To provide an acoustic system capable of flexibly setting a position of a microphone and reducing howling with a simple mechanism.SOLUTION: An acoustic system to be used in a cabin R of an automobile comprises: a plurality of speakers including the first speaker; and a microphone 11 arranged inside the cabin R so as to output an output signal based on collected voice. A first input signal including a first sub-signal corresponding to the output signal is input to the first speaker 21. A distance between the first speaker 21 and the microphone 11 is shorter than a distance between the other speaker other than the first speaker 21 included in the plurality of speakers and the microphone 11. A distance between the first speaker 21 and a headrest 51-1 included in a seat arranged inside the cabin R is shorter than a distance between the other speaker and the headrest 51-1.SELECTED DRAWING: Figure 3

    【課題】マイクの位置をフレキシブルに設定すること、及び簡便な機構でハウリングを低減することが可能な音響システムを提供する。【解決手段】自動車の車室Rで用いられる音響システムであって、第1スピーカーを含む複数のスピーカーと、車室R内に設置され、収音した音に基づいて出力信号を出力するマイク11とを備え、第1スピーカー21に、出力信号に応じた第1サブ信号を含む第1入力信号が入力され、第1スピーカー21とマイク11との距離は、複数のスピーカーに含まれる第1スピーカー21以外の他のスピーカーとマイク11との距離よりも短く、第1スピーカー21と、車室R内に設置されるシートに備わるヘッドレスト51-1との距離は、他のスピーカーとヘッドレスト51-1との距離よりも短い。【選択図】図3
