Description

一种头戴式无线耳机及其通信方法 技术领域
本申请实施例涉及通信领域，尤其涉及一种头戴式无线耳机及其通信方法。
背景技术
随着通信技术的发展，耳机成为人们生活中不可缺少的产品。目前，头戴式无线耳机因适合高清音乐播放，是各类音乐爱好者欣赏音乐的首选设备。
如图1所示的一种头戴式蓝牙耳机，该头戴式蓝牙耳机包括一个蓝牙芯片，以及和该蓝牙芯片相耦合的射频天线，该蓝牙芯片和射频天线位于头戴式无线耳机的其中一个耳机中。
由于该头戴式无线耳机中，射频天线位于一个耳机中，另一个耳机中无射频天线，因此天线的覆盖范围较小，方向局限性较大，导致用户体验较差。例如，当蓝牙芯片位于用户的左耳侧，手机位于用户的右口袋，则蓝牙信号要穿过人头及人体，信号衰减巨大，导致头戴式无线耳机的丢包率较高，用户体验较差。
发明内容
本申请实施例提供一种头戴式无线耳机及其通信方法，能够降低头戴式无线耳机的丢包率，提升用户体验。
为达到上述目的，本申请实施例采用如下技术方案：
本申请实施例的第一方面，提供一种头戴式无线耳机，该头戴式无线耳机包括：第一耳机，包括：第一短距无线通信芯片以及第一射频天线，所述第一短距无线通信芯片与所述第一射频天线相耦合；第二耳机，包括：第二短距无线通信芯片以及第二射频天线；所述第二短距无线通信芯片与所述第二射频天线相耦合；数据总线，分别连接所述第一短距无线通信芯片与所述第二短距无线通信芯片，用于提供所述第一短距无线通信芯片与所述第二短距无线通信芯片之间通信所需的物理链路。基于本方案，通过在头戴式无线耳机的两个耳机中分别设置短距无线通信芯片和射频天线，从而每个短距无线通信芯片可以通过与其耦合的射频天线接收数据，确保头戴式无线耳机的覆盖范围较大。而且通过在两个耳机中的短距无线通信芯片之间设置数据总线，使得两个短距无线通信芯片之间可以通过该数据总线交互数据，因此能够释放一部分空口资源，降低头戴式无线耳机的丢包率，提升用户体验。
可选的，上述数据总线可以设置在连接第一耳机和第二耳机的机械结构之中。
可选的，本申请实施例中的短距无线通信芯片可以包括但不限于蓝牙芯片、绿牙芯片、ZigBee芯片、近场通信(near field communication，NFC)芯片或者未来衍生的其他用于短距离无线通信的芯片，本申请实施例对于短距无线通信芯片的具体类型并不限定。
结合第一方面，在一种可能的实现方式中，上述第一短距无线通信芯片用于：通过第一射频天线接收来自终端设备的数据包；在未成功接收该数据包的情况下，通过 数据总线向第二短距无线通信芯片发送第一信息，以请求第二短距无线通信芯片转发数据包；该第一信息用于指示第一短距无线通信芯片未成功接收该数据包。基于本方案，在一个短距无线通信芯片未成功接收数据包的情况下，该未成功接收数据包的短距无线通信芯片可以通过数据总线请求另一短距无线通信芯片转发数据包，从而即使有一个短距无线通信芯片未成功接收数据包，只要另一个短距无线通信芯片成功接收数据包，该成功接收数据包的短距无线通信芯片可以向未成功接收数据包的短距无线通信芯片转发其成功接收的数据包，不需要终端设重传数据包，因此能够提升头戴式无线耳机接收数据包的成功率，降低头戴式无线耳机的丢包率，提升用户体验。
可选的，上述第一短距无线通信芯片可以为主芯片，也可以为从芯片。当第一短距无线通信芯片为主芯片时，第二短距无线通信芯片为从芯片。当第一短距无线通信芯片为从芯片时，第二短距无线通信芯片可以为主芯片。上述主芯片可以为左耳机中的芯片，也可以为右耳机中的芯片。
结合第一方面和上述可能的实现方式，在另一种可能的实现方式中，上述第二短距无线通信芯片，用于：通过上述第二射频天线接收来自上述终端设备的上述数据包；在成功接收该数据包的情况下，响应上述第一信息，通过上述数据总线向上述第一短距无线通信芯片传输其成功接收的数据包。基于本方案，成功接收数据包的短距无线通信芯片通过数据总线向未成功接收数据包的短距无线通信芯片转发其成功接收的数据包，由于数据总线重传数据包，相对于通过空口重传数据的传输速度快，因此能够降低终端设备和头戴式无线耳机的功耗。
可以理解的，本申请提供的方案中，如果只有一个短距无线通信芯片成功接收数据包，成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发数据包，终端设备无需重传数据包。只有在两个短距无线通信芯片均接收数据包失败的情况下，终端设备才会重传数据包。因此，能够提高头戴式无线耳机接收数据包的成功率。

结合第一方面和上述可能的实现方式，在另一种可能的实现方式中，上述第一短距无线通信芯片为主芯片，上述第二短距无线通信芯片为从芯片；第一短距无线通信芯片，还用于在第一短距无线通信芯片成功接收上述数据包的情况下，向终端设备发送第三信息，该第三信息用于指示数据包接收成功。基于本方案，在主芯片成功接收数据包的情况下，不论从芯片是否成功接收数据包，主芯片可以直接通知终端设备数 据包接收成功。该实现方式与前一实现方式的区别在于，该实现方式中由于主芯片成功接收数据包，因此主芯片可以直接通知终端设备数据包接收成功。而前一实现方式中，由于主芯片接收数据包失败，而从芯片接收数据包成功，因此主芯片是在获知从芯片接收数据包成功以后，再通知终端设备数据包接收成功。
