DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker cabinet
of a speaker stem, in particular, in which two or more speakers can be installed, and to a speaker
cabinet in which mutual interference due to speaker vibration is suppressed to reduce noise. FIG.
1 is a perspective view showing a conventional speaker cabinet, FIG. 2 is a front view thereof,
and FIG. 3 is a cross-sectional view taken along the line A-A 'of FIG. Conventionally, in a speaker
cabinet in which two speakers can be installed as shown in the above (1) 7r-r / g), the speaker
cabinet is reinforced and installed in the speaker cabinet In order to suppress mutual
interference due to vibration of each speaker, a baffle plate for installing each speaker is
prepared separately, and reinforcing members 1a, lb, lc, ld are provided for attaching each baffle
plate to a cabinet Although a speaker cabinet is used, each baffle plate or plate etc. is connected
by a relatively stiff reinforcing material 1e etc. -1, so 21 vibrations of each speaker will occur. ?
Yu ? o, ? Nionia ah. The present invention relates to the improvement of the above-mentioned
prior art, in which the baffle plate for installing the speakers is reinforced, the interference
between the speakers installed on the baffle plate is effectively suppressed, and the speaker with
little sound deterioration is provided. It is intended to provide a speaker cabinet for realizing the
system. Hereinafter, the configuration of the present invention will be described in detail with

reference to the drawings. (2) FIG. 4 shows a perspective view of a speaker cabinet in which two
speakers can be installed. In the figure, the front baffle plate is provided with a groove 2
horizontally recessed so as not to cut the baffle plate, and the first portion 3 of the baffle plate
divided by the groove 2 and the second of the baffle plate It is possible to install one speaker
each in a part life. Well, along the inner circumference of the cabinet, reinforcements 5a, 5b. -,%,
5c, and 5a, 5b, 5c are provided, and further, reinforcements 5d, 5d are provided on the side
plates 7a, 7b of the cabinet. The reinforcing members 5d, 5d are opposed to each other with a
gap. The first portion 3 of the baffle plate and the second portion of the baffle plate are screwed
to the reinforcing members' a + 5b + 5C95d and 6a + 6b + 6c + aa thus configured, respectively.
Said reinforcing material 5a. A groove 8 separating the first portion 3 of the baffle plate and the
second portion of the baffle plate 5b, 5c, 5cj and 5a, 5b, 5c, 5d attached to the gap 5 separating
the reinforcing members 5d, 6d It corresponds.
(3) A front view of the present embodiment is shown in FIG. 5, and a B-B 'sectional view of FIG. 5
is shown in FIG. The cross-sectional shape of the recessed groove 2 may be V-shaped, circular
arc, or other various shapes, but in the present embodiment, a seven-shaped groove is taken as
an example. In the speaker cabinet of the present invention, as described above, one speaker is
installed in each of the first portion and the second portion of the baffle plate separated by the
groove (not recessed enough to cut the baffle plate) The first portion of the baffle plate and the
second portion of the baffle plate, since the first groove of the baffle plate and the second portion
of the baffle plate have different vibration modes. It is possible to sufficiently suppress mutual
interference due to the vibration of the speakers installed in the part, and it is possible to realize
a speaker system without noise. In the practice of the present invention, the baffle plate is not
limited to only the front surface, and the present invention can be practiced on baffle plates such
as the side, top, and back of the cabinet. Further, the present invention can be applied to a
speaker cabinet having another shape other than the hexahedral Scabica cabineno (4), and the
same effect as described above can be obtained. Furthermore, it goes without saying that the
same effect can be obtained even if the present invention is implemented not only in a speaker
cabinet in which two speakers can be installed but also in a desired position of a speaker cabinet
in which three or more speakers can be installed. .
