为便于理解，下面以Android系统为例，对Android系统中的音频系统架构进行简单说明。
如图1a所示，本实施例提供的音频系统架构主要包括用户空间、内核空间和硬件系统。用户空间包括应用(Application)层、应用框架(Framework)层和硬件抽象层(Hardware Abstraction Layer，HAL)，内核空间包括驱动(Driver)层，硬件系统包括扬声器、音频编解码器等，还可以包括耳机。应用层是音频体系的最上层，可通过编写一个应用程序来执行对应的逻辑操作，例如检测触发音频播放事件的应用程序，预先设置第一类应用程、第二类应用程序、第三类应用程序和第四类应用程序或者第一播放音量至第六播放音量，下发音频播放指令等。应用框架层包括音频控制接口和标准化插件模块负责提供音频播放形式控制接口，以及扬声器音量大小控制接口等。应用框架层提供了AudioTrack和AudioRecorder两个类，以及AudioManager、AudioService及AudioSystem类。在应用框架层和硬件抽象层之间还包括一个系统运行库(Libraries)层。我们知道，framework层的很多类，实际上只是应用程序使用Android库文件的“中介”而已。因为上层应用采用java语言编写，它们需要最直接的java接口的支持，这就是framework层存在的意义之一。而作为“中介”，它们并不会真正去实现 具体的功能，或者只实现其中的一部分功能，而把主要重心放在库中来完成。比如上面的AudioTrack、AudioRecorder、MediaPlayer和MediaRecorder等等在库中都能找到相对应的类。这一部分代码集中放置在工程的frameworks/av/media/libmedia中，多数是C++语言编写的。音频方面的硬件抽象层主要分为两部分，即AudioFlinger和AudioPolicyService，实际上后者并不是一个真实的设备，只是采用虚拟设备的方式来让厂商可以方便地定制出自己的策略。根据产品的不同，音频设备存在很大差异，在Android的音频架构中，这些问题都是由HAL层的audio.primary等来解决的，而不需要大规模地修改上层实现。硬件抽象层是应用框架层到驱动层的过渡，以实现底层硬件的兼容。驱动层按照音频编解码器的特性对其进行控制，确保音频编解码器可以正常工作，将音频编解码器获取到的音频数据提供给系统层。硬件系统包括扬声器和音频编解码器，扬声器用于播放音频数据控制音量大小，音频编解码器用于解析音频数据的格式，如MP3、WMA，负责音频可以正常播放。
图1b为本发明实施例提供的一种智能手机的音频处理硬件系统结构示意图。音频处理电路一般处于主控电路板中，由于不同手机的设计不同，音频处理电路的具体位置也可能不同。智能手机的音频处理电路主要包括音频信号处理电路、基带信号处理电路、音频功率放大器、耳机信号放大器、听筒、扬声器、麦克风及耳机接口等。其中，音频信号处理电路是整个音频处理电路的核心。音频处理电路主要由接收音频电路、送话电路、耳机通话电路等组成，包括模拟音频的模拟/数字(A/D)转换、数字/模拟(A/D)转换、数字语音信号处理及模拟音频放大电路等。
在通话时，首先通话本地端麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经内部的多模转换器进行A/D转换，得到数字音频信号；其次把此数字音频信号送到基带处理器，进行语音编码、信道编码等处理；再次进行加密、交织等一系列处理；最后送到基带处理器中的数字窄带制调模块进行调制，产生发射基带信号送入射频电路调制成发射中频，发送给通话对方。在接听电话时，首先从射频电路解调出接收基带信息，送到基带处理器内部进行数字窄带解调，分离出控制信号和语音信号；其次把语音信号进行解密、去交织、重组等一系列处理，然后进行信道解码、语音解码；最后得到纯正数字语音信号，送入语音信号处理器中的多模转换器进行D/A转换；还原成模拟音频信号后，经过音频功率放大后推动听筒发声。若选择免 提受话，基带处理器则关闭听筒受话放大器，启动免提受话放大管(振铃放大管)工作，把音频信号功率放大后推动扬声器发声。
在录音时，与上述过程类似，首先由麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经过A/D转换后得到数字音频信号，按照预设的音频格式进行编码及存储。在播放录音或其他音频文件时，将音频文件进行解码得到数字音频信号，经过D/A换后还原成模拟音频信号，把音频信号功率放大后推动扬声器发声。
本发明实施例中可预先在终端中存储预设音频文件，对该预设音频文件进行播放。预存音频文件以及预设音量等级可由设计人员根据实际情况进行选取，不同的声音播放器件对应的预设音频文件和/或预设音量等级可以不同，本发明实施例不做限定。麦克风采集的音频信号可以是上述的由机械声波信号转换而来的模拟音频信号，也可以是经过放大后的模拟音频信号，可根据两者的不同分别设置相应的下文中的预设条件，本发明实施例不作限定。为了方便终端与用户之间的交互，终端一般会向用户提供音量调节功能，用户可采用调节音量调节按钮或音量调节进度条等方式对终端播放声音的音量等级进行调整，而终端根据用户调整后的音量等级对需要播放的音频信号进行相应的放大处理，如功率放大，以满足用户的收听需求。不同的终端中对音量等级的划分策略可能不同，即具体的音量等级的总数量以及每个音量等级对应的音量大小都可能不同，本发明实施例不作限定。
