本発明は復元性に富み、変形が少なく耐熱性、耐湿性の
優れたものを得ることのできるスピーカ用ダンパーの製
造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a damper for a speaker that is highly resilient, has little deformation, and has excellent heat resistance and moisture resistance.

好であること、変形が少ないこと、耐熱性、耐湿性が良
好であることなどがある。In general, speaker dampers are used to support the voice coil coupled to the speaker diaphragm so that it fits into the magnetic gap of the magnetic circuit without eccentricity.The performance required of this speaker damper is its resilience. It has good properties such as good hardness, little deformation, and good heat resistance and moisture resistance.

因となる欠点があった。However, speaker dampers manufactured using this method have poor moisture resistance and lack dimensional stability, so when incorporated into a speaker, they tend to bond poorly with the voice coil, resulting in abnormal noise when operating as a speaker. There was a flaw that caused this.
また、復元性についても良好とはいえず、スピーカのｆ

This change caused the sound quality to become unstable.
本発明は以上のような従来の欠点を除去するものである
。The present invention eliminates the drawbacks of the prior art as described above.
以下、本発明の実施例を図面とともに説明する。Embodiments of the present invention will be described below with reference to the drawings.

ンパーを得るものである。After applying trimethylolmelamine resin and an amine hardening agent to a base material made of cotton or a blend of cotton and synthetic fibers such as polyester, it is impregnated with modified Feimer resin and cresol resin, and then dried. ,
After preheating this base material for a few seconds at 100 to 150°C, it is heated and press-molded at a temperature of 230 to 250°C and a pressure of 2 to 3 at 2/α2 to produce a speaker as shown in Figures 1 and 2. This is to obtain a damper for use.
