DESCRIPTION JPS5045619
11+3. Patent applicant 4, agent 6, list of attached documents # 1111 Title of the invention
Loudspeaker diaphragm etch manufacturing method 2 Patent finish of heat treatment of # &
plastic synthetic fiber and Niyu cellulose fiber etc. with a heat setting property as a base material
Synthetic rubber or synthetic resin on the surface A method of manufacturing a speaker
diaphragm etch in which a waxed material is shaped by an added plate.
a 'Detailed description of the invention The present invention relates to the manufacturing
method of the speaker aiMI plate edge 従 来 In order to shape the edge material of the
conventional speaker m 敬 含浸 Immersion of thermosetting @ Jlh into non- # 8 applications etc.
It is already used in various ways to heat and mold thin films of synthetic rubber and synthetic
resin on the surface of a base material. . In this way, N can stably supply N with a variegating
resin at the time of impregnation retroactively 1 and so on! ! It is difficult, therefore, the low
resonance frequency in the% property required for the heavi force. There were often a few
deaths and lack of affordability. The purpose of this @ Ming is to eliminate defects such as those
mentioned above. The edge material is 4 [Waiwa's woven and fine woven fabric as a base
material, and the respective fibers are beaten,-merged, and machined. Kneading, etc. to be
dehydrated, dried, and the like are the same as those of the prior art, but they are based on heat
"61 storm synthetic fiber" and Toyosu cellulose delicate one-sided covered woven fabric as an
edge material. Both fibers are left inside immediately after spinning. For this reason, heat of more
than energy of molecular mirror opening of Ki fiber is applied to overcome internal strain by
simultaneously applying heat energy of stable state which is shrunk at the same time as heat
reset property. Based on synthetic rubber-based (BB to BBIfR) i synthetic ii fat (urethane
elastoma). Polyester Elastomer)% -coated to make up the edge material. . Such an etch material is
considered to be suitable for heat-resistant synthetic fibers, and is reconsidered to be removed by

cooling. Even if it is taken out of gold, it will be made nine rudder without deformation. In this
way, the aim 椴 edge mounted in this way can industrially omit the stirring treatment process for
Xff1 like the conventional cotton cloth. In addition, it is possible to reduce the degree of fatigue
at the time of large input of the speaker by utilizing the characteristics such as the high fiber /
gloss rate of synthetic fiber and the high degree of bending fatigue. For example, the following
table shows performance vs. proportion of the low-resonance frequency fO of the speaker using
the withdrawal plate etch according to the present method and the speaker using the sliding
plate edge according to the conventional manufacturing method. According to this table, it is
impossible to reduce the directionality of the speaker, i.e., the change in fO according to the
present method or the change in fO. In addition, w 4 / Figure, Figure 42 (It is also possible from
the special residence of the speaker shown here that n '4: can be engaged. That is, Fig. 7 shows
Korean and American clothing 3! [It is due to the law, and the M cofigure is according to this
surface method, but the line segment by the infertility is less fatigue of etch, 21! !
The valley of the roaring sound by Hm becomes small, and it is ゐ: Waka slope. In addition, in
terms of-side, it is funny (it is a test system, and the hiring is the characteristic aIvj after a test! で
あゐ。
BRIEF DESCRIPTION OF THE FIGURES FIG. 2 and FIG. 2 (D) reduce the size of the speaker
according to the conventional manufacturing method and the present invention according to the
conventional manufacturing method and the present invention, respectively. 塩 弁 福 2 # Y 2-1EndPage: 2
