MP3 encoding method for audio signal, especially the use of MP3 format storage pared with other format audio signals, take up the space is little, but also can ensure the quality of audio and therefore is at present the most popular music format one. MP3 players are so popular. Now with MP3 features embedded terminal products have bee one of the trends of development. This paper introduce a MP3 player design based on uses AT89C51SND1C chip,which ATMEL pany produce for MP3 design detailed discuss the MP3 player hardware and software design process,use Protel99se software to draw MP3 schematic, make printed circuit boards, through Keil programming software design MP3 software,such as file decoding procedures, key control procedures, USB munication and control procedures,and FAT file management procedures and programming procedures, use the puter39。 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 2 第 1 章 每章標(biāo)題下空兩行寫內(nèi)容，每章另起一頁。 (2) 。 (6) 。如第二章第一圖編號(hào)為圖 21 圖 21 表居中排版，在表上方必須加表的標(biāo)注，用五號(hào)楷體居中，表中文字為五號(hào)宋體，居中， 如第二章第一表編號(hào)為表 21 表 21 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 5 ?? 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 6 第 3 章 ?? ?? ?? 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 7 第 4 章 ?? ?? ?? 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 8 第 5 章 ?? ?? ?? ? ? ?? ?? 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)（論文） 9 結(jié) 論 【結(jié)論兩字格式不需修改。 洛陽理工學(xué)院畢業(yè)設(shè)計(jì)論文 10 謝 辭 【下空一行直接添加致謝內(nèi)容。參考文獻(xiàn)一律要求是經(jīng)公開出版、發(fā)表的著作或期刊（論文）。 Hennessy J L.
