小なるスピーカにしか使用できない。Problems to be Solved by the Invention However, as shown in FIG. 2, the fixed type diaphragm has corrugations 2 formed around a cone portion 1 to form an edge portion. The diaphragm with this configuration is made of paper 9 synthetic resin film, etc., and is light overall and is effective in improving efficiency, but as an edge, it does not have a large compliance and is weak in strength, making it difficult to input. Can only be used with small speakers.

エツジが提案され、実用されてきたが、耐湿性に弱く、
強度が弱いという欠点を有していた。For this reason, edges for speaker diaphragms that are light, flexible, have good moldability, and have excellent strength have not been produced. For this reason, a free edge type edge in which the link valve seat is coated with a rubber material has been proposed and put into practice, but it is weak in moisture resistance and
It had the disadvantage of low strength.
そこで本発明は、軽くて、柔軟性があり、成形性、強度

る。EXAMPLE Below, the speaker of the present invention will be explained with reference to FIG. 1, which shows an example. In the figure, reference numeral 4 denotes a field part, and here it is an external magnet type field part, which includes a plate 6 with a center pole 5 erected in the center of the upper surface, a ring-shaped magnet 7 placed on this plate θ, and a ring-shaped magnet 7 disposed on this plate θ. A ring-shaped upper plate 8 is placed on the magnet 7, and these are bonded together with an adhesive.
