同時接着可能なスピーカ用振動板を提供することを目的
とする。Problems to be solved by the invention Fixed edge is integrated with the cone, so the minimum resonant frequency (FO) is high and heavy and low temperature regeneration is not possible.In free edge, natural pulp will break if the amplitude is too high. In addition, cloth and urethane foam are heavy and expensive, and free edge molding involves molding the cone and edge separately and then bonding them together with adhesive, which makes it difficult to complete the diaphragm. There was a problem that the cost of the product increased significantly. SUMMARY OF THE INVENTION An object of the present invention is to provide a speaker diaphragm that is low cost, has high input resistance, is lightweight, and can be bonded to a cone portion at the same time as molding.

る。Means for Solving the Problems In order to solve the above problems, the present invention impregnates a papermaking sheet material of natural pulp based on Manila hemp with a vinyl acetate-acrylic copolymer resin, and further chlorosulfonates it. This method attempts to construct a speaker diaphragm by bonding a cone part and a cone material impregnated with a polymer resin at the same time as molding.

Impregnated with chlorosulfonated polymer resin for simultaneous adhesion. Both the vinyl acetate-acrylic copolymer and the chlorosulfonated polymer resin are thermosetting resins, so when molded at high temperatures, they are bonded to the cone portion, allowing a finished diaphragm product to be obtained.

A papermaking sheet material having a basis weight of gr/rrl is impregnated with 8 grld of vinyl acetate-acrylic copolymer resin, and after drying, impregnated with 40 gr/d of chlorosulfonated polymer resin and dried. After punching this edge base material into a predetermined shape, it was bonded to a cone part at the same time as molding under conditions of a mold temperature of 180°C and a press time of 4SeC to obtain a diaphragm. The drawings show 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、軽量で
低コスト、高耐入力のスピーカ用振動板を簡易な製造方
法で作ることが性能で、これにより大幅な合理化が図ら
れ、工業的価値の大なるものである。Since the diaphragm of the present invention is constructed as described above, the performance is that a lightweight, low-cost, high-input-resistant speaker diaphragm can be manufactured using a simple manufacturing method, and this will result in significant streamlining. It is of great industrial value.
