Description

一种调节音量的方法、系统及电子设备
本申请要求于2021年03月31日提交国家知识产权局、申请号为202110353347.4、申请名称为“一种调节音量的方法、系统及电子设备”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
本申请涉及智能家居技术领域，尤其涉及一种调节音量的方法、系统及电子设备。
背景技术
智慧屏设备也称为智屏，区别于传统电视产品，智慧屏设备将承担家庭中的更多角色，不仅是家庭的影音娱乐中心，更是信息共享中心、控制管理中心和多设备交互中心。
目前智慧屏设备在播放视频/音频时，用户可以通过智慧屏设备的遥控器上的按键或者通过与智慧屏设备连接的移动终端的触控屏的触控件来调节智慧屏设备的播放音量。例如，当用户距离智慧屏设备较远的时候，为了需要能够听清楚，用户可以手动调节触控件以将智慧屏设备的音量调大。而当用户距离智慧屏设备较近的时候，为了避免损害听力，用户可以手动将调节触控件以将智慧屏设备的音量调小。此外，可以通过设置在智慧屏设备上的距离传感器来检测用户与智慧屏设备之间的距离。然后，智慧屏设备基于用户于智慧屏设备之间的距离自动调整智慧屏设备的播放音量的方式实现音量的自动调节。然而这种方式没有考虑到环境噪声对播放音量的影响，这样会因为环境噪声太大，导致用户还是无法听清智慧屏设备播放视频/音频的声音。

智慧屏设备是传统电视的升级，智慧屏设备除了可以实现传统电视的音频/视频播放功能外，还可以实现设备交互及控制、信息共享等多个功能。
在使用智慧屏设备观看电视节目，跟随智慧屏设备播放的视频中的人物进行运动健身等各个生活场景，用户会根据自身需要对播放音量进行调节。比如，用户可以通过智慧屏设备的遥控器上的音量按键来调节播放音量。当前，智慧屏设备能够实现设备交互， 因此，智慧屏设备可以与用户的移动终端进行连接，然后用户可以通过移动终端触控屏中的触摸控件来实现音量调节。
除了通过用户来调节播放音量这种方式外，现有技术还提供了通过智慧屏设备或者通过与智慧屏设备连接的移动终端自动检测用户与智慧屏设备之间的距离，然后基于用户于智慧屏设备之间的距离自动调整播放音量的方案来实现音量调节。这种方式通常需要增加额外的传感器来检测用户与智慧屏设备之间的距离。而且在做音量调节的过程中忽略了环境噪声对播放音量的影响，这样有可能会导致调整后的音量也没办法满足用户的需求(因为环境噪声太大，用户还是无法听清智慧屏设备播放视频/音频的声音)。
此外，智慧屏设备还能够采集外界的声音(即智慧屏设备侧的环境噪声)，然后由智慧屏设备基于内部播放声音的大小和外界的声音大小来调节智慧屏设备的播放声音大小。然而，实际生活中智慧屏和用户的距离可能较远，用户周围的环境噪声较大的情况下，用户依旧没办法听清。
为了解决上述调节音量的方法调节后的音量不佳的问题，本申请实施例提供了一种调节音量的方法及系统、电子设备，通过可穿戴设备来采集用户侧噪声，融入用户侧噪声来实现音量调节，使得音量调节方案更具鲁棒性，使得用户能够清晰地听到智慧屏设备播放的声音。
需要说明的是，本申请实施例不仅适用于智慧屏设备的播放音量调节的场景，还适用于音箱、收音机、扬声器等媒体播放设备的播放音量调节场景。以下说明仅为示例而非限制。

下述以媒体播放设备100为智慧屏设备，可穿戴设备200为智能手环为例，对本申请实施例提供的一种音量的调节方法进行描述。
图3为本申请实施例提供的一种调节音量的方法的流程示意图，该方法包括：
