| description | To provide an "audio system and on-vehicle system" capable of effectively suppressing a sound leakage to an outside of a vehicle by a comparatively simple configuration.SOLUTION: A sound X1(f) output by an i-th audio source apparatus ASi is adjusted by a frequency transmission function Wii(f) which is set in a sound leakage reduction filter Wi by an i-th sound leakage reduction filter Wi, so as to be output from an i-th speaker SPKi to a user Pi. In the sound leakage reduction filter Wi, the frequency transmission function Wii(f) is set so as to allow a sound to be comparatively smaller in the case of a frequency where a gain from the SPKi to one or more predetermined sound leakage reference positions tends to be comparatively larger compared with the gain of the frequency transmission function from the SPKi to the user Pi, and to allow the sound to be comparatively louder in the case of a frequency where a gain tends to be comparatively smaller.SELECTED DRAWING: Figure 1
【課題】比較的簡易な構成によって車外への音漏れを効果的に抑制できる「オーディオシステム及び車載システム」を提供する。【解決手段】ｉ番目のオーディオソース機器ＡＳｉが出力した音Ｘ１（ｆ）は、ｉ番目の音漏低減フィルタＷiで、音漏低減フィルタＷiに設定されている周波数伝達関数Ｗii（ｆ）で調整され、ｉ番目のスピーカＳＰＫｉからユーザＰｉに向けて出力される。音漏低減フィルタＷｉには、ＳＰＫｉからユーザＰｉまでの周波数伝達関数のゲインに比べて、ＳＰＫｉから車外の１または複数の所定の音漏れ参照位置までのゲインが比較的に大きい傾向がある周波数では音を比較的に小さくし、比較的に小さい傾向がある周波数では音を比較的に大きくする周波数伝達関数Ｗii（ｆ）を設定する。【選択図】図１ |
