The present invention relates to a method of manufacturing a speaker edge and a dust camp. As
a conventional manufacturing method of a speaker edge and a dust cap, it is performed as shown
in FIG. 1 and FIG. As shown in FIG. 1 AK, the speaker edge is formed into a semicircular shape by
pressing the sheet 1 of the sheet 9 of foam rubber limp or synthetic resin into a predetermined
shape by a heating mold as shown in FIG. In the present embodiment, as shown in FIG. 1C, the
central portion is punched out into a disk shape. -Still, as shown in FIG. 2, the dust cap for the
speaker is formed by pressing the sheet 3 which is slightly harder than the end substrate with a
heating mold as shown in FIG. Then, as shown in FIG. 2C, the peripheral portion 5 is cut into a
predetermined size and manufactured. As described above, conventionally, the spill force edge
and the dust cap are separately manufactured, and in the case of the edge, the central portion is
not punched out, which is disadvantageous in the manufacturing process and effective utilization
of the material can not be measured. It was a significant disadvantage in terms of points. The
present invention is intended to eliminate the above-mentioned conventional drawbacks and to
provide a manufacturing method of a speaker edge and a dust cap which can manufacture the
edge and the dust cap at the same time and which is advantageous in cost. It is. In order to
achieve the above object, the present invention is characterized in that a reinforcing sheet is
wound in the center of a sheet serving as a base of an edge, and a heat and pressure molded
product is cut and separated into an edge and a dust cap. is there. An embodiment of the present
invention will be described below with reference to FIGS. 3 to 6. First, as shown in FIG. 3,
reinforcement that exhibits damping effect and reinforcing effect made of foamed polyester such
as foamed polyester at the center part of the sheet 6 suitable for an edge made of woven fabric
impregnated with acrylics and urethane resin. The sheet 7 is wound and pressure-formed with a
heating mold as shown in FIG. 4 to unify the two sheets 6.7 and, at the same time, the
semicircular curved portion 8 is placed in the central part A dome portion 9 is formed, and an
intermediate portion between the curved portion 8 and the dome portion 9 is cut to obtain a
speaker edge 1o shown in FIG. 5 and a speaker dust cap 11 shown in FIG. The reinforcing sheet
7 has a size that is slightly larger than the speaker dust cap 11 and has an outer diameter. As
described below, according to the method for manufacturing the speaker edge and the dust cap
of the present invention, the edge and the dust cap can be manufactured simultaneously in one
step, and the central portion of the edge is unnecessary. Therefore, it is possible to save 9% of the
cost of the dog of 9 industrial value, which is extremely advantageous in terms of cost, because it
can serve as a dust cap by simply bending the reinforcing sheet.
