by a factor of A=√2 than a natural frequency of the vibration isolator.
