本申请要求于2018年12月24日提交中国专利局、申请号201811583718.2、申请名称为“一种通信控制方法、装置、系统、充电盒及无线耳机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及便携式收听设备技术领域，特别涉及一种通信控制方法、装置、系统、充电盒及无线耳机。
背景技术
目前的耳机可以分为有线耳机和无线耳机，其中有线耳机需要左右两个耳机通过有线的连接方式组成左右声道，产生立体声效果，佩戴非常不方便。而无线耳机则是通过无线通信协议(例如蓝牙)与终端进行通信，其相对于有线耳机而言具有无需收拾数据线、使用便捷的特点。其中目前最新出现的真正无线互连立体声蓝牙耳机(TWS耳机)就是无线耳机中较为典型的一种，如TWS耳机的无线耳机，往往需要配套的充电盒为无线耳机充电，又需要与充电盒通信，用于使无线耳机进入配对状态和恢复出厂设置等操作。
现有技术中，若想要无线耳机在充电过程中与充电盒进行通信，往往需要在充电使用的2pin(如5V和GND)外，加入通信使用的3pin(如检测，TX和RX)，如图1中的5pin，需要占用比较大的面积，使得外观就会很笨重，与TWS耳机的小型化和美观相比矛盾；也存在充电使用的2pin上使用电力载波的方案，即充电盒在为无线耳机充电的同时，可以将通信信号调制的充电电压信号上与无线耳机进行通信，然而这样的通信方式需要配置专门的载波芯片，成本较高。
因此，如何能够使无线耳机可以利用充电使用的2pin在充电过程中与充电盒进行通信，减少pin的占用面积，兼顾小型化和美观，且避免采用电力载波方式，减少设置成本，是现今急需解决的问题。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
请参考图4，图4为本发明实施例所提供的一种通信控制方法的流程图。该方法可以包括：
步骤101：充电盒通过两个供电pin为第一无线耳机充电时，若需要与第一无线耳机进行通信，则获取第一待发送数据。
需要说明的是，本步骤中的两个供电pin可以为充电盒中设置的用于与无线耳机的两个充电pin连接为无线耳机供电的两个触点。如与图2中的无线耳机的两个圆形金属触点(充电pin)相对应的充电盒中设置的两个触点，或与图3中的无线耳机的两个触点(充电pin)相对应的充电盒中设置的两个触点。
其中，本步骤中的第一无线耳机可以为自身的两个充电pin与充电盒的两个供电pin连接的一个无线耳机(如TWS耳机)。本步骤中的第一待发送数据可以为充电盒中的处理器获取的需要在充电盒通过两个供电pin为第一无线耳机充电时，向第一无线耳机发送的数据。对于第一待发送数据的具体内容，可以由设计人员自行设置，如可以为用户操作充 电盒上的按键的人机交互设备，生成的用于控制第一无线耳机进入配对状态和恢复出厂设置的指令对应的数据。本实施例对此不做任何限制。
可以理解的是，本步骤中处理器获取第一待发送数据的具体方式，可以由设计人员根据实用场景和用户需求自行设置，如可以先分别判断充电盒是否需要与第一无线耳机进行通信，以及充电盒是否正在为第一无线耳机充电，若均是，再获取需要通过步骤102向第一无线耳机发送的第一待发送数据；也可以先获取需要向第一无线耳机发送的第一待发送数据，再判断充电盒是否正在为第一无线耳机充电，若是，则进入步骤102。本实施例对此不做任何限制。
步骤102：根据第一待发送数据，控制两个供电pin的输出电压对应互换，以使第一无线耳机根据对应的供电pin的输出电压的切换，在充电过程中获取第一待发送数据。
可以理解的是，本步骤的目的可以为充电盒中的处理器通过根据第一待发送数据，控制两个供电pin的输出电压对应互换，实现在对第一无线耳机充电的过程中，将第一待发送数据发送给第一无线耳机。如图5所示，处理器可以根据第一待发送数据，互换两个供电pin(A1和B1)的输出电压(5V和GND)，例如第一待发送数据为1010时，若第一无线耳机中的通信设备检测A1的输出电压的切换，即检测自身的两个充电pin(A2和B2)中的A2，则处理器可以先控制A1输出5V(VBUS，USB电压)，B1输出GND，再控制A1和B1互换(A1输出GND，B1输出5V)，使通信设备接收到1(5V)0(GND)，再重复一次上述过程，使通信设备在上述过程进行两次后接收到1010的数据。
