摘要： An electronic device is provided. The electronic device includes a housing and an electro-acoustic transducer disposed on the inner surface of the housing. The electro-acoustic transducer includes an electret diaphragm, a conductive plate and at least one spacer. The electret diaphragm is positioned on the inner surface of the housing and has a film body and an electrode layer. The film body has static charges and the electrode layer is formed on the lower surface of the film body. The conductive plate has a plurality of openings and is stacked on the upper surface of the film body. The spacer is positioned between the electret diaphragm and the conductive plate to keep a predetermined distance therebetween.

摘要： A method for manufacturing electret diaphragms is provided. First, a dielectric film is attached to a frame by an adhesive material and a fastening element grips the peripheral area of the dielectric film on the frame. Afterward, the dielectric film is subjected to a metal sputtering process to form a conductive material layer thereon. Finally, the dielectric film is subjected to a polarizing process thereby forming an electret diaphragm.
