To provide an audio system for vehicles with which it is possible to realize intended auditory localization.SOLUTION: The audio system for vehicles includes: a tweeter 14 for driver's seat right, which is arranged facing the driver's seat on the front right side of a driver's seat; a tweeter 16 for driver's seat left, which is arranged facing the driver's seat on the front left side of the driver's seat and the directivity of which is narrower than the tweeter 14 for the driver's seat right; a tweeter 18 for passenger seat right, which is arranged facing a passenger seat on the front right side of the driver's seat and to the left of the tweeter 14 for driver's seat right; a tweeter 20 for passenger seat left, which is arranged facing the passenger seat on the front left side of the passenger seat and to the left of the tweeter 16 for driver's seat left, and the directivity of which is narrower than the tweeter 18 for the passenger seat right; and a delay processing unit 28 for causing a sound signal outputted to the tweeter 14 for driver's seat right to be delayed behind the tweeter 16 for driver's seat left and causing a sound signal outputted to the tweeter 20 for passenger seat left to be delayed behind a sound signal outputted to the tweeter 18 for passenger seat right.SELECTED DRAWING: Figure 3
【課題】狙った音像定位を実現可能な車両用オーディオシステムを提供することを目的とする。【解決手段】運転席の前方右側に運転席に向けて配置された運転席右用ツィーター14と、運転席の前方左側に運転席に向けて配置され、かつ運転席右用ツィーター14よりも狭指向性とされた運転席左用ツィーター16と、運転席の前方右側でかつ運転席右用ツィーター14の左側に助手席に向けて配置された助手席右用ツィーター18と、助手席の前方左側でかつ運転席左用ツィーター16の左側に助手席に向けて配置され、かつ助手席右用ツィーター18よりも狭指向性とされた助手席左用ツィーター20と、運転席右用ツィーター14に出力する音声信号を運転席左用ツィーター16より遅延させ、助手席左用ツィーター20に出力する音声信号を助手席右用ツィーター18へ出力する音声信号より遅延する遅延処理部28と、を含む。【選択図】図3
