Description

本発明は、電気吹奏楽器の吹奏情報の入力構造に係り、更に詳しくは、演奏者の呼気を良好に検知することができる電気吹奏楽器の吹奏情報の入力構造に関する。   The present invention relates to an input structure for playing information of an electric wind instrument, and more particularly to an input structure for playing information of an electric wind instrument that can satisfactorily detect the exhalation of a performer.

近時、演奏操作を入力として電気信号を出力し、当該出力に基づいて電気音を再生可能な種々の電気楽器が普及するに至っている。ここで、例えば、フルートと同様の吹奏操作により入力を行える電気楽器を構成する場合、その呼気を検知する構造として特許文献1に開示されるタイプのものが知られている。同文献において、フルートタイプの電気楽器は、頭部管を含む管体と、頭部管に設けられた吹き口と、この吹き口の周辺であって頭部管の内面側に設けられたセンサとを備えている。センサは、演奏者の呼気の圧力を検知し、この検知信号を所定制御することにより電気音を再生するようになっている。   In recent years, various electric musical instruments that can output an electric signal using a performance operation as an input and reproduce an electric sound based on the output have come into wide use. Here, for example, in the case of configuring an electric musical instrument that can be input by a blowing operation similar to a flute, a structure disclosed in Patent Document 1 is known as a structure for detecting the expiration. In this document, a flute type electric musical instrument includes a tube including a head tube, a blower provided in the head tube, and a sensor provided around the blower and on the inner surface side of the head tube. And. The sensor detects the exhalation pressure of the performer, and reproduces an electric sound by performing predetermined control on the detection signal.

特開平7−199919号公報JP-A-7-199919

しかしながら、特許文献1の構造にあっては、アコーステッィクタイプのフルートと同様に演奏すると、センサによって呼気の検知を行うことが困難になる、という不都合を招来する。これは、一般に、フルートの演奏では開放空間に息を吹き付けるので呼気の圧力変化が小さくなる他、管体の一端側が開放しているので、センサに達する呼気の圧力が吹き出し時より低下し易くなることに起因する。   However, in the structure of Patent Document 1, if the performance is performed in the same manner as the acoustic type flute, there is a disadvantage that it becomes difficult to detect the expiration by the sensor. In general, in the performance of a flute, since the breathing pressure is blown into the open space, the pressure change of the exhalation becomes small, and since the one end side of the tube is open, the exhalation pressure reaching the sensor is more likely to be lower than when blowing. Due to that.

[発明の目的]
本発明は、このような不都合に着目して案出されたものであり、その目的は、演奏者の呼気の検出を安定して行うことができる電気吹奏楽器の吹奏情報の入力構造を提供することにある。
[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to provide a wind information input structure for an electric wind instrument that can stably detect the exhalation of a performer. There is.

前記目的を達成するため、本発明は、呼気の圧力を検知して電気信号を出力する変換装置と、この変換装置に前記呼気を案内する案内部材とを有する電気吹奏楽器の吹奏情報の入力構造であって、
前記案内部材は、前記呼気の吹き出し方向に沿って軸線方向が位置する本体筒と、この本体筒の一端側に形成されるとともに、演奏者の唇から離れて配置される第1の開口部と、本体筒の他端側に形成されて第1の開口部から前記変換装置に流れる呼気が通過する第2の開口部とを含み、
前記本体筒は、一端側から他端側に向かうに従って次第に開口面積が小さくなる形状を備える、という構成が採用されている。
In order to achieve the above object, the present invention provides an input structure for playing information of an electric wind instrument comprising a conversion device that detects an exhalation pressure and outputs an electrical signal, and a guide member that guides the exhalation to the conversion device. Because
The guide member has a main body cylinder whose axial direction is positioned along the direction of blowing out the exhalation, and a first opening formed on one end side of the main body cylinder and disposed away from the lips of the performer. A second opening that is formed on the other end of the body tube and through which exhaled air flowing from the first opening to the conversion device passes,
The main body cylinder has a configuration in which the opening area gradually decreases from one end side to the other end side.