图2给出了本发明实施例提供的一种移动终端的音量控制方法的流程图，本实施例的方法可以由移动终端的音量控制装置来执行，该装置可通过硬件和/或软件的方式实现，所述装置可作为移动终端一部分设置在所述移动终端的内部，本实施例提供的方法可适用于根据移动终端的工作状态对移动终端的各个应用程序的音频播放音量进行控制的情况。所述移动终端可以是智能手机、车载终端、平板电脑、台式电脑、笔记本、掌上电脑等设备。
如图2所示，本实施例提供的移动终端的音量控制方法包括以下步骤：
步骤101、确定移动终端的当前工作状态。
在某些实施方式中，所述确定移动终端的当前工作状态可以包括：定时监测移动终端的工作状态；或者，在检测到音频播放事件被触发时，确定移动终端的当前工作状态。其中，所述工作状态可以包括运行状态和待机状态，还可以包括工作性能参数状态，例如移动终端中央处理器(Central Processing Unit， CPU)的使用率、内存占用率和剩余电量等。
在本实施例中，可以定时监测移动终端的工作状态，每隔设定时间获取一次移动终端的当前工作状态，例如，每隔1秒钟获取一次。采用这种方式的好处是：工作状态获取方式简单易于实现。
还可以在检测到有音频播放事件被触发时，才获取移动终端的当前工作状态。例如，在接收到来电信号时，或者检测到用户作用于播放按键的触摸指令时，才获取移动终端的当前工作状态。采用这种方式的好处是：可以只有在触发音频播放事件时才去获取移动终端的工作状态，可以降低移动终端的功耗。
步骤102、根据所述当前工作状态确定移动终端中各个应用程序的音频播放音量。
在移动终端处于不同的工作状态下，不同应用程序对音频播放音量的需求是不同的。例如，在移动终端当前处于运行状态下时，说明移动终端正在被用户使用或者密切关注，那么当前被用户使用的应用程序，例如音乐或者游戏等应用的音量可以大一些，而来电铃声或者闹铃等应用的音量可以小一些。又例如，在移动终端当前处于待机状态下时，说明用户没有密切关注移动终端，那么可将音乐或者游戏等应用的音量设置的小一些，而来电铃声或者闹铃等应用的音量设置的大一些。
步骤103、控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
在上述步骤102确定了当前工作状态下各个应用程序对应的播放音量之后，在目标应用程序需要播放音频时，根据该目标应用程序对应的播放音量进行音频的播放。可以先根据移动终端的工作状态来确定各个应用程序各自对应的音量，以在应用程序在该工作状态下需要播放音频时按照该应用程序对应的音量进行音频的播放；也可以在应用程序需要播放音频的情况下，在播放音频之前根据移动终端的当前工作状态来确定该应用程序所对应的音量，以按照该应用程序所对应的音量进行音频的播放。
本实施例提供的方法，通过确定移动终端的当前工作状态，根据所述当前工作状态确定移动终端中各个应用程序的音频播放音量，控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放，可以根据移动终端的工作状态合理的控制各个应用程序的音频播放音量。
在上述实施例的基础上，还可以包括以下步骤：
步骤a1、获取移动终端的运动轨迹。
本实施例可通过移动终端的加速度传感器和陀螺仪来检测移动终端的运动轨迹。可以是用户持移动终端移动而使移动终端产生相应的运动轨迹。所述运动轨迹包括运动方向、运动速度和运动位移。
步骤a2、确定触发音频播放事件的当前应用程序。
示例性的，在来电响铃应用场景下，若检测到来电信号，则可确定触发音频播放事件的当前应用程序为电话；在音乐播放场景下，若检测到用户作用于播放按键的触摸指令时，可确定触发音频播放事件的当前应用程序为音乐播放器；在游戏运行场景下，若检测到背景声音或者人物角色声音被触发播放，可确定触发音频播放事件的当前应用程序为游戏。其中，所述当前应用程序为具体的某一个应用程序，例如，可确定音乐播放器为酷我音乐盒还是QQ音乐。
步骤a3、根据所述运动轨迹和所述当前应用程序，对所述当前应用程序的播放音量进行调节。
在移动终端中可预先存储各个应用程序下各自对应的运动轨迹和音量调节信息的预设对应关系表。其中，所述音量调节信息包括音量调节方向和音量调节大小。该步骤106可以包括：从所述预设对应关系表中查找所述当前应用程序下所述运动轨迹对应的音量调节信息；根据所述音量调节信息对所述当前应用程序的播放音量进行调节。示例性的，如下表1给出了本实施例提供的各个应用程序下各自对应的运动轨迹和音量调节信息的预设对应关系：
Figure PCTCN2017098178-appb-000001
在移动终端被置于手包中或者虚拟现眼镜中时，或者处于黑暗的环境中时， 用户不太方便去操作移动终端的音量键来控制移动终端的音量。那么，在这些应用场景下，可以通过移动终端的运动轨迹来实现移动终端的音量调节，提供了一种更加方便快捷的音量调整方式，而在不同的应用程序下可根据该应用的特点为应用程序预先设置移动终端的运动轨迹与音量调节的对应关系。
