| Abstract: | This paper proposes a design method of MP3 player based on DAB（Digital Audio BroadcastJng） receiver. The system software and hardware designs are introduced. In this system, ARM7 MCU is used as the controller, SD Card is used to storage MP3 files, and audio decoder chip STA013 is used to decode MP3 files. Digital audio signals are converted to analog voice signals through D/A converter MAX9850, and then the earphones output the voice signals. |
