Description
これに対して、本発明においては、駒が弦の張設方向と直交する方向に回動または揺動する力が作用すると、支持体の撓み変形部のみが変形して固定部は殆ど動かない。したがって、固定部側の脚部の動きを圧電変換手段が拾うことがなく、信号の干渉が起きるようなことがない。
図1は本発明を電気チェロに適用した一実施の形態を示す正面図、図2は図1のII−II線拡大断面図、図3は駒取付部の平面図、図4は同駒取付部の支持体を取り外した平面図、図5〜図8は周波数応答特性を示す図である。なお、従来技術の欄で示した構成部材、部分と同一のものについては同一符号をもって示し、その説明を適宜省略する。
測定に使用した楽器は、電気チェロである。従来装置における測定に際しては、音圧が本発明と略同等となる程度に出力をかさ上げしてある。なお、図5〜図8において、実線で示す「横」表記のデータは駒の回動方向を想定し、破線で示す「高音縦」表記データは高音側弦の伸縮方向の動きを想定してインパルスハンマーを使用した。
測定に際しては、1kHzから4kHzの領域で略同程度になるように調整してある。この図から読み取れることは、基音領域での応答は本発明の方が大きく、4〜7kHzもまた本発明が大きいということで、耳につき易い1kHzから4kHzの領域で略同程度なのに、基音領域で本発明の応答が大きいということは、本発明の方がパワー感があり、かつ煌びやかな音色であるといえる。
この図から上記各種説明に対して、2事例の差を示すものとなっている。
