为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
此外，术语“安装”、“设置”、“设有”、“连接”、“配置为”应做广义理解。例如，可以是固定连接，可拆卸连接，或整体式构造；可以是机械连接，或电连接；可以是直接相连，或者是通过中间媒介间接相连，又或者是两个装置、元件或组成部分之间内部的连通。对于本领域普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
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组合。下面将参考附图并结合实施例来详细说明本申请。其中，图1是根据本申请的第一实施方式的用于车辆的MIC切换装置的方框图，图2是根据本申请的第二实施方式的用于车辆的MIC切换装置的方框图，图3是根据本申请的数据选择器的电路原理图，图4是根据本申请的用于车辆的MIC切换方法的流程图。
如图1所示，本申请的一种用于车辆的MIC切换装置，包括：设置在无线耳机1中的控制器11、连接器12、数据选择器(MUX)13、无线耳机麦克风(MIC)14以及设置在车载设备2中的车载设备MIC 24。
所述无线耳机MIC 14设置在无线耳机1的内部，以用于接收用户的声音并且将该声音转换成声音信号。
所述连接器12设置在无线耳机1的内部，并且分别与所述数据选择器13和控制器12电连接，并且还能够与车载设备2电连接，所述连接器12检测所述无线耳机1与车载设备2是否连接，并且在所述无线耳机1与车载设备2之前连接时，所述连接器12生成一个连接信号，并且将该连接信号发送至所述控制器11。
具体的，本申请可以有两种方式来实现上述方案。
第一种方案，所述连接器可以包括至少一个PIN针(图中未示出)，并且当所述至少一个PIN针与所述车载设备中的接触点接触时，表示所述无线耳机1与车载设备2已连接，所述连接器生成了所述连接信号(例如，电压信号)，并且将该信号发送至控制器11，这种方案利用连接器已有的PIN针来判断是否连接，检测结果可靠，并且结构简化。
第二种方案，在所述无线耳机1或者车载设备2中设置有距离传感器(图中未示出)，该距离传感器用于检测无线耳机1与车载设备2之间的距离，当所述距离小于或等于预设的距离阈值时，例如该距离阈值可以为0，则表示所述无线耳机1与车载设备2已连接，所述距离传感器向所述连接器发送一个接近信号(例如，电压信号)，所述连接器在接收到该接近信号后生成所述连接信号。采用这种方案可以不占用连接器的PIN针，并且信号可靠不易被干扰，提高了本申请的MIC切换装置的可靠性。
所述车载设备MIC设置在车载设备2的内部，以用于接收用户的声音并且将该声音转换成声音信号。此外，在所述车载设备2与无线耳机1连接的状态下，该车载设备MIC与所述连接器电连接，从而使用户的声音通过该车载设备MIC被接收，并经由数据选择器13被输入至车载设备或者其他设备中，以被处理和使用。
所述数据选择器13分别与无线耳机MIC和所述连接器连接，用于选择性地接收来自无线耳机MIC或者所述车载设备MIC的声音信号，并且仅将一路声音信号输出。
具体的，如图1和图3所示，所述数据选择器13可以为两路输入一路输出的数据选择器，既2选1数据选择器，该数据选择器的第一输入端MIC_A_N和MIC_B_N与无线耳机MIC 14相连接，以接收来自无线耳机MIC 14的语音信号。该数据选择器的第二输入端MIC_A_P和MIC_B_P与连接器12相连接，从而在无线耳机1与车载设备2连接时，可以经由所述连接器12接收来自车载设备MIC 24的语音信号。所述数据选择器的控制端A_B_EN与所述控制器11连接，以接收控制器11的控制器信号，从而选择性地将第一输入端或第二输入端与数据输出端MIC_N和MIC_P连接。
继续参见图1，所述控制器11设置在无线耳机1的内部，并且分别与所述连接器12和数据选择器13连接。
