如图3(a)所示，用户从显示屏的顶部沿着箭头方向向下拉，手机检测到用户的下拉操作。如图3(b)所示，手机响应于该下拉操作，显示控制中心界面30。用户点击控制中心界面30右上角的编辑按钮301。如图3(c)所示，手机响应于用户点击编辑按钮301，手机上显示编辑框302，编辑框302上显示“显示超级终端”选项303。用户点击显示“显示超级终端”选项303。如图3(d)所示，手机响应于用户点击“显示超级终 端”选项303，手机上呈现超级终端卡片304。超级终端卡片304用于显示手机附近可被发现的电子设备。
在一些实施例中，若检测到当前的手机未满足作为发现设备条件时，可以在超级终端卡片304上进行提示。如手机尚未登录华为账号，如图3(e)所示，在超级终端卡片304上提示“点击登录华为账号，搜索附近我的设备，可与其建立协同”。若手机尚未开启蓝牙，如图3(f)所示，在超级终端卡片304上提示“点击开启蓝牙，搜索附近我的设备，可与其建立协同”。
如图3(g)所示，手机满足作为发现设备的条件，用户点击超级终端卡片304上的搜索图标305。手机响应于用户点击搜索图标305，手机可搜索附近的被发现设备(华为平板、华为电脑、智慧屏、音箱和耳机等)，并在超级终端卡片304上显示“正在搜索附近我的设备”。如图3(h)所示，在超级终端卡片304上呈现附近搜索到的华为平板、华为电脑、智慧屏、音箱和耳机对应的显示标识，即呈现华为平板、华为电脑、智慧屏、音箱和耳机对应的设备图标(如平板图标308、电脑图标309、智慧屏图标310、音箱图标311和耳机图标312)。其中，华为平板、华为电脑、智慧屏、音箱和耳机等电子设备的显示标识均不一样，即华为平板、华为电脑、智慧屏、音箱和耳机等电子设备对应的设备图标均不一样。用户想要将手机上的音频数据传输至华为电脑上播放，如图3(i)所示，用户点击电脑图标309。手机响应于用户点击电脑图标309，建立与华为电脑的连接。如图3(j)所示，手机上显示手机与华为电脑接续中，可以协同工作。
在一些实施例中，在手机上呈现如图3(d)所示的超级终端卡片304后，如图3(k)所示，用户可以点击超级终端卡片304上右上角的按钮306。如图3(l)所示，手机响应于用户点击按钮306，在手机上显示超级终端界面307。超级终端界面307上显示附近搜索到的华为平板、华为电脑、智慧屏、音箱和耳机对应的显示标识，即呈现华为平板、华为电脑、智慧屏、音箱和耳机对应的设备图标(平板图标308、电脑图标309、智慧屏图标310、音箱图标311和耳机图标312)，还显示该手机对应的设备图标(手机图标313)，手机图标313位于超级终端界面307上中心。如图3(m)所示。用户将华为电脑对应的设备图标(电脑图标309)拉至靠近手机图标313。如图3(n)所示，手机响应于用户将电脑图标309拉至与手机图标313靠近，手机上显示的电脑图标309与手机图标313图标高亮，表示该手机与华为电脑已建立连接，可以协同工作。在建立与华为电脑的连接后，手机将音频数据(如正在播放的音乐)传输至华为电脑。如图3(o)所示，华为电脑播放该音乐并显示该音乐的界面(即手机播放该音乐的界面)。也即手机将其上正在播放的音乐切换至华为电脑，由华为电脑播放该音乐。华为电脑上的音量进度条314上显示华为电脑当前的音量为100％。
在上述实施例中，华为电脑当前的音量为100％，用户并不知道华为电脑当前的音量为100％。用户将手机上的音频传输至华为电脑，则华为电脑会以其100％大小的音量播放音频，若用户当前处于一个较为安静的环境，这将产生刺耳的干扰，造成不愉快的听觉体验。
鉴于此，本申请实施例提供了一种音量控制方法，音频数据在电子设备间流转前，即电子设备A将音频数据传输至电子设备B前，在电子设备A上提示电子设备B当前的音量，即第一音量。用户根据提示可以设置一个第二音量。电子设备A与电子设备B之 间建立连接，将第二音量传输给电子设备B，以使得电子设备B将其音量设置为第二音量。电子设备A传输音频数据给电子设备B，电子设备B可以根据第二音量播放音频数据。由此，电子设备A通过提示电子设备B的音量，可以方便用户了解待播放音频数据的电子设备B的音量。电子设备A还提供修改电子设备B音量的能力，方便用户可以根据自身需要控制电子设备B播放音频的音量，避免将音频数据传输至电子设备B上播放时，因电子设备B的音量过大造成干扰，给音频分享带来全新体验。
请参阅图4，图4为本申请实施例提供的一种音量控制方法。
步骤S41：第二电子设备向第一电子设备传输第一音量。
在本申请实施例中，第二电子设备获取其自身的音量大小，即第一音量。在第一电子设备与第二电子设备建立连接之前，或者说第一电子设备传输音频数据至第二电子设备之前，第二电子设备向第一电子设备传输第一音量，如第二电子设备向第一电子设备广播其第一音量。
本申请实施例中的音量可以是***音量(master volume)，***音量可以理解为影响着电子设备所有声音的音量。***音量可以写到声卡，控制电子设备所有声音的音量。也可以不写到声卡，而是作为一个乘数因子来影响电子设备所有声音的音量。换句话说，设置***音量即设置所有的应用音量(AudioTrack volume)和流音量(stream volume)。其中，某一应用设置AudioTrack volume时，则仅影响该应用的音量。流音量即某一音频流的音量，即某一音频流设置stream volume时，则仅影响该音频流的音量。
在一些实施例中，音量可以是流音量，其中，音频流(stream)的音量包括但不限于多媒体(media)音量、通话(call)音量、通知(notification)音量和警告(alarm)音量。其中，播放视频的音量可以属于多媒体音量；微信消息的音量可以属于通知音量；闹铃响铃的音量可以属于警告音量。
需要说明的是，本申请实施例中音量对应的音频设备包括但不限于声卡(Sound Card)、扬声器(speaker)、耳机(headset)和蓝牙设备等等。
在本申请实施例中，音量可以用音量比值表示(百分比)表示。该百分比表示该音量对应的播放音量与电子设备的最大播放音量的比例关系。其中，音量对应的百分比越大，该音量对应的播放音量越大，音量对应的百分比越小，该音量对应的播放音量越小。例如，音量50％的播放音量为电子设备的最大播放音量的一半。
