A speaker 20 arranged in the internal space C1 is provided as a main configuration.

  As shown in FIG. 2, the quarter panel 110 is adjacent to a door opening C2 closed by the rear door 120b and an opening C3 where a wheel house (not shown) is arranged. Further, as shown in FIG. 3, a quarter inner reinforcement 111 and a quarter outer reinforcement 112 that reinforce the quarter panel 110 are disposed in the internal space C1, and an interface that regulates the reclining operation of the seat in the passenger compartment. A part of the anchorage 40 for detachably fixing the lock mechanism 30 and the seat belt is accommodated. In FIG. 2, only the outline of the quarter panel outer 110a is indicated by a broken line.

  In the quarter panel 110, the quarter inner reinforcement 111 and the quarter outer reinforcement 112 are disposed so as to protrude toward the passenger compartment. Further, the main surface of the quarter panel outer 110a on the outside of the vehicle is substantially parallel to the vehicle length direction S indicated by the alternate long and short dash line in the figure, while the quarter panel inner 110b on the passenger compartment side includes the quarter inner reinforcement 111 and the quarter outer. Starting from the vicinity of the reinforcement 112, it is formed as an inclined surface having an opening angle θ toward the outside of the vehicle.

  As a result, the interior of the vehicle 100 has a cargo compartment formed from the quarter panel 110 to the back door 130 with respect to the passenger compartment having the front door 120a and the rear door 120b parallel to the vehicle length direction S as side walls. The width dimension, that is, the dimension in the direction perpendicular to the vehicle length direction S is expanded. In the cargo compartment, a lining 113 parallel to the quarter panel inner 110b is provided, and this lining 113 forms the inner wall surface of the cargo compartment. In FIG. 3, the lining 113 shows only the cross section of the main surface by a broken line.

  Next, the speaker 20 is mounted on a planar annular bracket 23, and the bracket 23 is fixed to the quarter panel 110 by being screwed to the quarter panel inner 110b with a mounting screw 23a. In the speaker 20, a speaker unit 21 including a voice coil, a magnet, a cone, and the like is disposed in the internal space C1, and the cone main surface 22 and the speaker grille 24 are exposed from a recess C1x provided on the surface of the quarter panel inner 110b. Then, it faces the lining 113.

  In the above configuration, the speaker arrangement structure 1 corresponds to the speaker arrangement structure of the present invention, the speaker 20 corresponds to the speaker of the present invention, and the quarter panel inner 110b corresponds to the quarter panel inner of the present invention.