如上表1所示，在当前应用程序为闹钟时，若检测到移动终端的运动轨迹的运动方向为从上到下或者从下到上或者从左到右或者从右到左，运动速度为大于a米/秒，且运动位移为在所述运动方向上来回多次，那么可将闹铃的音量调节为静音。一般，现有手段是在闹钟响铃后需在移动终端的触摸屏上操作或者相应按键操作，才可以关闭闹铃，而本实施例通过检测移动终端的运动轨迹即可调节闹铃音量或者静音。在当前应用程序为音乐时，若移动终端的运动方向为从上到下，运动速度为大于a米/秒，且运动位移为从上到下一次，那么可将音乐的音量增大2个音量调节值。其中，a为可根据用户的需求进行设定，对于不同的当前使用用户也可设定不同的值，例如，a可以为0.5。所述音量调节值为移动终端中设置的最小单位调节音量，例如，每触发一次音量加/减的音量调节值。在应用程序为音乐或者游戏时，在不同的运动轨迹下，对应的音量调节信息类似，如表1，在此不再一一介绍。
进一步的，所述步骤105和步骤104的执行顺序可以调换，即先确定触发音频播放事件的当前应用程序，再获取移动终端的运动轨迹。例如，先确定触发音频播放事件的当前应用程序为闹铃，再获取移动终端的运动轨迹，并根据所述运动轨迹，对所述当前应用程序的播放音量进行调节。
图3给出了本发明实施例提供的另一种移动终端的音量控制方法的流程图，本实施例的方法可以由移动终端的音量控制装置来执行，该装置可通过硬件和/或软件的方式实现，所述装置可作为移动终端一部分设置在所述移动终端的内部，本实施例提供的方法可适用于在移动终端处于运行状态下时对移动终端的各个应用程序的音频播放音量进行控制的情况。
如图3所示，本实施例提供的移动终端的音量控制方法包括：
步骤201、确定移动终端的当前工作状态为运行状态。
在某些实施方式中，所述确定移动终端的当前工作状态为运行状态可以包括：若检测到移动终端当前存在处于运行状态的进程，则确定移动终端的当前工作状态为运行状态；或者，若检测到移动终端在设定时间内处于运动状态， 则确定移动终端的当前工作状态为运行状态。
用于确定移动终端处于运行状态的方式有很多种，例如可根据移动终端中央处理的使用率，内存占用率等来确定移动终端是否处于运行状态，在所述使用率或者内存占用率达到设定的比例时，即可确定移动终端处于运行状态。
还可以通过检测移动终端中当前是否存在正在运行的进程，若存在则确定移动终端处于运行状态。另外，还可以通过检测移动终端的运动状态，若移动终端在移动终端在设定时间内处于运动状态，则可确定移动终端处于运行状态。一般，用户在使用移动终端的过程中，不可避免的会产生一定的运动，而在没有使用移动终端的情况下，移动终端才处于相对静止的状态。由于移动终端的陀螺仪或者加速度传感器可以灵敏的感知移动终端的轻微运动，所以移动终端可以准确的感知移动终端的运动状态，在移动终端在设定时间内是处于运动状态的，那么说明用户在使用该移动终端，该移动终端处于运行状态中。通过移动终端的运动状态可以快速简便的获取到移动终端的工作状态。
步骤202、将预设的第一类应用程序的音频播放音量确定为第一播放音量。
步骤203、将预设的第二类应用程序的音频播放音量确定为第二播放音量。其中，所述第一播放音量小于所述第二播放音量。
在本实施例中，所述预设的第一类应用程序可以为电话、短信或者闹钟等应用程序，所述预设的第二类应用程序可以为音乐、视频或者游戏等。所述预设的第一类应用程序和第二类应用程序可以为预先存储在移动终端中的一个预设列表中，在确定了移动终端处于运行状态后，可从所述预设列表中获取预设的第一类应用程序或者预设的第二类应用程序，为所述预设的第一类应用程序或者预设的第二类应用程序设置其对应的播放音量。
一般移动终端在处于运行状态下时，用户是在密切关注和使用移动终端的，那对于电话铃声、短信铃声或者闹铃的声音是可以设置的小一些，这样设置的原因是：一方面可以防止在用户使用移动终端的过程中，被过大的电话铃声、短信铃声或者闹铃的通知声音吓到；另一方面，由于当前用户正在使用移动终端那么较小的通知声音也是可以达到通知用户的作用的，且可以降低移动终端的功耗。而对于用户在移动终端运行状态下操作的应用程序，例如音乐、视频或者游戏等应用程序则可以将播放音量设置的大一些。所以在本实施例中，确定了移动终端处于运行状态后，可将预设的第一类应用程序的音频播放音量确定为第一播放音量，可将预设的第二类应用程序的音频播放音量确定为第二播 放音量。其中，所述第一播放音量小于所述第二播放音量。示例性的，所述第二播放音量可以为移动终端当前的默认播放音量。
其中，所述预设的第一类应用程序和所述预设的第二类应用程序在不同的音频触发类型下可能是不同的，即对于某一个应用程序可根据其音频触发事件的触发类型，来确定该应用程序是属于预设的第一类应用程序还是第二类应用程序。例如，对于电话这个应用程序，若触发音频播放事件的触发类型为通知提示音类型，如来电铃声，那么在移动终端处于运行状态下时，可确定电话这个应用程序为预设的第一类应用程序，并确定其音频播放音量为较小的第一播放音量；若触发音频播放事件的触发类型为非通知提示音类型，如通话音量，那么在移动终端处于运行状态下时，可确定电话这个应用程序为预设的第二类应用程序，并确定其音频播放音量为较大的第二播放音量。其中，某个应用程序是属于预设第一类应用程序还是预设的第二类应用程序的确定方式可以包括：(1)预先设置一个预设列表，所述预设列表中包含该应用程序在不同音频播放事件触发类型下对应的所属预设类型(属于预设的第一类型应用程序或者预设的第二类应用程序)应用程序的条目，根据当前触发类型从所述预设列表中查找该应用程序所述的预设类型；(2)根据不同音频播放事件触发类型，预设设置多个预设子列表，每个预设子列表包含该应用程序在一种音频播放事件触发类型下对应的所属预设类型的条目，根据当前触发类型从对应的预设子列表中查找该应用程序所述的预设类型。
