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.

To a hinge pillar including a hinge pillar inner and a hinge pillar outer that form a closed cross-section extending vertically, a speaker box configured to hold and house a speaker therein is joined and fixed. As necessary, the speaker box includes a box part formed of a sheet metal member including a bottom and side walls that form a housing space housing the speaker, together with the bottom. The box part is arranged in the opening, with the bottom located in the closed cross-section and with the housing space open inside a vehicle cabin, and is joined to an edge of the opening.

Vehicle speaker disposition structure

A sound system for a vehicle driven by an engine is provide, which includes an audio device for an internal space of a cabin of the vehicle, and a traveling state determiner configured to determine a traveling state of the vehicle. The audio device is configured to change a quality of a sound reproduced by a sound source and, when the traveling state determined by the traveling state determiner is a given traveling state, degrade the quality of the reproduced sound.

Sound system for vehicle

A sound system for a vehicle including an engine and an audio device for an internal space of a cabin as sound sources disposed at given positions of the vehicle is provided. The audio device is switchable between a first mode in which an audio sound including both an audible sound and an inaudible sound for a human is reproduced in the cabin and a second mode in which an audio sound including the audible sound but not including the inaudible sound is reproduced in the cabin. The sound system includes a traveling state detector configured to detect a traveling state of the vehicle, and a switch controlling module executable by a processor configured to reproduce the audio sound in the first mode under a condition that a given traveling state is detected by the traveling state detector.
