******* 大 学 毕 业 设 计（ 论 文 ） 题目 基于单片机的 音乐播放器设计 作者 ***** 学院 *************学院 专业 电子信息科学与技术 学号 110802**** 指导教师 ****** 二〇一五 年 五 月 二十 日 摘 要 设计基于STC89C51单片机控制的音乐播放器，该播放器歌曲显示、彩灯伴奏，并红外遥控作为歌曲播放控制器，This thesis is describe a music player design based on 89c51 series single chip , the design is set of song’s information shows , lights accompaniment. And introduct the infrared remote control as the song’s controller in?a?creative?way, that make whole design are ornamental and ?handled easily.This design is divided into five modules, the five modules are Micro Control Unit（MCU）module, infrared remote control module, lights accompaniment module, voice module and Liquid Crystal Display（LCD）song information display module, the article made a simple introduction for each module, and has made the detailed instructions of music sound principles.This design using Keil software to debugging program of the system , and cooperate with Altium Designer（AD）for hardware circuit design and simulation, which making it smoother. Key words:?systems-on-chips; infrared controller;vocalism principle;The Altium Designer 目 录 摘 要 .....................................................................................................................................i 第一章 前言 ......................................................................................................................1 第二章 概论 .................................................................................................................... 2 2.1 单片机简介 ..............................................................................................................2 2.2 单片机特点及应用 ..................................................................................................2 第三章 系统硬件原理与设计 ....................................................................................4 3.1 STC单片机系统 .......................................................................................................4 3.2 红外接收模块 ...................