在一些实施例中，音量可以用具体数值表示。该具体数值表示该音量对应的播放音量与电子设备的最大播放音量的相对关系。其中，音量对应的数值越大，该音量对应的播放音量越大，音量对应的数值越小，该音量值对应的播放音量越小。例如，音量的数值为200对应的播放音量为最大播放音量，音量的数值为50对应的播放音量为最大播放音量的25％。
在一些实施例中，音量可以用分贝(dB)表示。例如，音量为30dB。
在一些实施例中，将音量大小设置为0-N个等级，音量可以用等级表示。其中，音量的取值为0时表征静音状态，音量的等级越大表征音量越大。需要说明的是，将N的取值大小以及音量大小的划分可由用户根据需要自行设置，比如将N设置为5，则音量一共分为六个等级，分别为0级-静音、1级(静音-最大播放音量的20％大小)、2级(最大播放音量的21％大小-最大播放音量的40％大小)、3级(最大播放音量的41％大小-最大播放音量的60％大小)、4级(最大播放音量的61％大小-最大播放音量的80％大小)、5级(最大播放音量的81％大小- 最大播放音量)。其中，音量大小除了以百分比的形式进行表示外，还可以通过分贝的形式进行表示，本申请实施例对此不进行具体限定。以N＝5为例，在存储等级与音量大小之间的对应关系时，可采取下述表1所示的格式：
表1
音量大小 等级
静音 0
静音-最大播放音量的20％大小 1
最大播放音量的21％大小-最大播放音量的40％大小 2
最大播放音量的41％大小-最大播放音量的60％大小 3
最大播放音量的61％大小-最大播放音量的80％大小 4
最大播放音量的81％大小-最大播放音量 5
在本申请实施例中，上述音量的各种表示方式之间可以进行转换，示例性地，音量百分比与分贝之间的转换关系如下表2：
表2
百分比(％) 分贝(dB)
10 20
20 30
30 40
40 50
示例性地，第二电子设备可以通过函数getMasterVolume获取当前其自身的音量，即第一音量，然后在通信协议的自定义拓展字段中添加关于第一音量的信息，并对外广播。其中，通信协议包括但不限于蓝牙低功耗(Bluetooth Low Energy，BLE)协议、受限制的应用协议(Constrained Application Protocol，CoAP)。
在本申请实施例中，第二电子设备对外广播其对应的第一音量的同时还可以对外广播其对应的设备标识。第一电子设备接收到广播，可以知道该第二电子设备对应的设备标识以及第一音量。其中设备标识用于唯一标识第二电子设备，即每一第二电子设备的设备标识均是唯一的，各个第二电子设备的设备标识不同。其中，设备标识可以为互联网协议地址(Internet Protocol Address，IP地址)或设备号等。
可以理解，第二电子设备的数量包括多个时，各个第二电子设备均可以获取其对应的第一音量。任一第二电子设备均可以通过广播方式向第一电子设备广播其对应的第一音量以及设备标识。任一第二电子设备，其设备标识与其第一音量关联。第一电子设备接收到多个第二电子设备的广播时，其可以获得各个第二电子设备的设备标识以及与该设备标识关联的第一音量。
下述以音量为***音量，并以百分比形式表示音量进行说明。
步骤S42：第一电子设备获取第二电子设备的第一音量，并显示该第一音量。

可以理解，显示标识还可以实现为符号、文字和控件等中的一种或多种，本申请对显示标识的具体形式不作具体限定。
在一些实施例中，可以预先为不同音量大小的音量设置对应的显示方式。第一电子设备可以以不同的显示方式分别显示多个音量大小不同的音量。第一电子设备显示第一音量时，可以根据第一音量确定该第一音量对应的显示方式，然后根据对应的显示方式显示该第一音量。第一电子设备以不同的显示方式分别显示多个音量大小不同的第一音量，通过不同的显示方式区分第一音量的音量大小，可以告知用户所显示的各个第一音量的音量大小不同。通过显示方式可以告知用户第二电子设备当前的第一音量是否适合播放音频。若第二电子设备 的第一音量过大，第一电子设备还可以提示用户修改第二电子设备的音量。
在本申请实施例中，可以根据实际情况将第一音量的音量大小划分出不同范围，并对不同范围设置对应的显示方式。示例性地，音量大小以百分比表示，将音量大小划分为四个范围，第一范围为：大于或等于0，且小于25％，对应第一种显示方式。第二范围为：大于或等于25％，且小于50％，对应第二种显示方式。第三范围：大于或等于50％，且小于75％，对应第三种显示方式。第四范围：大于或等于75％，且小于或等于100％，对应第四种显示方式。第一种显示方式至第四种显示方式均不同。

在一些实施例中，显示方式可以实现为音量图标，第一音量的不同显示方式可以表现为音量图标的区别。以音量图标在超级终端界面上显示为线条形式，则不同长度的线条代表不同音量图标，不同长度的线条代表不同显示方式也即代表不同音量范围(或音量大小)。或不同颜色的线条代表不同音量图标，不同颜色的线条代表不同显示方式也即代表不同的音量范围(或音量大小)。或不同数量的线条代表不同音量图标，不同数量的线条代表不同显示方式也即代表不同的音量范围(或音量大小)。还可以显示该第一音量对应的数值(如百分比或分贝)，根据数值了解到该第一音量的音量大小。可以理解，音量图标的表现形式，以及音量图标的区分显示不限于上述描述，本申请实施例对此不作具体限定。
在一些实施例中，第一电子设备可以将属于同一第二电子设备的显示标识与第一音量关联显示。通过关联显示，用户可以知道该显示标识所对应的第二电子设备的第一音量。如第二电子设备的显示标识为A，对应的第一音量为B。第一电子设备将A与B关联显示，则用户可以知道显示标识A对应的第二电子设备的第一音量为B。
在本申请实施例中，在第一电子设备接收到多个第二电子设备的广播时，可以将该多个第二电子设备的显示标识显示在不同的显示区域。显示标识与第一音量关联显示可以实现为，将第一电子设备的显示界面如超级终端界面划分成多个显示区域，每一第二电子设备唯一对应一显示区域，将属于同一第二电子设备的设备图标与音量图标显示在该第二电子设备所对应的显示区域内，即将属于同一第二电子设备的设备图标与音量图标靠近显示在该第二电子设备所对应的显示区域内。
第一电子设备附近具备广播能力的第二电子设备均可以广播其设备标识与第一音量。在超级终端场景中，第一电子设备接收到符合被发现设备条件的第二电子设备的广播信息，其显示该第二电子设备的设备标识与第一音量。可以理解，在其他场景中，第一电子设备接收到第二电子设备的广播信息后，即可以显示该第二电子设备的设备标识与第一音量，对第二电子设备不作具体限定。
