具体实施方式
本申请下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。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；文本中的“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。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请以下实施例中的术语“用户界面(user interface，UI)”，是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。用户界面是通过java、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在电子设备上经过解析，渲染，最终呈现为用户可以识别的内容。用户界面常用的表现形式是图形用户界面(graphic user interface，GUI)，是指采用图形方式显示的与计算机操作相关的用户界面。它可以是在电子设备的显示屏中显示的文本、图标、按钮、菜单、选项卡、文本框、对话框、状态栏、导航栏、Widget等可视的界面元素。
本申请实施例提供了一种处理方法。电子设备100包括应用处理器和微控制单元。其中，微控制单元的运行时功耗低于应用处理器的运行时功耗。电子设备100可以在播放第一音频时，判断微控制单元是否支持播放该第一音频，并在判定出微控制单元支持播放该第一音频时，通过微控制单元播放第一音频的数据。电子设备100可以在判定出微控制单元不支持播放第一音频时，通过应用处理器解码该第一音频，得到第一数据。应用处理器可以将第一数据发送至微控制单元。微控制单元控制扬声器播放该第一数据。这样，电子设备100使用微控制单元播放音频，由于微控制单元的功耗低于应用处理器的功耗，可以节约电子设备100播放音频的功耗。并且，应用处理器可以在微控制单元控制扬声器播放声音时，切换为休眠状态，进一步节约功耗。
其中，应用处理器处于休眠状态(又称为待机状态、低功耗状态)时，输入应用处理器的电流较小，应用处理器的功耗较低；应用处理器处于非休眠状态(又称为高功耗状态)时，输入应用处理器的电流较大，应用处理器的功耗较高。可以理解的是，处于非休眠状态的应用处理器的功耗高于处于休眠状态的应用处理器的功耗，处于非休眠状态的应用处理器的输入电流大于处于休眠状态的应用处理器的输入电流。
接下来介绍本申请实施例提供的一种电子设备100。

需要说明的是，微控制单元102也可以包括上述一个或多个接口。可以理解的是，本发明实施例示意的各模块间的接口连接关系，只是示意性说明，并不构成对电子设备100的结构限定。在本申请另一些实施例中，电子设备100也可以采用上述实施例中不同的接口连接方式，或多种接口连接方式的组合。
具体实现中，应用处理器101可以集成有中央处理器(central process unit，CPU)、图形处理器(graphics processing unit，GPU)、视频编解码器、内存子系统等多个模块。在一些示例中，应用处理器101可以为Arm-coretex-A核处理器，其时钟频率(又称为工作频率)超过1GHz，通常包括4个及以上的处理核心。应用处理器101的随机访问存储器的内存容量约2GB及以上。应用处理器101可以用于运行Linux、Android、Windows、鸿蒙等操作系统。应用处理器101的运行时电流通常在100mAh，待机电流通常在4mAh。在本 申请实施例中，应用处理器101可以用于解码音频，得到待播放的音频的数据。