以下、この発明の金管楽器用消音器の実施の形態について説明するが、この発明の実施の形態は、発明の最も好ましい形態を示すものであり、この発明はこれに限定されない。
［実施の形態１］
以下、この発明の実施の形態に係る金管楽器用消音器を図１及び図２に従って詳細に説明する。図１はこの発明の金管楽器用消音器が装着されるトランペットの概略斜視図、図２はトランペットに装着した状態の消音器の断面図である。
Hereinafter, embodiments of the silencer for brass instruments according to the present invention will be described. However, the embodiments of the present invention show the most preferable embodiments of the present invention, and the present invention is not limited thereto.
[Embodiment 1]
A brass silencer according to an embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 is a schematic perspective view of a trumpet to which a brass silencer according to the present invention is mounted, and FIG. 2 is a cross-sectional view of the silencer in a state where the trumpet is mounted.
符号１はトランペット用消音器を示し、この消音器１はトランペット１００のベル１０１に着脱自在に装着される。トランペット１００には、マウスピース１０２が取り付けられ、このマウスピース１０２はトランペット１００の先端のベル１０１から出る音を発生する入口であり、音程や音色等に影響する。消音器１は、胴部３と底部５とからなる消音器本体７を備えている。 Reference numeral 1 denotes a trumpet silencer. The silencer 1 is detachably attached to the bell 101 of the trumpet 100. A mouthpiece 102 is attached to the trumpet 100, and the mouthpiece 102 is an entrance for generating a sound coming out from the bell 101 at the tip of the trumpet 100, and affects the pitch, tone color, and the like. The silencer 1 includes a silencer main body 7 including a body portion 3 and a bottom portion 5.
胴部３は、アルミニウムで成形されているが、合成樹脂で成形されてもよい。この胴部３は、図２に示すように、直線部３ａと傾斜部３ｂとに分かれている。直線部３ａは消音器本体７の軸線方向（Ｂ−Ｃ方向）と平行になっており、胴部３の上端部としての大径側端部３ｃを含む直線部３ａ側が消音器本体７の最大外径部及び最大内径部７ａをなしている。傾斜部３ｂは直線部３ａと連続し、直線部３ａの一端部からベル１０１の内周面の形状に沿うように比較的滑らかに傾斜して絞られており、先細りしているので小径側端部３ｅ側が消音器本体７の最小外径部及び最小内径部７ｂをなしている。この小径側端部３ｅ側で内側に折り返し、折り返し部３ｆからさらに内側に延びる軸線が消音器本体１１の軸線方向（Ｂ−Ｃ方向）と一致するよう延びた調整筒３ｇが形成され、呼気を内部空間２１に導入する呼気導入開口部８０としている。調整筒３ｇは先細りであり、調整筒３ｇの先端部の内径Ｄ１より折り返し部３ｆの内径Ｄ２が大きく設定され、折り返し部３ｆの基部から調整筒３ｇの先端部までの長さＬ１を所定長さに設定している。 Although the trunk | drum 3 is shape | molded with aluminum, you may shape | mold with a synthetic resin. As shown in FIG. 2, the body portion 3 is divided into a straight portion 3a and an inclined portion 3b. The straight line portion 3 a is parallel to the axial direction (BC direction) of the silencer body 7, and the straight line portion 3 a side including the large-diameter side end portion 3 c as the upper end portion of the body portion 3 is the maximum of the silencer body 7. An outer diameter portion and a maximum inner diameter portion 7a are formed. The inclined portion 3b is continuous with the straight portion 3a, and is narrowed and squeezed relatively smoothly so as to follow the shape of the inner peripheral surface of the bell 101 from one end portion of the straight portion 3a. The part 3e side forms the minimum outer diameter part and the minimum inner diameter part 7b of the silencer body 7. An adjustment cylinder 3g is formed which is folded inwardly on the small diameter side end 3e side and extends so that the axis extending further inward from the folded portion 3f coincides with the axial direction (BC direction) of the silencer body 11. The breath introduction opening 80 is introduced into the internal space 21. The adjustment cylinder 3g is tapered, and the inner diameter D2 of the folded portion 3f is set larger than the inner diameter D1 of the distal end portion of the adjustment cylinder 3g, and a length L1 from the base portion of the folded portion 3f to the distal end portion of the adjustment cylinder 3g is a predetermined length. Is set.
このように、消音器本体７の内部空間２１は軸線方向（Ｂ−Ｃ方向）に沿ってＢ方向に進むほど拡径化し、折り返し部３ｆからさらに内側に延びる調整筒３ｇを形成することで、消音器１をベル１０１に装着しても鳴りムラが無く、しかも音程の良い音が得られ、その結果として安定した吹奏感も得られる。 Thus, the inner space 21 of the silencer body 7 is enlarged in diameter as it proceeds in the B direction along the axial direction (BC direction), and the adjustment cylinder 3g extending further inward from the folded portion 3f is formed. Even if the muffler 1 is attached to the bell 101, there is no unevenness in sound and a sound having a good pitch can be obtained. As a result, a stable feeling of wind can be obtained.