相应的，所述确定移动终端的当前工作状态为运行状态可以包括：在检测到音频播放事件被触发时，确定移动终端的当前工作状态为运行状态。所述根据所述当前工作状态确定移动终端中各个应用程序的音频播放音量可以包括：根据音频播放事件触发类型，确定预设的第一类应用程序和预设的第二类应用程序；将预设的第一类应用程序的音频播放音量确定为第一播放音量；将预设的第二类应用程序的音频播放音量确定为第二播放音量；其中，所述第一播放音量小于所述第二播放音量。
步骤204、控制所述预设的第一类应用程序按照所述第一播放音量进行音频的播放，以及控制所述预设的第二类应用程序按照所述第二播放音量进行音频的播放。
在预设的第一类应用程序有待播放的音频需要播放时，则按照第一播放音量进行音频的播放，在预设的第二类应用程序有待播放的音频需要播放时，则 按照第二音量进行播放。例如，按照第一播放音量播放电话铃声、短信铃声或者闹钟铃声，按照第二播放音量播放音乐、视频或者游戏等。又例如，可按照第一播放音量播放电话铃声，按照第二播放音量播放通话内容。
本实施例提供的方法，通过在确定移动终端为运行状态后，将预设的第一类应用程序的音频播放音量确定为第一播放音量，将预设的第二类应用程序的音频播放音量确定为第二播放音量，并控制预设的第一类应用程序按照所述第一播放音量进行音频的播放，以及控制预设的第二类应用程序按照所述第二播放音量进行音频的播放，可以在移动终端处于运行状态时，根据应用程序的所属类型对应用程序的播放音量进行合理的控制。
图4给出了本发明实施例提供的另一种移动终端的音量控制方法的流程图，本实施例的方法可以由移动终端的音量控制装置来执行，该装置可通过硬件和/或软件的方式实现，所述装置可作为移动终端一部分设置在所述移动终端的内部，本实施例提供的方法可适用于在移动终端处于待机状态下时对移动终端的各个应用程序的音频播放音量进行控制的情况。
如图4所示，本实施例提供的移动终端的音量控制方法包括：
步骤301、确定移动终端的当前工作状态为待机状态。
在某些实施方式中，所述确定移动终端的工作状态为待机状态可以包括：在检测到移动终端的屏幕处于锁屏状态时，确定移动终端的当前工作状态为待机状态。其中，所述锁屏状态与亮屏状态可以等同，也可以不同，例如当移动终端处于锁屏状态时，所述移动终端可能是熄屏状态，也可能是亮屏状态。
可以注册一个广播接收者BroadcastReceiver，例如注册一个android.intent.action.SCREEN_OFF这样的广播接收者来监听移动终端的屏幕状态，在监听到屏幕的锁屏广播消息后，可确定移动终端的当前工作状态为待机状态。
在某些实施方式中，所述确定移动终端的工作状态为待机状态可以包括：若检测待移动终端在第二设定时间内处于静止状态，则确定移动终端的当前工作状态为待机状态。一般，用户在使用移动终端的过程中，不可避免的会产生一定的运动，而在没有使用移动终端的情况下，移动终端才处于相对静止的状态。移动终端可以准确的感知移动终端的运动状态，在移动终端在第二设定时间内是处于静止状态的，那么说明用户没有在使用该移动终端，该移动终端处 于静止状态中。通过移动终端的运动状态可以快速简便的获取到移动终端的工作状态。
步骤302、将预设的第一类应用程序的音频播放音量确定为第三播放音量。
步骤303、将预设的第二类应用程序的音频播放音量确定为第四播放音量。其中，所述三播放音量大于所述第四播放音量。
在本实施例中，所述预设的第一类应用程序可以为电话、短信或者闹钟等应用程序，所述预设的第二类应用程序可以为音乐、视频或者游戏等。所述预设的第一类应用程序和第二类应用程序可以为预先存储在移动终端中的一个预设列表中，在确定了移动终端处于待机状态后，可从所述预设列表中获取预设的第一类应用程序或者预设的第二类应用程序，为所述预设的第一类应用程序或者预设的第二类应用程序设置其对应的播放音量。
一般移动终端在处于待机状态下时，用户是没有密切关注和使用移动终端的，那么对于电话铃声、短信铃声或者闹铃的声音是可以设置的大一些，这样可以防止用户由于听不到通知声音而错过电话、短信或者闹铃等。而对于音乐、视频或者游戏等应用程序，由于用户当前并没有关注，例如在锁屏状态下，音乐还在播放中，那么可将该音乐应用程序的音量设置的小一些。所以，在本实施例中，确定了移动终端处于待机状态后，可将预设的第一类应用程序的音频播放音量确定为第三播放音量，可将预设的第二类应用程序的音频播放音量确定为第四播放音量。其中，所述第三播放音量大于所述第四播放音量。示例性的，所述第三播放音量可以大于移动终端的当前默认播放音量，所述第四播放音量可以小于移动终端的当前默认播放音量。
步骤304、控制所述预设的第一类应用程序按照所述第三播放音量进行音频的播放，以及控制所述预设的第二类应用程序按照所述第四播放音量进行音频的播放。
