图2为本发明实施例提供的另一种录音装置的结构示意图；
图3为本发明实施例提供的一种录音方法的流程示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
参见图1，其示出了本发明实施例提供的一种录音装置10的结构，该录音装置10可以与移动终端相连接，用于移动终端进行录音，该录音装置10可以包括：拾音设备101和连接线102，其中，
拾音设备101，配置为采集录音装置10外部的声音信号；
连接线102，配置为将拾音设备101与移动终端进行连接，并且将拾音设备101采集的声音信号传输至移动终端。
示例性地，在本实施例中，拾音设备101可以是驻极体ECM，由于ECM具有高灵敏度、高信噪比、高输入声压级、高动态范围的特点，而且，通过提高ECM的供电电压，可以相应地提升ECM的动态范围和信噪比等指标，因此，选择ECM为拾音设备101可以比现有技术中的硅MIC有效地提高录音的质量。
此外，由于ECM具有较好的全向性特点，能够有效的改善现有移动终端的MIC对于拾音的方向性限制，优选地，连接线102具有弯折和旋转的性能，从而可以根据音源位置的变化控制ECM的拾音方向进行相应地变化。
示例性地，连接线102，还可以配置为从移动终端接收控制指令，该控制指令用于控制拾音设备101启动或停止采集录音装置10外部的声音信号的过程；可以理解地，连接线102具体可以是音频连接线，与移动终端的 耳机插口匹配；也可以是其他类型的能够传输指令及信号的传输线，本发明实施例对此不作具体限定。
示例性地，参见图2，录音装置10还可以包括开关103，与拾音设备101和连接线102相连，配置为开启和关闭拾音设备101采集录音装置10外部的声音信号的功能，并通过连接线102向移动终端传输拾音设备101采集声音信号的功能开启或关闭的状态信号。
需要说明的是，当移动终端通过连接线102接收由开关103传输的拾音设备101采集声音信号的功能开启的状态信号之后，移动终端才能够通过连接线102向拾音设备101发送控制指令，来控制拾音设备101启动或停止采集录音装置10外部的声音信号的过程。
本发明实施例提供了一种录音装置10，通过将录音装置10中的拾音设备改为ECM并且将该录音装置10外接于移动终端，从而提升了移动终端的录音质量。
结合上述实施例中所述的录音装置，参见图3，其示出了本发明实施例提供的一种录音方法，该方法可以包括：
S301：移动终端检测到录音装置采集声音信号的功能开启后，通过录音装置的连接线向录音装置的拾音设备发送用于启动拾音设备采集录音装置外部声音信号的第一控制指令；
示例性地，本实施例中所述的录音装置的结构和组成如前述实施例所述，在此不再赘述。
本发明实施例中，当录音装置的拾音设备通过连接线与移动终端相连之后，移动终端可以通过连接线对拾音设备采集声音信号的功能开启或关闭状态进行检测；当移动终端检测到录音装置的拾音设备采集声音信号的功能开启后，移动终端就可以通过连接线向拾音设备发送第一控制指令。
本发明实施例中，录音装置中还可以包括开关，配置为开启和关闭拾 音设备采集录音装置外部的声音信号的功能，还能够通过连接线将拾音设备采集声音信号的功能开启或关闭的状态信号传输至移动设备，以使得移动终端能够对录音装置的拾音设备采集声音信号的功能开启进行检测。
S302：拾音设备接收到第一控制指令之后，对录音装置外部的声音信号进行采集，并将采集的声音信号通过连接线发送至移动终端；以使得移动终端将接收到的声音信号进行保存；
示例性地，由于拾音设备优选为ECM，而ECM具有高灵敏度、高信噪比、高输入声压级、高动态范围的特点，并且还能够通过提高ECM的供电电压，可以相应地提升ECM的动态范围和信噪比等指标，因此，本发明实施例的拾音设备可以比现有技术中的硅MIC有效地提高录音的质量。
另外，由于ECM具有较好的全向性特点，能够有效的改善现有移动终端的MIC对于拾音的方向性限制，优选地，本实施例中录音装置的连接线具有弯折和旋转的性能，从而可以根据音源位置的变化控制拾音设备的拾音方向进行相应地变化。
S303：移动终端向录音装置的拾音设备发送用于停止拾音设备采集录音装置外部声音信号的第二控制指令；
可以理解的，与第一控制指令相对应地，当移动终端需要停止录音的时候，移动终端可以通过连接线向拾音设备发送第二控制指令，从而停止拾音设备采集录音装置外部的声音信号。
S304：拾音设备接收到第二控制指令后，停止对录音装置外部的声音信号进行采集。
本发明实施例提供了一种录音方法，通过将录音装置中的拾音设备改为ECM并且将该录音装置外接于移动终端，从而提升了移动终端的录音质量。
本发明实施例上述录音装置如果以软件功能模块的形式实现并作为独 立的产品销售或使用时，也可以存储在一个计算机可读取存储介质中。基于这样的理解，本发明实施例的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质中，包括若干指令用以使得一台计算机设备(可以是个人计算机、服务器、或者网络设备等)执行本发明各个实施例所述方法的全部或部分。而前述的存储介质包括：U盘、移动硬盘、只读存储器(ROM，Read Only Memory)、磁碟或者光盘等各种可以存储程序代码的介质。这样，本发明实施例不限制于任何特定的硬件和软件结合。
