DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement
in the eyelet provided on the middle of the moving plate, which intervenes between the voice coil
lead wire and an external lead wire such as a gold thread wire connected to the terminal. ░ "I
41'C rich, 8. -Offer, let's say, oh, too. ???? In general, the loudspeaker is configured as shown
in FIG. 1 and is / IIIF12. That is, the frame 6 is coupled to the magnetic circuit 6 constituted by
the plate 2 having the center ball 1, the ring-shaped magnet 3, and the ring-shaped upper plate
4. The peripheral portion of the diaphragm 80 is coupled, the Heus coil 9 is coupled to the
central portion of the diaphragm 8, the middle portion of the voice coil 9 is held by the damper
10, and the voice coil 9 is held in the magnetic gap 11 of the magnetic circuit 6. Do not
encumber, fit in, dust cap 12 on the center top of diaphragm 8? Furthermore, a gold wire wire
with one end attached to a terminal 14 provided on a part of the frame 6 to the eyelet 13
provided at the middle of the diaphragm 8 with the drawing outs at both ends of the voice coil 9
Such as an external drawer @ 160 was connected to the end of the structure was configured n. In
the speaker having such a configuration, as the conventional eyelet 13, as shown in FIG. 2,
?SfmrM, LWdEVcIEmfb14, 6t4 1llaha-7 to 1L of the diaphragm 8 are provided, and an external
lead-out 16 is provided at the center of the eyelet 13. 3 Insert the tip and connect it to the

notebook 13 with solder 17 on the front of the diaphragm 8 together with the lead wire of the
voice coil 9 and apply adhesive 18 to the back of the diaphragm 8 to make the eyelet 13 and the
external leader The bond strength of line 16 was measured. 4) As shown in FIG. 3, the cylindrical
portion 19 having the weir 16 at only one end is passed through the small hole of the moving
plate 8 and the distal end of the cylindrical portion 19 is narrowed as shown in FIG. As shown in
FIG. 2, the wedges 16 are formed and held so as to hold the diaphragm 8. However, in such a tool
13, it is necessary to apply solder 17 and adhesive 18 for connecting and fixing the external lead
wire 16, and the solder 17 flows through the hole and burns the moving plate 8 or breaks the
lead wire of the voice coil. Careful attention was required for the work, such as induction, which
made the work so ugly. The present invention eliminates the above-mentioned conventional
drawbacks. Since the basic structure of the speaker is the same as that shown in FIG. 1, only the
characterizing part is shown by FIGS. The characteristic part of the present invention lies in the
tome 13. The tome 13 has the two wedges 16 for holding the diaphragm 8 in the same manner
as in the prior art and the cylindrical portion 19 is provided on the front side of the diaphragm 8.
The tip of the external lead wire 16 is inserted up to the tip of the cylindrical part 19 so that the
area for holding the external lead wire 15 is enlarged and joined only by the brazing force at the
time of stirring. .
Then, the lead wire 2Q of the voice coil 9 is wound around the cylindrical portion 19, and a small
amount of solder 17 is applied to connect to the eyelet 13. As shown in FIG. 7, the eyelet 13 is
fitted with a cylindrical portion 19 having one + j 416 at one end in a small hole of the
diaphragm 8, and the middle portion of the cylindrical portion 19 is narrowed to obtain FIG. As
shown in FIG. 5, the other s16 is formed, and the connection to the diaphragm 8 is measured,
and the cylindrical portion 19 remains and protrudes in the part 416. The external lead wire 16
is connected to such an eyelet 13 by inserting the tip of the external lead wire 16 so as to crush
the cylindrical portion 19, and the lead wire 20 of the voice coil 9 is connected to this. The
configuration is as shown in FIGS. As described above, since the speaker according to the present
invention is configured, connection of the external lead wire to the tome can be surely and easily
performed, the assembling workability is remarkably improved, and it is necessary to apply the
solder or the adhesive. It is also advantageous in reducing the mass of the vibration system, and
it is also advantageous to connect the lead wire of the voice coil by winding it around the
cylindrical part of the tome and soldering it with a small amount and burning off the pregnancy
board due to the outflow of the solder. It has the advantage of being able to prevent, and further,
improving the connection strength of the same to improve the reliability, etc., and is a large one
of the practical one curve value.
