Description
図1は、本発明の第1の実施の形態に係る回路が適用される楽器のブロック図である。本楽器1として、例えばギターが例示される。楽器1は、不図示のボディ、ネック、ナット、サドル、ブリッジ、および弦などの一般的なアコースティックギターが備える構成に加えて、図1に示す変換部10、処理部200、トランスデューサ30などを備えている。ボディは内部空間が形成されるように組み立てられた不図示の表板、裏板、側板を有し、表板にネックが連結されている。ボディにブリッジを介して配設されているサドルと、ネックに配設されているナットとの間に弦が張設されている。変換部10は例えば、ブリッジに対して表板を挟んで対向する、表板の内部空間側に配設されている。変換部10は例えば、ピエゾピックアップを有し、弦の振動を電気信号である信号S1に変換して処理部200に出力する。処理部200は入力された信号S1に対して所定の信号処理を行い、信号S3をトランスデューサ30へ出力する。トランスデューサ30は、例えば表板に配設されており、信号S3に基づいて表板に振動を加える。例えば演奏者により弦に振動が加えられると、弦の振動に基づいて共鳴するボディから生音が放射されるとともに、トランスデューサ30がボディに加える振動に基づいて共鳴するボディから効果音が放射される。
本発明の第2の実施の形態では、第1の実施の形態に対し、電力制御部220の内部構成が異なる。従って、図3、図4に代えて図6(b)を用いて本実施の形態を説明する。図6(b)は、電力制御部220のハード構成のブロック図である。電力制御部220は、DC−DCコンバータ222に代えてDC−DCコンバータ230を有する。図1において、DC−DCコンバータ222をDC−DCコンバータ230に置き換えるものとする。その他の構成は第1の実施の形態と同様である。
