背景技术
目前，一副蓝牙耳机的两个耳机之间的信息同步技术主要包括蓝牙技术和磁场耦合技术。但是，蓝牙技术所使用的频率过高，而人体对高频信号的衰减较大，因此，使用蓝牙技术时需要使用较大的发射功率，以便信号“绕着”人脑进行传输，其通信功耗过大。磁场耦合技术需要定向性好的磁芯，这种磁芯的体积一般比较大，会和无线耳机的小型化的设计需求发生冲突。
耳机与充电盒之间的信息同步技术主要包括电力线载波通讯技术和串口通信技术。类似地，电力线载波通讯技术的电路设计过于复杂，并且需要额外的电路芯片。串口通信技术会降低电路连接的可靠性，进而降低了通信质量。此外，电力线载波通信技术和串口通讯技术都需要物理触点，会降低耳机与充电盒之间的连接的可靠性。
因此，本领域急需一种体积小、通信功耗低、结构简单且通信质量和连接可靠性高的耳机或充电盒。

图1是本申请实施例的传输信息的方100的示意性框图。应理解，所述方法100可由便携式设备或者包括所述便携式设备的电子设备执行。为便于理解，下面以所述方法由便携式设备执行为例，对所述方法100进行详细描述。
如图1所示，所述方法100可以包括：
S110，便携式设备可以通过设置于所述便携式设备上的第一耦合电极和对端的第二耦合电极，以电场耦合的方式接收和/或发送信息。
具体地，所述便携式设备获取基带信号；然后基于所述基带信号生成调制信号；再通过所述第一耦合电极和所述第二耦合电极，以电场耦合的方式，接收和/或发送所述调制信号。
以通过所述第一耦合电极和所述第二耦合电极发送调制信号为例，所述便携式设备的发射电路可以在获取基带信号后，基于所述基带信号生成调制信号，并向所述第一耦合电极注入所述调制信号，由此可以通过所述第一耦合电极向所述第二耦合电极发送所述调制信号。
具体地，所述便携式设备将所述调制信号输入到所述第一耦合电极后， 会引起所述第一耦合电极的周围电场发生变化。由于所述第一耦合电极和所述第二耦合电极的距离较近，会使得所述第二耦合电极的周围电场也发生变化。因此，所述对端可以通过所述第二耦合电极感应所述第二电极的周围电场的变化，进而接收所述便携式设备发送的调制信号。或者说，所述第一耦合电极和所述第二耦合电极形成耦合电容，所述便携式设备将所述调制信号输入到所述第一耦合电极后，所述耦合电容的周围电场会发生变化，所述对端可以通过所述第二耦合电极感应所述耦合电容的周围电场的变化，生成交流信号。其中，所述交流信号可以用于传递信号或能量。例如，所述交流信号可以用于传输所述调制信号。
所述便携式设备接收所述对端发送的信息时，所述便携式设备通过所述第一耦合电极和所述第二耦合电极，以电场耦合的方式获取所述对端发送的调制信号后，通过对所述调制信号解调，获取，所述便携式设备能够识别的基带信号。其具体原理与，所述便携式设备向所述对端发送信息的原理类似，为了避免重复，此处不再赘述。
本申请实施例中，所述便携式设备可以基于电场耦合的方式进行通信。所述第一耦合电极和所述第二耦合电极用于组成耦合电容。耦合电容指可以用于耦合的电容。所述耦合可以指将信号从所述第一耦合电极传播到所述第二耦合电极的过程，或者耦合可以指将信号从第二耦合电极传播到所述第一耦合电极的过程。电场耦合可以指由于所述耦合电容的存在而产生的一种耦合方式。
此外，所述耦合电容除了用于耦合之外，还可以用于保证通信质量。以信号从所述第一耦合电极传输至所述第二耦合电极为例，所述第一耦合电极能够尽可能无损耗地将接收到的信号传输至所述第二耦合电极，并去掉不需要的信号。具体地，由于电容具有隔直通交的特性，所述耦合电容不仅能够将交流成分(即待发送的信息)从所述第一耦合电极传输至所述第二耦合电极，而且能够阻隔掺杂在所述交流成分中的直流成分。
而且，通过电场耦合的方式进行通信，能够避免为所述便携式设备设置物理触点，能够增加所述便携式设备的连接可靠性。例如耳机或充电盒之间的连接可靠性。
