Description

一种同时响应的方法及设备
本申请要求于2019年7月25日提交国家知识产权局、申请号为201910678890.4、申请名称为“一种同时响应的方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子技术领域，尤其涉及一种同时响应的方法及设备。
背景技术
多设备同时响应对音频同步、音视频同步或同步唤醒等场景具有重要意义。多设备同时响应可以提升用户的使用体验。
同时响应的多个设备之间可以采用主从关系。现有技术中，主设备和从设备可以分别从时钟源站点获取标准时间，从而进行网络时钟同步。而后，主设备可以向从设备发送指令，指示从设备在目标时间同时做出响应。主设备和从设备分别设置定时器，在定时器超时，即到达目标时间后，主设备和从设备分别做出响应。
其中，由于从时钟源站点到不同设备之间的网络传输存在不同程度的延迟，因而不同设备接收到标准时间的时刻不同，不同设备根据接收到的标准时间分别设置的时钟也不同，不同设备达到目标时间的实际时刻也不同。因此，多个设备之间无法同时进行响应，同时响应的一致性差，给用户的体验较差。
示例性的，该多个设备包括音箱1和音箱2。音箱1和音箱2被用户唤醒后，点亮灯环进行响应。由于现有技术中多个设备之间同时响应的一致性较差，因而如图1所示，音箱1和音箱2之间点亮灯环的过程难以同步，用户视觉体验较差。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
在一些场景中，多个设备之间同时响应具有严格的要求。例如，在立体声播放场景中，左、右声道的设备需要同时播放，以实现立体声同步播放。再例如，在音视频播放场景中，音频设备和视频设备需要同时播放，以实现声音和画面的同步和一致。
现有技术中，多个设备的同时响应通常基于网络时钟同步和定时器实现。网络时钟同步是指通过互联网传递统一的标准时间，该标准时间为绝对时间。例如，互联网中的时钟源站点通过网络将标准时间传递给多个设备。标准时间基于网络信道进行传递，而该传递过程需要传输时间，即存在网络传输时延。因而，标准时间到达各设备后，各设备上各自的时钟相对于标准时间会发生延迟。并且，由于时钟源站点与不同设备之间的网络信道的传输时间不同，因而各设备上各自的时钟相对于标准时间的延迟也存在误差。此外，由于时钟源站点为预先部署的若干时钟源站点中的一个，因而时钟源站点与多个设备之间的距离可能较远，从而使得标准时间的传输时间较长(比如可以为10s)，进而使得多个设备上各自的时钟相对于标准时间的延迟较大。
例如，如图2所示，时钟源站点通过网络将标准时间传输给设备A、设备B、设备C。从时钟源站点到设备A、设备B、设备C之间所消耗的传输时间，分别为传输时间a、传输时间b、传输时间c。由于不同设备对应的标准时间的传输时间不同，设备上的时钟基于标准时间设置，因而与标准时间相比，设备A、设备B、设备C上的时钟也不同。设备A、设备B、设备C上的时钟分别向后延迟了传输时间a、传输时间b、传输时间c。与标准时间相比，设备A、设备B、设备C上的时钟表示的当前时间分别与标准时间相差了传输时间a、传输时间b、传输时间c。举例来说，设备A上的时钟表示的时间为时刻1，实际标准时间为时刻1+a；设备B上的时钟表示的时间为时刻1，实际标准时间为时刻1+b；设备C上的时钟表示的时间为时刻1，实际标准时间为时刻1+c。
其中，设备A为主设备，设备B和设备C为从设备。主设备A向从设备B和从设备C发送响应指令，以指示在目标时间做出响应。主设备A、从设备B和从设备C，分别计算目标时间与当前时间的差值。设备A、从设备B和从设备C分别根据各自计算的差值设置定时器。其中，由于不同设备的工作频率可能不同、芯片的计算速度可 能也不同，从而导致不同设备之间的计算耗时也存在误差(例如为8ms)。并且，不同设备的定时器通过不同的物理时钟计数器实现。物理时钟计数器的工作频率不同，物理时钟计数器的计数精度也不同，因而不同定时器的定时时长也存在误差。
