Man-machine interface device for controlling e.g. audio system, in fascia of motor vehicle, has generation device generating impacts on rigid support and activated by user, where generation device includes brusque action activation element

摘要

The device (8) has a generation device (14) for generating impacts on a rigid support (12) and activated by a user. A detection and localization device (16) detects and localizes the impacts generated on the support by detection of mechanical waves produced by the impacts in the support. The generation device includes a brusque action activation element (18) constituted by an elastically deformable push-button i.e. stud (24). A backlighting device includes light sources i.e. LEDs, placed behind the support for diffusing light through the activation element.