结合第一方面和上述可能的实现方式，在另一种可能的实现方式中，上述第一短距无线通信芯片，还用于向第二短距无线通信芯片发送第四信息，该第四信息用于指示第一短距无线通信芯片成功接收数据包。基于本方案，第一短距无线通信芯片可以通过数据总线告知第二短距无线通信芯片自己是否成功接收到来自终端设备的数据包，以实现双耳同步。
可选的，本申请实施例中无论第一短距无线通信芯片和第二短距无线通信芯片是否成功接收终端的数据包，第一短距无线通信芯片和第二短距无线通信芯片都可以通过数据总线告知对方自己是否成功接收到来自终端设备的数据包，以实现双耳间的同步。

可选的，第一短距无线通信芯片解码的数据包可以是其从终端设备成功接收的数据包，也可以是第二短距无线通信芯片转发给它的数据包。第二短距无线通信芯片解码的数据包可以是其从终端设备成功接收的数据包，也可以是第一短距无线通信芯片转发给它的数据包。
结合第一方面和上述可能的实现方式，在另一种可能的实现方式中，上述第一短距无线通信芯片为主芯片，上述第二短距无线通信芯片为从芯片；第二短距无线通信芯片，还用于在第二短距无线通信芯片未成功接收来自终端设备的数据包的情况下，通过数据总线向第一短距无线通信芯片发送第五信息；该第五信息用于指示第二短距无线通信芯片未成功接收数据包；第一短距无线通信芯片，用于在第一短距无线通信芯片未成功接收数据包的情况下，响应第五信息，向终端设备发送第六信息，该第六信息用于指示终端设备重传数据包。基于本方案，在第一短距无线通信芯片和第二短距无线通信芯片均未成功接收数据包的情况下，主芯片才会指示终端设备重传数据包。也就是说，本申请实施例中的方案只要有至少一个短距无线通信芯片成功接收数据包，终端设备就不需要重传数据包，因此能够提高头戴式无线耳机接收数据包的成功率。而且两个短距无线通信芯片之间通过数据总线交互，而不需要通过空口交互，能够节省一部分空口资源，进一步降低头戴式无线耳机的丢包率，提升用户体验。

目前，头戴式无线耳机因适合高清音乐播放，是各类音乐爱好者欣赏音乐的首选设备。但是，现有的头戴式无线耳机一般为单蓝牙芯片的蓝牙耳机。
示例性的，图1为一种单蓝牙芯片的头戴式无线耳机，如图1所示，该头戴式无线耳机包括一个蓝牙芯片，以及和该蓝牙芯片相耦合的射频天线，该蓝牙芯片和射频天线位于头戴式无线耳机的一侧，头戴式无线耳机的两个耳机中的扬声器分别通过线缆与该蓝牙芯片耦合连接。
但是，由于图1所示的头戴式无线耳机中，射频天线位于一个耳机中，另一个耳机中无射频天线，因此天线的覆盖范围较小，方向局限性较大，导致用户体验较差。例如，当蓝牙芯片位于用户的左耳侧，手机位于用户的右口袋，则蓝牙信号要穿过人头及人体，信号衰减巨大，导致头戴式无线耳机的丢包率较高，用户体验较差。
为了提升单蓝牙芯片的头戴式无线耳机的覆盖范围，本申请实施例提供一种头戴式无线耳机，该头戴式无线耳机可以在两个耳机中分别设置射频天线，并将两个耳机的天线通过天线同轴线连接。
例如，如图2所示的一种头戴式无线耳机，该头戴式无线耳机包括耳机1和耳机2，耳机1包括一个蓝牙芯片，以及与该蓝牙芯片相耦合的射频天线1，耳机2包括射频天线2，射频天线2通过天线同轴线与蓝牙芯片相耦合，该天线同轴线穿过头戴式耳机的连接部分。耳机1和耳机2中的扬声器分别通过线缆与该蓝牙芯片相耦合。
但是，图2所示头戴式无线耳机中因天线同轴线穿过头戴式耳机的连接部分，而该连接部分在用户使用过程中会存在不同程度的弯曲，造成天线同轴线容易断裂，无法保证天线正常接收数据，可能造成用户体验较差。而且由于天线同轴线过长，造成天线插损过大，天线增益较差，导致天线接收的信号较差。
为了提升头戴式无线耳机的覆盖范围，本申请实施例还提供一种头戴式无线耳机，该头戴式无线耳机可以在两个耳机中分别设置蓝牙芯片和射频天线。
例如，如图3所示的一种头戴式无线耳机，该头戴式无线耳机包括耳机1和耳机2，耳机1包括蓝牙芯片1，以及与该蓝牙芯片1相耦合的射频天线1，耳机2包括蓝牙芯片2，以及与该蓝牙芯片2相耦合的射频天线2。可选的，耳机1和耳机2还可以包括扬声器，耳机1中的扬声器与蓝牙芯片1相耦合，耳机2中的扬声器与蓝牙芯片2相耦合。
虽然图3所示的蓝牙耳机覆盖范围较大，但是由于两个耳机在大多数场景下，接收信号是不平衡的，导致两个耳机的丢包会互相影响。例如，当手机位于用户的右口袋，由于右耳距离手机较近，信号质量参数较好，右耳机能够接收手机发送的音频数据包。但是，右耳机接收到音频数据包后不能直接播放，需要等左耳机收到该音频数据包后一起播放，然而，由于左耳机距离手机较远，信号质量参数较差，可能接收不到手机发送的音频数据包，左耳机的丢包会对右耳机造成影响，导致左耳机和右耳机都不能播放音频数据。而且，由于左耳机和右耳机的蓝牙芯片不仅通过空口接收手机发送的音频数据包，而且左右耳机之间还要通过空口确认对方是否收到音频数据包，可能导致空口速率不够，影响音频数据包的传输。
