Abstract
The invention relates to a device for the production of a haptic feedback from keyless input units such as touchscreens or keypads in mobile IT devices such as mobile telephones, PDAs, music or multimedia players, cameras, navigation devices, etc. The market demands a device which can produce a haptic signal for a touchscreen such that the display is movable as a whole essentially perpendicular to the housing surface at least in one direction. In order to resolve this object the invention provides for a device for the production of a haptic feedback from a keyless input unit, whereby the device has an elastic, essentially plate-shaped substrate, which at least comprises a first support location for fixing the substrate on a structure of the input device and at least a second support location for fixing the substrate on the input unit, and is formed to support the input unit movably with respect to the structure of the input device, whereby a piezoelectric element between the first and second support locations of the substrate is arranged in such a manner that with an electrical drive to the piezoelectric element one of the support locations is moved transverse to the plane of the plate-shaped substrate.
