随着智能家居技术的发展和人们对高品质居家生活的追求，全屋音响给人们的居家生活带来震撼的听觉享受。多台智能音箱通过WiFi互相连接，并同步播放音乐，让用户在走动的过程中，也能有沉浸式的听音体验。终端音箱从服务器上拿到音频数据，并通过无线网络传送给所有房间内的音箱。通过一定的同步机制来保证相同的音频帧在相同的时间内播放出来。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
在附图中，自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。所描述的实施例是本公开一部分实施例，而不是全部的实施例。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。下面结合附图对本公开的实施例进行详细说明。
本公开实施例提供的音箱播放控制方法，可以应用于通过无线通信技术相连的多个智能设备，实现用户与用户之间共享音乐的应用场景。尤其是，设定空间内的多个智能设备，其中多个智能设备分别属于不同的子空间，且多个智能设备中包括主控智能设备以及子智能设备。其中，智能设备可以是智能音箱，也可以是其他智能设备。
智能音箱的普及和用户日益提升的听音需求，使得各大公司都致力于提升各自音箱的音乐播放功能，这其中一个突破性的进展是音箱之间通过无线网络互联，实现全屋播放功能。多台智能音箱通过WiFi互相连接，并同步播放音乐，让用户在走动的过程中，也能有沉浸式的听音体验。音箱从服务器上拿到音乐数据，并通过无线网络传送给所有房间内的音箱。通过一定的同步机制来保证相同的音频帧在相同的时间内播放出来，从而实现家庭内所有的智能音箱一起同步播放音乐。
相关技术中，通过WiFi互联互通，实现多个智能音箱之间的信息交互。主控音箱从 服务器上拿到音频数据，将音频数据等时间长度分帧，并给每个音频帧标记对应的时间信息，通过WiFi打包发送给所有房间的其他子音箱。其他子音箱通过WiFi接收到主控音箱发送来的音频帧包并解析出音频数据和时间信息。在音频帧包交互的同时，其他子音箱要同主控音箱做系统时钟的交互，以此达到主控音箱和其他子音箱系统时钟上的对齐，从而保证主控音箱和其他子音箱的数据处理是在同一个时钟基准上。在主控音箱和其他子音箱系统时钟同步的基础上，分别开始对音频数据进行处理。主控音箱和其他子音箱设定固定时间后，将同样的音频帧播放出来，从而实现了多个音箱的音频同步播放，达到全屋播放的听音体验。但是，在家庭中，通常用户只会在其中的一个或部分房间，在没人的房间播放音乐，一个会浪费电能，另一个由于发送数据占用网络通道，网络资源占用越多，越可能导致整个系统不稳定，例如，多个音箱之间无法同步的进行播放音频数据。
有鉴于此，本公开提供了一种音箱播放控制方法，在确定音箱启用音频播放功能时，通过主控音箱从服务端获取音频数据，并在多个子音箱所属的子空间中确定目标子空间，其中，目标子空间为用户当前所在的子空间，子空间为一个完整空间被划分为多个空间中的一个空间。进一步的，由主控音箱将从服务端获取的音频数据发送至用户当前所在空间内的子音箱，并由子音箱基于音频数据进行音频播放。基于此，空间内的音箱选择性的根据用户当前所处空间进行播放音频数据，从而减少了能源的浪费，即在当前空间内，没有检测到用户存在在此空间的音箱就处于不工作状态。同时，将主控音箱与不进行播放音频数据的子音箱之间的信道资源进行释放，尽可能的减少网络负载，可以提升系统的稳定性，且为用户提供了更加稳定的听觉体验。因此，相较于相关技术中控制音箱播放的方式，本公开提供的音箱播放控制方法体现的更加灵活及智能。
