技术领域
本发明涉及便携式收听设备技术领域，特别涉及一种建立单线连接的方法、装置、无线耳机、TWS耳机及充电盒。
背景技术
耳机是一对转换单元，用于接收媒体播放器或接收器所发出的电信号，利用贴近耳朵的喇叭将其转化成可以听到的音波。
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，往往需要一个具有收纳和充电功能的充电盒。

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1，图1为本发明实施例所提供的一种建立单线连接的方法的流程图。该方法可以包括：
步骤101：无线耳机判断充电盒的供电触点是否为通讯模式；若是，则进入步骤102；其中，无线耳机的充电触点与充电盒的供电触点连接。
需要说明的是，本步骤中充电盒的供电触点和无线耳机的充电触点均可以包括充电模式和通信模式，即供电触点和充电触点均为充电模式时，充电盒可以对无线耳机进行快速充电；供电触点和充电触点均为通讯模式时，充电盒可以与无线耳机建立进行信息交互的单线连接。
其中，充电盒的供电触点和无线耳机的充电触点均为充电模式时，供电盒对充电触电的充电方式可以由设计人员自行设置，如可以为利用充电盒中的蓄电池对无线耳机进行充电，也可以为利用充电盒连接的电源对无线耳机进行充电，本实施例对此不做任何限制。
对应的，当充电盒的供电触点和无线耳机的充电触点均为通讯模式时，充电盒可以仅与无线耳机建立进行信息交互的单线连接；还可以同时对无线耳机进行慢速供电，即供电触点为充电模式，充电触点为通讯模式时，充电盒可以对无线耳机进行慢速供电。本实施例对此不做任何限制。
具体的，本步骤中充电盒的供电触点和无线耳机的充电触点可以为无线耳机放入充电盒进行充电时，无线耳机和充电盒相连的触点。对于充电盒的供电触点和无线耳机的充电触点的具体结构设置，可以由设计人员根据实用场景和用户需求自行设置，如供电触点和充电触点可以均包括两个pin脚，只要通过供电触点和充电触点的连接，充电盒可以建立与无线耳机进行信息交互的单线连接和对无线耳机进行供电。本实施例对此不做任何限制。
可以理解的是，本步骤的目的可以为无线耳机判断充电盒的供电触点是否为通讯模式，确定是否需要与充电盒建立单线连接。对于无线耳机判断充 电盒的供电触点是否为通讯模式的具体方式，可以由设计人员自行设置，如可以根据充电盒的供电触点处于供电模式和通讯模式时，无线耳机的充电触电的电压值的区别，通过判断无线耳机检测充电触点的电压值是否在预设范围内，确定充电盒的供电触点是否为通讯模式。只要无线耳机可以确定充电盒的供电触点是否为通讯模式，本实施例对此不做任何限制。
步骤102：将充电触点由充电模式切换成通讯模式，与充电盒建立单线连接。
可以理解的是，本步骤的目的可以为无线耳机在确定充电盒的供电触点为通讯模式，即确定需要与充电盒建立单线连接后，将原本处于充电模式的充电触点配置成通讯模式。对于无线耳机将充电触点由充电模式切换成通讯模式的具体方式，可以由设计人员根据实用场景自行设置，只要无线耳机可以利用充电触点与充电盒的供电触点的连接，与充电盒建立用于信息交互的单线连接，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通过无线耳机与充电盒建立的单线连接，避免现有无线耳机与充电盒之间的ble通信存在的广播扫描冲突问题。因此，在无线耳机与充电盒建立单线连接，即充电盒的供电触电和无线耳机的充电触电均切换为通讯模式后，无线耳机与充电盒可以直接通过该单线连接进行完整的数据传输；由于该单线连接的数据传输速度较低，可以无线耳机通过该单线连接向充电盒发送数据量较小的如电量信息和配对信息等状态信息，并且为了进一步提升无线耳机与充电盒的数据传输速度，可以通过该单线连接确定无线耳机与充电盒之间的ble通信的广播和扫描顺序，通过无线耳机与充电盒之间的ble通信进行完整的数据传输，即无线耳机和充电盒可以通过单线连接和ble通信进行信息交互。对于无线耳机与充电盒建立的单线连接后的具体信息交互方式，可以由设计人员自行设置，本实施例对此不做任何限制。
具体的，当无线耳机和充电盒可以通过单线连接和ble通信进行信息交互时，为了进一步减少无线耳机和充电盒的信息交互时间，无线耳机在确定充电盒的供电触点为通讯模式后，还可以直接启动ble扫描，接收充电盒通过ble广播发送的数据，即充电盒需要与无线耳机进行信息交互向时，不仅可以将供电触点由充电模式切换成通讯模式，还可以启动ble广播向无线耳机发送对应的数据，避免充电盒需要通过在单线连接建立之后告知无线耳机启动bie扫描的步骤，节省无线耳机和充电盒的信息交互时间。本实施例对此不做任何限制。
