Abstract

To provide an air lead musical instrument having a structure that allows even those with poor playing ability such as beginners to easily produce sound.SOLUTION: An air lead musical instrument has a structure in which a blow port 3 is provided in a song port 2 of a cylindrical tube having an outer surface corresponding to a lip plate. The blow port 3 comprises: a hole to a discharge port 5 from an opening end 4 into which exhaled air is blown; a convex part 9 that controls the direction of the exhaled air flowing out from the song port 2; a surface that is connected to the convex part 9 and closes the upper opening end of the song port 2; and a side wall 6 that fixes the blow port 3 to the song port 2. The exhaled air having been blown into the opening end 4 is ejected from the discharge port 5 and flows into the song port 2. The exhaled air then circulates in a head tube 1, and flows out from the song port 2 along the convex part 9. The exhaled air flowing into the song port 2 and the exhaled air flowing out from the song port collide and coalesce near the surface of the convex part 9, and then go out of the song port 2 to exert an air lead function and produce a sound. A path through which the exhaled air having been blown into the opening end 4 goes out to the outside of the song port 2 is a windway, and this path is formed, so that the air lead musical instrument can easily produce a sound.SELECTED DRAWING: Figure 1

Description

本発明は、初心者のような演奏能力の乏しい人でも音を出すことが容易なエアリード楽器に関するものである。 The present invention relates to an air lead musical instrument in which even a person with poor playing ability, such as a beginner, can easily produce a sound.

エアリード楽器の例として、フルートおよびリコーダがある。フルートの演奏者は、リッププレートに下唇を押し当てて特定のアンブシュア（唇の形）を作って、唄口の内壁に呼気を吹き付けて演奏する。フルートの演奏者は、アンブシュア、呼気、トーンホール（音孔）の開閉などを調節することで広い音域に渡って豊かな音を出すことができる。 Examples of air-lead musical instruments are flutes and recorders. The flute player presses the lower lip against the lip plate to create a specific embouchure (lip shape) and blows exhaled air onto the inner wall of the singing mouth. A flute player can produce a rich sound over a wide range by adjusting the embouchure, exhalation, opening and closing of tone holes (sound holes), and so on.

しかし、アンブシュアを調節することは、演奏者の能力に大きく依存する。このため、初心者などの演奏能力の乏しい人がフルートの音を出すことは困難であった。 However, adjusting the embouchure depends largely on the ability of the performer. For this reason, it was difficult for a person with poor playing ability, such as a beginner, to produce a flute sound.

これに対して、リコーダにはウインドウェイ（呼気の流れる道）が設けられている。そのため、演奏者がウインドウェイの吹き口から呼気を吹き込むと、呼気は他方の吐出口から噴出してエッジに導かれ、容易に音を出すことができる。 On the other hand, the recorder is provided with a windway (a path through which exhaled breath flows). Therefore, when the performer blows exhaled air from the outlet of the windway, the exhaled air is ejected from the other outlet and guided to the edge, so that sound can be easily produced.

解決しようとする問題点は、初心者のような演奏能力の乏しい人はフルートの音を出すことが困難な点である。 The problem to be solved is that it is difficult for a person with poor playing ability, such as a beginner, to produce a flute sound.

本発明は、演奏者がフルートのリッププレートに下唇を押し当てて特定のアンブシュアを作り、音を出すときの呼気の流れる道、即ち、ウインドウェイに相当する構造をリッププレート上に設けて、音が出るようにしたことを最も主要な特徴とする。 In the present invention, the player presses the lower lip against the lip plate of the flute to create a specific embouchure, and provides a structure on the lip plate that corresponds to a windway, that is, a path through which exhaled sound flows when making a sound. The most important feature is that it produces sound.

本発明のフルートは、リッププレート上に呼気を導く吹き口を設けたので、初心者でも容易に音が出せる。また、この吹き口はフルートの音色やキー操作を変えないという利点がある。 Since the flute of the present invention is provided with an outlet for guiding exhaled air on the lip plate, even a beginner can easily make a sound. In addition, this outlet has the advantage of not changing the tone of the flute or key operations.

