具体实施方式
为了更好的理解本申请实施例公开的一种声音处理方法，下面首先对本申请实施例适用的应用场景进行描述。
请参见图1a，为本申请实施例提供的一种终端设备的屏幕显示参数满足声音调整条件的场景示意图。其中，该终端设备可以包括多个声音配置参数组，该终端设备还可以包括一个或多个声音输入输出设备组，图1a中以终端设备包括一个声音输入输出设备组为例进行说明。每个声音配置参数组可以用于对对应的声音输入输出设备组进行配置，以使该声音输入输出设备组播放的声音效果或者采集的声音效果满足用户需求。需要说明的是，一个声音输入输出设备组可以对应多个声音配置参数组。
其中，声音配置参数组可以包括但不限于智能功率放大器(smart power amplifier，smartpa)的参数、升压参数(如boost参数)、数字化影院系统(digital theater systems，DTS)算法的参数或杜比音效算法的参数中的一种或多种。其中，DTS是一种用于电影和音乐的高质量多音轨环绕声技术。杜比音效(Dolby Audio)技术是一系列用于为影院、家庭和途中提供丰富、清晰且撼人心魄的音效的环绕声技术。杜比音效算法的参数可以包括但不限于实现降噪的相关参数、实现均衡的相关参数、实现定向环绕的相关参数或实现全景声的相关参数中的一种或多种。
声音输入输出设备组由声音输入设备和声音输出设备组成，一个声音输入输出设备组可以包括一个或多个声音输入设备，一个声音输入输出设备组可以包括一个或多个声音输出设备。其中，声音输入设备可以包括麦克风，声音输出设备可以包括扬声器。扬声器可以包括喇叭或听筒。需要说明的是，声音配置参数组可以包括对声音输入输出设备组中的各个设备进行配置所采用的参数，例如，声音配置参数组可以包括声音配置参数1、声音配置参数2和声音配置参数3。其中，声音配置参数1可以用于对喇叭进行配置，声音配置参数2可以用于对听筒进行配置，声音配置参数3可以用于对麦克风进行配置。
在本申请实施例中，终端设备可以检测终端设备的屏幕显示参数是否满足声音调整条件，并在检测到终端设备的屏幕显示参数满足声音调整条件的情况下，获取当前的屏幕显示参数；然后根据当前的屏幕显示参数从终端设备中的多个声音配置参数组中确定第一声音配置参数组；并将第二声音配置参数组更新为该第一声音配置参数组，该第二声音配置参数组为该终端设备当前启用的声音配置参数组。
其中，终端设备的屏幕显示参数可以包括屏幕模式，该屏幕模式可以为竖屏模式或横屏模式。终端设备的屏幕显示参数满足声音调整条件可以表明：采用该终端设备当前启用的声音配置参数组对声音输入输出设备组进行配置后得到的声音效果与当前应用场景不匹配，即当前播放的音效或者采集的音效不是最佳音效，用户不能获得最佳的听感体验。因此，终端设备可以根据当前的屏幕显示参数从终端设备中的多个声音配置参数组中确定第一声音配置参数组，终端设备启用该第一声音配置参数组对声音输入输出设备组进行配置后得到的声音效果可以更好地匹配当前应用场景。通过这种方式，可以灵活地调节音频效果，提高终端设备的智能性、灵活性，还有利于提高用户的听感体验。终端设备的屏幕模式发生变化，可以使得该终端设备的屏幕显示参数满足声音调整条件。例如，该终端设备 的屏幕模式由横屏模式变为竖屏模式，或者，该终端设备的屏幕模式由竖屏模式变为横屏模式。前述当前的屏幕显示参数可以包括该终端设备的屏幕模式发生变化之后所采用的屏幕模式。
如图1a所示，终端设备100的屏幕模式由左图中的竖屏模式变化为右图中的横屏模式的情况下，该终端设备100的屏幕显示参数满足声音调整条件。图1a(左图和右图)中的终端设备100包括一个声音输入输出设备组(图未示)，该声音输入输出设备组包括喇叭101、听筒102和麦克风103。终端设备100的屏幕还包括时间图标、通信信号图标、无线局域网(wireless local area networks，WLAN)(如无线保真(wireless fidelity，Wi-Fi)网络连接状态图标、电池图标以及播放视频时所显示的返回图标、播放进步图标、暂停图标、播放下一个视频的控制图标等。
由图1a中左图可知，此时，终端设备100以竖屏模式播放猫和老鼠视频。由图1a中右图可知，此时，终端设备100以横屏模式播放该视频。可以理解的是，终端设备处于横屏模式下，可以认为用户对终端设备的音频效果的要求高于处于竖屏模式下对终端设备的音频效果的要求。因此，终端设备处于横屏模式下，采用使得音效更好的声音配置参数组，有利于增强用户在横屏模式下的沉浸感。例如，若终端设备100包括声音配置参数组1和声音配置参数组2，使用声音配置参数组1对应产生的音效比使用声音配置参数组2对应产生的音效差。若终端设备100的当前屏幕模式为横屏模式，则终端设备100可以将声音配置参数组2作为第一声音配置参数组；若终端设备100的当前屏幕模式为竖屏模式，则终端设备100可以将声音配置参数组1作为第一声音配置参数组。相较于横屏模式，可以认为处于竖屏模式下用户对终端设备的音频效果的要求较低，因此，采用使音效效果一般的声音配置参数组1，用户几乎不会感觉到听感降低，而且采用使音效效果一般的声音配置参数组1，可以降低终端设备的资源消耗。
需要说明的是，图1a中终端设备100包括一个声音输入输出设备组仅用于举例，并不构成对本申请实施例的限定。在其他可行的实现方式中，终端设备100还可以包括多个声音输入输出设备组。图1a中一个声音输入输出设备组包括一个喇叭101、一个听筒102和一个麦克风103仅用于举例，并不构成对本申请实施例的限定。在其他可行的实现方式中，该声音输入输出设备组还可以包括副麦克风。还需要说明的是，图1a中喇叭101、听筒102和麦克风103在终端设备100中的位置仅用于举例，并不构成对本申请实施例的限定。