举例来说，时钟源站点在时刻1，将标准时间“时刻1”分别同步给主设备A、从设备B和从设备C。设备A在时刻1+a接收到时刻1；设备B在时刻1+b接收到时刻1；设备C在时刻1+c接收到时刻1。主设备A向从设备B和从设备C发送响应指令，指示在目标时间“时刻2”做出响应。时刻2与时刻1之间的差值为d。主设备A、从设备B和从设备C计算获得该差值d所花费的时长分别为f1、f2和f3。主设备A、从设备B和从设备C分别设置各自的定时器的时长为d。主设备A的定时器的定时误差为e1；从设备B的定时器的定时误差为e2；从设备C的定时器的定时误差为e3。那么，主设备A在时刻1+a+f1+d+e1后到达目标时间，从而进行响应；从设备B在时刻1+b+f2+d+e2后到达目标时间，从而进行响应；从设备C在时刻1+c+f3+d+e3后到达目标时间，从而进行响应。
也就是说，在现有同时响应方案中，由于存在网络传输时延、设备计算耗时误差和定时器定时误差等，因而主设备A、从设备B和从设备C并不能在时刻2同时做出响应，也不能同时做出响应。现有方案同时响应的误差较大，同时响应的一致性较差，用户体验较差。例如，在立体声播放场景中，由于同时响应的误差较大，因而左、右声道的设备难以实现同步播放，立体声播放效果较差。再例如，在音视频播放场景中，音频设备播放的声音与视频设备播放的画面和字幕等不同步，用户体验较差。
本申请实施例提供了一种同时响应的方法，可以应用于一组配合使用的电子设备。参见图3，该组电子设备包括通信网络中的设备A、设备B和设备C等。设备A、设备B和设备C等设备之间，通过一个或多个转发设备(或称中介设备)转发信息，从而进行相互通信。例如，设备A、设备B和设备C之间通过同一转发设备转发信息，从而进行相互通信。
再例如，设备A和设备B之间通过转发设备1转发信息从而进行相互通信；转发设备1与转发设备2可以通信，设备C通过转发设备2的转发与其他设备进行通信；设备C，与设备A和设备B之间通过转发设备1和转发设备2转发信息，从而进行相互通信。
示例性的，该通信网络可以是局域网(local area network，LAN)。该组电子设备包括同一局域网内的设备A、设备B和设备C。该局域网可以是有线局域网或无线局域网。其中，局域网是指在某一区域内由多台设备互联成的设备组。通常，局域网覆盖的地理范围较小，局域网内设备之间的通信延迟时间短等。例如，当该局域网为无线局域网时，具体可以是Wi-Fi局域网、Wi-Fi热点、蓝牙局域网或蓝牙热点等。在一些情况下，Wi-Fi局域网的概念也可以包括Wi-Fi热点，即Wi-Fi热点也属于Wi-Fi局域网。类似的，蓝牙局域网的概念也可以包括蓝牙热点，即蓝牙热点也属于蓝牙局域网。
其中，局域网内的设备通常需要通过一个或多个网关等转发设备(或称中介设备)转发信息，以使得局域网内的设备之间进行相互通信。当该局域网为Wi-Fi局域网时，该网关设备可以为无线路由器。一般情况下，同一网关管理的多个设备，可以属于同 一局域网。同一局域网也可以包括多个网关管理的多个设备。
可以理解的是，该通信网络也可以是局域网以外的其他通信网络。例如，该组电子设备也可以是广域网中的一组电子设备，本申请实施例对通信网络的类型不予限定。或者，该通信网络也可以是基于直连技术组成的无线网络。例如，该组电子设备之间可以是基于蓝牙直连、Wi-Fi直连、或Zigbee直连等近场直连技术组成的一组电子设备。
该组电子设备可以包括主设备和从设备。例如，如图3所示，该组电子设备包括主设备A，从设备B和从设备C。在本申请实施例提供的同时响应的方法中，主、从设备可以基于计算获得的相对时间进行同时响应，而不需要通过网络时钟同步获取标准时间(即绝对时间)，因而可以避免网络时钟同步的网络传输时延造成的误差，从而可以降低该组电子设备同时响应的时间误差，提高同时响应的一致性，提高用户体验。
