▎ 摘　　要

NOVELTY - The planar diaphragm vibration system comprises diaphragm that has graphene film, an insulating layer and a voice coil that are sequentially stacked and arranged. The material of the voice coil is graphene. The thickness of the graphene film is ten to hundred nano-meters. The shape of the voice coil has scroll shape, a rectangular shape, a Z shape, or a hyperbolic shape. The planar diaphragm vibration system has fixing plate connected to the edge of the graphene film or insulating layer to make graphene film, the insulating layer, and the voice coil remain unfolded. USE - Diaphragm vibration system with planar diaphragm in earphone speaker (claimed) for simultaneous restoring of sound accurately with better sensitivity. ADVANTAGE - The system improve the transient response of the speaker and restore sound more accurately. Reduces the weight of the voice coil, improves the sensitivity of the vibration system. Improves the strength of the planar diaphragm vibration system, and facilitate subsequent installation to form a speaker. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a preparation method of plane vibration film vibration system; and (2) a planar diaphragm loudspeaker. DESCRIPTION OF DRAWING(S) - The drawing shows a exploded perspective view of a Diaphragm vibration system with planar diaphragm in earphone speaker.