本实施例中，本发明实施例利用无线耳机的充电触点和充电盒的供电触点的连接，建立无线耳机与充电盒的单线连接，使得无线耳机与充电盒可以通过单线连接进行信息交互，提高了充电盒与无线耳机通信的可靠性，提高了用户体验。
请参考图2，图2为本发明实施例所提供的另一种建立单线连接的方法的流程图。该方法可以包括：
步骤201：无线耳机检测充电触点的电压值是否在预设范围内；若是，则进入步骤202。
其中，本实施例中的无线耳机的充电触点与充电盒的供电触点连接。由于充电盒的供电触点处于充电模式和通讯模式时，无线耳机的充电触点的电压值会对应进行变化，本步骤中的预设范围可以为预先设置的充电盒的供电触点处于通讯模式时，无线耳机的充电触点对应的电压值范围。本步骤的目的可以为通过检测充电触点的电压值是否在预设范围内，确定充电盒的供电触点是否处于通讯模式，从而确定充电盒是否需要与无线耳机进行数据交互。对于预设范围的具体范围设置，可以由设计人员自行设置，本实施例对此不做任何限制。
需要说明的是，对于无线耳机检测充电触点的电压值不在预设范围内的情况，可以继续保持充电触点的充电模式，进行充电。
步骤202：启动ble扫描，接收充电盒通过ble广播发送的命令信息；其中，命令信息包括请求数据信息和数据信息。
可以理解的是，本步骤的目的无线耳机可以为在确定充电盒需要与无线耳机进行数据交互后，启动ble扫描，接收充电盒通过ble广播发送的数据。即充电盒在需要与无线耳机进行信息交互时，可以通过将供电触电切换成通讯模式告知无线耳机，并将需要发送的数据和/或需要请求接收的数据对应的信息通过ble广播发送给无线耳机。
其中，命令信息中的请求数据信息可以为充电盒需要从无线耳机接收的数据对应的信息，命令信息中的数据信息可以为充电盒需要向无线耳机发送的数据。
需要说明的是，若接收到的命令信息中包括请求数据信息，无线耳机可以根据该请求数据信息，通过充电触点，向充电盒发送ble扫描命令并通过ble广播向充电盒发送该请求数据信息对应的数据。也就是说，无线耳机可以通过单线连接通知充电盒进行ble扫描，通过ble广播向无线耳机发送请求数据信息对应的数据。具体的，充电盒发送的请求数据信息可以如本实施例所示，通过ble广播发送，也可以通过单线连接发送，本实施例对此不做任何限制。
步骤203：将充电触点由充电模式切换成通讯模式，与充电盒建立单线连接。
可以理解的是，本步骤与步骤202并不存在必然的逻辑顺序，可以先启动ble广播再将充电触点切换成通讯模式，也可以先将充电触点切换成通讯模式再启动ble广播。只要无线耳机可以在确定充电盒需要与无线耳机进行数据交互后，启动ble扫描和将充电触点切换成通讯模式，本实施例对此不 做任何限制。
步骤204：通过充电触点，向充电盒发送状态信息；其中，状态信息包括无线耳机的电量信息和配对信息。
其中，本步骤的目的可以为无线耳机在每次与充电盒建立单线连接后，均通过单线连接向充电盒发送如电量信息和配对信息等无线耳机的状态信息，以方便充电盒了解无线耳机的状态。对于状态信息具体包含的内容可以由设计人员自行设置，可以仅包括电量信息和配对信息，还可以包括其他信息，本实施例对此不做任何限制。
需要说明的是，由于无线耳机的充电触点为通讯模式时，需要避免充电盒的供电触电切换为充电模式，即断开单线连接时，需要先将无线耳机的充电触点切换为充电模式，再将充电盒的供电触电切换为充电模式。对于无线耳机断开与充电盒建立的单线连接的具体方式，可以由设计人员根据实用场景和用户需求自行设置，如无线耳机可以在通过单线连接进行本步骤，或通过单线连接进行本步骤和发送ble扫描命令之后，直接将充电触点切换为充电模式；还可以在将充电触点切换为充电模式之前，通过单线连接向充电盒发送单线连接断开信息，告知充电盒可以将供电触点切换为充电模式。只要可以保证在充电盒的供电触电切换为充电模式之前，将无线耳机的充电触点切换为充电模式，本实施例对此不做任何限制。
本实施例中，本发明实施例通过无线耳机与充电盒之间的单线连接，可以确定无线耳机与充电盒之间的ble通信的广播和扫描顺序，提升了无线耳机与充电盒的数据传输速度，避免了ble通信的广播扫描冲突，提高了充电盒与无线耳机通信的可靠性，提高了用户体验。

步骤302：将供电触点由充电模式切换成通讯模式。
其中，本步骤中充电盒将与无线耳机的充电触点连接的供电触点由充电模式切换成通讯模式的具体方式，可以由设计人员根据供电触点的具体结构对应设置，只要可以保证充电盒的供电触点处于充电模式时可以对无线耳机处于充电模式的充电触点进行供电，充电盒的供电触点处于通讯模式时可以与无线耳机处于通讯模式的充电触点进行信息交互，本实施例对此不做任何限制。
需要说明的是，本实施例所展示的建立单线连接的方法可以为以充电盒为执行主体与无线耳机建立单线连接的方法，具体执行方式可以与上述无线耳机为执行主体的建立单线连接的方法相对应，在此不再赘述。
