具体实施方式
下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
在更加详细地讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将各步骤描述成顺序的处理，但是其中的许多步骤可以被并行地、并发地或者同时实施。此外，各步骤的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
图1为本发明实施例提供的一种音量调节方法的流程示意图，该方法可以由本发明实施例所提供的音量调节装置执行，其中该装置可由软件和/或硬件实现，一般可集成在移动终端中。如图1所示，该方法包括：
S101、检测移动终端中安装的扬声器的阻抗值。
扬声器往往配置于移动终端内部，不同的移动终端的配置方式及配置位置均不尽相同。但是，移动终端的扬声器的工作原理大致相同，均是一种将电信号转换成声音信号进行重放的元件。目前最广泛使用的是电动式扬声器，它由 振动膜、音圈、永久磁铁以及支架等组成。
当扬声器的音圈通入音频电流后，音圈在电流的作用下便产生了交变磁场，永久磁铁同时也产生一个大小与方向不变的恒定磁场。由于音圈所产生的磁场大小和方向随音频电流的变化不断地在改变，这样两个磁场的相互作用使音圈作垂直于音圈中的电流方向的运动，由于音圈和振动膜相连，从而音圈带动振动膜振动，由振动膜振动引起空气的振动面发出声响。
输出给音圈的电流越大，其磁场的作用力就越大.振动膜振动的幅度也就越大，声音则越响。因此，对于扬声器的阻抗值，直接影响扬声器内部音圈的电流，所以，对于扬声器的阻抗值的检测尤为重要。
扬声器的阻抗值的检测方式有很多种，可以根据加入适当电压，通过检测电流的形式，进而计算确定扬声器的阻抗值。还可以在为扬声器输入一个固定电流的情况下，通过检测其产生的音量与理论值之间的差距确定扬声器的阻抗值。
由于扬声器的阻抗值由电器元件的内阻，如音圈的直流阻抗，电感产生的阻抗以及反电动势产生的阻抗等构成。因此，在对移动终端的扬声器的阻抗值的测试时，为了免除不同频率下电感产生的阻抗以及反电动势产生的阻抗收到频率不同的影响而表现出不同的阻抗值，可以在扬声器的阻抗值测试时，采用一个固定的频率或者固定频段的音频文件进行测试。这样可以使对于扬声器的阻抗值的检测结果更加准确，减小其他因素的干扰。
S102、依据所述阻抗值确定对应的音量调节信息。
其中，音量调节信息可以是一个目标音量信息，如根据当前阻抗值，确定目标音量可以是40分贝，则把音量为40分贝作为一个目标音量。音量调节信息还可以是一种调节量，如根据当前阻抗值，则可以相应的将移动终端的音量增大10分贝，例如音量为30分贝，则可以增大10分贝至40分贝，例如原来音量为50分贝，则可以增大10分贝至60分贝。还可以是修改音视频文件中的音频数据，将其振幅增大或者减小。
根据检测到的扬声器的阻抗值，确定与之对应的音量调节等级，可以是根据检测到的扬声器的阻抗值，与该扬声器理论阻抗值，确定与之对应的音量调节等级。如扬声器当前阻抗值是6000毫欧，该扬声器的理论阻抗值为5000毫欧，则其影响到音圈的电流势必使声音减小，则音量调节信息可以增大原输出音量值的25％，则输出音量值可以接近原始设定的音量值。
S103、依据所述音量调节信息对所述移动终端的音量进行调节。
根据确定的音量调节信息，对移动终端的音量做出适应性调节。如音量调节信息是某一个目标音量值，则可以调整与至该音量对应的音量等级，如音量调节信息是某一个调节值，则对当前音量等级做出相应调节，如音量调节信息是对于音频数据的一种调节参数，则对该音频数据的振幅做出相应调整。
本发明实施例提供的技术方案，通过检测移动终端的扬声器的阻抗值，并依据所述阻抗值确定预置对应的音量调节信息，再根据所述调节信息对移动终端的音量进行调节。通过采用上述技术方案，可以实现自动调节移动终端扬声器的播放音量的效果。