在一些实施例中，主设备还可以计算多个定时器的定时时长并设置多个定时器，在定时器超时后通知相应的从设备进行响应，而不需要在不同设备上分别计算各自的定时器时长并分别设置定时器，因而还可以避免不同设备间的设备计算耗时误差和定时器的定时误差，从而可以降低该组电子设备同时响应的时间误差，提高同时响应的一致性，提高用户体验。
例如，在该组电子设备中，电子设备具体可以为音箱、灯泡、电视、机顶盒等智能家居设备，还可以是手机、耳机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)等设备。本申请实施例对电子设备的设备类型不作具体限定。
其中，该组电子设备中的多个电子设备，可以是同种类型的电子设备，也可以是不同类型的电子设备。例如，该组电子设备可以是音频设备、音视频设备、灯光设备或其他类型的设备等。
举例来说，该组电子设备为包括左声道音箱(即用于播放左声道音频的音箱)和右声道音箱(即用于播放右声道音频的音箱)，即包括一组同种设备类型的音频设备。左声道音箱和右声道音箱同时播放，从而实现立体声同步播放。
在另一个示例中，该组电子设备包括视频设备电视和音频设备音箱，即包括一组不同设备类型的电子设备。电视和音箱同时响应，分别播放视频和音频，从而实现画面和声音的同步播放。

以下通过不同应用场景的举例说明，来对本申请实施例提供的同时响应的方法进行阐述。
在一种应用场景中，该组电子设备为一组音频设备。该组音频设备可以接收用户的语音指令。例如，该组音频设备可以为一组音箱，一组耳机或一组其他音频设备。
示例性的，参见图5，该组音频设备包括客厅设置的音箱A，以及不同卧室内分别设置的音箱B和音箱C。音箱A、音箱B和音箱C可以通过无线路由器(或称无线接入点)接入同一Wi-Fi局域网。该无线路由器即为网关。需要注意的是，该无线路由器可以是一个也可以是多个(例如包括主路由器和从路由器)。
音箱A、音箱B和音箱C可以通过配对，组合为一组电子设备。该组电子设备的配对方式可以有多种。例如，在一些实施例中，该组电子设备是出厂时预先配对的一组电子设备。示例性的，该组电子设备为出厂时已配对的一组左声道音箱和右声道音箱。
再例如，在另一些实施例中，音箱A、音箱B、音箱C以及用户的手机，可以通过无线路由器接入同一Wi-Fi局域网。示例性的，参见图6中的(a)和图6中的(b)，用户可以通过手机APP对音箱A、音箱B和音箱C进行配对，从而将音箱A、音箱B和音箱C组合为一组电子设备。
其中，手机通过APP检测到用户指示将音箱A、音箱B和音箱C进行配对的指示操作后，可以通过云端服务器分别通知音箱A、音箱B和音箱C进行配对。音箱A可以将配对相关的信息，通过无线路由器发送给云端服务器，云端服务器再通过无线路由器转发给待配对的音箱B和音箱C。例如，配对相关的信息可以包括，IP地址，设备标识(比如序列号)，设备名称，设备型号，或配对响应信息等。同样，音箱C和音箱B也可以把配对的相关的信息，通过无线路由器和云端服务器转发给待配对的其他音箱。从而，音箱A、音箱B和音箱C之间可以交互配对相关的信息，完成配对过程。
其中，在该组电子设备中，主设备和从设备的角色可以是用户指定的。例如，用户可以通过APP指定音箱A为主设备，音箱B和音箱C为从设备。
或者，在该组电子设备中，主设备和从设备的角色也可以是手机自动确定的。例如，手机确定该组电子设备中，先接入Wi-Fi局域网的音箱为主设备，其他音箱为从设备。再例如，手机随机选择该组电子设备中的一个音箱作为主设备，其他音箱为从设备。再例如，该组电子设备中的不同音箱可以分别通过红外传感器、距离传感器等器件，确定与用户之间的距离，并将距离上报给手机，手机确定距离用户最近的音箱为主设备。再例如，该组电子设备中的不同音箱，可以分别检测用户的语音信号强度等参数，并将语音信号强度等参数上报给手机，手机根据语音信号强度等参数确定音箱与用户之间的距离，并确定距离用户最近的音箱为主设备。
在主设备和从设备的角色确定后，手机可以通过云端服务器和无线路由器将主、从设备的角色分别通知给音箱A、音箱B和音箱C；或者，主、从设备之间可以互相通知对方自身的角色。
