Abstract

An example vehicle instrument panel includes a speaker for producing alert and warning sounds. A membrane prevents water from intruding into the speaker assembly and instrument panel. The membrane is spaced apart from the speaker and over an open end of the speaker housing. Sound energy from the speaker travels through an open space against the membrane. The membrane possesses acoustic properties to receive and pass on the sound energy.

Claims (25)

1. A speaker assembly for a vehicle instrument panel comprising:

an instrument panel including a substantially vertical front facing surface;

a housing including an open end, the housing within the instrument panel such that the open end faces outwardly from the vertical front facing surface of the instrument panel;

a speaker mounted within the housing for producing sound energy; and

a membrane resistant to water covering the open end of the housing for communicating sound energy from the speaker outward from the housing.

2. The speaker assembly as recited in claim 1 , wherein the membrane comprises water proof material.

3. The speaker assembly as recited in claim 2 , wherein the membrane amplifies sound energy generated by the speaker.

4. The speaker assembly as recited in claim 1 , wherein the speaker is mounted to a printed circuit board disposed within the housing.

5. The speaker assembly as recited in claim 1 , wherein the open end of the housing is directed outwardly from the vehicle instrument panel.

6. The speaker assembly as recited in claim 1 , wherein the housing comprises a cylinder having a round open end and a bezel for installation in the vehicle instrument panel.

7. An instrument panel assembly comprising:

an instrument panel defining a substantially front facing vertical surface;

at least one gauge for displaying a vehicle operating parameter mounted within the instrument panel; and

a speaker assembly mounted within the instrument panel and directed outward from the instrument panel parallel with the substantially vertical surface, the speaker assembly including a speaker for generating sound energy and a membrane covering the speaker and preventing water from contacting the speaker, the membrane communicating sound energy from the speaker outwardly from the instrument panel.

8. The instrument panel assembly as recited in claim 7 , including a housing supported within the instrument panel and including an open end, wherein the speaker is disposed within the housing and the membrane is mounted over the open end.

9. The instrument panel assembly as recited in claim 8 , including a printed circuit board to which the speaker is attached.

10. The instrument panel assembly as recited in claim 8 , including an amplifier for generating signals received by the speaker for generating sound energy.

11. The instrument panel assembly as recited in claim 7 , including a bezel mounted to the housing and the instrument panel.

12. A dashboard assembly comprising:

a dashboard defining a top substantially horizontal surface;

an instrument panel disposed below the dashboard and transverse to the top horizontal surface, the instrument panel including at least one gauge for providing a visual indication of a vehicle operating parameter; and

a speaker assembly facing outwardly from the instrument panel in a direction common with the at least one gauge for generating noises to alert a vehicle operator of a vehicle condition, wherein the speaker includes a membrane covering the open end of the speaker for preventing moisture from contacting the speaker assembly.

13. The assembly as recited in claim 12 , wherein the speaker assembly comprises a housing defining an open end, where the open end faces outward from the instrument panel toward a vehicle operator.

14. The assembly as recited in claim 12 , wherein the speaker assembly comprises a speaker supported within the housing and spaced apart from the membrane, wherein the speaker generates noise energy received and amplified by the membrane.

15. The assembly as recited in claim 12 , wherein the speaker assembly is visibly mounted within the instrument panel.