其中，该终端设备100可以是基于人工智能的终端设备，终端设备100也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、智能电视、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
人工智能(artificial intelligence，AI)是研究、开发用于模拟、延伸和扩展人的智能的 理论、方法、技术及应用系统的一门新的技术科学。AI的核心是使用机器学习技术，以允许机器模拟人类行为的某些核心方面。换言之，AI允许机器表现为能够在很少或没有人为干预的情况下感知、学习、做出决策、以及采取行动的自主系统。

下面结合附图对本申请提供的声音处理方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种声音处理方法的流程示意图，该方法应用于包括多个声音配置参数组的终端设备。该声音处理方法的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为声音处理方法的执行主体为例进行说明。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：在终端设备的屏幕显示参数满足声音调整条件的情况下，该终端设备获取当前的屏幕显示参数。
在本申请实施例中，终端设备可以实时、周期或不定期检测终端设备的屏幕显示参数是否满足声音调整条件，并在检测到终端设备的屏幕显示参数满足声音调整条件的情况下，获取当前的屏幕显示参数。
终端设备的屏幕显示参数满足声音调整条件可以包括：终端设备的屏幕显示参数发生变化，即终端设备的历史屏幕显示参数和当前的屏幕显示参数不同。终端设备的屏幕显示参数满足声音调整条件可以表明：采用该终端设备当前启用的声音配置参数组对该终端设备中的声音输入输出设备组进行配置后得到的声音效果与当前应用场景不匹配，即终端设备可以切换该终端设备当前启用的声音配置参数组，以调节终端设备的音频效果。换言之，终端设备的屏幕显示参数满足声音调整条件，表明需要切换终端设备当前启用的声音配置参数组。
具体的，屏幕显示参数可以包括屏幕模式。终端设备的屏幕模式发生变化，可以使得该终端设备的屏幕显示参数满足声音调整条件。在一种实现方式中，该终端设备在运行音频类应用的过程中该终端设备的屏幕模式发生变化，可以使得该终端设备的屏幕显示参数满足声音调整条件。音频类应用可以为具备声音采集功能和/或声音播放功能的应用，或者音频类应用可以为声音功能为应用的主要功能的应用(如通话应用)，或者音频类应用可以为对声音要求较高的应用(如视频播放器、音乐播放器等)。非音频类应用可以既不具备声音采集功能也不具备声音播放功能。通过这种方式，在终端设备运行非音频类应用的过程中该终端设备的屏幕模式发生变化的情况下，该终端设备可以不用切换该终端设备当前启用的声音配置参数组。因为运行非音频类应用的过程中，终端设备除了输出消息提示音、电话响铃等不需要较高音效的声音外，不需要输出其他对于音效较高的声音，所以在该情况下，不切换该终端设备当前启用的声音配置参数组，有利于避免资源浪费。
在一种实现方式中，终端设备可以默认设置声音调整条件，也可以由用户自定义或者 更改设置的声音调整条件。在一种实现方式中，用户可以根据自身需要(如使用习惯)在终端设备中设置声音调整条件，即用户可以自定义在哪些情况下可以切换终端设备所启用的声音配置参数组。
在一种实现方式中，基于人工智能的终端设备可以根据用户在该终端设备上的历史操作信息，确定屏幕显示参数以及声音调整条件。例如，若历史操作信息指示终端设备的屏幕模式发生变化的情况下，用户在终端设备中输入预设操作以切换终端设备所启用的声音配置参数组。通过该历史操作信息，可以理解的是，终端设备的屏幕模式发生变化的情况下，用户希望改变终端设备所启用的声音配置参数组。基于此，基于人工智能的终端设备可以自动设置终端设备的屏幕显示参数满足声音调整条件包括：终端设备的屏幕模式发生变化。通过这种方式，可以使得设置的声音调整条件更好地匹配用户需求，避免用户手动切换终端设备所启用的声音配置参数组，即可以更加灵活地切换终端设备所启用的声音配置参数组，并能更快速地实现声音配置参数组的切换，从而有利于提高终端设备的智能性和灵活性。
需要说明的是，历史操作信息可以存储于云端也可以存储于终端设备。终端设备通过记录用户的历史操作信息，可以了解该用户使用该终端设备的习惯，而无需频繁调用云端中存储的数据。这样终端设备在不使用网络的情况下也可以确定用户的使用习惯。还需要说明的是，终端设备可以针对不同用户的历史操作信息，确定针对不同用户的声音调整条件。进而在不同用户使用该终端设备时通过对应的声音调整条件确定是否可以切换终端设备所启用的声音配置参数组。例如，两用户使用终端设备的习惯不同时，若终端设备的屏幕模式发生变化，且当前使用该终端设备的是第一个用户，则终端设备可以切换终端设备所启用的声音配置参数组；若当前使用该终端设备的是第二个用户，则终端设备可以不切换终端设备所启用的声音配置参数组。通过这种方式，可以提高终端设备的智能性和灵活性，使得终端设备可以更好地匹配不同用户的使用习惯，并使得不同用户在使用该终端设备时都能获得良好的使用体验。