在配对后，该组电子设备可以测量主设备与各从设备之间的传输耗时。其中，由于时钟源站点可能距离该组电子设备较远，因而与现有技术中时钟源站点与该组电子设备之间的传输时间相比，接入同一局域网的主设备与从设备之间的距离较近，因而主设备与从设备之间的传输耗时也更短。
在一些实施例中，从设备可以分别测量与主设备之间的传输耗时，并分别上报给主设备进行保存。该传输耗时为主设备和从设备之间传输信息需要消耗的时间。主设备可以确定与各从设备之间的传输耗时的最大值max(即最大传输耗时)。
在另一些实施例中，主设备可以分别测量与各从设备之间的传输耗时，并确定与各从设备之间的传输耗时的最大值max。
其中，主设备或从设备测量传输耗时的方法可以有多种。例如，音箱A测量与音箱B之间的传输耗时。音箱A可以向音箱B发送测量信息，并记录发送时刻。音箱B接收到音箱A发送的该测量信息后，可以记录接收时刻。音箱B向主设备发送响应信息，以将该接收时刻返回给音箱A。音箱A确定该接收时刻与该发送时刻之间的差值，即为音箱A与音箱B之间的传输耗时。再例如，在音箱A测量与音箱B之间的传输耗时时，音箱A可以向音箱B发送测量信息，并启动计时器。音箱B接收到音箱A发送的该测量信息后，即向音箱A回复响应信息。音箱A接收到该响应信息后停止计时器，并确定计时器计时时长的一半，即为音箱A与音箱B之间的传输耗时。
其中，音箱A分别与音箱B和音箱C之间的传输耗时可能相等，也可能不等。示例性的，音箱A与音箱B之间的传输耗时为ab(例如可以为12ms)，音箱A与音箱C之间的传输耗时为ac。若ac大于ab，则max＝ac。
这样，在配对时，该组电子设备之间可以交互配对相关信息；在配对后，该组电子设备之间还可以交互测量信息和响应信息等用于测量主、从设备之间传输耗时的其他信息。
此外，在该组电子设备发生断网的情况下，例如该组电子设备上/下电，该组电子设备的接入点发生更改，重置，上/下电，或者该组电子设备接入的局域网的名称或密码等发生更改等的情况下，传输耗时可能也发生了变化，因而在重新接入局域网后，该组电子设备还可以重新测量主设备与各从设备之间的传输耗时，并重新确定最大传输耗时max。
在一些实施例中，该组电子设备可以接收用户的语音指令，并针对用户的语音指令同时进行响应。例如，该组电子设备可以接收用户指示亮灯的指令，同时进行亮灯(即同时响应，或称同时执行响应操作)操作。再例如，该组电子设备可以接收用户的语音唤醒指令，并同时进行唤醒应答(即同时响应)。该唤醒应答可以包括亮灯(例如点亮灯环，点亮指示灯，不断闪烁指示灯)、声音(例如“嘀”一声，或发出声音“主人，我已被已唤醒”)或振动等多种方式。
以下以图5所示场景下，音箱A为主设备，音箱B和音箱C为从设备，该组电子设备在接收到用户的语音唤醒指示(即检测到响应指示)后，同时点亮灯环进行唤醒 应答为例进行说明。
在本申请的实施例中，主、从设备之间可以通过网关(例如无线路由器)的转发交互数据信息(例如数据指令)。或者，主、从设备之间还可以通过云端服务器和网关的转发交互数据信息。
通常，云端服务器的处理能力较强，能够更好地识别用户的语音信息，并根据用户的语音信息识别用户的意图，因而主、从设备之间还可以通过云端服务器的处理和网关的转发，处理语音信息。例如，从设备可以接收用户的语音信息，并通过网关上报给云端服务器。云端服务器对语音信息进行识别和处理后，获知用户意图，并将用户意图转化成相应的数据指令，通过网关将数据指令发送给主设备。或者，主、从设备之间可以通过网关的转发交互语音信息。
在一种情况下，语音唤醒指令为特定的语音指令，例如该语音唤醒指令可以为“小E小E！”。音箱A-C检测到该语音唤醒指令后确定用户想要唤醒音箱。例如，音箱A(即主设备)检测到用户的语音唤醒指令后，确定用户想要唤醒音箱。音箱A可以控制音箱A、音箱B和音箱C同时点亮灯环(即同时响应)。或者，音箱B或音箱C(即从设备)检测到该语音唤醒指令后，确定用户想要唤醒音箱，因而可以向音箱A发送相应的数据指令(即通过无线路由器向音箱A转发相应的数据指令)，以使得音箱A获知用户想要唤醒音箱。该种方法不通过云端服务器的转发指令信息，因而可以尽快唤醒音箱。
