Description

蓝牙耳机的数据接收方法、装置、设备及存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种蓝牙耳机的数据接收方法、装置、设备及存储介质。
背景技术
TWS(True Wireless Stereo，真无线立体声)耳机包括两只独立的耳机，分别用于用户左右耳。两只耳机之间无需线缆连接，可以实现左右声道的无线分离。
目前，TWS耳机在使用时，会定义其中一个耳机为主耳机，通常用于与音源设备直接建立连接，以通过该连接与音源设备通信，接收音源设备发送的音频数据，并反馈音频数据是否正确接收。从耳机为另外一个耳机，通常与音源设备之间没有直接的连接，需要通过主耳机反馈其是否正确接收音频数据。
然而，由于主耳机需要收到从耳机发送的肯定应答，才向音源设备发送肯定应答，这种方式容易导致音频数据卡顿或停止播放等影响用户收听体验。
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本公开将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。
此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在 不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
此外，在本公开的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
图1示出了相关技术中TWS蓝牙耳机主从耳机之间数据接收方法的示意图。
如图1所示，当从耳机通过监听主耳机与音源设备之间的无线连接，正确接收到音源设备发送的音频数据时，从耳机向主耳机发送ACK(肯定应答)。主耳机在收到从耳机发送的ACK，并且主耳机也正确接收到该音频数据时，主耳机向音源设备发送ACK，以通知音源设备可以发送下一包音频数据。
但是，如果主耳机与从耳机之间存在干扰(例如头部遮挡干扰)，则主耳机可能一直无法收到从耳机发送的ACK，主耳机就会不断的向音源设备发送重传请求，该操作一直循环发生，最终会导致主从耳机由于没有足够的音源数据播放而发生卡顿或者停止播放。
有鉴于此，本公开实施例提供一种蓝牙耳机的数据接收方法、装置、设备及存储介质。
图2是根据一示例性实施例示出的音频播放系统的示意图。如图2所示，音频播放系统1包括：音源设备11、TWS蓝牙耳机中的主耳机12及从耳机13。
音源设备11可以为具有蓝牙通信功能的智能设备，如智能手机、平板电脑等。
音源设备11与主耳机12之间通过建立的第一无线链路L1进行通信。
主耳机12与从耳机13之间通过建立的第二无线链路L2进行通信。
第一无线链路L1与第二无线链路L2均为基于蓝牙通信协议建立的无线连接。
下面将结合附图及实施例对本公开实施方式中的各蓝牙耳机的数据接收方法的各个步骤进行更详细的说明。
图3示出本公开实施例中一种蓝牙耳机的数据接收方法的流程图。本公开实施例提供的方法可以由TWS蓝牙耳机中的主耳机执行。
参考图3，蓝牙耳机的数据接收方法10包括：
在步骤S102中，蓝牙耳机的主耳机将主耳机与音源设备之间的第一无线链路的连接参数信息，发送给蓝牙耳机的从耳机。
结合图2，主耳机12与音源设备11之间建立第一无线链路L1。为了使从耳机13可以通过监听第一无线链路L1来接收音源设备11发送的音频数据，主耳机12需要将第一无线链路L1的连接参数信息发送给从耳机13。连接参数信息例如可以包括：第一无线链路的连接信息(如音源设备11的蓝牙通信地址等)、跳频信息(如跳频序列、AFH频道地图表等)及加密信息(如密钥等)等信息。基于这些信息，从耳机13可以主动对第一无线链路进行监听，从而获取该第一无线链路上传输的数据。
例如，主耳机12可以通过与从耳机13之间的第二无线链路L2，将第一无线链路L1的连接参数信息发送给从耳机13。