示例性地，以第一电子设备为手机，音量图标为围绕在设备图标外周的线条，不同线条长度代表不同音量大小为例。用户可以参照上述图3(g)操作，搜索手机附近的第二电子设备，接收附近第二电子设备广播的广播信息。请参阅图5，手机接收得到附近第二电子设备(平板、华为电脑、耳机、音箱和智慧屏)的广播信息，在超级终端界面500上显示平板对应的显示标识和第一音量，即显示平板图标501以及围在平板图标501周围的第一音量图标 502。在超级终端界面500上显示华为电脑对应的显示标识和第一音量，即显示电脑图标503以及围在电脑图标503周围的第一音量图标504。在超级终端界面500上显示耳机对应的显示标识和第一音量，即显示耳机图标505以及围在耳机图标505周围的第一音量图标506。在超级终端界面500上显示音箱对应的显示标识和第一音量，即显示音箱图标507以及围在音箱图标507周围的第一音量图标508。在超级终端界面500上显示智慧屏对应的显示标识和第一音量，即显示智慧屏图标509以及围在智慧屏图标509周围的第一音量图标510。在超级终端界面500上还显示手机图标511，手机图标511位于超级终端界面500的中心。如图5所示，各个第二电子设备对应的设备图标与音量图标分别显示在超级终端界面500上的不同显示区域。针对每一第二电子设备，其设备图标与音量图标靠近显示。
图5与图3(l)的区别在于还显示各个第二电子设备所广播的第一音量，即显示围绕各个设备图标的周围的第一音量图标。以第一音量图标的长度围绕设备图标一周代表音量大小100％。第一音量图标502的长度为刚好围绕平板图标502外周的一半，则第一音量图标502代表平板的第一音量为50％。第一音量图标504的长度为刚好围绕电脑图标503外周的四分之三，则第一音量图标504代表电脑的第一音量为75％。第一音量图标506的长度为刚好围绕耳机图标505外周的一半，则第一音量图标506代表耳机的第一音量为50％。第一音量图标508的长度为刚好围绕音箱图标507外周一圈，则第一音量图标508代表音箱的第一音量为100％。第一音量图标510的长度为刚好围绕智慧屏图标509外周一圈，则第一音量图标510代表智慧屏的第一音量为100％。
其中，如图5所示，第一音量图标508和第一音量图标510均代表音量为100％，则第一音量图标508和第一音量图标510的线条填充是一样。第一音量图标502和第一音量图标506均代表音量为50％，则第一音量图标502和第一音量图标506的线条填充是一样。第一音量图标504与第一音量图标508的线条填充不同，第一音量图标504与第一音量图标502的线条填充不同。
在一些实施例中，音量图标除了表现线条的填充样式不同如图5所示，音量图标还可以表现为颜色不同。如第一音量图标508和第一音量图标510的线条颜色均为红色。第一音量图标502和第一音量图标506的线条颜色均为绿色。第一音量图标5041线条颜色为黄色。
在一些实施例中，对于音量百分比小于50％的第一音量，音量图标的颜色线条为绿色，代表音量大小合适。对于音量百分比为50％至80％的第一音量，音量图标的颜色线条为黄色，代表音量略大，可能会对环境产生干扰。对于音量百分比为大于80％的第一音量，音量图标的颜色线条为红色，代表音量过大，会对环境产生干扰。
可以理解，手机接收得到附近第二电子设备的广播信息，也可以在超级终端卡片上显示接收到的第二电子设备所广播的显示标识和第一音量。在超级终端卡片上显示第二电子设备(或各个第二电子设备)对应的显示标识和第一音量，具体可以参考上述图5在超级终端界面500上显示第二电子设备对应的显示标识和第一音量，在此不再赘述。
步骤S43：第一电子设备接收用户输入的第一操作，其中，第一操作用于设置第二电子设备的第二音量。
在本申请实施例中，在步骤S42中，第一电子设备将接收到的各个第二电子设备所广播的第一音量显示出来后，用户可以看到各个第二电子设备对应的第一音量。第一电子设备还提供音量控制能力，该音量控制能力可以为用户提供控制第二电子设备音量的功能。用户使 用该音量控制能力，可以根据自身需求去设置或调节第二电子设备的音量，即用户可以通过第一电子设备提供的音量控制能力，控制第二电子设备以用户期望的音量播放音频。如用户在第一电子设备上输入第一操作，第一电子设备响应于该第一操作得到第二音量，该第二音量为用户希望第二电子设备播放音频时所使用的音量，或用户希望第二电子设备依据该第二音量去设置播放音频时所使用的音量，将播放音频时所使用的音量设置为第二音量。
可以理解为，用户看到第二电子设备的音量为第一音量对应的音量大小后，用户想要重新设置第二电子设备的音量，用户输入第一操作，该第一操作用于将第二电子设备的音量由第一音量对应的音量大小设置为第二音量对应的音量大小。
需要说明的是，若第一音量为***音量，则第二音量也为***音量。若第一音量为某一音频流音量，则第二音量也为该音频流音量。
需要说明的是，在第二音量生效前，第二电子设备的实际音量仍为第一音量，该第二音量可以理解为存储至第一电子设备上的临时修改音量。示例性地，用户可以在手机上输入第一操作，将平板对应的第一音量H设置为第二音量A，然后又将第二音量A修改为第二音量B，最后又将第二音量B修改为第二音量C，第一电子设备可以将第二音量A、第二音量B和第二音量C均存储至本地，或，仅存储当前最新设置的第二音量C。在第二音量C未生效前(如未将第二音量C传输给平板前)，平板播放音频的音量仍为第一音量H。
在本申请实施例中，第二音量生效可以理解为第二电子设备可以依据该第二音量播放音频。第二音量生效的时间可以在第一电子设备与第二电子设备建立连接时、第一电子设备将第二音量传输给第二电子设备时、第一电子设备将第二音量传输给第二电子设备后、第一电子设备将第二音量和音频数据传输给第二电子设备时、第一电子设备将第二音量和音频数据传输给第二电子设备后或第一电子设备将第二音量传输给第二电子设备后，第一电子设备将音频数据传输给第二电子设备前。
在本申请实施例中，第一电子设备可以实时响应于用户的第一操作得到第二音量，并实时显示用户当前设置的最新的第二音量。通过实时显示用户设置的最新的第二音量，便于用户了解当前为第二电子设备所设置的第二音量。
在本申请实施例中，第一电子设备可以告知用户该第二音量是临时的、未生效的，还可以告知用户在设置好第二电子设备的第二音量后，若在预设时间内所设置的第二音量未生效，则该第二音量将不显示，恢复显示第二电子设备对应的实际音量即第一音量。
