PyQt phonon implement music player

Now online about PYQT's article is not much, say that official document is also rotten mess, first use phonon module encountered many questions,

Foreign sites related to more information, see some good examples recorded, mainly comments, give some hints to the later.

This code to achieve a single first on-demand, embedded in the program to achieve simple sound playback is good, if you want to do more professional, more closely to the modern player of the function,

I'll cover some of the more flexible and complex features in the next few articles.
