Abstract

A substrate injection molded to a surface of metal, wood, a wood-based product, or leather to form a composite, such that the composite has an acoustical region and a non-acoustical region, and the surface extends continuously from the acoustical region to the non-acoustical region is described.

Claims

1. An apparatus comprising

a substrate injection molded to a surface of metal, wood, a wood-based product, or leather to form a composite, the composite having an acoustical region and a non-acoustical region;

the surface extending continuously from the acoustical region to the non-acoustical region.

2. The apparatus of claim 1 in which the substrate is substantially coextensive with the surface.

3. The apparatus of claim 1 in which the surface is on a sheet of material.

4. The apparatus of claim 1, wherein the non-acoustical region comprises more than half of an area of the surface.

5. The apparatus of claim 1, further comprising an audio device to which the composite is mounted.

6. The apparatus of claim 1, further comprising an automobile door to which the composite is mounted.

7. The apparatus of claim 1 in which the acoustical region bears holes.

8. The apparatus of claim 1 further comprising a loudspeaker in a vicinity of the acoustical region.

9. An apparatus comprising

a loudspeaker;

a screen in the vicinity of the loudspeaker, the screen having holes and comprising a substrate injection molded onto a surface of metal, wood, a wood-based product, or leather.

10. The apparatus of claim 9, wherein the surface comprises leather.

11. The apparatus of claim 9, wherein the loudspeaker has a diameter and at least one dimension of at least one of the holes spans the diameter of the loudspeaker.

12. The apparatus of claim 9, wherein the loudspeaker has a circumference and a radius of curvature, and at least one of the holes has a radius of curvature equal to the radius of curvature of the circumference.

13. The apparatus of claim 9, wherein the holes are generally rectangular.

14. The apparatus of claim 10, wherein the holes are arcuate.

15. The apparatus of claim 9, wherein the holes are generally circular.

16. A method comprising

in an article having a substrate molded onto a surface of metal, wood, a wood-based product, or leather, forming holes in the surface after the substrate has been molded onto the surface.

17. The method of claim 16, wherein forming holes comprises laser-cutting the surface.

18. The method of claim 16 wherein forming holes comprises applying water jets to the surface.

19. The method of claim 16 wherein forming holes comprises punching the surface.
