Abstract

本申请实施例公开了一种无线短距离音频共享方法，不需要音源方和音频接收方之间在传输音频数据之前先建立无线短距离的通信连接，而是由音源方向音频接收方广播音频，以实现音频共享。例如，音源方先根据用户的操作开启BLE音频广播，然后根据用户的操作或者自动确定第一音频文件，将该第一音频文件转换成至少一个音频数据包进行BLE音频广播和对应的周期广播。音源接收方在用户触发后，扫描周期广播，并接入接收到的一个周期广播对应的BLE音频广播，然后将该BLE音频广播的至少一个音频数据包转换为音频进行播放。

Description

无线短距离音频共享方法及电子设备 技术领域
本申请涉及通信技术领域，尤其涉及一种无线短距离音频共享方法及电子设备。
背景技术
近年来，随着无线音频技术的发展，越来越多的扬声器和耳机类音频设备采用蓝牙、无线保真(wireless fidelity，Wi-Fi)等无线技术进行音频传输。受限于蓝牙音频传输模型协定(advanced audio distribution profile，A2DP)的限制，蓝牙音频设备只能支持一个音源设备到一个音频接收方设备的音频传输。
为支持一个音源设备到多个音频接收方设备进行音频传输，可以利用Wi-Fi技术或者蓝牙低功耗(bluetooth low energy，BLE)技术实现。基于Wi-Fi的私有协议来实现的音频共享，往往不能兼容所有的音频设备。另外，基于Wi-Fi技术的音频共享方案和基于BLE技术的音频共享方案，往往需要先根据用户的操作建立音源设备和多个音频接收方设备之间的无线连接，然后根据用户的操作选择一个或多个音频文件进行共享。上述的音频共享过程操作繁琐，降低了音频共享的便利性。
由此可见，如何方便的实现音频共享，是亟待解决的问题。
发明内容
本申请实施例提供了一种无线短距离音频共享方法及电子设备，可以简化音频信号共享的操作流程，提高音频共享的便利性。
第一方面，本申请实施例提供了一种无线短距离音频共享方法，由第一音频设备执行，该方法可包括：检测用户的第一操作；响应于该第一操作，开启BLE广播功能；检测用户的第二操作；响应于该第二操作，选择第一音频文件；将该第一音频文件转换至少一个音频数据包，将该至少一个音频数据包进行BLE广播，并进行与该BLE广播对应的周期广播。
述的无线短距离音频共享方法中，先打开BLE广播功能，再选择媒体，即可进行音频共享。因此，第一音频设备无需与其他设备建立通信连接，其他设备可以接收该BLE广播并提取BLE广播上的音频数据来进行音频播放，音频数据由第一音频设备单向传输给其他设备，从而省略了建立蓝牙连接过程中用户的操作，可以简化来自第一音频设备的音频信号共享的操作流程，提高音频共享的便利性。在一种可能的实现方式中，在将第一音频文件对应的音频数据包进行广播的过程中，例如正在广播音乐文件时，如果第一音频设备需要播放第二音频文件(如接收到新短信需要播放短信提示音文件，或者在允许响铃提示的模式时接收到来电需要播放铃声提示音文件)，第一音频设备将第一音频文件和第二音频文件混音、解码并转换为至少一个音频数据包，将上述至少一个音频数据包进行BLE广播，并进行与该BLE广播对应的周期广播。
在一种可能的实现方式中，如果第一音频设备完成对第一音频文件进行BLE广播，可以获取音频文件列表中第一音频文件的下一个音频文件，并继续对该下一个音频文件进行 BLE音频广播。例如，在音乐APP中，在完成第一音频文件进行BLE音频广播后，继续对音乐列表中第一音频文件的下一首音频文件进行BLE广播。本实现方式，在音频文件共享完成后，自动选取下一首进行音频共享，减少了用户手动操作，提高音频共享的便利性。
另外，如果第一音频设备完成对第一音频文件进行BLE广播，也可以停止发送BLE广播。
在一种可能的实现方式中，该第一音频设备为手机；检测用户的第一操作之前，该方法还包括，显示设置应用的界面，该设置应用的界面包括BLE广播开关(即BLE音频广播开关)；该第一操作为开启该BLE广播开关的操作；开启音频广播功能之后，该方法还包括，接收用户的第三操作，显示媒体文件播放应用的界面，该媒体文件播放应用的界面包括播放控件和该第一音频文件的标识；该第二操作为选择该播放控件的操作。
其中，显示设置应用的界面之前，该方法还包括，显示主屏幕界面；主屏幕界面上包含应用程序图标，应用程序图标包含设置图标。检测到用户对设置图标的点击操作时，显示设置应用的界面。
