DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a loudspeaker in
which the life of the lead wire is dramatically improved by connecting the lead wire from the
voice coil to the terminal without using the half EB. In general, the speaker is configured as
shown in FIG. That is, center ball 1t-plate 2 equipped with ring-shaped magne, etc.) 3. In the
same manner, 7 frames 6 are bonded to 1 "°" fv-) 4 K "" "q, q-6 d 26 and the diaphragm 8 is
adhesively bonded to the periphery of the frame 60 together with the gasket door. The voice coil
9 is coupled to the central portion of the diaphragm 8 and the middle portion of the voice coil 9
is supported by the damper 10 to fit the helical coil 9 to the magnetic gear 11 of the field I 6
without eccentricity. Attach a dust ヤ and a pin 12 at the center of the upper surface of the
vibration [8, and further, attach an input signal to the voice coil 9 in the drawer 1113t-frame 6
with W terminal 14 Configured. In such a configuration, since the lead-out wire 13 is always
swung by the vibration of the diaphragm 8 and the voice coil 9, a material having high flexibility
and high bending resistance is essential. As shown in FIG. 2C, a bevel wire formed by spirally
winding a steel foil 16 around a wire yarn 16 or the like is widely used. The JIil of the lead wire
13 at the terminal 4 of the conventional speaker is performed as shown in FIGS. 31a to 8. That is,

the terminal frame 18l17, which is made of a resin resin, is attached to the one frame KW and
the fine tongue piece 17) a of the 7 lam 6, and X * fj # is attached to the terminal 1 .. As shown in
the joy eall, the cylindrical middle square tube of the terminal @ 20 f integrally formed terminal
21 using the above screw 120 using a> tff, $ 1 'Figure 8 +! Terminal 1 as shown in II, insert 1fil
1130% end into upper ff 1u tome 11120, this is electrically and mechanically connected with 牟
1B 22 at 1120 and lead wire 1s and teranal 1aO * m You are good at needleing. In such a
configuration wL, when using a gold wire as the lead-out l113 in order to connect with the solder
22, the half 8822 is absorbed, and the solder 22 of the II consecutive plate or more at the gutter
portion 20 is drawn out and collected Toshibo, the contact with the terminal 14 as the fulcrum of
the swing of the lead wire 1s is coined on the solder 22 and there is no flexibility, no bending
self-reliance), short-term disconnection in MJh system That was it. The present invention has the
above-mentioned conventional drawbacks vtWk *.
In the following, an example of the present invention will be described with reference to the
attached section No. 嬉 418 mK. The speaker is the same as that shown in FIG. 1, so only the
terminal portion is shown here. That is, according to the present invention, a part Klj1 of the
frame 6 is attached to the terminal plate 23 made of synthetic resin and the terminal is warmed,
the long hole 241 of A is general, and here an oblong cylindrical shape as shown in FIG. A
terminal having a rectangular cylindrical shape and a snap s 26 as shown in the next terminal 26
° 12 al having a snap 926. As shown in the 13th vA, a long three-negative cylindrical ferrule
1l128 with a terminal 261ij inserted, and the end of the drawer 1a13 is inserted into the mate
52B, and the end plate 24 of the terminal plate 23 is an eyelet 928 14-伏 Twist from the bow
line and fasten it and squeeze it @ 28 Vt, and lock it so that it does not come out of the long hole
24 and hold the electrical and mechanical parts of the withdrawal rod 1s and the terminal 26 as
shown in FIG. This is a configuration of the terminal 14 that performs the target II. Thus, since
the speaker of the present invention is configured, there is no use of a half l18 for the * 1 of the
mains lead wire and terminals, so even if a gold-based wire is used as a lead wire, prefecture
softness resistance during folding III As the reliability deteriorates, it will not be eaten during the
break V * period, and the reliability can be greatly improved, and the assembly can be simplified,
the workability can be improved, and the cost can be reduced. It has great practical value.
