当已连接设备选项247A中一个或多个电子设备选择控件对应的电子设备处于选中状态，且第一电子设备100检测到作用在确定控件247C的用户操作，第一电子设备100可以向上述一个或多个电子设备发送用于开启音频采集装置，采集环境声音的指令。
可用设备选项247B中可包含第一电子设备100发现可以建立通信连接但当前还未建立通信连接的电子设备选择控件。例如，第一电子设备100在扫描附近的蓝牙设备时，发现了设备名称为“Device201”的第四电子设备201(如耳机)、设备名称为“Device301”的第五电子设备301(如手机)。第一电子设备100与第四电子设备201、第五电子设备301从未建立过蓝牙连接。可用设备选项247B中可包含第四电子设备选择控件和第五电子设备选择控件。
当已连接设备选项247B中一个或多个电子设备选择控件对应的电子设备处于选中状态，且第一电子设备100检测到作用在确定控件247C的用户操作，第一电子设备100可以先与这一个或多个电子设备建立通信连接。例如，第一电子设备100可以向这一个或多个电子设备发送蓝牙连接请求，并在收到这一个或多个电子设备回复的同意连接消息后与这一个或多个电子设备建立蓝牙连接。这一个或多个电子设备在收到来自第一电子设备100的蓝牙连接请求后，可以显示如图3C所示的提示框232或者通过语音提示等方式来提示用户第一电子设备100请求建立蓝牙连接。
当第一电子设备100与这一个或多个电子设备建立了通信连接，第一电子100可以向这一个或多个电子设备发送用于开启音频采集装置，采集环境声音的指令。
也即是说，用户可以选择已连接设备选项247A和可用设备选项247B中的一个或多个电子设备选择控件对应的电子设备作为协同设备。
示例性的，第一电子设备100在接收到作用在确定控件247C上的用户操作时，确定第二电子设备选择控件对应的第二电子设备200处于选中状态。第一电子设备100可以向第二电子设备200发送用于开启音频采集装置，采集环境声音的指令。第二电子设备200接收到上述指令后可以开启音频采集装置，采集第二电子设备200所在位置处的环境声音，得到环境音频。
另外，第一电子设备100可以开始播放音频(如名称为“音乐A”的音乐)，并显示如图4D所示的用户界面240。在图4D中，用户界面240可包含上一首控件243、下一首控件245和暂停播放控件248。上述暂停播放控件248可用于第一电子设备100暂停播放音乐A。

其中，音效评估的方法以及第一电子设备100根据音效评估结果调节第一音频的播放音效的方法将在后续实施例中具体介绍，这里先不展开。
在一些实施例中，在检测到开始播放音频时，第一电子设备100可以确定智能音效模式 处于开启状态。则第一电子设备100可以显示如图4C所示的用户界面240，来指示用户选择协同设备采集自己所在位置处的环境声音。也即是说，第一电子设备100可以不再显示如图3B所示的用户界面，询问用户是否开启智能音效模式。
在一些实施例中，第一电子设备100可以根据设备类型确定与自己建立有通信连接的电子设备中用户随身携带可能性最高的电子设备，并指示该电子设备采集环境声音。
第一电子设备100中可存储有第一优先级规则。在各类型的电子设备中，可穿戴设备(如手表)为用户随身携带的可能性是最高的。其次，用户随身携带的电子设备还可以是手机。该第一优先级规则可以为可穿戴设备的优先级高于手机的优先级。也即是说，当与第一电子设备100建立通信连接的电子设备中包括手表和手机时，第一电子设备100可以优先向手表发送开启音频采集装置、采集环境声音的指令。
本申请实施例对上述第一优先级规则的具体内容不作限定。上述第一优先级规则可以是第一电子设备100在出厂时预置在存储器中的。或者，上述第一优先级规则可以是由用户设定的。
图5A和图5B示例性示出了第一电子设备100指示第二电子设备200开启音频采集装置的示意图。
如图5A所示，第一电子设备100可以接收到播放音乐A的用户操作。其中，第一电子设备100可以显示如图5A所示的用户界面240。该用户界面240包含的内容可以参考前述图4A所示用户界面240的介绍，这里不再赘述。