需要说明的是，本步骤中的两个供电pin的输出电压的互换，可以为两个供电pin之间的输出电压互换，如图5中当前时刻A1输出5V，A2输出GND时，若下一时刻进行互换，则下一时刻A1输出GND，A2输出5V。
具体的，对于本步骤中处理器控制两个供电pin的输出电压进行互换的具体方式，可以由设计人员根据实用场景和用户需求自行设置，可以根据充电盒中的具体电路结构对应进行设置，如充电盒的充电输出设备的两个输出端(如图5中的5V和GND)通过开关电路(如图5中的模拟开关)分别与两个供电pin(如图5中的A1和B1)连接时，处理器可以根据第一待发送数据，控制开关电路切换导通每个供电pin的供电线路，如图5所示，切换导通A1与5V输出端和GND输出端的连接和B1与5V输出端和GND输出端的连接，使A1和B1输出的5V和GND相互转换。只要可以保证处理器能够根据第一待发送数据，控制两个供电pin的输出电压对应互换，本实施例对此不做任何限制。
对应的，本步骤中处理器根据第一待发送数据，控制两个供电pin的输出电压对应互换的具体方式，可以由设计人员自行设置，如可以根据通信需求控制两个供电pin的输出电压对应互换的速率，以实现任意速率的通讯需求，本实施例对此不做任何限制。
需要说明的是，本实施例是以充电盒在一个无线耳机(第一无线耳机)的充电过程中的通信为例进行的展示，对于充电盒在另一无线耳机(第二无线耳机)的充电过程中的通 信，即充电盒在两个无线耳机的充电过程中的通信，可以采用与本实施例所提供的方法相同或相似的方式实现，本实施例对此不做任何限制。
本实施例中，本发明实施例通过充电盒根据第一待发送数据，控制两个供电pin的输出电压对应互换，可以令第一无线耳机中的两个充电pin的充电电压对应互换，从而使无线耳机在利用两个充电pin的可切换的充电电压进行充电时，可以根据充电电压的切换获取第一待发送数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
请参考图6，图6为本发明实施例所提供的另一种通信控制方法的流程图。该方法可以包括：
步骤201：判断是否需要与第一无线耳机进行通信；若是，则进入步骤202。
其中，本步骤中充电盒中的处理器判断是否需要与第一无线耳机进行通信的具体方式，可以由设计人员自行设置，如可以通过是否检测到用户操作充电盒上的如按键或触摸屏的人机交互设备生成的第一无线耳机控制指令(如配对指令)，确定充电盒是否需要与第一无线耳机进行通信。本实施对此不作任何限制。
步骤202：判断是否正在为第一无线耳机充电；若是，则进入步骤203。
可以理解的是，本步骤的目的可以为通过判断充电盒是否正在为第一无线耳机充电，确定是否能够通过互换第一无线耳机对应的两个供电pin的方式，向第一无线耳机发送数据；若充电盒在为第一无线耳机充电，则可以通过接下来的步骤通过互换第一无线耳机对应的两个供电pin的方式向第一无线耳机发送第一待发送数据。
对应的，对于充电盒未为第一无线耳机充电的情况，即第一无线耳机充电完成或充电盒的两个供电pin未与第一无线耳机的两个充电pin连接，则可以直接结束本流程，不再向第一无线耳机发送数据；也可以在第一无线耳机充电完成的情况下，令通信过程中不再对第一无线耳机充电，如可以现有技术一般将供电pin切换到对应的通信线路，本实施例对此不做任何限制。
步骤203：获取第一待发送数据。
步骤204：根据第一待发送数据，控制开关电路切换导通每个供电pin的供电线路；其中，每个供电pin的供电线路包括充电盒中的充电输出设备的两个输出端对应的线路。
