  3  *  开发时间：2018.11.20
  4  * 
  5  *  功能：用来对项目中的所有音频做同一的管理
  6  *  
  7  *  描述：
  8  *      1、挂载该脚本的游戏物体上要挂载三个AudioSouce[可以修改脚本，动态挂]
  9  *      2、建议大的背景音乐不要加入AudioClip[]，对内存消耗大。而是哪里用到，单独使用PlayBackground函数播放
 10  *      3、小的音效片段可以将其加入AudioClip[]中，可以很方便的管理，可以通过声音剪辑、声音剪辑名称来进行音乐的播放
 11  *      4、该声音管理可以进行背景音乐的播放、音效的播放、背景音乐的音调改变、音效的音调改变、停止播放
 12  *
