摘要：
A diaphragm for capacitance type loudspeaker is disclosed. The diaphragm uses a conductive high polymer layer as a conductor formed on a high molecular film of PET or the like by treating the high molecular film in a water solvent solution containing a conductive high molecular monomer, a chemical oxidizer and a dopant. The conductive high molecular monomer is selected from the group consisting of pyrrole, aniline, thiophene and derivatives thereof.