另外，设置应用的界面也可以是响应于用户对下拉菜单中的BLE广播图标(即BLE音频广播图标)的长按或其他操作显示的。

以下先简要介绍一些实施例中的概念。
(1)播放器
播放器可以包含音乐APP、视频APP等。在播放器的用户界面上，第一音频设备可以响应用户操作来对音频文件进行播放、缓存、删除等操作。例如，在音乐APP界面中，检测到歌名“Dream it possible”的触摸操作，第一音频设备100将歌名“Dream it possible”对应的音频文件转换为PCM文件。然后，第一音频设备100根据该PCM文件进行音频播放或者转换为BLE音频广播并广播。
播放器还可以包含短信APP、微信APP、淘宝APP、Facebook APP等。在需要音频提醒(例如消息提醒)时，播放器可以自动调用***提示音文件。例如，在微信APP接收到新消息时，微信APP请求调用***消息提示音文件。第一音频设备100将该***消息提示音文件转换为PCM文件，根据该PCM文件进行音频播放或者转换为BLE音频广播并广播。
播放器还可以包含拨号APP等。在拨号APP接收到来电且第一音频设备处于允许响铃提示的模式时，拨号APP请求调用***铃声提示音文件。第一音频设备100将该***铃声提示音文件转换为PCM文件，根据该PCM文件进行音频播放或者转换为BLE音频广播并广播。
(2)PCM文件
PCM文件由音频文件处理得到。其中，音频文件的格式可以是mp3、wav。PCM文件是由1、0等符号构成的数字文件，未经过任何编码和压缩处理。在一些实施例中，PCM文件只有编码的音频数据，没有其他描述信息。音频文件处理可以包含对音频文件进行解 码，在音频文件解码的过程中，可以提取音频文件的音频数据，并读取音频文件的描述信息。音频文件的音频数据是以数字信号形式存储的音频数据。该音频数据可以按播放的先后顺序依次存放，或者按其他方式存放但备注有播放的先后顺序的信息。音频文件的描述信息可以包括：音频文件的采样率、时长、声道数、音频文件类型。音频文件解码得到PCM文件的过程还可以根据音频输出设备的需求调整音频文件的采样率、时长、声道数等。
对音频文件处理还可以包含混音。例如，在多个音频文件需要同时转换为PCM文件时，可以将这多个音频文件进行混音。例如，在使用音乐APP播放音乐时，微信APP接收到新消息。在进行音频处理时，可以将音乐文件和***消息提示音文件混音并进行转换，得到PCM文件。然后电声转换器可以根据PCM文件进行音频播放。
(3)BIS数据
BLE的广播通信功能可以使用基于蓝牙广播的同步通道(isochronous channels)传输协议实现。同步通道的传输模式中，基于广播的等时流(broadcast isochronous stream，BIS)可以实现一个数据源广播的数据被多个数据接收方接收。PCM文件可以通过BIS数据广播。
BIS是数据源(broadcaster)在广播范围内发送的等时数据流。数据接收方在广播范围内进行接收等时流。在BIS数据传输过程中，数据源和数据接收方之间不需先建立现有的蓝牙连接或Wi-Fi连接，等时流由数据源单向传输给数据接收方。
其中，数据源是广播等时流的设备。数据接收方可以是在广播范围内任何接收等时流的设备。本申请实施例中，数据源即为音频源，数据接收方即为音频接收方。
BIS的时域资源由每个等时间隔发生的广播等时流事件(BIS event)组成。数据源在广播等时流事件中发送数据。每个广播等时流事件被划分为一个或多个子事件(subevent)。即一个等时流事件具有一个或多个用于传输广播同步数据包(broadcast isochronous data packets)的子事件。由于数据源和数据接收方之间不需先建立现有的蓝牙连接或Wi-Fi连接，为了提高等时流传输的可靠性，每个等时流事件中的子事件可以重复传输BIS数据包。PCM文件可以被分段并打包成数据包在等时流事件的子事件中传输。
一个数据源可以建立多个BIS组成的基于广播的等时组(broadcast isochronous group，BIG)，并在这多个BIS上传输数据。数据接收方可以接收BIG中所有BIS上广播的数据，也可以仅接收BIG中部分BIS上广播的数据。BIG可以包含一个或多于一个BIS。
(4)周期广播
