産業上の利用分野
本発明は各種音響機器て利用されるスピーカ用撮動板に
関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a speaker imaging plate used in various types of audio equipment.

などがあった。Conventional technology Conventional diaphragm edge base materials include 100% natural pulp fixed edge that is integrated with the cone, and natural valve seat and S as free edge that is bonded to the cone.
There were woven fabrics impregnated with resins such as BR and NBR, and urethane foams.

を大きくできない。Problems that the invention aims to solve: Since the fixed edge is integrated with the cone, the lowest resonant frequency is low. ) is high and heavy bass cannot be reproduced. On the other hand, among free edges, an edge based on natural parbunut cannot be used with a large input because the edge will be destroyed if the amplitude is too high.

。Furthermore, with conventional woven fabric and urethane edges, the process of molding the cone paper and the edge portion separately and then bonding the two together using adhesives resulted in a significant increase in the cost of the finished diaphragm product. . The present invention aims to provide a speaker diaphragm that can solve these problems.

得ることができる。Means to Solve the Problems The present invention involves impregnating an edge material based on woven fabric with a thermosetting resin, and further applying an acrylic resin on one side to maintain moldability and hardness with the resin. Since the resin has adhesive properties at high temperatures, it can be bonded to the cone part to obtain a finished diaphragm product.
実施例
以下、本発明の一実施例におけるスピーカ用振動板につ

ーン部と成形同時接着し、振動板を得だ。A woven fabric edge base material having a basis weight of 80 g r 7 m is impregnated with about 5 gr/m2 of phenolic resin having a solid content of 10 g, and dried at about 12 o'CK. After drying, one side is coated with about 40g/m2 of acrylic resin and dried at about 120°C. After punching this edge base material into a predetermined shape, it was bonded to the cone portion at the same time as molding under conditions of a mold temperature of 200° C. and a press time of 8 SeC to obtain a diaphragm.

きる。The figure shows the frequency characteristics of speaker A using the speaker diaphragm of the present invention and speaker B using a conventional cloth edge. In the product of this example, the weight of the edge material is light, and since there is no adhesive, it is possible to reduce the need for overlapping diaphragms, and it is possible to provide a speaker with a high sound pressure level and a higher high-frequency resonant frequency.
発明の効果
以上のように本発明の振動板は構成されるだめ、軽量で
低コストのスピーカ用振動板を簡易な方法で型造するこ
とが可能で、工業的価値の犬なるものである。Effects of the Invention As described above, the diaphragm of the present invention is constructed so that a lightweight and low-cost speaker diaphragm can be molded by a simple method, and is of great industrial value.
