Patent

CA 2297104

A trim panel, e.g. a roof lining for a vehicle passenger compartment, characterised in that the trim panel comprises an integral acoustic radiator and a vibration exciter mounted on the radiator to launch bending waves into the radiator to cause it to resonate to produce an acoustic output, and means integral with the radiator to define the radiator periphery.

L'invention concerne un panneau de garniture, par exemple le revêtement du toit de l'habitacle des passagers d'un véhicule. Ce panneau de garniture comprend un élément rayonnant acoustique et un excitateur de vibrations, monté sur ledit élément rayonnant acoustique afin de pouvoir émettre des ondes de flexion dans ce dernier, et ainsi le faire résonner et produire une sortie acoustique. Des organes sont également intégrés à cet élément rayonnant acoustique afin de déterminer son contour.