在步骤S104中，主耳机通过第一无线链路接收音源设备发送的第一音频数据。
主耳机12通过第一无线链路接收音源设备发送的第一音频数据。
从耳机13通过监听第一无线链路来获取音源设备在第一无线链路上发送的第一音频数据。
在步骤S106中，主耳机检测是否在预设时间内接收到从耳机发送的反馈。
主耳机12还会检测是否接收到从耳机13发送的任何反馈，该任何反馈例如可包 括否定反馈信息，该否定反馈信息用于指示从耳机没有正确接收到第一音频数据。
例如，主耳机12还会利用与音源设备11通信的间隙，通过监听第二无线链路L2，检测是否接收到从耳机13发送的否定反馈信息。
在本公开实施例中，从耳机13仅在没有正确接收第一音频数据时，才向主耳机12发送否定反馈信息，以指示其没有正确接收第一音频数据。而不会在每次正确接收到一包音频数据后，向主耳机12发送肯定反馈信息(如上述的ACK)。也即，每次正确接收到音频数据后，从耳机13不向主耳机12发送任何反馈。
在蓝牙通信中，通信双方会设定各自的发射时隙与接收时隙，一方的发射时隙为另一方的接收时隙，从而确保双方可以正确通信。在一些实施例中，主耳机12在第二无线链路L2中的接收时隙检测在第二无线链路L2上是否有从耳机发送的数据，以检测是否接收到从耳机发送的反馈。
在步骤S108中，当主耳机正确接收到第一音频数据，并且在预设时间内没有接收到从耳机发送的任何反馈时，向音源设备发送肯定应答消息，以通知音源设备发送第二音频数据。
其中，主耳机12在自身正确接收了第一音频数据后，并且在预设时间内没有接收到从耳机发送的任何反馈时，才会向音源设备11发送ACK，以通知音源设备发送第二音频数据(下一包音频数据)。
进一步的，在预设时间内没有接收到所述从耳机发送的任何反馈包括：
在预设时间内没有接收到所述从耳机发送的上述否定反馈信息。
也就是说，在预设时间内没有接收到所述从耳机发送的否定反馈信息，可能是因为从耳机正确接收音频信号从而没有发送反馈，或者主从耳机之间的第二无线链路通信质量差导致无法接收到否定反馈信息的情况。该预设时间例如设置小于或等于上述主耳机12在第二无线链路L2中的接收时隙的时长。也即如果在该接收时隙之内，没有接收到从耳机13发送的反馈信息，即认为从耳机13已经正确地接收了第一音频数据。
在一些实施例中，蓝牙耳机的数据接收方法10还可以包括：
在步骤S110中，当主耳机没有正确接收到第一音频数据时，或者，当主耳机在预设时间内接收到了从耳机发送的否定反馈信息时，向音源设备发送否定应答消息，以通知音源设备重新发送第一音频数据。
如果主耳机12自身没有正确接收到第一音频数据，或者主耳机12在预设时间内接收到了从耳机13发送的否定反馈信息，则主耳机12向音源设备11发送否定应答消息，从而通知音源设备11重新发送第一音频数据。
也即，当所述主耳机没有正确接收到所述第一音频数据时，或者，当所述主耳机在所述预设时间内接收到从耳机发送的否定反馈信息时，向所述音源设备发送否定应答消息，以通知所述音源设备重新发送所述第一音频数据。
根据本公开实施例提供的蓝牙耳机的数据接收方法，主耳机尝试接收从耳机发送的否定反馈信息，并在上述的预设时间内没有接收到该否定反馈信息时，认为从耳机正确接收了音源设备发送的音频数据。通过该方法，在主从耳机之间的无线通信环境较差时(如存在较为严重的干扰时)，如果主耳机在预设时间内因为存在干扰而没有接收到从耳机发送的反馈信息，主耳机也会认为从耳机正确接收了音频数据，因此主耳机会继续请求音源设备发送下一包音频数据，保证了至少有一个耳机可以正常接收音频数据，从而避免了相关技术中由于音源设备不停的重传一包音频数据而导致的播放卡顿或停止的问题。
此外，从耳机仅在没有正确接收到音源设备发送的音频数据时，才会向主耳机发送否定反馈信息，通过该方法，在主从耳机之间的无线通信环境较佳时(如信号强度 比较强、干扰比较小时)，还可以减小主从耳机之间的数据发送，减小从耳机的功率损耗。
