Abstract

PURPOSE:To obtain a diaphragm for speaker with light weight, low cost and high input proof by impregnating phenol resin to a non-woven cloth edge material of which base material is rayon, coating modacrylic resin on the one side of the diaphragm and forming this side and a cone part and bonding them at the same time. CONSTITUTION:The diaphragm for speaker is constituted by impregnating the phenol resin to the non-woven cloth edge material of which base material is rayon, coating the modacrylic resin on the one side of the diaphragm, and forming this side and the cone part and bonding them at the same time. It is desirable as the edge base material that polyester resin is mixed to the rayon in a weight ratio 0-30%. Thus formability is maintained by the thermosetting phenol resin at the time of hot-forming. Besides, as the cone part and the diaphragm are bonded by the modacrylic resin, the diaphragm finished goods can be obtained with the low cost.
