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 direction of a vehicle or a driver. The sound reproduction device sets an angle scope extending in the right and left directions of the vehicle from a reference direction based on the driver or the vehicle while or before the generation of a sound image at the original orientation relative to a sound source, as an orientation-permitted angle scope. If the direction of the driver during the generation of the sound image remains within the orientation-permitted angle scope, the sound reproduction device continues the generation of the sound image at the original orientation. If the direction of the driver does not remain in the orientation-permitted angle scope, the sound reproduction device stops the generation of the sound image at the original orientation.SELECTED DRAWING: Figure 4

    【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、車両またはドライバの方向を検出可能な車両センサと、を有する。音再生装置は、音源についてのオリジナルの定位での音像の生成中または生成前での、ドライバや車両に基づく基準方向から車両の左右方向へ広がる角度範囲を定位許可角度範囲として設定する。音再生装置は、音像の生成中のドライバの方向が定位許可角度範囲の以内を維持している場合、音再生装置は、オリジナルの定位での音像の生成を継続する。ドライバの方向が定位許可角度範囲の以内を維持していない場合、音再生装置は、オリジナルの定位での音像の生成を中断する。【選択図】図4
