▎ 摘  要

NOVELTY - The graphene thermoacoustic speaker (100) and novel material has a sound wave generating unit (200) provided with a grid structure support layer (220) for supporting a graphene thin film (210). A frame (110) supports the sound wave generating unit. A aperture hole is formed in the grid structure support layer with the lattice frame. The first electrode (140) and second electrode (150) are formed for applying the electric signal in the graphene thin film. USE - Graphene thermoacoustic speaker. ADVANTAGE - The sound pressure level is improved. The heat loss of the substrate is reduced. Thus the influence of the substrate is reduced. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene thermoacoustic speaker manufacturing method and novel speaker materials. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the graphene thermoacoustic speaker.