在一种实现方式中，屏幕显示参数可以包括终端设备中运行的音频类应用的播放模式。例如，音频类应用为视频应用a时，视频应用a的播放模式可以为全屏播放模式或非全屏播放模式。播放模式为全屏播放模式时，视频应用a播放的内容可以占用或几乎占用(一小部分屏幕可以用于显示一些系统图标、应用图标)整个屏幕。如图1a中的右图所示。需要说明的是，即使终端设备处于竖屏模式，若该终端设备中运行的视频应用a处于全屏播放模式，那么该视频应用a的内容也可以占用整个屏幕。播放模式为非全屏播放模式时，视频应用a播放的内容占用部分屏幕。如图1a中的左图所示，终端设备的屏幕显示参数满足声音调整条件可以包括：该终端设备中运行的音频类应用(播放猫和老鼠的视频应用)的播放模式发生变化。例如，该音频类应用的播放模式由全屏播放模式变为非全屏播放模式，或者，该音频类应用的播放模式由非全屏播放模式变为全屏播放模式。
在本申请实施例中，终端设备可以通过获取当前的屏幕显示参数，并根据当前的屏幕显示参数从终端设备包括的多个声音配置参数组中确定第一声音配置参数组。具体的，当前的屏幕显示参数可以包括终端设备当前所处的屏幕模式。以图1a为例，左图中的终端设备100所处的屏幕模式(竖屏模式)为终端设备的历史屏幕模式，右图中的终端设备100 所处的屏幕模式(横屏模式)为终端设备当前所处的屏幕模式。或者，当前的屏幕显示参数可以包括终端设备中运行的音频类应用的当前播放模式。
需要说明的是，在本申请实施例中提及屏幕中运行的应用表示：终端设备中运行有该应用，且该应用的数据显示在终端设备的屏幕上。
步骤S202：终端设备根据当前的屏幕显示参数从前述多个声音配置参数组中确定第一声音配置参数组。
具体的，终端设备可以根据屏幕显示参数与声音配置参数组之间的对应关系，将前述多个声音配置参数组中与当前的屏幕显示参数对应的声音配置参数组作为第一声音配置参数组。
在本申请实施例中，终端设备可以设置多种类型的屏幕显示参数，并分别设置各种类型的屏幕显示参数与声音配置参数组之间的对应关系。例如，终端设备包括声音配置参数组1和声音配置参数组2，终端设备设置的两种类型的屏幕显示参数为屏幕模式和终端设备中运行的音频类应用的播放模式(如视频应用a的播放模式)时，终端设备针对这两种类型的屏幕显示参数设置的对应关系分别如表1、表2所示：
表1 屏幕模式与声音配置参数组之间的对应关系
屏幕模式 声音配置参数组
竖屏模式 声音配置参数组1
横屏模式 声音配置参数组2
表2 视频应用a的播放模式与声音配置参数组之间的对应关系
视频应用a的播放模式 声音配置参数组
非全屏播放模式 声音配置参数组1
全屏播放模式 声音配置参数组2
需要说明的是，当终端设备设置多种类型的屏幕显示参数(如屏幕模式和终端设备中运行的视频应用a的播放模式)，且检测到终端设备的屏幕模式发生变化(即终端设备的屏幕显示参数满足声音调整条件)的情况下，终端设备可以获取当前的屏幕模式，并将当前的屏幕模式作为当前的屏幕显示参数。进而根据表1所示对应关系确定第一声音配置参数组。同理，若检测到终端设备中运行的视频应用a的播放模式发生变化(即终端设备的屏幕显示参数满足声音调整条件)的情况下，终端设备可以获取视频应用a当前的播放模式，并将视频应用a当前的播放模式作为当前的屏幕显示参数。进而根据表2所示对应关系确定第一声音配置参数组。
在本申请实施例中，终端设备可以预先设置屏幕显示参数与声音配置参数组之间的对应关系，终端设备也可以根据用户操作更改屏幕显示参数与声音配置参数组之间的对应关系。
步骤S203：终端设备将第二声音配置参数组更新为该第一声音配置参数组，该第二声音配置参数组为该终端设备当前启用的声音配置参数组。
其中，该第二声音配置参数组为检测到终端设备的屏幕显示参数满足声音调整条件时，该终端设备所启用的声音配置参数组。该第一声音配置参数组可以为检测到终端设备的屏 幕显示参数满足声音调整条件之后，该终端设备所启用的声音配置参数组。采用不同的声音配置参数组对终端设备进行配置，该终端设备采集声音的效果和/或播放声音的效果不同。因此，终端设备通过切换所启用的声音配置参数组，可以灵活地调节音频效果，使得终端设备的音频效果可以更好地适应不同的应用场景，从而有利于提高终端设备的智能性和灵活性，并有利于提高用户体验。
通过实施本申请实施例，在检测到终端设备的屏幕显示参数满足声音调整条件的情况下，获取当前的屏幕显示参数；然后根据当前的屏幕显示参数从终端设备中的多个声音配置参数组中确定第一声音配置参数组；并将第二声音配置参数组更新为该第一声音配置参数组，该第二声音配置参数组为该终端设备当前启用的声音配置参数组。通过切换终端设备启用的声音配置参数组，可以使得该终端设备采集声音的效果和/或播放声音的效果不同，即可以灵活地调节音频效果，从而有利于提高终端设备的智能性和灵活性。
请参见图3a，图3a是本申请实施例提供的另一种声音处理方法的流程示意图，该方法应用于包括多个声音配置参数组的终端设备。该方法详细描述了终端设备包括折叠屏时，在何种情况下屏幕显示参数满足声音调整条件。其中，该声音处理方法的执行主体为终端设备，或者为终端设备中的芯片，以下以终端设备为声音处理方法的执行主体为例进行说明。如图3a所示，该方法可以包括但不限于如下步骤：
步骤S301：在终端设备的屏幕显示参数满足声音调整条件的情况下，该终端设备获取当前的屏幕显示参数，其中，该终端设备包括第一屏幕和第二屏幕；该屏幕显示参数包括该第一屏幕和该第二屏幕之间的折叠角度，该屏幕显示参数满足声音调整条件包括：该折叠角度发生变化；当前的屏幕显示参数包括第一屏幕和第二屏幕之间当前的折叠角度。
在本申请实施例中，该终端设备包括折叠屏，该折叠屏可以包括一个或多个屏幕，该折叠屏经过折叠之后可以呈现为两个或两个以上屏幕，本申请实施例以该折叠屏经过折叠之后呈现为两个屏幕(如第一屏幕和第二屏幕)为例进行介绍。
该屏幕显示参数可以包括但不限于：屏幕模式，该终端设备中运行的音频类应用的播放模式，该第一屏幕和该第二屏幕之间的折叠角度，该第一屏幕上显示的内容对应的第一应用标识，该第二屏幕上显示的内容对应的第二应用标识或用户焦点所在屏幕的标识中的一种或多种。
