Abstract (en)

[origin: WO2022027248A1] A haptic feedback arrangement (1) comprising at least one haptic signal generating element (2) extending in a main plane (P1), and at least one actuator (3) coupled to the haptic signal generating element (2). The actuator (3) is configured to displace an area of the haptic signal generating element (2) in a direction (D1) perpendicular to the main plane (P1) by generating a transverse wave, the transverse wave propagating from the area and along a longitudinal axis (A1) of the haptic signal generating element (2). This solution allows one actuator to generate displacement of an element along its entire length or area by allowing a transverse wave to travel across that length or area, facilitating a reduction in the number of actuators necessary as well as constructive interference between multiple signals. The displacement may be induced at frequencies which allow efficient vibrations with regards to human sensitivity.
