Zusammenfassung:To optimize the volume of sound played in an audio spot.SOLUTION: A parametric speaker device D includes a control terminal T, one or more carrier wave speakers C, one or more sideband wave speakers S, and a speaker arrangement portion 10, and the control terminal T is communicably connected to one or more carrier wave speakers C and one or more sideband wave speakers S, and one or more carrier wave speakers C and one or more sideband wave speakers S are arranged in the speaker arrangement portion 10, the control terminal T divides sound into a carrier wave and a sideband wave, calculates the division frequency at which the sum of the amplitude spectra of each sideband wave becomes equal, and the sideband wave is divided according to the calculated division frequency, and the divided sideband waves are radiated from each of the one or more sideband wave speakers S.SELECTED DRAWING: Figure 1 【課題】オーディオスポット内で再生される音の音量を最適化する。【解決手段】パラメトリックスピーカ装置Dは、制御用端末Tと、1以上のキャリア波スピーカCと、1以上の側帯波スピーカSと、スピーカ配設部10とを備え、制御用端末Tは、1以上のキャリア波スピーカC及び1以上の側帯波スピーカSと通信可能に接続され、スピーカ配設部10には1以上のキャリア波スピーカCと1以上の側帯波スピーカSとが配置され、制御用端末Tは、音声をキャリア波と側帯波とに分割し、各側帯波の振幅スペクトルの和が等しくなる分割周波数を算出し、算出された分割周波数に応じて側帯波を分割して、分割された側帯波を1以上の側帯波スピーカSのそれぞれから放射する。【選択図】図1