在预设的第一类应用程序有待播放的音频需要播放时，则按照第三播放音量进行音频的播放，在预设的第二类应用程序有待播放的音频需要播放时，则按照第四音量进行播放。例如，按照第三播放音量播放电话铃声、短信铃声或者闹钟铃声，按照第四播放音量播放音乐、视频或者游戏等。
本实施例提供的方法，通过在确定移动终端为待机状态后，将预设的第一类应用程序的音频播放音量确定为第三播放音量，将预设的第二类应用程序的音频播放音量确定为第四播放音量，并控制预设的第一类应用程序按照所述第 三播放音量进行音频的播放，以及控制预设的第二类应用程序按照所述第四播放音量进行音频的播放，可以在移动终端处于待机状态时，根据应用程序的所属类型对应用程序的播放音量进行合理的控制。
图5给出了本发明实施例提供的另一种移动终端的音量控制方法的流程图，本实施例的方法可以由移动终端的音量控制装置来执行，该装置可通过硬件和/或软件的方式实现，所述装置可作为移动终端一部分设置在所述移动终端的内部，本实施例提供的方法可适用于根据移动终端的当前工作性能参数状态对移动终端的各个应用程序的音频播放音量进行控制的情况。所述工作性能参数包括中央处理器的使用率、内存占用率和剩余电量中的至少一项。
如图5所示，本实施例提供的移动终端的音量控制方法包括：
步骤401、确定移动终端的当前工作性能参数状态。
其中，所述工作性能参数包括移动终端的中央处理器的使用率、内存占用率和剩余电量。
步骤402、根据所述当前工作性能参数状态，确定移动终端中各个应用程序的音频播放音量。
在移动终端的中央处理器使用率较低，或者移动终端的内存占用率较低或者移动终端的剩余电量较大时，可确定各个应用程序的音频播放音量为移动终端的当前默认播放音量或者各自对应的预设音量；在移动终端的中央处理器的使用率较高，或者移动终端的内存占用率较高或者移动终端的剩余电量较小时，可以将应用程序的音量降低。
步骤403、控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
可控制优先级较低的应用程序按照降低后的第五播放音量进行音频的播放。而优先级较高的应用程序按照降低后的第六播放音量进行非音频的播放，其中，第五播放音量小于第六播放音量。所述第六播放音量小于移动终端的当前默认播放音量。

需要说明的是，本发明实施例中所提到的预设的第一类应用程序、第二类应用程序、第三类应用程序和第四类应用程序仅用于区别在不同情况下的不同类型的应用程序，并不用于限定移动终端中的所有应用程序被分为上述四类，也不用于限定绝对的类型分类，即四类应用程序中可以有交叉或者相同的应用程序。
图6给出了本发明实施例提供的一种移动终端的音量控制装置的结构示意图，该装置可由软件和/或硬件实现，集成在移动终端中。如图6所示，该移动终端的音量控制装置500包括当前工作状态确定模块51、音频播放音量确定模块52和音频播放控制模块53。
在所述装置500中，所述当前工作状态确定模块51，用于确定移动终端的当前工作状态。
在某些实施方式中，所述当前工作状态确定模块51确定移动终端的当前工作状态可以包括：定时监测移动终端的工作状态；或者，在检测到音频播放事 件被触发时，确定移动终端的当前工作状态。其中，所述工作状态可以包括运行状态和待机状态，还可以包括工作性能参数状态，例如移动终端中央处理器(Central Processing Unit，CPU)的使用率、内存占用率和剩余电量等。
在本实施例中，可以定时监测移动终端的工作状态，每隔设定时间获取一次移动终端的当前工作状态，例如，每隔1秒钟获取一次。采用这种方式的好处是：工作状态获取方式简单易于实现。
还可以在检测到有音频播放事件被触发时，才获取移动终端的当前工作状态。例如，在接收到来电信号时，或者检测到用户作用于播放按键的触摸指令时，才获取移动终端的当前工作状态。采用这种方式的好处是：可以只有在触发音频播放事件时才去获取移动终端的工作状态，可以降低移动终端的功耗。
在所述装置500中，所述音频播放音量确定模块52，用于根据所述当前工作状态确定移动终端中各个应用程序的音频播放音量。
在移动终端处于不同的工作状态下，不同应用程序对音频播放音量的需求是不同的。例如，在移动终端当前处于运行状态下时，说明移动终端正在被用户使用或者密切关注，那么当前被用户使用的应用程序，例如音乐或者游戏等应用的音量可以大一些，而来电铃声或者闹铃等应用的音量可以小一些。又例如，在移动终端当前处于待机状态下时，说明用户没有密切关注移动终端，那么可将音乐或者游戏等应用的音量设置的小一些，而来电铃声或者闹铃等应用的音量设置的大一些。
在所述装置500中，所述音频播放控制模块53，用于控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
在音频播放音量确定模块52确定了当前工作状态下各个应用程序对应的播放音量之后，在目标应用程序需要播放音频时，音频播放控制模块53根据该目标应用程序对应的播放音量进行音频的播放。可以先根据移动终端的工作状态来确定各个应用程序各自对应的音量，以在应用程序在该工作状态下需要播放音频时按照该应用程序对应的音量进行音频的播放；也可以在应用程序需要播放音频的情况下，在播放音频之前根据移动终端的当前工作状态来确定该应用程序所对应的音量，以按照该应用程序所对应的音量进行音频的播放。
