- Such chimes are often used for performances of orchestral music, etc., but they are often used in the form of orchestral music in the form of a church bell. Therefore, it is often desired that the chime sound, that is, the sound generated by the chime sound tube, be a solid sound like a church bell. However, it cannot be said that the sound pipes that have been used in the past are sufficiently heavy. This problem is common not only to sound tubes used for chimes, but also to sound tubes that are tubular sound generators in general.

- the weight of the sound tube cap used for general chimes is, for example, 144 g or 193 g.
- Increasing the weight of the cap 12 changes the vibration mode of the sound tube 10 and changes the strength, pitch, or attenuation characteristics of various harmonics, thereby changing the quality of the sound generated by the sound tube 10. To do. Since the intensity of the secondary overtone increases as the weight of the cap 12 increases, the sound is felt thicker. The greater the weight of the cap 12, the lower the pitch of the third harmonic when tuning using the fourth harmonic. The greater the weight of the cap 12, the greater the deviation in the integer ratio of each overtone. Specifically, by increasing the weight of the cap 12, the sound of the sound tube 10 (sound elongation) is improved and the sound generated by the sound tube 10 becomes heavy.
- the effect of improving the reverberation is brought about by increasing the intensity of the primary and secondary harmonics among the harmonics included in the sound generated by the sound tube 10. Moreover, the effect that the sound becomes profound is brought about by the following two phenomena.
- the first phenomenon is that the sound tube 10 is less likely to vibrate in a vibration mode that generates higher harmonics, and the fifth harmonics are attenuated relatively faster than the fourth harmonics. It is a phenomenon that will stand out.
- the second phenomenon is a phenomenon in which the pitches of the first, second, and third harmonics are lowered and the pitches of the fifth and sixth harmonics are increased. In this way, by increasing the weight of the cap 12 constituting the sound tube 10, the sound of the sound tube 10 can be improved and the sound generated by the sound tube 10 can be made heavy.

Abstract
Description
本願は、2016年3月22日に日本国に出願された特願2016-057308号に基づいて優先権を主張し、その内容をここに援用する。
