摘要

在信息，技术高速发展的今天，多媒体技术也越来越受到人们的重视。文章对当前使用较多的音乐播放器作出较详细的比较。经过阅读多张文献，分析了一些音乐播放器的功能并考虑了怎样能实现支持更多格式的音乐文件，怎样能满足使用者对播放器的需求。本文主要介绍了一个基于Java Applet来实现的音乐播放器的设计。并对系统开发中涉及到的关键技术作了探讨，简要分析介绍了Java技术和Applet 的工作原理，最后说明系统需要实现的功能。

音乐是一种声音符号，表示人的思想感情。是人们思想的载体之一。音乐是有目的和内涵的，其中隐含了作者的生活体验，思想情怀。一款好的pc音乐播放器不但能够提供好的音乐播放效果，更能够为用户提供方便的操作。

本设计利用java语言和eclipse 编辑工具对播放器进行编写。同时给出了详细的系统设计过程、部分界面图及主要功能运行流程图，本文还对开发过程中遇到的问题和解决方法进行了详细的讨论，该音乐播放器集播放、暂停、停止、快进、快退、下一曲、上一曲、音量调节等功能与一体，性能良好。该播放器支持MP3、WAV、MP3和AIFF等音频格式。在开发的过程中采用瀑布模型。第一阶段首先对项目进行全面、仔细的需求分析，并准确做出项目进度安排，明确每个阶段的任务；第二阶段是进行项目分模块编码；第三阶段对项目进行

全面的测试和系统集成测试。

Abstract

In the information, the rapid development of technology today,the multimedia technology is becoming more and more attention. This paper makes comparison of the detail to the current use of more music player. By reading a plurality ofliterature, analysis of some function of music player and consider how to achieve the support more format music files,how to meet the needs of users of the player. This paper mainly introduces the design of a Java based Applet to achieve music player. And the key technologies involved in the system development are discussed and analyzed brieflyintroduces the work principle of Java technology and Applet,finally indicated that the system needs to realize the function.

The music is a sound symbolic expressing the mood and thinking. It i s the carrier of people's thinking. Music is the purpose and content, which implied the author's life experiences and feelings. A good pc music player c an not only provide good music playing effect, but also provide users with convenient operation.

The player is using java language and eclipse editing tools. Giving a de tailed system design process, part of the interface map and run flow chart of the main function, this article discussed in detail on problems and soluti on method in the development process. The music player set to play, paus e, stop, fast forward, rewind, and the next one, on a volume adjustment fu

nctions with one good performance. The player supports MP3, WAV, MP3, AIFF, etc. audio formats. The model in the development process is Waterfa ll model. The first phase is the project of comprehensive and careful needs analysis, accurately making the project schedule and clearing each stage o f the task. The second phase of the project is sub-

module coding. The third stage, the project testing and system integration testing.