图1是根据一示例性实施例示出的一种音箱播放控制方法的流程图，如图1所示，应用于主控音箱，包括以下步骤。
在下述公开实施例中，将既与服务端通信又与其他音箱通信的音箱称为主控音箱，将与主控音箱通信的音箱称为子音箱，其中，主控音箱用于控制多个子音箱，同一空间的不同子空间中包括有不同的子音箱。同一子空间中可以包括一个或多个不同的子音箱。
在步骤S11中，在确定主控音箱启用音频播放功能，从服务端获取音频数据，并在多个子音箱所属的子空间中确定目标子空间。
其中，目标子空间为用户当前所在的子空间。其中，子空间可以理解为任意一个房间，比如：客厅、厨房、卧室等。
在本公开实施例中，在确定用户已将房间内所有音箱的音频播放功能启动时，主控音箱通过无线传输技术，从服务端获取音频数据。并通过接收子空间内的子音箱发送的信号， 确定用户当前所在的房间。
在步骤S12中，将音频数据发送至目标子空间内的子音箱，控制目标子空间内的子音箱基于音频数据进行音频播放。
在本公开实施例中，当主控音箱确定哪一个空间内存在用户的情况下，将从服务端获取得到的音频数据发送至存在用户的空间内的子音箱，并控制该空间内的子音箱播放解码后的音频数据。
在本公开中，主控音箱通过子空间内的子音箱发送的指令确定非目标子空间，其中，非目标子空间为不存在用户的各设定子音箱所属的子空间。在主控音箱确定非目标子空间的情况下，停止向非目标子空间内的子音箱发送音频数据。
在本公开实施例中，在主控音箱确定该子空间内不存在用户，则主控音箱停止向该空间内的子音箱发送音频数据，关闭主控音箱与该空间内子音箱之间的信道。将主控音箱与不进行播放音频数据的子音箱之间的信道资源进行释放，提高了系统的稳定性，为用户提供了更加稳定的听觉体验。
在本公开中，在确定所有音箱启用音频播放功能，从服务端获取音频数据，并在多个子音箱所属的子空间中确定目标子空间。将音频数据发送至目标子空间内的子音箱，控制目标子空间内的子音箱基于音频数据进行音频播放。通过本公开，空间内的音箱选择性的根据用户当前所处空间进行播放音频数据，从而减少了能源的浪费。可以理解为，只有该空间内存在用户时，主控音箱才向该空间内的子音箱发送音频数据。
基于上述实施例，可知主控音箱确定目标子空间是关键的一个步骤，因此，在下述公开实施例中，将对主控音箱如何确定目标子空间进行具体说明。
图2是根据一示例性实施例示出的一种确定目标子空间的流程图，如图2所示，在多个子音箱所属的子空间中确定目标子空间，包括以下步骤。
在步骤S21中，确定用户检测结果。
其中，用户检测结果由子空间中设定子音箱基于用户人体活动探测确定，且用户检测结果包括存在用户或不存在用户。
在步骤S22中，将检测结果为存在有用户的目标子音箱所属的子空间，确定为目标子空间。
在本公开实施例中，若子空间中设定的子音箱探测到空间内存在用户人体活动，则主控音箱接收到来自子音箱的确认用户存在的指令，并将存在有用户的目标子音箱所属的子空间，确定为目标子空间。若子空间中设定的子音箱没有探测到空间内存在用户人体活动，则主控音箱接收到来自子音箱的确认用户不存在的指令。
在本公开中，确定用户检测结果。将检测结果为存在有用户的目标子音箱所属的子空间，确定为目标子空间。通过本公开，基于子音箱向主控音箱传输的检测结果指令，主控音箱发送相对应的指令控制子音箱，实现了子音箱与主控音箱之间的交互。
图3是根据一示例性实施例示出的一种控制目标子空间内的子音箱基于音频数据进行音频播放的流程图，如图3所示，将音频数据发送至目标子空间内的子音箱，控制目标子空间内的子音箱基于音频数据进行音频播放，包括以下步骤。
