本発明はスピーカ用エツジとダストキャンプの製造法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a speaker edge and dust camp.
従来のスピーカ用エツジおよびダストキャップの製造法
としては第１図、第２図に示すように行われていた。The conventional method of manufacturing speaker edges and dust caps is as shown in FIGS. 1 and 2.
ｉ〜ず、スピーカ用エツジは第１図ＡＫ示すように布９

を円板状に打抜いて製造していた。i~, the edge for the speaker is made of cloth 9 as shown in Figure 1AK.
A sheet 1 of foamed rubber or synthetic resin is pressure-molded into a predetermined shape using a heating mold as shown in FIG. 1B to form a semicircular curved portion 2, which is shown in FIG. 1C. It was manufactured by punching out the central part into a disk shape.

５を所定寸法に切語して製造していた。- Still, the speaker dust cap is made by pressure-molding the sheet 3, which is slightly harder than the edge base material, with a heated mold as shown in FIG.
It was then manufactured by molding it into a shape having a diameter of 100 mm, and then cutting the peripheral edge 5 to a predetermined size as shown in FIG. 2C.
このように従来ではスピル力用エツジとダストキャップ
を別々に製造しており、エツジの場合中央部が打抜くず
となってしまい、製造工程上不利になるとともに材料の
有効活用も計れずコストの点で著しく不利になるもので
あった。In this way, in the past, the edge for spill force and the dust cap were manufactured separately, and in the case of the edge, the center part was not punched out, which was disadvantageous in the manufacturing process, and the material could not be used effectively, resulting in increased costs. This was a significant disadvantage in that respect.
本発明は以上のような従来の欠点を除去するものであり
、エツジとダストキャップが同時に製造でき、コスト的
にも有利なスピーカ用エツジとダストキャップの製造法
を提供することを目的とするものである。The present invention eliminates the above-mentioned conventional drawbacks, and aims to provide a cost-effective manufacturing method for speaker edges and dust caps that allows the edges and dust caps to be manufactured at the same time. It is.
上記目的を達成するために本発明は、エツジの基材とな
るシートの中央に補強用シートを厘ねて加熱加圧成形し
たものをエツジとダストキャップに切断分離することを
特徴とするものである。In order to achieve the above object, the present invention is characterized in that a reinforcing sheet is placed in the center of a sheet serving as the base material of the edge, and the sheet is heated and press-molded and then cut and separated into the edge and the dust cap. be.
以下、本発明の実施例を第３図〜第６図により説明する
。Embodiments of the present invention will be described below with reference to FIGS. 3 to 6.

得る。First, as shown in Fig. 3, a sheet 6 suitable for edges such as woven fabric impregnated with acrylic nMts& or urethane wood.
A reinforcing sheet 7 made of foamed sesame resin such as foamed polyester and exhibiting a braking and reinforcing effect is placed in the center of the frame, and as shown in FIG. 7 is integrated, a semicircular curved part 8 is formed on the circumferential part, and a dome part 9 is formed in the center part, and the intermediate part between the curved part 8 and the dome part 9 is cut to form a speaker as shown in FIG. The edge 1o and the speaker dust cap 11 shown in FIG. 6 are obtained.
なお、補強用シート７はスピーカ用ダストキャップ１１
よりやや太き目の外径をもつ寸法とする心安がある。Note that the reinforcing sheet 7 is a speaker dust cap 11.
It is safe to choose a size with a slightly thicker outer diameter.

プの製造法によれば、エツジとダストキャップが一工程
で同時に製造でき、しかもエツジの中央部の不必要と。As described below, according to the method of manufacturing a speaker edge and a dust cap of the present invention, the edge and the dust cap can be manufactured simultaneously in one process, and the center part of the edge is unnecessary.
