Description 譬 1, Name of Invention
Delon corn unit HD manufacturing method
3. Detailed Description of the Invention The present invention relates to a process for the
preparation of drone cone units. The drone cone is a diaphragm without a voice coil, also called
as a passive radiator, but acts as a port of a bass reflex type cabinet, and is used as a means to
improve the low kfW performance of the speaker system by resonance of the cone. There is. By
the way, as shown in FIG. 1 (IL), the conventional 7-piece drum of this drone cone unit is
manufactured by the method of joining the cones of the cone-like cone i1 ヲ pan cone speaker
and the 4-sided method. Then, as shown in FIG. 1V (b), the edge member 2 is attached to the
upper outer periphery of the cone paper 1, and then, as shown in FIG. 1 (Q), the center cap 3 is
attached and then the frame 4 is attached. On the other hand, the edge member 2 is fixed by the
packing 5, and the drone cone unit as shown in FIG. ! I left it. However, this conventional one. ·
Method 1 is a drawback that if you prepare the drone cone and the frame separately, and stick
the end member in the form line where the deceased person's cry 16 is combined with the jig,
EndPage: 1 and therefore the cost becomes 61 J was there. An object of the present invention is
to provide a method for producing a drone cone unit using the one in which the diaphragm and
the frame are integrally formed and the problems as described in i ')'] are solved. The invention
will now be described by way of an example. In FIG. 2, 20 is made of a hard resin material in
which the diaphragm 6 and the center cap T are integrally formed, and the transmission plate 6
and the frame 8 are integrally formed via the lip 9 on the heel? 7ft! The figure shows a
molded body. 10 is a long hole. In the present embodiment, along the elongated hole 10 of the
molded object, the end member 11 is attached to the menstrual blood as shown in FIG. 3 e), and
then the lip 9 is removed. The diaphragm 6 is held by the edge member 11 with respect to the
frame 8 as shown in FIG. From the above, as shown in FIG. 3 (0) as a whole, drone corn comes to
be finished. As described above, since the drone cone is manufactured only by removing the lip 9
after attaching the edge member 11, the cedar is extremely 1) single. From the above, according
to the present invention, it is possible to provide a cost-effective method of drying a drone cone
unit. 4、1. ° 1 simple explanation 'y1 Figures (&)-((1) are explanatory diagrams showing the
steps of the conventional drone cone unito manufacturing method, Figure 2 (IL) is a plane I24 of
the itll & molded body.
