A manufacturing method for a board for a stringed instrument that is used as a top plate or a back plate of an acoustic stringed instrument such as a violin, where the board has a purfling, includes forming, for instance, a groove with a depth that is 20% or more and less than 60% of a thickness of the board for a stringed instrument, filling the groove with a resin in which, for instance, colored particles having a diameter of 3 &#x3bc;m or more and less than 70 &#x3bc;m are dispersed and which has a degree of elongation of 20% or more, removing the resin that has flowed out of the groove, and curing the resin.

Board for stringed instrument, acoustic stringed instrument, and method of manufacturing board for stringed instrument

An acoustic string instrument includes a top plate, a back plate, and a body disposed between the top plate and the back plate. The body has a plurality of first positioning portions. At least one of the top plate or the back plate, or both has a plurality of second positioning portions. The first positioning portions are fixed to the second positioning portions corresponding to the first positioning portions.

Acoustic string instrument, and methods for manufacturing and repairing same

An acoustic material is provided which includes a plurality of wood veneers laminated via an adhesive, in which the veneer is impregnated with the adhesive, and the adjacent veneers are substantially in contact with one another. The adjacent veneers are impregnated with the adhesive in an amount of preferably no less than 1 g/mand no greater than 50 g/mper unit area in and around a boundary region of the adjacent veneers. The adhesive may be a water-soluble adhesive or a water-based emulsion adhesive. The veneer may be a rotary veneer, a sawn veneer or a sliced veneer. A musical instrument is further provided which includes a sound board, in which the acoustic material is used as the sound board.

Acoustic material and musical instrument

A board for a stringed instrument which forms a front plate or a back plate of a stringed instrument, includes: a laminated plate that is obtained by laminating a plurality of veneers having a uniform thickness by an adhesive, at least one of the veneers having a different planar shape than the other veneers, in which the laminated plate is curved to be convex toward one surface side and has a thin portion and a thick portion.

Board for stringed instrument, method of manufacturing board for stringed instrument, and stringed instrument

A board for a stringed instrument which forms a front plate or a back plate of a stringed instrument, includes: a veneer that includes a concave portion for partially reducing the thickness of the veneer, in which the veneer is curved to be convex toward one surface side. In this board for a stringed instrument, fiber of the veneer may extend along the curved shape of the veneer.
