具体实施方式
以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的可选实施例仅仅用以解释本发明，并不限定本发明。
本发明实施例的原理是，使播放终端(例如手机)与请求终端(例如电脑)连接，利用播放终端自带的音频处理系统及扬声器系统将请求终端的声音通过外放出来。这样充分发挥了智能手机的便携性和信号处理能力，利用了手机的喇叭发声单元实现了电脑的声音外放。实施方案如下：
如图1所示，本发明实施例涉及一种通过请求终端请求、利用播放终端进行播放音频数据的方法，包括：
步骤S101，请求终端与播放终端之间进行连接，建立信号通讯的物理链路。
本步骤中，播放终端与请求终端之间进行连接，建立物理连接通路。请求终端中安装有播放终端的相应程序数据(上位机驱动软件)，程序数据包括：
请求终端与播放终端进行数据通信的通信协议数据；
请求终端发送给播放终端的控制命令数据；其中，控制命令数据用于控制播放终端开通音频数据的播放路径；即：由请求终端发送控制命令，使得播放终端端响应请求终端的控制指令，而开启播放终端端的音频数据由接收端口到喇叭外放的路径；
路径切换命令数据；其中，路径切换命令数据用于将音频数据的播放路径切换到数据发送路径上。即：请求终端的上位机软件启动后，请求终端将音频数据的发送路径由自身的音频发送路径切换到数据发送路径上，例如切换至通用串行总线(Universal Serial Bus，简称为USB)发送通路上。
另外，对于首次连接的播放终端和请求终端，请求终端检测到播放终端的接入，播放终端将自带的驱动程序下载到请求终端中，请求终端完成上位机驱动软件的安装。
步骤S102，请求终端和播放终端分别进行初始化操作，各自完成音频数据的通道切换。可选的：
请求终端启动上位机控制软件，发送要求声音传送的控制命令给播放终端。播放终端接收到该控制命令作出响应,并打通由数据接口端到中央处理器(Central Processing Unit，简称为CPU)、由CPU到音频编译码器(COder-DECoder，简称为CODEC)模块、由音频CODEC模块将模拟音频信号输出去驱动喇叭的整套通路切换。请求终端收到播放终端的初始化完成响应信号后，自身也做相应的音频信号输出通路的转换，将音频数据的传输路径切换到与播放终端发送数据的数据发送路径上。
通常，对于默认设置，播放终端则将自身的播放模式设置为声音外放模式；也可以根据需求设置为耳机模式，或者听筒模式。
步骤S103，请求终端将需要播放的音频数据发送给播放终端；播放终端接收后，经过处理后进行播放。
其中，播放终端将接收到音频数据通过CPU单元进行处理，转换为播放终端内部音频处理单元CODEC所能识别的格式传送到音频处理单元CODEC中去。音频处理单元CODEC将接收到的音频数据经过内部处理后转换为音频数据发送出去，该音频数据经过CODEC内部或者外部的放大器进行功率放大后，发送给播放终端自身的发声单元(喇叭)中去，从而实现声音的外放功能。
另外，如图2所示，本发明实施例还涉及一种为请求终端播放音频数据的装置，包括：
数据接口模块201，设置为与请求终端连接，接收请求终端发送的需要播放的音频数据；
数据处理模块202，设置为将所述音频数据转换为扬声器能够识别的驱动、播发数据，由扬声器进行播放。
其中，数据接口模块201还设置为：
将接收的音频数据转换为中央处理器CPU能够处理的音频数据；
所述数据处理模块202包括：
CPU处理单元2021，设置为将所述数据接口模块发送来的音频数据转换为编译码器能够处理的音频数据；
音频处理CODEC单元2022，设置为将所述CPU处理单元发送来的音频数据转换为扬声器能够识别的驱动、播发数据，由扬声器进行播放。
所述数据接口模块201还设置为：
判断所述请求终端上是否包括有用于驱动通信的程序数据，如果是，则接收请求终端发送的需要播放的音频数据，如果否，则将所述程序数据发送给所述请求终端，由其进行安装。
如图3所示，本发明实施例还涉及一种请求播放终端播放音频数据的装置，包括：
数据处理模块301，设置为将音频数据的传输路径切换到与播放终端传输数据的数据发送路径上；
数据接口模块302，设置为与播放终端连接，将需要播放的音频数据通过数据发送路径发送给播放终端。
其中，所述数据接口模块302还设置为：
当首次与所述播放终端连接时，从所述播放终端中下载用于驱动通信的程序数据，并进行安装。
所述程序数据包括：
与所述播放终端进行数据通信的通信协议数据；
发送给播放终端的控制命令数据；其中，所述控制命令数据用于控制所述播放终端开通音频数据的播放路径；
路径切换命令数据；其中，所述路径切换命令数据用于将音频数据的传输路径切换到与播放终端传输数据的数据发送路径上。