本発明において、前記本体筒はメガフォン状に設けられ、その軸線長さが第1の開口部の最大内径より長く設定されることが好ましい。   In the present invention, it is preferable that the main body cylinder is provided in a megaphone shape, and its axial length is set longer than the maximum inner diameter of the first opening.

また、前記電気吹奏楽器は、筒状若しくは柱状の頭部管形成体と、当該頭部管形成体と前記案内部材とを連結する連結部とを備え、
前記連結部は、頭部管形成体と案内部材との相対位置を調整可能に設けられる、という構成も好ましくは採用される。
The electric wind instrument includes a cylindrical or columnar head tube forming body, and a connecting portion that connects the head tube forming body and the guide member.
A configuration in which the connecting portion is provided so that the relative position between the head tube forming body and the guide member can be adjusted is also preferably employed.

更に、前記頭部管形成体の外周面には奏者の唇を着座させるためのリッププレートが設けられ、このリッププレートは、前記第1の開口部の近傍に位置するとともに、前記案内部材に非干渉となる形状に設けられる、という構成を採ることが好ましい。   Further, a lip plate for seating the player's lips is provided on the outer peripheral surface of the head tube forming body, and the lip plate is located in the vicinity of the first opening and is not attached to the guide member. It is preferable to adopt a configuration in which it is provided in a shape that causes interference.

本発明によれば、本体筒内を呼気が通過することにより、呼気の圧力を吹き出し時より増大させて変換装置に検知させることができる。これにより、フルートのように呼気の圧力変化が小さくても、当該呼気の圧力やその変化を変換装置により簡単且つ安定的に検出でき、極めて簡単な構造により再生される音の音質を向上することが可能となる。   According to the present invention, when exhalation passes through the main body cylinder, the pressure of the exhalation can be increased from that at the time of blowing, and can be detected by the conversion device. As a result, even if the change in exhalation pressure is small, such as a flute, the exhalation pressure and its change can be detected easily and stably by the converter, and the sound quality of the sound reproduced by an extremely simple structure can be improved. Is possible.

また、連結部により案内部材の位置を調整可能としたので、演奏者が吹奏し易く、呼気の圧力検知が良好に行えるように案内部材を容易にセットすることができる。   Further, since the position of the guide member can be adjusted by the connecting portion, the guide member can be easily set so that the performer can easily play and can detect the pressure of exhalation well.

更に、案内部材に非干渉となるリッププレートを頭部管形成体に設けたので、アコースティックタイプのフルートのように唇及びその周辺をリッププレートに当てた状態で吹奏することができ、演奏感をより安定させることが可能となる。   Furthermore, since the lip plate that does not interfere with the guide member is provided in the head tube forming body, it is possible to play with the lip and its surroundings in contact with the lip plate like an acoustic type flute. It becomes possible to make it more stable.

なお、本明細書及び特許請求の範囲において、「開口面積」とは、本体筒の軸線に直交する面で断面視した場合における当該本体筒の内側の面積を意味する。   In the present specification and claims, the “opening area” means an inner area of the main body cylinder in a cross-sectional view on a plane orthogonal to the axis of the main body cylinder.

The control circuit 30 outputs a signal obtained by converting the electrical signal of the conversion device 16 into wind speed information by the integration circuit, and the signal is stabilized by the low-pass filter circuit. A parameter close to the wind speed is detected. Specifically, the integration circuit integrates electrical signals including pressure information that is strong against the rise of the wind and then weakens, thereby imitating the function of imitating stable wind speed information that is not strong but remains constant. Demonstrate. On the other hand, the low-pass filter circuit exhibits a function of cutting only high-frequency signal components and allowing only DC stable signals to pass. The control device 30 is also provided so as to be able to control signals from the respective keys of the flute forming body 11 described above, and can also adjust the pitch and pitch of the reproduced sound from the reproducing device.

