Abstract

A soundboard for a musical instrument is disclosed the soundboard having at least one layer of material. In some embodiments the material comprising carbon fiber, fibrous laminate material, resin or a plastic matrix and combinations thereof. At least one bracing structure is engaged to the at least one layer of material. The at least one bracing structure comprising at least one layer of honeycomb or shaped core and at least one sheet of material bonded to the honeycomb or shaped core.

First claim

The invention claimed is:

1. A device comprising:
a soundboard comprising a first layer of material comprising a first area; and
a reinforcing material attached to the first layer of material, the reinforcing material comprising a first laminate layer, a shaped core layer and a second laminate layer, the shaped core layer comprising a plurality of cells, the reinforcing material comprising a second area, the second area less than the first area;
the reinforcing material comprising a first layer of reinforcing material, the device further comprising a second layer of reinforcing material comprising a third laminate layer, a second shaped core layer and a fourth laminate layer, the second layer of reinforcing material comprising a third area, the third area less than the second area;
the third laminate layer contacting the second laminate layer.

2. The device of claim 1 , the first laminate layer contacting the first layer of material.

3. The device of claim 1 , wherein the cells comprise hexagons.

4. The device of claim 1 , the reinforcing material comprising a plurality of tapered point portions.

5. The device of claim 1 , the reinforcing material symmetrical across a bisecting medial reference line.

6. The device of claim 5 , wherein the first layer of material is asymmetrical across the bisecting medial reference line.

7. The device of claim 1 , a perimeter of the reinforcing material comprising a plurality of peaks and a plurality of valleys.

8. The device of claim 7 , the reinforcing material comprising at least six peaks.

9. The device of claim 7 , wherein a perimeter of the reinforcing material is longer than a perimeter of the first layer of material.

10. The device of claim 1 , comprising a sound box comprising a side wall, the first layer of material attached to the sidewall, the reinforcing material not contacting the side wall.

11. The device of claim 1 , the first laminate layer and the second laminate layer comprising carbon fiber.

12. The device of claim 11 , the first layer of material comprising carbon fiber.

13. The device of claim 1 , the first laminate layer oriented parallel to the second laminate layer.
