1、分享一个Unity中用于管理声音的声音管理器，适合于中小型项目。
2、借鉴了很多的源码，最后修改完成，吸取百家之长，改为自己所用。
3、源码如下：
1 /*
2 *
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 *