本实施例提供的装置，通过确定移动终端的当前工作状态，根据所述当前工作状态确定移动终端中各个应用程序的音频播放音量，控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放，可以根据移动终端的工作状 态合理的控制各个应用程序的音频播放音量。
该装置500还可以包括运动轨迹获取模块54、当前应用程序确定模块55和播放音量调节模块56。
在本实施例中，所述运动轨迹获取模54，用于获取移动终端的运动轨迹。
在本实施例中，运动轨迹获取模54可通过移动终端的加速度传感器和陀螺仪来检测移动终端的运动轨迹。可以是用户持移动终端移动而使移动终端产生相应的运动轨迹。所述运动轨迹包括运动方向、运动速度和运动位移。
所述当前应用程序确定模块55，用于确定触发音频播放事件的当前应用程序。
示例性的，在来电响铃应用场景下，若当前应用程序确定模块55检测到来电信号，则可确定触发音频播放事件的当前应用程序为电话；在音乐播放场景下，若当前应用程序确定模块55检测到用户作用于播放按键的触摸指令时，可确定触发音频播放事件的当前应用程序为音乐播放器；在游戏运行场景下，若当前应用程序确定模块55检测到背景声音或者人物角色声音被触发播放，可确定触发音频播放事件的当前应用程序为游戏。其中，所述当前应用程序为具体的某一个应用程序，例如，可确定音乐播放器为酷我音乐盒还是QQ音乐。
所述播放音量调节模块56，用于根据所述运动轨迹信息和所述当前应用程序，对所述当前应用程序的播放音量进行调节。
在移动终端中可预先存储各个应用程序下各自对应的运动轨迹和音量调节信息的预设对应关系表。其中，所述音量调节信息包括音量调节方向和音量调节大小。该播放音量调节模块56可用于：从所述预设对应关系表中查找所述当前应用程序下所述运动轨迹对应的音量调节信息；根据所述音量调节信息对所述当前应用程序的播放音量进行调节。示例性的，如下表1给出了本实施例提供的各个应用程序下各自对应的运动轨迹和音量调节信息的预设对应关系：
Figure PCTCN2017098178-appb-000002
Figure PCTCN2017098178-appb-000003
在移动终端被置于手包中或者虚拟现眼镜中时，或者处于黑暗的环境中时，用户不太方便去操作移动终端的音量键来控制移动终端的音量。那么，在这些应用场景下，可以通过移动终端的运动轨迹来实现移动终端的音量调节，提供了一种更加方便快捷的音量调整方式，而在不同的应用程序下可根据该应用的特点为应用程序预先设置移动终端的运动轨迹与音量调节的对应关系。
如上表1所示，在当前应用程序为闹钟时，若播放音量调节模块56检测到移动终端的运动轨迹的运动方向为从上到下或者从下到上或者从左到右或者从右到左，运动速度为大于a米/秒，且运动位移为在所述运动方向上来回多次，那么可将闹铃的音量调节为静音。一般，现有手段是在闹钟响铃后需在移动终端的触摸屏上操作或者相应按键操作，才可以关闭闹铃，而本实施例通过检测移动终端的运动轨迹即可调节闹铃音量或者静音。在当前应用程序为音乐时，若播放音量调节模块56检测到移动终端的运动方向为从上到下，运动速度为大于a米/秒，且运动位移为从上到下一次，那么可将音乐的音量增大2个音量调节值。其中，a为可根据用户的需求进行设定，对于不同的当前使用用户也可设定不同的值，例如，a可以为0.5。所述音量调节值为移动终端中设置的最小单位调节音量，例如，每触发一次音量加/减的音量调节值。在应用程序为音乐或者游戏时，在不同的运动轨迹下，对应的音量调节信息类似，如表1，在此不再一一介绍。
进一步的，所述运动轨迹获取模块54和当前应用程序确定模块55的功能实现顺序可以调换，即先由当前应用程序确定模块55确定触发音频播放事件的当前应用程序，再由运动轨迹获取模块54获取移动终端的运动轨迹。例如，先当前应用程序确定模块55确定触发音频播放事件的当前应用程序为闹铃，再由运动轨迹获取模块54获取移动终端的运动轨迹，并根据所述运动轨迹，对所述当前应用程序的播放音量进行调节。
图7给出了本发明实施例提供的另一种移动终端的音量控制装置的结构示意图。该装置600包括当前工作状态确定模块61、音频播放音量确定模块62和音频播放控制模块63，所述音频播放音量确定模块62包括第一音频播放音量确定子模块621和第二音频播放音量确定子模块622。
在某些实施方式中，所述当前工作状态确定模块61具体用于：确定移动终端的当前工作状态为运行状态。
在某些实施方式中，所述当前工作状态确定模块61确定移动终端的当前工作状态为运行状态可以包括：若检测到移动终端当前存在处于运行状态的进程，则确定移动终端的当前工作状态为运行状态；或者，若检测到移动终端在设定时间内处于运动状态，则确定移动终端的当前工作状态为运行状态。
当前工作状态确定模块61用于确定移动终端处于运行状态的方式有很多种，例如可根据移动终端中央处理的使用率，内存占用率等来确定移动终端是否处于运行状态，在所述使用率或者内存占用率达到设定的比例时，即可确定移动终端处于运行状态。