当接收到上述播放音乐A的用户操作，第一电子设备100可以开始播放音乐A。并且，第一电子设备100可以根据上述第一优先级规则来判断当前与自己建立有通信连接的电子设备中，优先级最高的电子设备。其中，第一电子设备100可以确定出第二电子设备200(即手表)的优先级最高。第一电子设备100可以向第二电子设备200发送开启音频采集装置的指令。
当接收到上述开启音频采集装置的指令，第二电子设备200可以显示如图5B所示的用户界面250。用户界面250可包括提示框251。该提示框251可用于询问用户是否开启第二电子设备200的麦克风。
提示框251可包括文字提示“Device100智能调节音效请求协同，是否开启麦克风？”，来提示用户设备名称为“Device100”的第一电子设备100在智能调节音效的过程中需要第二电子设备200开启音频采集装置，采集环境声音。本申请实施例对上述文字提示的具体内容不作限定。
提示框251还可以包括拒绝控件251A和同意控件251B。该拒绝控件251A可用于拒绝第一电子设备100开启麦克风的请求。响应于作用在该拒绝控件251A的用户操作，第二电子设备200可以向第一电子设备100发送拒绝开启麦克风的消息。该同意控件251B可用于同意第一电子设备100开启麦克风的请求。响应于作用在该同意控件251B的用户操作，第二电子设备200可以开启麦克风，并向第一电子设备100发送指示麦克风已开启的消息。
在一些实施例中，当接收到来自第二电子设备200指示麦克风已开启的消息，第一电子设备100可以获取第二电子设备200在第一时间段内采集的环境音频，并评估自己在第一时间段内播放的第一音频在第二电子设备200所在位置处的收听音效是否达到最佳音效。进一步的，第一电子设备100可以根据音效评估结果调节第一时间段下一时间段内第一音频的播放音效，使得播放的第一音频在第二电子设备200所在位置处的收听音效达到最佳音效。
在一些实施例中，当接收到来自第二电子设备200拒绝开启麦克风的消息，第一电子设备100可以根据上述第一优先级规则确定与自己建立有通信连接的电子设备中优先级次于第二电子设备200的电子设备，例如第三电子设备300。第一电子设备100可以向第三电子设备300发送开启音频采集装置的指令。可选的，若第一电子设备100在向第二电子设备200发送开启音频采集装置的指令后的预设时间段内，未接收到第二电子设备200的回复消息，第一电子设备100也可以根据上述第一优先级规则确定与自己建立有通信连接的电子设备中优先级次于第二电子设备200的电子设备，例如第三电子设备300。第一电子设备100可以向第三电子设备300发送开启音频采集装置的指令。
在一些实施例中，第一电子设备100可以在与自己建立有通信连接的电子设备中，向所有具有音频采集装置的电子设备发送开启音频采集装置的指令。当接收到上述开启音频采集装置的指令，这些电子设备可以显示如图5B所示的提示框250或者通过语音提示等方式来提示用户第一电子设备100请求开启对应电子设备的音频采集装置。这些电子设备中的一个或多个在接收到同意开启音频采集装置的用户操作后，可以开启音频采集装置并向第一电子设备100发送指示音频采集装置已开启的消息。根据这一个或多个电子设备采集的环境音频以及第一电子设备100播放的第一音频得到的音效评估结果，第一电子设备100可以调节自己播放第一音频的播放音效。
也即是说，用户可以在多个接收到上述开启音频采集装置的指令的电子设备(如手表、手机等)中选择一个或者多个电子设备开启音频采集装置，来协助第一电子设备100智能调节音效。
其中，被选择的多个电子设备可以是多个用户随身携带的电子设备。例如，第一用户的手表和第二用户的手表均开启麦克风采集自己所在位置的环境声音。根据这两个电子设备采集得到的环境音频以及第一电子设备100播放的第一音频的音效评估结果，第一电子设备100可以调节自己播放第一音频的播放音效，使得第一音频在第一用户所在位置处的收听音效和在第二用户所在位置处的收听音效均与最佳音效接近。即第一用户和第二用户在收听第一电子设备100播放的音频时均能有较好的听感。
下面介绍音效评估模块基于第一音频和环境音频得到音效评估结果的实现方法。