在一种可能实现方式中，第一电子设备可以通过提示告知用户该第二音量是临时的、未生效的，还可以通过提示告知用户在预设时间内所设置的第二音量未生效，则该第二音量将不显示，恢复显示第二电子设备对应的实际音量即第一音量。示例性地，第一电子设备在显示第二音量时，将上述提示呈现在界面上，该提示在界面上可以表现为显示提示框、音量区分标识和第一音量与第二音量不同的显示方式中的一种或多种。其中，提示框内显示相应的文字以起到提示用户的作用。音量区分标识为用于区分第一音量与第二音量的标识，通过音量区分标识便于用户可以区分出第一音量与第二音量，进而了解到第一音量为实际音量，第二音量为未生效的临时修改音量。第一音量与第二音量不同的显示方式即第二音量以区别于第一音量显示方式进行显示的显示方式。如以第一显示方式显示第一音量，以不同于第一显示方式的第二显示方式显示第二音量，通过不同显示方式(第一显示方式和第二显示方式)可以便于用户区分出第一音量与第二音量，进而了解到第一音量为实际音量，第二音量为未 生效的临时修改音量。本申请实施例对提示的表现形式不作具体限定。
在一些实施例中，可以在电子设备初次使用音量区分标识或使用第一音量与第二音量不同的显示方式作为提示时，一并呈现提示框告知用户音量区分标识或该不同的显示方式的提示意义，以便用户可以在下回看到用音量区分标识或不同的显示方式，了解到第一音量是实际音量，第二音量为未生效的临时修改音量。
在本申请实施例中，第一电子设备提供给用户的音量控制能力中进行音量设置的模式包括手动设置模式。在手动设置模式下，该第一操作用于根据用户的意愿直接设置第二电子设备的第二音量的数值，第一电子设备接收用户输入的第一操作，根据第一操作所指示的音量大小设置第二电子设备的第二音量，即第二音量的具体数值是由用户输入的。手动设置模式下的第一操作可以包括滑动、点击、长按、键盘输入或按压第一电子设备的音量键等，本申请对第一操作的具体表现形式不作具体限定。
示例性地，以用户在图5的超级终端界面500上输入第一操作，上述提示表现为显示提示框，用户在手机的显示屏上滑动来设置第二音量为例。
音量图标均可以编辑。用户想要设置华为电脑的第二音量，用户可以输入第一操作，如用户滑动第一音量图标504，将第一音量图标504的长度滑动至围绕电脑图标503外周的一半，得到如图6(a)所示的第二音量图标601。图6(a)中的第二音量图标601与图5中的第一音量图标504的区别在于，第二音量图标601的长度相对于第一音量图标504的长度变短，且第二音量图标601还包括箭头602。该箭头602代表当前第二音量图标601处于音量设置状态，也即该第二音量图标601所代表的第二音量尚未生效，仍处于编辑状态，第二音量图标601可以根据用户的滑动改变其长度。如图6(b)所示，用户松开对手机显示屏的触控，手机检测到用户释放滑动操作，手机上显示第二音量图标603，第二音量图标603代表华为电脑的第二音量为50％。图6(b)中的第二音量图标603与图6(a)中的第二音量图标601区别在于：第二音量图标603没有箭头602，即代表当前华为电脑的第二音量设置完毕。如图6(b)所示，在超级终端界面500上还可以显示提示框604，提示框604可以显示在第二音量图标603附近。该提示框604上显示“第二音量50％尚未生效”、“第二音量50％为临时修改音量”或“若在十秒内第二音量50％未生效，则将恢复显示第一音量75％”。其中提示“若在十秒内第二音量50％未生效，则将恢复显示第一音量75％”，即代表在预设时间10秒内，设置的第二音量50％未生效，则该第二音量图标603将消失，将在电脑图标503外周显示第一音量图标504。也即如图6(b)所示设置好的第二音量后，经过十秒该第二音量未生效，则刷新超级终端界面500如图5所示。
示例性地，以用户在图5的超级终端界面500上输入第一操作，上述提示表现为音量区分标识，用户通过键盘输入第二音量为例。
第一电子设备可以提供音量设置窗口，用户输入的第一操作可以包括多个子操作。如图7(a)所示，手机上显示电脑图标503以及围绕在电脑图标503外周的第一音量图标504。用户想要设置华为电脑的第二音量，用户输入第一操作包括用户点击电脑图标503，手机响应用户点击电脑图标503，在超级终端界面500上显示音量设置窗口701。音量设置窗口701上显示华为电脑当前的音量，音量设置窗口701上显示音量百分比％为75，即当前华为电脑的第一音量为75％。如图7(b)所示，用户输入第一操作还包括用户选中音量设置窗口701内“75”，音量设置窗口701内“75”被选中后，在超级终端界面500上显示输入键盘702。 如图7(c)所示，用户输入第一操作还包括用户通过输入键盘702输入数字“5”和“0”，设置第二音量为50％，则音量设置窗口701上显示音量百分比％为50。用户若想修改第二音量，可以选中音量设置窗口701内“50”，继续通过输入键盘702输入数字进行修改。若用户退出键盘702，则手机确定第二音量为50％。如图7(d)所示，手机上显示音量图标703。音量图标703与图5第一音量图标504的区别在于：音量图标703增加了起始标识704、第一音量终止标识705和第二音量终止标识706。起始标识704与第一音量终止标识705分别用于指示第一音量的起始与终止。起始标识704与第一音量终止标识705之间线条长度代表第一音量为75％。起始标识704与第二音量终止标识706分别用于指示第二音量的起始与终止。起始标识704与第二音量终止标识706之间线条长度代表第二音量为50％。
上述起始标识704、第一音量终止标识705和第二音量终止标识706均不同，可以表现为不同的箭头，本申请对此不作具体限定。
示例性地，以用户在图5的超级终端界面500上输入第一操作，上述提示表现为第一音量与第二音量不同的显示方式，用户通过按压第一电子设备的音量键设置第二音量为例。
