BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of a speaker box according to the
present invention, FIG. 2 is a sectional view thereof taken along line 1 - 3, and FIG. 3 is a rear
view. 1: baffle plate, 2: side plate, 6: support pole, 8 = back plate, 9: screw hole. FIG. 1 FIG. 2 FIG.
105 - U.S. Pat. No. 5,191,194 (2 ') FIG. 3 106 -
DETAILED DESCRIPTION OF THE PROBLEM The present invention relates to a speaker box KiI
which is a single piece of a speaker box KiI (more specifically, a material made up of sera cola,
domestic fiber and bamboo box, water-based synthetic resin) Concerning the speaker box ○
Conventionally, most of the speaker box is made of wood, it is not suitable for mass production, it
is generally expensive and it is expensive. Various cabinets of synthetic tree 814 are proposed as
alternatives, but this is Because the mass is smaller than that of the wooden t, the chattering
sound in the resonance sound is (1) 3. ; It does not make a sound bite as a result, and is a
representative example of acoustic equipment, in fact it is not practically used as a speaker box.
In order to remedy these drawbacks, we propose to use resin concrete for the inventor of the
present invention, but this has the disadvantage of being expensive. SUMMARY OF THE
INVENTION The present invention has been made to eliminate such drawbacks, and it is an
object of the present invention to provide: $ 1 - containing seracoat, 9. 6 Compositions and 1,
multiple walls. Support, open. Is provided parallel to the baffle plate portion from the portion C ',
and at the same time, at least one loudspeaker mounting hole is provided in front of the baffle, so
that the loudspeaker box is provided because it is not integrally molded into a box shape, It is
successful to eliminate the drawbacks of conventional speaker boxes. BRIEF DESCRIPTION OF
THE DRAWINGS FIG. The loudspeaker box shown in FIGS. 1 to 3 comprises a baffle plate 1 and a
side plate 2] It is integrally molded using a later-described CERCOLOLA composition and has a
nine-box shape (0, said baffle plate IK has at least 1 It is because the equipped speaker mounting
hole 3.4 is provided. On the inner wall 5 of the side plate 2, a plurality of struts 6 are provided in
parallel so as to reach the inner surface of the baffle plate 1 from the opening toward the baffle

plate 1. In the opening of this side plate 2, it is necessary! , A step portion 7 is provided by
cutting off the inner edge thereof, and the back 1i8 is fitted in this portion. Therefore, the length
of the front support post 6 is such that the back plate 8 comes into contact with the front
support post 6, and the length of the front support post 6 is spider than the length of the side
face plate 2 by the thickness of the back board 8. A screw hole 9 is provided in the support
column 6 and is locked to the speaker box by the back plate 8 screw thread lo. Also, in the
speaker box according to the present invention, the side wall plate which becomes the bottom
surface is removed except for the placement and removal of the container itself, and the other is
such that the baffle plate l is narrower than the opening portion as compared with the opening
portion , It is preferable to provide a slope · The inclination is suitably lf, preferably about τ.
As shown in FIG. 2, the speaker mounting hole makes it easier to install the speaker by providing
the one step portion IO. According to the present invention, the b (3) - + 1 f □ □ \ CERCOLAR
composition used for the production of the speaker box is made of tea hand side fibers IAA '· 1' '1
~ 10 weight -1 Preferably 2 to 5% by weight and water □ (Wji, (containing 1 to 10 parts by
weight of 1 synthetic resin (in terms of solid content), preferably 2 to 5% by weight, necessarily!
Depending on the moisture, the resin O hardener, other additives and "1 '' 7 d '; t' s. There are
various things as Xi waterproof synthetic resin by homogeneously dispersing blended yoghud
strands etc. ___ ___ ___ ___ 0 Polyvinyl alcohol aqueous solution, polyvinyl acetate emulsion,
acrylic emulsion, latex and the like. Various kinds of curing agents should be selected, and
appropriate ones should be chosen from them, but - for example - sulfuric acid steel, weights potassium maleate, formaldehyde, melamine resin, organic acid> Its anhydride, etc. 0 Water
content is sufficient as long as it is necessary for hardening of dragonfly, including water 4 or
water derived from water solution. 0 Such a shellfish composition is added to a mold Ninth
filling, temperature of 120 ~ 200 ° C, 3 ~ 15 surprising (4) degree. 1 □, - Pressurized for 5 to 30
minutes and dispersed from the mold 0 As a result, a pure white box with a beautiful surface can
be obtained. As stated above, this thing can be painted arbitrarily. As mentioned above, speaker
box a, curtain splash fiber and aqueous synthetic resin are specified amount + '¥ ii'll! ! . It is used
as a material for the seracola composition which is contained (h 'S · ·, -, it is not only inexpensive
as compared with the conventional ones, but it is not 1', but reinforcing power and aqueous
synthesis 16 agglomeration to the resin 16 K 1 g Strength higher than 1 Large fAI · 9 J Joint can
be covered and detachable free. Moreover, because there is no seam with integral reed / mold,
the resonance ratio (Q value) is extremely low. ◎ Because the molding conditions are mild (since
it can be molded at low pressure), a mild steel or the like can be used It is also inexpensive from
the point. Furthermore, since the support pillars are provided on the inner wall, not only the
mechanical strength of the box is reinforced, but also it becomes a screw hole, so that together
with the good workability of the material, the attachment of the back plate to the part layer ◇
Also, - Faceplate sK Company's inclination is provided, so it is easy to remove from the mold.

temperature of 160 ° C., 5 Vcd Heat pressurized with pressure for 15 minutes to produce a
speaker box with the shape as shown in Figures 1 to 3 1, t of 1, moisture content 0.41%, specific
gravity 1.6, impact resistance is It was high, the surface was beautiful and painting was easy.