其中，屏幕模式和该终端设备中运行的音频类应用的播放模式可参见图2中步骤S201的具体描述，此处不再赘述。该第一屏幕和该第二屏幕之间的折叠角度可以是[-180°，180°]中的任意角度。该第一屏幕上显示的内容可以是第一应用的内容，该第一应用的标识为该第一应用标识。该第二屏幕上显示的内容可以是第二应用的内容，该第二应用的标识为该第二应用标识。用户焦点所在屏幕的标识用于唯一标识用户焦点所在的屏幕。用户焦点所在屏幕可以为用户当前较为关注的屏幕。在一种实现方式中，终端设备可以将用户最新操作的屏幕作为用户焦点所在屏幕，或者，终端设备可以通过用户眼球确定该用户当前查看的屏幕，并将用户当前查看的屏幕作为用户焦点所在屏幕，本申请实施例对确定用户焦点所在屏幕的方式不作限定。
该屏幕显示参数满足声音调整条件包括如下情况中的一种或多种：1)该终端设备的屏 幕模式发生变化；2)该终端设备在运行音频类应用的过程中，该终端设备的屏幕模式发生变化；3)该终端设备中运行的音频类应用的播放模式发生变化；4)第一屏幕和该第二屏幕之间的折叠角度发生变化；5)该第一应用标识对应的应用类型发生变化，和/或该第二应用标识对应的应用类型发生变化；6)在该第一应用标识和该第二应用标识不同，且该第一应用标识和该第二应用标识对应的应用类型均为音频类的情况下，用户焦点所在屏幕的标识发生变化。其中，前3种情况可以参见图2中步骤S201的具体描述，此处不再赘述。
对于第4种情况：第一屏幕和第二屏幕之间的折叠角度发生变化。在一种实现方式中，只要第一屏幕和第二屏幕之间的折叠角度发生变化，即可以切换所启用的声音配置参数组，这样可以增加终端设备的趣味性。在一种实现方式中，第一屏幕和第二屏幕之间的折叠角度发生变化，且该折叠角度的变化量大于预设角度，可以使得屏幕显示参数满足声音调整条件。折叠角度的变化量大于预设角度，可以避免终端设备发生碰撞或因其他原因使折叠屏发生抖动时(此时用户并不希望调整终端设备的音效，即不需要切换终端设备所启用的声音配置参数组)，导致第一屏幕和第二屏幕之间的折叠角度发生变化，进而使终端设备切换所启用的声音配置参数组的情况，有利于避免误操作以及误操作带来的资源消耗。其中，预设角度可以由终端设备默认设置，也可以根据用户操作确定，且可以根据用户操作更改预设角度。预设角度可以为1°、2°或者其他较小的角度值。
在一种实现方式中，第一屏幕和第二屏幕之间的折叠角度的类型发生变化，可以使得屏幕显示参数满足声音调整条件。折叠角度的类型可以为第一类角度和第二类角度。折叠角度的类型发生变化可以包括：该折叠角度由第一类角度变为第二类角度，或者，该折叠角度由第二类角度和第一类角度。其中，第一类角度可以包括0°，第二类角度可以包括除0°以外的其他角度。换言之，终端设备处于非折叠状态下时，该终端设备的第一屏幕和第二屏幕之间的折叠角度的类型为第一类角度；终端设备处于折叠状态下时，该折叠角度的类型为第二类角度。以图3b所示的对终端设备100进行折叠的场景示意图为例，通过转动终端设备100中的转轴106，可以使第一屏幕104和第二屏幕105之间的折叠角度发生变化。当第一屏幕104和第二屏幕105合成为一个完整的屏幕(即第一屏幕和第二屏幕完全展开)时，折叠角度为0°。往屏幕的后方旋转可以使折叠角度增大。在一种实现方式中，往屏幕的前方旋转可以使折叠角度减小，且折叠角度为负数。在折叠角度的类型发生变化的情况下切换终端设备所启用的声音配置参数组，有利于节省终端设备的资源。例如，折叠角度由15°变化为30°的情况下，不改变终端设备所启用的声音配置参数组，可以节省资源。
当终端设备包括一个声音输入输出设备组，且该声音输入输出设备组中的喇叭、听筒和麦克风在该终端设备中所处的位置不变时，通过该声音输入输出设备组输入的声音效果或者输出的声音效果会随着第一屏幕和第二屏幕之间的折叠角度变化。声音效果可以包括但不限于：立体声的声场位置、功率(额定输出功率、音乐输出功率、峰值音乐输出功率)、频率范围与频率响应中的一种或多种。其中，额定输出功率指功放电路在额定失真范围内，能够持续输出的最大功率。也称有效功率。音乐输出功率指在失真不超过规定范围的情况下，功放电路的瞬间最大输出功率。峰值音乐输出功率指完全不考虑失真的情况下，功放的瞬间最大输出功率。频率范围与频率响应是标识音箱声音还原能力的两个基本参数，前 者是指音箱最低有效回放频率与最高有效回放频率之间的范围，单位赫兹(Hz)；后者是指将一个以恒电压输出的音频信号与音箱系统相连接时，音箱产生的声压随频率的变化而发生增大或衰减、相位随频率而发生变化的现象，这种声压和相位与频率的相关联的变化关系称为频率响应，单位分贝(dB)。
以图3c所示的终端设备播放视频时立体声的声场示意图为例，图3c中，第一屏幕104和第二屏幕(图3c未示)之间的折叠角度为180°，且终端设备100中只有第一屏幕104处于工作状态，在第一屏幕104中播放猫和老鼠视频时，喇叭101及听筒102立体声播放的声场107(图3c中黑色填充圆形)位于该第一屏幕104的中心。
当用户转动第二屏幕，使得第一屏幕和第二屏幕之间的折叠角度为0°之后，该终端设备可以在第一屏幕和第二屏幕组成的大屏幕上播放猫和老鼠视频，此时，该终端设备播放视频时立体声的声场示意图可以如图3d所示。由图3d可知，保持喇叭101及听筒102的位置与图3c中一致时，在第一屏幕104和第二屏幕105组成的大屏幕上播放视频时，喇叭101及听筒102立体声播放的声场107仍然位于第一屏幕104的中心。对于用户来说，会感觉视频播放的声音是从大屏幕的左侧(大屏幕左侧1/4处)发出的，而非该大屏幕的中心发出的，使得听感体验较差。