如图8(a)所示，手机上显示电脑图标503以及围绕在电脑图标503外周的第一音量图标504。用户想要设置华为电脑的第二音量，用户输入第一操作包括用户长按电脑图标503。手机响应用户长按电脑图标503，在手机超级终端界面500上显示音量进度条801。音量进度条801上填充区域占音量进度条801整个区域的四分之三，代表华为电脑当前的音量即第一音量为75％。用户可以按压手机的音量键802的音量“+”键和音量“-”键来设置第二音量。如图8(b)所示，用户输入第一操作还包括用户按压音量“-”键，调整音量进度条801上填充区域占音量进度条801整个区域的一半，即将音量调整为50％，代表当前设置的第二音量为50％。用户松开对音量键802的按压，手机检测到用户对音量键802按压的释放，获取最终设置的音量“50％”，将该音量“50％”作为第二音量。如图8(c)所示，根据设置的第二音量“50％”显示第二音量图标803，第一音量图标504与第二音量图标803同时显示在电脑图标503附近。第一电子设备区分显示第一音量与第二音量，以第一显示方式(第一音量图标504)显示第一音量，以第二显示方式(第二音量图标803)显示第二音量，第一音量图标504和各自的线条不同。第一音量图标504与第二音量图标803分开显示，即第二音量图标803的显示并不会覆盖第一音量图标504的显示，代表临时修改音量并不会覆盖第二电子设备的真实音量。第二音量图标803线条长度为刚好围绕电脑图标503外周的一半，即代表第二音量为50％。
需要说明的是，本申请对此第一操作的具体形式、第一音量图标、第二音量图标以及上述提示的显示形式不作具体限定。
在一种可能实现方式中，第一电子设备提供给用户的音量控制能力中进行音量设置的模式包括自动设置模式。在自动设置模式下，第一电子设备接收用户输入的第一操作，响应于第一操作根据预设规则设置第二音量。即第二音量的具体数值并非是由用户当下直接输入的。自动设置模式下的第一操作可以包括滑动、点击、双击、长按或手势(如画圈手势)等。
在一些实施例中，第一电子设备响应于第一操作根据预设规则设置第二音量包括：第一电子设备响应于第一操作，触发第一电子设备的采音设备采集第一电子设备周围环境的环境音，根据该环境音设置第二音量。
在本申请实施例中，用户要将第一电子设备上的音频数据传输至第二电子设备，由第二 电子设备播放该音频数据，可以得到第一电子设备与第二电子设备处于同一环境下。第一电子设备主动去采集周围环境的环境音，采集到的环境音也即第二电子设备周围环境的环境音。其中，环境音可以使用分贝(dB)表示。
在本申请实施例中，第一电子设备根据其采音设备所采集到的环境音设置第二音量。如，周围环境声音很大，采集到的环境音的分贝为85dB，第一电子设备可以设置较大的第二音量，第二电子设备使用较大的第二音量播放音频，以保证用户听到音频。若周围环境声音很小，采集到的环境音的分贝为15dB，第一电子设备可以设置较小的第二音量，以此保证第二电子设备所使用的第二音量能与环境音之间保持舒适的音量，提高用户的听觉体验。示例性地，第一电子设备检测到当前环境的环境音为85dB，为了保证用户能听到音频，可以设置第二音量为比环境音的音量更大，如90dB，也可以根据音量百分比与分贝之间的换算，将90dB换算成音量百分比85％，设置第二音量为85％。
在一些实施例中，也可以预先将不同环境音的音量大小设置不同的等级，并对不同等级设置对应的第二音量。如下表3所示：
表3
环境音的音量大小 等级 第二音量
0dB 0 15dB以下或10％
15dB以下 1 30dB或20％
30dB 2 40dB或30％
40dB 3 60dB或40％
60dB 4 70dB或50％
70dB 5 85dB或60％
85dB 6 95dB或70％
95dB 7 100dB或80％
100dB 8 110dB或90％
110dB 9 120dB或100％
示例性地，以用户在图5的超级终端界面500上输入第一操作，上述提示表现为第一音量与第二音量不同的显示方式，用户长按图标设置第二音量为例。
如图9(a)所示，手机上显示电脑图标503以及围绕在电脑图标503外周的第一音量图标504。用户想要设置华为电脑的第二音量，用户可以输入第一操作，如用户双击电脑图标503。如图9(b)所示，手机响应于用户双击电脑图标503，触发采音设备(如麦克风)采集周围环境的环境音。手机上显示采音状态标识901，该采音状态标识901指示当前手机处于采音状态中。如图9(c)所示，手机获得当前周围环境的环境音的音量大小为60dB，手机依照上述表3设置第二音量为50％。手机上显示音量进度条902，音量进度条902上填充区域占音量进度条902整个区域的一半，代表当前第二音量为50％。第一音量以第一音量图表504表示，第二音量以音量进度条902表示。第一音量图表504和音量进度条902表现形式不同，第一音量图表504以围绕至电脑图标503外周线条长度表达第一音量大小，音量进度条902以填充区域占整个进度条区域的百分比表达第二音量大小。
在一些实施例中，第一电子设备响应于第一操作根据预设规则设置第二音量包括：第一电子设备响应于第一操作确定第一操作所指示的第二电子设备，获取该第二电子设备的音量 记录，根据该音量记录设置第二音量，其中音量记录用于记录该第二电子设备以往所设置过的生效的第二音量。如，第一电子设备可以获取该音量记录中记录次数最多的音量(如10％)，将该记录次数最多的音量设置为当前的第二音量。第一电子设备还可以将音量记录中最新记录的音量(如10％)设置为当前的第二音量。
在本申请实施例中，第一电子设备可以获取每一第二电子设备的设备标识以及其生效的第二音量，将第二电子设备的设备标识与其生效的第二音量关联存储。例如，针对某一第二电子设备，该第二电子设备的设备标识为A，用户先为该第二电子设备设置第二音量为a，然后设置第二音量为b，第二音量b生效。在下一次，用户为该第二电子设备设置第二音量为c，第二音量c生效。第一电子设备可以记录该第二电子设备的音量记录为：设备标识A以及其以往所设置过的生效的第二音量包括第二音量b和第二音量c。第一电子设备还可以记录每一第二音量生效的时间，如第二音量b在时刻T0生效，第二音量c在T1时刻生效，手机可以根据生效时间可以确定最新记录的音量。
示例性地，以用户在图5的超级终端界面500上输入第一操作，上述提示表现为提示框，用户输入画圈手势设置第二音量为例。
如图10(a)所示，手机上显示电脑图标503以及围绕在电脑图标503外周的第一音量图标504。用户想要设置华为电脑的第二音量，用户可以输入第一操作，如用户围绕电脑图标503外周围滑动一圈。如图10(b)所示，手机响应于用户围绕电脑图标503滑动一圈的操作，手机获取该电脑图标503对应的华为电脑的音量记录，该音量记录中最新记录的生效的第二音量为50％。手机将最新记录的第二音量50％设置为第二音量。手机也可以显示提示窗口102，提示窗口102内显示“是否设置为上一次设置的音量50％”以及“是”选项和“否”选项。若用户点击“否”选项，则用户可以选择手动设置，或手机以其他规则设置第二音量，如手机将音量记录中记录次数最多的音量设置为第二音量。若用户点击“是”选项，手机响应用户点击“是”选项设置华为电脑的第二音量为50％。如图10(c)所示，手机上显示提示框103“第二音量50％”，该提示框103还可以显示“尚未生效”。