S301、智慧屏设备与智能手环建立通信连接。
关于智慧屏设备与智能手环建立通信连接的方式可以参考上述实施例中的描述，此处不再赘述。
值得说明的是，在智能手环和智慧屏设备已经具有通信连接的情况下，上述建立通信连接便可以省略。
S302、在满足预设条件的情况下，智慧屏设备向智能手环发送该智慧屏设备播放内容时的目标音量，相应的，智能手环接收来自智慧屏设备播放内容时的目标音量。
例如，预设条件可以包括达到发送周期，换言之，智慧屏设备可以按照预设周期(5秒钟或者10分钟)周期性地向智能手环发送该智慧屏设备播放内容时的目标音量。
又例如，预设条件可以包括智慧屏设备播放内容时的音量发生变化。比如，当前时刻智慧屏设备播放内容时的目标音量为V1，而下一个时刻智慧屏设备播放内容时的目标音量为V2，则智慧屏设备可以向智能手环发送该智慧屏设备播放内容时的目标音量(即V2)。当智慧屏设备播放内容时的目标音量发生变化时，智慧屏设备再向智能手环发送该智慧屏设备播放内容时的目标音量与上述周期性发送目标音量相比可以降低信令开销。
再例如，预设条件可以包括智慧屏设备检测到智慧屏设备的开机指令。
在本申请的一个实施例中，在智能手环和智慧屏设备具有通信连接的情况下，智能手环也可以向智慧屏设备发送请求指令，该请求指令用于请求智慧屏设备向智能手环发送该智慧屏设备当前所播放的内容的目标音量。相应的，智慧屏设备在接收到请求指令之后便可以响应于该请求指令向智能手环发送智慧屏设备当前所播放的内容的目标音量。也即上述预设条件也可以包括基于智能手环的触发。
举例说明，如图1所示，小明坐在沙发上观看上述智慧屏设备上播放的视频，小明佩戴有上述智能手环，如果小明发现当前智慧屏设备上播放的视频音量很低，则小明可以点击智能手环上显示的请求控件。智能手环检测到请求控件被触发，则智能手环向智慧屏设备发送请求指令。
通过智慧屏设备和智能手环联动以调节智慧屏设备的音量是为了提高用户体验，但是在实际过程中，即使智慧屏设备和智能手环之间具有通信连接，也并不代表用户希望借助智能手环调节智慧屏设备的音量。基于此，本申请实施例中智慧屏设备可以具有一个控件，当该控件处于开启状态时，表示智慧屏设备授权和智能手环联动以调节智慧屏设备的音量。当该控件处于关闭状态时，表示智慧屏设备禁止和智能手环联动以调节智慧屏设备的音量。基于此，本申请实施例中在智慧屏设备控件处于开启的情况下，智慧屏设备便会在满足上述预设条件时向智能手环发送该智慧屏设备播放内容时的目标音量。
当然，智慧屏设备也可以默认授权和智能手环联动以调节智慧屏设备的音量。
S303、智能手环采集音频信号，该音频信号包括智能手环采集到的所述媒体播放设备在播放所述内容时的声音信号和智能手环采集到的噪声信号。
本申请实施例中的智能手环具有音频采集功能，这样智能手环便可以采集到周边一定范围内的各种音频信号。
例如，结合图1所示，用户坐在客厅的沙发上，这时客厅的智慧屏设备正在以目标音量播放视频“流浪地球”。智慧屏设备播放视频“流浪地球”时的声音经过空气传播至用户，由于声音传播过程中音量会被削弱，用户与智慧屏设备之间的距离越大，音量就会被削弱得更多，或者当用户与智慧屏设备之间具有阻碍物(比如墙壁)那么抵达用户侧的声音同样会被削弱。这样对于用户佩戴的智能手环而言，具有音频采集功能的智能手环就能够采集到用户周边的声音，对于智能手环而言其采集到的音频信号不仅包括智慧屏设备播放视频“流浪地球”时的声音经过空气传播至用户侧的声音，还包括部分噪声，比如环境噪声(窗外的汽笛声、室内外其他的讲话声)、室内外其他设备发出的声音等等。
