[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
wiring structure of a vehicle speaker.
[0002]
2. Description of the Related Art A conventional example of a speaker wiring structure attached
to a door or the like of a vehicle will be described below with reference to FIGS.
[0003]
The connection between the speaker 30 and the wire harness 36 of the vehicle in the
conventional wiring structure of the speaker 30 is achieved by connecting the lead wire 33
whose one end is connected to the terminal 32 of the speaker 30 as shown in FIG. It penetrates
through and connects the connector 35 attached to the other end of this lead wire 33, and the
connector 37 attached to the wire harness 36 of a vehicle.
[0004]
In this case, in order to actually attach the speaker 30 to the door 40 of the vehicle, the
attachment holes 41 and the four attachment holes 42 are provided in the wall portion 40a of
the door 40 shown in FIGS. The grommet 43 is attached to 42, the speaker 30 is inserted into the
mounting hole 41, and screws are screwed from the four insertion holes 38 of the speaker 30
into the respective grommet 43, whereby the wall portion 40a of the speaker 30 is obtained. Fix

However, in the case of the above-described conventional speaker wiring structure for a vehicle,
the lead wire 33 from the terminal 32 to the connector 35 becomes an aerial wiring, and the
connection work of the connectors 35 and 37 is necessary. In order to prevent noise, it is
necessary to fix the connectors 35 and 37 to the wall 40a, and in order to prevent the water of
the lead 32 from being flooded to the terminal 32, the adhesive 32 is used to prevent the water
of the core wire. There is a problem that the wiring operation is extremely complicated, such as
the need to apply to the
[0006]
An object of the present invention is to provide a speaker wiring structure for a vehicle which
can eliminate the complicated work as in the prior art and can greatly simplify the wiring work.
[0007]
The speaker wiring structure for a vehicle according to the present invention uses a flexible
printed circuit board having one end connected to the coil of the speaker main body and the
other end drawn along the recessed groove provided in the speaker frame. Wire harness, an end
fixing tool for fixing the other end side of the lead wire at the position of the mounting hole of
the speaker frame, and the end fixing tool attached to the end of the wire harness drawn from
the vehicle And a grommet integrated terminal portion for fixing the speaker frame to a
mounting target while being in contact with the lead wire.
[0008]
The operation of the present invention will be described below.
According to this vehicle speaker wiring structure, one end is connected to the coil of the speaker
body using a lead wire using a flexible printed circuit board, and the other end is led out along
the recessed groove provided in the speaker frame The grommet integrated terminal portion
fixed at the position of the mounting hole of the speaker frame by the end fixing tool and
attached to the end of the wire harness led out from the vehicle makes the end fixing tool in
contact with the wire of the wire harness Since the speaker frame is fixed to the mounting object,
the connection between the lead wire and the wire harness can be completed at the same time as
fixing the speaker to the mounting object, and the complicated operation as in the prior art is

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the
present invention will be described below with reference to FIGS.
The wiring structure of the vehicle speaker 1 shown in FIG. 1 is a lead wire using a flexible
printed board whose one end is connected to the coil of the speaker main body 2 and the other
end is led out along the recessed groove 4 provided in the speaker frame 3 5 and the end fixing
device 7 for fixing the other end side of the lead wire 5 at the position of the mounting hole 6 of
the speaker frame 3 and the end fixing attached to the end of the wire harness 8 derived from
the vehicle A grommet integrated terminal portion 9 for fixing the tool 7 to a mounting object of
the speaker frame 3 while contacting the lead of the wire harness 8.
A seal sponge 10 is mounted around the speaker body 2 in a circular arrangement.
[0010]
As shown in FIG. 2, the speaker frame 3 is formed with a branch concave groove 4 a
corresponding to the branch portion 5 a of the lead wire 5 and a branch concave corresponding
to the boss insertion hole 5 b provided in the branch portion 5 a A positioning boss 11 is
provided in the groove 4a so as to protrude therefrom.
Then, the lead wire 5 is fixed by inserting the branch portion 5a of the lead wire 5 into the
branch concave groove 4a and inserting the positioning boss 11 into the boss insertion hole 5b.
[0011]
Further, as shown in FIGS. 2 and 3, the seal sponge 10 is applied to the inside of the branch
portion 5 a of the lead wire 5.

The end fixture 7 mounts the connection terminal 12 connected to the lead wire 5 to the
attachment hole 6 of the recessed groove 4 of the speaker frame 3 as shown in FIG. By mounting
the crimp terminal fitting 13 and performing a crimping operation, the connection terminal 12
connected to the lead wire 5 is fixed to the mounting hole 6.
[0013]
FIG. 5 shows the construction of the grommet integrated terminal portion 9, which comprises a
waterproof grommet 20 having a mounting recess 21 mounted on a door inner panel 45
constituting the wall 40a of the door 40. The grommet integrated terminal 24 is configured by
caulking the grommet caulking terminal 23 attached to the end of the wire harness 8 in the
terminal caulking notch 22 provided in the grommet 20, as shown in FIG. The grommet
integrated terminal 24 is stacked on the end fixing member 7 attached to the mounting hole 6
and screwed with a screw 25 to connect the end fixing member 7 and the wire harness 8 and the
door inner panel 45 of the speaker frame 3 It is designed to be installed at the same time.
[0014]
Next, application examples of the above-described wiring structure will be described with
reference to FIGS. 7 and 8.
First, as shown in FIG. 7, of the four attachment holes 42 provided in the door inner panel 45
constituting the wall 40a of the door 40, the grommet integrated terminal 24 is provided at two
places, and the other two places. Wear a normal grommet 43.
Next, as shown in FIG. 8, the speaker 1 is inserted into the mounting hole 41, and screws 25 are
respectively inserted into the two end fixtures 7 on the speaker frame 3 side and screwed into
the grommet integrated terminal 24.
Screws 25 are also screwed into the grommet 43 at the other two places.
[0015]
Thereby, the speaker 1 can be attached to the door inner panel 45 with extremely simple
12-04-2019

operation.
Then, the wiring work is completed simultaneously with the mounting work of the speaker 1, the
wiring of the lead wire 5 is easy, and the use of a connector is also unnecessary.
Furthermore, the application of an adhesive for waterproofing becomes unnecessary. The present
invention can be modified in various ways within the scope of the invention in addition to the
above-described embodiment.
[0016]
According to the present invention described above, it is possible to provide a wiring structure
for a vehicle speaker which eliminates the complicated work as in the prior art and can greatly
simplify the wiring work.
