Description
【考案の詳細な説明】
本考案は鍵盤の鍵を指で触れる位置によって音色を異な
らせる様にした電子楽器に関するものである。[Detailed Description of the Invention] The present invention relates to an electronic musical instrument in which the tone color varies depending on the position of the finger on the keyboard.
従来の鍵盤を有する電子楽器は音色変更のための切換ス
イッチを鍵盤とは別の列に有しており、演奏中このスイ
ッチを切換ることによって例えばピアノの音色からオル
ガンの音色に切換る様になされていた。Conventional electronic musical instruments with keyboards have a changeover switch for changing the tone in a row separate from the keyboard, and by switching this switch during performance, you can change, for example, from a piano tone to an organ tone. It had been done.
このため鍵盤から離れた位置の切換スイッチを操作しな
ければならず音色切換操作が非常にわずられしかった。For this reason, it was necessary to operate a changeover switch located far from the keyboard, making it extremely difficult to change tones.
本考案は上述の様な欠点を改善した電子楽器を提供する
もので、以下図面に従って詳細に説明する。The present invention provides an electronic musical instrument that overcomes the above-mentioned drawbacks, and will be described in detail below with reference to the drawings.
図は本考案の一実施例を示すもので基板７に非導電性塗
料で鍵盤が点線の如く描かれており、鍵４の各鍵には検
知手段として共通電極５と音階電極６，６′が印刷配線
され絶縁塗膜でおおわれている。The figure shows an embodiment of the present invention, in which a keyboard is drawn as dotted lines on a substrate 7 with non-conductive paint, and each of the keys 4 has a common electrode 5 and scale electrodes 6, 6' as detection means. is printed and wired and covered with an insulating coating.
この場合音階電極６及び６′はそれぞれ図示の如く上下
に離間して配されているが、共通電極５及び音階電極６
と、共通電極５及び音階電極６′との各組は、それぞれ
の組の両電極のみを同時に一本の指でふれることが出来
る程度に近接して配されこの部分には前記絶縁塗膜が施
されていないので指の接触する検知手段と戒っている。In this case, the scale electrodes 6 and 6' are spaced apart from each other vertically as shown in the figure, but the common electrode 5 and the scale electrode 6'
Each set of common electrode 5 and scale electrode 6' is arranged close enough that only both electrodes of each set can be touched with one finger at the same time. Since this is not done, it is considered a detection method that requires finger contact.
第１の検知手段としての音階電極６は該当する鍵盤位置
に応じて音階信号発生部１に含まれるＦＥＴ９のゲート
に接続される。A scale electrode 6 as a first detection means is connected to the gate of an FET 9 included in the scale signal generator 1 depending on the corresponding keyboard position.
ＦＥＴ９は通常はそのゲートに負電圧８が抵抗１５を介
して接続されているのでオフ状態となっているが、共通
電極５と音階電極６とを指で同時にふれることによって
共通電極５に接続された正電圧１０が指のインピーダン
スを介して前記ゲートに接続されるので、ＦＥＴ９はオ
ン状態となり、抵抗１４が接地されて発振器１１が完結
し、つまり検知手段が作動し所定の音階周波数で発振し
第一の音色の信号を発生する。The FET 9 is normally in an off state because the negative voltage 8 is connected to its gate via the resistor 15, but it can be connected to the common electrode 5 by simultaneously touching the common electrode 5 and the scale electrode 6 with your fingers. Since the positive voltage 10 is connected to the gate through the impedance of the finger, the FET 9 is turned on, the resistor 14 is grounded, and the oscillator 11 is completed, that is, the detection means is activated and oscillates at a predetermined scale frequency. Generate a first tone signal.
こうして得られた各鍵の音階信号は抵抗３により他の音
階信号発生部からの音階信号と加算されてアンプ１２を
介してスピーカ１３に加えられ発音する。The scale signal for each key thus obtained is added to the scale signal from another scale signal generator by the resistor 3, and is applied to the speaker 13 via the amplifier 12 to generate sound.
次に第二の検知手段として共通電極５と音階電極６′と
を指でふれると上述の音階信号発生部１と同一音階であ
るが音色の異なる第二の音階信号発生部２が上述と同様
に動作して第二の音色の異なる音階信号がスピーカ１３
に加えられて発音する様になされている。Next, when the common electrode 5 and the scale electrode 6' are touched with a finger as a second detection means, a second scale signal generator 2 which produces the same scale as the above-mentioned scale signal generator 1 but has a different timbre is generated in the same manner as above. The scale signal with a different second tone is transmitted to the speaker 13.
It is made to be pronounced by adding it to.
なお、上記実施例では鍵盤に指がふれたことを検知する
検知手段として、近接配置された２つの電極を設けたが
、この様な例に限らず、例えば各鍵に電極を設け、この
電極に指がふれると人体に誘起している誘導ハム電圧が
該電極に印加され、これを増幅検波して該当する鍵及び
鍵の位置に相当する音色の音階信号発生回路を動作させ
る様にしてもよい。In the above embodiment, two electrodes placed close to each other were provided as a detection means for detecting the touch of a finger on the keyboard, but the present invention is not limited to this example. For example, an electrode may be provided on each key, and this electrode When a finger touches a finger, the induced hum voltage induced in the human body is applied to the electrode, and this is amplified and detected to operate the scale signal generation circuit of the corresponding key and the tone corresponding to the key position. good.
又上述の場合鍵盤の各鍵は固定されている場合について
示したが通常の鍵盤楽器の様に基板に画かれた隣接した
鍵を溝等で分割して各鍵をそれぞれ独立に動かせる様に
してもよい。Also, in the above case, each key on the keyboard is fixed, but like a normal keyboard instrument, adjacent keys drawn on the board are divided by grooves etc. so that each key can be moved independently. Good too.
そしてこの場合音階信号発生部の各音階毎の切り換えは
通常の如く各鍵の下部に作動検知手段としてスイッチを
設けて、これにより押された鍵に該当する音階信号発生
部を動作されて発音させ、一方各鍵の表面にはそれぞれ
前述の検知手段を設け、該検知手段に指がふれたときは
上記音階信号発生部の音色を変化させる様にしても良い
。In this case, to switch the scale signal generator for each scale, a switch is provided below each key as an operation detection means, as usual, and the scale signal generator corresponding to the pressed key is operated and generated. On the other hand, the above-mentioned detection means may be provided on the surface of each key, and when a finger touches the detection means, the tone color of the scale signal generation section may be changed.
以上の様に本考案によれば演奏特権が各鍵に触れる位置
をずらせるだけで音色が異なる演奏をすることができる
。As described above, according to the present invention, it is possible to perform performances with different tones simply by shifting the position where the performance privilege touches each key.
図は本考案の一実施例を示す。
１．２はそれぞれ音色の異なる音階信号発生部、３は加
算用抵抗、４は鍵、５は共通電極、６，６′は音階電極
