具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获取的所有其他实施例，都属于本公开保护的范围。
在一些可选的实施例中，参见图1，图1是本公开实施例提供的一种Type-C接口控制电路的结构示意图，如图1所示，Type-C接口控制电路100包括：Type-C接口101，包括对称的第一引脚面和第二引脚面，所述第一引脚面及所述第二引脚面均包括复用引脚，每个引脚面的所述复用引脚用于传输至少两种类型信号；第一传输模块102，用于传输第一类信号；第二传输模块103，用于传输第二类信号；开关模块104，包括第一开关单元与第二开关单元，所述第一开关单元的第一端连接所述第一引脚面的复用引脚，所述第一开关单元的第二端连接所述第一传输模块102，所述第二开关单元的第一端连接所述第二引脚面的复用引脚，所述第二开关单元的第二端连接所述第二传输模块103；检测模块105，所述检测模块105的第一端连接所述Type-C接口101，用于检测所述Type-C接口101的连接状态，所述检测模块105的第二端连接所述开关模块104，用于根据所述连接状态控制所述开关模块104的第一端与所述开关模块104的第二端之间的连接关系。
本公开实施例中，Type-C接口101可以包括对称的两个引脚面，例如，可以包括对称的A引脚面(或者第一引脚面)及B引脚面(或者第二引脚面)。
本公开实施例中，第一传输模块102可以用于传输(包括接收及发送)第一类信号，例如音频模拟信号；第二传输模块103可以用于传输(包括接收及发送)第二类信号，例如通过USB数据线传输的信号。
本公开实施例中，检测模块105的第一端可以连接表征Type-C接口101连接状态的引脚，这里，Type-C接口101的连接状态可以包括第一连接状态，例如USB数据线接头正向插入与Type-C接口101连接的状态可以是第一连接状态；Type-C接口101的连接状态也可以包括第二连接状态，例如USB数据线接头反向插入与Type-C接口101连接的状态可以是第二连接状态。
检测模块105的第二端可以连接开关模块104，并可以根据检测模块105的第一端所检测到的Type-C接口101的连接状态，对开关模块104的第一端与开关模块104的第二端之间的连接关系进行控制。
例如，当检测模块105检测到Type-C接口101处于第一连接状态时，开关模块104可以按照第一预设连接关系实现第一端与第二端之间的连接；当检测模块105检测到Type-C接口101处于第二连接状态时，开关模块104可以按照第二预设连接关系实现第一端与第二端之间的连接。
其中，第一预设连接关系可以是开关模块104的第一开关单元的第一端与第一开关单元的第二端连接，开关模块104的第二开关单元的第一端与第二开关单元的第二端连接；第二预设连接关系可以是开关模块104的第一开关单元的第一端与第二开关单元的第二端连接，开关模块104的第二开关单元的第一端与第一开关单元的第二端连接。
这里，开关模块104的第一端与开关模块104的第二端之间的连接关系，可以理解为第一传输模块102和第二传输模块103这两个模块与Type-C接口101的两个引脚面的复用引脚之间的连接关系。
众所周知，Type-C接口101具有USB双面插接、引脚复用等功能，这使得Type-C接口101具备传输不同类型信号的能力。由于第一传输模块102与第二传输模块103传输的信号类型不同，其对应的传输协议也不同，因此，为了使Type-C接口101在两种连接状态下均能同时传输第一类信号和第二类信号，需要借助切换开关模式104相应的变更第一传输模块102和第二传输模块103这两个模块与Type-C接口101的两个引脚面的复用引脚之间的连接 关系。
这样，本公开实施例中，由于检测模块105可以根据Type-C接口101的连接状态，对开关模块104的第一端与开关模块104的第二端之间的连接关系进行控制，无论Type-C接口101处于何种连接状态，都可以保证第一传输模块102能够正常传输第一类信号，第二传输模块103能够正常传输第二类信号，以实现Type-C接口同时传输两种不同类型信号的目的。

在一些可选的实施例中，如图2所示，第一引脚面(A引脚面)包括第一正差分信号复用引脚(A引脚面的第6号引脚Dp-A)和第一负差分信号复用引脚(A引脚面的第7号引脚Dn-A)，第二引脚面(B引脚面)包括第二正差分信号复用引脚(B引脚面的第6号引脚Dp-B)和第二负差分信号复用引脚(B引脚面的第7号引脚Dn-B)；第一开关单元包括第一开关(开关R1-R2)和第二开关(开关L1-L2)，第二开关单元包括第三开关(开关Dp1-Dp2)和第四开关(开关Dn1-Dn2)；第一开关的第一端连接第一正差分信号复用引脚(R1连接A引脚面的第6号引脚Dp-A)，第二开关的第一端连接第一负差分信号复用引脚(L1连接A引脚面的第7号引脚Dn-A)，第三开关的第一端连接第二正差分信号复用引脚(Dp1连接B引脚面的第6号引脚Dp-B)，第四开关的第一端连接第二负差分信号复用引脚(Dn1连接B引脚面的第7号引脚Dn-B)。

在一些可选的实施例中，第一传输模块202为音频解码模块；第二传输模块203为通用串行总线USB模块。
本公开实施方式中，当第一传输模块202为音频解码模块，第二传输模块203为通用串行总线USB模块时，Type-C接口201可以实现同时听音乐(或通话)和充电(或传输数据)。这样，设置于移动终端上的耳机接口可以被Type-C接口201取代，即Type-C接口201可以既充当USB数据线接口，又充当耳机接口。这种接口的复用可以提高移动终端结构的整体性，并可以在一定程度上降低失效概率。
