Description
(i)響板33の上に砂等の細かい粒状物を散布して、周波数を徐々に変化させながら響板33を自由振動させる。
(ii)響板33の固有周波数と一致すると、響板33上の粒状物が節線に集まってくるので、その際の粒状物の集合状態から、節線の位置を各固有周波数毎に把握する。
(iii)響板33に対応する平面上に各固有周波数毎の節線を重畳させる。
(iV)重畳された節線の密度が「粗」となっている場所を特定する。
(V)節線の密度が「粗」となっている場所を、トランスデューサの配置位置として決定する。
Claims (2)
- 板状部材から成る響板を有し、該響板を振動させて楽音を発生させる電子鍵盤楽器であって、
音高情報を入力するための操作子であって音高順に配列された複数の演奏操作子と、
同一響板に取り付けられた第1、第2の加振器と、
前記複数の演奏操作子の操作に応じた演奏信号を生成し、該演奏信号を前記入力された音高情報に応じた周波数に基づいた出力バランスに分配するような前記第1の加振器用の第1の駆動信号及び前記第2の加振器用の第2の駆動信号をそれぞれ生成し出力する信号生成出力手段とを有し、
前記複数の演奏操作子の配列方向において、前記第1の加振器は、前記第2の加振器よりも低音側の位置に配置され、前記響板の奥行きは、前記複数の演奏操作子の配列方向において前記第1の加振器が配置されている位置よりも前記第2の加振器が配置されている位置の方が短く、
前記第1の加振器は前記第2の加振器よりも大きく且つ担当音域が低く、前記第1の加振器は前記信号生成出力手段により出力された前記第1の駆動信号によって駆動されて前記響板を振動させ、
前記第2の加振器は前記信号生成出力手段により出力された前記第2の駆動信号によって駆動されて前記響板を振動させ、
前記信号生成出力手段は、前記第1の駆動信号と前記第2の駆動信号との出力バランスに関して、前記第2の加振器の担当音域においては前記第1の駆動信号及び前記第2の駆動信号のうち前記第2の駆動信号の出力レベルが高くなるようにする一方、前記第1の加振器の担当音域においては前記第1の駆動信号及び前記第2の駆動信号のうち前記第1の駆動信号の出力レベルが高くなるようにすることを特徴とする電子鍵盤楽器。 - 前記信号生成出力手段は、前記第1、第2の各加振器の特性及び配置位置に応じて前記駆動信号を生成し出力することを特徴とする請求項1記載の電子鍵盤楽器。