在另一种情况下，音箱B或音箱C检测到用户的语音唤醒指令后，可以通过云端服务器通知音箱A(即通过云端服务器的语音意图处理和无线路由器的转发通知音箱A)；音箱A可以控制音箱A、音箱B和音箱C开始同步点亮灯环。
在一些实施例中，参见图7，音箱A可以通过自身检测到用户的语音唤醒指令，或者根据从设备或云端服务器的通知获知用户的唤醒指示。若传输耗时ab和ac是音箱A测量获得的，且当前时刻为时刻1，则音箱A可以向音箱B发送响应指令1，该响应指令1包括传输耗时ab和最大传输耗时max。音箱A发送的ab和max，经过传输耗时ab后到达音箱B。即音箱B在时刻1+ab接收到音箱A发送的ab和max。音箱B接收到ab和max后，设置时长为max-ab的定时器，从而在经历max-ab时长之后进行响应。即音箱B在时刻1+ab+(max-ab)＝时刻1+max表示的时刻进行响应。
同理，音箱A可以向音箱C发送响应指令2，该响应指令2包括传输耗时ac和最大传输耗时max。音箱A发送的ac和max，经过传输耗时ac后到达音箱C。即音箱C在时刻1+ac接收到音箱A发送的ac和max。音箱C接收到ac和max后，设置时长为max-ac的定时器，从而在经历max-ac时长之后进行响应。即音箱C在时刻1+ac+(max-ac)＝时刻1+max表示的时刻进行响应。
需要说明的是，在上述图7，以及后续图9-图10B中，音箱A获知用户的唤醒指示后，即可以分别向音箱B和音箱C发送响应指令。也就是说，音箱A向音箱B发送响应指令，与音箱A向音箱C发送响应指令没有先后顺序。
还需要说明的是，在上述图7，以及后续的图9-图13中，音箱A、音箱B和音箱C之间的信息交互，例如响应指令，max，ab或ac等的交互，均是由一个音箱通过无线路由器转发给另一个音箱的；并不是音箱之间直接发送给对方的。
并且，音箱A在时刻1+max表示的时刻进行响应。
可见，音箱A、音箱B和音箱C均在时刻1+max表示的时刻同时进行响应。其中，若max＝ac，则音箱A、音箱B和音箱C均在时刻1+ac表示的时刻同时进行响应。若max＝ab，则音箱A、音箱B和音箱C均在时刻1+ab表示的时刻同时进行响应。
示例性的，若该唤醒应答为点亮灯环，则在时刻1+max表示的时刻，音箱A、音箱B和音箱C同时点亮灯环。如图8A所示，各音箱点亮灯环的过程可以同步。
再示例性的，若该唤醒应答为点亮一个或多个指示灯，则在时刻1+max表示的时刻，音箱A、音箱B和音箱C同时点亮该指示灯。如图8B，各音箱可以同步点亮该排指示灯。
再示例性的，若该唤醒应答为闪烁指示等，则在时刻1+max表示的时刻，音箱A、音箱B和音箱C同时开始以相同的频率闪烁指示等。
再示例性的，若该唤醒应答为“嘀”一声，则在时刻1+max表示的时刻，音箱A、音箱B和音箱C同时“嘀”一声。
再示例性的，若该唤醒应答为发出声音“主人，我已被已唤醒”，则在时刻1+max表示的时刻，音箱A、音箱B和音箱C同时发出声音“主人，我已被已唤醒”。
在图7所示的上述方案中，局域网内的主、从设备之间虽然存在传输耗ab和ac，但从设备侧在进行同时响应时考虑并抵消了该传输耗时，从而避免了传输耗时导致的同时响应的误差，提高了同时响应的一致性。
其中，由于主、从设备同时响应的一致性较高，因而音箱A、音箱B和音箱C可以同时进行唤醒应答，例如同时开始点亮灯环。并且，与图1所示的现有技术中的灯环点亮过程相比，音箱A、音箱B和音箱C之间点亮灯环的过程的同步性更好，用户视觉体验更好。
若传输耗时ab和ac分别是音箱B和音箱C测量并上报给音箱A的，当前时刻为时刻1，则参见图9，音箱A通过响应指令分别向音箱B和音箱C发送最大传输耗时max，而不再发送ab和ac。音箱A发送的max，经过传输耗时ab后到达音箱B。即音箱B在时刻1+ab接收到音箱A发送的max。音箱B接收到max后，设置时长为max-ab的定时器，从而在max-ab时长之后进行响应。即音箱B在时刻1+ab+(max-ab)＝时刻1+max表示的时刻进行响应。