可选地，所便携式设备为所述第一耦合电极注入的调制信号的调制度和/或信号强度，可以与所述第一耦合电极和所述第二耦合电极相关。例如，所 述调制信号的调制度和/或信号强度，与所述第一耦合电极的电极面积和所述第二耦合电极的电极面积相关；比如所述第一耦合电极的电极面积和所述第二耦合电极的电极面积越大，所述调制信号的调制度和/或信号强度越小。又例如，所述调制信号的调制度和/或信号强度，与所述第一耦合电极的电极形状和所述第二耦合电极的电极形状相关。又例如，所述调制信号的调制度和/或信号强度，与所述第一耦合电极和所述第二耦合电极之间的介质材料有关。比如所述第一耦合电极所在的设备的外壳的材料和所述对端的外壳的材料。
所述第一耦合电极和所述第二耦合电极可以是用导体制作的薄片或薄板，也可以是具有导电特性的实体。所述第一耦合电极和所述第二耦合电极的形状可以是规则形状。例如矩形、椭圆形以及圆形等。所述第一耦合电极和所述第二耦合电极的电极面积可以大于或者等于某一阈值。
可选地，所述第一耦合电极在第一平面的投影面积与所述第二耦合电极在所述第一平面上的投影面积之差小于或等于预设阈值，所述第一平面平行于所述第一耦合电极所在的平面或所述第二耦合电极所在的平面。例如，所述第一耦合电极或所述第二耦合电极为矩形薄片时，所述第一平面为所述矩形薄片的上表面或下表面。本申请实施例中，通过设置使得所述第一耦合电极在所述第一平面的投影面积和所述第二耦合电极在所述第一平面的投影面积之差小于或等于所述预设阈值，可以控制所述第一耦合电极和所述第二耦合电极的尺寸，进而控制所述第一耳机和所述第二耳机的体积。
此外，所述第一耦合电极在第一平面的投影面积与所述第二耦合电极在所述第一平面上的投影面积之差还可以大于某一阈值，以保证所述第一耦合电极和所述第二耦合电极之间的通信质量。
所述第一耦合电极可以正对所述第二耦合电极设置，以最大程度的增加所述第一耦合电极和所述第二耦合电极的感测范围，进而保证所述第一耦合电极和所述第二耦合电极之间的通信质量。例如，所述第一耦合电极的内侧表面可以正对所述第二耦合电极的内侧表面。进一步地，所述第一耦合电极和所述第二耦合电极可以对称设置。例如，所述第一耦合电极和所述第二耦合电极可以轴对称设置，其中所述第一耦合电极和所述第二耦合电极的对称轴可以是所述第一耦合电极所属的便携式设备和所述第二耦合电极所属的对端设备的对称轴。
应理解，本申请实施例中，用于执行所述方法100的主体可以是便携式设备。换句话说，所述方法100可以应用于便携式设备。例如，所述便携式设备可以是无线耳机或者充电盒。又例如，所述便携式设备还可以是电子手表等其他便于携带的电子设备。
以所述方法100应用于一副耳机中的第一耳机为例，所述第一耳机可以通过所述第一耦合电极和所述第二耦合电极，以电场耦合的方式向对端发送信息。例如，所述第一耳机可以通过所述第一耦合电极和所述第二耦合电极，以电场耦合的方式向所述对端发送所述第一耳机的以下信息中的至少一项：
状态信息、电池信息、配对信息以及语音信息。
其中，所述第一耳机的状态信息可以用于表示所述第一耳机的是否与电子设备(例如手机)处于连接状态。所述电池信息可以包括所述第一耳机的电池的参数信息以及所述第一耳机的电池的电量信息。所述配对信息可以用于与电子设备或者耳机建立连接。所述语音信息可以是所述第一耳机的麦克风获取的语音信息。
所述方法100应用于所述第一耳机时，所述对端可以为所述一副耳机中的第二耳机。例如，所述第一耳机为左耳朵佩戴的耳机，所述第二耳机为右耳朵佩戴的耳机。所述对端还可以是所述第一耳机的充电盒。
以所述便携式设备为一副耳机为例，通信的一端为该副耳机的第一耳机且所述对端为该副耳机的第二耳机为例，所述第一耳机接收所述第二耳机发送的信息失败时，说明该副耳机不是佩戴于一个人，则可以控制所述第一耳机独立上传语音信息。这种情况下，所述第二耳机也可以独立上传语音信息。例如，用户正在使用所述第一耳机打电话，且所述第一耳机接收不到所述第二耳机发送的信息时，可以控制所述第一耳机独立上传语音信息。
换句话说，通过所述第一耳机是否能够收到所述第二耳机发送的信息，能够确定所述第一耳机和所述第二耳机是否由一个人佩戴；当所述第一耳机和所述第二耳机不是由一个人佩戴时，所述第一耳机和所述第二耳机均可以独立上传语音信息。例如，当两个人分别使用所述第一耳机和所述第二耳机时，因为一副耳机的左右两个耳机可以独立上传语音信息，所以这两个人可以使用一副耳机和第三方进行多方通信。例如三方电话会议。