需要说明的是，终端设备通过改变启用的声音配置参数组，可以改变该终端设备的音频效果。或者，终端设备通过改变声音输入输出设备组中的喇叭、听筒、麦克风在终端设备中的位置，可以改变该终端设备的音频效果。本申请实施例以改变启用的声音配置参数组以改变该终端设备的音频效果为例进行说明。为了避免在图3d所示的场景示意图下用户的听感体验较差，终端设备可以切换所启用的声音配置参数组，以使图3d中的终端设备播放视频时立体声的声场位于大屏幕的中心。通过这种方式，可以更好地匹配不同的应用场景，有利于提高终端设备的音频效果。
还需要说明的是，图3b中所示终端设备包括一个转轴，且该转轴在终端设备的中间位置仅用于举例说明，在其他可行的实现方式中，终端设备可以包括多个转轴，该多个转轴可以按需设置在终端设备中的任意位置。可选的，终端设备可以包括无限个转轴，即可以在任意位置处折叠终端设备的屏幕。还需要说明的是，图3b所示第一屏幕和第二屏幕的尺寸相同仅用于举例，并不构成对本申请实施例的限定，在其他可行的实现方式中，第一屏幕和第二屏幕的尺寸可以不同。其中，屏幕的尺寸可以指屏幕的长度、宽度和长宽比中的一种或多种。
在一种实现方式中，第一屏幕和第二屏幕之间的折叠角度的类型发生变化，且该折叠角度的变化量大于前述预设角度，可以使得屏幕显示参数满足声音调整条件。通过这种方式，有利于避免误操作以及误操作带来的资源消耗。
对于第5种情况：第一应用标识为第一屏幕中运行的应用的标识，需要说明的是，当第一屏幕中仅显示系统相关的图标时，可以认为该第一屏幕中运行的是系统应用。当第一屏幕未处于工作状态(如不显示任何内容)时，可以认为该第一屏幕中未运行任何应用。第二应用标识同理，此处不再赘述。
在一种实现方式中，终端设备开启单屏功能的情况下，工作屏幕由第一屏幕切换为第二屏幕(即第一应用标识由有变为无)，或者，工作屏幕由第二屏幕切换为第一屏幕(即 第一应用标识由无变为有)，可以使得终端设备的屏幕显示参数满足声音调整条件。终端设备在关闭该单屏功能之前，在任何情况下，该终端设备中只有第一屏幕或第二屏幕中的一个屏幕处于工作状态，在开启单屏功能时，该终端设备相当于不包括折叠屏。例如，工作屏幕由第一屏幕切换为第二屏幕，且终端设备中的声音输入输出设备组配置于第一屏幕时，若在第二屏幕上运行视频应用，将使得立体声的声场位于第一屏幕，这样会使得终端设备的音频效果较差。因此，在工作屏幕发生变化时，终端设备可以切换所启用的声音配置参数组，以使得采用新启用的声音配置参数组使得立体声的声场位于当前的工作屏幕的中心，从而有利于提高终端设备的智能性以及灵活性。
在一种实现方式中，第一应用标识对应的应用类型发生变化可以包括：第一应用标识对应的应用类型由音频类变为非音频类，或者，第一应用标识对应的应用类型由非音频类变为音频类。
当终端设备所运行应用的应用类型为非音频类时，终端设备对音效的要求较低，因为此时终端设备仅需要输出电话提示音、短信提示音等。当终端设备所运行应用的应用类型为音频类时，终端设备对音效的要求较高。例如，播放电影时需要较好的音效以提高用户的沉浸感。需要说明的是，使用使得音效较好的声音配置参数时，终端设备的资源消耗较高；使用使得音效较差的声音配置参数时，终端设备的资源消耗较低。因此，当第一屏幕所运行应用的应用类型(即第一应用标识对应的应用类型)由非音频类变为音频类时，终端设备可以切换所启用的声音配置参数组，以使得采用新启用的声音配置参数组使得终端设备的音效较好，有利于提高用户体验。当第一应用标识对应的应用类型由音频类变为非音频类时，终端设备可以切换所启用的声音配置参数组，以使得采用新启用的声音配置参数组终端设备的音效适当降低，这样有利于节省资源。
第二应用标识对应的应用类型发生变化的情况与第一应用标识对应的应用类型发生变化的情况类似，此处不再赘述。需要说明的是，非音频类的应用可以是本身即不具备声音采集功能也不具备声音播放功能，或者，非音频类应用可以是终端设备未对其授予声音采集功能和声音播放功能权限的应用。
对于第6种情况：在第一应用标识和第二应用标识不同，且该第一应用标识和该第二应用标识对应的应用类型均为音频类的情况下，用户焦点所在屏幕的标识发生变化。例如，第一屏幕中运行视频应用a，第二屏幕中运行视频应用b，且视频应用a和视频应用b的应用类型均为音频类时，若用户焦点所在屏幕的标识由第一屏幕的标识变为第二屏幕的标识，则可以表明用户当前较为关注第二屏幕中显示的内容。终端设备可以切换所启用的声音配置参数组，以使得采用新启用的声音配置参数组可以更好地匹配当前应用场景。例如，终端设备切换所启用的声音配置参数组之前，该终端设备通过所启用的声音配置参数组可以使得立体声的声场位于第一屏幕的中心。终端设备切换所启用的声音配置参数组之后，该终端设备通过新启用的声音配置参数组可以使得立体声的声场位于第二屏幕的中心。通过这种方式，可以灵活地调节音频效果，提高终端设备的智能性、灵活性。
在一种实现方式中，当终端设备确定用户焦点所在屏幕为第二屏幕时，终端设备可以输出(如播放)该第二屏幕中运行的应用(即视频应用b)的声音数据，并使得输出该声音数据时立体声的声场位于第二屏幕的中心。同时，可以暂停运行第一屏幕中运行的应用 (即视频应用a)，或者，以不同于视频应用b的声音数据的输出方式输出视频应用a的声音数据。例如，终端设备以外放的形式输出视频应用b的声音数据时，可以静音输出视频应用a的声音数据，或者，通过耳机输出视频应用a的声音数据。通过这种方式，可以避免两个视频应用的声音数据相互干扰。
