Appeal No. 96-2871
Application 08/352,964
claims 1 through 15, all claims pending in the application.
Appellants’ invention relates to a noise absorbing cover
for an automotive loudspeaker to prevent exterior noise from
being coupled through a loudspeaker to the interior of the
automobile.
Representative independent claim 1 is reproduced as
follows:
1. A vehicle comprising:
a structural panel disposed between an interior and
an exterior of said vehicle and including an aperture having
an axis;
a speaker mounted to said structural panel
substantially coaxially with said aperture, said speaker
having a front surface acoustically coupled with said interior
and a rear surface acoustically isolated from said interior;
and
a first sound absorbing barrier defining a space
substantially enclosing a rear of said speaker and defining an
air gap for venting said space to said exterior, said air gap
substantially preventing pressurization of said space, and
said air gap being oriented to exclude direct sound
transmission paths for exteriorly generated noise to said
interior.
