According to the flexible electronics intensively applied to consumer product in future, a new flexible electrostatic loudspeaker driven by the electret diaphragm is developed. The electret diaphragms of flexible loudspeakers are fabricated by fluoro-polymer with nano-meso-micro pores and charged by the corona method at room temperature. The interior surface areas of the pores of the electret films are effectively to increase the retention and stability of charges. The experimental results reveal that the retention and stability of charges of the electret diaphragm is satisfied to drive the flexible electrostatic loudspeaker. The sound pressure level of the flexible electrostatic loudspeaker ( 60mm*80mm*1mm) is measured as 80 dB/0.2 W at 1 kHz and 20 cm distance.
