A speaker disposition structure of a vehicle comprises a left hinge pillar and a right hinge pillar both extending in a vehicle up-down direction; a speaker box fixed to a lower portion of one of the left and right hinge pillars, and the speaker box having a closed inner space; and a partition located on a vehicle width direction inner side of the speaker box. A port opening connects with the inner space of the speaker box and is located in a front face of the speaker box. A space portion is surrounded by the front face of the speaker box, the dash panel, the hinge pillar, and the partition. The space portion connects with an occupant space of the space portion. A length of the space portion, from the port opening in a front-rear direction of the vehicle, is greater than a maximum length of the port opening.

Speaker disposition structure of vehicle

A speaker disposition structure comprises a hinge pillar extending in a vehicle up-down direction; a side sill extending in a vehicle front-rear direction; a speaker box fixed to the hinge pillar; and a gap portion for arranging a vehicle component at an upper part of a vehicle-interior side of the side sill. The speaker box includes an abutting part abutting the hinge pillar; an upper space portion that bulges inward in a vehicle width direction from the abutting part above the gap portion and that holds a speaker; and an extended space portion that extends downward from the upper space portion and is adjacent to a vehicle-width-direction inner side of the gap portion. A dimension in a cross section orthogonal to the vehicle front-rear direction is smaller in a lower portion of the extended space portion than in an upper portion of the extended space portion.
