NOVELTY - The utility model claims a diaphragm and comprising the diaphragm of the electroacoustic transducer, the diaphragm comprises substrate layer, the reinforced layer and reinforced layer coated on the surface of the glue layer, a substrate layer is polyether imide, polyethylene terephthalate, polyether-ether-ketone, polyphenyl thioether, polyurethane thin film made of any one material of the reinforcing layer is comprised of a mixture of graphene or graphene and graphite powder prepared through diluting agent uniformly, then, a glue coated on the reinforcing layer surface. The utility model of diaphragm has strong rigidity and can reduce the resonance frequency f0, increasing the high frequency sound pressure, improved high and low frequency characteristics. comprises the diaphragm electro-acoustic transducer stronger rigidity, low resonant frequency, a high frequency high sound pressure, high and low frequency performance.
