ABSTRACT:
A soundboard assembly for use in a piano, harpsicord or similar stringed musical instrument comprises a thin, laminated soundboard consisting of a center sheet of wood and two outer layers of composite material. The center wooden sheet has a substantially unidirectional grain and the two outer layers of composite material are made of unidirectional carbon fibers embedded in a resin matrix. A plurality of ribs, which may also be made as laminations of wood and layers of composite material, are secured to one face of the soundboard, and the ribs, grain of the wood, and direction of the carbon fibers are so related to one another and to the associated bridge as to produce a desirable reaction from the soundboard in response to string vibrations transmitted to it through the bridge.