在本申请实施例中，终端设备可以设置多种类型的屏幕显示参数，例如，屏幕模式，该终端设备中运行的音频类应用的播放模式，该第一屏幕和该第二屏幕之间的折叠角度，该第一屏幕上显示的内容对应的第一应用标识，该第二屏幕上显示的内容对应的第二应用标识或用户焦点所在屏幕的标识。在检测到终端设备的屏幕模式发生变化的情况下，终端设备可以将当前的屏幕模式作为当前的屏幕显示参数。在检测到第一屏幕和该第二屏幕之间的折叠角度发生变化的情况下，终端设备可以将当前的折叠角度作为当前的屏幕显示参数。在检测到第一应用标识对应的应用的类型发生变化的情况下，终端设备可以将当前的第一应用标识作为当前的屏幕显示参数。在第一应用标识和第二应用标识不同，且该第一应用标识和该第二应用标识对应的应用的类型均为音频类的情况下，检测到用户焦点所在屏幕的标识发生变化的情况下，终端设备可以将当前的用户焦点所在屏幕的标识作为当前的屏幕显示参数。
在本申请实施例中，屏幕显示参数满足声音调整条件可以包括上述情况中的一种或多种，在检测到屏幕显示参数满足声音调整条件的情况下，切换终端设备所启用的声音配置参数组，可以灵活地调节音频效果，从而可以更好地匹配不同的应用场景，并有利于提高终端设备的智能性、灵活性。
需要说明的是，步骤S301的其余执行过程可参见图2中步骤S201的具体描述，此处不再赘述。
步骤S302：终端设备根据折叠角度和声音配置参数组之间的对应关系，将前述多个声音配置参数组中与当前的折叠角度对应的声音配置参数组作为第一声音配置参数组。
具体的，终端设备获取当前的屏幕显示参数(如当前的折叠角度)之后，可以根据当前的屏幕显示参数从前述多个声音配置参数组中确定第一声音配置参数组。终端设备根据当前的屏幕显示参数从前述多个声音配置参数组中确定第一声音配置参数组的具体实施方式可以为：根据折叠角度和声音配置参数组之间的对应关系，将前述多个声音配置参数组中与当前的折叠角度对应的声音配置参数组作为第一声音配置参数组。通过这种方式，可以随着折叠角度的变化，动态适配声音配置参数组，并切换终端设备所启用的声音配置参数组。通过这种方式，可以灵活地调节音频效果，提高终端设备的智能性、灵活性，并有利于使用户获得更好的音频体验。在一种实现方式中，一个声音配置参数组可以对应一个或多个角度。
步骤S303：终端设备将第二声音配置参数组更新为该第一声音配置参数组，该第二声音配置参数组为该终端设备当前启用的声音配置参数组。
需要说明的是，步骤S302～步骤S303的执行过程可参见图2中步骤S202～步骤S203的具体描述，此处不再赘述。
通过实施本申请实施例，在检测到第一屏幕和该第二屏幕之间的折叠角度发生变化的情况下，通过切换终端设备所启用的声音配置参数组，可以灵活地调节音频效果，提高终 端设备的智能性、灵活性。

需要说明的是，步骤S401的执行过程可参见图3a中步骤S301的具体描述，此处不再赘述。
步骤S402：终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕。
具体的，终端设备根据当前的屏幕显示参数从前述多个声音配置参数组中确定第一声音配置参数组的具体实施方式可以为：根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕；并根据该第三屏幕从前述多个声音配置参数组中确定第一声音配置参数组。
其中，第三屏幕可以为终端设备中处于工作模式下的屏幕，也可以为运行有音频类应用的屏幕，也可以为用户较为关注的屏幕。第三屏幕可以包括第一屏幕和第二屏幕中的一个或两个屏幕。确定第三屏幕之后，可以根据第三屏幕确定第一声音配置参数组。终端设备启用第一声音配置参数组之后，可以使得终端设备的音效与第三屏幕相匹配。终端设备的音效与第三屏幕相匹配可以表示：播放声音时立体声的声场位于第三屏幕的中心。
在一种实现方式中，当前的屏幕显示参数可以包括但不限于：当前的第一应用标识，当前的第二应用标识或当前的用户焦点所在屏幕的标识中的一种或多种。其中，当前的第一应用标识为检测到终端的屏幕显示参数满足声音调整条件时，第一屏幕上运行的应用的标识。当前的第二应用标识为检测到终端的屏幕显示参数满足声音调整条件时，第二屏幕上运行的应用的标识。
终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕的具体实施方式可以为：若当前的第一应用标识为应用标识a，且当前的第二应用标识为无(即第二屏幕并未显示任何内容)，则将该第一屏幕作为第三屏幕。此时，该第三屏幕为终端设备中处于工作模式下的屏幕。
在一种实现方式中，终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕的具体实施方式可以为：若当前的第一应用标识为应用标识a，当前的第二应用标识为应用标识b，且应用标识a指示的应用处于活跃状态，则将该第一屏幕作为第三屏幕。终端设备中处于活跃状态的应用的数量为一个，处于活跃状态的应用可以为用户当前使用的应用，或者，用户最近使用的应用。即在此情况下，第三屏幕为运行处于活跃状态下的应用的屏幕。
在一种实现方式中，终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕的具体实施方式可以为：若当前的第一应用标识对应的应用类型为前述音频类，且当前的第二应用标识对应的应用类型为前述非音频类，则将该第一屏幕作为第三屏幕。换言之，终端设备可以将运行有音频类应用的屏幕作为第三屏幕。此时，第三屏幕为运行有音频类应用的屏幕。