調整筒３ｇの寸法は対応する楽器の種類によって異なった設定が必要となるが、本実施例で装着されるトランペット１００は変ロ調のトランペットなので、調整筒３ｇの内径はφ１５ｍｍ、外径はφ１７ｍｍ、長さは１５ｍｍ程度である。調整筒３ｇが備えられたことにより、トランペット１００のピッチを若干下げることができ、特に低音域の音程バランスを改善できる。 Although the dimensions of the adjustment cylinder 3g need to be set differently depending on the type of the corresponding instrument, the trumpet 100 to be mounted in this embodiment is a trumpet having a strange adjustment, so the inner diameter of the adjustment cylinder 3g is φ15 mm and the outer diameter is φ17 mm. The length is about 15 mm. By providing the adjusting cylinder 3g, the pitch of the trumpet 100 can be slightly lowered, and in particular, the pitch balance in the low range can be improved.
ベル１０１に消音器１を装着した場合には、傾斜部１１の外周面は嵌合部３ｈに柔軟取付部材９０を介してベル１０１の内周面と嵌合する。柔軟取付部材９０としては、変形して柔軟性を有するものであればよく、ゴム製部材、樹脂性部材、あるいは布製部材などであり、柔軟取付部材９０は嵌合部３ｈに接着剤により貼り付けられており、この材料の特性により良好にベル１０１の内周面に密着して嵌合し固定され、呼気が漏れないようになっている。 When the silencer 1 is mounted on the bell 101, the outer peripheral surface of the inclined portion 11 is fitted to the inner peripheral surface of the bell 101 via the flexible attachment member 90 in the fitting portion 3h. The flexible mounting member 90 only needs to be deformed and flexible, and is a rubber member, a resin member, or a cloth member. The flexible mounting member 90 is attached to the fitting portion 3h with an adhesive. Due to the characteristics of this material, the inner wall of the bell 101 is satisfactorily closely fitted and fixed so that exhalation does not leak.
底部５は、アルミニウムで成形されているが、合成樹脂で成形されてもよく、椀状に成形されている。底部５は開口端５ａを胴部３の大径側端部３ｃ側のフランジ３ｉに嵌合し、底部５には軸線方向（Ｂ−Ｃ方向）と直交する方向（Ｄ−Ｅ方向）に最大内径部５ｅがあり、この最大内径部５ｅがベル１０１の端面１０１ａに位置している。底部５と胴部３の直線部３ａとの嵌合部は消音器１、特に消音器本体７の内部空間２１にある空気がそこから漏れないように密閉されている。これにより、鳴りむらの無い安定した音が全音域で演奏可能となる。 The bottom portion 5 is molded from aluminum, but may be molded from a synthetic resin, and is shaped like a bowl. The bottom portion 5 has an open end 5a fitted into a flange 3i on the large-diameter side end portion 3c side of the body portion 3, and the bottom portion 5 has a maximum in a direction (DE direction) orthogonal to the axial direction (BC direction). There is an inner diameter portion 5 e, and this maximum inner diameter portion 5 e is located on the end surface 101 a of the bell 101. The fitting portion between the bottom portion 5 and the straight portion 3a of the body portion 3 is sealed so that air in the inner space 21 of the silencer 1, particularly the silencer body 7, does not leak from there. As a result, a stable sound without unevenness can be played in the entire range.
底部５の中央部には、内側に凹ましてベース５ｂが形成され、このベース５ｂからさらに内側に延びる取付筒部５ｃが形成されている。この取付筒部５ｃに、パイプ材２０の端部２０ａを圧入して取り付けて内部空間２１に配置されている。パイプ材２０は、アルミニウムで成形されているが、合成樹脂で成形されてもよく、直線状に形成され、先端２０ｂは、胴部３の傾斜部３ｂの位置まで延びている。 A base 5b is formed at the center of the bottom 5 so as to be recessed inward, and an attachment cylinder 5c extending further inward from the base 5b is formed. The end portion 20a of the pipe member 20 is press-fitted and attached to the mounting cylinder portion 5c and is disposed in the internal space 21. The pipe member 20 is formed of aluminum, but may be formed of a synthetic resin, is formed in a straight line shape, and the tip 20b extends to the position of the inclined portion 3b of the trunk portion 3.
