Description

一种实现音频信号收发的装置 技术领域
本文涉及但不限于音频信号处理技术，尤指一种实现音频信号收发的装置。
背景技术
众所周知，移动终端如手机中的实现音频信号收发的装置支持一个耳机插孔，兼容3段式耳机、美标4段式耳机和欧标4段式耳机等耳机类型。图1为相关技术中实现音频信号收发的装置的组成结构示意图。如图1所示，包括第一耳机插孔、第一控制单元如中央处理单元(CPU)、模拟开关和编解码器(Codec，Coder and Decoder)。
其中，第一耳机插孔，通过第一状态线连接到第一控制单元，通过第一插孔耳机总线连接到模拟开关，其中，插孔耳机总线包括左声道线(L线)、右声道线(R线)、接地线(GND线)和麦克风线(MIC线)。模拟开关，通过开关控制总线连接到第一控制单元，通过第一Codec耳机总线连接到Codec，其中，Codec耳机总线包括左声道线(L线)、右声道线(R线)、接地线(GND线)和麦克风线(MIC线)；模拟开关设置为在开关控制总线的控制下调整第一插孔耳机总线与第一Codec耳机总线的连接关系。由于在如图1所示装置中，两个总线的L线固定相连，两个总线的R线固定相连，因此所述模拟开关是设置为调整第一插孔耳机总线的GND线和MIC线，与第一Codec耳机总线的GND线和MIC线之间的连接关系，包括：第一插孔耳机总线的GND线和MIC线与第一Codec耳机总线的GND线和MIC线正常连接或者交叉连接；正常连接时，两个总线的GND线相连，两个总线的MIC线相连，交叉连接时，前者的GND线与后者的MIC线相连，前者的MIC线与后者的GND线相连。
需要说明的是，模拟开关不仅设置为调整其两侧的两个总线信号线之间的连接关系，还可以设置为调整其两侧的两个总线信号线之间的中断关系。 在如图1所示装置中，没有使用模拟开关的调整中断关系的功能。对于两个或两个以上模拟开关构成的模拟开关阵列，模拟开关阵列设置为调整其两侧的两个或两个以上总线的信号线之间的连接和中断关系。
Codec，通过Codec数据总线连接到第一控制单元，设置为编解码音频信号。需要说明的是，为了方便功能扩展，相关技术中Codec还支持第二Codec耳机总线(图1中未示出)、第一Codec输入总线和第二Codec输入总线(图1中未示出)，以及第一Codec输出总线和第二Codec输出总线等总线(图1中未示出)。其中，Codec输入总线包括两个或两个以上信号线，Codec输出总线包括两个或两个以上信号线。通常，Codec输入总线和Codec输出总线均包括5个信号线。
当耳机插入如图1所示的第一耳机插孔时，第一控制单元通过第一状态线检查耳机类型，根据检查出的耳机类型通过开关控制总线控制模拟开关调整连接关系，并通过Codec数据总线控制Codec的工作模式即控制Codec进入与开关类型对应的工作模式。
目前，移动终端中实现音频信号收发的装置，只支持一个耳机插孔，因此只能支持单插头耳机，无法兼容个人计算机(PC)耳机即双插头耳机，降低了相关移动终端的用户体验。

需要说明的是，Codec还可以通过第一Codec耳机插孔、第二Codec耳机插孔、第一Codec输入总线、第二Codec输入总线、第一Codec输入总线和第二Codec输出总线连接到模拟开关阵列；此时，
模拟开关阵列可以设置为调整上述6个总线中的任意两个总线的信号线分别与第一插孔耳机总线和第二插孔耳机总线的信号线之间的连接和中断关系。这样，本发明实施例装置可以实现支持多种音频信号收发和处理方案，提高了采用本发明实施例装置的移动终端的灵活性。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件(例如处理器)完成，所述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，例如通过集成电路来实现其相应功能，也可以采用软件功能模块的形式实现，例如通过处理器执行存储于存储器中的程序/指令来实现其相应功能。本发明不限制于任何特定形式的硬件和软件的结合。
本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围当中。
