    • 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.
    • 提供电子设备。 电子设备包括壳体和设置在壳体的内表面上的电声换能器。 电声换能器包括驻极体隔膜,导电板和至少一个间隔件。 驻极体隔膜位于壳体的内表面上并具有膜体和电极层。 膜体具有静电荷,并且电极层形成在膜体的下表面上。 导电板具有多个开口并且堆叠在膜体的上表面上。 间隔件位于驻极体隔膜和导电板之间,以保持它们之间的预定距离。