パイプ材２０の内径Ｄ１０は、マウスピース１０２の最小内径Ｄ２０より大きく設定され、このパイプ材２０によって呼気排出通路部８１が設けられ、調整筒３ｇと同じ軸線Ｏ１上に位置している。この呼気排出通路部８１は内部空間２１に連通して呼気を外部空間に排出する。このとき呼気排出通路部８１を音波が通るが、呼気排出通路部８１が音波の通る抵抗になり、外部空間に漏れ出る音量を減少させ、安定して消音効果を高めることが可能である。この呼気排出通路部８１の長さＬ２は、呼気排出通路部８１が音波の通る抵抗になる長さであればよく、特に限定されない。 An inner diameter D10 of the pipe material 20 is set to be larger than a minimum inner diameter D20 of the mouthpiece 102, and an exhalation discharge passage portion 81 is provided by the pipe material 20, and is located on the same axis O1 as the adjustment cylinder 3g. The exhalation discharge passage portion 81 communicates with the internal space 21 and discharges exhalation to the external space. At this time, the sound wave passes through the exhalation discharge passage portion 81, but the exhalation discharge passage portion 81 becomes a resistance through which the sound wave passes, and it is possible to reduce the sound volume leaking to the external space and to stably improve the silencing effect. The length L2 of the exhalation exhaust passage portion 81 is not particularly limited as long as the exhalation exhaust passage portion 81 is a length that allows the sound wave to pass through.
呼気排出通路部８１の断面積は、トランペット１００のマウスピース１０２の内径Ｄ２０の最小径部（スロート）の断面積以上であり、これにより吹奏感に悪影響を与える呼気の直流の流路抵抗の付加的増加を防ぐことが可能となる。トランペット１００のスロート内径はφ３．７ｍｍ程度であるから、パイプ材２０の内径Ｄ１０はこれと同等或いはそれ以上に設定してある。 The cross-sectional area of the exhalation discharge passage portion 81 is equal to or larger than the cross-sectional area of the minimum diameter portion (throat) of the inner diameter D20 of the mouthpiece 102 of the trumpet 100, thereby adding a direct current flow path resistance of exhalation that adversely affects the feeling of blowing. It is possible to prevent an increase. Since the throat inner diameter of the trumpet 100 is about φ3.7 mm, the inner diameter D10 of the pipe material 20 is set to be equal to or greater than this.
このように、ベル１０１に消音器本体７の胴部３を装着するだけで、演奏者の呼気が、呼気導入開口部８０から内部空間２１へ入り、この呼気は呼気排出通路部８１を通って外部空間に排出されて音響モードを閉じモードにすることができる。すなわち、呼気排出通路部８１の通路抵抗により外部への音波の伝播を抑制することで、種々の金管楽器に対応して外部空間に漏れ出る音量を減少させ、安定して消音効果を高めることが可能である。 In this way, the player's exhalation enters the internal space 21 from the exhalation introduction opening 80 by simply attaching the body 3 of the silencer body 7 to the bell 101, and this exhalation passes through the exhalation discharge passage 81. The sound mode can be set to the closed mode by being discharged to the outside space. That is, by suppressing the propagation of the sound wave to the outside by the passage resistance of the exhalation discharge passage portion 81, the volume leaking to the external space corresponding to various brass instruments can be reduced, and the silencing effect can be stably improved. Is possible.
しかも、消音器１をベル１０１に装着したときに、ベル１０１の端面１０１ａに底部５の最大内径部５ｅが位置し、従来品の消音器と消音器１の寸法を比較すると、消音器１を差し込んで装着したときにはベル１０１の端面１０１ａから前方に飛び出す距離が小さくなり、従来品の消音器に比べ、コンパクトで音程バランスを正しく保つことができ、しかも、鳴りむらの無い安定した音を全音域で演奏可能にすることができる。 Moreover, when the silencer 1 is mounted on the bell 101, the maximum inner diameter portion 5e of the bottom 5 is located on the end surface 101a of the bell 101, and when comparing the dimensions of the conventional silencer and the silencer 1, the silencer 1 is When inserted and mounted, the distance that protrudes forward from the end face 101a of the bell 101 is reduced, and it is compact and can maintain a correct pitch balance compared to the conventional silencer. Can be played.
また、呼気排出通路部８１を、パイプ材２０を内部空間２１に配置し、パイプ材２０の端部２０ａを消音器本体７の底部５に取り付けて構成し、呼気排出通路部８１を、消音器本体７の内部に設けている。内部空間２１に連通して呼気を外部空間に排出する所定の長さを有する呼気排出通路部８１を設け、呼気排出通路部８１の通路抵抗により外部への音波の伝播を抑制するから、外部空間に漏れ出る音量を減少させ、安定して消音効果を高めることができ、かつパイプ材２０を取り付けるだけの簡単な消音構造である。
［実施の形態２］
以下、この発明の実施の形態２に係る消音器１を図３に従って説明する。なお、実施の形態１に係る消音器１と同様な構成の箇所は同じ符号を付してその説明を省略する。この実施の形態においては、パイプ材２０を内部空間２１に配置し、このパイプ材２０の端部２０ａを消音器本体７の底部５の側部５に貫通させて取り付けている。このパイプ材２０の端部２０ａは、底部５の底面５ｇの線Ｏ３上から出ないようにしてコンパクトな構成になっている。
