manner even in a car, and not only car stereo speakers are installed on the left and right two
places of the rear tray provided behind the rear seat but also instrument panels The multispeaker is being developed, such as being attached to both sides of the In addition, the
performance of a genuine speaker specified by a car manufacturer is not enough, and
replacement of a genuine speaker installed in a rear tray portion is performed according to one's
preference. Also, in the case of a hatchback type automobile, when the speakers are attached
only to both sides of the instrument panel, the speakers are added to the left and right two places
of the rear tray.
[0003]
However, as shown in FIG. 3, the rear tray 1 provided behind the rear seat S of a recent
automobile has a step 2 to improve the design and usability. The groove 3 is often provided, and

and there is a problem that the speaker can not be attached well. This problem will be described
in more detail with reference to FIGS. 4 to 6.
[0004]
FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b) show an example of the rear tray 1 provided with
the groove portion 3 having the conventional level difference 2, and FIG. 4 (a) and FIG. 5 (a) is a
plan view of the rear tray 1, FIG. 4 (b) is a local sectional view taken along the line A-A of (a), and
FIG. 5 (b) is a local sectional view taken along the B-B line of (a) It is. In the example of FIG. 4, a
circular speaker attachment hole 4 is provided in the groove 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, at the end of the groove portion of the rear tray 1, the speaker mounting hole 5 which
reaches the step 2 is provided. If such speaker mounting holes 4 and 5 are provided in the
groove portion 3, the attachable speaker is restricted by the size of the step 2 and the groove
portion 3 and it becomes difficult to attach a favorite one . For example, in the rear tray 1
provided with the speaker mounting holes 4 as shown in FIG. 6, only those in which the baffle
plates 8 to which the speakers 6, 7 are attached can be inserted into the groove portion 3 of the
rear tray 1 can be attached. Further, depending on the mounting method, there is a possibility
that the baffle plate 8 and the step 2 may hit at the C and D parts in the figure.
[0005]
Therefore, the present invention solves the problem that the types of speakers that can be
attached when such a rear tray has a step is limited, and various speakers can be attached to the
rear tray without a step taken into consideration. Is intended to provide a speaker mounting
structure that can
[0006]
In order to achieve the above object, according to the speaker mounting structure of the present
invention, the speaker is mounted on a stepped rear tray provided on the rear side of a rear seat
of a car, comprising at least one speaker mounting structure. A hole for mounting a speaker is
bored, and a baffle plate to which the speaker is mounted is provided at the lower part of this
hole, a part of the edge is placed on the step upper part of the step of the rear tray, and the step
of the rear tray of the baffle plate The portion opposite to the lower portion of the step is
supported by a height adjustable positioning member provided on at least one of the lower
surfaces of the baffle plate, and the exposed portion between the baffle plate and the lower
portion of the step of the rear tray is An elastic sound insulation member is inserted in a
10-05-2019

compressed state.
[0007]
According to the speaker mounting structure of the present invention, a part of the edge portion
of the baffle plate to which the speaker is attached 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 to a predetermined
place on the lower surface.
Further, since the gap between the baffle plate and the groove portion is shielded by the elastic
sound insulating member, the sound on the rear surface of the speaker does not leak into the
vehicle compartment.
[0008]
Embodiments of the present invention will be described in detail with reference to the
accompanying drawings.
FIG. 1 is an assembled perspective view showing the construction of an embodiment of a speaker
mounting structure 10 according to the present invention, where the same reference numerals
are given to parts of the same automobile as in the prior art. Therefore, in FIG. 1, reference
numeral 1 denotes a rear tray provided behind the rear seat, 2 denotes a step, and 3 denotes a
groove lowered by one step due to the step 2. The groove 3 is provided with a speaker mounting
hole 5 extending to the step 2.
[0009]
In such a rear tray 1, in the present invention, when the size of the baffle plate 11 in which the
holes 12 and 13 for attaching the speakers are formed is larger than the dimension of the groove
3 of the rear tray 1, the groove 3 of the baffle plate 11 is A baffle plate 11 of any size can be
mounted on the rear tray 1 by placing the protruding portion on the upper side of the step 2.
That is, as shown in the embodiment of FIG. 1, when the baffle plate 11 is long in the longitudinal
10-05-2019

direction of the groove portion 3, the portion protruding from the groove portion 3 is placed on
the rear tray 1 at a portion F indicated by a two-dot chain line.
[0010]
The height adjustment screw, which is a positioning member of the baffle plate 11, is provided at
a predetermined position of the portion of the baffle plate 11 located in the groove portion 3, for
example, the lower surface of the portion of the baffle plate 11 opposite to the portion placed on
the rear tray 1. Attach 14 and adjust the height of the height adjustment screw 14 to the height
of the step 2. A cap 15 made of a flexible member is attached to the tip of the height adjusting
screw 14 to soften the contact with the groove 3 when the baffle plate 11 is pulled from the
lower side of the rear tray 1 (details will be described later) . As a result, the baffle plate 11 is in
the same state as mounted on the rear tray 1.
[0011]
Furthermore, in this embodiment, when the baffle plate 11 is supported by the height adjustment
screw 14 and the F portion of the rear tray 1, the space on the lower surface of the baffle plate
11 does not communicate with the vehicle interior of the vehicle via the groove 3. That is, the
gap between the baffle plate 11 and the groove portion 3 is made of an elastic member, for
example, a urethane-based synthetic resin so that the sound of the back of the speaker attached
to the baffle plate 11 does not leak into the vehicle compartment. The sound insulation member
16 is inserted. When the step 2 is large, two sets of the sound insulation members 16 are used in
layers. The sound insulating member 16 contracts when the baffle plate 11 is pulled from the
lower side of the rear tray 1, so that the space under the baffle plate 11 and the passenger
compartment space can be shielded without sound leakage. Further, even when the rear tray 1
has an inclination with respect to the front-rear direction as described with reference to FIG. 4,
the inclination angle θ is about 5 to 10 ° at most, so that the elasticity of the sound insulation
member 16 can be absorbed.
[0012]
FIG. 2 is a cross-sectional view of the vicinity of the speaker mounting hole 5 of the rear tray 1
showing a state in which the speakers 6 are actually attached to the speaker mounting structure
10 shown in FIG. As described above, one end of the baffle plate 11 is placed on a part of the
10-05-2019

rear tray 1, and the other end is supported by the height adjusting screw 14 with the cap 15
attached to the end. A sound insulating member 16 has a height higher than the height of the
step 2 attached in a compressed state between the baffle plate 11 and the groove 3. In addition,
the iron plate 21 for attaching a speaker is prepared beforehand under the rear tray 1 of an
actual motor vehicle, and the bracket 17 is attached to the lower surface of the baffle plate 11 to
which the speaker 6 was attached. The lower end portion of the bracket 17 is attached to the
iron plate 21 by the attachment screw 18, the stopper 19, and the retaining plate 20. In the
example of FIG. 2, the fastener 19 is a thumb screw, and turning the knob 19 pulls the bracket
17 downward and compresses the sound insulation member 16, thereby securing the bracket 11
to which the speaker 6 is attached to the rear tray 1. It is supposed to be
[0013]
With the speaker mounting structure as described above, there is no need to restrict the design
of the rear speaker coming from the mounting method and the speaker mounting process on the
vehicle side no matter how the shape of the rear tray of the car developed in the future changes.
[0014]
As described above, according to the present invention, various speakers can be attached to a
rear tray having a step without considering the step.
