NOVELTY - This utility model claims a loudspeaker monomer, wherein the loudspeaker monomer is set with ball top (2) fixedly connected on said loudspeaker vibration film (6), said loudspeaker monomer comprises graphene capacitor (1), the first plate (11) of said graphene capacitor (1) is attached to said ball top (2) outside surface of graphene, the top ball (2) in the surface and the graphene are standing with electric charge, and polarity opposite, the graphene capacitor (1) and the second plate (12) as fixing plate and the ball top (2) in surface by electric conduction layer (9) is connected with electrical property. The loudspeaker monomer of the utility model monitors displacement of vibration film (6) by graphene capacitor (1) timely, in addition, the two dimension structure is unique and graphene, graphene is attached on ball top (2) except the surface, no limit from ball top (2), can be manufactured into multiple shapes.
