Abstract: An anti-interference flexible circuit board for an audio apparatus with a camera comprises an integrated ribbon multilayer structure. An outer conductive layer includes a differential signal line group for digital video transmission and a main clock line, covered by an electromagnetic shielding film to form a shielding cavity. The flexible circuit board further integrates an analog audio drive line group and an independent microphone ground line physically isolated from a main ground line network, connecting only at a terminal portion or a pad position. A package body provides outer-layer protection. Through this layered wiring and shielding isolation, common-ground interference in hybrid transmission of high-speed digital and analog signals within narrow spaces is effectively reduced.