数据源在传输广播同步数据包的同时，可以周期性的广播周期广播(periodic advertisement)。周期广播的ACAD字段可以携带BIG信息(broadcast isochronous group synchronization information，BIGInfo)。数据接收方可以接收周期广播并获取BIGInfo。数据接收方可以根据BIGInfo同步到BIG，从而获取BIG上的音频广播数据，即BIS数据包。
BIGInfo例如可以包含帧间隔(frame interval)、帧大小(frame size)、传输延迟(transport latency)、重传次数(retransmission effort，RTE)、调度方式(packing)。
其中：
帧间隔：用于描述周期性的数据帧的时间间隔。在一个BIG中，所有BIS之间的数据帧的帧间隔取值相同。在数据链路层上，音频数据以数据帧(data frame)为数据单元传输。
帧大小：用于描述数据帧的最大长度。
传输延迟：用于描述BIS数据在数据源和数据接收方的相同数据层级之间传输所需要的最长时间间隔。
重传次数：用于描述每个数据协议数据单元(protocol data unit，PDU)被重复传输的次数。
调度方式：用于描述多个BIS的子事件的调度方法。该调度方法可以是串行(sequential)、交织(interleaved)或者不限制。只有当BIG中包含两个或两个以上的BIS时，该参数才有效。
为提高音频共享的便利性，本申请实施例提供一种音频共享方法。下面以蓝牙广播为例描述本申请实施例涉及的实现过程。如图1所示，其中，第一音频设备100是音频源，是手机。手机包含BLE音频广播功能。第二音频设备200和第三音频设备300是音频接收方，第二音频设备200是蓝牙耳机1，第三音频设备300是蓝牙耳机2。蓝牙耳机1和蓝牙耳机2均包含接收周期广播和BLE音频广播的模块。

当第一音频设备100正在将上述PCM文件打包并进行BLE音频广播时，第一音频设备100可以在通知栏或者负一屏上显示“正在进行BLE音频广播yesterday once more”或“正在共享yesterday once more”的提示，参考图6E附图描述。上述提示还可以在第一音频设备100的上拉菜单202、侧拉菜单203、悬浮菜单204、桌面或锁屏界面显示。
在一些实施例中，第一音频设备100将音频文件处理得到BLE音频广播的过程如下：第一音频设备100从音频文件中提取音频数据。音频数据可以打包成PCM文件。PCM文件是以数字信号形式存储的音频数据。然后音频源读取音频文件的描述信息。音频文件的描述信息包含采样率、时长、声道数。接下来，第一音频设备100将该PCM文件分段并承载在BLE音频广播上发送。
第二音频设备200从S115开始可以接收BLE音频广播，使用电声转换器进行播放。具体的，第二音频设备200和第三音频设备300可以提取BLE音频广播的BIS数据包。第二音频设备200和第三音频设备300将BIS数据包进行数模转换得到模拟信号形式的音频数据，第二音频设备200和第三音频设备300将该模拟信号形式的音频数据转换为音频播放。
可选的，在第一音频设备100进行BLE音频广播的同时，第一音频设备100可以同步 使用自身的扬声器或者使用与第一音频设备100建立连接的耳机播放歌名“yesterday once more”对应的音频文件。PCM文件可以被打包为BLE音频广播。PCM文件也可以被进行数模转换，然后被第一音频设备100自身的扬声器170A播放。
S110、第一音频设备100根据上述PCM文件使用自身的扬声器或者使用与第一音频设备100建立连接的耳机进行播放。
如果第一音频设备100检测到BLE音频广播功能未打开，第一音频设备100按照现有技术检测是否连接有耳机，例如有线耳机或者蓝牙耳机。如果第一音频设备100通过数据线连接有有线耳机或者通过蓝牙连接有蓝牙耳机，则第一音频设备100按照现有技术使用连接的耳机播放音频。如果第一音频设备100未连接有耳机，则第一音频设备根据上述PCM文件使用自身的扬声器进行播放。在一些实施例中，第一音频设备100根据上述PCM文件被第一音频设备100自身的扬声器进行播放的过程如下：首先，第一音频设备100读取音频文件的描述信息。音频文件的描述信息包含采样率、时长、声道数。然后，第一音频设备100根据音频文件的描述信息，将数字信号形式的PCM文件转换为模拟信号形式的文件。上述数模转换过程可以是在一个循环中执行，不断取得PCM文件中的数据，加入到输入队列中，进行数模转换，然后再从数模转换后的输出队列中取得输出数据，写入到模拟信号形式的文件中，直至PCM文件读取完毕和数模转换完毕。接下来，第一音频设备100调用自身的扬声器170A将该模拟信号形式的文件进行播放。
