invention and a cross sectional view taken along the line of FIG. These are the perspective views
which show the state which accommodated the said speaker apparatus in the speaker storage
box. DESCRIPTION OF SYMBOLS 1 ... Speaker apparatus, 2 ... Speaker box, 3 ... Speaker. 4 ...

[Detailed description of the device] This device is a speaker! In the case of iii &, the speaker is
attached to the planar baffle plate attached to the cylindrical 1i 111 surface of the cylindrical
sleeve and the single box in a state of being recessed from the 1 l IF-direction, whereby the
speaker is opened on one surface of the cylindrical speaker box It is an object of the present
invention to provide a speaker device having a configuration provided to Conventionally, a
speaker device having a cylindrical speaker box is mounted on the ground or lower portion of the
cylindrical speaker box with the speaker facing upward or downward, and the eyebrows which
are further radiated upward or downward are A conical diffuser was attached to the front of the
speaker in order to diffuse the light (万 +, 4: "" F 'L). しかし、この1! In the IIC conventional
speaker device, the speaker mounting position is the ground ground portion Kll of the speaker
box, and the sound pressure from the speaker received by the box is significantly different
between the upper part and the lower part of the speaker box. It has the disadvantage of not
being obtained. The present invention eliminates the above-mentioned drawbacks and will be
described with reference to the drawings in conjunction with an embodiment thereof. 1 and 2 are
a partially cut longitudinal sectional view and a cross-sectional view taken along line 1-1 of an
embodiment of a speaker device according to the present invention. The speaker device 1 is
composed of a roughly cylindrical speaker box 2 and a speaker 5. The speaker box 2 is made of a

so-called paper tube having a cylindrical cap 1 and manufactured with a predetermined wedge O
if IFll, and a window hole 4a is provided at a position substantially at the height of the tIIii 1 i 1
portion 4b. . According to 5, it is a rectangular baffle plate made of plastic or the like and has a
medium heat sK 8 hole 51. The baffle plate 5 has upper and lower portions (2) via bow-shaped
plates 6a and 6b, respectively, and the jii portion is straight! ! The window hole 4aKm is attached.
Loudspeaker 3 is fitted with circular hole 5a VC of outer mfm 7 at-the baffle plate 5 and housed
in its entirety in the speaker box 2. It is attached and fixed to the front. Accordingly, in this case,
the front surface of the speaker 5 is at a position fe which is recessed by a predetermined
amount from the outer peripheral surface of the NJlls 4. The outer periphery 59 at of the lower
opening of the speaker box 2 is screwed to the peripheral edge of the hole 11 a of the plate 11 of
the storage box 10 described later. ing. Therefore, when the speaker device 1 is stored in the
storage box 10, the speaker device 1 is supported by the outer peripheral edge s9J of the drone
cone 9 as shown in FIG. 1, and the upper opening S of the speaker box 2 is It is closed by the
upper plate 12 of the storage box 10.
Therefore, according to the speaker device 1 configured as described above, the speaker 3 is
positioned at the middle height position of the cylindrical speaker box (3) 2 as described above.
0, therefore, when the speaker 3 sounds, the upper and lower S of the speaker box 2 receive
approximately the same level of sound pressure-this causes the sound pressure to act uniformly
over the entire surface of the speaker box 2 to produce a good sound. You can FIG. 3 is a
perspective view b showing a state in which the above speaker device 1 is stored in a speaker
storage box and used. The housing y stack 10 is formed by arranging and fixing the base plate
11 and the upper plate 12 in a square array of 4-prisms 13a to 13d (15d is not shown). The
other three sides of the plate 14 are covered with cloths 15a to + 5cVc such as Saran if they are
covered. When the speaker device 1 is stored in the storage box 10, the speaker device 1 is
inserted from below the base plate 11 through the hole 11at shown in FIG. 1 and stored, and
then the drone cone 9t-FIG. As shown, it fixes to the base plate 11, and is fixed. The abovementioned cloth 15d is stretched below the ceramic dowel 1 in parallel with the # 1 face of the
dowel 79. (4) In the above embodiment, the speaker device 1 is provided with one speaker 5, but
the present invention is not limited to this. Although the material of the speaker box 2 is a
cardboard, the present invention is not limited to this, and it may be other materials such as
wood, 1 Rasnakku etc. In the above embodiment, the speaker assembly 2 may be used. Although
the cone cone 9 is provided on the side of the base 11, the loudspeaker apparatus 1 may be
mounted on the hard-hardened base plate 11 without providing the doron cord 79. Furthermore,
in the above embodiment, the speaker box 2 is made of cardboard, so it has a sound absorbing
effect, but a sound absorbing material such as glass wool may be light-filled in the box 2 to make
the iron effect more effective. As described above, according to the speaker device which
becomes uninventive, the flat baffle plate is accommodated in the cylindrical surface 111 of the
cylindrical speaker box in a state of being recessed by a predetermined amount from the-surface,
and the speaker is used as the speaker o * mt- Since it is configured to be opened and attached to

2
the baffle plate, (5) the speaker box extends over the entire inner surface area as compared to
the case where the speakers are attached to the upper and lower portions of the conventional
cylindrical speaker box. It has features such as being able to receive a nearly equal sound
pressure and producing a good sound.