为了降低头戴式无线耳机的丢包率，提升用户体验。本申请实施例还提供一种头戴式无线耳机，该头戴式无线耳机包括第一耳机、第二耳机和数据总线；第一耳机包括：第一短距无线通信芯片以及第一射频天线，该第一短距无线通信芯片与第一射频天线相耦合。第二耳机包括：第二短距无线通信芯片以及第二射频天线，第二短距无线通信芯片与第二射频天线相耦合。数据总线分别连接第一短距无线通信芯片与第二短距无线通信芯片，用于提供第一短距无线通信芯片与第二短距无线通信芯片之间通信所需的物理链路。
上述第一耳机可以为左耳机也可以为右耳机。当第一耳机为左耳机时，第二耳机为右耳机。当第一耳机为右耳机时，第二耳机为左耳机。
可选的，上述第一耳机可以包括一个或多个第一射频天线，第二耳机可以包括一个或多个第二射频天线。
可选的，上述第一短距无线通信芯片和第二短距无线通信芯片可以包括但不限于蓝牙芯片、绿牙芯片、ZigBee芯片、近场通信(near field communication，NFC)芯片或者未来衍生的其他用于短距离无线通信的芯片，本申请实施例对于短距无线通信芯片的具体类型并不限定，下述实施例以短距无线通信芯片为蓝牙芯片为例进行说明。
可选的，上述数据总线可以设置在连接第一耳机和第二耳机的机械结构之中。例如，头戴式无线耳机还可以包括弧形支撑架，第一耳机和第二耳机通过该弧形支撑架连接，第一短距无线通信芯片与第二短距无线通信芯片之间的数据总线可以设置于该弧形支撑架中。本申请实施例对于第一短距无线通信芯片和第二短距无线通信芯片之间的数据总线的具体设置位置并不限定，在此仅是示例性说明。
可选的，上述数据总线包括串行外设接口(serial peripheral interface，SPI)总线、队列串行外设接口(queued serial peripheral interface，QSPI)总线、双串行外设接口(dual serial peripheral interface，DSPI)总线、通用异步收发器(universal asynchronous  receiver/transmitter，UART)总线、或集成电路总线(inter-integrated circuit bus，I2C)。本申请实施例对于数据总线的具体类型并不限定。
可选的，第一耳机还可以包括第一扬声器，第一扬声器与第一短距无线通信芯片相耦合。第一短距无线通信芯片，用于解码数据包，并通过第一扬声器播放解码的数据包。
可选的，第二耳机还可以包括第二扬声器，第二扬声器与第二短距无线通信芯片相耦合。第二短距无线通信芯片，用于解码数据包，并通过第二扬声器播放解码的数据包。
例如，如图4所示的一种头戴式无线耳机，该头戴式无线耳机包括耳机1、耳机2和数据总线，耳机1包括蓝牙芯片1，以及与蓝牙芯片1分别耦合的射频天线1和扬声器1，耳机2包括蓝牙芯片2，以及与蓝牙芯片2分别耦合的射频天线2和扬声器2。耳机1和耳机2通过弧形支撑架连接，蓝牙芯片1与蓝牙芯片2之间通过数据总线连接，该数据总线可以设置于该弧形支撑架中。
第一短距无线通信芯片，用于通过第一射频天线接收来自终端设备的数据包。
第二短距无线通信芯片，用于通过第二射频天线接收来自终端设备的数据包。
可选的，第一短距无线通信芯片和第二短距无线通信芯片接收的数据包可以为音频数据包。第一短距无线通信芯片和第二短距无线通信芯片可以通过空口接收来自终端设备的音频数据包。
例如，如图4所示，蓝牙芯片1可以通过射频天线1接收来自终端设备的数据包1，蓝牙芯片2可以通过射频天线2接收来自终端设备的数据包1。
实际应用中，第一短距无线通信芯片和第二短距无线通信芯片可能均未成功接收终端设备发送的数据包，也可能均成功接收终端设备发送的数据包，还有可能其中一个短距无线通信芯片成功接收终端设备发送的数据包，另一个短距无线通信芯片未成功接收终端设备发送的数据包。下面结合不同场景，以第一短距无线通信芯片为主芯片，第二短距无线通信芯片为从芯片为例，对第一短距无线通信芯片与第二短距无线通信芯片的功能进行详细介绍。
可选的，主芯片可以为左耳机中的芯片，也可以右耳机中的芯片，本申请实施例对此并不限定。当主芯片为左耳机中的短距无线通信芯片时，右耳机中的短距无线通信芯片为从芯片。当主芯片为右耳机中的短距无线通信芯片时，左耳机中的短距无线通信芯片为主芯片。
第一种场景，第一短距无线通信芯片未成功接收数据包，第二短距无线通信芯片成功接收数据包。
第一短距无线通信芯片，还用于通过数据总线向第二短距无线通信芯片发送第一信息，以请求第二短距无线通信芯片转发其成功接收的数据包。该第一信息用于指示第一短距无线通信芯片未成功接收数据包。
第二短距无线通信芯片，还用于响应该第一信息，通过数据总线向第一短距无线通信芯片转发其成功接收的数据包。
例如，如图4所示，以蓝牙芯片1为主芯片，蓝牙芯片2为从芯片为例。在蓝牙芯片1未成功接收数据包1，蓝牙芯片2成功接收数据包1的情况下，蓝牙芯片1向 蓝牙芯片2发送第一信息，通知蓝牙芯片2蓝牙芯片1未成功接收数据包1，以请求蓝牙芯片2转发其成功接收的数据包1。蓝牙芯片2响应该第一信息，通过数据总线将其成功接收的数据包1转发给蓝牙芯片1。
第二短距无线通信芯片，还用于通过数据总线向第一短距无线通信芯片发送第二信息。该第二信息用于指示第二短距无线通信芯片成功接收数据包。
第一短距无线通信芯片，还用于响应该第二信息，向终端设备发送第三信息。该第三信息用于指示数据包接收成功。
