DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker having
a terminal for connecting a lead wire drawn from a voice coil to a frame at a strong S and not to
be rotated by an external force. In general, the speaker is configured as shown in FIG. That is, the
frame 2 is connected to the plate 2 provided with the seven-pole pole 1 and the magnet wedge of
the magnetic head, the same (the field portion 6 constituted by the ring-shaped upper plate 4
The diaphragm 80 and the woven part are fixed together with the gasket 7, the voice coil e is
ringed at the center of the diaphragm и, the middle part of the voice coil 9 is supported by the
damper 10, and the lower part of the voice coil 9 is ntm * Insert the dust cap 12 on the center
part of the diaphragm 8 so that it fits properly into the magnetic gap 11 of s, and lead it out to
one part of the lead wire diaphragm 8 from the voice coil e. Then, the gold wire 11113 which is a
lead wire is drawn out from the portion, and the gold wire 13 is brought into contact with the
terminal 16 attached to the mounting tongue 14V-1 provided on a part of the frame 6. In view of
such a configuration, the conventional terminal 1-and the mounting tongue 14 are configured as
shown in FIGS. 2 and 3. That is, as shown in the second cabinet 8, the mounting tongue piece 14
is provided in a part of the frame e, and has a flat plate-like shape provided with a hole 17 for

inserting the rivet 1. The terminal 16 has a through hole 1a through which a rivet 16 is inserted
at the center as shown in FIG. 3, and is constituted by a flat terminal plate 21 fitted with
terminals 1e and go @@ on both sides thereof. A rivet 1411 is fitted to the holes 1y and 1s of the
mounting tongue 14 and the terminal plate 21 so that the rivet 1 и is oxidized to attach the
mounting snowflake 14 # L terminal plate 21 ?. In such a configuration, when an external force
is applied to the terminal plate 21, the terminal plate 21 rotates around the rivet 1, and tension is
applied to the gold wire 13 covered with the terminals 19 and 11 l 10 Ic. If the speaker is
operating, the gold lead wire 13 will follow the piston movement of the diaphragm 6 or contact
the diaphragm 8 or the damper 10 to generate an abnormal sound. Deterioration in the
characteristic side is caused, or fatigue of the gold wire 1s caused by heavy wire 1 is advanced
prematurely and disconnection occurs. Take # 6 lightning strips 14 and terminal boards for $ 6!
11e) There were various defects such as the problem of specializing in the development of
genuine capital and the like, causing the co-II & when the four habits occurred. The present
invention addresses the above-mentioned disadvantages of the prior art.
The present invention will be described with reference to FIGS. 4 to 7 of the drawings. The entire
speaker is almost the same as that shown in FIG. 1, and the only place where it is created is a
tongue with a plate and a minar, so only the new one will be described. First of all, what is shown
in FIGS. 4 and 6 is a fork wedge as the plate-attached tongue piece 22, and at both ends, pressing
pieces 24 and RB to be in contact with the upper surface of the terminal plate 23 are provided. In
the middle of .26, there is provided a receiving piece 2 which is in contact with the terminal plate
2317'IFii ". The terminal plate 23 is formed by extruding the B7??t ? 27 with the receiving
piece 2 at the central portion T? by extrusion, and the terminals 28 and 211 are bell-clamped at
both ends thereof. . 5) With respect to the length of the terminal plate 2a, the length of the
pressing piece 24.26 and the receiving piece 26 of the mounting tongue piece 22 is longer.
When the terminal plate 28i1 is inserted between the and the receiving piece 26 with the
concave portion 1827 as a guide and the insertion end of the terminal plate 23 contacts the
rising IL 24a, 25aF-1 of the pressing piece 24.28, the pressing piece 24.2B, the receiving piece 2
иии The front end of the terminal board projects from the side of the terminal board 23 to 1171
and the part coming out of the terminal board 23 is folded along the front end IC of the terminal
board 23 and the terminal board jls is folded at @a 24b, Iamb, 26b. Hold on to the watch. In
addition, what is shown in FIG. The notch portion SO is provided at one end portion of the 48
second child plate 2s of the second half portion ls and the receiving piece 26 (l-fold portion j14b,
28b, 26bEil to ensure one fixed portion. As described above, since the speaker according to the
present invention is configured, mounting of the terminal plate constituting the terminal is mtt,
and there is absolutely no such thing that it rotates even if an external force is applied (this is
because voice coil Apply tension to the gold wire that is the leader of the wire, give excessive
slack, contact the diaphragm or the damper at one production to generate abnormal noise, or
break the gold wire wire early to break it. 2 C or pressure-proof meeting, but also cause a

end point such as improving the production quality of the fish, and is a big thing in practical
fishing price smelting.
