Abstract
The invention relates to a haptic feedback device comprising a support which can be vibrated and of which a first face is coated with at least one layer for detecting the position of a user's finger. The device includes electromechanical actuators which are aligned along an edge of the support or the layer and which are capable of making the support and the layer vibrate at an ultrasonic resonance frequency. The support comprises on the second face thereof a set of stiffeners distributed over the whole of said second face and configured to make it more difficult to bend the support along an axis perpendicular to the stiffeners, the stiffeners being designed to produce an axial and uniform vibration mode for the support, all the antinodes of which are of substantially equal amplitude.
