Abstract

A loudspeaker assembly for attachment to an exterior portion of a vehicle. The assembly including a loudspeaker, a base enclosure, and a grille enclosure. The loudspeaker transmits an audio output into an environment that is exterior to the vehicle. The base enclosure receives the loudspeaker and includes a first ramped surface formed on an exterior portion thereof. The grille enclosure includes an integrated loudspeaker grille to cover the loudspeaker. The grille enclosure further includes a second ramped surface positioned on an exterior portion thereof and being positioned directly adjacent to the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure. Each of the first ramped surface and the second ramped surface is non-perpendicular to the integrated loudspeaker grille.

First claim

What is claimed is:

1. A loudspeaker assembly for attachment to an exterior portion of a vehicle, the assembly comprising:
a loudspeaker for transmitting an audio output into an environment that is exterior to the vehicle;
a base enclosure to receive the loudspeaker and including a first ramped surface formed on an exterior portion thereof; and
a grille enclosure including an integrated loudspeaker grille to cover the loudspeaker, the grille enclosure further including a second ramped surface positioned on an exterior portion thereof and being positioned in abutment with the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure,
wherein each of the first ramped surface and the second ramped surface is non-perpendicular to the integrated loudspeaker grille.

2. The loudspeaker assembly of claim 1 , wherein the first ramped surface is formed at an angle that is greater than zero degrees and less than ninety degrees relative to the integrated loudspeaker grille.

3. The loudspeaker assembly of claim 2 , wherein the first ramped surface is formed at the angle of between twenty-eight degrees and sixty-three degrees relative to the integrated loudspeaker grille.

4. The loudspeaker assembly of claim 1 , wherein the second ramped surface is formed at an angle that is greater than zero degrees and less than ninety degrees relative to a first side of the grille enclosure.

5. The loudspeaker assembly of claim 4 , wherein the second ramped surface is formed at an angle that is between thirty degrees and sixty-five degrees relative to the first side of the grille enclosure.

6. The loudspeaker assembly of claim 1 , wherein first side of the grille enclosure is coupled to the exterior of the vehicle and the integrated loudspeaker grille is positioned opposite to the first side of the grille enclosure to enable the audio output to be transmitted directly into an ambient environment surrounding the vehicle.

7. The loudspeaker assembly of claim 1 , wherein the integrated loudspeaker grille includes a plurality of louvers defining a plurality of openings to enable the audio output to pass through the plurality of openings.

8. The loudspeaker assembly of claim 7 , wherein each of the plurality of louvers are angled and overlap one another to prevent fluid from contacting the loudspeaker.

9. The loudspeaker assembly of claim 1 , wherein the integrated loudspeaker grille includes a first end that is formed only on a single side of the grille enclosure.

10. The loudspeaker assembly of claim 9 , wherein the integrated loudspeaker grille includes a second end positioned opposite to the first end that is received by the base enclosure to couple the grille enclosure to the base enclosure.

11. The loudspeaker assembly of claim 1 , wherein the grille enclosure includes a living hinge positioned on a first end of the integrated loudspeaker grille to enable the integrated loudspeaker grille to rotate to and from the base enclosure.

12. The loudspeaker assembly of claim 1 , wherein the base enclosure includes a loudspeaker basket integrated therewith to receive the loudspeaker.

13. The loudspeaker assembly of claim 12 , wherein the integrated loudspeaker grille covers the loudspeaker basket when the base enclosure is coupled with the grille enclosure.

14. The loudspeaker assembly of claim 1 , wherein the integrated loudspeaker grille includes a conical shaped portion and a plurality of openings formed thereon, and wherein the conical shaped portion and the plurality of openings extend inwardly toward the loudspeaker.

15. The loudspeaker assembly of claim 14 , wherein the integrated loudspeaker grille is generally planar and defines a plurality of openings thereon to enable the audio output to pass therethrough.

16. A loudspeaker assembly for attachment to a vehicle, the assembly comprising:
a loudspeaker for transmitting an audio output from the vehicle;
a base enclosure to receive the loudspeaker and including a first ramped surface formed on an exterior portion thereof; and
a grille enclosure including an integrated loudspeaker grille to cover the loudspeaker, the grille enclosure further including a second ramped surface on an exterior portion thereof and being positioned adjacent to the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure,
wherein each of the first ramped surface and the second ramped surface extend along a non-perpendicular axis relative to the integrated loudspeaker grille, and
wherein the first ramped surface is formed at an angle that is greater than zero degrees and less than ninety degrees relative to the integrated loudspeaker grille.

17. The loudspeaker assembly of claim 16 , wherein the second ramped surface is formed at an angle that is greater than zero degrees and less than ninety degrees relative to a first side of the grille enclosure.

18. A loudspeaker assembly for attachment to a vehicle, the assembly comprising:
a loudspeaker for transmitting an audio output from the vehicle;
a base enclosure to receive the loudspeaker and including a first ramped surface formed thereon; and
a grille enclosure including an integrated loudspeaker grille to cover the loudspeaker, the grille enclosure further including a second ramped surface being positioned adjacent to the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure,
wherein each of the first ramped surface and the second ramped surface extend along a non-perpendicular axis relative to the integrated loudspeaker grille, and
wherein the grille enclosure includes a living hinge positioned on a first end of the integrated loudspeaker grille to enable the integrated loudspeaker grille to rotate to and from the base enclosure.

19. A loudspeaker assembly for attachment to a vehicle, the assembly comprising:
a loudspeaker for transmitting an audio output from the vehicle;
a base enclosure to receive the loudspeaker and including a first ramped surface formed on an exterior portion thereof; and
a grille enclosure including an integrated loudspeaker grille to cover the loudspeaker, the grille enclosure further including a second ramped surface on an exterior portion thereof and being positioned adjacent to the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure,
wherein each of the first ramped surface and the second ramped surface extend along a non-perpendicular axis relative to the integrated loudspeaker grille, and
wherein the second ramped surface is formed at an angle that is greater than zero degrees and less than ninety degrees relative to a first side of the grille enclosure.

20. A loudspeaker assembly for attachment to an exterior portion of a vehicle, the assembly comprising:
a loudspeaker for transmitting an audio output into an environment that is exterior to the vehicle;
a base enclosure to receive the loudspeaker and including a first ramped surface formed on an exterior portion thereof; and
a grille enclosure including an integrated loudspeaker grille to cover the loudspeaker, the grille enclosure further including a second ramped surface positioned on an exterior portion thereof and being positioned directly adjacent to the first ramped surface of the base enclosure when the base enclosure is coupled to the grille enclosure,
wherein each of the first ramped surface and the second ramped surface is non-perpendicular to the integrated loudspeaker grille, a
