ＮＢＲ等の樹脂を含浸した布。Conventional technology The conventional edge base material for the camera plate is a fixed edge made of 100% natural pulp that is integrated with the cone, and the free edge that is bonded to the cone is made of natural pulp, 5BR-
Cloth impregnated with resin such as NBR.
ウレタン発泡体などがあった。There were urethane foams, etc.
発明が解決しようとする問題点

発明はこの問題点を解決することの出来るスピーカ用振
動板を提供せんとするものである。Problems that the invention seeks to solve: Since the fixed edge is integrated with the cone,
lowest resonant frequency G. ) is high and deep bass reproduction is not possible.
Among free edges, natural pulp cannot be used with large inputs because the edges will break if the amplitude is too high.Furthermore, cloth and urethane foam are heavy and costly.Furthermore, with free edges, the cone part and edge part are molded separately. Since the diaphragm is then bonded together with an adhesive, the cost of the finished diaphragm becomes significantly higher. The present invention aims to provide a speaker diaphragm that can solve this problem.
問題点を解決するための手段
上記の問題点を解決するために本発明は、レーヨンを基

板を構成しようとするものである。Means for Solving the Problems In order to solve the above problems, the present invention impregnates a rayon-based nonwoven edge material with a phenol resin, and further coats the adhesive surface of the cone with a chlorosulfonated polymer. It is intended to construct a speaker diaphragm by coating the material and adhering it to the cone portion at the same time as molding.
作用
レーヨンを基材とした不織布エツジ材に成形性を良くす
るためにフェノール樹脂を片面に含浸し、さらにもう一
方の面にコーン部との接着のためにクロロスルフォン化
ポリマー樹脂を含浸し、コーン部と成形同時接着する。Function: One side of the rayon-based nonwoven edge material is impregnated with phenol resin to improve moldability, and the other side is impregnated with chlorosulfonated polymer resin for adhesion to the cone part. At the same time as the part and molding.
クロロスルフォン化ポリマーは熱硬化性樹脂であるため
成形時に高温で成形するとコーン部と接着され、振動板
完成品を得ることができる。Since the chlorosulfonated polymer is a thermosetting resin, when it is molded at a high temperature, it will be bonded to the cone part and a finished diaphragm product can be obtained.
実施例

。A non-woven edge material with a basis weight of 4tsgr/rrf, which is a mixture of rayon and polyester fiber at a weight ratio of 30%, is impregnated with phenolic resin with a solid content of 10% on one side, and after drying, chlorosulfonated polymer resin is applied on the other side. 40 gr
Impregnated with a basis weight of /d and dried. After punching this edge base material into a predetermined shape, the mold temperature was 180°C and the pressing time was 6.
A diaphragm was obtained by adhering to the cone portion at the same time as molding under geC conditions. The figure shows the sound pressure frequency characteristics of a speaker using the speaker diaphragm of the present invention and a speaker B using a conventional cloth edge. Since the product of the present invention is light in weight, it has a high sound pressure level and can reproduce even higher frequencies.
発明の効果
以上のように本発明の振動板は構成されるため、簡易な
製造方法で振動板を得ることができるため、大幅なコス