可选的，上述第三信息可以为肯定应答(Acknowledgement，ACK)。
例如，如图4所示，以蓝牙芯片1为主芯片，蓝牙芯片2为从芯片为例。在蓝牙芯片1未成功接收数据包1，蓝牙芯片2成功接收数据包1的情况下，蓝牙芯片2向蓝牙芯片1发送第二信息，通知蓝牙芯片1蓝牙芯片2成功接收数据包1。蓝牙芯片1响应该第二信息，通过终端设备数据包接收成功。
本申请实施例在主芯片未成功接收数据包，而从芯片成功接收数据包的情况下，从芯片可以通过数据总线告知主芯片其成功接收数据包，主芯片获知从芯片成功接收数据包之后，可以通过空口通知终端数据包接收成功。
第二种场景，第一短距无线通信芯片成功接收数据包，第二短距无线通信芯片未成功接收数据包。
第二短距无线通信芯片，还用于通过数据总线向第一短距无线通信芯片发送第五信息，以请求第一短距无线通信芯片转发上述数据包。该第五信息用于指示第二短距无线通信芯片未成功接收数据包。
第一短距无线通信芯片，还用于响应第五信息，通过数据总线向第二短距无线通信芯片传输数据包。
例如，如图4所示，以蓝牙芯片1为主芯片，蓝牙芯片2为从芯片为例。在蓝牙芯片1成功接收数据包2，蓝牙芯片2未成功接收数据包2的情况下，蓝牙芯片2向蓝牙芯片1发送第五信息，通知蓝牙芯片1蓝牙芯片2未成功接收数据包2，以请求蓝牙芯片1转发其成功接收的数据包2。蓝牙芯片1响应该第五信息，通过数据总线将其成功接收的数据包2转发给蓝牙芯片2。
第一短距无线通信芯片还用于向终端设备发送第三信息，该第三信息用于指示数据包接收成功。
上述第一种场景和第二种场景主芯片都会通知终端设备数据包接收成功。第二种场景与第一种场景的区别在于，第二种场景中由于主芯片成功接收数据包，因此主芯片可以直接通知终端设备数据包接收成功。而第一种场景中，由于主芯片接收数据包失败，而从芯片接收数据包成功，因此主芯片是在获知从芯片接收数据包成功以后，再通知终端设备数据包接收成功。
可选的，上述第二种场景中，第一短距无线通信芯片还可以向第二短距无线通信芯片发送第四信息。该第四信息用于指示第一短距无线通信芯片成功接收数据包。
上述第一种场景和第二种场景中，在只有一个短距无线通信芯片成功接收数据包的情况下，该成功接收数据包的短距无线通信芯片可以通过数据总线向另一未成功接收数据包的短距无线通信芯片转发其接收成功的数据包。该成功接收数据包的短距无 线通信芯片可以为主芯片，也可以为从芯片，本申请对此并不限定。
可以理解的，本实施例通过在两个短距无线通信芯片之间设置数据总线，两个短距无线通信芯片之间可以通过数据总线交互，而不是通过空口交互，因此能够释放一部分空口资源，降低头戴式无线耳机的丢包率。而且本实施例在一个短距无线通信芯片未成功接收数据包的情况下，成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发其成功接收的数据包，由于数据总线的传输速度较快，因此能够提高两个短距无线通信芯片接收数据包的成功率，降低终端设备和头戴式无线耳机的功耗。
第三种场景，第一短距无线通信芯片成功接收数据包，第二短距无线通信芯片成功接收数据包。
第一短距无线通信芯片，还用于向终端设备发送第三信息，该第三信息用于指示数据包接收成功。
在该场景中，由于主芯片成功接收数据包，主芯片可以直接通知终端设备数据包接收成功。
可选的，第二短距无线通信芯片还可以向第一短距无线通信芯片发送第二信息，以通知第一短距无线通信芯片，第二短距无线通信芯片成功接收上述数据包。
第四种场景，第一短距无线通信芯片未成功接收数据包，第二短距无线通信芯片未成功接收数据包。
第二短距无线通信芯片，还用于通过数据总线向第一短距无线通信芯片发送第五信息。该第五信息用于指示第二短距无线通信芯片未成功接收数据包。
第一短距无线通信芯片，还用于响应第五信息，向终端设备发送第六信息。该第六信息用于指示终端设备重传数据包。
可选的，第六信息可以为否定应答(Negative Acknowledgement，NACK)。
在该场景中，由于主芯片和从芯片均未成功接收数据包，因此主芯片通过数据总线获知从芯片也未成功接收数据包后，可以通过空口通知终端设备重传数据包。
可选的，实际应用中，不管在上述哪种场景中，第一短距无线通信芯片和第二短距无线通信芯片都可以通过数据总线告知对方自己是否成功接收到来自终端设备的数据包，以实现双耳同步。比如，如图4所示，蓝牙芯片1可以通过数据总线通知蓝牙芯片2，蓝牙芯片1成功或未成功接收数据包。蓝牙芯片2通过数据总线通知蓝牙芯片1，蓝牙芯片2成功或未成功接收数据包。从而使得两个蓝牙芯片可以获知对方是否成功接收到来自终端设备的数据包，实现双耳间的同步。
可选的，上述第一短距无线通信芯片包括第一音频处理器、第一射频电路和第一物理接口，第一音频处理器分别与第一射频电路和第一物理接口相耦合，第一射频电路与第一射频天线相耦合。第二短距无线通信芯片包括第二音频处理器、第二射频电路和第二物理接口，第二音频处理器分别与第二射频电路和第二物理接口相耦合，第二射频电路与第二射频天线相耦合，第一物理接口与第二物理接口通过数据总线相耦合。