在步骤S31中，确定目标子空间对应的目标空间标识。
其中，多个子音箱对应有空间标识，空间标识用于标识子音箱所属的子空间。
在本公开实施例中，将房间环境划分为多个子空间，比如：厨房、客厅、卧室等子空间。首次配网时通过用户选择音箱所处空间，例如，用户可以通过音箱显示屏上的可伸缩列表对音箱当前所处空间进行选择，这样每一个音箱就知道当前所处的空间环境。例如，音箱A和音箱B当前在客厅放置；音箱C和音箱D当前在主卧室放置等等。其次，目标子空间内的子音箱通过超声波通信方式相互感知，确定各子音箱所属的子空间。子音箱将自己的空间标识发送至主控音箱，主控音箱将子空间内的所有子音箱的IP地址或者其他识别ID存储在设备的列表之中，从而可以确定目标子空间对应的目标空间标识。
在步骤S32中，将音频数据发送至目标空间标识所标识的目标子空间内的子音箱，并基于目标空间标识控制目标子空间内的子音箱基于音频数据进行音频播放。
在一示例中，用户可以提前选定目标子空间内的其中一个子音箱，通过该子音箱探测空间内是否有用户活动，且将检测结果发送至主控音箱。也可以通过目标子空间内的子音箱相互感知，将性能最优的音箱设定为探测空间内是否有用户活动，且将检测结果发送至主控音箱的设定音箱。假设用户当前在主卧室活动，主卧室内设定的子音箱探测到有人体活动，则该音响发送确认指令至主控音箱，主控音箱将音频数据发送至主卧室内的子音箱，并控制主卧室内的子音箱进行音频播放。
在本公开中，确定目标子空间对应的目标空间标识。将音频数据发送至目标空间标识所标识的目标子空间内的子音箱，并基于目标空间标识控制目标子空间内的子音箱基于音频数据进行音频播放。通过本公开，主控音箱可以精确的控制用户存在的空间内的子音箱进行音频播放。
图4是根据一示例性实施例示出的一种控制目标子空间内的子音箱基于音频数据进行音频播放的流程图，如图4所示，基于目标空间标识控制目标子空间内的子音箱基于音频数据进行音频播放，包括以下步骤。
在步骤S41中，向第一目标子空间中的子音箱发送第一控制播放指令，基于第一控制 播放指令控制第一目标子空间内的子音箱基于第一控制播放指令和音频数据进行音频播放。
其中，第一控制播放指令用于控制子音箱播放声音由大变小。
在本公开实施例中，当用户离开客厅(即第一目标子空间)时，此时客厅内的子音箱探测不到用户人体活动，子音箱将确认用户不存在指令发送给主控音箱。主控音箱接收到该指令后，向客厅内的子音箱发送音量减弱控制指令(即第一控制播放指令)，控制子音箱播放声音由大变小直至没有。
在步骤S42中，向第二目标子空间中的子音箱发送第二控制播放指令，基于第二控制播放指令控制第二目标子空间内的子音箱基于第二控制播放指令和音频数据进行音频播放。
其中，第二控制播放指令用于控制子音箱播放声音由小变大。
在本公开实施例中，当用户走入卧室(即第二目标子空间)时，此时卧室内的子音箱探测到了用户人体活动，子音箱将确认用户存在指令发送给主控音箱。主控音箱接收到该指令后，向卧室内的子音箱发送音量增强控制指令(即第二控制播放指令)，控制子音箱播放声音由小变大。
在本公开中，向第一目标子空间中的子音箱发送第一控制播放指令，基于第一控制播放指令控制第一目标子空间内的子音箱基于第一控制播放指令和音频数据进行音频播放。向第二目标子空间中的子音箱发送第二控制播放指令，基于第二控制播放指令控制第二目标子空间内的子音箱基于第二控制播放指令和音频数据进行音频播放。通过本公开，主控音箱还可以根据子空间内的子音箱的检测结果，控制子音箱播放音频音量的变化，使得子音箱在音量上可以实现渐变的效果，为用户带来良好的听觉体验。
