摘要：作为一项与人们生活息息相关的应用，音乐播放器在人们的生活中发挥着不可替代的作用。本播放器在Linux(Debian 6.0)操作系统平台下进行开发，使用Qt程序开发框架实现播放器的GUI设计，并用Phonon多媒体API实现多媒体控制，最后再用C++编程实现。本播放器实现了音乐播放器的基本功能，包括“播放”、“暂停”、“上一曲”linux内核设计与实现 pdf、“下一曲”、“添加文件”、“删除文件”、“切换背景图标”、“最小化到托盘”等功能。测试表明，本播放器能够流畅地运行，并能很好地实现各项功能，并且有一定的容错能力，达到了设计预期的效果。同时，本播放器在稳定性、经济成本等方面都有不错的表现。

Abstract: As an application, which is closely related to the people's lives, music player plays an irreplaceable role in people's life. This Music player is developed under Linux (Debian 6.0) operating system with the Qt application development framework implementing the player's GUI design. Phonon multimedia APIs is used for multimedia control and at last coded by C++ programming language. The music player has realized basic functions of ordinary music player, including 'Play' function, 'Pause' function, 'Previous track' function, 'Next track' function, 'Add files' function, 'Delete files' function, 'Switch background icon' function, 'Minimize to tray' function and so on. The testing results show that the player can run smoothly and realize all of functions mentioned before. The player is provided with fault tolerance as well. To sum up, the player achieves the design's expected result. At the same time, the music player has a well performance in operational stability and economic cost.
