Abstract:
The present invention discloses a speaker vibration diaphragm. The speaker vibration diaphragm comprises: a vibration diaphragm body, and a graphene film used as a conductive layer and compounded to one side surface of the vibration diaphragm body. The present invention further discloses a method for manufacturing the speaker vibration diaphragm, and a moving-coil speaker provided with the speaker vibration diaphragm. The speaker vibration diaphragm of the present invention comprises a vibration diaphragm body and a graphene film compounded to one side surface of the vibration diaphragm body. The speaker vibration diaphragm has the advantages of good conductivity, and the like.
