Abstract
An acoustic chamber formed in door of a vehicle includes a metal door inner panel having an aperture extending therethrough, and a door module secured in the aperture of the door inner panel. The door module includes an indentation and may be made of a polymer or a fibrous material. An interior door trim panel overlies the door module and a loudspeaker is secured between the interior door trim panel and the door module. The interior door trim panel may include a bulge opposing the indentation in the door module, with the loudspeaker located between the bulge and the indentation. A sealing element is secured between the door module and the interior door trim panel for defining an acoustic chamber between the door module and the interior door trim panel. The acoustic chamber enhances the performance of the loudspeaker, thereby allowing a smaller loudspeaker to be used.