其中，应用处理器101支持的解码多种音频格式的音频，例如，动态影像专家压缩标准音频层面3(moving picture experts group audio layer III，MP3)、高级音频编码(advanced audio coding，ACC)、自适应多速率(adaptive multi-rate，AMR)脉冲编码调制(pulse code modulation，PCM)、Ogg(oggvobis)、第三代合作伙伴计划(the 3rd generation partner project，3GP)、高级串流格式(advanced streaming format，ASF)、AV1、传输流(transport stream，TS)、多媒体容器文件格式(mkv file format，MKV)、MP4(mpeg-4part 14)、微软媒体音频(windows media audio，WMA)、波形声音文件(WAV)、M4A、音频数据传输流(audio data transport stream，ADTS)、SLK等。需要说明的是，应用处理器101不能通过系统提供的服务解码SLK音频格式的音频，应用处理器101可以基于应用提供的组件解码SLK音频格式的音频。

在一些示例中，音乐应用提供权限受限的音频。应用处理器101可以使用音乐应用提供的参数，解码该具有权限受限的音频，得到音频数据。微控制单元102不支持解码权限受限的音频，因此，若某个音频权限受限，无论该音频为任意的音频格式，微控制单元102也不支持解码该音频。
需要说明的是，应用处理器101和微控制单元102支持的音频格式仅为示例，本申请实施例对此不作限定。

在本申请一些实施例中，电子设备100为智能手表，该电子设备100还可以包括有表带和表盘。表盘 可以包括有上述显示屏，以用于显示图像、视频、控件、文字信息等等。表带可以用于将电子设备100固定在人体四肢部位以便于穿戴。
在一种可能的实现方式中，电子设备100包括应用处理器和微控制单元。电子设备100的处于非休眠状态的应用处理器可以在接收到播放第一音频的输入后，向微控制单元发送用于查询微控制单元是否支持播放第一音频的查询请求。若应用处理器收到微控制单元回复的结果为支持播放第一音频，可以通知微控制单元播放第一音频，并且在微控制单元播放第一音频时，切换为休眠状态。若应用处理器收到微控制单元回复的结果为不支持播放第一音频，可以针对第一音频执行解码操作，得到第一数据。应用处理器可以将第一数据发送至微控制单元，微控制单元可以控制扬声器播放该第一数据。这样，通过功耗较低的电子设备100的微控制单元控制扬声器播放音频，使得功耗较高的应用处理器不必执行音频播放操作，节约设备功耗。

在另一些实施例中，应用处理器可以在发送第一音频时，向微控制单元发送播放指示。微控制单元可以在收到播放指示和第一音频后，解码并播放第一音频。微控制单元还可以在接收到第一音频和播放指示后，向应用处理器发送用于指示微控制单元正在播放第一音频的播放状态信息。应用处理器可以在收到该播放状态信息后，从非休眠状态切换至休眠状态。
需要说明的是，电子设备100在播放第一音频时，若电子设备100处于连续播放音频的状态(例如，顺序播放状态或随机播放状态)时，电子设备100可以在播放完第一音频后，继续播放第一音频所在的播放列表中的其他音频。例如，电子设备100可以在控制扬声器播放该第一数据后，继续播放第三音频，第三音频与第一音频不同，第三音频与第一音频属于同一个播放列表。

接下来结合图1所示的电子设备100的硬件结构，示例性的介绍一种应用处理器和微控制单元的软件架构。
示例性的，如图3所示，分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，操作系统包括但不限于应用层(又称为应用程序层)，应用程序框架层，系统库以及内核层。
其中，应用层可以包括一系列应用程序包。其中，应用处理器101的应用层可以包括但不限于音乐应用301，通话应用302，桌面应用303等应用程序。其中，音乐应用301可以用于播放第一音频。通话应用302可以用于接听通话。桌面应用303可以用于显示包括应用程序的图标的桌面。