当前工作状态确定模块61还可以通过检测移动终端中当前是否存在正在运行的进程，若存在则确定移动终端处于运行状态。另外，还可以通过检测移动终端的运动状态，若移动终端在移动终端在设定时间内处于运动状态，则可确定移动终端处于运行状态。一般，用户在使用移动终端的过程中，不可避免的会产生一定的运动，而在没有使用移动终端的情况下，移动终端才处于相对静止的状态。由于移动终端的陀螺仪或者加速度传感器可以灵敏的感知移动终端的轻微运动，所以移动终端可以准确的感知移动终端的运动状态，在移动终端在设定时间内是处于运动状态的，那么说明用户在使用该移动终端，该移动终端处于运行状态中。通过移动终端的运动状态可以快速简便的获取到移动终端的工作状态。
在所述装置600中，所述第一音频播放音量确定子模块621，用于将预设的第一类应用程序的音频播放音量确定为第一播放音量。
所述第二音频播放音量确定子模块622，用于将预设的第二类应用程序的音 频播放音量确定为第二播放音量。其中，所述第一播放音量小于所述第二播放音量。
在本实施例中，所述预设的第一类应用程序可以为电话、短信或者闹钟等应用程序，所述预设的第二类应用程序可以为音乐、视频或者游戏等。所述预设的第一类应用程序和第二类应用程序可以为预先存储在移动终端中的一个预设列表中，在当前工作状态确定模块61确定了移动终端处于运行状态后，第一音频播放音量确定子模块621可从所述预设列表中获取预设的第一类应用程序，为所述预设的第一类应用程序设置其对应的播放音量，第二音频播放音量确定子模块622可从所述预设列表中获取预设的第二类应用程序，为所述预设的第二类应用程序设置其对应的播放音量。
一般移动终端在处于运行状态下时，用户是在密切关注和使用移动终端的，那对于电话铃声、短信铃声或者闹铃的声音是可以设置的小一些，这样设置的原因是：一方面可以防止在用户使用移动终端的过程中，被过大的电话铃声、短信铃声或者闹铃的通知声音吓到；另一方面，由于当前用户正在使用移动终端那么较小的通知声音也是可以达到通知用户的作用的，且可以降低移动终端的功耗。而对于用户在移动终端运行状态下操作的应用程序，例如音乐、视频或者游戏等应用程序则可以将播放音量设置的大一些。所以在本实施例中，确定了移动终端处于运行状态后，可将预设的第一类应用程序的音频播放音量确定为第一播放音量，可将预设的第二类应用程序的音频播放音量确定为第二播放音量。其中，所述第一播放音量小于所述第二播放音量。示例性的，所述第二播放音量可以为移动终端当前的默认播放音量。
其中，所述预设的第一类应用程序和所述预设的第二类应用程序在不同的音频触发类型下可能是不同的，即对于某一个应用程序可根据其音频触发事件的触发类型，来确定该应用程序是属于预设的第一类应用程序还是第二类应用程序。例如，对于电话这个应用程序，若触发音频播放事件的触发类型为通知提示音类型，如来电铃声，那么在移动终端处于运行状态下时，可确定电话这个应用程序为预设的第一类应用程序，并确定其音频播放音量为较小的第一播放音量；若触发音频播放事件的触发类型为非通知提示音类型，如通话音量， 那么在移动终端处于运行状态下时，可确定电话这个应用程序为预设的第二类应用程序，并确定其音频播放音量为较大的第二播放音量。其中，某个应用程序是属于预设第一类应用程序还是预设的第二类应用程序的确定方式可以包括：(1)预先设置一个预设列表，所述预设列表中包含该应用程序在不同音频播放事件触发类型下对应的所属预设类型(属于预设的第一类型应用程序或者预设的第二类应用程序)应用程序的条目，根据当前触发类型从所述预设列表中查找该应用程序所述的预设类型；(2)根据不同音频播放事件触发类型，预设设置多个预设子列表，每个预设子列表包含该应用程序在一种音频播放事件触发类型下对应的所属预设类型的条目，根据当前触发类型从对应的预设子列表中查找该应用程序所述的预设类型。
相应的，所述当前工作状态确定模块61可用于：在检测到音频播放事件被触发时，确定移动终端的当前工作状态为运行状态。所述第一音频播放音量确定子模块621可用于：根据音频播放事件触发类型，确定预设的第一类应用程序；将预设的第一类应用程序的音频播放音量确定为第一播放音量；所述第二音频播放音量确定子模块621可用于：确定预设的第二类应用程序；将预设的第二类应用程序的音频播放音量确定为第二播放音量；其中，所述第一播放音量小于所述第二播放音量。
在所述装置600中，所述音频播放控制模块63，用于控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
在预设的第一类应用程序有待播放的音频需要播放时，则音频播放控制模块63按照第一播放音量进行音频的播放，在预设的第二类应用程序有待播放的音频需要播放时，则音频播放控制模块63按照第二音量进行播放。例如，按照第一播放音量播放电话铃声、短信铃声或者闹钟铃声，按照第二播放音量播放音乐、视频或者游戏等。又例如，可按照第一播放音量播放电话铃声，按照第二播放音量播放通话内容。
本实施例提供的装置，通过在确定移动终端为运行状态后，将预设的第一类应用程序的音频播放音量确定为第一播放音量，将预设的第二类应用程序的音频播放音量确定为第二播放音量，并控制预设的第一类应用程序按照所述第 一播放音量进行音频的播放，以及控制预设的第二类应用程序按照所述第二播放音量进行音频的播放，可以在移动终端处于运行状态时，根据应用程序的所属类型对应用程序的播放音量进行合理的控制。
图8给出了本发明实施例提供的另一种移动终端的音量控制装置的结构示意图。该装置700包括当前工作状态确定模块71、音频播放音量确定模块72和音频播放控制模块73，其中，所述音频播放音量确定模块72包括第三音频播放音量确定子模块721、第四音频播放音量确定子模块722。

