Description
本考案は内部に人の手が入る人形の形状をした電子楽器に関する。 The present invention relates to an electronic musical instrument in the shape of a doll into which a human hand enters.
本出願人は実願２００５−４５８２において、パペットの内部に手を入れて、その手の連続的な動きや力等の物理量変化に応じて音の高さが変わる楽器を提案している。 In the actual application 2005-4582, the present applicant has proposed a musical instrument in which the pitch of a puppet is changed according to changes in physical quantities such as continuous movement and force of the puppet.
これはパペットの口の開度やその他の部分の動きに応じて音の周波数が変わることで、あたかもパペットが歌っているように感じさせて楽しさを大きくすることを狙った考案である。 The idea is to increase the enjoyment by making the puppet feel as if it is singing by changing the frequency of the sound according to the opening of the puppet's mouth and the movement of other parts.
この場合に例えば口の開度は連続的に変化するものであるが、この口の開度に連続的に比例させて音の高さを変えるとすると、音楽の演奏が非常に繊細で難しいものになる。 In this case, for example, the opening degree of the mouth changes continuously, but if the pitch is changed in proportion to the opening degree of the mouth, music performance is very delicate and difficult. become.
これは通常演奏される音楽が、音階に従っているために、楽器から出る音がこの音階から外れると非常に聞き苦しいものになる。聞いて心地よい音楽にするためには正確に音階に従った音を出す必要があるために、連続的に周波数の変わる楽器の場合は正確な音の高さに瞬時に合わせ込む必要があり、このため非常に繊細な操作が要求されることによるものである。 This is because it is very hard to hear if the music that is played is out of this scale because the music that is normally played follows the scale. In order to make music comfortable to listen to, it is necessary to produce a sound that exactly follows the scale, so in the case of instruments with continuously changing frequencies, it is necessary to adjust to the exact pitch instantly. This is because a very delicate operation is required.
本考案では、口の開度その他の演奏者の連続的な動きや物理量の変化による操作に応じて楽器から発される音の高さが、段階的に変化するようにしたものである。 In the present invention, the pitch of the sound emitted from the musical instrument is changed in a stepwise manner in accordance with an operation based on a change in the opening of the mouth or other performers or a physical quantity.
このことにより、パペットの動きや加える力等に応じて楽器から出る音が自動的に音階に従うようにすることが出来るようになる。 As a result, the sound emitted from the musical instrument can automatically follow the scale according to the movement of the puppet, the applied force, and the like.
例えば、図１に示すように、１オクターブ分変化する物理量を７等分してＣ（ハ）〜Ｂ（ロ）まで、ハ長調ならド〜シまでに対応させる。 For example, as shown in FIG. 1, a physical quantity that changes by one octave is divided into seven equal parts from C (C) to B (B), and in C major, from Do to D.
或いは図２に示すように、１オクターブ分変化する物理量を１２等分して半音毎にＣからＢまでに対応させる。 Alternatively, as shown in FIG. 2, a physical quantity that changes by one octave is divided into 12 equal parts so as to correspond from C to B for each semitone.
図１の例ではハ長調、イ短調を基準にしているが、もちろん他の調であっても良い。 In the example of FIG. 1, C major and A minor are used as a reference, but other keys may be used.
また、ここで図示しているのは１オクターブ分に限っているが、実際には数オクターブに渡って変換を行うのが普通である。 In addition, the figure shown here is limited to one octave, but in practice, conversion is usually performed over several octaves.
図１，２の横軸は物理量としているが、具体的にはパペットの口の開度や手足の動きや演奏者の加える力の強さ等のことである。 The horizontal axis in FIGS. 1 and 2 is a physical quantity. Specifically, the opening of the puppet's mouth, the movement of the limbs, the strength of the force applied by the player, and the like.
楽器から発する音の音高を視認できる表示部を設けることによって、更に演奏を容易にすることが出来る。 Performance can be further facilitated by providing a display unit that can visually recognize the pitch of the sound emitted from the musical instrument.
