本人是做web前端的，但对android有一定兴趣，准备找一个入手点来做一些android的东西，一直有一个想法，我用android的手机能否通过wifi、蓝牙或者是USB线来输出电脑的声音呢？用手机来作为外放音箱使用？
假如是蓝牙，能否用手机来模拟一台蓝牙音箱或者耳机？
假如是wifi，是不是要在pc端写软件来捕获pc的声音来发送到手机端app？这会不会有延迟？
假如是USB线的话，能否模拟成一块USB声卡，或者说android的调试模式能支持除了命令的串行数据传输？
求各位大牛指导，我这几个想法哪个更容易实现，优劣处是哪，可以从哪里开始？

Linux can use PulseAudio or Network Audio System to implement network sound services; based on TCP/IP protocol, implementation on Android requires cross-compilation

After all, it never came to fruition and has remained an idea.
I spent 10 yuan to buy a USB-powered FM transmitter, plugged it into the computer and used the mobile phone radio to receive it. The effect was achieved, and the sound quality was actually decent.
