DESCRIPTION JPS60146600
[0001]
FIELD OF THE INVENTION The present invention relates to a device for attaching a cord to a
closed speaker box for connecting the closed speaker box to another device. Configuration of the
conventional example and its problems In recent years, componentization has progressed in the
field of audiovisual and video equipment, for example, CRTs, tuners and speakers have been
divided into four different devices9, radio cassettes are main body and speaker box Are becoming
more differentiated. On the other hand, with regard to sound, hi-fi is progressing, and as for the
speaker box, a completely enclosed type speaker box is increasing. The connection between the
sealed speaker and another device is generally performed by connecting a connection cord to a
connection terminal attached to each device. There are also others in which a cord directly
connected to a speaker in a speaker box is drawn out of the speaker box. Hereinafter, an example
of a conventional cord attachment device for a closed speaker box will be described. FIGS. 1a and
1b are a perspective view and a cross sectional view showing an example using a connection
terminal which is a first example of a conventional cord attachment device for a closed speaker
box. In the figure, reference numerals 1 and 2 denote front and rear cabinets constituting a
closed type speaker box, the speaker 3 is mounted on the front cabinet 1 and the connection
terminal 4 is mounted on the rear cabinet 2 with screws 5. The speaker 3 and the connection
terminal 4 are electrically connected to each other by the so-toe line 6 inside the speaker box.
When attaching the connection terminal 4, the rubber bunk 7 is used so that there is no noise or
noise 17 i 4 rL from the gap between the cabinet 2 and the connection terminal 4. The
connection between the other device and the closed speaker box is achieved by connecting a
speaker cord 8 for connection to the connection terminal 4. In the first conventional example of
the sealed type speaker box coat attachment as described above, one end of the IJ l 'wire 6 is
attached to the speaker 3 attached to the front cabinet 1 and the other end is attached to the
temporary cabinet 2 It is difficult to process lead wires 6 and to combine front cabinet 1 and rear

cabinet 2 in order to combine the cutting cabinet 1 and rear cabinet 2 after connecting to the
fitting connection terminal 4. It was necessary to make the lead wire 6 longer at the top.
Furthermore, as a result, a temporary combination of the front cabinet 1 and the rear cabinet 2
may cause a loose lead wire 6 inside the speaker box to cause resonance by touching the inner
walls of the cabinets 1 and 2 and other parts). was there.
In addition, since the number of parts is large, the cost is high and the number of operation steps
is also large. Next, as a second conventional example, a coat of a closed speaker box configured
to draw out a speaker coat directly connected to the speaker 3 to the outside of the speaker box,
with one terminal 4 for a toy as described above being stored. Description will be given based on
FIGS. 2a and 2b showing the mounting device. In the figure, the speaker cord 8 soldered to a
speaker (not shown) inside the speaker box is drawn out of the speaker box from the cord
drawing hole 9 formed in the cabinet 2, but this code F 8 is The pair of resin bundlings 10a and
10b is held in position t, so that it is inserted and fixed in the cord drawing hole 9 from the
direction of the arrow b, and FIG. B is a cross-sectional view after fixing. In the configuration of
the second conventional example as described above, the resin bushings 1 oa and 10 b need to
have hardness for preventing removal of the speaker cord 8, and as a result, between the cavity 4
and the resin bushings 10 a and 10 b Or, a gap is formed between the speaker cord 8 and the
resin bushings 102L and 1ob, and the sound is likely to be raining with the sealing property or
worse. SUMMARY OF THE INVENTION The present invention overcomes the disadvantages of
the prior art described above, is very low cost, can be easily assembled, has excellent sealing
performance, and causes resonance as well. It provides all cord attachment devices. SUMMARY
OF THE INVENTION In order to achieve the above object, the cord attachment device for an
enclosed type speaker box according to the present invention is connected to a speaker provided
inside the speaker box, and the inside speaker cord is fixed inside the front cabinet. In addition to
being fixed by sucking in with the holding rib formed on the temporary cabinet and keeping the
sealing property through the elastic cord bushing taken in the cord extraction hole, it is pulled
out from the outside, Furthermore, it is configured to be held by a cord stopper lip formed in the
vicinity of the coat draw-out hole outside the cabby soto. DESCRIPTION OF THE PREFERRED
EMBODIMENTS FIGS. 3 to 5 show examples of the code example of the closed type speaker box
in the embodiment of the present invention, and the same parts as the conventional example are
not shown with the same reference numerals. In FIG. 3 to FIG. 5, the speaker coat 8 directly half
a day on the speaker 3 is the notch groove 11 of the fixing rib 11 formed on the front chakineno
1-i. After being masked to L, it is pulled out from the knee 1-drawer hole 9 of the rear cam 2 to
the outside of the cabinet 2.
In this state, when the front cabinet 1 and the rear cabinet 2 are combined in the direction of the
arrow shown in FIG. 3, the cord 8 is formed on the front cabinet 1 into a solid column 11 and a
rear cabinet 2. It is pinched and held by the concave groove 12a of the pinching rib 12 and can

not be pulled out even if the cord 8 is pulled from the outside of the cabinet. Rubber coat puno
sink 131 which passed cord 8 beforehand after combining pre-cabey node 1 and rear cabinet 2.
Insert in the direction of the arrow No. 1 into the cord extraction hole 9 of the Cavey Soto 2
Then, with the cord 8 pulled out so as not to be loose inside the speaker box, the coat 8 is drawn
into the cord stopper lip 14 formed in the vicinity of the cord extraction hole 9, and the cord 8 is
inside the speaker box. Don't let it Then, the coat 8 is further wound around the coat winding
portion 15 formed on the outer periphery of the cord stopper rib 14. As described above,
according to this embodiment, the combination of the eye IJ cabinet 1 and the rear cabinet 2 can
prevent the removal of the speaker cord 8, and the cord 8 pulled out of the speaker box through
the rubber cord push sink 13. Is pulled out so as not to be slack inside the speaker box and then
absorbed into the cord stopper lip 14 to prevent resonance due to the contact between the cord
8 inside the speaker box and the cabinet inner wall and other parts, and The 1IJj stop of pushing
the inner coat 8 into the box also becomes an 11 "function. In addition, the rubber cord Bonnock
13 inserted into the court draw-out hole 9 and attached can be closely attached to the coat 8 and
the rear node 2 because of the characteristics of the rubber, and the sealing performance as a
speaker box Would be very honorable. In history, because the parts used are also very small, the
effect of Kos J и Town is very thick. In this example, the rubber cord PUNO / NK13 is used to
maintain the sealing property, but even in the case of other 4J chain bushings / not rubber, it is a
material rich in elasticity and like a / f: characteristic It is not -11 that says the same effect can be
obtained. In addition, after the coat 8 is drawn into the knee 1-retaining rib 14, an extra cord is
wound around the coat winding portion 15 formed in the rear cabinet 2 to prevent the cord 8
from being pushed into the speaker box. The effect of is more dog-friendly. Effect of the
Invention As described above, according to the present invention, the cord is temporarily fixed to
the front cabinet and the rear cabinet is combined, and the elastic go 1-b bus sink which has
been passed through the coat in advance is the cord of the rear cabinet It is very easy to insert in
the extraction hole and pull out the cord and then sink it into the cord retaining rib, which makes
the adhesion excellent and the coat attachment device of the closed speaker box which does not
cause resonance by the cord. The cost reduction effect can be obtained significantly by
eliminating the connection terminal housings.