在第一音频设备100使用自身的扬声器播放歌名“yesterday once more”对应的音频文件的过程中，如果用户想要将该正在播放的音频文件通过BLE音频广播共享，用户可以在设置应用的界面b、下拉菜单201、上拉菜单202、侧拉菜单203或悬浮菜单204上点击音频广播开关101，则第一音频设备执行步骤S111。
S111、第一音频设备100检测BLE音频广播开关101的点击操作。
S112、响应于BLE音频广播开关101的点击操作，第一音频设备100打开BLE音频广播功能，在第一音频设备100检测到正在使用自身的扬声器播放“yesterday once more”对应的音频文件时，获取“yesterday once more”对应的音频文件的PCM文件当前播放的音频数据位置。
举例说明，当第一音频设备100检测到BLE音频广播开关101的点击操作时，第一音频设备100显示包含播放进度的音乐播放界面，如图6F所示，并且显示“正在进行BLE音频广播yesterday once more”或“正在共享yesterday once more”的提示2021。
在本申请一些可能的实施例中，当第一音频设备100检测到BLE音频广播开关101的点击操作时，第一音频设备100在通知栏中可显示“正在共享yesterday once more”的提示。图6E是本申请实施例提供的一种人机交互界面示意图。如图6E中的a所示，第一音频设备100在运行任意APP时或者在主屏幕界面可响应于用户的操作，显示下拉菜单201和提示2021。当第一音频设备100正在将yesterday once more对应的PCM文件打包为BLE音频广播发送时，第一音频设备100可在提示2021中显示“正在共享yesterday once more”。
在本申请一些可能的实施例中，如图6E中的b所示，当第一音频设备100检测到BLE音频广播开关101的点击操作时，第一音频设备100在负一屏501中(负一屏是指在***的多个桌面屏幕左侧的，用于展示信息的屏幕；其中，桌面屏幕用于放置应用程序或小组 件图标)显示“正在进行BLE音频广播yesterday once more”的提示2021。如图6E中的b所示，负一屏501还显示天气提示2022。
当然，上述“正在进行BLE音频广播yesterday once more”或“正在共享yesterday once more”的提示也可以显示在手机的上拉菜单202、侧拉菜单203、悬浮菜单204、桌面或锁屏界面中，本申请实施例对此不做任何限制。
第一音频设备100检测到自身的扬声器正在播放“yesterday once more”对应的音频文件的1分40秒的数据，则第一音频设备100获取“yesterday once more”音频文件的PCM文件在1分40秒的音频数据位置。打开BLE音频广播功能之后，第一音频设备100可以继续使用自身的扬声器或与第一音频设备100建立连接的耳机进行播放，也可以暂停播放(例如，停止在1分40秒)，直到停止BLE音频广播功能之后再从前述暂停的位置恢复播放，但第一音频设备仍显示音乐播放的进度(可以将BLE音频广播的进度作为播放的进度)。图6F和图6G分别是本申请实施例提供的一种音频播放和广播进度示意图。如图6F所示，播放控件2011和102可仍然显示为播放状态，播放进度控件2014仍将BLE音频广播的进度作为播放的进度显示。第一音频设备100进行BLE音频广播至3分钟时，用户停止BLE音频广播功能，则第一音频设备100使用自身的扬声器或连接的耳机播放“yesterday once more”。第一音频设备100可使用自身的扬声器或连接的耳机从音频进度的3分钟开始播放，也可从音频进度的1分40秒开始播放。如果从音频进度的3分钟开始播放，播放进度控件2014从音频进度的3分钟开始继续显示播放的进度。如果第一音频设备100使用自身的扬声器或连接的耳机从音频进度的1分40秒开始播放，播放进度控件2014从音频进度的1分40秒分钟开始继续显示播放的进度。