在第一电子设备100播放第一音频的过程中，第二电子设备200可以采集到的环境声音主要包括第一音频播放的声音以及第二电子设备200附近的背景噪声。则第二电子设备200采集得到的环境音频主要包括播放音频部分和背景噪声部分。上述播放音频部分的音频信号来自于上述第一音频播放的声音。上述背景噪声部分的音频信号来自于第二电子设备200附近的背景噪声。
音效评估模块可以对上述环境音频进行声源分离，将环境音频分为播放音频部分和背景噪声部分这两部分音频。
在一种可能的实现方式中，音效评估模块可以利用谱减法分离出环境音频中的背景噪声部分。具体的，环境音频是播放音频部分的音频信号与背景噪声部分的音频信号的叠加。即背景噪声是加性噪声。在假定播放音频部分与背景噪声部分不相关，且背景噪声是平稳或者缓慢变化的情况下，音效评估模块可以估计上述背景噪声部分的频谱。进一步的，音频评估模块可以用环境音频的频谱减去背景噪声部分的频谱，得到播放音频部分的频谱。这样，音效评估模块可以实现环境音频的声源分离。
上述谱减法的实现方法简单、运算量小。音效评估模块利用谱减法可以实现快速分离环境音频中的播放音频部分和背景噪声部分，且得到的播放音频部分的音频信号具有较高的信噪比。
在一种可能的实现方式中，音效评估模块可以利用训练好的神经网络分离出环境音频中的背景噪声部分。具体的，神经网络可以是利用大量的训练样本训练好的。其中，一个训练样本可以由上述环境音频以及该环境音频的播放音频部分组成。训练好的神经网络可以接收环境音频，并输出该环境音频中的播放音频部分。这样，音效评估模块可以实现环境音频的声源分离。
神经网络训练的具体过程可以参考现有技术中训练神经网络的实现过程，本申请实施例对此不进行赘述。上述神经网络可以例如是卷积神经网络、深度神经网络。本申请实施例对上述神经网络的类型不作限定。
上述利用训练好的神经网络进行声源分离的实现方法需要经过大量运算以得到训练好的神经网络。训练好的神经网络可以较好地实现分离环境音频中的播放音频部分和背景噪声部分。
在一种可能的实现方式中，音效评估模块可以利用盲源分离法分离出环境音频中的背景噪声部分。具体的，上述第二电子设备200可以利用两个及以上的麦克风来采集环境声音，得到环境音频。由于不同来源的声音(如第一音频的声音、背景噪声中各声源的声音等)是不同的物理过程产生的，不同来源的声音之间是相互独立的。多个麦克风在采集环境声音时，同一个声源的声音被这多个麦克风采集得到的音频存在差异。根据多个麦克风采集得到的环境音频，音效评估模块可以确定环境声音中不同声音来源的方向(如第一音频的声音的方向、背景噪声中各声源的方向等)。进一步的，音效评估模块可以通过独立成分分析确定出环境音频中不同来源的声音对应的音频信号。这样，音效评估模块可以实现环境音频的声源分离。
上述利用盲源分离法的实现方法需要采集环境声音的电子设备具有至少两个麦克风。盲源分离法可以较好地实现分离环境音频中的播放音频部分和背景噪声部分。
音效评估模块可以采用上述一种或多种实现方式对环境音频进行声源分离。不限于上述声源分离的方法，音效评估模块还可以采集其它声源分离的方法从环境音频中分离出上述播放音频部分和上述背景噪声部分。
进一步的，音效评估模块可以获取上述第一音频在最佳音效下的音频信号。上述第一音频可以是第一电子设备100播放的音频文件，包含有待输出的音频信号。在一种可能的实现方式中，第一音频在经过扬声器输出前，可以存储在缓存区域中。电子设备可以从该缓存区域中提取上述第一音频，并将该第一音频交由音效评估模块。本申请实施例对音效评估模块获取第一音频的方式不作限定。当得到上述第一音频，音效评估模块可以根据最佳音效下各项音频参数的取值范围确定第一音频在最佳音效下的音频信号。
通过比较上述第一音频在最佳音效下的音频信号与播放音频部分的音频信号的差距，音效评估模块可以得到音效评估结果。该音效评估结果可用于指示用户的收听音效与最佳音效之间的差距。其中，上述收听音效与最佳音效之间的差距具体可以指以收听音效播放第一音频时对应的音频参数与以最佳音效播放第一音频时对应的音频参数之间的差距。例如，以收听音效播放第一音频时，响度为50分贝。以最佳音效播放第一音频时，响度为60分贝。则上述收听音效与最佳音效之间的差距可以包括音频参数中响度的差距，即10分贝的差距。不限于上述响度。上述收听音效与最佳音效之间的差距还可以包括音频参数中其它参数在数值上的差距。例如，EQ中中心频率的差距、增益的差距，DRC中频带范围的差距、压缩率的 差距等等。