前記連結部17は、頭部管形成体19を貫通するとともに、リッププレート12の図2中左右両側にそれぞれ位置する一対の保持部材32,32と、これら保持部材32,32の同図中下部間を連結するとともに、頭部管形成体19と略平行に延びるバー33と、このバー33に支持されて図1中左上方向に湾曲しながら延びるレール部材34と、このレール部材34の延出方向に沿って移動可能なスライダ36と、このスライダ36に支持されるとともに、前記案内部材13を図1中紙面直交方向両側から挟み込む挟持部材37とを備えている。レール部材34とスライダ36との間には、図示しないストッパが設けられ、このストッパにより、スライダ36がレール部材34に沿う任意の位置で移動規制される。従って、レール部材34及びスライダ36を介して案内部材13の位置及び向きを変えることができ、ひいては、案内部材13に対して吹奏し易く、且つ、呼気が案内部材13内に良好に吹き込まれるよう、頭部管形成体19や演奏者Pの唇と案内部材13との相対位置や相対角度を調整可能となる。   The connecting portion 17 penetrates the head tube forming body 19 and is located at the left and right sides of the lip plate 12 in FIG. 2, respectively, and a lower portion of the holding members 32, 32 in the drawing. A bar 33 extending substantially parallel to the head tube forming body 19, a rail member 34 supported by the bar 33 and extending while bending in the upper left direction in FIG. 1, and an extension of the rail member 34 The slider 36 is movable along the direction, and the holding member 37 is supported by the slider 36 and sandwiches the guide member 13 from both sides in the direction orthogonal to the paper surface in FIG. A stopper (not shown) is provided between the rail member 34 and the slider 36, and the slider 36 is restricted from moving at any position along the rail member 34 by the stopper. Therefore, the position and orientation of the guide member 13 can be changed via the rail member 34 and the slider 36, and as a result, it is easy to blow against the guide member 13, and the exhaled air is well blown into the guide member 13. The relative position and relative angle between the head tube forming body 19 and the lips of the player P and the guide member 13 can be adjusted.

以上の構成において、電気吹奏楽器10を演奏する場合、案内部材13の位置及び向きを調整した後、フルートと同様に吹奏を行えばよい。具体的には、リッププレート12に下唇P1及びその周辺を当接し、下唇P1及び上唇P2から案内部材13の第1の開口部21を離した状態で、当該第1の開口部21に向かって下唇P1及び上唇P2間から呼気を吹き込む。これにより、本体筒20の内部、第2の開口部22及び流通路15を経て呼気が変換装置16に流れ込む。ここで、本体筒20は前述のようなメガフォン状をなすので、本体筒20の内部に呼気が集まるに従って、その圧力が増大することとなり、第1の開口部21の通過時における呼気の圧力より大きい圧力が変換装置16に送出されることとなる。   In the above configuration, when the electric wind instrument 10 is played, after the position and orientation of the guide member 13 are adjusted, the wind may be performed in the same manner as the flute. Specifically, the lower lip P1 and the periphery thereof are brought into contact with the lip plate 12, and the first opening 21 of the guide member 13 is separated from the lower lip P1 and the upper lip P2, so that the first opening 21 The exhalation is blown in between the lower lip P1 and the upper lip P2. Thereby, exhaled air flows into the conversion device 16 through the inside of the main body cylinder 20, the second opening 22 and the flow passage 15. Here, since the main body cylinder 20 has a megaphone shape as described above, the pressure increases as the exhalation collects inside the main body cylinder 20, and the expiratory pressure when passing through the first opening 21 is increased. A large pressure is sent to the conversion device 16.

従って、このような実施形態によれば、極めて簡単な構成により、演奏者Pの吹き出し直後の呼気の圧力を効率良く高め、変換装置16によるセンシングの精度を向上させることができる。これにより、変換装置16において、演奏者Pによる呼気の圧力変化に応じて電気信号の出力を簡単に変化させることが可能となり、安定感に優れた良好な音質の再生音が得られるという効果を得る。   Therefore, according to such an embodiment, with a very simple configuration, the pressure of exhalation immediately after the performer P is blown out can be efficiently increased, and the accuracy of sensing by the conversion device 16 can be improved. As a result, the conversion device 16 can easily change the output of the electric signal in accordance with the change in exhalation pressure by the player P, and an effect of obtaining a reproduced sound with excellent stability and excellent sound quality can be obtained. obtain.