例如，如图6G中的a所示，第一音频设备100自身的扬声器或连接的耳机正在播放“yesterday once more”对应的音频文件，例如从0分0秒开始播放。当第一音频设备100自身的扬声器或连接的耳机播放到1分40秒时，第一音频设备100打开BLE音频广播功能，第一音频设备自身的扬声器或连接的耳机在1分40秒暂停播放，并从播放进度的1分40秒位置进行BLE音频广播。第一音频设备100进行BLE音频广播至进度3分钟0秒时，用户停止BLE音频广播功能，则第一音频设备100继续使用自身的扬声器或与第一音频设备100建立连接的耳机从“yesterday once more”的1分40秒开始播放；再例如，如图6G中的b所示，第一音频设备100进行BLE音频广播至歌曲进度3分钟时，用户停止BLE音频广播功能，则第一音频设备100使用自身的扬声器或与第一音频设备100建立连接的耳机从BLE音频广播停止时的已完成广播的音频数据处恢复播放，即第一音频设备100可以继续使用自身的扬声器或与第一音频设备100建立连接的耳机从“yesterday once more”的3分钟0秒开始播放。
在本申请另一些实施例中，第一音频设备100正在播放“yesterday once more”，打开了BLE音频广播功能，则第一音频设备100停止使用自身的扬声器或连接的耳机播放“yesterday once more”。第一音频设备100上播放控件2011可显示为暂停状态，播放进度控件2014显示暂停在BLE音频广播功能被打开时“yesterday once more”播放的进度。例如，前例中，播放进度控件2014显示暂停在1分40秒。当第一音频设备100使用自身的扬声器或连接的耳机播放“yesterday once more”时，播放进度控件2014显示自身的扬声器或连接 的耳机播放的进度。
S113、第一音频设备100将上述PCM文件中播放的音频数据位置开始的数据打包为BLE音频广播发送。
其中，PCM文件打包为BLE音频广播的过程可以参考步骤S109的描述。
本申请实施例中，第一音频设备100在进行BLE音频广播的同时，利用不同的信道广播周期广播。周期广播用来使第二音频设备200和第三音频设备300接收BLE音频广播，参考步骤S114。
S114、第一音频设备100广播周期广播。
关于周期广播的具体描述可以参考周期广播概念的描述。
在通过步骤S101将第二音频设备200上电后，第二音频设备200可检测双击操作，并在检测到双击操作后接收周期广播和BLE音频广播，参考步骤S114～S115。
S115、第二音频设备200检测用户对耳塞外壳的双击操作。
本申请实施例中，加速度传感器检测双击操作的过程参考图4所示出的音频输出设备30的描述。
S116、响应于用户对耳塞外壳的双击操作，第二音频设备200接收周期广播。
第二音频设备200在一定时间段内接收周期广播。第二音频设备200与广播周期广播的设备距离越近，第二音频设备200接收到该周期广播时该周期广播的接收信号强度指示(received signal strength indication，RSSI)越大。用户如果想要使用第二音频设备200接收第一音频设备100的BLE音频广播，会将第二音频设备200靠近第一音频设备100。如果在该时间段内接收到多个周期广播，第二音频设备200获取每个周期广播上携带的RSSI，并找到RSSI最大的周期广播，参考步骤S117。则在第二音频设备200距离第一音频设备100比距离其他音频设备更近时，第二音频设备200找到的RSSI最大的周期广播应是第一音频设备100广播的周期广播。
如果在该时间段内第二音频设备200接收到一个周期广播，第二音频设备200无需获取周期广播上携带的RSSI，直接根据该周期广播接收BLE音频广播。
S117、当第二音频设备200接收到的周期广播是多个时，第二音频设备200获取每个周期广播上携带的RSSI，并找到RSSI最大的周期广播。
S118、第二音频设备200根据RSSI最大的周期广播接收BLE音频广播。
本申请实施例中，在找到RSSI最大的周期广播之后，或者在开始接收BLE音频广播之后，第二音频设备200停止接收周期广播，丢弃除RSSI最大的周期广播以外的周期广播。当RSSI最大的周期广播由第一音频设备100广播时，第二音频设备200根据RSSI最大的周期广播接收的BLE音频广播由第一音频设备100广播。该BLE音频广播为第一BLE音频广播。