同理，音箱A发送的max，经过传输耗时ac后到达音箱C。即音箱C在时刻1+ac接收到音箱A发送的max。音箱C接收到max后，设置时长为max-ac的定时器，从而在max-ac时长之后进行响应。即音箱C在时刻1+ac+(max-ac)＝时刻1+max表示的时刻进行响应。
并且，音箱A在时刻1+max表示的时刻进行响应。
在图7和图9所示的方案中，音箱A在当前时刻之后的max时长后进行响应，音箱B在接收到音箱A发送的max，并经历max-ab时长后进行响应，音箱C在接收到音箱A发送的max，并经历max-ac时长后进行响应。而max，max-ab和max-ac均为相对时间，也就是说，各音箱根据相对时间进行同步响应，并且考虑并抵消了局域网内主、从设备间的传输耗时；而且不需要通过网络时钟同步获取标准时间(即绝对时间)，因而可以避免网络时钟同步导致的延时，提高主、从设备同时响应的一致性， 提高用户体验。例如，采用图7所示的方案，可以使得不同音箱之间同时响应的时间误差降低至0.01ms以下。
以上主要描述的方案为，主设备在确定需要进行响应后(或者说在检测到响应指示后，例如在获知用户的唤醒指示后)，才向从设备发送响应指令，并将max、ab和ac发送给从设备，或者将max发送给从设备，从而进行同时响应。例如，上述图7所示方案的方法流程图可以参见图10A。
在其他一些技术方案中，参见图10B，主设备可以预先将max、ab和ac发送给从设备，或者预先将max发送给从设备。例如，在配对后，主设备预先将max、ab和ac分别发送给相应的从设备，或者预先将max发送给各从设备。而后，主设备在确定需要进行响应(例如获知用户的唤醒指示)后，再按照图7所示的时机向从设备发送响应指令，响应指令中可以不包括max-ab或max-ac，从而使得主设备和从设备进行同时响应。
由上描述可知，主、从设备之间的传输耗时ab和ac可以是音箱A测量的，也可以是音箱B和音箱C分别测量的；且主设备可以根据ab和ac确定max。在一些实施例中，在音箱A通过自身的检测或根据从设备或云端服务器的通知，获知用户的唤醒指示后，参见图11和图12，当前为时刻1，音箱A可以设置时长分别为max，max-ab，以及max-ac的定时器。在时长为max-ab的定时器超时后，即在时刻1+max-ab表示的时刻，音箱A向音箱B发送指令，以指示音箱B进行响应。该指令经过传输耗时ab到达音箱B。即，音箱B在时刻1+max-ab+ab＝时刻1+max表示的时刻接收到该指令。音箱B接收到该指令后，立即进行响应。即，音箱B在1+max表示的时刻进行响应。
可见，音箱A和音箱B之间虽然存在传输耗时ab，但音箱A端考虑并抵消了该传输耗时，从而避免了传输耗时导致的同时响应的误差。
在时长为max-ac的定时器超时后，即在时刻1+max-ac表示的时刻，音箱A向音箱B发送指令，以指示音箱B进行响应。该指令经过传输耗时ac到达音箱B。即，音箱B在时刻1+max-ac+ac＝时刻1+max表示的时刻接收到该指令。音箱B接收到该指令后，立即进行响应。即，音箱B在1+max表示的时刻进行响应。
可见，音箱A和音箱C之间虽然存在传输耗时ac，但音箱A端考虑并抵消了该传输耗时，从而避免了传输耗时导致的同时响应的误差。
在时长为max的定时器超时后，即在时刻1+max表示的时刻，音箱A进行响应。
也就是说，音箱A、音箱B和音箱C均在时刻1+max表示的时刻同时进行响应。
在图11和图12所示的方案中，音箱A在当前时刻之后的max时长后进行响应，在当前时刻之后的max-ab时长后指示音箱B进行响应，并在当前时刻之后的max-ac时长后指示音箱C进行响应。而max，max-ab和max-ac均为相对时间，也就是说，各音箱根据相对时间进行同步响应，并且考虑并抵消了局域网内主、从设备间的传输耗时；而且不需要通过网络时钟同步获取标准时间(即绝对时间)，因而可以避免网络时钟同步导致的延时，提高主、从设备同时响应的一致性，提高用户体验。