应用程序框架层可以为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架，应用程序框架层包括一些预先定义的函数。
其中，应用处理器101的应用程序框架层可以包括但不限于协同播放模块311、解码服务模块312、焦点管理模块313、焦点代理模块314、音量同步模块315、音量调节服务模块316、双核通信模块317、电源管理模块318等等。
其中，协同播放模块311可以用于将音乐应用301的音频发送至解码服务模块312。
解码服务模块312可以用于解码音频，得到音频的数据。
焦点管理模块313可以用于分配、管理扬声器。应用程序可以从焦点管理模块313获取扬声器的焦点，应用程序可以在获取到扬声器的焦点后，使用扬声器播放音频。焦点管理模块313在某个应用程序占用扬声器焦点时，若焦点管理模块313收到另一个应用程序占用扬声器的请求，通知该应用程序失去扬声器焦 点，并且将扬声器焦点分配给发送请求的另一个应用程序。这样，应用程序可以在收到丢失扬声器焦点的通知后，暂停播放音频。
焦点代理模块314可以用于代表微控制单元102，当微控制单元102占用扬声器时，可以通知焦点代理模块314。焦点代理模块314可以向焦点管理模块313发送占用扬声器的请求，让焦点管理模块313记录焦点代理模块314正在使用扬声器。焦点管理模块313可以在收到其他应用程序(例如，电话应用)占用扬声器的请求时，通知焦点代理模块314。焦点代理模块314可以通知微控制单元102，微控制单元102可以在接收到焦点代理模块314的通知后，执行暂停播放音频的操作。这样，由于应用处理器101的焦点管理模块313只负责应用处理器的焦点管理。微控制单元102占用扬声器时，应用处理器101的焦点管理模块313无法通知微控制单元102。因此，以焦点代理模块314代表微控制单元，可以在应用处理器101的应用程序占用焦点时，通过焦点代理模块314通知微控制单元101，便于微控制单元102执行暂停播放音频的操作。
例如，当微控制单元102占用扬声器时，即，焦点管理模块313记录焦点代理模块314占用扬声器时，若焦点管理模块313收到通话应用的占用扬声器的请求，焦点管理模块313可以通知焦点代理模块314停止占用扬声器，并且通知电话应用使用扬声器。通话应用可以通过扬声器播放音频(例如，来电铃声)。焦点代理模块314可以通知微控制单元102停止使用扬声器。微控制单元102收到焦点代理模块314的通知后，可以记录播放音频的播放进度。当应用处理器101再次收到用户播放音频的输入后，电子设备100可以从记录的播放进度处继续播放该音频。这样，微控制单元102可以在扬声器被其他应用或模块占用时，保存播放音频播放的进度，便于下次播放该音频时存储的播放进度处继续播放该音频。
音量同步模块315可以用于在收到音量调节服务模块316发送的音量值后，将该音量值同步到微控制单元102。具体的，音量同步模块315可以将音量值发送给微控制单元102的音量调节服务模块324，用于调整微控制单元102的音量。
音量调节服务模块316可以用于基于用户的音量调节操作，改变电子设备100的应用处理器101的音量。音量调节服务模块315可以将改变后的音量发送给音量同步模块315。
双核通信模块317可以用于应用处理器101和微控制单元102进行数据的传输。例如，将应用处理器101提供的第一音频的第一数据发送给微控制单元102。

具体的，应用处理器(例如，图1所示的应用处理器101)运行应用程序时，可以从应用处理器的存储器中取出应用程序的程序代码。其中，程序代码的编程语言为应用处理器指示的编程语言(例如，Java/C++)。应用处理器可以通过应用处理器的编译器将程序代码编译为计算机指令，并执行这些计算机指令。这些计算机指令中的每一条指令都属于应用处理器的指令集。
同理，微控制单元(例如，图1所示的微控制单元102)运行应用程时，可以从微控制单元的存储器中取出应用程序的程序代码。其中，程序代码的编程语言为微控制单元指示的编程语言(例如，C/C++)。微控制单元可以通过微控制单元的编译器将程序代码编译为计算机指令，并执行这些计算机指令。这些计算机指令中的每一条指令都属于微控制单元的指令集。