可以理解的，本申请实施例以检测BLE音频广播的RSSI为例进行介绍，但是本申请实施例不限于该参数，还可以是其他的参数，例如服务质量(quality of service，QoS)或者信噪比(signal to noise ratio，SNR)。
S119、第二音频设备200将第一BLE音频广播转换为音频并进行播放。
具体的，第二音频设备200提取BLE音频广播的BIS数据包。然后，第二音频设备200 将BIS数据包进行数模转换得到模拟信号形式的音频数据。最后，第二音频设备200将该模拟信号形式的音频数据转换为音频播放。
在第二音频设备200将BLE音频广播转换为音频并进行播放过程中，用户如果想要停止第二音频设备200播放音频，可以在第一音频设备100上操作来停止，也可以在第二音频设备200上操作来停止。
具体的，在第二音频设备200正在执行步骤S119时，用户可以在第一音频设备100找到并点击BLE音频广播开关101，来关闭BLE音频广播功能。BLE音频广播开关101处于开启状态，第一音频设备100响应于用户对BLE音频广播开关101的点击操作，关闭BLE音频广播功能。即停止将PCM文件承载在BLE音频广播上。则第二音频设备200无法接收到第一BLE音频广播，进而停止播放音频。
在本申请一些实施例中，在第二音频设备200正在执行步骤S119时，用户还可以在第一音频设备100找到并点击播放控件2011，来停止第二音频设备200播放音频。播放控件2011处于播放状态，第一音频设备100响应于用户对播放控件2011的点击操作，停止进行BLE音频广播。则第二音频设备200无法接收到第一BLE音频广播，进而停止播放音频。
在第二音频设备200将BLE音频广播转换为音频并进行播放过程中，第二音频设备200可以响应于用户对第二音频设备200的关机操作，将第二音频设备200关机，关机后，第二音频设备200停止接收BLE音频广播。第二音频设备200还可以响应于用户对第二音频设备200的耳塞外壳的连续三次点击操作，停止接收第一BLE音频广播，进而停止播放音频。
可以理解的，耳塞外壳的连续三次点击操作来停止接收BLE音频广播仅用于解释本申请实施例。停止接收BLE音频广播还可以是其他用户操作触发的，例如语音、触摸操作等。
与第二音频设备200类似，在通过步骤S102将第三音频设备300上电后，第三音频设备300可检测按压操作，并在检测到按压操作后接收周期广播和BLE音频广播，参考步骤S117～S118。
S120、第三音频设备300检测用户对耳塞外壳的按压操作。
S121、响应于用户对耳塞外壳的按压操作，接收周期广播，并接收第一BLE音频广播，将第一BLE广播转换为音频播放。
当第三音频设备300接收的周期广播是多个时，第三音频设备300获取每个周期广播上携带的RSSI，并找到RSSI最大的周期广播，即第一BLE音频广播。根据周期广播接收BLE音频广播。将接收到的BLE音频广播转换为音频并进行播放。可以参考前述S116-S119的描述。本申请实施例中，压力传感器检测按压操作的过程可以参考图4所示出的音频输出设备30的描述。
本申请实施例中，当第一音频设备100进行第一BLE音频广播时，第二音频设备200和第三音频设备300均接收第一BLE音频广播转换为音频播放。第二音频设备200和第三音频设备300根据第一音频设备100发送的周期广播同步接收BLE音频广播，进行音频播放，以实现音频同步播放。
在一种可能的实现方式中，在步骤S121中，如果用户发现第三音频设备300播放的音频不是用户想要播放的音频，用户可以重新执行按压操作来重新接收BLE音频广播。例如 用户想要播放的音频是来自第一音频设备100以外的设备(如设备A)的音频，在步骤S121中第三音频设备300播放的音频来自第一音频设备100。则用户可以在第三音频设备300播放来自第一音频设备100的音频时，重新执行按压操作。如果用户将第三音频设备300置于距离设备A更近的位置，第三音频设备300重新响应于该按压操作，找到的RSSI最大的周期广播应是设备A广播的，参考步骤S122。
该重新执行按压操作即为第三设定操作。第三设定操作还可以是其他用户操作，例如语音、触摸操作等。
S122、响应于用户对耳塞外壳执行的按压操作，第三音频设备300重新接收周期广播，并接收第二BLE音频广播，将第二BLE广播转换为音频播放。
当第三音频设备300在一定时间段内接收到的周期广播是多个时，第三音频设备300获取这多个周期广播中每个周期广播上携带的RSSI，并重新找到RSSI最大的周期广播。
