2. Description of the Related Art In recent years, there has been a demand for listening to music in a car with a realistic feeling, and speakers for car stereos are not only installed at two places on the left and right of a rear tray provided behind a rear seat, but also an instrument panel. Multi-speakers are being installed, such as being attached to both side parts of the. In addition, the performance of the genuine speaker specified by the automobile manufacturer is not enough, and the genuine speaker installed in the rear tray part is replaced with one's own preference. Further, in the case of a hatchback type automobile, even when the speakers are attached only to both side portions of the instrument panel, the speakers are added to two places on the left and right of the rear tray.

[0003]

However, as shown in FIG. 3, the rear tray 1 provided on the rear side of the rear seat S of a recent automobile has a step 2 in order to improve design and usability. Grooves 3 are often provided, and when a speaker is attached to such a rear tray 1 later, there is a problem that the step 2 becomes an obstacle and the speaker cannot be attached properly. This problem will be described in more detail with reference to FIGS.

FIGS. 4 (a), 4 (b) and 5 (a), 5 (b) show an example of a conventional rear tray 1 provided with a groove portion 3 having a step 2, and FIG. ), Fig. 5 (a) shows the rear tray 1
4B is a local sectional view taken along the line AA of FIG. 4A, and FIG. 5B is a local sectional view taken along the line BB of FIG. In the example of FIG. 4, a circular speaker mounting hole 4 is provided in the groove portion 3 of the rear tray 1, and the surface of the rear tray 1 is inclined at an angle θ in the rear seat direction. Further, in the example of FIG. 5, the speaker mounting hole 5 reaching the step 2 is provided at the end of the groove of the rear tray 1. If such speaker mounting holes 4 and 5 are provided in the groove portion 3, the speaker that can be mounted is restricted by the size of the step 2 and the groove portion 3, and it becomes difficult to mount a desired speaker. .. For example, in the rear tray 1 having the speaker mounting holes 4 as shown in FIG.
Therefore, only the baffle plate 8 to which the baffle plate 8 attached can fit in the groove portion 3 of the rear tray 1 can be attached.
Further, depending on how to attach, the baffle plate 8 and the step 2 may hit each other in the portions C and D in the drawing.

Therefore, the present invention solves the problem that the types of speakers that can be mounted are limited when the rear tray has a step, and various speakers can be installed in the stepped rear tray without considering the step. It is an object of the present invention to provide a speaker mounting structure capable of mounting a speaker.

[0006]

The speaker mounting structure of the present invention for achieving the above object is a structure for mounting a speaker on a stepped rear tray provided on the rear side of a rear seat of an automobile, and at least one speaker mounting structure is provided. A speaker mounting hole is bored, and a baffle plate on which a speaker is mounted is placed in the lower part of the hole, and a part of the edge of the baffle plate is placed on the upper step of the step of the rear tray. The portion of the baffle plate facing the step lower portion is supported by a height-adjustable positioning member provided at at least one position on the lower surface of the baffle plate, and the exposed portion between the baffle plate and the step lower portion of the step of the rear tray is The elastic sound insulating member is inserted in a compressed state.

[0007]

According to the speaker mounting structure of the present invention, a part of the edge portion of the baffle plate on which the speaker is mounted is supported on the step upper part of the step of the rear tray, and the portion facing the groove portion of the baffle plate is the baffle plate. It is supported by a height-adjustable positioning member attached at a predetermined position on the lower surface. Since the gap between the baffle plate and the groove is shielded by the elastic sound insulation member, the sound on the back surface of the speaker does not leak into the vehicle interior.
