In an embodiment a mechanical reinforcing element includes two end regions, two angular regions, wherein the end regions are located at two opposite end faces of the reinforcing element, wherein each angular region connects to one of the end regions via a first joint, and wherein the angular regions have a stiffening structure, and a connecting portion interconnecting the two angular regions and connecting to the angular regions through second joints, wherein the mechanical reinforcing element is configured such that, upon a relative movement of the end regions with respect to each other, the connecting portion performs a movement perpendicular thereto.

Mechanical reinforcing element with two end regions and two angular regions

A device for generating a haptic signal. The device includes a haptic module for generating a vibration, a base plate and a cover plate arranged parallel to each other. The cover plate has an abutment surface facing towards the base plate and a top side facing away from the base plate. The haptic module is arranged between the base cover plates, a first partial area of the haptic module abuts the abutment surface of the cover plate and a second partial area of the haptic module abuts the base plate. A spring-loaded suspension mechanically connects the base plate and the cover plate. The spring-loaded suspension is designed so that the abutment surface of the cover plate is moved towards the base plate when the cover plate is in a neutral position and a force is exerted in the direction of the base plate on any point on the top side of the cover plate.

A device and a method for producing haptic feedback are disclosed. In an embodiment a device includes at least one piezoelectric actuator having a plurality of piezoelectric layers and internal electrodes arranged therebetween, a first amplification element and a second amplification element, wherein the piezoelectric actuator is arranged between the amplification elements, wherein the piezoelectric actuator is configured to change its extension in a first direction upon application of an electrical voltage, and wherein the amplification elements are configured to deform as a result of the change in the extension of the piezoelectric actuator such that a subregion of a respective amplification element is moved relative to the piezoelectric actuator in a second direction, which is perpendicular to the first direction and a driver circuit configured to apply the electrical voltage to the piezoelectric actuator such that the amplification elements are deformed thereby producing the haptic feedback against an object pressing on the device, the haptic feedback imitating a jump in force.