本公开实施例提供一种音箱播放控制方法，应用于主控音箱，主控音箱与服务端进行通信，接收来自服务端的音频数据。将接收到的音频数据进行解码，得到解码后的音频数据。再根据预设的时长进行划分，得到音频帧数据。根据接收到的各个子空间内的子音箱的指令，进行进一步的操作。若接收到子音箱告知有用户存在的指令，则继续向该空间内的子音箱发送音频数据和播放控制指令，在传输音频数据的同时也需要传输时钟数据进行校对；若接收到子音箱告知没有用户存在的指令，则停止向该空间内的子音箱发送音频数据。通过本公开实施例，空间内的音箱选择性的根据用户当前所处空间进行播放音频数据，从而减少了能源的浪费。同时，将主控音箱与不进行播放音频数据的子音箱之间的信道资源进行释放，提高系统的稳定性。
图5是根据一示例性实施例示出的一种音箱播放控制方法的流程图，如图5所示，应 用于子音箱，包括以下步骤。
在步骤S51中，目标子空间中的子音箱获取主控音箱发送的音频数据。
在步骤S52中，基于音频数据进行音频播放。
在本公开中，获取主控音箱发送的音频数据。基于音频数据进行音频播放。通过本公开，子音箱由主控音箱进行控制，实现了子音箱与主控音箱之间的交互。
图6是根据一示例性实施例示出的一种检测目标子音箱所属的子空间内是否存在用户的流程图，如图6所示，子音箱为设定子音箱，设定子音箱用于检测目标子音箱所属的子空间内是否存在用户，包括以下步骤。
在步骤S61中，进行人体活动探测，并基于人体活动探测结果确定用户检测结果。
其中，用户检测结果包括存在用户或不存在用户。
在本公开实施例中，在每个子空间内随机选取或依据子音箱性能选取一个子音箱发射并接收超声波。当所有音箱的播放音频功能开启后，每个子空间内选定的子音箱发射超声波进行用户人体活动探测。本公开实施例中，采用差分信道冲击响应(dCIR)对用户人体活动进行探测。该探测方法的本质就是通过实时计算环境中的dCIR。当用户当前不在子空间A内时，子空间A内的子音箱回采超声波的dCIR值趋近于0。此时，目标子空间内设定的子音箱就会向主控音箱发送空间内不存在用户的指令。主控音箱接收到该指令后，向子音箱发送相对应的指令操作。当用户当前在子空间B内时，子空间B内的子音箱回采超声波的dCIR值会反映在dCIR上的幅值变化。此时，目标子空间内设定的子音箱的dCIR幅值发生变化，则该音箱就会向主控音箱发送空间内存在用户的指令。主控音箱接收到该指令后，向子音箱发送相对应的指令操作。通过检测dCIR的整体幅值状态，即可探测当前子空间内是否有用户存在。
在本公开实施例中，dCIR的应用原理基于下述算式：
Figure PCTCN2022099595-appb-000001
上式中，s为扬声器发射的超声波信号，r为麦克风采集到的超声波信号，h为CIR向量。h的计算式为：h＝(S TS) -1SR。dCIR描述为：
Figure PCTCN2022099595-appb-000002
其中m为当前帧。dCIR的幅值统计为：
Figure PCTCN2022099595-appb-000003
当AMP dCIR大于设定的阈值时，则判定为当 前子空间有人，其中，设定的阈值经实验验证可以为3。
在步骤S62中，向主控音箱发送用户检测结果。
在本公开实施例中，当子空间内的子音箱判定用户当前正位于与子音箱所处同一房间时，向主控音箱发送指令，告知主控音箱可以继续向该子空间内的子音箱发送音频帧数据。在这种情况下，当主控音箱接收到来自子音箱的发送指令时，则可以确定出该子空间中设定子音箱确定的用户检测结果是有用户存在。主控音箱将检测结果为存在有用户的目标子音箱所属的子空间，确定为目标子空间。
