NOVELTY - The invention claims a diaphragm, loudspeaker and earphone, relating to the electronic technical field. The utility model embodiment of the membrane comprises the first film layer and the second film layer, the first film layer comprises a first diaphragm and a second diaphragm, the second film layer comprises a third film and a fourth film, the first vibrating membrane and the second vibrating membrane composite, the third diaphragm and the fourth vibration film composite, and the first film layer and the second film layer are compounded by the second diaphragm and the third diaphragm, the third diaphragm is graphene diaphragm. The utility model embodiment of the membrane can obtain better exert the ductility of high-frequency, at the same time, it can both treble and sound effects with bass, experience feeling of the user with the diaphragm of the loudspeaker can send out sound with high fidelity, ensure the sound effect of high quality, which greatly.