该控制器11用于当接收到所述连接信号时，控制所述数据选择器接收来自所述车载设备MIC的声音信号。也就是说，当车载设备2与无线耳机1实 现连接时，连接器12向控制器11发送一个连接信号(例如，电压信号)，所述控制器11在接收到该连接信号后，向数据选择器13发送控制信号(例如，高电平或低电平)，以使所述数据选择器的第二输入端与连接器12相连接，由于连接器12已经与车载设备2中的车载设备MIC 24连接，因此使所述数据选择器接收来自所述车载设备MIC的声音信号，而无线耳机MIC不接收声音信号。
该控制器11还用于当未接收到所述连接信号时，控制所述数据选择器接收来自所述无线耳机MIC的声音信号。也就是说，当车载设备2未与无线耳机1连接时，所述控制器11在未接收到连接信号的情况下，向数据选择器13发送控制信号(例如，低电平或高电平)，以使所述数据选择器的第一输入端与无线耳机MIC 14相连接，因此所述数据选择器接收来自无线耳机MIC 14的声音信号，而车载设备MIC不接收声音信号。
如图2所示，根据本申请的第二实施方式，为了准确地检测所述无线耳机1是否已经被佩戴，所述无线耳机1还包括有光学传感器15，在所述无线耳机与人体接近，例如非常靠近耳朵时，可以向控制器发送一个表示耳机已经被佩戴的佩戴信号(例如，电压信号)，从而可以检测所述无线耳机是否被佩戴，使用光学传感器有许多优点，例如非接触和非破坏性测量、几乎不受干扰、高速传输以及可遥测和遥控等优点。
根据本申请的第二实施方案，所述控制器可以进一步地配置为，当接收到所述佩戴信号并且未接收到所述连接信号时，控制所述数据选择器接收来自所述无线耳机MIC的声音信号。也就是说，当车载设备2未与无线耳机1连接时，并且耳机已经被佩戴的情况下，所述控制器11才向数据选择器13发送控制信号(例如，低电平或高电平)，以使所述数据选择器的第一输入端与无线耳机MIC 14相连接，因此所述数据选择器接收来自无线耳机MIC 14的声音信号，而车载设备MIC不接收声音信号。
进一步的，如图1和图2所示，所述无线耳机1还包括近场降噪模块16，用于对所述无线耳机MIC接收的声音进行近场降噪，从而使无线耳机的MIC 可以更精准的采集到声音信号。
此外，所述车载设备2还包括远场降噪模块26，用于对所述车载设备MIC接收的声音进行远场降噪，从而使车载设备MIC可以更精准的采集到声音内容。
上面所描述的近场降噪模块的近场降噪以及远场降噪模块的远场降噪均为相关领域中的已有降噪方式，本申请在此不做详细的描述。
进一步的，所述无线耳机1可以为蓝牙耳机，所述车载设备2可以与车载控制器(例如ECU或MCU)通讯连接并且与车载控制器进行信息交互，所述车载设备2包括但不限于：车辆中控台、车辆中央仪表、车辆方向盘、车辆行车电脑、车辆行车记录仪和/或车载外部设备。此外，所述车载设备中具有控制器并且能够运行上述Android、IOS或者Windows等操作系统。另外，所述车载设备2包括：蓝牙模块21，该蓝牙模块21与所述蓝牙耳机进行通讯连接(图中的虚线所示)，以用于以无线连接的形式与所述蓝牙耳机发送数据或者接收数据。
此外，如图4所示，本申请还涉及一种用于车辆的MIC切换方法，所述方法能够应用至上面所描述的无线耳机和/或车载设备中，所述方法包括以下步骤S1至步骤S3：
步骤S1，本申请响应连接信号，该连接信号在所述无线耳机与车载设备连接时由数据选择器生成。
当接收到所述连接信号时，本申请执行步骤S2：控制所述数据选择器接收来自所述车载设备MIC的声音信号。
当未接收到所述连接信号时，本申请执行步骤S3：控制所述数据选择器接收来自所述无线耳机MIC的声音信号。
进一步的，在执行上述步骤S3之前，当检测到所述无线耳机未被佩戴并且未接收到所述连接信号时，本申请才执行步骤S3：控制所述数据选择器接收来自所述无线耳机MIC的声音信号。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以 用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
另外，本申请还涉及一种计算机设备，该设备包括存储器、处理器及存储在存储器上并可在处理器上运行的计算机程序，所述处理器在执行所述计算机程序时可以实现上面所描述的用于车辆的MIC切换方法。此外，本申请还涉及一种计算机可读存储介质，所述计算机可读存储介质存储有执行上面所描述的用于车辆的MIC切换方法的计算机程序。