在一种实现方式中，终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕的具体实施方式可以为：若当前的第一应用标识和当前的第二应用标识对应的应用类型均为音频类，且当前的第一应用标识和当前的第二应用标识相同，则将第一屏幕和第二屏幕作为第三屏幕。当前的第一应用标识和当前的第二应用标识对应的应用类型均为音频类，且当前的第一应用标识和当前的第二应用标识相同的情况下，可以表明该终端设备处于非折叠状态，且以全屏模式输出一个应用的数据。例如，图3d中终端设备以全屏模式输出视频应用中猫和老鼠视频的数据。此时，第三屏幕为运行有音频类应用的屏幕。
在一种实现方式中，终端设备根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕的具体实施方式可以为：若当前的第一应用标识和当前的第二应用标识对应的应用类型均为音频类，且当前的第一应用标识和当前的第二应用标识不同，则将当前的用户焦点所在屏幕的标识指示的屏幕作为第三屏幕，当前的用户焦点所在屏幕的标识指示的屏幕为第一屏幕或第二屏幕。例如，第一屏幕中运行视频应用a，第二屏幕中运行视频应用b，且视频应用a的应用类型和视频应用b的应用类型均为音频类时，若用户焦点所在屏幕的标识由第一屏幕的标识变为第二屏幕的标识，则可以将第二屏幕作为第三屏幕。此时，该第三屏幕为用户较为关注的屏幕。
步骤S403：终端设备根据该第三屏幕从前述多个声音配置参数组中确定第一声音配置参数组。
具体的，终端设备可以根据屏幕与声音配置参数组之间的对应关系，将与该第三屏幕对应的声音配置参数组作为第一声音输入输出设备组。当终端设备包括3个声音配置参数组时，屏幕与声音配置参数组之间的对应关系可以如表3所示。采用声音配置参数组1对终端设备进行配置，可以使得终端设备输出声音时立体声的声场位于第一屏幕的中心。采用声音配置参数组2对终端设备进行配置，可以使得终端设备输出声音时立体声的声场位于第二屏幕的中心。采用声音配置参数组3对终端设备进行配置，可以使得终端设备输出声音时立体声的声场位于第一屏幕和第二屏幕组成的大屏幕的中心。
表3 屏幕与声音配置参数组之间的对应关系
屏幕 声音配置参数组
第一屏幕 声音配置参数组1
第二屏幕 声音配置参数组2
第一屏幕+第二屏幕 声音配置参数组3
在一种实现方式中，终端设备可以包括一个或多个声音输入输出设备组，多个声音输入输出设备组可以分布于一个或多个屏幕上。在一种实现方式中，第一屏幕(或者第二屏幕)上可以配置一个或多个声音输入输出设备组。本申请实施例以第一屏幕和第二屏幕上均配置一个声音输入输出设备组为例进行说明。
多个声音输入输出设备组中的各个声音输入输出设备组对应的声音配置参数组可以包括单屏声音配置参数组和全屏声音配置参数组。采用单屏声音配置参数组对相应的声音输入输出设备组进行配置，可以使得终端设备输出声音时立体声的声场位于该声音输入输出设备组所在屏幕的中心。采用全屏声音配置参数组对相应的声音输入输出设备组进行配置，可以使得终端设备输出声音时立体声的声场位于第一屏幕和第二屏幕组成的大屏幕的中心。
终端设备根据该第三屏幕从前述多个声音配置参数组中确定第一声音配置参数组的具体实施方式可以为：根据屏幕与声音输入输出设备组之间的对应关系，将第三屏幕对应的声音输入输出设备组作为第一声音输入输出设备组；若该第三屏幕包括第一屏幕或第二屏幕，则将该第一声音输入输出设备组对应的单屏声音配置参数组作为第一声音配置参数组；若该第三屏幕包括第一屏幕和第二屏幕，则将每个第一声音输入输出设备组对应的全屏声音配置参数组均作为第一声音配置参数组。
在本申请实施例中，第一屏幕与该第一屏幕上配置的声音输入输出设备组可以具有对应关系，第二屏幕与该第二屏幕上配置的声音输入输出设备组可以具有对应关系。第三屏幕对应的声音输入输出设备组(即第一声音输入输出设备组)可以为检测到屏幕显示参数满足声音调整条件之后，终端设备所启用的声音输入输出设备组。在检测到屏幕显示参数满足声音调整条件时，终端设备所启用的声音输入输出设备组可以为第二声音输入输出设备组，即第二声音输入输出设备组为终端设备当前启用的声音输入输出设备组。确定第一声音输入输出设备组之后，终端设备可以将第二声音输入输出设备组更新为第一声音输入输出设备组。
在本申请实施例中，不同声音输入输出设备组对应的声音配置参数组可以不同。以图4b所示的屏幕和声音输入输出设备组在终端设备中的对应关系图为例，图4b中，终端设备100包括第一屏幕104和第二屏幕105，通过转动转轴106可以改变第一屏幕104和第二屏幕105之间的折叠角度。第一屏幕104对应声音输入输出设备组a，声音输入输出设备组a由喇叭101、听筒102和麦克风103组成；第二屏幕105对应声音输入输出设备组b，声音输入输出设备组b由喇叭108、听筒109和麦克风110组成。当声音输入输出设备组a对应单屏声音配置参数组a，声音输入输出设备组b对应单屏声音配置参数组b时。通过单屏声音配置参数组a对声音输入输出设备组a进行配置，可以使得终端设备输出声音时立体声的声场位于第一屏幕的中心。通过单屏声音配置参数组b对声音输入输出设备组b进行配置，可以使得终端设备输出声音时立体声的声场位于第二屏幕的中心。
在一种实现方式中，终端设备也可以通过单屏声音配置参数组c对声音输入输出设备组b进行配置，以使得终端设备输出声音时立体声的声场位于第一屏幕104的中心。由图4b可知，第一屏幕104的中心与声音输入输出设备组b之间的距离大于第一屏幕104的中 心与声音输入输出设备组a之间的距离。因此，为使得立体声的声场位于第一屏幕的中心时，相较于通过单屏声音配置参数组a对声音输入输出设备组a进行配置，通过单屏声音配置参数组c对声音输入输出设备组b进行配置所消耗的资源更多。所以终端设备可以启用声音输入输出设备组a，即将声音输入输出设备组a作为第一声音输入输出设备组，进而从第一声音输入输出设备组对应的声音配置参数组中确定第一声音配置参数组。
