VEHICULAR SPEAKER ARRANGEMENT STRUCTURE

To provide a vehicular speaker arrangement structure which secures a capacity of a speaker box without compressing a cabin, enables creation of the layout of vehicular components below the inside of a passenger compartment of a hinge pillar, and achieves improvement of low sound reproduction efficiency by reduction of flow resistance of air in the speaker box.SOLUTION: A speaker box 40 includes: a contact section 44 which contacts with a hinge pillar 30; an upper space section S3 which expands inward in a vehicle width direction from the contact section 44 above a gap part S1 and holds a speaker 41; and an extension space section S4 extending downward from the upper space section S3 and located adjacent to the inner side as seen in the vehicle width direction of the gap part S1. The upper space section S3 and the extension space section S4 communicate in a vertical direction to form a closed space S5. The extension space section S4 is formed so that its dimension in the vehicle width direction is smaller at the lower side than at the upper side on a cross section orthogonal to a vehicle fore and aft direction.SELECTED DRAWING: Figure 5 【課題】キャビンを圧迫することなく、スピーカボックスの容量確保と、ヒンジピラー車室内側下方の車両部品のレイアウト成立と、スピーカボックス内の空気の流動抵抗低減による低音再生効率の向上と、を達成する車両のスピーカ配設構造を提供する。【解決手段】スピーカボックス４０は、ヒンジピラー３０に当接する当接部４４と、空隙部Ｓ１の上方において当接部４４から車幅方向内側に膨出しスピーカ４１を保持する上方空間部Ｓ３と、上方空間部Ｓ３から下方に延びて空隙部Ｓ１の車幅方向内側に隣接する延長空間部Ｓ４と、を備え、上方空間部Ｓ３と延長空間部Ｓ４とを上下方向に連通して閉じた空間Ｓ５を形成し、延長空間部Ｓ４は、車両前後方向に直交する断面で、車幅方向寸法が上方に対して下方が小さくなるように形成されたことを特徴とする。【選択図】図５