在本申请的一个实施例中，为了节约智能手环的电量，智能手环上可以具有一个控制部件，当该控制部件被开启的情况下，智能手环便可以确定启动音频采集功能，以采集音频信号。当该控制部件未被开启的情况下，智能手表则关闭音频采集功能。此外，当该控制部件被开启的情况下，智能手环也可以向智慧屏设备发送请求指令。
S304、智能手环在采集到上述音频信号之后，对音频信号进行分离，以分离出智能手环采集到的噪声信号和智能手环采集到的所述媒体播放设备在播放所述内容时的声音信号。
例如，智能手环可以采用盲源分离算法对音频信号进行分离。盲源分离算法是目前常用的信号分离算法，本申请实施例可以使用现有的盲源分离算法(例如独立成分分析方法)从音频信号中分离出智能手环采集到的噪声信号和智能手环采集到的所述媒体播放设备在播放所述内容时的声音信号。
S305、智能手环根据智能手环采集到的噪声信号确定用户侧噪声强度，根据采集到的所述媒体播放设备在播放所述内容时的声音信号确定接收音量。
S306、智能手环根据目标音量、用户侧噪声强度以及接收音量确定调节音量。
智能手环可以根据接收音量和目标音量确定音量被削弱的程度，再根据音量被削弱的程度确定出一个调节基数。即当音量被削弱的程度小于预设削弱阈值时，智能手环将调节基数确定为0；当音量被削弱的程度大于或等于预设削弱阈值时，智能手环将调节基数确定为接收音量与目标音量的差值的绝对值。
智能手环可以根据用户侧噪声强度确定一个增强值。智能手环在确定出调节基数和增强值后，根据调节基数和增强值就能够确定出调节音量。
在本申请的一个实施例中，上述S306可以通过以下方式实现：智能手环可以将接收音量与目标音量进行比较，确定出调节基数。智能手环结合调节基数和用户侧噪声强度确定调节音量。
需要说明的是，智慧屏设备播放内容时的声音经过空气传播至用户，由于声音传播过程中音量会被削弱，因此达到用户侧时的音量(即接收音量)会小于目标音量。用户与智慧屏设备之间的距离越大，音量就会被削弱得更多。智能手环在确定了接收音量后，可以基于接收音量与目标音量的差值来确定出音量被削弱的情况。如果音量被削弱的程度小于预设削弱阈值，则说明用户与智慧屏设备之间的距离较小，因此智能手环可以只根据用户侧的环境噪音来确定调节音量，只有当环境噪音的音量大小超过预设噪音阈值 时，才提高智慧屏设备的播放音量(因为用户与智慧屏设备之间的距离比较小，因此需不需要提高音量只需要考虑环境噪音的影响)。在音量被削弱的程度大于或等于预设削弱阈值的情况下，可以提高智慧屏设备的播放音量(具体调节多少音量可以根据接收音量、目标音量以及用户侧噪声的大小来确定)，以使得用户可以听清楚智慧屏设备的播放音量。其中，预设削弱阈值可以根据实际场景来确定，本申请对此不加以限制。预设噪声阈值也可以根据实际情况来确定，本申请对此也不加以限制。
在此，当音量被削弱的程度小于预设削弱阈值时，可以将调节基数确定为0。当音量被削弱的程度大于或等于预设削弱阈值时，将调节基数确定为接收音量与目标音量的差值的绝对值。
具体地，智能手环还可以根据用户侧噪声强度确定出对应的噪声强度等级，再根据噪声强度等级确定出与该等级对应的增强值，最后再根据增强值和调节基础确定出调节音量。
示例性的，假设接收音量为A，目标音量为B，智能手环可以根据接收音量A和目标音量B确定出音量被削弱的程度S。
在本申请一实施例中，音量被削弱的程度S可以表示为：S＝(B-A)/B*100％。