在一些实施例中，音效评估模块可以得到多个环境音频。这多个环境音频可以分别由多个不同的电子设备采集得到(例如多个用户随身携带的电子设备)。音效评估模块可以对这个多个环境音频进行声源分离，并比较上述第一音频在最佳音效下的音频信号与这多个环境音频中播放音频部分的音频信号的差距，得到音效评估结果。也即是说，该音效评估结果可以指示多个用户的收听音效与最佳音效之间的差距。
音效评估模块可以配置在第一电子设备100、第二电子设备200、第三电子设备300等电子设备的一个或多个电子设备中。本申请实施例对此不作限定。
下面介绍音效调节模块基于音效评估结果调节第一音频的播放音效的实现方法。
第一电子设备100的处理器110中可集成有音效调节模块。该音效调节模块可以对第一电子设备100播放音频的响度进行调节。该音效调节模块中可包含有EQ组件、DRC组件等调节音频信号的组件。通过上述EQ组件、DRC组件，音效调节模块可以对第一音频应用均衡、动态范围控制等效应，以调节第一音频的播放音效。
音效调节模块可以获取上述音效评估模块的音效评估结果。若音效评估结果指示收听音效与最佳音效之间的差距小于预设的阈值，音效调节模块可以保持当前各项音频参数不变。若音效评估结果指示收听音效与最佳音效的差距大于上述预设的阈值，音效调节模块可以对各项音频参数进行调节，改变第一音频的播放音效，使得用户的收听音效与最佳音效之间的差距小于上述预设的阈值。音效调节模块可以利用调节后的各项音频参数对第一音频进行处理，并将处理得到的音频信号交由扬声器。扬声器可以播放上述经过处理得到的音频信号。
在一些实施例中，上述音效评估结果中可包含有多个电子设备所在位置处的收听音效与最佳音效之间的差距。当得到该音效评估结果，音效调节模块可以计算多个电子设备所在位置处的收听音效与最佳音效之间的差距的均值。然后，音效调节模块可以根据上述计算得到的均值对各项音频参数进行调节，改变第一音频的播放音效。这样，第一电子设备100可以使得在上述多个电子设备所在位置处的用户收听第一音频时均能有较好的听感。
由上述方法可知，第一电子设备100可以根据第二电子设备200采集的环境音频确定用户收听第一音频的收听音效。进而，第一电子设备100可以在播放第一音频的过程中动态调节音频参数，减少用户的收听音效受用户与第一电子设备100的距离变化、角度变化和背景噪声变化等因素的影响，使得用户的收听音效可以达到或者接近最佳音效。
在一些实施例中，音效调节模块还可以根据从环境音频中分离出来的背景噪声部分的音频信号调节播放第一音频的响度。例如，背景噪声部分的音频信号的幅值越高(即背景噪声越大)，音效调节模块调节第一音频在播放过程中响度的调节量可以越大。
可以理解的，当用户所处位置的背景噪声越大，第一电子设备100可以将响度调高，以免背景噪声将第一电子设备100播放的第一音频的声音淹没。
在一些实施例中，当从环境音频中分离出播放音频部分和背景噪声部分，音效评估模块还可以评估背景噪声部分是否包含人声。若确定出背景噪声部分包含人声，音效评估模块可以向音效调节模块发送指示背景噪声部分包含人声的消息。进一步的，音效调节模块可以保持播放第一音频的响度不变，或者降低播放第一音频的响度。
可以理解的，在上述背景噪声部分包含人声时，用户与他人聊天或正在打电话的可能性 较高。第一电子设备100保持播放第一音频的响度不变或者降低响度可以降低第一音频播放对用户聊天或打电话的影响，以免第一音频的声音干扰用户说话的声音。
本申请实施例对上述评估背景噪声部分是否包含人声的具体方法不作限定，例如，音效评估模块可以利用支持向量机算法来识别背景噪声部分的音频信号中是否包含人声。上述评估背景噪声部分是否包含人声的具体过程可参考现有技术中识别音频中是否包含人声的实现过程。
下面基于第一电子设备100评估并调节音效，第二电子设备200采集环境声音的场景介绍本申请实施例提供的一种音效调节方法。
图6示例性示出了本申请实施例提供的一种音效调节方法的流程图。如图6所示，该方法可包括步骤S101～S110。该方法以第一电子设备100与附近的电子设备建立蓝牙连接为例进行说明。其中：