并且，与图7-图10B所示的方案相比，在图11和图12所示的方案中，主设备音箱A计算定时的时长并设置多个定时器。定时时长的计算设备均为同一设备，且多个定时器基于同一设备的物理时钟定时器实现。而不需要在不同设备上分别计算各自的 定时器时长并分别设置定时器，因而还可以避免不同设备间的设备计算耗时误差和定时器误差。从而，可以降低该组电子设备同时响应的误差，提高同时响应的一致性，提高用户体验。例如，采用图11和图12所示的方案，可以使得不同音箱之间同时响应的时间误差降低至0.001ms以下。
此外，需要说明的是，在图11和图12所示的方案中，与不同从设备(即音箱B和音箱C)分别测量与主设备(即音箱A)之间的传输耗时相比，由主设备测量与不同从设备之间的传输耗时，可以使得测量过程的执行主体均为同一主设备，可以避免不同电子设备分别测量传输耗时导致的测量误差，从而提高测量精度。
在其他一些实施例中，max可以替换为T＝max+T0，T0大于或者等于0，即T大于或者等于max。当T0为0时，主设备和从设备可以尽快在同一时刻同时进行响应，用户体验更好。
在其他一些实施例中，该组电子设备还可以接收语音唤醒指令以外的用户其他语音指令，并进行同时响应。例如，用户其他语音指令为用户设置明天早上8:00的闹钟的语音指令。
其中，由于语音唤醒指令以外的用户其他语音指令通常不是特定的指令，具有个性化和随意性。不同用户针对同一指示下发的语音指令通常不同。而云端服务器具有较强的语音意图处理能力。因而，主设备或从设备检测到的语音唤醒指令以外的用户其他语音指令，通常需要通过无线路由器上报给云端服务器，经过云端服务器的处理后转换成相应的数据指令，再通过无线路由器转发给主设备。主设备控制与从设备同时进行响应。
例如，主设备音箱A检测到用户设置明天早上8:00的闹钟的语音指令。音箱A、音箱B和音箱C可以采用图7-图12所示的同时响应的方法，在第二天早上8:00同时启动闹铃提醒。再例如，从设备音箱B检测到用户设置明天早上8:00的闹钟的语音指令。音箱B通过无线路由器和云端服务器将该闹钟设置通知给音箱A。音箱A、音箱B和音箱C可以采用图7-图12所示的同时响应的方法，在第二天早上8:00同时启动闹铃提醒。
再例如，该组电子设备接收用户用于指示播放、暂停、上一首/下一首、增大音量、减小音量等的语音控制指令。该组电子设备可以采用图7-图12所示的方法进行同时响应。
另外，用户还可以通过手机APP，以语音指令、按键操作或触摸操作等方式，指示该组电子设备进行播放、暂停、上一首/下一首、增大音量、减小音量等控制操作。APP通过云端服务器通知主设备。需要注意的是，云端服务器具体可以通过无线路由器将相关指令转发该主设备。主设备和从设备可以采用图7-图12所示的方法进行同时响应，从而同时启动播放，同时暂停，同时切换到上一首/下一首，同时增大音量，或同时减小音量等。
此外，从设备还可以检测用户的按键操作或触摸操作等指示，并通知主设备。需要注意的是，从设备具体可以通过无线路由器将相关指令转发给主设备。例如，从设备检测到用户通过按键操作指示播放下一首歌曲的指示后，通知主设备。主设备和从设备可以采用图7-图12所示的方法进行同时响应，从而同时切换到播放下一首歌曲。
需要说明的是，以上主要是以从设备包括2个设备为例进行说明的。在其他一些实施例中，从设备的数量还可以大于2个，上述max为各从设备与主设备之间的传输耗时的最大值。
在其他一些实施例中，从设备还可以是1个，max即为主设备与该从设备之间的传输耗时。示例性的，主设备为音箱A，从设备为音箱B，max为主设备测量的与从设备之间的传输耗时为ab。音箱A检测到响应指示后，响应于该响应指示，在经历T＝ab+T0时长后进行响应，T0大于或者等于0，即T大于或者等于ab。例如，音箱A检测到响应指示可以为，音箱A检测到用户的语音指令，按键操作或触摸操作等指示，或者接收到云端服务器或从设备发送的指令等。
