ある。(Prior Art and Problems to be Solved by the Invention) Wind instruments are mainly made of wood or metal, but these have the problem that they expand and contract depending on temperature and humidity, resulting in inconsistent pitch.
本発明は温度や湿度等の環境の変化によっても寸法安定
性に優れ、音程の安定した管楽器を提供するものである
。The present invention provides a wind instrument that has excellent dimensional stability even under changes in the environment such as temperature and humidity, and has a stable pitch.
（問題点を解決するための手段）
本発明は管楽器の管体を炭素繊維強化複合材料で構成し
た管楽器に関する。(Means for Solving the Problems) The present invention relates to a wind instrument whose tube body is made of a carbon fiber reinforced composite material.
管楽器の音は管内の空気振動によって発生する。The sound of a wind instrument is generated by air vibrations within the pipe.
音の高さは空気の振動数により決定し、管体の長さが変
化すると振動数が変化して音の高さが変化し音程を狂わ
すこととなる。The pitch of the sound is determined by the frequency of the air's vibrations, and if the length of the tube changes, the frequency will change, the pitch of the sound will change, and the pitch will be thrown out of tune.
従って、音程を維持するためには環境が変化しても管体
の寸法が一定であることが望ましい。Therefore, in order to maintain the pitch, it is desirable that the dimensions of the tube remain constant even if the environment changes.
本発明者はこの目的を達成するために炭素繊維強化複合