第三屏幕包括第一屏幕和第二屏幕中的一个屏幕时，可以表明终端设备中处于工作模式下的屏幕数量为一个，或者，运行有音频类应用的屏幕数量为一个，或者，用户较为关注的屏幕数量为一个。在此情况下，使用单屏声音配置参数组对终端设备进行配置所产生的音效即可满足用户需求。可以理解的是，终端设备以全屏模式输出某应用的数据时，该应用对于声音功能的要求较高，在该场景下终端设备可以加载使音效较好的声音配置参数组。在本申请实施例中，采用单屏声音配置参数组对声音输入输出设备组进行配置之后，在输出声音数据或者采集声音数据时，终端设备消耗的资源低于采用全屏声音配置参数组对该同一声音输入输出设备组进行配置之后，在输出声音数据或者采集声音数据时，终端设备消耗的资源。因此，第三屏幕包括第一屏幕和第二屏幕中的一个屏幕时，将第一声音输入输出设备组对应的单屏声音配置参数组作为第一声音配置参数组，有利于在确保终端设备的音效的前提下降低终端设备的资源消耗。
第三屏幕包括第一屏幕和第二屏幕时，可以表明终端设备中处于工作模式下的屏幕数量为两个，或者，第一屏幕和第二屏幕共同运行一个音频类应用。此时，终端设备中运行的应用占用了较大的屏幕面积，可以认为用户当前较为关注第一屏幕和第二屏幕中运行的音频类应用的数据。在此情况下，终端设备可以启用第一屏幕和第二屏幕上的所有声音输入输出设备组，并将所有声音输入输出设备组中的各个声音输入输出设备组对应的全屏声音配置参数组均作为第一声音配置参数组，进而通过各个声音输入输出设备组对应的全屏声音配置参数组对该声音输入输出设备组进行配置。通过这种方式，可以灵活地调节音频效果，并有利于最优化终端设备的音频效果，从而有利于增强用户的沉浸感，并有利于提高终端设备的智能性、灵活性。
以图4c所示的终端设备中声音输入输出设备组的使用情况的示意图为例。在图4c中，终端设备100包括第一屏幕104和第二屏幕105，第一屏幕104和第二屏幕105之间的折叠角度为30°，通过转动转轴106可以改变折叠角度。第一屏幕104包括一个声音输入输出设备组1，声音输入输出设备组1包括喇叭101、听筒102和麦克风103；第二屏幕105包括一个声音输入输出设备组2，声音输入输出设备组2包括喇叭108、听筒109和麦克风110。若确定出的第三屏幕包括第一屏幕104和第二屏幕105，则可以将声音输入输出设备组1和声音输入输出设备组2均确定为第一声音输入输出设备组，即终端设备可以启用声音输入输出设备组1和声音输入输出设备组2以输出猫和老鼠视频的声音数据。图4c中声音输入输出设备组以格纹填充时，表示该声音输入输出设备组被终端设备所启用。
在一种实现方式中，确定第一声音输入输出设备组之后，若第三屏幕包括第一屏幕和第二屏幕，且第一屏幕和第二屏幕之间的折叠角度为0°，则终端设备可以将每个第一声音输入输出设备组对应的全屏声音配置参数组均作为第一声音配置参数组。
图4c中第一屏幕和第二屏幕之间的折叠角度变为0°后得到的终端设备的示意图可以 如图4d所示。在本申请实施例中，第一屏幕和第二屏幕之间的折叠角度为0°时，终端设备中的各个声音输入输出设备组通过对应的全屏声音配置参数组进行配置之后得到的音频效果优于折叠角度为除0°以外的其他角度时，终端设备中的各个声音输入输出设备组通过对应的全屏声音配置参数组进行配置之后得到的音频效果。参见图4c以及图4d可以想到，当图4c和图4d中的喇叭101、喇叭108通过相同的声音配置参数进行配置，且图4c和图4d中的听筒102、听筒109通过相同的声音配置参数进行配置时，图4d中终端设备的音频播放效果优于图4c中终端设备的音频播放效果。这是因为图4c中折叠角度为30°时，若用户正对第一屏幕，则该用户可以最大程度接收第一屏幕上的喇叭101和听筒102播放的声音，但不能以最大程度接收第二屏幕上的喇叭108和听筒109播放的声音。在图4d中，由于折叠角度为0°，若用户正对第一屏幕，则用户可以最大程度接收第一屏幕上的喇叭101和听筒102播放的声音以及以最大程度接收第二屏幕上的喇叭108和听筒109播放的声音。所以在第一屏幕和第二屏幕之间的折叠角度为0°的情况下，使用全屏声音配置参数组对相应的声音输入输出设备组进行配置，有利于最大程度地提高终端设备的音频效果。
需要说明的是，在本申请实施例中，声音输出的相关步骤与采集声音的相关步骤类似，根据声音输出的相关步骤可以确定采集声音的相关步骤，本申请实施例不再赘述。
步骤S404：终端设备将第二声音配置参数组更新为该第一声音配置参数组，该第二声音配置参数组为该终端设备当前启用的声音配置参数组。
在本申请实施例中，若第一声音配置参数组包括声音配置参数组1和声音配置参数组2；第一声音输入输出设备组包括声音输入输出设备组1和第一声音输入输出设备组2。并且，声音配置参数组1为声音输入输出设备组1对应的单屏声音配置参数组或者全屏声音配置参数组，声音配置参数组2为声音输入输出设备组2对应的单屏声音配置参数组或者全屏声音配置参数组，则终端设备可以调用声音配置参数组1对声音输入输出设备组1进行配置，并调用声音配置参数组2对声音输入输出设备组2进行配置。
需要说明的是，步骤S404的执行过程可参见图3a中步骤S303的具体描述，此处不再赘述。
通过实施本申请实施例，在检测到终端设备的屏幕显示参数满足声音调整条件的情况下，可以根据当前的屏幕显示参数从第一屏幕和第二屏幕中确定第三屏幕，并根据该第三屏幕从终端设备包括的多个声音配置参数组中确定第一声音配置参数组。其中，第三屏幕可以为终端设备中处于工作模式下的屏幕，也可以为运行有音频类应用的屏幕，也可以为用户较为关注的屏幕。通过这种方式，可以使得终端设备的音效与第三屏幕相匹配。
