A grand piano soundboard

Abstract

A grand piano resonant plate, comprising a back frame, a peg board is glued and connected to the front upper part of the back frame, the sound board is adjacent to the peg board and fixed above the front of the back frame, the string code is glued to the front of the sound board, and the top of the peg board is fixed The iron frame is installed, the string nail and the peg are installed in the hole of the iron frame, one end of the string row is wound on the peg, and the other end is hooked on the string nail. The sound board includes a top plate and a back frame, wherein, The top plate is tightly spliced ​​by a plurality of laths that are thick at one end and thin at the other end. Ribs are glued longitudinally on the lower surface of the top plate, and the four sides of the top plate are tightly glued to the back frame. The hanging nail includes a fixing part and a hanging part, wherein the fixing part is provided with a locking part, and the hanging nail is provided with a groove. The present invention provides a grand piano resonant plate, through the improvement of the sound board and string nails of the resonant plate, on the one hand, the sound quality, timbre, and volume are all improved, and on the other hand, it overcomes the loosening of the fixed parts due to long-term vibration. bad influence.

Description

technical field [0001] The invention relates to the technical field of pianos, in particular to a grand piano soundboard. Background technique [0002] The standard range of a modern grand piano is 88 tones, which is 7 according to the usual saying. 1 / 3 Group, the standard range of an upright piano includes 85 tones, that is, 7 groups, there are also 7 1 / 3 The upright piano of group, baby grand piano sometimes also has 7 groups of ranges, and upright piano also has 6 groups in order to reduce the volume sometimes. 1 / 2 Smaller groups or ranges (children's instruments), this narrowing of the range can reduce either the bass or the treble, or both. [0003] In the structure of the piano, the soundboard is also called the heart of the piano, and it is the key to the sound of the whole piano. The resonating plate is mainly composed of soundboard, string code, iron frame, string column and back frame, etc. By plucking the string column, the string column and the soundboard reso...

AI Technical Summary

Problems solved by technology

The quality of the sound of the piano is related to many factors, such as the material selection and layout of the soundboard during the manufacturing process, and whether the soundboard and the string code are glued tightly; during use, due to long-term vibration and stress, fastening The parts are easily damaged and loose, which will cause noise, damage the tone, and deteriorate the working environment of the resonator, shortening the service life of the piano
