A method of making a vehicle interior trim panel having at least one integral resonant bending wave loudspeaker panel, comprising designing the trim panel to comprise at least one panel area capable of and intended to operate as a resonant bending wave loudspeaker, making a prototype trim panel to the design, optimising at least one parameter of the prototype panel as concerns its behaviour as a resonant bending wave loudspeaker by obtaining the standard deviation, as frequency is varied, of the mechanical impedance of the panel as a function of the at least one parameter, selecting a value or values of said at least one parameter that result in a minimum of said standard deviation of the mechanical impedance of the panel, and making a trim panel in which the at least one parameter to be optimised has the selected value or values.
L'invention concerne un procédé de réalisation de panneaux de garnissage pour intérieur de véhicules, comportant au moins un panneau monobloc de haut-parleur à onde de flexion résonante. Ce procédé consiste à concevoir le panneau de garnissage afin qu'il comporte au moins une zone conçue pour fonctionner en tant que haut-parleur à onde de flexion, à réaliser un prototype du panneau de garnissage d'après la conception, à optimiser au moins un paramètre du panneau prototype concernant son comportement en tant que haut-parleur à onde de flexion résonante par l'obtention de l'écart type de l'impédance mécanique, au fur et à mesure que varie la fr