需要说明的是，由于微控制单元和应用处理器的指令集不同，在一些情况下，编程语言也不同。若应用处理器和微控制单元安装有同一个应用程序，应用处理器中存储的应用程序的代码和微控制单元中存储的该应用程序的代码不同。
还需要说明的是，由于应用处理器的指令集与微控制单元的指令集不同，应用程序的代码也不同。应用处理器不能运行微控制单元的应用程序，微控制单元也不能运行应用处理器的应用程序。
其中，由应用处理器运行的应用程序可以称为部署在应用处理器上的应用程序，或者，也可以称为应用处理器的应用程序。由微控制单元运行的应用程序可以称为部署在微控制单元上的应用程序，或者，也可以称为微控制单元的应用程序。
需要说明的是，由于应用处理器和微控制单元的运行主频，内存容量不同，例如，该运行主频，内存容量的差异可以参见图1所示实施例，在此不再赘述。应用处理器可以用于运行复杂度高的计算型业务和网络业务等。例如，应用处理器可以运行桌面、通话、畅连语音、房颤早搏本地筛查、地图等应用程序。微控制单元102可以用于运行简单计算型业务。例如，微控制单元102可以用于运行例如心率检测、压力检测、日常活动、音乐等应用程序。其中，应用处理器运行的应用的代码的编程语言为应用处理器指示的编程语言。微控制单元运行的应用的代码的编程语言为微控制单元指示的编程语言。

如上表1所示，该表中示出了部分应用程序和其对应的处理器标识。其中，锻炼应用、信息应用和音乐应用的处理器标识为微控制单元。桌面应用、通话应用的处理器标识为应用处理器。也就是说，电子设备100显示桌面时，由应用处理器运行该桌面应用，控制显示屏显示桌面。电子设备100的应用处理器可以在接收到打开某个应用的输入时，判断该应用的处理器标识，决定是否通知微控制单元运行被打开的应用。例如，当电子设备100的应用处理器在控制显示屏显示桌面时，接收到打开音乐应用的输入时，应用处理器基于音乐应用的处理器标识，确定出由微控制单元运行音乐应用，应用处理器可以给微控制单元发送通知消息，该通知消息可以携带音乐应用的标识(例如，应用名称)，微控制单元可以在接收到应用处理器的通知消息后，运行该音乐应用，例如，控制显示屏显示音乐应用的界面。再例如，当电子设备100的应用处理器在控制显示屏显示桌面时，接收到打开通话应用的输入时，应用处理器基于通话应用的处理器标识，确定出由应用处理器运行通话应用，应用处理器运行通话应用，例如，控制显示屏显示通话应用的界面。
在另一种可能的实现方式中，电子设备100包括应用处理器和微控制单元。电子设备100的微控制单元部署有音乐应用。微控制单元显示音乐应用的界面时，接收到播放音乐应用的第一音频的输入。微控制单元可以响应于该输入，判断微控制单元是否支持播放该第一音频。微控制单元可以在判定出微控制单元不支持播放该音频时，通知应用处理器处理该第一音频，得到第一数据。微控制单元可以获取应用处理器的第一数据，并控制扬声器播放该第一数据。微控制单元可以在判定出微控制单元支持播放该第一音频时，通过微控制单元播放该第一音频。
这样，电子设备100使用微控制单元运行音乐应用、播放第一音频，由于微控制单元的功耗低于应用处理器的功耗，可以节约电子设备100播放音频的功耗。并且，应用处理器可以在微控制单元控制扬声器播放声音时，切换为休眠状态，进一步节约功耗。

在另一些示例中，不限于上述步骤S701-步骤S705，处于未休眠状态的应用处理器可以响应于用户用于播放第一音频的语音指令，向微控制单元发送播放请求，播放请求用于指示微控制单元播放第一音频，微控制单元在接收到播放请求后，可以执行步骤S706。应用处理器在接收到用户的语音指令之前，控制显示屏显示的界面可以不为音乐应用的界面。也就是说，应用处理器在控制显示屏显示任意界面时，都可以响应于用户用于播放第一音频的语音指令，向微控制单元发送播放请求。可选的，应用处理器在向微控制单元发送播放请求后，可以从未休眠状态切换为休眠状态。