在一些实施例中，第一电子设备提供给用户的音量控制能力中进行音量设置的模式包括全局设置模式。在全局设置模式下，第一电子设备可以自动对所有的第二电子设备均设置同一第二音量。全局设置模式下的第一操作可以包括触发全局设置控件、输入特定手势等，本申请对第一操作的具体表现形式不作具体限定。
示例性地，用户触发全局设置控件，第一电子设备响应于用户触发全局设置控件，对其接收到的广播信息所对应的所有的第二电子设备设置第二音量，也可以理解为对超级终端界面500上的所显示的所有第二电子设备(如平板、华为电脑、耳机、音箱和智慧屏)设置第二音量。例如，第一电子设备接收到设备A和设备B广播的第一音量以及设备标识，则该接收到的广播信息所对应的所有的第二电子设备即指设备A和设备B。第二音量可以采用上述手动设置模式或自动设置模式进行设置获得。换句话说，在全局设置模式下，用户输入的第一操作不是针对某一第二电子设备设置第二音量，而是针对第一电子设备接收到的广播信息所对应的所有的第二电子设备设置第二音量。
在本申请实施例中，在全局设置模式中，第一电子设备自动为其接收到的广播信息所对应的所有第二电子设备均设置同一第二音量A。在多个第二电子设备均设置第二音量A后，则对于某一第二电子设备，其第二音量生效的时间可以参考上述第二音量生效的时间，在此 不再赘述。
示例性地，以用户在全局设置模式下手动设置第二音量为例。请参阅图11(a)，超级终端界面500上还包括全局设置控件111，本申请对全局设置控件111在界面上呈现形式不作具体限定。用户想要设置第二电子设备的第二音量，用户可以输入第一操作。如图11(a)，用户输入的第一操作可以包括用户点击全局设置控件111。用户点击全局设置控件111后，用户可以采用图6(a)所示的方式设置第二音量。用户输入的第一操作还可以包括用户对任一第二电子设备的音量图标进行调整，用户输入的第一操作还可以包括用户滑动第一音量图标504，将第一音量图标504的长度滑动至围绕电脑图标503外周的一半，则可以得到如图11(b)所示的第二音量图标110，第二音量图标110长度为围绕电脑图标503外周的一半，代表第二音量为50％。在用户设置完第二音量后，如图11(b)所示，手机上可以显示窗口112“是否设置第二音量为50％”以及“是”和“否”选项。其中显示窗口112内还可以显示“是否全局设置第二音量为50％”，显示窗口112显示的内容用于提示用户当前设置的第二音量还可以提示用户当前设置的第二音量为全局设置，本申请对具体显示内容不作具体限定。若用户点击“否”选项，则不对所有第二电子设备(如平板、华为电脑、耳机、音箱和智慧屏)设置第二音量50％。若用户点击“是”选项，确认将所有第二电子设备(平板、华为电脑、耳机、音箱和智慧屏)的第二音量设置为50％。如图11(c)所示，手机显示音量进度条113，音量进度条113标识第二音量为50％，即当前超级终端界面500上所显示的所有的第二电子设备的第二音量为50％。若所有第二电子设备的第二音量均生效，则所有第二电子设备均使用第二音量50％播放音频。
在一些实施例中，用户可以采用图7(a)至图7(c)所示的方式设置第二音量，在用户点击全局设置控件111后，用户输入的第一操作还可以包括用户可以点击任一第二电子设备的设备图标。如图7(a)所示，用户点击电脑图标503，用户输入的第一操作还可以包括用户选中音量设置窗口内“75”后，用户通过输入法键盘输入“50”，设置第二音量为50％。手机获得用户设置的第二音量50％，将所有第二电子设备的第二音量均设置为50％。在一些实施例中，用户可以采用图8(a)至图8(b)所示的方式设置第二音量，在用户点击全局设置控件111后，用户输入的第一操作还可以包括用户可以长按任一第二电子设备的设备图标。如图8(a)所示，用户长按电脑图标503，用户输入的第一操作还可以包括用户按压音量“-”，将音量调整为50％，手机获得用户设置的第二音量50％，将所有第二电子设备的第二音量均设置为50％。用户可以通过上述任一手动设置模式设置第二音量，本申请对此不作具体限定。
在一些实施例中，该全局设置控件可以集合自动设置模式所提供的功能，即用户点击全局设置控件后，第一电子设备可以采用上述自动设置模式设置第二音量。
示例性地，以手机根据环境音设置第二音量为例。如图11(a)所示，用户输入第一操作可以包括用户点击全局设置控件111，在用户点击全局设置控件111后，用户可以采用图9(a)至图9(b)所示的方式设置第二音量。用户输入第一操作还可以包括用户双击任一第二电子设备的设备图标，手机可以显示采音状态标识901。手机获得当前周围环境的环境音，手机依照上述表3根据所获得的环境音的音量大小自动设置第二音量为50％。如图11(d)所示，手机显示提示框114“全局设置第二音量为50％”，告知用户当前所有第二电子设备的第二音量均设置为50％。
在一些实施例中，以手机根据所有第二电子设备的音量记录设置第二音量为例。手机获得所有第二电子设备的音量记录，从这些音量记录中获得记录次数最多的音量或当前最新记录的音量，将记录次数最多的音量或当前最新记录的音量设置为第二音量。例如所有第二电子设备包括设备A和设备B，设备A的音量记录中记录音量a的次数为5次，音量b的次数为4次，设备B的音量记录中记录音量a的次数为2次，音量b的次数为4次，则可以得到记录次数最多的音量为b。
如图12(a)所示，用户顺时针沿着所有第二电子设备的设备图标(平板图标501、电脑图标503、耳机图标505、音箱图标507和智慧屏图标509)滑动一圈，手机检测到用户输入的画圈手势。手机响应于用户的画圈手势，手机获取所有第二电子设备的音量记录，从这些音量记录中可以获得出现次数最多的音量为50％，则可以将该记录次数最多的音量50％确定为第二音量。如图12(b)所示，手机显示提示框121“是否全局设置第二音量为50％”和“是”选项和“否”选项。若用户点击“否”选项，手机可以为用户提供手动设置模式或自动设备模式以供用户继续设置第二音量。用户点击“是”选项，则全局设置第二电子设备的第二音量为50％。用户确定设置所有第二电子设备第二音量为50％。如图12(c)所示，各个第二电子设备上均显示对应的第二音量图标121，该第二音量图标121标识该第二音量为50％。手机上还显示提示框122“第二音量尚未生效，请建立连接”，以引导用户建立连接。可以理解，上述第二音量若未在预设时间内生效，则恢复显示如图12(a)所示的界面。