具体地，由于人体的主要成分为是水，因此，人体是一种高介电常数的介质(约80)，当同一个人的两个耳朵分别戴上所述第一耳机和所述第二耳 机，且所述第一耳机的第一耦合电极和所述第二耳机的第二耦合电极均和人体皮肤接触时，相当于在所述第一耦合电极和所述第二耦合电极之间插入一个具有非常高的介电常数的介质，即所述第一耳机和所述第二耳机之间的距离等效于缩短约80倍。
换句话说，所述第一耦合电极和所述第二耦合电极均与人体皮肤接触时，相当于所述第一耦合电极等效强耦合所述第二耦合电极，能够有效降低通信打码频率。例如，所述第一耦合电极和所述第二耦合电极不与人体皮肤接触时，其工作频率需要位于1-10Mhz之间，所述第一耦合电极和所述第二耦合电极与人体皮肤接触时，其工作频率可以为KHz级别的频率。
基于这个原理，本申请实施例中，所述第一耳机和所述第二耳机采用电场耦合的方式进行通信时，不仅对所述第一耦合电极和所述第二耦合电极的要求较低，而且还能够对所述第一耳机和所述第二耳机是否由一个人佩戴进行检测。具体地，所述第一耳机和所述第二耳机之间信息交互失败时，确定所述第一耳机和所述第二耳机不是由一个人佩戴，此时可以控制所述第一耳机和所述第二耳机分别独立上传语音信息，进而实现多方通信。进一步地，通过所述第一耳机和所述第二耳机独立上传语音信息，可以有效保护使用者的隐私。
应理解，本申请实施例中的一副耳机可以是包括用于左耳佩戴的耳机和用于右耳佩戴的耳机，即左耳机和右耳机。所述左耳机和所述右耳机可以通过配对的方式组成一副耳机。例如，所述一副耳机可以为头戴式耳机时，所述第一耳机和所述第二耳机可以分别为所述头戴式耳机的两个耳罩所在的部分。又例如，所一副耳机为挂耳式耳机时，所述第一耳机和所述第二耳机分别为所述挂耳式耳机的挂在两只耳朵上的部分。又例如，所述一副耳机为半入耳式耳机或者全入耳式耳机时，所述第一耳机和所述第二耳机分别为塞入两只耳朵的部分。
还应理解，本申请实施例的所述一副耳机的两个耳机可以是物理上分开的左耳机和右耳机，也可以是物理上相连接的左耳机和右耳机，本申请实施例对此不做具体限定。
以所述方法100应用于充电盒为例，例如第三耳机的充电盒。所述充电盒可以通过所述第一耦合电极和所述第二耦合电极，以电场耦合的方式向对端发送信息。例如，所述充电盒可以通过所述第一耦合电极和所述第二耦合 电极，以电场耦合的方式向所述对端发送所述第一耳机的以下信息中的至少一项：
状态信息、电池信息以及语音信息；
其中，所述语音信息为所述充电盒从与所述充电盒连接的终端设备获取的信息。所述充电盒的状态信息可以用于表示所述充电盒的是否处于可充电充电，例如，所述充电盒是否剩余有用于容纳所述第三耳机的槽或孔。所述电池信息可以包括所述充电盒的电池的参数信息以及所述充电盒的电池的电量信息。
所述方法100应用于所述充电盒时，所述对端可以为所述第三耳机，也可以是能够使用所述充电盒进行充电的其它电子设备。
上文结合图1对本申请实施例的便携式设备传输信息的方法进行了说明，下面结合图2至图6对本申请实施例的通信装置和包括所述通信装置的电子设备进行说明。
图2是本申请实施例的通信装置210的示意性框图。
如图2所示，所述通信装置210可以包括第一发射电路201、第一接收电路202以及第一耦合电极203，所述第一发射电路201和所述第一接收电路202分别与所述第一耦合电极相连。其中，所述第一发射电路201用于通过所述第一耦合电极203和对端的第二耦合电极，以电场耦合的方式向所述对端发送信息，所述第一接收电路202用于通过所述第一耦合电极203和所述第二耦合电极，以电场耦合的方式接收所述对端发送的信息。
具体地，所述第一发射电路201可以用于获取基带信号；然后基于所述基带信号生成调制信号；最后通过所述第一耦合电极203和所述第二耦合电极，以电场耦合的方式，向所述对端发送所述调制信号。
可选地，所述调制信号的调制度和/或信号强度，与所述第一耦合电极203和所述第二耦合电极相关。