在本公开实施例中，子空间内的子音箱也可以检测出当前子空间内没有用户存在。
在本公开中，向主控音箱发送非目标子空间信息，非目标子空间为检测结果为不存在用户的各设定子音箱所属的子空间。控制主控音箱停止向非目标子空间发送音频数据。
在本公开实施例中，当子空间内的子音箱回采得到的超声波的dCIR值趋近于0，则确定当前该子空间内不存在用户。当确定该子空间内不存在用户时，子音箱会向主控音箱发送指令，告知自己所属空间内不存在用户。
在本公开实施例中，当主控音箱接收到来自子音箱发送的非目标子空间信息，确定该子音箱所处的空间内没有用户存在。为了避免资源的浪费，主控音箱停止向非目标子空间发送音频数据。
在本公开中，进行人体活动探测，并基于人体活动探测结果确定用户检测结果。向主控音箱发送用户检测结果。通过本公开，对用户不存在的子空间内的子音箱及时停止发送音频数据，动态的释放信道资源，保证了系统的稳定性，提供了更加优质的听觉体验。
图7是根据一示例性实施例示出的一种获取主控音箱发送的音频数据的流程图，如图7所示，获取主控音箱发送的音频数据，包括以下步骤。
在步骤S71中，获取主控音箱基于所述空间标识发送的音频数据。
在步骤S72中，基于不同的空间标识进行音频播放。
在本公开中，响应于空间标识为第一目标空间标识，获取主控音箱发送的第一控制播放指令，第一目标空间标识所标识的第一目标子空间为用户活动前所在的子空间，第一控制播放指令用于控制子音箱播放声音由大变小。基于第一控制播放指令，按照播放声音由大变小的方式基于音频数据进行音频播放。
在本公开实施例中，当用户离开客厅(即第一目标子空间)时，此时客厅内的子音箱探测不到用户人体活动，子音箱将确认用户不存在指令发送给主控音箱。主控音箱接收到该指令后，向客厅内的子音箱发送音量减弱控制指令(即第一控制播放指令)，控制子音箱播放声音由大变小直至没有。
在本公开中，响应于空间标识为第二目标空间标识，获取主控音箱发送的第二控制播放指令，第二目标空间标识所标识的第二目标子空间为用户活动后所在的子空间，第二控制播放指令用于控制子音箱播放声音由小变大。基于第二控制播放指令，按照播放声音由小变大的方式基于音频数据进行音频播放。
在本公开实施例中，当用户走入卧室(即第二目标子空间)时，此时卧室内的子音箱探测到了用户人体活动，子音箱将确认用户存在指令发送给主控音箱。主控音箱接收到该指令后，向卧室内的子音箱发送音量增强控制指令(即第二控制播放指令)，控制子音箱播放声音由小变大。
在本公开中，获取主控音箱基于所述空间标识发送的音频数据。基于不同的空间标识进行音频播放。通过本公开，主控音箱还可以根据子空间内的子音箱的检测结果，控制子音箱播放音频音量的变化，使得子音箱在音量上可以实现渐变的效果，为用户带来良好的听觉体验。
图8是根据一示例性实施例示出的一种基于音频数据进行音频播放的流程图，如图8所示，基于音频数据进行音频播放，包括以下步骤。
在步骤S81中，校对子音箱和主控音箱之间的系统时钟。