在一些实施例中，全局设置所有第二电子设备的第二音量后，可以将第二音量与各个第一电子设备的第一音量区分显示。如图13所示，手机上显示平板图标501、围在所述平板图标501周围的第一音量图标502以及第二音量图标131，第二音量图标131指示当前平板的第二音量为50％。手机上显示电脑图标503、围在电脑图标503周围的第一音量图标504以及第二音量图标132，第二音量图标132指示当前电脑的第二音量为50％。手机上显示耳机图标505、围在耳机图标505周围的第一音量图标506以及第二音量图标133，第二音量图标133指示当前耳机的第二音量为50％。手机上显示音箱图标507、围在音箱图标507周围的第一音量图标508以及第二音量图标134，第二音量图标134指示当前音箱的第二音量为50％。手机上显示智慧屏图标509、围在智慧屏图标509周围的第一音量图标510以及第二音量图标135，第二音量图标135指示当前智慧屏的第二音量为50％。手机还显示提示框136，提示框136内显示“第二音量尚未生效，拖拽至本机以建立连接或发起任务接续”，以此指示用户将第二电子设备图标拖拽至手机图标511，以建立连接。步骤S44：第一电子设备接收用户输入的第二操作。
在本申请实施例中，在步骤S43中用户设置第二音量后，用户在第一电子设备上再输入第二操作，该第二操作用于触发第一电子设备建立与第二电子设备之间用于传输第二音量与音频数据的连接，触发第一电子设备将第二音量传输给第二电子设备，以及触发第一电子设备将音频数据传输给第二电子设备。
示例性地，如图8(c)所示，用户设置第二音量为50％后，如图14(a)所示，用户想要将第二音量和音频数据传输给第二电子设备，用户可以输入第二操作，第二操作可以包括用户在超级终端界面500上进行滑动操作，如用户将电脑图标503拖拽至手机图标511所处位置。如图14(b)所示，电脑图标503与手机图标511接触后，电脑图标503与手机图标511处于高亮，显示为华为电脑与手机处于连接状态。在一些实施例中，在手机与电脑建立 连接后，如图14(b)所示，围在电脑图标503周围的第一音量图标504消失，仅显示围在电脑图标503周围的音量图标141。图14(b)与图8(c)的区别在于：电脑图标503与手机图标511贴近，围在电脑图标503周围的第一音量图标504消失，仅显示围在电脑图标503周围的音量图标141。音量图标141的显示方式与第一音量图标504的显示方式可以相似，例如图14(b)中的音量图标141和第一音量图标504的线条形状或填充是相同，区别仅在于音量图标141和第一音量图标504线条的长度是不一样的。音量图标141表示此时第二电子设备即电脑的音量为50％，也即当前第二电子设备的实际音量为50％。
示例性地，如图13所示，用户设置完所有第二电子设备的第二音量50％后，如图15(a)所示，用户点击返回按键1501。如图15(b)所示，手机上显示控制中心界面30，在超级终端卡片304上显示平板图标501以及第二音量图标131，第二音量图标131指示当前平板的第二音量为50％。还显示电脑图标503以及第二音量图标132，第二音量图标132指示当前平板的第二音量为50％。还显示耳机图标505以及第二音量图标133，第二音量图标133指示当前平板的第二音量为50％。还显示音箱图标507以及第二音量图标154，第二音量图标134指示当前平板的第二音量为50％。还显示智慧屏图标509以及第二音量图标155，第二音量图标135指示当前平板的第二音量为50％。如图15(c)所示，用户想要将第二音量与音频数据发送给华为电脑，用户可以在超级终端卡片304上输入第二操作，用户输入第二操作如用户点击电脑图标503，手机响应用户点击电脑图标503建立电脑与手机的连接，则电脑的第二音量50％即将生效。如图15(d)，显示手机与电脑正在建立连接，华为电脑所设置的第二音量50％生效。电脑图标503下显示音量图标151，音量图标151表示经过设置的华为电脑的音量为50％，即当前华为电脑的实际音量为50％。
在一些实施例中，在第一电子设备建立其与第二电子设备之间用于传输第二音量和音频数据的连接前，若该第二电子设备的音量较大，例如高于一定百分比、警戒值、阈值、或高于当前第一电子设备的音量百分比，可以提示用户进行音量设置。
示例性地，用户未设置第二电子设备的第二音量，在第一电子设备建立其与第二电子设备之间用于传输第二音量和音频数据的连接前，第一电子设备检测到该第二电子设备的音量(即第一音量)高于一定百分比、警戒值、阈值、或高于当前第一电子设备的音量百分比，则可以提示用户进行音量设置。如图16(a)所示，用户未对华为电脑设置第二音量，用户将电脑图标503拖拽至靠近手机图标511过程中，手机上显示提示框161“是否需要设置第二音量”、“是”选项和“否”选项，用户点击“否”选项，则用户可以继续将电脑图标503拖拽至靠近手机图标511。若用户点击“是”选项，则用户可以参考上述自动设置模式或手动设置模式设置第二音量。
在一些实施例中，用户设置了第二电子设备的第二音量，在第一电子设备建立其与第二电子设备之间用于传输第二音量和音频数据的连接前，第一电子设备检测到该第二电子设备的音量(即第二音量)高于一定百分比、警戒值、阈值、或高于当前第一电子设备的音量百分比，则可以提示用户进行音量设置。如图16(b)，用户对华为电脑设置了第二音量，用户可以将电脑图标503拖拽至手机图标511处，手机将电脑图标503返回至原处，并显示提示框162，提示框162内显示“当前音量过大，是否需要设置”、“是”选项和“否”选项，若用户点击“否”选项，则手机将电脑图标503拖拽至手机图标511处。若用户点击“是”选项，则用户可以参考上述自动设置模式或手动设置模式设置第二音量。
在一些实施例中，在第二音量设置完成后、第二音量即将生效前、或第一电子设备即将要将第二音量传输给第二电子设备前、或第一电子设备即将与第二电子设备建立连接前，可以显示提示，是否确认当前所设置的第二音量。若用户确认，则第一电子设备将第二音量、音频数据或第二音量与音频数据传输给第二电子设备。
