Abstract

An instrument cluster assembly is provided and includes a case assembly having a visor attached to a front side of the case assembly, the visor having at least one sound hole. The instrument cluster assembly also includes a dial sheet having at least one indicator. The instrument cluster assembly also includes a lens mounted to the visor such that the at least one indicator of the dial sheet is viewable through the lens. The instrument cluster assembly also includes a speaker that generates sound waves and a sound tube that directs the sound waves from the speaker to the at least one sound hole of the visor such that the sound waves generated by the speaker travel through the sound tube and exit the at least one sound hole of the visor without traveling through the dial sheet and the lens.

First claim

What is claimed is:

1. An instrument cluster assembly comprising:
a case assembly having a visor attached to a front side of the case assembly, the visor having at least one sound hole;
a dial sheet mounted within the case assembly, the dial sheet having at least one indicator;
a lens mounted to the visor such that the at least one indicator of the dial sheet is viewable through the lens;
a speaker mounted within the instrument cluster assembly that generates sound waves;
a sound tube within the instrument cluster assembly that directs the sound waves from the speaker to the at least one sound hole of the visor such that sound waves generated by the speaker travel through the sound tube and exit the at least one sound hole of the visor without traveling through the dial sheet and the lens; and
a printed circuit board mounted within the instrument cluster assembly, the printed circuit board including electronics that control a graphical display of the instrument cluster assembly;
wherein the printed circuit board includes an aperture that is aligned with the sound tube and aligned with the speaker.

2. The instrument cluster assembly of claim 1 , wherein the sound tube is formed by the case assembly.

3. The instrument cluster assembly of claim 1 , wherein the speaker is mounted to the printed circuit board.

4. The instrument cluster assembly of claim 1 , wherein the speaker is mounted to the case assembly.

5. The instrument cluster assembly of claim 1 , further comprising:
a rear cover attached to a rear side of the case assembly, the rear cover including a resonance chamber that amplifies the sound waves generated by the speaker.

6. The instrument cluster assembly of claim 1 , wherein the at least one sound hole of the visor is hidden from view when by a bezel of an instrument panel when the instrument cluster assembly is installed in the instrument panel.

7. An instrument panel comprising:
a bezel; and
the instrument cluster assembly of claim 1 ;
wherein the bezel of the instrument panel overlaps the lens of the instrument cluster assembly such that the at least one sound hole of the visor is hidden from view by the bezel and the sound waves exiting the at least one sound hole travel through the bezel.

8. An instrument cluster assembly comprising:
a case assembly having a visor attached to a front side of the case assembly, the visor having at least one sound hole;
a dial sheet mounted within the case assembly, the dial sheet having at least one indicator;
a lens mounted to the visor such that the at least one indicator of the dial sheet is viewable through the lens;
a speaker mounted within the instrument cluster assembly that generates sound waves;
a sound tube within the instrument cluster assembly that directs the sound waves from the speaker to the at least one sound hole of the visor such that sound waves generated by the speaker travel through the sound tube and exit the at least one sound hole of the visor without traveling through the dial sheet and the lens;
wherein the at least one sound hole of the visor is hidden from view by a bezel of an instrument panel when the instrument cluster assembly is installed in the instrument panel.
