To suppress a driver's excessive behavior due to an oriented sound image when a stereoscopic sound image reproduction system is used for a vehicle.SOLUTION: A stereoscopic sound image reproduction system for vehicles comprises: a sound reproduction device having a sound image generation unit; and a vehicle sensor capable of detecting the face or line of sight of the driver of a vehicle or the traveling direction of the vehicle. The sound reproduction device sets an orientation-permitted angle scope, using the direction of the driver or the vehicle as a reference direction, before starting the generation of a sound image relative to a sound source by the sound image generation unit, and determines whether the direction of the original orientation of the sound image is within the orientation-permitted angle scope. If it is within the orientation-permitted angle scope, the sound reproduction device starts generation of the sound image at the original orientation. If not, the sound reproduction device does not start generation of the sound image at the original orientation.SELECTED DRAWING: Figure 3

    【課題】立体音像再生システムを、車両に用いる場合での、定位する音像に起因するドライバの過度な挙動を抑制する。【解決手段】車両の立体音像再生システムは、音像生成部を有する音再生装置と、車両のドライバの顔若しくは視線または車両の進行方向を検出可能な車両センサと、を有する。音再生装置は、音像生成部による、音源についての音像の生成を開始する前に、ドライバまたは自動車の向きを基準方向として定位許可角度範囲を設定し、音像のオリジナルの定位の方向が定位許可角度範囲の以内であるか否かを判断する。定位許可角度範囲の以内である場合、音再生装置は、音像をオリジナルの定位で生成することを開始する。定位許可角度範囲の以内でない場合、音再生装置は、音像をオリジナルの定位で生成することを開始しない。【選択図】図3
