To specify the orientation of a sound source in a cabin, and reproduce the sound field in such a manner that sound is actually produced from the orientation.SOLUTION: An acoustic device according to an embodiment includes a microphone, a plurality of first speakers, a second speaker, a voice acquisition unit, and an output control unit. The plurality of first speakers are provided at height positions that are visible in a state where a passenger in the cabin faces the front. The second speaker is provided below the first speakers. The voice acquisition unit acquires voice produced by a sound source and collected by the microphone. The output control unit outputs the voice acquired by the voice acquisition unit through a first speaker in the vicinity of the sound source in reverse phase, and outputs the voice acquired by the voice acquisition unit through the remaining first speakers and the second speaker.SELECTED DRAWING: Figure 2

    【課題】車室において、音源の方位を特定し、その方位から実際に音がしているように音場を再現すること。【解決手段】実施形態に係る音響装置は、マイクと、複数の第1のスピーカと、第2のスピーカと、音声取得部と、出力制御部とを備える。複数の第1のスピーカは、車室内の搭乗者が前方を向いた状態で視認可能となる高さ位置に設けられる。第2のスピーカは、第1のスピーカよりも下方に設けられる。音声取得部は、音源から発生してマイクによって集音された音声を取得する。出力制御部は、音声取得部によって取得された音声を音源の近傍の第1のスピーカから逆位相出力するとともに、残りの第1のスピーカおよび第2のスピーカからは前記音声取得部によって取得された音声を出力する。【選択図】図2