初心者でも容易にフルートの音が出せるという目的を、リッププレート上に吹き口を設けて、音色を損なわずに実現した。 The purpose of making the flute sound easy even for beginners was realized by providing a blower on the lip plate without spoiling the tone.

図１は、本発明フルートの実施例の吹き口断面を含む見取り図、図２は吹き口の縦断面図、図３は横断面図である。 FIG. 1 is a sketch including a cross section of an air outlet according to an embodiment of the flute of the present invention, FIG. 2 is a vertical sectional view of the air outlet, and FIG. 3 is a cross-sectional view.

吹き口３の開口端４から呼気を吹き込むと、呼気は他方の吐出口５から噴出し、唄口２の内壁７に吹き付けられる。次いで、呼気は頭部管１の内壁８に沿って周回した後、四分円形の凸部９に沿って流れ、唄口２から流出する。このとき、唄口２に流入する呼気と流出する呼気は、凸部９の表面付近で衝突してエアリード機能を発揮し、音が出る。 When exhaled air is blown from the opening end 4 of the air outlet 3, the exhaled air is ejected from the other discharge port 5 and is blown onto the inner wall 7 of the song port 2. Next, the exhaled breath circulates along the inner wall 8 of the head tube 1, then flows along the quadrant convex portion 9, and flows out from the singing mouth 2. At this time, the exhaled air flowing into the song mouth 2 and the exhaled air flowing out collide with each other near the surface of the convex portion 9 to exert an air lead function, and a sound is produced.

吐出口５は唄口２の前縁近くに位置し、凸部９の下側は唄口２の約半分を覆っている。吐出口５から噴出した呼気は、唄口２の内壁７に向かって進む途中、唄口２から流出する呼気と衝突する。衝突して合体した呼気は、二つの呼気の進行方向の中間方向に進み、唄口２の外へ流出する。頭部管１内の空気圧は、唄口２に流入する呼気が加圧し、衝突して唄口２から流出する呼気が減圧する。こうして、管内の空気圧の加圧−減圧が繰り返されて音波を生成する。 The discharge port 5 is located near the front edge of the song port 2, and the lower side of the convex portion 9 covers about half of the song port 2. The exhaled air ejected from the discharge port 5 collides with the exhaled air flowing out from the song port 2 on the way toward the inner wall 7 of the song port 2. The explosives that have collided and coalesced proceed in the intermediate direction of the traveling directions of the two exhalations, and flow out of the singing mouth 2. The air pressure in the head tube 1 is pressurized by the exhaled air flowing into the singing mouth 2, and the exhaled air flowing out of the singing mouth 2 collides with the singing mouth 2 is decompressed. In this way, pressurization and depressurization of the air pressure in the pipe are repeated to generate sound waves.

このように、本発明フルートのウインドウェイとは、開口端４から吹き込まれて唄口２に流入する呼気と、頭部管１の内壁８に沿って周回した後、唄口２から流出する呼気が衝突して、合体した呼気が唄口２から流出するまでの呼気の流れる道を指す。 As described above, the windway of the flute of the present invention refers to the exhaled breath that is blown from the opening end 4 and flows into the singing mouth 2, and the exhaled air that circulates along the inner wall 8 of the head tube 1 and then flows out from the singing mouth 2. Refers to the path through which the exhaled air flows until the combined exhaled air flows out from the song mouth 2 due to the collision.

リッププレート上に吹き口を設けたフルートは音が出し易いので、初心者の利用が増加すると見込まれる。また、フルートを中断した人も再び演奏を試みることが期待できる。 A flute with a blower on the lip plate is easy to make sound, so it is expected that the use of beginners will increase. Also, the person who interrupted the flute can be expected to try playing again.

Therefore, when the performer blows exhaled air from the outlet of the windway, the exhaled air is ejected from the other outlet and guided to the edge, so that sound can be easily produced.

