Manufacturing method and manufacturing system of piano soundboard

Abstract

The invention relates to the manufacturing field of pianos, and specifically relates to a manufacturing method and a manufacturing system of a piano soundboard. The manufacturing method of the piano soundboard comprises the following steps of: manufacturing a core board, wherein the core board is rectangular, drying core board wood, cutting the core board wood into core board battens according to predetermined width, connecting a plurality of core board battens in by finger joint, thickening the connected core board battens, bonding and splicing the side edges of the plurality of thickened core board battens to obtain a core board manufacturing panel, chopping panel wood into veneers according to the predetermined thickness, drying the veneers, bonding and splicing the side edges of a plurality of veneers according to the condition that an angle between the texture direction and the long edges of the soundboard is 40-50 DEG to obtain panels, and respectively bonding two panels with the upper surface of the core board and the lower surface of the core board to obtain the soundboard. The manufacturing method and the manufacturing system of the piano soundboard, provided by the invention, are capable of solving the problem that the soundboard is capable of cracking since the external moisture change of the soundboard has the possibility of causing air shrinkage and wet expansion.

Description

technical field [0001] The invention relates to the field of piano manufacturing, in particular to a method for manufacturing a piano soundboard and a manufacturing system for a piano soundboard. Background technique [0002] Piano, violin, and classical guitar are known as the world's three major musical instruments. The piano includes a sounding mechanism, a string action mechanism, a pedal mechanism and a shell, wherein the sounding mechanism includes strings and a soundboard. In the piano, the soundboard, the string frame, the back frame and other string tension systems jointly carry the huge tension from the strings. When the strings are excited to vibrate, the soundboard is shaken through the conduction of the string codes attached to the soundboard. The soundboard not only responds to the vibrations from the strings, but also resonates, enhancing the volume. The soundboard is like a filter, which can modify the timbre of the piano. When judging the sound effect of ...

Problems solved by technology

[0004] However, because the existing anisotropic solid wood soundboard is made of a whole piece of material wood, when the solid wood soundboard is affected by external moisture, for example, the solid wood soundboard is immersed in external moisture, and the solid wood soundboard is damp and causes hygroscopic expansion. When the ambient humidity around the soundboard decreases, the moisture in the solid wood soundboard will evaporate, causing the wood of the solid wood soundboard to shrink and crack, and the cracked soundboard will not be able to vibrate well, resulting in the failure of the entire piano