当音量被削弱的程度S大于或等于预设削弱阈值时，智能手环可以将调节基数C确定为目标音量B和接收音量A的差值的绝对值，即C＝|B-A|。
智能手环根据用户侧的噪声信号确定出对应的噪声强度等级后，智能手环可以根据噪声强度等级确定出增强值D。
智能手环通过在调整基数C的基础上增加增强值D，就能够确定出调节音量F，即F＝C+D。
可以理解的是，当音量被削弱的程度S小于预设削弱阈值时，智能手环可以将调节基数C确定为0分贝。
可以理解的是，由于用户侧的噪声信号始终是存在的，因此增强值D不可能为负数，当用户侧噪声信号的噪声值小于预设噪声阈值时，对应的增强值可以是0分贝。在调节基数为0分贝，增强值为0分贝的情况下，调节音量也为0分贝。此时智能手环可以不向智慧屏设备发送音量调节指令。
在本申请实施例中，可以预先设置增强值与噪声强度等级的关联表，通过查表的方式就能够确定出于噪声强度等级对应的增强值。具体地，将用户侧噪声强度划分为若干个强度等级，然后每个强度等级分别对应一个增强值。示例性的，将用户侧噪声强度划分为N1、N2、N3、N4四个强度等级，N1强度等级对应的增强值为D1、N2强度等级对应的增强值为D2、N3强度等级对应的增强值为D3、N4强度等级对应的增强值为D4。需要说明的是，用户侧噪声强度的等级划分标准可以根据实际场景来确定，每个强度等级对应的增强值的具体数值可以根据现实情况来确定，本申请对此均不加以限制。
需要说明的是，智能手环还可以直接根据用户侧噪声强度的数值确定出与该数值对应的增强值。例如通过训练好的神经网络模型来实现，即将用户侧噪声强度输入到该训练好的神经网络模型中进行处理后，输出对应的增强值。还需要说明的是，上述神经网络模型可以使用现有的卷积神经网络模块来实现，本申请不对此加以限制。可以使用现有的神经网络模型来进行训练，对于神经网络的构建和训练过程本申请不再加以赘述。
S307、智能手环向智慧屏设备发送音量调节指令，相应的，智慧屏设备接收来自智 能手环的音量调节指令。
其中，音量调节指令包括调节音量，音量调节指令用于触发智慧屏设备调节智慧屏设备的音量。
在本申请实施例中，智能手环在确定出调节音量后，就可以根据该调节音量生成对应的音量调节指令，在生成音量调节指令后，智能手环将该音量调节指令发送至智慧屏设备，以便智慧屏设备进行音量调节。
S308、智慧屏设备响应于音量调节指令，调节该智慧屏设备的音量。
比如，如果音量调节指令用于指示增大该智慧屏设备的音量，则智慧屏设备增大该智慧屏设备的音量，比如智慧屏设备将智慧屏设备的目标音量增加上述调节音量得到音量值A，将音量值A作为播放内容时的音量。如果音量调节指令用于指示降低该智慧屏设备的音量，则智慧屏设备降低该智慧屏设备的音量，比如智慧屏设备将智慧屏设备的目标音量减去上述调节音量得到音量值B，将音量值B作为播放内容时的音量。
在实际应用中，智能手环还可以根据用户是否在打电话来确定需不需要调节智慧屏设备的播放音量。即智能手环在检测到用户在打电话时，不调节智慧屏设备的播放音量。智能手环在检测到用户没有在打电话时，可以根据目标音量、接收音量以及用户侧噪声大小来确定出调节音量。
除此之外，智能手环还可以实时检测用户与智慧屏设备之间的距离，当检测到用户与智慧屏设备之间的距离越来越小的时候，智慧屏设备可以判断智慧屏设备的播放音量是否太大，如果智慧屏设备的播放音量太大就生成降低智慧屏设备的播放音量的音量调节指令来控制智慧屏设备的播放音量。调节的音量可以根据用户于智慧屏设备之间的距离和智慧屏设备当前的播放音量来确定，具体不加以限制。