上述したように本考案の電子楽器は、演奏者の連続的な動きや物理量の変化を音階に従った音程の音に変換することによって、この楽器を初めて手にする人にも直感的に容易に演奏をすることが出来るようにするものである。 As described above, the electronic musical instrument of the present invention is intuitively easy for those who are new to this instrument by converting the player's continuous movements and changes in physical quantities into pitches according to the scale. It is intended to be able to perform.
更に楽器から発する音の音高を視認できる表示部を設けることによって、音の出だしから正確な音高の演奏をすることが出来る Furthermore, by providing a display unit that can visually recognize the pitch of the sound emitted from the musical instrument, it is possible to perform an accurate pitch from the beginning of the sound.
パペットの口の開度を検出するセンサを配置し、このセンサの出力に対応した音階に従った音程の変化が生じる電子楽器をパペットの内部に組み込む。 A sensor for detecting the opening degree of the puppet's mouth is arranged, and an electronic musical instrument that causes a change in pitch according to the scale corresponding to the output of this sensor is incorporated in the puppet.
音高の表示部を演奏者からの視認性の良い位置に配置する。 The pitch display section is arranged at a position that is highly visible from the performer.
図３に、本電子楽器を左手で操作している一例の断面図を示す。１はパペット。この例は口が開閉できるタイプで動作検出部２として口の開度のセンサを備えている。このセンサは例えばパペットの上顎と下顎の回転軸に可変抵抗を配置する。 FIG. 3 shows a cross-sectional view of an example in which the electronic musical instrument is operated with the left hand. 1 is a puppet. In this example, the mouth can be opened and closed, and a mouth opening sensor is provided as the motion detector 2. In this sensor, for example, variable resistances are arranged on the rotation axes of the upper and lower jaws of the puppet.
３は力検出部。この例では、パペットの右手の中に圧力を検出するセンサを備えている。この他にどのような物理量の変化を利用しても良い 3 is a force detector. In this example, a sensor for detecting pressure is provided in the right hand of the puppet. Any other physical quantity change may be used.
４は制御回路部。２からの開度情報から図１〜３に示す変換方式に従った音階に変換して音声信号を発生する。５は増幅部。６は電源部。この例では乾電池を想定している。７は電気信号を音に変換するスピーカー。８は音高の表示部である。 4 is a control circuit unit. 1 is converted into a scale according to the conversion method shown in FIGS. 5 is an amplification unit. 6 is a power supply part. In this example, a dry battery is assumed. 7 is a speaker that converts electrical signals into sound.
音高は、例えばピアノ鍵盤の中央のド、つまり２６３Ｈｚ付近であれば４Ｃ、というように数字とＡ〜Ｆまでのアルファベット、それに＃、♭の組み合わせで表示できる。 The pitch can be displayed with a combination of a number, an alphabet from A to F, and # and ♭, for example, the center of the piano keyboard, that is, 4C if it is around 263 Hz.
図４に電圧に変換後の物理量を音高に相当する電圧に変換する回路の一例を示す。
連続的に変化する入力側の電圧を段階的な電圧に変換することが出来る。
抵抗値を変えることで音階を決定することが出来る。FIG. 4 shows an example of a circuit that converts a physical quantity converted into a voltage into a voltage corresponding to a pitch.
The continuously changing voltage on the input side can be converted into a stepped voltage.
The scale can be determined by changing the resistance value.
演奏者は左手で口の開閉操作を行い、右手はパペットの右手を握る。右手の握力で音の大きさを制御し、左手で操作する口の開度を通して音の高さを制御する。音の高さと大きさの制御は左右の手で逆であっても良い。 The performer opens and closes the mouth with his left hand, and the right hand holds the right hand of the puppet. The volume of the sound is controlled by the grip strength of the right hand, and the pitch of the sound is controlled through the opening of the mouth operated with the left hand. The control of the pitch and loudness may be reversed with the left and right hands.
