Problems solved by technology

However, when a solid wood block is cut to manufacture a panel and a back panel, there is a problem that time and labor are required due to an extremely large cutting process, and the material yield is very low at about 10%.
However, when the laminated wood is cut, the cross-section of the laminate is exposed to the surface, and a good appearance cannot be obtained

[0029] In this embodiment, a front plate of a violin is described as an example of a plate for a stringed instrument according to the present invention. Figure 1A is a sectional view along the width direction of the panel of the violin according to the first embodiment of the present invention. Figure 1B is showing Figure 1A Floor plan of panel shown. Figure 1A is along Figure 1B A cross-sectional view taken along the line A-A'.

[0030] like Figure 1A As shown, the panel 10 of the violin includes a laminated board 11 having an arcuate shape, and the laminated board 11 is bent to face the front surface 11a ( Figure 1A top surface) is curved on one side.

[0031] The thickness of the laminated board 11 is partially different, such as Figure 1A shown. Regarding the thickness of the laminated board 11 , the thickness of the peripheral edge 13 is the thickest, the thickness of the central portion 12 is the second thickest, and the thin portion 14 is formed between the cen...

[0070] In this embodiment, a back plate of a violin will be described as an example of a plate material for a stringed instrument according to the present invention.

[0071] According to the backboard of the violin of this embodiment and according to Figure 1A The panel 10 of the first embodiment shown is different in that: taking into account the function of the back panel, the plane shape of the veneer forming the core panel is determined according to the thickness distribution; and preferably, used as a front surface panel, a rear surface panel And the material of the core board is maple.

[0072] In the back panel according to this embodiment, it is more preferable that the front surface panel, the rear surface panel and the core panel are all made of maple wood. By allowing all the veneers to be made of maple, a better function as a backboard can be obtained and the sound quality of a violin using this backboard can be further improved. Furthermore, in the back panel a...

Abstract

A board for a stringed instrument which forms a front plate or a back plate of a stringed instrument, includes: a laminated plate (11) 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.

Description

technical field [0001] The present invention relates to a panel for a stringed instrument, a method of manufacturing a panel for a stringed instrument and a stringed instrument. Background technique [0002] The top and back panels of the violin have partially different thicknesses in order to obtain satisfactory acoustic characteristics, and have a unique camber shape slightly curved to be convex toward its front surface side or rear surface side. Panels and back panels used in violas, cellos, and double basses, which are musical instruments belonging to the violin family, also have arcuate shapes with partially different thicknesses, as is the case in violins. [0003] In the prior art, during the manufacture of the top and back panels of violin family instruments, solid wood blocks are cut or carved to be shaped into curved shapes with partially different thicknesses. However, when a solid wood block is cut to manufacture a face plate and a back plate, there is a problem...