解決しようとする課題は、初心者のような演奏能力の乏しい人はエアリード楽器の音を出すことが困難な点である。 The problem to be solved is that it is difficult for a person with poor playing ability, such as a beginner, to produce the sound of an air lead instrument.

本発明は、エアリード楽器の音が容易に出るようにするため、頭部管の唄口に吹き口を設けたことを最も主要な特徴とする。The most important feature of the present invention is that a blow port is provided at the singing mouth of the head tube so that the sound of the air lead musical instrument can be easily output.

本発明のエアリード楽器は、唄口に吹き口を設けることでウインドウェイを形成して、呼気を吹き込むと容易に音が出る。また、このエアリード楽器は音色やキー操作が従来の楽器と変わらないという利点がある。In the air lead musical instrument of the present invention, a windway is formed by providing a blow port in the singing mouth, and a sound is easily produced when exhaled breath is blown. In addition, this air lead musical instrument has the advantage that the tone and key operations are the same as those of conventional musical instruments.

図１は本エアリード楽器の吹き口断面を含む見取り図である。FIG. 1 is a sketch including a cross section of the air outlet of the air lead musical instrument. 図２は本エアリード楽器の吹き口の断面図である。FIG. 2 is a cross-sectional view of the air outlet of the air lead musical instrument. 図３は本エアリード楽器の断面図である。FIG. 3 is a cross-sectional view of this air lead musical instrument.

エアリード楽器の音が容易に出せるという目的を、唄口に吹き口を設けることで、音色やキー操作を変えずに実現した。By providing an outlet in the singing mouth, the purpose of easily producing the sound of an air lead instrument was realized without changing the tone and key operation.

図１は、本エアリード楽器の吹き口を頭部管軸に垂直な面で切断したときの断面を含む接合部側の概観図である。図２は、図１と同じ状態の断面図である。図３は、頭部管軸を含む垂直な面を吐出口まで平行移動した面で切断したときの断面図である。FIG. 1 is an overview view of the joint portion side including a cross section when the air outlet of the air lead musical instrument is cut in a plane perpendicular to the head tube axis. FIG. 2 is a cross-sectional view in the same state as in FIG. FIG. 3 is a cross-sectional view when a vertical surface including the head tube axis is cut by a surface translated to the discharge port.

本件発明エアリード楽器の実施形態は、肉厚の円筒管の唄口２に吹き口３を設ける構造である。従来のエアリード楽器の頭部管は、薄肉円筒管にライザーを間に挟んでリッププレートがロウ付けされている。本発明の頭部管１は、従来の頭部管の薄肉円筒管、ライザー、リッププレートの３部品を合わせた厚さと等しい肉厚の円筒管であり、その外表面は従来のリッププレート表面と同じ高さを有し、リッププレートと同等の機能を果たす。この点以外は従来の頭部管と同じ構造をしている。An embodiment of the air lead musical instrument of the present invention has a structure in which a blow port 3 is provided in a song port 2 of a thick cylindrical tube. In the head tube of a conventional air lead musical instrument, a lip plate is brazed with a riser sandwiched between thin-walled cylindrical tubes. The head tube 1 of the present invention is a cylindrical tube having a thickness equal to the combined thickness of the thin-walled cylindrical tube, riser, and lip plate of the conventional head tube, and the outer surface thereof is the same as the surface of the conventional lip plate. It has the same height and performs the same function as a lip plate. Except for this point, it has the same structure as the conventional head tube.

頭部管１の唄口２は、従来のエアリード楽器と同じ楕円形あるいは長方形の四隅が丸い孔である。図１〜図３は、唄口２が楕円形の場合の形状を示している。楕円の長径は頭部管軸と平行方向に位置し、短径は頭部管軸と直交方向に位置する。The singing mouth 2 of the head tube 1 is an elliptical or rectangular hole with rounded corners, which is the same as that of a conventional air lead musical instrument. 1 to 3 show the shape when the song mouth 2 is oval. The major axis of the ellipse is located parallel to the head tube axis, and the minor axis is located orthogonal to the head tube axis.