可以理解的是，本步骤中充电盒的充电输出设备的两个输出端(如图5中的5V和GND)通过开关电路(如图5中的模拟开关)分别与两个供电pin(如图5中的A1和B1)连接，本步骤的目的可以为处理器通过控制开关电路切换导通每个供电pin的供电线路，即改变供电pin连接的充电输出设备的输出端，实现对供电pin的输出电压的互换。也就是说，本 步骤中充电盒可以按两种方式为第一无线耳机充电，如图5所示，一种可以为A1输出5V，B1输出GND，即处理器控制模拟开关(开关电路)导通A1与5V输出端连接，关断A1与GND输出端连接，导通B1与GND输出端连接，关断B1与5V输出端连接；另一种可以为A1输出GND，B1输出5V，即处理器控制模拟开关(开关电路)导通A1与GND输出端连接，关断A1与5V输出端连接，导通B1与5V输出端连接，关断B1与GND输出端连接。
需要说明的是，本实施例是以充电盒在一个无线耳机(第一无线耳机)的充电过程中的通信为例进行的展示，即通过控制开关电路切换导通每个供电pin的连接的充电输出设备的输出端，在第一无线耳机充电过程中进行通信；对于充电盒在另一无线耳机(第二无线耳机)的充电过程中的通信，即充电盒在两个无线耳机的充电过程中的通信，可以由设计人员自行设置，如第二无线耳机对应的充电盒中的两个供电pin与其他充电输出设备的两个输出端连接或上述充电输出设备的其他的两个输出端连接时，可以采用与本实施例所提供的方法相同或相似的方式实现，本实施例对此不做任何限制。
具体的，若第二无线耳机对应的充电盒中的两个供电pin与第一无线耳机对应的充电盒中的两个供电pin均通过开关电路与充电输出设备的两个输出端连接时，即图5中的5V输出端和GND输出端不仅通过模拟开关(开关电路)与第一无线耳机对应的A1和B1连接，还通过模拟开关第二无线耳机对应的A1和B1连接时，本实施例所提供的方法还可以包括充电盒通过另外两个供电pin为第二无线耳机充电时，若需要与第二无线耳机进行通信，则根据获取的第二待发送数据，控制开关电路切换导通每个第二无线耳机对应的供电pin的供电线路的步骤；其中，每个第二无线耳机对应的供电pin的供电线路包括充电输出设备的两个输出端对应的线路。
对应的，为了保证充电盒的使用安全，若第二无线耳机对应的充电盒中的两个供电pin与第一无线耳机对应的充电盒中的两个供电pin均通过开关电路与充电输出设备的两个输出端连接时，本实施例所提供的方法还可以包括在不需要为第一无线耳机或第二无线耳机充电时，控制开关电路关断对应的供电pin与充电输出设备的输出端连接的步骤。以避免仅第一无线耳机充电时，对另外的两个供电pin输出电压的情况。
本实施例中，本发明实施例通过根据第一待发送数据，控制开关电路切换导通每个供电pin的供电线路，可以使两个供电pin的输出电压对应互换，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信。
请参考图7，图7为本发明实施例所提供的一种充电盒中通信控制装置的结构框图。该装置可以包括：
获取模块110，用于在充电盒通过两个供电pin为第一无线耳机充电时，若需要与第一无线耳机进行通信，则获取第一待发送数据；
发送模块120，用于根据第一待发送数据，控制两个供电pin的输出电压对应互换，以使第一无线耳机根据对应的供电pin的输出电压的切换，在充电过程中获取第一待发送数据。
可选的，发送模块120可以具体用于根据第一待发送数据，控制开关电路切换导通每个供电pin的供电线路；其中，每个供电pin的供电线路包括充电盒中的充电输出设备的两个输出端对应的线路。
可选的，该装置还可以包括：
第二无线耳机发送模块，用于充电盒通过另外两个供电pin为第二无线耳机充电时，若需要与第二无线耳机进行通信，则根据获取的第二待发送数据，控制开关电路切换导通每个第二无线耳机对应的供电pin的供电线路；
其中，每个第二无线耳机对应的供电pin的供电线路包括充电输出设备的两个输出端对应的线路。