在本申请的一个可能实施例中，智能手环在向智慧屏设备发送音量调节指令之前，该智能手环还可以通过提示信息提示是否调节智慧屏设备的音量。之后，智能手环根据用户针对该提示信息的反馈消息，决定是否向智慧屏设备发送音量调节指令。
如图4所示，在智能手环计算得到调节音量之后，智能手环在其显示屏上显示提示框400。该提示框400用于提示是否调整智慧屏设备的音量。如果智能手环检测到控件401“是”被触发，则确定调节智慧屏设备的音量，因此，智能手环向智慧屏设备发送音量调节指令。如果智能手环检测到控件402“否”被触发，则确定不调节智慧屏设备的音量，因此，智能手环向智慧屏设备发送音量调节指令。比如如果用户确定智慧屏设备以当前音量(即目标音量)播放媒体内容时，对于用户而言其可以清楚地听到智慧屏设备播放的内体内容的声音，或者用户当前在拨打电话，则用户可以触发控件402“否”。如果用户确定当前确实无法听清楚智慧屏设备播放的内体内容的声音，则可以触发控件401“是”。该方法可以基于用户的需求来实现是否对智慧屏设备的音量的调整，提高了用户的体验。
值得说明的是，如果智能手环在指定时间内(比如，5秒或者10秒)未检测到控件402“否”或控件401“是”被触发，则智能手环默认发送音量调节指令，或者默认不发送音量调节指令。
在本申请的一个实施例中，如果智能手环还与用户的手机连接，如果智能手环检测到用户当前正在拨打电话，为了不影响用户打电话时的收听效果，智能手环可以向智慧屏设备发送音量调节指令，该音量调节指令用于指示智慧屏设备降低该智慧屏设备的播 放音量。作为一种示例，该音量调节指令中可以携带第一音量值，该第一音量值可以为系统默认的值，这样智慧屏设备在接收到该第一音量值之后便可以将智能屏设备的当前音量减少第一音量值。另外，如果智能手环检测到用户拨打电话结束，则智能手环可以向智慧屏设备发送音量调节指令，该音量调节指令用于指示智慧屏设备增大该智慧屏设备的播放音量。作为一种示例，该音量调节指令用于指示智慧屏设备将智慧屏设备的播放音量调整至第二音量值。该第二音量值为用户在智慧屏设备中设置的偏好音量值，或者第二音量值为用户在智能手环中设置的偏好音量值，或者第二音量值为用户拨打电话之前，该智慧屏设备播放内容时的音量值。
值得说明的是，如果智能手环检测到用户当前正在拨打电话，在向智能电视发送音量调节指令之前也可以通过如图4所示的方式提示用户，此处不再赘述。
在本申请的一个实施例中，智慧屏设备在调节播放音量之后可以将调节后的播放音量作为目标音量主动发送给智能手环。
在本申请的一个实施例中，智能手环在发送音量调节指令之后的一定时间内向智慧屏设备发送指令，该指令用于请求智慧屏设备向智能手环发送更新后的目标音量。
以上可以看出，本申请实施例提供的调节音量的方法，通过根据用户侧环境噪声、目标音量以及用户一侧接收到的音量最终确定出音量调节指令，能够有效地将智慧屏设备播放的音频信号的音量调节到用户能够听清的程度，使得音量调节方案更具鲁棒性，使得用户能够清晰地听到智慧屏设备播放的声音，解决了目前的调节音量的方法存在的音量调节效果不佳的问题。
