Integrated vehicle instrument panel speaker system
An integrated speaker/climate control system is provided for use in a passenger compartment for distributing sound to occupants of a vehicle. A centralized speaker unit comprises a housing having a plurality of speakers mounted therein. A first sound duct coupled to the centralized speaker unit carries sound generated from a first one of the plurality of speakers to the passenger compartment. A second sound duct coupled to the central speaker unit carries sound generated from a second one of the plurality of speakers to the passenger compartment. A climate control duct coupled to the first sound duct injects a conditioned airflow through the first sound duct and into the passenger compartment. A first vent passage couples an interior of the housing to a predetermined volume separately from the climate control duct.
1 . An integrated speaker sound duct system for use in a passenger compartment of a vehicle comprising:
a centralized speaker unit comprising a housing having a plurality of speakers mounted therein;
a first sound duct coupled to said centralized speaker unit for carrying sound generated from a first one of said plurality of speakers to said passenger compartment; and
a second sound duct coupled to said central speaker unit for carrying sound generated from a second one of said plurality of speakers to said passenger compartment.
2 . The system of claim 1 further comprising a climate control duct coupled to said first sound duct for injecting a conditioned air flow through a portion of said first sound duct and into said passenger compartment.
3 . The system of claim 1 further comprising a first vent passage for coupling an interior of said housing to a predetermined volume separately from said climate control duct.
4 . An integrated speaker/climate control system for use in a passenger compartment of a vehicle comprising:
a centralized speaker unit comprising a housing having a plurality of speakers mounted therein;
a first sound duct coupled to said centralized speaker unit for carrying sound generated from a first one of said plurality of speakers to said passenger compartment;
a second sound duct coupled to said central speaker unit for carrying sound generated from a second one of said plurality of speakers to said passenger compartment;
a climate control duct coupled to said first sound duct for injecting a conditioned air flow through said first sound duct and into said passenger compartment;
a first vent passage for coupling an interior of said housing to a predetermined volume separately from said climate control duct.
5 . The system of claim 4 wherein said central speaker unit comprises a woofer.
6 . The system of claim 5 wherein said woofer uses a cross beam for creating a second predetermined volume, said second predetermined volume comprises at least a portion of said housing.
7 . The system of claim 6 further comprising a third sound duct coupled to said central speaker unit for carrying sound generated from said woofer to said passenger compartment.
8 . The system of claim 4 wherein at least one sound duct extends to a rear region of said passenger compartment.
9 . The system of claim 4 wherein at least one sound duct extends to an instrument panel.
10 . The system of claim 4 wherein at least one sound extends to a center floor counsel.
11 . The system of claim 4 wherein at least one sound duct extends to an overhead counsel.
12 . The system of claim 4 wherein said first and second ducts each include a respective pass-through port for allowing passage of sound to said passenger compartment.
13 . The system of claim 12 wherein said pass-through ports include a vent, said vent moveable between an open position and a closed position.
14 . The system of claim 4 wherein said climate control duct includes at least one control valve for controlling said conditioned air flow to said first and second duct, said at least one control valve moveable between and an open and a closed position.
