Abstract

A speaker grille is provided including a front portion capable of sound transmission and side portions extending from the front portion. Each side portion includes an edge and a projection that extends beyond the edge, where each side portion has a substantially similar capability for sound transmission as the front portion. In one embodiment, the speaker grille comprises a perforated metal material, a fabric cloth material attached to the perforated metal material on an interior surface of the grille, and a metal cloth material attached to the fabric cloth material such that the fabric cloth material is disposed between the metal cloth material and the perforated metal material.

Claims

1. A speaker grille, comprising:

a front portion capable of sound transmission; and

side portions extending from the front portion, each side portion including an edge and a projection that extends beyond the edge in a plane of the side portion, each side portion having a substantially similar capability for sound transmission as the front portion.

2. The speaker grille of claim 1, wherein the front portion has a central face and the side portions extend from the front portion generally perpendicular to the central face.

3. The speaker grille of claim 2, wherein the front portion includes angled peripheral faces on each side of the central face, the central and peripheral faces being generally planar, and the side portions extend from the peripheral faces.

4. The speaker grille of claim 2, wherein the projection extends approximately twice the distance from the central face as does the side portion edge.

5. The speaker grille of claim 1, wherein the projection is disposed in a central region of the side portion.

6. The speaker grille of claim 1, wherein a height of the projection is approximately ⅓

of a height of the side portion.

7. The speaker grille of claim 1, wherein the projection is generally planar and rectangular.

8. The speaker grille of claim 1, wherein the grille comprises a perforated metal material.

9. The speaker grille of claim 8, wherein the grille further comprises a fabric cloth material attached to the perforated metal material on an interior surface of the grille.

10. The speaker grille of claim 9, wherein the grille further comprises a metal cloth material attached to the fabric cloth material, such that the fabric cloth material is disposed between the metal cloth material and the perforated metal material.

11. A speaker grille, comprising:

a body constructed from a perforated metal material, the body having an interior surface, a fabric cloth material attached to the perforated metal material on the interior surface, and a metal cloth material attached to the fabric cloth material such that the fabric cloth material is disposed between the metal cloth material and the perforated metal material.

12. The speaker grille of claim 11, wherein the body includes a front portion capable of sound transmission and side portions extending from the front portion, each side portion including an edge and a projection that extends beyond the edge, each side portion having a substantially similar capability for sound transmission as the front portion.

13. The speaker grille of claim 12, wherein the front portion has a central face and the side portions extend from the front portion generally perpendicular to the central face, wherein the projection extends approximately twice the distance from the central face as does the side portion edge.

14. The speaker grille of claim 12, wherein the projection is disposed in a central region of the side portion.

15. The speaker grille of claim 12, wherein a height of the projection is approximately ⅓

of a height of the side portion.

16. A speaker assembly, comprising:

an enclosure arranged to receive at least one speaker therein, the enclosure having a recess on each side thereof;

a speaker grille arranged to be mounted on the enclosure, the speaker grille including a front portion capable of sound transmission and side portions extending from the front portion, each side portion including an edge and a projection that extends beyond the edge in a plane of the side portion, the projections having a shape complementary to a shape of the enclosure recesses and are arranged to be received in the enclosure recesses, each side portion having a substantially similar capability for sound transmission as the front portion.

17. The speaker assembly of claim 16, wherein the front portion has a central face and the side portions extend from the front portion generally perpendicular to the central face, wherein the projection extends approximately twice the distance from the central face as does the side portion edge.

18. The speaker assembly of claim 16, wherein the projection is disposed in a central region of the side portion.

19. The speaker assembly of claim 16, wherein a height of the projection is approximately ⅓

of a height of the side portion.

20. The speaker assembly of claim 16, wherein the speaker grille comprises a perforated metal material, a fabric cloth material attached to the perforated metal material on an interior surface of the grille, and a metal cloth material attached to the fabric cloth material such that the fabric cloth material is disposed between the metal cloth material and the perforated metal material.
