ELECTROSTATIC SPEAKER AND MANUFACTURING METHOD THEREOF AND CONDUCTIVE BACKPLATE OF THE SPEAKER |
摘要 |
An electrostatic speaker and a method for manufacturing the speaker are disclosed. Said speaker comprises a vibrating film; an electrode portion disposed on a surface of the vibrating film and joined with the vibrating film; and a conductive backplate spaced from the electrode portion by a distance, the conductive backplate forming a plurality of holes, the vibrating film being deformed and vibrated to generate and release a sound through the holes due to a variation of an electric field generated between the conductive backplate and the electrode portion, wherein the conductive backplate is covered by a polymer layer serving as a protective film. The covering polymer layer on the conductive backplate is capable of improving the stability of the electrostatic speaker and increasing its lifespan. |
