Abstract

An integrated speaker and lamp assembly includes a speaker diaphragm and a light source directing light through the speaker diaphragm. A related method of integrating a speaker and a lamp is also disclosed.

Claims

1. An integrated speaker and lamp assembly, comprising:

a speaker diaphragm;

a light source of the lamp assembly directing light through said speaker diaphragm;

an integrated switch to control said light source, wherein said integrated switch includes a sensor layer bonded to a first face of said speaker diaphragm;

a printed circuit board wherein said light source is carried on said printed circuit board; and

an actuator carried on said printed circuit board for driving said speaker diaphragm.

2. The integrated speaker and lamp assembly of claim 1, wherein said speaker diaphragm is transparent.

3. The integrated speaker and lamp assembly of claim 2, including a photoluminescent layer on a second face of said speaker diaphragm.

6. The integrated speaker and lamp assembly of claim 3, wherein said light source is a blue LED and said photoluminescent layer is a rylene dye.

11. A method of integrating a speaker and a lamp including a light source, comprising:

providing a photoluminescent layer on a first face of a speaker diaphragm;

bonding a sensor layer to a second face of said speaker diaphragm;

configuring said sensor layer to switch the light source between an activated state and a deactivated state in response to touching said speaker diaphragm; and

directing light from said light source through said speaker diaphragm.

15. The method of claim 11, including using a transparent speaker diaphragm.

16. The method of claim 15, including using a blue LED for said light source.

17. The method of claim 16, including using a rylene dye for said photoluminescent layer and directing light through said transparent speaker diaphragm onto said rylene dye.

18. The method of claim 17, including mounting said speaker diaphragm on a trim panel of a motor vehicle.

19. The method of claim 17, including mounting said speaker diaphragm on a door panel of a motor vehicle.

20. The method of claim 17, including mounting said speaker diaphragm on a center stack or console of a motor vehicle.