本发明实施例还涉及请求终端和播放终端，其中，播放终端利用上述的为请求终端播放音频数据的装置为请求终端播放音频数据。请求终端利用上述的请求播放终端播放音频数据的装置与播放终端连接，请求播放终端播放音频数据。可选的，请求终端和播放终端可以为任意的具有音频数据处理、发送、播放的终端，例如，可以为电脑、手机、平板电脑等设备。
下面，以手机和电脑为例，对本发明实施例技术方案进行详细说明：
如图4所示，电脑的音频数据请求手机播放，包括：
步骤S401，手机和电脑通过USB线连接。
本步骤中，如图5所示，手机与电脑通过USB数据线进行连接，建立信号通讯的物理链路。
步骤S402，判断电脑是否安装有手机的驱动程序，如果是，则转步骤S405，如果否，则转步骤S403。
步骤S403，电脑从手机中下载驱动程序，并完成安装。
步骤S404，电脑向手机发送声音外放请求信号。
步骤S405，手机自身完成初始化，并完成音频信号由USB经CPU到CODEC最后到喇叭的通路切换，反馈初始化完成信号给电脑。
步骤S406，电脑也完成自身其音频数据通过USB数据通道传输的切换。
步骤S407，电脑播放声音，从而传输到手机中，由手机同步外放。
本步骤中，如图6所示，当电脑中有声音数据需要同步外放时，电脑的处理器单元101(请求终端的数据处理模块)将要发送的声音数据发送到电脑的USB接口模块102(请求终端的数据接收模块)中。电脑的USB接口模块102进行信号处理，即将声音数据转换为传送的USB信号，通过USB数据线103发送到手机端的USB接口模块104(播放终端的数据接收模块)中。手机端的USB接口模块104接收并处理接收到的USB信号，将其转为CPU处理单元105能够处理的数据信号，并传送给CPU处理单元105。CPU处理单元105将包括有音频信号的数字信号处理成音频处理CODEC(COder-DECoder，编译码器)单元106能够识别的数据信号，并发送到音频处理CODEC单元106中去。音频处理CODEC单元106将接收到的数据信号处理后转换为外部喇叭的驱动信号，发送到发声单元107(喇叭)中去，从而实现了声音的外放。
另外手机与电脑的连接方式也可以由无线的方式实现。利用手机的无线收发电路与电脑连接，例如蓝牙模块、无线保真(Wireless-Fidelity，简称为WIFI)模块等与电脑相应的蓝牙模块、WIFI模块建立连接，这样打通了无线的连接通路，也可以实现声音的手机外放功能。电脑与手机的无线连接实现声音外放功能的物理链路如图7所示。当电脑中有声音需要同步外放时，电脑的处理器单元101(请求终端的数据处理模块)将要发送的声音数据传送的蓝牙/wifi无线通信模块102(请求终端的数据接口模块)中，经过该模块信号处理后以无线的方式发送出去，手机侧已经与电脑侧通过蓝牙/wifi的方式建立无线链路，手机侧的蓝牙/wifi无线模块104(播放终端的数据接口模块)将接收到了无线的声音数据信号经过自身处理后，将相应数据信号发送到CPU处理单元105中，CPU处理单元105将该包括有音频信号的数据信号转换成音频处理CODEC单元106能够识别的信号，发送到音频处理CODEC单元106中去，音频处理CODEC单元106将接收到的数据信号通过自身单元处理后，转换为外部喇叭的驱动信号发送到发声单元107(喇叭)中去，从而实现了声音的外放。
本发明实施例通过两个终端之间建立数据连接，建立音频数据的传送通道，一个终端的数据可以通过另外一个终端进行播放，扩展了终端的功能，增加了用户体验，并且具有实现方式简单、成本低的优点。
本发明实施例技术方案除了应用与手机与电脑之间的应用场景之外，还可以应用于以下场景：
请求终端(例如电脑)上保存有大量音频文件，例如学习录音(英文学习音频资料)，歌曲文件等。而播放终端(例如手机或者平板电脑)由于存储容量的考虑，并不希望将音频文件拷贝到播放终端进行播放。采用本发明实施例的技术方案，就可以实现在电脑侧请求播放歌曲，在手机上收听的效果；如果二者是通过无线连接，还可以实现在一定范围内移动收听的效果，而不必限定在电脑前。
另外，当自己的终端(例如手机或平板电脑)保存有一些音频文件，需要给其他人听时，但是，基于隐私考虑，又不想将手机给对方操作，这样就可以采用本技术方案，利用手机请求将音频文件由对方的手机播放，这样，对方就可以操作自己的手机收听这些文件了，也避免占用对方手机存储空间，而且增加了隐私保护。
工业实用性：通过上述描述可知，本发明通过两个终端之间建立数据连接，建立音频数据的传送通道，一个终端的数据可以通过另外一个终端进行播放，扩展了终端的功能，增加了用户体验，并且具有实现方式简单、成本低的优点。
尽管为示例目的，已经公开了本发明的可选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