第二音频处理器，用于通过第二射频电路和第二射频天线与终端设备之间传输数据，通过第二物理接口和数据总线与第一短距无线通信芯片之间传输数据。
例如，如图5所示，以第一短距无线通信芯片和第二短距无线通信芯片为蓝牙芯片，第一音频处理器和第二音频处理器为数字信号处理器(digital signal processing，DSP)为例。第一蓝牙芯片包括第一蓝牙(bluetooth，BT)核和第一DSP，第一BT核和第一DSP之间的数据通过进程间通信(inter-process communication，IPC)的方式进行交互。第一BT核包括射频电路1和物理接口1，第一DSP分别与射频电路1和物理接口1相耦合，射频电路1与射频天线1相耦合。第二蓝牙芯片可以包括第二BT核和第二DSP，第二BT核包括射频电路2和物理接口2，第二DSP分别与射频电路2和物理接口2相耦合，射频电路2与射频天线2相耦合。物理接口1与物理接口2通过数据总线连接，物理接口1和物理接口2可以为SPI、UART或I2C等接口。本申请实施例对于音频处理器的具体类型并不限定，该音频处理器可以为任一能够对音频数据包进行解码的处理器，图5仅以音频处理器为DSP为例进行示意。DSP包括的业务模块和算法模块用于对音频数据包进行解码处理。
需要说明的是，第一蓝牙芯片和第二蓝牙芯片的电路结构可以完全相同，也可以不完全相同，本申请实施例对于第一蓝牙芯片和第二蓝牙芯片的具体结构并不限定，图5仅是示例性说明。
可以理解的，本实施例通过在第一短距无线通信芯片与第二短距无线通信芯片之间设置数据总线，两个短距无线通信芯片可以通过数据总线交互，并且在一个短距无线通信芯片未成功接收到数据包的情况下，另一个成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发其成功接收的数据包。本实施例中两个短距无线通信芯片之间是通过数据总线交互的，而不是通过空口交互，因此能够释放一部分空口资源，降低头戴式无线耳机的丢包率。而且本实施例两个短距无线通信芯片之间通过数据总线转发数据包，传输速度较快，能够提高两个短距无线通信芯片接收数据包的成功率，降低终端设备和头戴式无线耳机的功耗。
例如，以手机距离左耳较近，距离右耳较远，左耳机单次接收数据包的成功率为80％，右耳机单次接收数据包的成功率为60％为例。对于图1所示的单蓝牙芯片的头戴式无线耳机，如果单蓝牙芯片位于头戴式无线耳机的左耳侧，那么该单蓝牙芯片的头戴式无线耳机接收数据包的成功率为80％。对于图3所示的头戴式无线耳机，在两个耳机均成功接收数据包的情况下，才能正常播放音频数据，即该双蓝牙芯片的头戴式无线耳机接收数据包的成功率为80％*60％＝48％。对于图4所示的头戴式无线耳机，只有在两个耳机均未成功接收到数据包的情况下，才需要终端设备重传该数据包，因此该头戴式无线耳机接收数据包的成功率为1-(1-80％)*(1-60％)＝88％。因此，图4所示头戴式无线耳机，能够提高接收数据包的成功率。
再例如，以手机距离右耳较近，距离左耳较远，左耳机单次接收数据包的成功率为60％，右耳机单次接收数据包的成功率为80％为例。对于图1所示的单蓝牙芯片的头戴式无线耳机，如果单蓝牙芯片位于头戴式无线耳机的左耳侧，那么该单蓝牙芯片的头戴式无线耳机接收数据包的成功率为60％。对于图3所示的头戴式无线耳机，在两个耳机均成功接收数据包的情况下，才能正常播放音频数据，即该双蓝牙芯片的头 戴式无线耳机接收数据包的成功率为80％*60％＝48％。对于图4所示的头戴式无线耳机，只有在两个耳机均未成功接收到数据包的情况下，才需要终端设备重传该数据包，因此该头戴式无线耳机接收数据包的成功率为1-(1-80％)*(1-60％)＝88％。因此，图4所示的头戴式无线耳机，能够提高接收数据包的成功率。
可选的，本申请实施例中第一短距无线通信芯片和第二短距无线通信芯片不仅可以通过数据总线传输上述第一信息、第二信息、第四信息和第五信息，还可以传输除上述第一信息、第二信息、第四信息和第五信息以外的其他信息。例如，第一短距无线通信芯片和第二短距无线通信芯片可以通过数据总线传输耳机的音量、统计数据、信号质量参数、日志、时间戳等信息。
本实施例提供的头戴式无线耳机，通过设置两个短距无线通信芯片，而且这两个短距无线通信芯片可以通过数据总线进行交互，因此能够释放一部分空口资源，降低数据包的重传次数，降低终端设备及头戴式无线耳机的功耗。在一个短距无线通信芯片未成功接收到数据包的情况下，另一个成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发其成功接收的数据包，能够提升头戴式无线耳机接收数据包的成功率，降低头戴式无线耳机的丢包率，提升用户体验。

可以理解的，本实施例提供的短距无线通信芯片，可以通过数据总线与另一短距无线通信芯片交互，即两个短距无线通信芯片之间是通过数据总线交互，而不是通过空口交互，因此能够释放一部分空口资源，降低丢包率。而且本实施例在一个短距无线通信芯片未成功接收数据包的情况下，可以向另一成功接收数据包的短距无线通信芯片请求转发数据包，成功接收数据包的短距无线通信芯片可以通过数据总线转发数据包，传输速度较快，能够提高短距无线通信芯片接收数据包的成功率，降低终端设备和芯片的功耗。
