DESCRIPTION JP2002218580
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker mounting structure, and more particularly to a speaker mounting structure suitable for a
vehicle-mounted speaker.
[0002]
2. Description of the Related Art An example of a conventional on-vehicle speaker mounting
structure is shown in FIG. The tweeter main body 6 shown in FIG. 5 is connected with the case
member 7 (tightening with a screw or fitting of the uneven portion). A spherical portion 9a
provided at the tip of the support 9b of the stand 9 is accommodated inside the case member 7,
and the case 9 and a plate spring member 8 fitted to the case member 7 hold the spherical
portion 9a in a resilient state Do. The stand 9 is formed of two pieces.
[0003]
That is, the tweeter body 6 is rotatably supported on the stand 9. By mounting the stand 9 on a
rear tray or the like, the tweeter main body 6 can be attached to the vehicle so as to be
changeable.

Another example of the conventional on-vehicle speaker mounting structure is shown in FIG. The
convex portion 11 a of the plate spring member 11 can be fitted in the concave portion 10 a of
the tweeter main body 10 shown in FIG. The tweeter main body 10 can be attached to the vehicle
by tightening the screws 5, 5 inserted through the screw insertion holes 11b of the plate spring
member 11 to the vehicle interior material 12 such as a rear tray.
[0005]
SUMMARY OF THE INVENTION In the speaker mounting structure shown in FIG. 5, the mounting
method is limited to the method of mounting the stand on the rear tray or the like. In addition,
since the speaker angle adjustment range is limited by the interference between the case member
7 and the stand 9 and the interference between the case member 7 and the floor on which the
stand member 9 is mounted, it is difficult to set the speaker angle adjustment range optimally.
there were.
[0006]
In the mounting structure of the speaker shown in FIG. 6 described above, the mounting method
is limited to the method of mounting the speaker in a fixed state, and the posture of the speaker
can not be adjusted.
[0007]
The present invention has been made in view of the above-described point, and an object of the
present invention is to provide a speaker mounting structure capable of selecting a speaker
mounting method as either a fixed or pivotable method. .
[0008]
Furthermore, an object of the present invention is to provide a speaker mounting structure in
which the setting of the pivotable range when the speaker is rotatably mounted can be easily
performed.
[0009]
According to the speaker mounting structure of the present invention, the leaf spring member

fitted to the speaker main body is provided with a spherical recess and a screw insertion hole,
and the speaker main body is formed by the screw inserted through the screw insertion hole. It is
possible to fasten to a floor or a wall surface, and further, the spherical recess provided on the
top of the stand by the spherical recess of the plate spring member and the case member is
pinched in a state of elastic rotation to form a coupled pair. It is possible to rotatably support the
speaker body by the stand.
[0010]
Further, in the speaker mounting structure, the spherical portion provided on the top of the
stand is provided with a protrusion for restricting the rotation range of the speaker main body.
[0011]
Furthermore, in each of the speaker mounting structures, the speaker is a vehicle-mounted
speaker.
[0012]
DESCRIPTION OF THE PREFERRED EMBODIMENTS A speaker mounting structure which is an
embodiment of the present invention will be described based on the drawings.
FIG. 1 is an exploded sectional view showing a speaker mounting structure according to an
embodiment of the present invention, and FIG. 2 is a sectional view showing the speaker
mounting structure.
[0013]
The tweeter main body 1 shown in FIG. 1 and FIG. 2 is provided with recesses 1a, 1a, and the
plate spring member 4 is a tweeter by fitting the protrusions 4a, 4a of the plate spring member 4
into the recesses 1a, 1a. It is fitted to the main body 1.
[0014]
The plate spring member 4 is provided with screw insertion holes 4b, 4b, and the tweeter main
body 1 is made by screwing the screws 5, 5 inserted through the insertion holes 4b, 4b into the
vehicle interior material as in the conventional example. It can be fixed to the interior material.

[0015]
The plate spring member 4 can be fastened to the case member 2 by screwing the screws 5, 5
through which the plate spring member 4 is inserted into the bosses 2b, 2b of the case member
2 as shown in FIG.
However, in FIG. 2, illustration of the screws 5 and 5 and the bosses 2b and 2b is omitted.
[0016]
When fastening the plate spring member 4 to the case member 2, as shown in FIG. 2, the support
3c of the stand 3 is inserted through the slit 2c of the case member 2 and the spherical portion
3a provided on the top of the support 3c is The tweeter main body 1 can be rotatably supported
by the stand 3 while the elastic force is applied by the boss 2 a of the case member 2 and the
plate spring member 4.
[0017]
At this time, the boss 2a and the plate spring member 4 are provided with a spherical recess that
matches the spherical surface of the spherical portion 3a so that the spherical portion 3a and the
boss 2a of the case member 2 and the plate spring member 4 turn reliably. There is.
[0018]
In order to regulate the rotation range of the tweeter main body 1 with respect to the stand 3,
protrusions 3b, 3b are provided on the spherical portion 3a.
Therefore, as shown in FIG. 3, the case member 2 can be rotated in the horizontal direction from
the center position by an angle of α.
Further, as shown in FIG. 4, the case member 2 can be inclined from the horizontal side by an
angle of β by the contact between the support 3 c of the stand 3 and the end of the slit 2 c.

In this manner, the pivoting range of the tweeter main body 1 can be clearly regulated.
[0019]
According to the speaker mounting structure of the present invention, it is possible to use
common parts for mounting the speaker in a fixed state and for mounting it rotatably.
And when it mounts rotatably, the rotation range can be defined clearly.
