DESCRIPTION JPH0725696
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
on-vehicle speaker used in a vehicle, and more particularly to an on-vehicle speaker having an
excellent mounting structure.
[0002]
2. Description of the Related Art Conventionally, when a car-mounted speaker is mounted on a
vehicle body, the car has been firmly mounted using screws, mounting brackets or the like in
order to cope with shocks caused by traveling of the car. In addition, there is a vehicle-mounted
speaker having a one-touch type mounting structure for improving productivity.
[0003]
FIGS. 4A and 4B are a front view and a side view of a speaker using a conventional elastic hook.
Insert the elastic hook 15 provided on the outer periphery of the speaker frame 2 of the speaker
unit 1 into the mounting hole (not shown) of the mounting board of the speaker and fix it.

However, in order to attach an on-vehicle speaker to a vehicle body by using a conventional
screw, a mounting bracket or the like, it takes time and labor in the mounting work at the
mounting site, and the productivity is bad. In addition, in the mounting structure for mounting
the one-touch type car-mounted speaker to the vehicle body, there is a problem that the strength
of the elastic hook for mounting by one-touch is insufficient and the elastic hook is broken. That
is, since the weight of the on-vehicle speaker rests on the elastic hook 15, there is a risk that the
elastic hook 15 may be broken or the on-vehicle speaker may be detached if the on-vehicle
speaker is heavy.
[0005]
The present invention has been made in view of such a point, and an on-vehicle mounting
structure having a structure in which an elastic hook for attaching an on-vehicle speaker to a
vehicle body by a one-touch method does not break or the like is provided. It aims at providing a
speaker for.
[0006]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, in the onvehicle speaker according to the present invention, in the on-vehicle speaker having a plurality of
attachment structures for attaching a speaker unit to a vehicle body, the attachment structure
has a cross section. Is composed of a projecting positioning portion having a concave shape and
an elastic hook portion for mounting the speaker unit, the positioning portion is provided on the
outer peripheral portion of the resin frame of the speaker unit for positioning, and the elastic
hook portion is It is characterized in that it is integrally formed at the concave position of the
positioning part.
[0007]
In another in-vehicle loudspeaker according to the present invention, in the in-vehicle
loudspeaker having a plurality of attachment structures for attaching the speaker unit to the
vehicle body, a part of the attachment structure has a concave shape in cross section. It consists
of an elastic hook for mounting the speaker unit and the speaker unit, and the other part of the
mounting structure is a hooking structure. The positioning part and hooking structure is the
outer periphery of the resin frame of the speaker unit for positioning. The elastic hook portion is
provided on a portion, and the elastic hook portion is integrally formed at a concave position of
the positioning portion.

Furthermore, in another in-vehicle speaker according to the present invention, in the in-vehicle
speaker having a plurality of attachment structures for attaching the speaker unit to the vehicle
body, the attachment structure has a projecting positioning portion having a concave shape in
cross section The positioning part is provided on the outer peripheral part of the resin frame of
the speaker unit for positioning, and the elastic hook part is different in color and material from
the positioning part, and Characterized in that it is integrally formed at a concave position of the
positioning portion
[0009]
The present invention relates to an on-vehicle speaker having a speaker mounting structure
attached to a vehicle body by a snap-in method.
An attachment structure in which the positioning protrusion and the elastic hook are integrated
is provided on the frame outer peripheral portion of the in-vehicle speaker, and the positioning
protrusion can be attached in a single shape by making it concave. Also, the strength of the
elastic hook is improved. can do.
That is, the speaker mounting structure integrally forms an elastic hook portion and a positioning
portion which is a U-shaped protrusion surrounding the periphery thereof, and the positioning is
facilitated and mechanical reinforcement is achieved by this U-shaped protrusion. .
[0010]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present
invention will be described below with reference to the drawings.
FIG. 3 is an explanatory view of a mounting structure used for the on-vehicle speaker according
to the present invention.
(A) is a perspective view of the mounting structure, and (B) is a cross-sectional view. In the
drawing, in the mounting structure 3, the positioning portion 11 and the elastic hook portion 12
are integrally formed on the outer peripheral portion of the speaker frame 2. The mounting

structure integrally forms the elastic hook portion 12 and the positioning portion 11 which is a
U-shaped projection surrounding the periphery thereof, and the projection having a U-shaped
cross section facilitates positioning and mechanical reinforcement.
[0011]
FIG. 1 shows the outer shape and mounting board of a vehicle-mounted speaker in a first
embodiment of the present invention. (A) is a front view of the in-vehicle speaker, (B) is a side
view of the in-vehicle speaker, and (C) is a diagram of a mounting board for attaching the invehicle speaker. In the figure, the mounting structure 3 is provided on the outer peripheral
portion of the speaker frame 2 of the speaker unit 1 which is a vehicle-mounted speaker. Since
the mounting structure 3 is integrally formed with the elastic hook portion 12 and the
positioning portion 11 which is a U-shaped protrusion surrounding the periphery thereof, the
mounting portion 3 of the mounting structure 3 of the speaker unit 1 is mounted on a mounting
board The elastic hook portion 12 of the mounting structure 3 is fixed by one-touch insertion
into the mounting hole 6 provided in the vicinity of the speaker mounting hole 6 of FIG.
[0012]
FIG. 2 shows the outer shape and mounting board of a vehicle-mounted speaker in a second
embodiment of the present invention. (A) is a front view of the in-vehicle speaker, (B) is a side
view of the in-vehicle speaker, and (C) is a diagram of a mounting board for attaching the invehicle speaker. In the drawing, the hooking portion 4 is hooked to the mounting hole 7 provided
in the vicinity of the speaker mounting hole 6, and the positioning portion 11 of the other
mounting structure 3 is mounted in the vicinity of the speaker mounting hole 6 of the mounting
board 8. The elastic hook portion 12 of the mounting structure 3 is fixed by being inserted into
the hole 6 with one touch.
[0013]
Next, a third embodiment of the present invention will be described. In the mounting structure 3
of FIG. 3 described above, the performance of the mounting structure 3 is further improved by
two-color molding using different materials in which the elastic hook portion 12 is made of resin
having high elasticity and the positioning portion 11 is made of resin having high rigidity. Can.
Therefore, the in-vehicle speaker can be fixed easily and stably, and the mounting reliability is

also improved.
[0014]
As described above, in the vehicle-mounted speaker according to the present invention, the
mounting structure includes a projecting positioning portion having a concave cross section and
an elastic hook portion for mounting the speaker unit. The protruding portion is provided on the
outer periphery of the resin frame of the speaker unit for positioning, and the elastic hook
portion is integrally formed at the concave position of the positioning portion, so that the
strength of the elastic hook can be improved. The positioning can be facilitated and mechanical
reinforcement can be achieved.