本实施例中，本发明实施例通过发送模块120根据第一待发送数据，控制两个供电pin的输出电压对应互换，可以令第一无线耳机中的两个充电pin的充电电压对应互换，从而使无线耳机在利用两个充电pin的可切换的充电电压进行充电时，可以根据充电电压的切换获取第一待发送数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
请参考图8，图8为本发明实施例所提供的一种充电盒的结构框图。该充电盒可以包括：充电输出设备10、开关电路20、处理器30、第一供电pin40和第二供电pin50；
其中，充电输出设备10的第一输出端和第二输出端通过开关电路20分别第一供电pin40和第二供电pin50连接，用于为第一供电pin40和第二供电pin50连接的第一无线耳机供电；

可以理解的是，本实施例中处理器30可以通过控制开关电路20，导通第一输出端与第一供电pin40连接和第二输出端与第二供电pin50连接，或导通第一输出端与第二供电pin40连接和第二输出端与第一供电pin50连接，实现第一无线耳机对应的两个供电pin(第一供电pin40和第二供电pin50)的输出电压的互换，即处理器30可以执行对应的计算机程序时，实现上述实施例所提供的通信控制方法的步骤。
具体的，对于本实施例中的充电输出设备10、第一供电pin40和第二供电pin50的具体结构和类型，可以由设计人员自行设置，如可以采用与现有的充电盒中的充电输出设备10和供电pin相同或相似的方式实现，本实施例对此不做任何限制。

可选的，该充电盒还可以包括：第三供电pin和第四供电pin；
其中，充电输出设备10的第一输出端和第二输出端通过开关电路20分别第三供电pin和第四供电pin连接，还用于为第三供电pin和第四供电pin连接的第二无线耳机供电；
开关电路20，还用于根据处理器30的控制，导通第一输出端与第三供电pin连接和第二输出端与第四供电pin连接，或导通第一输出端与第四供电pin连接和第二输出端与第三供电pin连接。即处理器30可以控制开关电路20，在充电输出设备10的第一输出端和第二输出端连接的第一无线耳机和第二无线耳机进行充电过程中，与第一无线耳机和/或第二无线耳机进行通信。
对应的，开关电路20还可以用于根据处理器30的控制，同时关断第一供电pin40和第二供电pin50与充电输出设备10的两个输出端(第一输出端和第二输出端)的连接，和/或关断第三供电pin和第三供电pin与充电输出设备10的两个输出端(第一输出端和第二输出端)的连接。
本实施例中，实施例通过开关电路20根据处理器30的控制，导通第一输出端与第一供电pin40连接和第二输出端与第二供电pin50连接，或导通第一输出端与第二供电pin40连接和第二输出端与第一供电pin50连接，可以令第一无线耳机中的两个充电pin的充电电压对应互换，从而使无线耳机在利用两个充电pin的可切换的充电电压进行充电时，可以根据充电电压的切换获取第一待发送数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
请参考图9，图9为本发明实施例所提供的另一种通信控制方法的流程图。该方法可以包括：
步骤301：无线耳机充电时，检测充电pin的电压转换信息。
其中，本步骤的目的可以为无线耳机中的通信设备通过检测无线耳机中对应的充电pin的充电电压，即与该充电pin连接的充电盒中的供电pin的输出电压，确定电压转换信息。
其中，本步骤中的充电pin可以为无线耳机中的两个充电pin中的任意一个或全部，对于本步骤中的充电pin的具体选择，可以由设计人员自行设置，本实施例对此不做任何限制。
对应的，本步骤中的充电pin的电压转换信息，可以为该充电pin的充电电压转换对应的信息，如图5所示，该充电pin为A2时，A2的充电电压为5V时，该电压转换信息可以为1，A2的充电电压为GND时，该电压转换信息可以为0。
步骤302：根据电压转换信息，获取对应的数据。