此外，在一种可行的实施方式中，从耳机监听第一无线链路中的第一音频数据后，如果正确获取第一音频数据则向主耳机发送肯定反馈信息ACK，如果未正确获取第一音频数据则向主耳机发送否定反馈信息NACK。主耳机在自身正确接收到第一音频数据且收到从耳机发送的ACK时，向音源设备发送肯定应答，以使得音源设备发送第二音频数据；主耳机在自身未正确接收到第一音频数据，或者收到从耳机发送的NACK时，向音源设备发送否定应答，以使得音源设备重发第一音频数据；主耳机在自身正确接收到第一音频数据且在预设时间内未收到从耳机的任何反馈(包括未收到ACK，也未收到NACK)时，则向音源设备发送肯定应答，以使得音源设备发送第二音频数据；从而可以保障，因为头部遮挡等导致第二无线链路通信质量差时，仍能够保障主耳机的接收和播放。
在另一种可行的实施方式中，从耳机监听第一无线链路中的第一音频数据后，如果正确获取第一音频数据则向主耳机发送肯定反馈信息ACK，如果未正确获取第一音频数据则不向主耳机发送任何反馈信息。主耳机在自身正确接收到第一音频数据且收到从耳机发送的ACK时，向音源设备发送肯定应答，以使得音源设备发送第二音频数据；当主耳机自身正确接收到第一音频数据，且在预设时间内未收到从耳机发送的任何反馈信息(包括从耳机有发送ACK，但因第二无线链路通信质量差未收到的情况和从耳机没有发送任何反馈信息的情况)时，则向音源设备发送肯定应答，该实施方式，也可以保障主耳机的接收和播放。
图4示出本公开实施例中另一种蓝牙耳机的数据接收方法的流程图。本公开实施例提供的方法可以由TWS蓝牙耳机中的从耳机执行。
联合参考图2和图4，蓝牙耳机的数据接收方法20包括：
在步骤S202中，蓝牙耳机的从耳机接收蓝牙耳机的主耳机发送的、主耳机与音源设备之间的第一无线链路的连接参数信息。
如上述，从耳机13接收主耳机12发送的第一无线链路L1的连接参数信息，连接参数信息例如可以包括：第一无线链路的连接信息(如音源设备11的蓝牙通信地址等)、跳频信息(如跳频序列、AFH频道地图表等)及加密信息(如密钥等)等信息。
从耳机13例如通过上述的第二无线链路L2接收该连接参数信息。
在步骤S204中，基于连接参数信息，从耳机监听第一无线链路，以获取音源设备发送的第一音频数据。
基于如上述的连接参数信息，从耳机13可以监听第一无线链路L1，检测其中是否有音源设备11发送的第一音频数据。
在步骤S206中，当从耳机没有正确获取到第一音频数据时，向主耳机发送否定反馈信息。
该否定反馈信息用于指示从耳机没有正确获取到第一音频数据。
从耳机13在接收到第一音频数据后，确定是否正确获取了该第一音频数据，例如通过校验的方式确定获取到的第一音频数据是否正确。
如果正确获取了第一音频数据，从耳机13不向主耳机12发送肯定确认(也即不发送任何反馈)。而是仅在没有正确获取时，从耳机13才向主耳机12发送否定反馈信息，以指示其没有正确接收该第一音频数据。
从耳机13例如可以通过上述的第二无线链路L2发送反馈。
根据本公开实施例提供的蓝牙耳机的数据接收方法，从耳机仅在没有正确获取到 音源设备发送的音频数据时，才会向主耳机发送否定反馈信息。通过该方法，在主从耳机之间的无线通信环境较差时(如存在较为严重的干扰时)，如果主耳机在预设时间内因为存在干扰而没有接收到从耳机发送的反馈信息，主耳机也会认为从耳机正确接收了音频数据，因此主耳机会继续请求音源设备发送下一包音频数据，保证了至少有一个耳机可以正常接收音频数据，从而避免了相关技术中由于音源设备不停的重传一包音频数据而导致的播放卡顿或停止的问题。
此外，通过该方法，在主从耳机之间的无线通信环境较佳时(如信号强度比较强、干扰比较小时)，还可以减小主从耳机之间的数据发送，减小从耳机的功率损耗。
图5示出本公开实施例中再一种蓝牙耳机的数据接收方法的流程图。
联合参考图2和图5，蓝牙耳机的数据接收方法50包括：
