とを可能としている。(Function) In the present invention, by using the multicolor injection molding method, the bonding process between the diaphragm body and the diaphragm edge and the bonding process between the diaphragm edge and the diaphragm edge outer periphery fixing part (frame outer periphery) is simplified. Moreover, it is possible to almost completely eliminate these problems such as poor adhesion and incomplete adhesion.
また、スピーカガスケットおよびスピーカフレーム背面
のパツキンを同時に成形可能であり、−の部品が不要と
なるばかりでなく接着工程を不要としている。Furthermore, the speaker gasket and the packing on the back of the speaker frame can be molded at the same time, which not only eliminates the need for the negative parts but also eliminates the need for an adhesion process.
（実施例）
第１図ないし第４図は本発明の一実施例を示すもので、

形成されている。(Example) Figures 1 to 4 show an example of the present invention.
In these figures, 1 is a cone-shaped diaphragm, and this diaphragm 1
is formed by a diaphragm body 1a and a diaphragm edge ib on its outer periphery.
また、Ｉｃは振動板エツジ１ｂの外周に形成された断面

一部が設けられている。Further, Ic is a speaker gasket having a substantially rectangular cross section formed on the outer periphery of the diaphragm edge 1b, 2 is a frame to which the diaphragm 1 is attached via the speaker gasket 1c, etc., and the speaker gasket 1c is attached to the back of the frame 2. An integral gasket 1d is provided. Further, 2a is a frame flange portion, and a part of a gasket 1d is provided in a groove 2b of the frame flange portion.

な多色成形法が選択されることは勿論である。However, in the present invention, the diaphragm body 1a, the diaphragm edge 1b on its outer periphery, the diaphragm edge outer periphery fixing part, etc. are integrally molded by injection molding using a multi-color molding method, and are not separate members as in the past. Adhesive is used to bond them, so that they do not need to be integrated. In other words, the multicolor molding method produces molded products in two or three colors, and has two or three injection mechanisms, each of which injects the same resin or different materials into the mold. It is used to make molded products, and there are usually a variety of molds, such as two molds placed side by side or back to back, and molds that can print two or three colors. Of course, the optimal multicolor molding method is selected depending on the situation.
しかして、振動板エツジ部は、振動板エツジ１ｂ、スピ

る。Further, the diaphragm edge outer peripheral fixing portion refers to the frame 2 and the frame flange portion 2a, and these and the diaphragm body portion 1a may be made of the same material such as polypropylene. Further, ABS resin may be used as the frame material, and in this case, it is advantageous in terms of cost compared to polypropylene.