或者，电子设备100显示文件管理应用的界面时，该界面包括存储的一个或多个音频对应的音频选项，该一个或多个音频包括第一音频，该一个或多个音频选项包括第一音频选项。电子设备100可以接收用户针对第一音频选项的输入后，执行步骤S706。

需要说明的是，不限于上述先判断微控制单元是否存储有第一音频的标识对应的第二音频，再在微控制单元未存储第二音频时判断微控制单元不支持解码第一音频的音频格式的顺序。微控制单元可以先判断微控制单元是否支持解码第一音频的音频格式，再在微控制单元不支持解码第一音频的音频格式时，判断微控制单元是否存储有第一音频的标识对应的第二音频。或者，微控制单元可以同时判断微控制单元是否支持解码第一音频的音频格式以及微控制单元是否存储有第一音频的标识对应的第二音频，本申请实施例对此不作限定。

具体的，上述各个步骤的具体描述可以参见图7所示实施例，在此不再赘述。
在一种可能的实现方式中，在微控制单元使用扬声器的过程中，若应用处理器接收到指定应用使用扬声器的请求时，可以通知微控制单元停止使用扬声器，并将扬声器分配给指定应用。其中，指定应用可以包括但不限于通话类应用，例如通话应用302。需要说明的是，在本申请实施例中，指定应用可以代指没有通过微控制单元进行音频播放的应用程序。
在一种可能的实现方式中，应用处理器包括焦点代理模块，当电子设备100的微控制单元使用扬声器时，应用处理器的焦点代理模块可以从焦点管理模块获取扬声器的焦点。焦点管理模块可以在扬声器焦点被其他应用程序占用时，通知焦点代理模块。焦点代理模块可以通知微控制单元，微控制单元可以在接收到焦点代理模块的通知后，执行暂停播放音频的操作。这样，由于应用处理器的焦点管理模块只负责应用处理器的焦点管理。微控制单元占用扬声器时，应用处理器的焦点管理模块无法通知微控制单元。因此，以焦点代理模块代表微控制单元，可以在应用处理器的应用程序占用焦点时，通过焦点代理模块通知微控制单元，便于微控制单元执行暂停播放音频的操作。
结合图8所示的软件架构图，示例性的介绍本申请实施例提供的扬声器调度方法。如图10所示，该方法包括：
S1001.音乐应用801向焦点代理模块814发送占用消息81，表示微控制单元102正在使用扬声器。
音乐应用801可以在微控制单元102播放第一音频时，向焦点代理模块814发送占用消息81。
S1002.焦点代理模块814向焦点管理模块813发送占用消息82，表示焦点代理模块814占用扬声器。
S1003.焦点管理模块813设置扬声器被焦点代理模块814占用。
S1004.通话应用802向焦点管理模块813发送占用请求83，表示通话应用802占用扬声器。
可以理解的是，通话应用802可以在获取到扬声器焦点后，使用扬声器播放来电提示音。
S1005.焦点管理模块813设置扬声器被通话应用802占用。
在一些实施例中，焦点管理模块813可以基于应用的优先权，判断是否给该应用分配扬声器。示例性的，当焦点管理模块813设置扬声器被应用A占用时，收到来自应用B的占用请求，焦点管理模块813可以判断应用B的优先权是否高于应用A的优先权。当焦点管理模块813判定出应用B的优先权高于应用A的优先权时，通知应用A停止占用扬声器，并将扬声器分配给应用B。当焦点管理模块813判定出应用B的优先权低于应用A的优先权时，不改变占用扬声器的应用。此时，应用B无法获取到扬声器。
S1006.焦点管理模块813向焦点代理模块814发送停止占用消息84，表示扬声器被其他应用占用。
S1007.焦点代理模块814向音乐应用801发送焦点丢失消息85，表示扬声器被其他应用占用。
S1008.音乐应用801向音频播放驱动827发送停止播放消息86，指示音频驱动模块827停止播放音频。
具体的，上述步骤S1002至步骤S1008的详细描述可以参见图5所示实施例，在此不再赘述。