示例性地，如图12(c)所示用户设置好第二音量，并将电脑图标503拖拽至手机图标511后。如图17所示，手机上还可以显示提示框171，提示框171内显示“是否确认设置第二音量为50％”、“是”选项和“否”选项。用户点击“是”选项，则可以继续步骤，如第一电子设备继续建立其与第二电子设备连接、第一电子设备继续将第二音量传输给第二电子设备。若用户点击“否”选项，则用户可以参考上述自动设置模式或手动设置模式对音量设置。
在一些实施例中，如图15(c)用户设置好第二音量，并点击电脑图标503后，可以在超级终端卡片304上显示上述提示框171。
需要说明的是，不限于在用户在超级终端界面500上输入第一操作、第二操作，用户还可以在超级终端卡片304上输入第一操作、第二操作，即如图15(b)所示的超级终端卡片304可以参考上述超级终端界面500显示各个元素或控件，如包括第二电子设备的显示标识、第一音量图标、第二音量图标、全局设置控件以及上述提示等，本申请对此不作具体限定。

又例如，笔记本电脑上可显示预设的二维码，该二维码中包括笔记本电脑的设备信息。那么，手机通过扫描笔记本电脑上的二维码也可获取到笔记本电脑的设备信息。这样，手机按照该设备信息可与笔记本电脑建立蓝牙连接、Wi-Fi连接或P2P连接等连接。
当然，用户也可以使用手机创建Wi-Fi热点，并将笔记本电脑接入手机创建的Wi-Fi热点中，从而建立手机与笔记本电脑之间的连接，本申请实施例对手机与笔记本电脑建立连接的具体方式不做任何限制。
步骤S46：第一电子设备传输第二音量至第二电子设备。
在本申请实施例中，第一电子设备基于其与第二电子设备之间的用于传输第二音量的连接，向第二电子设备传输第二音量。示例性地，第一电子设备可以向第二电子设备发送音量 设置请求，并发送第二音量。
在本申请实施例中，如图17所示，用户确认设置第二音量为50％，则该第二音量50％生效。或在第一电子设备与第二电子设备建立连接时，如图14(b)所示，将该设置了第二音量的电脑图标503拖拽至手机图标511处，则该第二音量50％生效。或如图15(c)用户点击电脑图标503，则设置的第二音量生效。
步骤S47：第二电子设备将其音量设置为第二音量。
在本申请实施例中，第二电子设备可以调用函数setVolume(AudioVolumeType volumeType,int volume)设置第二音量。在第二音量设置完成后，第二电子设备可以响应于第一电子设备发送的音量设置请求，回复音量设置完毕。
步骤S48：第一电子设备传输音频数据至第二电子设备。
在本申请实施例中，第一电子设备基于其与第二电子设备之间的用于传输音频数据的连接，向第二电子设备传输音频数据。
在一些实施例中，若第一电子设备同时向第二电子设备传输第二音量与音频数据，则第二电子设备需等第二音量设置完毕之后再播放音频数据。
在一些实施例中，第一电子设备接收到第二电子设备返回的音量设置完毕的信息后，第一电子设备还可以显示确认信息，如第一电子设备显示“是否确认设置第二音量50％”或显示“是否确认以50％音量播放音频”，若用户选择确认，则第一电子设备再传输音频数据至第二电子设备。
在本申请实施例中，步骤46和步骤S48可以同时进行，或者先进行步骤46后进行步骤S48，或者，先进行步骤48后进行步骤S46，本申请实施例对此不作具体限定。
在一些实施例中，第一电子设备将第二音量随第一电子设备的音频数据传输至第二电子设备。即第一电子设备可以基于步骤S45建立的同一通信通道传输第二音量和第一电子设备的音频数据。
步骤S49：第二电子设备接收音频数据，并使用第二音量播放音频数据。
在本申请实施例中，在步骤S47中，第二电子设备已经设置其当前音量为第二音量，第二电子设备将使用第二音量播放该音频数据。如图18所示，用户设置电脑的音量为50％，电脑上显示音量进度条181，音量进度条181上显示当前音量为50％。在手机将音频数据传输至电脑上后，电脑以50％音量播放音频数据。
在一些实施例中，第一电子设备提供给用户的音量控制能力中包括“安全模式”。在“安全模式”下，用户输入的操作可以使得第一电子设备不断地设置第二音量并不断向第二电子设备传输该第二音量，直至传输的第二音量满足第一预设条件。第一电子设备可以响应于用户输入的操作，向第二电子设备传输第三音量，第三音量小于第二音量；持续增加第三音量，并将调整后的第三音量传输给第二电子设备，直至调整后的第三音量达到第二音量或达到第一预设条件，其中第一预设条件为第一电子设备采集到的第二电子设备播放音频的音量满足第一电子设备所认定的达到第二音量的实际音量。例如直至第一电子设备检测到第二电子设备所播放音频的音量(如分贝)合适即达到第一预设条件，或直至第二电子设备对其音量进行调整后得到的音量达到第二音量(如百分比)。
也即，在“安全模式”下，可以通过一个步骤来设置第二音量以及触发第一电子设备将第二音量和音频数据传输给第二电子设备。第一操作和第二操作可以合并为一个操作，或者 说第一操作具有第二操作的功能，第二操作为可选操作。
示例地，请参阅图19(a)，用户输入的操作可以包括用户按压开关键191与电脑图标503，以此触发安全模式。手机检测到用户触发安全模式，如图19(b)，手机建立与第二电子设备的连接，并向电脑传输第三音量10％和音频数据。华为电脑接收到第三音量为10％，将其音量设置为10％。华为电脑以10％音量播放音频数据。手机检测到华为电脑播放音频的分贝为5dB，未达到预设分贝10dB。如图19(c)，手机根据步进值10％调整第三音量，手机将第三音量10％增加步进值10％，得到20％音量，手机继续向电脑传输第二音量20％和音频数据。华为电脑接收到第二音量为20％，将其音量设置为20％。华为电脑以20％音量播放音频数据，手机检测到华为电脑播放音频数据的分贝为10dB，达到预设分贝10dB，则手机停止继续向电脑传输第二音量。
在一些实施例中，在安全模式下，第一电子设备向第二电子设备传输安全模式指令与第三音量。第二电子设备接收到该安全模式指令，响应于该安全模式指令不断调整该第三音量，直至第一电子设备检测到当前第二电子设备所播放音频的音量合适，或直至第二电子设备调整后的第三音量达到第二音量。在第一电子设备检测到第二电子设备所设置的音量达到第一预设条件，则第一电子设备向第二电子设备发送停止指令，第二电子设备停止设置其音量，并以该达到预设条件的音量播放音频。
在本申请实施例中，通过显示待接收音频数据的电子设备当前音量，并提供对待接收音频数据的电子设备音量控制能力，便于用户在将音频数据传输至该待接收音频数据的电子设备后，该待接收音频数据的电子设备可以以合适的音量播放音频数据，避免声音流转带来的刺耳干扰的情况，给音频分享带来全新体验。
