Title (EN) SOUND REPRODUCING APPARATUS
(FR) APPAREIL DE REPRODUCTION DE SON
(JA) 音響再生装置
Abstract: front page image
(EN)A sound reproducing apparatus uses, as a carrier frequency, a frequency in a part of a frequency band in which mode-coupled vibrations can be excited.  A frequency of mode coupling, which exhibits a low change rate of vibration displacement relative to frequency, is used as a carrier signal, thereby allowing signals of an audible band outputted from a source of audible band signals to be demodulated and reproduced at a sound pressure that is stable in a wide frequency band.
(FR)
(JA)本発明の音響再生装置は、モード結合した振動を励振することができる周波数帯域の一部を搬送波の周波数とする。周波数に対する振動変位の変化率の低いモード結合の周波数を搬送信号とすることで、可聴帯域信号源から出力された可聴帯域の信号を幅広い周波数帯域で安定した音圧にて復調、再生可能とする。