在一种可能的实现方式中，微控制单元在判定出不支持播放第一音频时，可以通知应用处理器解码并播放第一音频。微控制单元102也可以通过焦点代理模块占用焦点管理模块提供的扬声器焦点。这样，由于音乐应用部署在微控制单元，微控制单元通过应用处理器解码、播放第一音频时，可以使用焦点代理模块占用应用处理器的焦点管理模块的扬声器焦点。当扬声器焦点被应用处理器的其他应用占用后，便于微 控制单元通知应用处理器暂停播放第一音频。
具体的，结合图8所示的软件架构，当音乐应用801接收到用户播放第一音频的输入后，可以通知焦点代理模块814。焦点代理模块814可以获取焦点管理模块813的焦点。当焦点管理模块813的扬声器焦点被其他应用占用后，焦点代理模块814可以通知音乐应用801。具体的，可以参见上述步骤S1002至步骤S1007，在此不再赘述。
当应用处理器101解码并播放第一音频时，应用处理器101的解码服务模块812可以接收音乐应用801提供的第一音频，并解码该第一音频，得到第一数据。解码服务模块812可以将第一数据发送给音频驱动模块802，音频驱动模块802可以控制扬声器播放该第一数据。
音乐应用801可以在收到焦点丢失的通知消息后，通知应用处理器101停止播放第一音频。具体的，音乐应用801可以通知解码服务模块812停止解码，并通知音频驱动模块802停止播放音频。
在一种可能的实现方式中，电子设备100的微控制单元接收到调整音量的输入后，可以调整微控制单元的音量值。电子设备100的微控制单元可以通知应用处理器调整后的音量值，应用处理器可以在接收调整音量的通知后，将应用处理器的音量值调整至与微控制单元的音量值相同。这样，微控制单元在播放音频的过程中，微控制单元检测到音量调节输入，可以通知应用处理器调整后的音量，应用处理器可以使用调整后的音量播放音频，例如，提示音。
结合图8所示的软件架构图，示例性的介绍本申请实施例提供的音量调节方法。
如图11所示，微控制单元102可以通过音量同步模块823，将音量同步到应用处理器101，其中，音量调节方法包括以下步骤：
S1101.音量调节服务模块824接收到调节音量的输入。
S1102.音量调节服务模块824将音量设置为调节后的音量值。
电子设备100的微控制单元102控制显示屏显示音乐应用801的界面。该音乐应用801的界面还包括音量设置图标。电子设备100的微控制单元102可以在接收到针对音量设置图标的输入(例如单击)后，控制显示屏显示音量条。该调节音量的输入可以为针对音量条的滑动输入。
音量调节服务模块824可以基于调节音量的输入，将微控制单元102的音量设置为调节后的音量值。
例如，电子设备100的微控制单元102可以在检测到向左或向下滑动音量条的输入，将该输入发送给音量调节服务模块824，音量调节服务模块824可以根据滑动输入的滑动距离，减小微控制单元102的音量。
电子设备100的微控制单元102可以在检测到向右或向上滑动音量条的输入，将该输入发送给音量调节服务模块824，音量调节服务模块824可以根据滑动输入的滑动距离，增大微控制单元102的音量。
S1103.音量调节服务模块824向音量同步模块823发送音量调节消息91，音量调节消息91携带有调节后的音量值。
音量调节服务模块824可以在调整微控制单元102的音量值后，将携带有调整后的音量值的音量调节消息91发送给音量同步模块823。
S1104.音量同步模块823向音量调节服务模块816发送音量调节消息92，音量调节消息92携带有调节后的音量值。
音量同步模块823收到音量调节消息91后，可以向应用处理器101的音量调节服务模块816发送音量调节消息92，通知音量调节服务模块816调整应用处理器101的音量，使得应用处理器101的音量值和微控制单元102的音量值保持相同。
S1105.音量调节服务模块816将音量设置为调节后的音量值。
应用处理器101的音量调节服务模块816收到音量调节消息92后，可以将音量调节消息92中携带的音量值设置为应用处理器101的音量值。
