Abstract
An acoustic conduit provides a waveguide for coupling a loudspeaker inside a vehicle to a region outside the vehicle, or vice versa. The acoustic conduit includes a proximal opening configured to accommodate the loudspeaker. A distal opening is configured to acoustically couple to an exterior of the vehicle. The acoustic conduit defines an interior volume between the proximal opening and the distal opening and is configured to provide waveguide acoustic coupling between the loudspeaker and the exterior.
