BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial cross-sectional view of a conventional
speaker system, FIG. 2 is a partial cross-sectional view of a speaker system according to an
embodiment of the present invention, and FIGS. Another mounting of the speaker frame is a
partial cross-sectional view of one of the speaker systems. In the figure, 1 is a baffle plate, 2 is a
sub baffle plate, 2a is a counterbore, 2b is a hole, 3 is a speaker, 5 is a flat head screw, 10 is a 4
slotted plate, 10a is a boss, 10b is a hole, 11 is a speaker frame, The reference numeral 11a
denotes a recess, 11b and 11c denote mounting holes, 12 denotes a round screw, and 13
denotes a nut.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker frame in
which a speaker can be attached from the back side to a baffle plate or a subbuckle plate of a
speaker system. FIG. 1 is a partial sectional view 5 of a conventional speaker system. -In this
figure, 1 is a baffle plate, 2 is a sub baffle plate, and countersunk screw 2a of a countersunk
screw at the time of screwing. A hole 2b is provided. Reference numeral 3 is a speaker, and 4 is a
speaker frame of the front speaker il + -1, -5-5 8 '' /. The speaker frame 4 is provided with
mounting holes 4a at positions corresponding to the holes 2b. 5 is a book screw. The mounting
hole 4 & is provided in advance with a female screw to be screwed with the device screw 5, or is
a hole in which a self-tapping can be made by the device screw 5 at the time of mounting. The
speaker system shown in FIG. 1 is fixed to the sub baffle plate 2 with a flathead screw 5 using the
speaker 3, that is, the mounting hole 4a of the speaker frame 4, and the sub baffle plate 2 is
further flat screwed to the baffle plate 1. Fix it with 5. In this fixation, the blood screw 5 is traced
from the front to the counterbore 28 provided on the sagar-full plate 2 of the speaker system,
and is screwed into the mounting hole 4a. The reason why the sub baffle plate 2 is attached from
the front is thin because it is made of a sheet metal such as aluminum, and if a screw is used
from the back face of the sub baffle plate 2, the screw will protrude to the front face of the sub
baffle & 2. As described above, conventionally, there is a limitation that the plate (2) must be

fixed with the screw (2) 5 from the front surface of the sub baffle plate 2, and there is a
disadvantage that the design freedom is not achieved. The present invention is considered in
view of the above-mentioned point, and provides a speaker frame in which a speaker that can
break on a baffle plate or a sub baffle plate can be attached with a screw from the back side.
Hereinafter, this invention will be described on the basis of drawings. FIG. 2 is a partial crosssectional view of a speaker system according to one embodiment of the present invention. In this
figure, 10 is a sub baffle plate, and the boss 10m and the hole 10b are used, and the whole is
formed by tie casting. A speaker frame 11 is provided with a recess 11a for engaging with the
phos 10a, and a main additional hole 11b at a bottom surface of the recess 11m at a position f
corresponding to the hole 10b. 12 is a round screw. Other symbols are the same as in FIG. The
hole 10b is provided in advance with a female screw to be screwed with the screw (or a hole in
which a self-tapping can be done by the round screw 12 at any time.
+3) When fixing the speaker frame 11 to the sub baffle plate 10 with five speakers 3 as shown in
FIG. 2, insert the round screw 12 from the mounting hole 11b of the speaker frame 11 and screw
it into the hole 10b for fixing . Thus, the sub baffle plate 10 and the speaker frame 11 can be
fixed, and the mounting of the speaker 3 is completed. The height of the post 10a can be
determined by tie-casting at the time of molding, and the entire sub baffle plate 10 does not
become thick. Furthermore, since the portion of the round screw 12 for attaching the speaker
frame 11 does not come out on the front surface of the sub-baffle plate 10, not only the aesthetic
appearance is lost but there is no danger. 3 and 4 are partial sectional views of another speaker
system of the speaker frame of the present invention. In FIG. 3, reference numeral 13 is a nut,
and the hole 2b and the mounting hole 11b are provided at corresponding positions and fixed by
tightening the I screw 5 and the one nut 13. In FIG. 4, the mounting hole 11e is provided
separately from the mounting hole 11b, and is fixed to the mounting hole 11c through the
countersunk screw 5 as in the conventional example (4) of FIG. The mounting holes 11b and 11c
in FIG. 3 and FIG. 4 are provided in advance with female screws to be screwed together, or
mounting is holes in which a self-tapping can be cut by the countersunk screw 5 sometimes. In
the configuration of FIG. 3 and FIG. 4, the speaker frame 11 can be attached from the front of the
sub baffle plate 2 as in the prior art, and the speaker frame 11 is the conventional sub baffle
plate 2 or It can be used together with either of the sub baffle plates 10. Although the case of
attaching the speaker to frame 11 to the upper back, sub-baffle plate 2 in the embodiment has
been described, it goes without saying that the speaker frame 11 may be attached to the buckle
plate 1. As described above, according to the speaker frame of this invention, the speaker can be
attached to the sub baffle plate from the back side. Furthermore, if the soot 7 ban-full plate is
provided with a boss, positioning and fitting can be easily performed by fitting to the concave
portion of the spin (+1) force frame or the boss, and a portion where the screw is engaged Since
the above-mentioned boss can be taken longer, the sub-baffle plate can be attached more rigidly
than the layer surface of the sub-baffle plate without being thicker than necessary. In addition,
since the head of the screw for mounting the speaker is not exposed on the front surface of the

sub baffle plate, there is an advantage such as being able to have a change in design over the
conventional one.