吹き口３は、開口端４から吐出口５までの通気孔と、呼気が唄口２から流出する方向を制御する凸部９と、唄口２の上部開口端を塞ぐ半楕円形の底面と、吹き口３を唄口２に固定する側壁６とからなる。The air outlet 3 has a ventilation hole from the opening end 4 to the discharge port 5, a convex portion 9 that controls the direction in which exhaled air flows out from the song port 2, and a semi-elliptical bottom surface that closes the upper opening end of the song port 2. , It is composed of a side wall 6 for fixing the blow port 3 to the song port 2.

開口端４から吐出口５までの通気孔は、断面が徐々に狭くなって呼気の流速を早める構造である。吐出口５は細長い隙間（スリット）で、呼気を集束させて噴出する。吐出口５は唄口２の中心より周辺側にずれた位置の上にあり、吐出口５の長辺は唄口２の楕円の長径と平行である。吐出口５を含む面で、吐出口５の中心に垂線を立てて延伸すると、内壁７と交差する。The ventilation holes from the opening end 4 to the discharge port 5 have a structure in which the cross section is gradually narrowed to increase the flow rate of exhaled air. The discharge port 5 is an elongated gap (slit) that focuses and ejects exhaled air. The discharge port 5 is located above a position deviated from the center of the song port 2 to the peripheral side, and the long side of the discharge port 5 is parallel to the major axis of the ellipse of the song port 2. When a perpendicular line is erected at the center of the discharge port 5 on the surface including the discharge port 5 and extended, the surface intersects the inner wall 7.

凸部９の断面は扇形で近似される。扇形の弧の上端は吐出口５の下側長辺と接合し、弧の下端は唄口２の長径の上に重なる。凸部９を長手方向に伸ばした両端は側壁６と接合する。凸部９の弧の下端長辺には、吹き口３の底面が連なる。この底面は、唄口２の楕円形を長径で分割したときにできる半楕円形で、吐出口５とは反対側の唄口２の上部開口端を覆う。凸部９とそれに続く半楕円形の底面は、唄口２から流出する呼気の方向を制御する。The cross section of the convex portion 9 is approximated by a fan shape. The upper end of the fan-shaped arc is joined to the lower long side of the discharge port 5, and the lower end of the arc overlaps the major axis of the song port 2. Both ends of the convex portion 9 extending in the longitudinal direction are joined to the side wall 6. The bottom surface of the blow port 3 is connected to the long side of the lower end of the arc of the convex portion 9. The bottom surface is a semi-elliptical shape formed when the elliptical shape of the song opening 2 is divided into major diameters, and covers the upper opening end of the song opening 2 on the opposite side of the discharge port 5. The convex portion 9 and the semi-elliptical bottom surface following it control the direction of exhalation flowing out from the singing mouth 2.

側壁６の上部は、開口端４から吐出口５までの通気孔と連続した構造で、通気孔を支える。また、側壁６は、凸部９とそれに続く半楕円形の底面部分をとり囲んで連続する一体の構造である。側壁６の底面部は、頭部管１の外表面の曲率と同じ円筒状の凹面を有し、唄口２の上部開口端の周囲に固定される。このように、側壁６は吹き口３の各部構造と一体結合して支えるとともに、吹き口３を頭部管１に固定する。The upper portion of the side wall 6 has a structure continuous with the ventilation holes from the opening end 4 to the discharge port 5, and supports the ventilation holes. Further, the side wall 6 has an integral structure that surrounds the convex portion 9 and the semi-elliptical bottom surface portion that follows the convex portion 9 and is continuous. The bottom surface of the side wall 6 has a cylindrical concave surface having the same curvature as the outer surface of the head tube 1, and is fixed around the upper open end of the song opening 2. In this way, the side wall 6 is integrally coupled with and supported by the structure of each part of the blow port 3, and the blow port 3 is fixed to the head tube 1.