図1は、本発明の一実施形態に係るチャイム1(「チューブラーベル」とも呼ばれる)の全体構成を示す斜視図である。チャイム1は、複数の音管10(「サウンドコラム」とも呼ばれる)と、音管10を吊り下げるためのフレーム20とを備えている。フレーム20は、脚部21と、脚部21の左右両端部から鉛直上方に立ち上がる2本の支柱22と、2本の支柱22の上端を渡すように形成されたハンガー30とを有している。ここで左右あるいは上方とは、演奏者側からチャイム1を見た際の方向である。以下においても、特に記載がない限り、上下左右の各方向を、演奏者側からチャイム1を見た際の方向として規定する。以下において、前後方向は、チャイム1を基準として演奏者側の方向を前とし、演奏者側の反対方向を後として規定する。
図2は、音管10の断面図であり、その中心軸A(図2における一点鎖線)を通る平面で音管10を切断した断面を示している。音管10は、図1に示すように上下方向に長く延びている。図示の便宜上、図2は、音管10の上端部のみを示している。図2に示すように、音管10は、管体11と、キャップ12とを有している。管体11とキャップ12とは、それぞれ、真鍮(黄銅)や洋白等の金属で形成された部材であり、必要に応じてラッカー塗装、あるいは、クロムめっき等のめっきが施される。真鍮の比重は、約8.5である。洋白の比重は、約8.7~8.8である。管体11とキャップ12の材料は、銅合金であってもよい。銅合金の比重は、約8~9である。銅合金は、青銅やリン青銅であってもよい。キャップ12の材料は、炭素鋼であってもよい。炭素鋼の比重は、約7.9~8.0である。キャップ12の材料として炭素鋼を用いることにより、より安価に音管10を製造することができる。
一般的に、チャイム1(図1)に使用される音管10では、打撃により発生する種々の倍音の強度、音高、あるいは減衰特性を変化させ、音管10で発生する音の質を変化させることにより、調音が行われる。そして、打撃で発生する種々の倍音のうち、4次の倍音を基音として扱い、4次の倍音を用いて調律が行われる。本実施形態において、キャップ12は、一般的なチャイムに使用される音管のキャップよりも、重量が大きく設定されている。一般的なチャイムに使用される音管のキャップの重量は、例えば、144gや193gである。キャップ12の重量を大きくすることにより、音管10の振動モードが変化して、種々の倍音の強度、音高あるいは減衰特性等が変化することで、音管10の発生する音の質が変化する。キャップ12の重量が大きくなるほど、2次の倍音の強度が大きくなるため、音が太く感じられる。キャップ12の重量が大きくなるほど、4次の倍音を用いて調律を行った場合に3次の倍音のピッチが下がる。キャップ12の重量が大きくなるほど、各倍音の整数比のずれがより大きくなる。具体的には、キャップ12の重量を大きくすることにより、音管10の響き(音の伸び)が良くなるとともに、音管10が発生する音が重厚になる。響きが良くなる効果は、音管10が発生する音に含まれる倍音のうち、1次および2次の倍音の強度が上昇することによりもたらされる。また、音が重厚になる効果は、以下の2つの現象によりもたらされる。第1の現象は、高次の倍音を発生させる振動モードで音管10が振動しにくくなり、5次の倍音が4次の倍音よりも相対的に減衰が早くなるため、4次の倍音が際立つようになる現象である。第2の現象は、1次、2次および3次の倍音の音高が低くなり、5次および6次の倍音の音高が高くなる現象である。このように、音管10を構成するキャップ12の重量を大きくすることにより、音管10の響きを良くするとともに、音管10が発生する音を重厚なものにすることができる。
本発明は上記実施形態に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能であり、例えば、次のような変形も可能である。
上記実施形態においては、単一の音管10に関して、キャップ12の重量や各部の寸法の好適な範囲を規定している。音高が異なる複数の音管10を使用する際に、各音管10の音高に応じてキャップ12の重量を調整することも可能である。一般的に、音高の異なる複数の音管10を有する楽器(すなわち、チャイム1)は、低音側において発生する音がより重厚で、かつ、高音側において発生する音が過度に重厚でない、全体としてバランスのとれた音を発生することが求められる。そこで、音高が低い音管10が発生する音を十分に重厚にするとともに、音高が高い音管10が発生する音を過度に重厚なものとしないように、音高が低い音管10のキャップ12を、音高が高い音管10のキャップ12よりも重くするのが好ましい。
上記実施形態においては、チャイムとして、前方と後方との2列に音管10が配列されたチャイム1を示している。本発明の実施形態は、音管10が一列に配列されたチャイム、あるいは、単一の音管10のみを有するチャイム等にも適用することができる。また、本発明の実施形態は、音管10を有する楽器であるチャイムの他、チャイムで使用可能なように個別に提供される音管10そのものにも適用することができる。さらに、本発明の実施形態は、打撃により発音するチャイム1用の音管10に限らず、管状の発音体(音管)であれば、摩擦等の他の方法により発音する種々の音管にも適用することができる。
キャップ12の形状は、図2に示す形状に限定されない。図8は、変形例に係るキャップ12Aを示す。キャップ12Aは、キャップ12と比較して、組付部121Aの形状が相違する。それ以外の点においては、キャップ12Aの構成は、キャップ12と同じである。図8に示すように、組付部121Aの中心穴129の径は、大径部122からは離れるにつれて徐々に大きくなっている。大径部122の中心穴129の径も、大径部122の外部に露出している端から離れるにつれて徐々に大きくなっていてもよい。すなわち、中心穴129の径の少なくとも一部は、大径部122の外部に露出している端から離れるにつれて徐々に大きくなっていてもよい。組付部121Aの長さは、キャップ12を管体11に組み付けた状態で貫通穴119を塞がないように設定されている。よって、組付部121Aの長さは、管体11の一端から貫通穴119までの長さよりも短い。