在某些实施方式中，所述当前工作状态确定模块71确定移动终端的工作状态为待机状态可以包括：在检测到移动终端的屏幕处于锁屏状态时，确定移动终端的当前工作状态为待机状态。其中，所述锁屏状态与亮屏状态可以等同，也可以不同，例如当移动终端处于锁屏状态时，所述移动终端可能是熄屏状态，也可能是亮屏状态。
可以注册一个广播接收者BroadcastReceiver，例如注册一个android.intent.action.SCREEN_OFF这样的广播接收者来监听移动终端的屏幕状态，在监听到屏幕的锁屏广播消息后，可确定移动终端的当前工作状态为待机状态。
在某些实施方式中，所述当前工作状态确定模块71可用于：若检测待移动终端在第二设定时间内处于静止状态，则确定移动终端的当前工作状态为待机状态。一般，用户在使用移动终端的过程中，不可避免的会产生一定的运动，而在没有使用移动终端的情况下，移动终端才处于相对静止的状态。移动终端可以准确的感知移动终端的运动状态，在移动终端在第二设定时间内是处于静止状态的，那么说明用户没有在使用该移动终端，该移动终端处于静止状态中。通过移动终端的运动状态可以快速简便的获取到移动终端的工作状态。
在所述装置700中，所述第三音频播放音量确定子模块721，用于将预设的第一类应用程序的音频播放音量确定为第三播放音量。
在所述装置700中，所述第四音频播放音量确定子模块722，用于将预设的第二类应用程序的音频播放音量确定为第四播放音量；其中，所述三播放音量大于所述第四播放音量。
在本实施例中，所述预设的第一类应用程序可以为电话、短信或者闹钟等应用程序，所述预设的第二类应用程序可以为音乐、视频或者游戏等。所述预设的第一类应用程序和第二类应用程序可以为预先存储在移动终端中的一个预设列表中，在当前工作状态确定模块71确定了移动终端处于待机状态后，第三音频播放音量确定子模块721可从所述预设列表中获取预设的第一类应用程序，为所述预设的第一类应用程序设置其对应的播放音量，所述第四音频播放音量确定子模块722可从所述预设列表中获取预设的第二类应用程序，为所述预设的第二类应用程序设置其对应的播放音量。
一般移动终端在处于待机状态下时，用户是没有密切关注和使用移动终端的，那么对于电话铃声、短信铃声或者闹铃的声音是可以设置的大一些，这样可以防止用户由于听不到通知声音而错过电话、短信或者闹铃等。而对于音乐、视频或者游戏等应用程序，由于用户当前并没有关注，例如在锁屏状态下，音乐还在播放中，那么可将该音乐应用程序的音量设置的小一些。所以，在本实施例中，当前工作状态确定模块71确定了移动终端处于待机状态后，第三音频播放音量确定子模块721可将预设的第一类应用程序的音频播放音量确定为第三播放音量，第四音频播放音量确定子模块722可将预设的第二类应用程序的音频播放音量确定为第四播放音量。其中，所述第三播放音量大于所述第四播放音量。示例性的，所述第三播放音量可以大于移动终端的当前默认播放音量，所述第四播放音量可以小于移动终端的当前默认播放音量。
在所述装置700中，所述音频播放控制模块73，用于控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
在预设的第一类应用程序有待播放的音频需要播放时，则音频播放控制模块73按照第三播放音量进行音频的播放，在预设的第二类应用程序有待播放的音频需要播放时，则音频播放控制模块73按照第四音量进行播放。例如，按照第三播放音量播放电话铃声、短信铃声或者闹钟铃声，按照第四播放音量播放 音乐、视频或者游戏等。
本实施例提供的装置，通过在确定移动终端为待机状态后，将预设的第一类应用程序的音频播放音量确定为第三播放音量，将预设的第二类应用程序的音频播放音量确定为第四播放音量，并控制预设的第一类应用程序按照所述第三播放音量进行音频的播放，以及控制预设的第二类应用程序按照所述第四播放音量进行音频的播放，可以在移动终端处于待机状态时，根据应用程序的所属类型对应用程序的播放音量进行合理的控制。
图9给出了本发明实施例提供的另一种移动终端的音量控制装置的结构示意图。该装置800包括当前工作状态确定模块81、音频播放音量确定模块82和音频播放控制模块83，其中，所述音频播放音量确定模块82包括设定状态确定子模块821、第五音频播放音量确定子模块822和第六音频播放音量确定子模块823。
在某些实施方式中，所述当前工作状态确定模块81具体用于：确定移动终端的当前工作性能参数状态，所述工作性能参数包括中央处理器的使用率、内存占用率和剩余电量。
在某些实施方式中，所述音频播放音量确定模块82具体用于：根据所述当前工作性能参数状态，确定移动终端中各个应用程序的音频播放音量。
在移动终端的中央处理器使用率较低，或者移动终端的内存占用率较低或者移动终端的剩余电量较大时，音频播放音量确定模块82可确定各个应用程序的音频播放音量为移动终端的当前默认播放音量或者各自对应的预设音量；在移动终端的中央处理器的使用率较高，或者移动终端的内存占用率较高或者移动终端的剩余电量较小时，音频播放音量确定模块82可以将应用程序的音量降低。
在所述装置800中，所述音频播放控制模块83，用于控制所述各个应用程序按照各自对应的音频播放音量进行音频的播放。