若重新接收的周期广播只有一个，且为与该第一周期广播不同的第二周期广播，接收该第二周期广播对应的BLE广播的至少一个音频数据包，将该第二周期广播对应的BLE广播的至少一个音频数据包转换为音频进行播放。
若重新接收的周期广播有至少两个，重新接收的至少两个周期广播中RSSI最大的是第三周期广播；如果该第三周期广播与该第一周期广播不同，接收该第三周期广播对应的BLE广播的至少一个音频数据包，将该第三周期广播对应的BLE广播的至少一个音频数据包转换为音频进行播放。或者，如果该第三周期广播与该第一周期广播不是来自同一个设备，接收该第三周期广播对应的BLE广播的至少一个音频数据包，将该第三周期广播对应的BLE广播的至少一个音频数据包转换为音频进行播放。
步骤S121中找到的RSSI最大的周期广播为第一周期广播。在一种可能的实现方式中，第三音频设备300在找到第三周期广播后，检测第三周期广播和第一周期广播是否来自同一个设备。如果检测到第三周期广播和第一周期广播来自同一个设备，第三音频设备300检测本次按压操作(步骤S122中检测到的按压操作)和上次检测到按压操作(步骤S121中检测到的按压操作)之间的时间间隔是否小于或等于时间阈值(例如1分钟)。如果本次按压操作和上次检测到按压操作之间的时间间隔小于或等于1分钟，第三音频设备300从步骤S122中的多个周期广播中接收RSSI仅次于第三周期广播的广播。如果检测到第三周期广播和第一周期广播不是来自同一个设备，或者来自同一个设备但本次按压操作和上次按压操作之间的时间间隔大于1分钟，第三音频设备300根据第三周期广播接收BLE音频广播，并进行音频播放。这样，用户可以通过按压操作找到想要收听的BLE音频广播。
其中，该时间阈值为第一阈值，第一阈值不限于示例1分钟，还可以是其他时长。
在本申请的另一些实施例中，第三音频设备300在找到第三周期广播后，检测第三周期广播和第一周期广播是否为同一个广播。如果检测到第三周期广播和第一周期广播是同一个广播，第三音频设备300检测本次按压操作(步骤S122中检测到的按压操作)和上次检测到按压操作(步骤S121中检测到的按压操作)之间的时间间隔是否小于或等于时间阈值(例如1分钟)。如果本次按压操作和上次检测到按压操作之间的时间间隔小于或等于1分钟，第三音频设备300从步骤S122中的多个周期广播中确定第三周期广播。如果检测到第三周期广播和第一周期广播不是同一个广播，或者是同一个广播但本次按压操作和上次 按压操作之间的时间间隔大于1分钟，第三音频设备300根据第三周期广播接收BLE音频广播，并进行音频播放。
可以理解的，触发第二音频设备200和第三音频设备300接收周期广播的指令不限于上述用户对耳塞外壳的双击操作和按压操作，还可以是其他用户操作，例如语音、触摸操作等。该触发第二音频设备200和第三音频设备300接收周期广播的指令即为第一设定操作。
本申请实施例中，第一操作包含用户对BLE音频广播开关101的点击操作，来开启该BLE音频广播开关。第二操作包含用户对歌名对应的播放控件的点击操作。第二操作还包含对歌名的点击操作。第一周期广播包含接收到至少两个周期广播时，该至少两个周期广播中质量最优的一个。第一周期广播还包含图12所描述实施例中，用户点击的设备标识“MATE20 PRO”对应的周期广播。
上述音频共享的场景中，无需建立第一音频设备100与第二音频设备200、第三音频设备300之间的通信连接，音频数据由第一音频设备100单向传输给音频输出设备30，从而可以简化来自第一音频设备100的音频信号共享的操作流程，提高音频共享的便利性。
上述示例以第二音频设备和第三音频设备为蓝牙耳机进行介绍，但是本申请实施例对此不作限定，第二音频设备和第三音频设备还可以是包含检测并接收BLE音频广播功能的其他音频输出设备，例如音箱。
在一些实施例中，用户还可以进入手机上的播放器的音频播放界面c，在音频播放界面c上找到并点击分享控件进入分享界面。在分享界面找到并打开BLE音频广播标识，来打开BLE音频广播功能。具体的，图7是本申请实施例提供的一种音频共享方法的流程示意图。如图7所示，在图5示出的音频共享方法中步骤S105之后，该音频共享方法还包括步骤S201～S209。S201、第一音频设备100检测歌名“yesterday once more”对应的分享控件的点击操作。
