Patent ID: 8204244

Claim:
A spare wheel well cover comprising: a generally planar covering structure having a top surface and a bottom surface, such that: the covering structure divides a listening volume comprising an interior of the vehicle from a spare wheel well volume comprising space bounded by the spare wheel well and the covering structure, and containing the spare wheel, when the spare wheel well cover is secured to the spare wheel well, the top surface forms a portion of an interior surface of the listening volume, and the bottom surface forms a portion of an interior surface of the spare wheel well volume; and an electro-acoustic transducer mounted in a first opening through the covering structure, the first opening passing through both the top surface and the bottom surface, such that: a first radiating surface of the electro-acoustic transducer radiates sound energy outward from the top surface and into the listening volume without intervening acoustic volumes formed by the covering structure, and a second radiating surface radiates sound energy outward from the bottom surface and into the spare wheel well volume without intervening acoustic volumes formed by the covering structure.