在本公开实施例中，图9示出了一种校对主控音箱与子音箱之间的系统时钟的示意图。如图9所示，在主控音箱和子音箱发送音频数据的同时，主控音箱和子音箱还要进行时钟信息的交互。子音箱需要计算出自己与主控音箱之间的系统时钟差异，并将自己调整为与主控音箱一致的系统时钟。子音箱按照自己的时钟，在TB0时刻把时间信息通过WiFi发送给主控音箱，主控音箱根据自己的时钟，在TA0时刻接收到了子音箱的时间信息，然后主控音箱在TA1时刻把时间信息通过WiFi发送给子音箱，子音箱在TB1时刻收到主控音箱的时间信息。子音箱利用TB0、TA0、TA1、TB1这4个时间信息，则能计算出自己与主控音箱之间的系统时钟差异：T A0-T B0＝Δ+τ 0、T B1-T A1＝-Δ+τ 1其中Δ表示子音箱与主控音箱之间的系统时钟误差，τ 0和τ 1为主控音箱和子音箱之间的WiFi传输延迟。则系统时钟误差可以计算得到：
Figure PCTCN2022099595-appb-000004
子音箱将自己的系统时钟补偿上时钟差异Δ，则校准为与主控音箱一致的系统时钟。在所有音箱都与主控音箱时钟对齐的基础上，对于T0时刻的音频帧，都在T0+1s时刻播放出来，则实现所有音箱的同步播放。
在步骤S82中，基于校对后的系统时钟和音频数据，与主控音箱进行音频同步播放。
在本公开中，校对子音箱和主控音箱之间的系统时钟。基于校对后的系统时钟和音频 数据，与主控音箱进行音频同步播放。通过本公开，基于子音箱和主控音箱之间的系统时钟准则，实现各音箱同步音频播放，为用户带来良好的听觉体验。
图10示出了一种音响播放控制的示意图。如图10所示，首先对每个音箱所处的空间做一个划分，子空间的划分可以通过用户配置和自动感知两种形式来实现。其中，用户配合是指在用户每次给音箱配置网络时，选择该音箱所处的子空间，比如给音箱A和音箱B选择客厅，音箱C和音箱D选择主卧室，那么音箱A和音箱B互相知道它们在一个子空间内，音箱C和音箱D互相知道彼此在一个子空间内。自动感知则是不需要用户选择，音箱之间通过超声波通信来互相感知，如音箱A发送超声波信息只有音箱B能收到，而由于墙体阻隔音箱C和音箱D收不到，则音箱B知道音箱A和自己处于同一子空间。各个音箱依次感知，则最终能划分出全部音箱所处的子空间。将音箱A作为主控音箱，则所有设备所在空间的信息最后都汇总到A音箱，并把各个子空间内设备的IP地址或者其他识别ID存储在列表里。在此情况下，各个音箱之间建立了关联性的联系。在子空间1中，音箱M通过超声技术对用户进行检测，若音箱M检测到用户在子空间1内，则向主控音箱发送指令，告知子空间1内存在用户。在主控音箱收到来自音箱M的指令时，继续向子空间1内的音箱M、音箱N发送音频数据。若音箱M未检测到用户在子空间1内，则向主控音箱发送指令，告知子空间1内不存在用户。在主控音箱收到来自音箱M的指令时，停止向子空间1内的音箱M、音箱N发送音频数据，并关闭主控音箱与音箱M、影响N之间的信道。通过本公开，在没有用户存在的房间里停止该房间内音箱的播放功能，其一，节省了不必要的电能浪费；其二，节省了网络资源的占用，减少了网络负载，帮助提升了系统的稳定性。
本公开实施例提供一种音箱播放控制方法，应用于各个划分子空间内的子音箱，子音箱与主控音箱进行通信。当子音箱通过超声波技术检测到空间内存在用户时，向主控音箱发送有用户存在的指令；当子音箱通过超声波技术检测到空间内不存在用户时，向主控音箱发送没有用户存在的指令。在告知主控音箱空间内存在用户的情况下，接收来自主控音箱的音频数据和播放控制指令，对该数据进行解码并进行播放。
基于相同的构思，本公开实施例还提供一种音箱播放控制装置。
可以理解的是，本公开实施例提供的音箱播放控制装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约 束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