可以理解的是，本步骤的目的可以为无线耳机中的通信设备根据检测得到的电压转换信息，获取对应的数据，如上述实施例中充电盒发送的第一待发送数据。
具体的，对于本步骤中根据电压转换信息，获取对应的数据的具体方式，可以由设计人员自行设置，如可以采用与现有技术相同或相似的方式实现，本实施例对此不做任何限制。
需要说明的是，本实施例的目的可以为无线耳机根据两个充电pin的充电电压互换，分析得到对应的数据。对应的，为了保证无线耳机充电不受充电pin的充电电压互换的影响，两个充电pin可以通过如全桥整流电路的电压转换器与充电设备(如现有技术中无线耳机中的充电芯片)的两个输入端，以利用电压转换器将两个充电pin的可互换的充电电压转换为固定的输出电压为充电设备供电，如图5所示，无论两个充电pin(A2和B2)的充电电压(5V和GND)如何互换，全桥整流电路的两个输出端均一个固定输出5V另一个固定输出GND。
本实施例中，通过无线耳机充电时，根据检测得到的充电pin的电压转换信息，获取对应的数据，使无线耳机可以在充电时，接收如充电盒的充电设备通过充电pin发送的数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
请参考图10，图10为本发明实施例所提供的一种无线耳机中通信控制装置的结构框图。该装置可以包括：
检测模块210，用于在无线耳机充电时，检测充电pin的电压转换信息；
接收模块220，用于根据电压转换信息，获取对应的数据。
本实施例中，通过接收模块220在无线耳机充电时，根据检测得到的充电pin的电压转换信息，获取对应的数据，使无线耳机可以在充电时，接收如充电盒的充电设备通过充 电pin发送的数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
请参考图11，图11为本发明实施例所提供的一种无线耳机的结构框图。该充电盒可以包括：充电设备60、电压转换器70、通信设备80和两个充电pin90；
其中，电压转换器70的两个输入端分别各自对应的一个充电pin一对一连接，电压转换器70的两个输出端与充电设备60的两个电源输入端连接，用于将两个充电pin的可互换的充电电压转换为固定的输出电压为充电设备供电；
通信设备80，用于检测对应的充电pin90的电压转换信息，并根据电压转换信息，获取对应的数据。
可以理解的是，本实施例中的电压转换器70可以为用于将两个输入端的可互换的输入电压转换为两个输出端输出的固定的输出电压的设备，如两个输入端中的第一输入端的输入电压为5V，第二输入端的输入电压为GND时，两个输出端的第一输出端的输出电压为5V，第二输出端的输出电压为GND；第一输入端的输入电压变为GND，第二输入端的输入电压变为5V时，第一输出端的输出电压依旧为5V，第二输出端的输出电压依旧为GND。具体的，对于本实施例中的电压转换器70的具体结构类型，可以由设计人员自行设置，如可以采用现有技术中的全桥整流电路，只要可以实现上述功能，本实施例对此不做任何限制。
其中，本实施例中的充电设备70可以为利用电压转换器70的供电对无线耳机进行充电的设备，如图3中的充电芯片。
具体的，对于本实施例中通信设备80与两个充电pin90的具体连接关系，可以由设计人员自行设置，如可以与一个充电pin90连接，也可以与两个充电pin90连接，只要可以保证通讯设备80可以检测到对应的充电pin90的电压转换信息，本实施例对此不做任何限制。
本实施例中，通过通信设备80在无线耳机充电时，根据检测得到的充电pin的电压转换信息，获取对应的数据；通过电压转换器70保证两个充电pin90的充电电压的互换不会对无线耳机的充电造成影响，使无线耳机可以在充电时，接收如充电盒的充电设备通过充电pin发送的数据，在不采用电力载波方式的情况下，实现了无线耳机利用充电使用的2pin在充电过程中与充电盒进行通信，降低了设置成本，减少了pin的占用面积，兼顾了小型化和美观。