在另一个实施例中，还可以直接通过调整输入到移动终端的扬声器的音圈的电流。这样设置的好处是还可以按照移动终端原有的音量等级进行音量调节，只不过每一个音量等级所对应的输入到音圈的电流发生了变化，可以保留用户原有的音量调节习惯。
在上述技术方案的基础上，可选的，所述检测移动终端扬声器的阻抗值包括：检测到音频测试文件播放时，通过功放芯片检测移动终端中安装的扬声器的阻抗值。其中，音频测试文件可以在移动终端出厂时就配置在移动终端的存储器内，也可以通过下载、共享等方式进行获取。音频测试文件播放时，通过功放芯片检测移动终端的扬声器的阻抗值。通过功放芯片检测扬声器的阻抗值易于操作且检测值准确，提高了本技术方案的适用性。
图2为本发明实施例提供的另一种音量调节方法的流程示意图，在上述技术方案的基础上，对所述音量调节方法进行了进一步的优化。
如图2所示，所述音量调节方法包括：
S201、检测到音频测试文件播放时，通过功放芯片检测移动终端中安装的扬声器的阻抗值。
其中，音频测试文件可以是某一恒定频段或者恒定频段范围，以及恒定振幅或者恒定振幅范围的文件。在播放音频测试文件时，可以通过功放芯片检测扬声器的阻抗值，其中利用功放芯片检测时可以采用恒流源测试以及恒压源测试两种方式，还可以采用其他能够获得扬声器阻抗值的测试方式。
S202、获取记录的和所述音频测试文件对应的所述扬声器的历史阻抗值，其中，所述历史阻抗值包括在预设时长之前对所述扬声器进行检测得到的阻抗值。
其中，历史阻抗值可以是移动终端刚刚使用时的阻抗值，也可以是使用一段时间之后的曾经检测过的阻抗值。因为随着移动终端的使用，其扬声器的阻抗值会越来越大，但是变化情况可能因为不同的设备而不同。本实施例提供的采用功放芯片检测扬声器阻抗值的方法，可以根据检测数据判断当前扬声器的老化情况，为测试移动终端的性能提供数据支持。
本发明实施例对于同一音频测试文件进行多次检测，可以是定期检测，也可以是不定期检测。在每一次检测后记录扬声器的阻抗值的测试结果，并对预设时长之前测试得到的阻抗值进行数据提取，其中，预设时长可以是10天或者30天等，一个相对较长的时间，这样设置可以得到更加明显的效果。值得说明的是，如果当前移动终端的首次测试结果与当前测试时间间隔没有超过预设时长，则可以以首次测试结果为准。
每次检测的测试结果可以记录在一个阻抗值检测结果记录文件当中，可以存储在移动终端的存储器当中，记录阻抗值检测结果的同时，可以记录阻抗值测试日期以及时间，还可以检测阻抗值测试次数。
值得说明的是，本技术方案的S201和S202在发生时序上并非绝对，也可以先执行S202的动作再执行S201，或者两个步骤同时进行。
S203、依据所述历史阻抗值和当前检测得到的所述阻抗值确定对应的音量调节信息。
其中，可以根据历史阻抗值与当前检测得到的阻抗值相差的大小，或者相差的倍数，确定与当前阻抗值所对应的音量调节信息，例如，历史阻抗值为5000毫欧，当前阻抗值为5350毫欧，则可以利用二者间的差值或者利用二者的比值确定音量调节信息。
S204、依据所述音量调节信息对所述移动终端的音量进行调节。
本技术方案在上述各技术方案的基础上，提供了通过获取历史阻抗值以及当前阻抗值，确定音量调节信息的方法，这种方法可以为音量调节提供计算基础，是调节结果更加准确。

其中，标准阻抗值可以是原始的扬声器阻抗值，或者说是扬声器在出厂时的阻抗值，该标注阻抗值可以在移动终端出厂前检测并存储在移动终端的内存中，也可以是根据该型号的移动终端扬声器的阻抗值确定一个平均值作为阻抗标准值，还可以是用户在使用移动终端一定时间内测定的阻抗值作为标准阻抗值。标准阻抗值可以是对音频测试文件进行播放时被测定。这样设置的好处是可以控制变量，使检测结果更加准确。
S303、依据所述标准阻抗值和当前检测得到的所述阻抗值确定对应的音量调节信息。
相应的，也可以采用上述技术方案中的做差值和做比值两种方式，确定音量调节信息。
S304、依据所述音量调节信息对所述移动终端的音量进行调节。