当T0等于0时，参见图13，音箱A检测到响应指示，在经历ab时长后进行响应。并且，音箱A响应于检测到该响应指示，可以向音箱B发送响应指令。音箱B接收到该响应指示后，可以立即进行响应。
当T0大于0时，在一些情况下，音箱A检测到响应指示，在经历T时长后进行响应。并且，音箱A响应于检测到该响应指示，可以在经历T-ab(即T0)后向音箱B发送响应指令。音箱B接收到该响应指示，可以立即进行响应。在另一些情况下，音箱A检测到响应指示，在经历T时长后进行响应；并且，音箱A响应于检测到该响应指示，向音箱B发送响应指令。音箱B接收到该响应指示，在经历T-ab(即T0)后进行响应。
在另一种应用场景下，该组电子设备为一组音频设备。该组音频设备可以配合使用，以实现音频立体声播放。例如，该组音频设备可以包括左声道音箱和右声道音箱。再例如，该音频设备可以包括左声道耳机和右声道耳机。

在主设备检测到用户的语音指令，按键操作或触摸操作等指示后，或者接收到云端服务器或从设备发送的指令后，主、从设备可以采用图7-图13所示的方法进行同步响应。从而，可以实现立体声同步播放，或者同步暂停，同步增大音量，同步减小音量，同步切换下一首/上一首等播放控制。其中，由于各音频设备之间同时响应的一致性较高，因而立体声播放效果较好，不会让用户感觉到左、右声道的音频不同步，用户听觉体验较好。

再例如，参见图14，该组电子设备包括一台电视和两台音箱。电视用于播放视频画面，一台音箱用于播放左声道音频，另一台音箱用于播放右声道音频。该组电子设备包括1个主设备(例如电视)和2个从设备。主、从设备可以采用图7-图13所示的方法进行同步响应，以实现音视频的同步播放。其中，由于该组音视频设备同时响应的一致性较高，因而视频和音频之间的同步效果较好，且立体声播放效果较好，用户体验较好。
再例如，该组电子设备包括一台电视和一台音箱。电视自身带有音箱，电视用于播放视频画面和左声道音频，音箱用于播放右声道音频。该组电子设备包括1个主设备和1个从设备。主、从设备可以采用图7-图13所示的方法进行同步响应，以实现音频和视频的同步播放，以及立体声音频的同步播放。
在另一种应用场景下，该组电子设备为一组视频设备。该组视频设备可以配合使用的左眼图像播放设备以及右眼图像播放设备。在主设备检测到用户的语音指令，按键操作或触摸操作等指示后，或者接收到云端服务器或从设备发送的指令后，主、从设备可以采用图7-图13所示的方法进行同步响应，以实现左、右眼图像的同步播放，以及同步暂停，同步切换视频等播放控制。其中，由于该组视频设备同时响应的一致性较高，因而左、右眼图像的同步效果较好。
在另一种应用场景下，该组电子设备为一组音频和灯光配合的电子设备。该组电子设备可以包括配合使用的音频设备和发光设备。例如，该组电子设备包括一台音箱和至少一个灯泡。该灯泡可以根据音箱播放的声音的响度、音调、音色、音阶或频率等特征的变化，配合发出不同颜色的光线或者以不同的频率进行灯光闪烁，从而展示不同的灯光效果。该组电子设备中的主设备可以为音箱，从设备可以为该至少一个灯泡。在主设备检测到用户的语音指令，按键操作或触摸操作等指示后，或者接收到云端服务器或从设备发送的指令后，主、从设备可以采用图7-图13所示的方法进行同步响应，以实现音乐和灯光的交织和配合。其中，由于同时响应的一致性较高，因而声音和灯光之间的配合较好，用户体验较好。

例如，在一些实施例中，该组电子设备可以接入同一Wi-Fi热点。示例性的，参见图15，手机开放了一个Wi-Fi热点，该组电子设备接入了该Wi-Fi热点。例如，该组电子设备可以为接入该Wi-Fi热点的音箱A、音箱B和音箱C。在该场景中，手机的功能类似于上述无线路由器(即网关)的功能，可以在该组电子设备的主、从设备之间转发信息；还可以结合云端服务器，在该组电子设备的主、从设备之间转发信息。本申请实施例不予赘述。该组电子设备的主、从设备之间，可以基于Wi-Fi热点协议，通过手机的转发进行通信，并采用图7-图13所示的方法进行同时响应。