结合图4至图6，本申请实施例还提供一种头戴式无线耳机的通信方法，该头戴式无线耳机可以为上述图4所示的头戴式无线耳机，若第一短距无线通信芯片为主芯片，第二短距无线通信芯片为从芯片，主芯片未成功接收数据包，从芯片成功接收数据包，如图7所示，该通信方法可以包括以下步骤：

可选的，上述第二射频天线接收信号的信号质量参数包括参考信号接收功率RSRP、参考信号接收质量RSRQ、接收信号强度指示RSSI、丢包率PER，以及信号与干扰加噪声比SINR中的任意一种或多种。

可选的，第一短距无线通信芯片确定目标第一射频天线的信号质量参数与第二短距无线通信芯片确定目标第二射频天线的信号质量参数可以相同，也可以不同，本申请实施例对此并不限定。
可以理解的，第二短距无线通信芯片通过在多个第二射频天线中确定目标第二射频天线，并通过该目标第二射频天线接收来自终端设备的数据包，能够提高头戴式无线耳机接收信号的成功率。
可选的，实际应用中，终端设备发送数据包时，有可能第一短距无线通信芯片先接收该数据包，第二短距无线通信芯片后接收该数据包。也有可能第二短距无线通信芯片先接收该数据包，第一短距无线通信芯片后接收该数据包。还有可能第一短距无线通信芯片和第二短距无线通信芯片同时接收该数据包。本申请实施例对此并不限定。
S703、在第一短距无线通信芯片未成功接收数据包的情况下，第一短距无线通信芯片通过数据总线向第二短距无线通信芯片发送第一信息，以请求第二短距无线通信芯片转发数据包。
该第一信息用于指示第一短距无线通信芯片未成功接收数据包。
可选的，第一短距无线通信芯片可以为左耳机中的芯片，也可以为右耳机中的芯片。当第一短距无线通信芯片为左耳机中的芯片时，第二短距无线通信芯片为右耳机中的芯片。当第一短距无线通信芯片为右耳机中的芯片时，第二短距无线通信芯片为左耳机中的芯片。
S704、第二短距无线通信芯片响应第一信息，通过数据总线向第一短距无线通信 芯片传输其成功接收的数据包。
可以理解的，本实施例中，在一个短距无线通信芯片未成功接收到数据包的情况下，该未成功接收到数据包的短距无线通信芯片可以向另一成功接收数据包的短距无线通信芯片请求转发数据包，该成功接收到数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发数据包，从而能够提升头戴式无线耳机接收数据包的成功率，降低头戴式无线耳机的丢包率，提升用户体验。
可选的，上述步骤S701-S704之后还可以包括S705-S706。
S705、第二短距无线通信芯片通过数据总线向第一短距无线通信芯片发送第二信息。
该第二信息用于指示第二短距无线通信芯片成功接收数据包。
S706、第一短距无线通信芯片响应第二信息，向终端设备发送第三信息。
该第三信息用于指示数据包接收成功。
需要说明的是，本申请对于图7所示的步骤S701-S706的执行顺序并不进行限定，图7仅是示例性说明。
本申请实施例提供的通信方法，在只有一个短距无线通信芯片成功接收数据包的情况下，成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片转发其接收的数据包，终端设备无需重传数据包，因此，能够降低头戴式无线耳机的丢包率，提升用户体验。而且两个短距无线通信芯片之间通过数据总线交互，而不是通过空口交互，能够释放一部分空口资源，进一步降低头戴式无线耳机的丢包率，提升用户体验。
本申请实施例还提供一种头戴式无线耳机的通信方法，如图8所示，若第一短距无线通信芯片为主芯片，第二短距无线通信芯片为从芯片，主芯片成功接收数据包，从芯片未成功接收数据包，在上述步骤S701-S702之后还可以包括以下步骤：
S707、在第二短距无线通信芯片未成功接收数据包的情况下，第二短距无线通信芯片通过数据总线向第一短距无线通信芯片发送第五信息，以请求第一短距无线通信芯片转发数据包。
该第五信息用于指示第二短距无线通信芯片未成功接收数据包。

S709、第一短距无线通信芯片向终端设备发送第三信息。
该第三信息用于指示数据包接收成功。
在本实施例中，如果主芯片成功接收数据包，那么无论从芯片是否成功接收数据包，主芯片都可以通知终端设备数据包接收成功。如果从芯片未成功接收数据包，从芯片可以请求主芯片转发数据包，从而实现主从芯片均成功接收数据包，播放音频数据。
可选的，本申请图7和图8所示的实施例中，只要有一个短距无线通信芯片成功接收终端设备发送的数据包，主芯片都会通知终端设备数据包接收成功。图7所示的实施例与图8所示的实施例的区别在于，图8所示的实施例中，由于主芯片成功接收数据包，因此主芯片可以直接通知终端设备数据包接收成功。而图7所示的实施例中， 由于主芯片接收数据包失败，而从芯片接收数据包成功，因此主芯片是在获知从芯片接收数据包成功以后，再通知终端设备数据包接收成功。
可选的，该方法还可以包括步骤S710。
S710、第一短距无线通信芯片向第二短距无线通信芯片发送第四信息。
该第四信息用于指示第一短距无线通信芯片成功接收数据包。