本発明のエアリード楽器は、肉厚の円筒管の唄口２に吹き口３を設ける構造だが、円筒管と吹き口３を一体構造としても良い。また、従来あるエアリード楽器のリッププレートに吹き口３を固定しても同じ機能を果たす。The air lead musical instrument of the present invention has a structure in which a blow port 3 is provided in a singing port 2 of a thick cylindrical tube, but the cylindrical tube and the blow port 3 may be integrated. Further, even if the outlet 3 is fixed to the lip plate of a conventional air lead musical instrument, the same function is achieved.

本件発明が実施されたとき、従来のエアリード楽器と異なる点はウインドウェイが形成されることである。開口端４から呼気を吹き込むと他方の吐出口５から噴出し、さらに唄口２に流入して内壁７と衝突する。次いで呼気は頭部管１の中を周回した後、唄口２の上部開口端の塞がれた面から凸部９に沿って流れる。この呼気は流入する呼気に対してほぼ真横から衝突し、合体して唄口２の外に出る。開口端４から流入して唄口２の外に出るところまでが、本エアリード楽器のウインドウェイであり、頭部管１に吹き口３を設けることで形成される。When the present invention is implemented, the difference from the conventional air lead musical instrument is that a windway is formed. When exhaled air is blown from the opening end 4, it is ejected from the other discharge port 5, further flows into the song port 2, and collides with the inner wall 7. The exhaled breath then circulates in the head tube 1 and then flows along the convex portion 9 from the closed surface of the upper open end of the song opening 2. This exhaled air collides with the inflowing exhaled air from almost the side, coalesces and goes out of the singing mouth 2. The window from the opening end 4 to the point where it flows in and goes out of the singing port 2 is the windway of the air lead musical instrument, and is formed by providing the blowing port 3 in the head tube 1.

ウインドウェイが形成されると、頭部管１の管内の空気圧は、唄口２に流入する呼気が加圧し、流出する呼気が減圧する。管内の空気圧の加圧−減圧が繰り返されて音となる。このエアリード機能を発揮する状態は、凸部９に沿って唄口２から流出する呼気が、流入する呼気と衝突・合体して唄口２の外に押し出す効率が高いときである。吹き口３の構造を適切に調節することで、この状態が生まれる。When the windway is formed, the air pressure in the head tube 1 is pressurized by the exhaled air flowing into the song port 2, and the exhaled air flowing out is decompressed. Pressurization-decompression of the air pressure in the pipe is repeated to make a sound. The state in which the air lead function is exhibited is when the exhaled air flowing out from the singing port 2 along the convex portion 9 collides with and coalesces with the inflowing exhaled air and is pushed out of the singing port 2 with high efficiency. This state is created by appropriately adjusting the structure of the outlet 3.

頭部管の唄口に吹き口を設けたエアリード楽器は音が出し易いので、初心者の利用が増加すると見込まれる。また、エアリード楽器を中断した人が再び演奏を試みることが期待できる。Airlead musical instruments with a blower at the singing mouth of the head tube are expected to increase the use of beginners because they can easily produce sound. Also, it can be expected that the person who interrupted the air lead instrument will try to play again.

Claims (1)

リッププレート上に設けた吹き口の開口端から呼気を吹き込むと、他方の吐出口から呼気が噴出し、唄口の内壁に吹き付けられる。次いで、呼気は頭部管の内壁に沿って周回した後、四分円形の凸部に沿って流れ、唄口から流出する。このとき、唄口に流入する呼気と流出する呼気は、四分円形の凸部の表面付近で衝突してエアリード機能を発揮し、音が出ることを特徴とするフルート。 When exhaled air is blown from the open end of the outlet provided on the lip plate, the exhaled air is ejected from the other discharge port and is blown onto the inner wall of the singing port. The exhaled breath then orbits along the inner wall of the head tube, then flows along the quadrant convex and exits the singing mouth. At this time, the exhaled air flowing into the singing mouth and the exhaled air flowing out collide with each other near the surface of the convex portion of the quadrant to exert the air lead function, and the flute is characterized in that sound is produced.
