Technical Examples

A family of stringed musical instruments has improved tonal quality. The top plate is cylindrically curved parallel to the strings, and the back plate is cylindrically curved along an axis perpendicular to the strings. The transverse braces supporting the top plate are scalloped, leaving substantial air gaps along the glue line once the brace is attached. The back plate is supported by a substantial longitudinal brace, or spine, which runs down its center parallel to the strings. The spine contains a substantial portion of the mass of the back plate. The spine and braces are produced as a laminate, with spruce surrounding a core of ebony. These musical instruments have improved harmonic generation over common instruments, and therefore have a more complex and pleasing tone than common instruments. In addition, there is little spatial variation for the harmonics produced by these musical instruments.