可选的，无论第一短距无线通信芯片和第二短距无线通信芯片是否成功接收终端的数据包，第一短距无线通信芯片和第二短距无线通信芯片都可以通过数据总线告知对方自己是否成功接收到来自终端设备的数据包，以实现双耳间的同步。
需要说明的是，本申请对于图8所示的步骤S707-S710的执行顺序并不进行限定，图8仅是示例性说明。例如，步骤S709可以在步骤S707之前执行，也可以在步骤S707之后执行，还可以和步骤S707同时执行。
本申请实施例还提供一种头戴式无线耳机的通信方法，如图9所示，若第一短距无线通信芯片为主芯片，第二短距无线通信芯片为从芯片，主芯片和从芯片均未成功接收数据包，在上述步骤S701-S702之后还可以包括以下步骤：
S711、在第二短距无线通信芯片未成功接收数据包的情况下，第二短距无线通信芯片通过数据总线向第一短距无线通信芯片发送第五信息。
该第五信息用于指示第二短距无线通信芯片未成功接收数据包。
S712、在第一短距无线通信芯片未成功接收数据包的情况下，第一短距无线通信芯片响应第五信息，向终端设备发送第六信息。
该第六信息用于指示终端设备重传数据包。
可以理解的，在本实施例中，由于主芯片和从芯片均未成功接收数据包，因此主芯片通过数据总线获知从芯片也未成功接收数据包后，可以通过空口通知终端设备重传数据包。也就是说，本申请实施例只有在两个短距无线通信芯片均接收数据包失败的情况下，终端设备才会重传数据包。因此，能够提高头戴式无线耳机接收数据包的成功率。
可选的，上述图7-图9任一实施例所示的头戴式无线耳机的通信方法，还可以包括步骤S713。图10仅以图7所示的实施例还包括步骤S713为例进行示意。
S713、基于第一短距无线通信芯片和第二短距无线通信芯片接收信号的信号质量参数，在第一短距无线通信芯片和第二短距无线通信芯片中确定主芯片。
可选的，上述接收信号的信号质量参数包括：参考信号接收功率RSRP、参考信号接收质量RSRQ、接收信号强度指示RSSI、丢包率PER，以及信号与干扰加噪声比SINR中的任意一种或多种。
可选的，上述步骤S713的执行主体可以为主芯片，该主芯片可以为第一短距无线通信芯片，也可以为第二短距无线通信芯片。
示例性的，在头戴式无线耳机出厂时可以将第一短距无线通信芯片和第二短距无线通信芯片中的任意一个短距无线通信芯片设置为主芯片，在头戴式无线耳机使用过程中，可以由该主芯片根据第一短距无线通信芯片和第二短距无线通信芯片接收信号的信号质量参数，动态的将接收信号的信号质量参数较好的短距无线通信芯片确定为主芯片。也就是说，在头戴式无线耳机使用过程中，随着终端设备位置等参数的变化， 主芯片可能会在第一短距无线通信芯片和第二短距无线通信芯片之间切换。
例如，以头戴式无线耳机出厂时将左耳机中的第一短距无线通信芯片设置为主芯片为例，在头戴式无线耳机使用过程中，如果右耳机中的第二短距无线通信芯片接收信号的信号质量参数较左耳机中的第一短距无线通信芯片接收信号的信号质量参数好，那么第一短距无线通信芯片可以将第二短距无线通信芯片确定为主芯片，并告知第二短距无线通信芯片其为主芯片，由第二短距无线通信芯片继续执行主芯片的功能。可选的，第一短距无线通信芯片将第二短距无线通信芯片确定为主芯片，第一短距无线通信芯片可以将主芯片的权限转移给第二短距无线通信芯片，即第二短距无线通信芯片为主芯片，后续可以由第二主芯片告知终端设备数据包是否接收成功。
可选的，在头戴式无线耳机使用过程中，可以每隔一段时间执行一次步骤S713确定一次主芯片，也可以实时地执行步骤S713确定主芯片，还可以在当前主芯片的信号质量参数较差的情况下再执行步骤S713确定主芯片，本申请实施例对此并不限定。
本申请实施例对于步骤S713与步骤S701-S702的先后执行顺序并不限定，图10仅以步骤S713在步骤S701-S702之前执行为例进行示意。实际应用中，步骤S713也可以在步骤S701-S702之前执行，或者步骤S713还可以与步骤S701-S702同时执行。
本实施例提供的头戴式无线耳机的通信方法，两个短距无线通信芯片之间通过数据总线交互，能够释放一部分空口资源，降低数据包的重传次数，降低终端设备及耳机的功耗。
图11为本申请实施例提供的一种头戴式无线耳机的通信效果示意图，图11中的(a)为图3所示的头戴式无线耳机的通信效果示意图，图11中的(b)为图4所示的头戴式无线耳机的通信效果示意图。如图11中的(a)所示，手机发送数据包1后，主耳和副耳尝试接收该数据包1(图11中的斜线填充的矩形框表示尝试去做接收)，如果主耳(主芯片所在的耳机)和副耳(从芯片所在的耳机)均接收数据包1失败，那么主耳向手机发送NACK。手机重传数据包1，如果主耳接收数据包1失败，副耳接收数据包1成功，那么副耳向主耳发送同步包，告知主耳副耳成功接收数据包1。由于主耳的丢包会对副耳造成影响，导致主耳和副耳都不能播放音频数据，因此主耳向手机发送否定应答NACK。手机再次重传数据包1，如果主耳接收数据包1成功，副耳接收数据包1失败，副耳的丢包会对主耳造成影响，导致主耳和副耳都不能播放音频数据，因此主耳向手机发送否定应答NACK。手机再次重传数据包1，如果主耳和副耳均成功接收数据包1，那么副耳向主耳发送同步包，告知主耳副耳成功接收数据包1，由于主耳也成功接收数据包1，故主耳向手机发送ACK，告知手机数据包1接收成功。
