为使本发明的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
为了克服现有单终端设备播放时，由于终端设备的尺寸限制无法达到理想的多声道立体声播放效果的问题，本发明实施例中，使用多部终端设备利用无线信号进行同步控制，每个终端设备负责一个声道播放，多个声道之间不再受限于单机尺寸，可以根据声场搭建的需要灵活摆放，共同营造最佳的多声道立体声播放效果。并且该方法使用了生活中非常普遍的终端设备，比 如手机，平板电脑，笔记本电脑等，可以随时随地的进行组合搭建，非常灵活，便于音乐的分享。
如图1所示，本发明实施例提供的实现多声道立体声输出的方法，该方法包括：
步骤100，参与同一音源共同播放的主终端与从终端建立无线连接。
本步骤具体包括：
参与同一音源共同播放的主终端与从终端建立近距离无线连接；其中，所述近距离无线连接包括：wifi或蓝牙。
比如：主终端创建一个wifi热点，从终端搜索该wifi热点，如搜索到该wifi热点且准备参与共同播放，则尝试接入该wifi热点；或者，主终端打开蓝牙功能，从终端通过蓝牙搜索主终端，如搜索到主终端且准备参与共同播放，则与主终端进行蓝牙连接。
步骤110，主终端将音源信号转换成多个声道的音频信号，将多个声道分配给主终端和从终端，并将相应声道的音频信号发送至从终端。
其中，用户可以通过点击从终端的屏幕上显示的声道标识或点击主终端的屏幕上显示的位置图等方式来激活声道改变指令。
在主终端将相应声道的音频信号发送至从终端时，本步骤还包括：将相应声道的声道标识发送至该从终端；
进一步地，从终端在屏幕上显示接收到的声道标识，供用户根据所述声道标识确定所述从终端在声场中的摆放位置。
步骤120，主终端和从终端同步播放各自声道的音频信号，营造多声道立体声的声场效果。

主终端接收到用户直接输入的，或从终端转发的改变声道的指令时，本发明方法还包括：主终端重新为从终端分配声道，并将相应声道的音频信号发送至从终端。这里，用户可以直接输入从终端的声道号，进行自定义分配。 如果是来自从终端的改变声道的指令，因为总声道数跟从终端数一样多，如果有从终端要调整声道，那么必有其他从终端被占用的声道需要调换。具体实现可以在要改变的从终端上输入跟哪个从终端调换即可。
进一步地，主终端为从终端分配或重新分配声道后，本发明方法还包括：所述主终端在屏幕上显示与声道分配对应的主终端和从终端的摆放位置图。

其中，低音单元可以是具有低频效果(LFE，Low Frequency Effect)音频信号播放能力的设备，比如，低音音响设备。
如图2所示，假设五个终端如终端1～终端5，以及一个可选配的低音单元如终端6，通过无线连接后构成一个5.1声道的播放组，假设终端1作为主设备，在其屏幕上显示该播放组中每一个成员的声道标识，如图2中，L为左声道，C为中间声道，R为右声道，LS为左环绕声道，RS为右环绕声道，LFE为低频效果声道。
其中，每一个声道的音频信号中包含同步信号，同步信号用于多声道的音频信号同步播放。
主终端或从终端可以为以下任意一种设备：手机、平板电脑或笔记本。
为了实现多声道立体声输出，首先，主终端发出连接指令，与每个准备接入该系统的从终端建立无线连接；然后，主终端可以根据此时系统中接入的设备总数量，将音乐信号转换成多声道的信号，如果主终端监测到无线连接中含有低音单元，则从音乐信号中单独分离一路低音信号分配给该低音单元；然后，主终端将各声道的标识发给各从终端，并且在主终端的屏幕上显示出各终端的摆放位置推荐图，各从终端接收到声道标识后将其显示在屏幕上，如果使用者不满意系统自动分配的声道标识，可以通过手动点击设备屏幕上的声道标识来更换；然后使用者根据主设备屏幕上的摆放位置推荐图和 各设备的声道标识来摆放各设备的空间位置，在主终端上点击播放，主终端将各声道对应的音频信号(含同步信号)通过无线发送给相应声道的各从终端，最后各终端(主终端、从终端)共同来播放一首音乐，完成营造多声道立体声的声场效果。播放期间，使用者还可以根据个人需要，任意调整各终端的位置，从而达到最适合自己的听觉效果。