此外，由于智能手环等可穿戴设备的处理器通常配置不高，因此导致智能手环等可穿戴设备的计算能力或者处理能力不强，很难在智能手环等可穿戴设备中部署上述信号分离(根据采集的到的声音信号分离出用户侧环境噪声和智能手环接收到的智慧屏设备播放的声音信号)，音量调节(根据目标音量和智能手环接收到的智慧屏设备播放的声音信号的音量(接收音量)确定出调节基数，再在调节基数的基础上考虑用户侧环境噪声确定出最终的调节音量)等功能。因此，本申请实施例还提供了另一种调节音量的方法，通过引入计算能力或者处理能力更强的设备(例如手机)来部署上述几个功能，通过手机执行信号分离和确定调节音量的步骤，同样能够提高音量调节的有效性，与此同时还能解决手环等可穿戴设备计算能力或者处理能力弱无法部署上述功能的问题。以下将结合附图对本申请实施例提供的另一种调节音量的方法进行详细说明。
请参阅图5，图5示出了本申请实施例提供的调节音量的方法所适用的另一场景示意图。如图5所示，该场景与图1所示的场景的区别在于，还包括：电子设备300。其中，电子设备300与可穿戴设备200之间具有通信连接。
可穿戴设备200与电子设备300之间建立通信连接的方式可以参考上述实施例中的内容，此处不再赘述。
在本申请另一场景中，上述媒体播放设备100与电子设备300之间也可以具有通信连接。
在本申请实施例中，上述电子设备300可以是硬件配置高于可穿戴设备的电子设备，例如手机、笔记本电脑，台式电脑、平板电脑等。本申请实施例对电子设备300的具体形态不作过多限制。
下述以媒体播放设备100为智慧屏设备，可穿戴设备200为智能手环，电子设备300 为手机为例，对本申请实施例提供的一种音量的调节方法进行描述。
图6为本申请实施例提供的另一种音量的调节方法的流程示意图，该方法包括：
S601、智能手环与手机建立通信连接，智能手环与智慧屏设备建立通信连接。
关于智能手环与手机，智能手环与智慧屏设备建立通信连接的方式可以参考上述实施例中的描述，此处不再赘述。
S602～S603、同上述S302～S303，此处不再赘述。
S604、智能手环通过与手机之间的通信连接向手机发送目标音量和该智能手环采集到的音频信号，相应的，手机接收来自智能手环的目标音量和音频信号。
S605、手机对音频信号进行分离，进而分离出智能手环采集到的噪声信号和智能手环采集到的所述媒体播放设备在播放所述内容时的声音信号。
关于S605的实现可以参考上述S305处的描述，此处不再赘述。
S606、手机根据智能手环采集到的噪声信号确定用户侧噪声强度，以及根据智能手环采集到的所述媒体播放设备在播放所述内容时的声音信号确定接收音量。
S607、手机根据目标音量、用户侧噪声强度以及接收音量确定出调节音量。
关于S607的实现可以参考上述S306处的描述，此处不再赘述。具体的可以将S306处智能手环确定调节音量的具体实现中的执行主体由智能手环更新为手机即可。
S608、手机通过与智能手环之间的通信连接将调节音量发送给智能手环，相应的，智能手环通过与手机之间的通信连接可以接收来自手机的调节音量。
S609、智能手环向智慧屏设备发送音量调节指令。其中，音量调节指令包括调节音量，音量调节指令用于触发智慧屏设备调节智慧屏设备的音量。
关于S609的实现可以参考上述S307处的描述，此处不再赘述。
S610、同上述S308处的描述，此处不再赘述。
值得说明的是，在手机和智慧屏设备之间具有通信连接的情况下，上述S608和S609可以由以下步骤代替：手机向智慧屏设备发送音量调节指令。其中，音量调节指令包括调节音量，音量调节指令用于触发智慧屏设备调节智慧屏设备的音量。
以上可以看出，本申请实施例提供的调节音量的方法，通过使用计算能力或者处理能力更强的设备来进行信号分离和确定调节音量，既能够实现上一实施例的音量调节效果，又能够解决手环等智能穿戴设备计算能力或处理能力弱的问题。