可以理解的，采用图3所示的头戴式无线耳机通信时，双耳之间的丢包会互相影响，只要有一个耳机接收数据包失败，那么该耳机的丢包会影响另一个耳机，造成两个耳机都不能播放音频数据。只有在两个耳机都成功接收数据包的情况下，才能正常播放音频数据，因此，头戴式无线耳机接收数据包的成功率较低。
如图11中的(b)所示，手机发送数据包1后，如果主耳和副耳均接收数据包1失败，主耳和副耳之间会通过数据总线进行双耳同步以确定对方是否成功接收到数据包1，当主耳确定主耳和副耳均接收数据包1失败时，主耳向手机发送否定应答NACK。 手机重传数据包1，如果主耳接收数据包1失败，副耳接收数据包1成功，主耳会通过数据总线告知副耳其接收数据包1失败(双耳同步)，以请求副耳转发数据包1，当副耳获知主耳接收数据包1失败时，副耳通过数据总线向主耳发送其成功接收的数据包1(图11中的(b)所示的数据补发)。副耳成功接收数据包1后通知主耳(双耳同步)，当主耳确定副耳成功接收数据包1时，主耳可以向手机发送ACK，告知手机数据包1接收成功。手机发送数据包2，如果主耳成功接收该数据包2，副耳接收数据包失败2，副耳之间会通过数据总线告知主耳其接收数据包2失败(双耳同步)，以请求主耳转发数据包2，当主耳获知副耳接收数据包2失败时，主耳将其成功接收的数据包2通过双耳间的数据总线发送给副耳。主耳向手机发送ACK，告知手机数据包2接收成功。手机发送数据包3，如果主耳和副耳均成功接收该数据包3，主耳和副耳之间可以通过数据总线进行双耳同步，主耳向手机发送ACK，告知手机数据包3接收成功。
如图11中的(b)所示，在主耳和副耳中的至少一个耳机成功接收手机发送的数据包的情况下，主耳就可以向手机发送ACK，告知手机数据包接收成功，如果主耳和副耳中只有一个耳机成功接收该数据包，那么成功接收数据包的耳机可以通过数据总线向接收数据包失败的耳机转发其成功接收的数据包。
可以理解的，采用图4所示的头戴式无线耳机通信时，双耳之间的丢包不会互相影响，只要有一个耳机成功接收数据包，成功接收数据包的短距无线通信芯片可以通过数据总线向未成功接收数据包的短距无线通信芯片补发数据包，终端设备无需重传数据包。只有在两个短距无线通信芯片均接收数据包失败的情况下，终端设备才会重传数据包。因此，图4所示的头戴式无线耳机接收数据包的成功率较高。
如图11中的(a)所示，手机和双耳交互完音频数据后，如果双耳间没有数据交互，双耳间还需要通过Polling轮询机制，由主耳定期发送POLL包，副耳回复NULL包，告知主耳，副耳当前没有数据传输，以维持双耳间的链路正常。当双耳之间需要交互数据(例如，双耳间交互耳机音量、时间戳、日志等信息)时，可以将POLL包和NULL包替换为数据包，以完成双耳间的数据交互。如图11中的(b)所示，手机和双耳交互完音频数据后，由于双耳之间是通过数据总线交互的，可以通过数据总线传输耳机音量、时间戳、日志等信息，无需维持双耳间的空口链路，因此能够节省空口资源，提升蓝牙耳机接收数据包的成功率。而且双耳间通过数据总线重传数据包的传输速度较快，能够降低终端设备和头戴式无线耳机的功耗。
可以理解的，图4所示的头戴式无线耳机较图3所示的头戴式无线耳机，由于在双耳的短距无线通信芯片间设置了数据总线，双耳之间可以通过该数据总线补发数据包，因此只有在两个耳机都没有成功接收数据包的情况下，才需要手机重传数据包，能够提升头戴式无线耳机接收数据包的成功率。而且双耳之间通过数据总线同步，而不是通过空口交互，因此能够释放一部分空口资源，降低数据包的重传次数，降低终端设备及耳机的功耗。
需要说明的是，本申请实施例中的主耳可以为头戴式无线耳机的左耳机，也可以为头戴式无线耳机的右耳机，本申请实施例对此并不限定。
本申请实施例还提供一种计算机可读存储介质，该计算机可读存储介质中存储有 计算机程序代码，当计算机程序代码在短距无线通信芯片上运行时，使得短距无线通信芯片执行图7至图10中任一实施例所示的头戴式无线耳机的通信方法。
本申请实施例还提供一种计算机程序产品，当该计算机程序产品在头戴式无线耳机上运行时，使得头戴式无线耳机执行图7至图10中任一实施例所示的头戴式无线耳机的通信方法。
结合本申请公开内容所描述的方法或者算法的步骤可以硬件的方式来实现，也可以是由处理器执行软件指令的方式来实现。软件指令可以由相应的软件模块组成，软件模块可以被存放于随机存取存储器(random access memory，RAM)、闪存、可擦除可编程只读存储器(erasable programmable ROM，EPROM)、电可擦可编程只读存储器(electrically EPROM，EEPROM)、寄存器、硬盘、移动硬盘、只读光盘(CD-ROM)或者本领域熟知的任何其它形式的存储介质中。一种示例性的存储介质耦合至处理器，从而使处理器能够从该存储介质读取信息，且可向该存储介质写入信息。当然，存储介质也可以是处理器的组成部分。处理器和存储介质可以位于ASIC中。另外，该ASIC可以位于核心网接口设备中。当然，处理器和存储介质也可以作为分立组件存在于核心网接口设备中。
