基于AT89C51SND1C单片机的MP3音乐播放器设计

Design of MP3 Music Player Based on AT89C51SND1C Single Chip Microcomputer

基于AT89C51SND1C单片机对MP3音乐播放器进行设计,单片机内部集成了MP3解码控制模块和USB控制模块,采用K9F2080闪存作为外存储器,放音电路采用CS4330,音乐文件通过播放器上的USB接口设备从PC机上直接下载,最终实现了MP3播放器最基本的播放控制、音量控制、音效控制和显示功能。设计方案设计简单,性价比高,低功耗,易扩展。由于采用通用单片机实现设计方案,可以很容易地移植到其他微控制器系统中,因而具有很强的实用价值。

A kind of MP3 music player is designed based on AT89C51SND1 C microcontroller,the MCU is integrate with MP3 decoding control module and the USB control module,a flash memory K9F2080 is used as external memory,cs4330 is used as playback circuit,music files are directly downloaded through the player on the USB interface equipment from the PC,finally the MP3 player control,volume control,sound control and display functions are realized.It has the characters of simple design,high performance-cost ratio,low power consumption,easy expansion.Because of the use of universal single chip microcomputer,it can easily be transplanted to the other micro controller system,and has strong market competition ability and practical value.