在步骤S502中，蓝牙耳机的主耳机将主耳机与音源设备之间的第一无线链路的连接参数信息，发送给蓝牙耳机的从耳机。
在步骤S504中，主耳机通过第一无线链路接收音源设备发送的第一音频数据。
在步骤S506中，从耳机基于连接参数信息，监听第一无线链路，以获取第一音频数据。
在步骤S508中，当主耳机正确接收到第一音频数据，并且在预设时间内没有接收到从耳机发送的任何反馈时，向音源设备发送肯定应答消息，以通知音源设备发送第二音频数据。
在一些实施例中，任何反馈例如可以包括：用于表示所述从耳机没有正确接收到所述第一音频数据的否定反馈信息。方法50在步骤S508之前，如还可以包括：当从耳机没有正确获取到第一音频数据时，向主耳机发送否定反馈信息；及当从耳机正确获取到所述第一音频数据时，不向主耳机发送表示从耳机正确接收到第一音频数据的肯定反馈信息。
在一些实施例中，方法50还可以包括：在步骤S510中，当主耳机没有正确接收到第一音频数据时，或者，当主耳机在所述预设时间内接收到所述从耳机发送的否定反馈信息时，向音源设备发送否定应答消息，以通知音源设备重新发送第一音频数据。
根据本公开实施例提供的蓝牙耳机的数据接收方法。主耳机在上述的预设时间内没有接收到从耳机的任何反馈(包括否定反馈信息)时，认为从耳机正确接收了音源设备发送的音频数据。通过该方法，在主从耳机之间的无线通信环境较差时(如存在较为严重的干扰时)，如果主耳机在预设时间内因为存在干扰而没有接收到从耳机发送的反馈信息，主耳机也会认为从耳机正确接收了音频数据，因此主耳机会继续请求音源设备发送下一包音频数据，保证了至少有一个耳机可以正常接收音频数据，从而避免了相关技术中由于音源设备不停的重传一包音频数据而导致的播放卡顿或停止的问题。
此外，进一步的，从耳机仅在没有正确接收到音源设备发送的音频数据时，才会向主耳机发送否定反馈信息，通过该方法，在主从耳机之间的无线通信环境较佳时(如信号强度比较强、干扰比较小时)，还可以减小主从耳机之间的数据发送，减小从耳机的功率损耗。
图6示出本公开实施例中再一种蓝牙耳机的数据接收方法的流程图。
联合参考图2和图6，蓝牙耳机的数据接收方法30包括：
在步骤S311中，音源设备11与主耳机12建立第一无线链路L1。

在步骤S313中，主耳机12将第一无线链路L1的连接参数信息发送给从耳机13。
在步骤S314中，音源设备11向主耳机12发送第一音频数据。
在步骤S315中，从耳机13通过监听该第一无线链路L1，来检测是否接收到第一音频数据。
在步骤S316中，主耳机12判断自身是否正确接收到了第一音频数据。如果正确接收，则进入步骤S317；否则，进入步骤S320。
在步骤S317中，主耳机12向音源设备11发送否定应答消息NACK，以通知音源设备11重发第一音频数据。
在步骤S318中，从耳机13判断自身是否正确接收到了第一音频数据。如果正确接收，进入步骤S326；否则，进入步骤S319。
在步骤S319中，从耳机13向主耳机12发送否定反馈信息，指示其没有正确接收第一音频数据。
在步骤S320中，主耳机12判断是否接收到从耳机13发送的否定反馈信息。如果接收了，进入步骤S321；否则，进入步骤S322。
在步骤S321中，主耳机12向音源设备11发送否定应答消息NACK，以通知音源设备11重发第一音频数据。
在步骤S322中，主耳机12判断是否到达预设时间。如果到达，则进入步骤S323；否则，返回步骤S320。
在步骤S323中，主耳机12向音源设备11发送肯定应答消息，以通知音源设备11发送第二音频数据。
在步骤S324中，音源设备11判断是否接收到肯定应答消息。如果接收到，则进入步骤S325；否则，返回步骤S314，重新发送第一音频数据。
在步骤S325中，音源设备11基于第一无线链路L1发送第二音频数据。
在步骤S326中，从耳机13通过监听该第一无线链路L1，来检测是否接收到第二音频数据。
