Abstract

An illuminating speaker assembly for use in the passenger compartment of a vehicle includes a flat panel speaker for converting electrical audio signals into sound waves. The flat panel speaker utilizes a light-permeable, sound-producing panel. A light source is positioned within the flat panel speaker for generating light that passes through the light-permeable, sound-producing panel.

Claims

1. An illuminating speaker assembly for use in the passenger compartment of a vehicle, comprising:

a flat panel speaker including a light-permeable, sound-producing panel, for converting electrical audio signals into sound waves; and

a light source positioned within said flat panel speaker for generating light that passes through said light-permeable, sound-producing panel.

2. An illuminating speaker assembly according to claim 1 further comprising a controller for controlling the intensity of said light source.

3. An illuminating speaker assembly according to claim 1 wherein said light source comprises a plurality of light-emitting diodes.

4. An illuminating speaker assembly according to claim 3 wherein said plurality of said light-emitting diodes includes at least first and second groups, said first group for emitting light of a first color and said second group for emitting light of a second color.

5. An illuminating speaker assembly according to claim 4 wherein said plurality of light-emitting diodes further includes a third group of light-emitting diodes for emitting light of a third color.

6. An illuminating speaker assembly according to claim 5 wherein said first, second, and third colors are red, blue, and green, respectively.

7. An illuminating speaker assembly according to claim 5 further comprising a controller for individually varying the intensity of said first, second and third groups of light-emitting diodes to produce resultant light of a desired color.

8. An illuminating speaker assembly according to claim 7 wherein said controller comprises first, second, and third switches for varying the intensity of said first, second, and third groups of light-emitting diodes, respectively.

9. An illuminating speaker assembly according to claim 7 wherein said controller is a microprocessor.

10. An illuminating speaker assembly according to claim 3 wherein said plurality of light-emitting diodes is housed in at least one light-permeable tube.

11. An illuminating speaker assembly for use in the passenger compartment of a vehicle, comprising:

a flat panel speaker including a light-permeable, sound-producing panel, for converting electrical signals into sound waves;

a variable color light source positioned within said flat panel speaker for generating light which passes through said light-permeable, sound-producing panel; and

a controller coupled to said color variable light source for altering the color of light generated by said variable color light source.

12. An illuminating speaker assembly according to claim 11 wherein said variable color light source comprises:

a first plurality of light-emitting diodes for emitting light of a first color; and

a second plurality of light-emitting diodes for emitting light of a second color.

13. An illuminating speaker assembly according to claim 12 wherein said variable color light source further comprises a third plurality of light-emitting diodes for emitting light of a third color.

14. An illuminating speaker assembly according to claim 13 wherein said first, second, and third colors are red, blue, and green, respectively.

15. An illuminating speaker assembly according to claim 13 wherein said controller individually varies the intensity of said first, second, and third groups of light-emitting diodes to produce resultant light of a desired color.

16. An illuminating speaker assembly according to claim 13 wherein said first, second, and third plurality of light-emitting diodes are housed in at least one light-permeable tube.

17. An illuminating speaker assembly according to claim 16 wherein said first, second, and third plurality of light-emitting diodes are housed in a plurality of light-permeable tubes.

18. A light-generating speaker assembly for use in the passenger compartment of a vehicle of the type which includes a source of potential, a source of audio electrical signals and a passenger compartment, comprising:

a flat panel speaker assembly, comprising;

a housing having a major opening therein mounted within the passenger compartment;

a light-permeable, sound-producing panel coupled to said housing and across said major opening for producing sound waves; and

a transducer mounted within said housing and having an input electrically coupled to the source of audio electrical signals and mechanically coupled to said light-permeable, sound-producing panel, for converting the audio electrical signals into acoustic energy and causing said light-permeable, sound-producing panel to vibrate;

a controller positioned within said passenger compartment and coupled to said plurality of light-emitting diodes for selectively energizing said plurality of light-emitting diodes to alter the color of light passing through said light-permeable, sound-producing panel.

19. A light-generating speaker assembly according to claim 18 wherein said plurality of light-emitting diodes include a first group for generating red light, a second group for generating green light, and a third group for generating blue light.

20. A light-generating speaker assembly according to claim 19 wherein said plurality of light-emitting diodes is housed in at least one light-permeable tube.