本技术方案在上述各技术方案的基础上，提供了一种根据标准阻抗值和当前阻抗值确定音量调节信息的方法，这样设置的好处是使用标准阻抗值与当前检测的阻抗值进行计算更加准确，更加清晰的反映出扬声器在使用过程中阻抗值的变化情况，进而使移动终端的音量调节更加准确。
图4为本发明实施例提供的另一种音量调节方法的流程示意图，在上述技术方案的基础上，对所述音量调节方法进行了进一步的优化。
如图4所示，所述音量调节方法包括：
S401、检测到移动终端开始播放音视频时，通过功放芯片检测所述移动终端中安装的扬声器的阻抗值。
其中，音视频文件包括音频文件和视频文件，还可以包括其他可以发声的文件。检测移动终端开始播放音视频文件的方式可以是通过读取移动终端的进程，以及读取接口信息等方式，还可以是检测用户的操作指令等。当检测到移动终端播放音视频时，通过功放芯片检测移动终端的扬声器的阻抗值。
S402、确定当前播放的所述音视频的振幅曲线。
其中，振幅曲线可以是振幅随时间变化的曲线，也可以是分贝值随时间变化的曲线。振幅曲线可以是由音视频文件内部解码出来，得到音频数字信号，对该数字信号进行采样，可以得到振幅值，进而确定的振幅曲线。
S403、依据所述振幅曲线以及所述阻抗值确定对应的音量调节信息。
其中，振幅曲线可以根据振幅的高、中、低划分为三个阶段，每个阶段的 分界可以酌情确定，本实施例对此不作限定。
根据振幅曲线以及所述阻抗值确定对应的音量调节信息，可以是根据振幅曲线的阶段以及阻抗值确定对应的音量调节信息。如，振幅曲线为低振幅阶段，可以认为是噪声信号，对其进行抑制，振幅曲线为中振幅阶段，可以结合阻抗值做出适当的振幅系数，如对其进行0.8-1.2倍的缩放，振幅曲线为高振幅阶段，则可以减小振幅系数，如对其进行0.4-0.8倍的缩放。
根据振幅曲线以及所述阻抗值确定对应的音量调节信息，还可以是根据振幅曲线中，高振幅阶段与低振幅阶段的比例，并结合阻抗值，确定对应的音量调节信息。其中，高振幅阶段与低振幅阶段的比例可以表现出当前音视频文件的音频振幅的平均水平，如果偏低，可以乘以一个大于1的系数，如果偏高，可以乘以一个小于1的系数。
S404、依据所述音量调节信息对所述移动终端的音量进行调节。
本技术方案在上述各技术方案的基础上，提供了一种以音视频文件的振幅曲线和扬声器的阻抗值确定音量调节信息的方法，本方法在通过阻抗值确定音量调节信息的基础上，增加了播放的音视频文件的振幅曲线作为参考信息，使得音量调节信息对音量的调节结果更加符合用户对于音量的需求。
在上述各技术方案的基础上，可选的，所述依据所述振幅曲线以及所述阻抗值确定对应的音量调节信息包括：依据所述振幅曲线、所述阻抗值以及预设调节表确定对应的音量调节信息。其中，预设调节表可以是音量调节信息与振幅曲线和阻抗值的对应关系表。这样设置的好处是可以根据预设音量表快速、准确的确定音量调节信息，提高了移动终端扬声器音量调节的响应速度，提高了用户的使用体验。

其中，移动终端播放的音源的振幅曲线可以是移动终端当前所播放的音视 频文件中解码出的音频文件。根据音量调节信息对音源的振幅曲线进行调节，可以是把音量调节信息设置为一个调节系数，该调节系数可以是音源的振幅曲线中，与振幅做乘法或者加法的系数。如，音量调节信息为1.2，可以是把振幅曲线中，所有振幅都乘以1.2倍进行调节。
S504、依据所述音量调节信息中的目标音量值对所述移动终端当前的音量值进行调节。
其中，音量调节信息可以包括目标音量值，该目标音量值即为根据音量调节信息对音量做出调节的目标值。如音量调节信息中包括的目标音量值为12级，则可以将移动终端的音量等级调整到12级。如音量调节信息中包括的目标音量值为80分贝，则可以将移动终端的音量等级调整到80分贝。
S505、依据所述音量调节信息中的音量改变值对所述移动终端当前的音量值进行调节。

值得说明的是，本实施例中在确定音量调节信息之后，提供了对音量进行调节的三种方式，本领域技术人员由此方案不难得出，将上述三种方式进行任意组合，对移动终端的扬声器音量做出调节。所以，上述三种调节方式的任意组合形式也属于本申请文件权利要求书的保护范围。
