应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。

本申请实施例提供了一种扬声器的功耗控制方法，图1为本申请实施例提供的一种扬声器的功耗控制方法的流程图，图2为本申请实施例提供的一种扬声器的功耗控制方法的示意图，图3为本申请实施例提供的另一种扬声器的功耗控制方法的示意图，如图1、图2或图3所示，该方法包括：
步骤102、通过环境信息采集设备获取环境状态信息。
本申请实施例中，各步骤由电子设备执行。例如，电子设备包括手机、平板电脑、计算机或可穿戴设备。
本申请实施例中，步骤102之前还包括获取音频流，并对音频流进行常规音频处理，生成处理后的音频流。
本申请实施例中，环境信息采集设备包括麦克风、光传感器或温度传感器。
本申请实施例中，环境状态信息包括环境声音信息、环境光亮度信息或环境温度信息。
例如，通过麦克风获取环境声音信息，通过光传感器获取环境光亮度信息，通过温度传感器获取环境温度信息。
步骤104、通过环境状态分析模块对环境状态信息进行分析，生成环境状态结果。
本申请实施例中，环境状态结果包括环境的低频噪声程度。例如，通过环境状态分析模块对环境声音信息进行分析，生成环境的低频噪声程度。
步骤106、接收用户输入的模式选择结果。
本步骤中，用户输入模式选择结果，例如，模式选择结果包括性能模式、平衡模式或省电模式。
步骤108、通过功耗参数计算模块根据环境状态结果和模式选择结果，生成功耗控制参数。
具体地，通过功耗参数计算模块根据预置的扬声器参数、环境状态结果和模式选择结果，生成功耗控制参数。
作为一种可选方案，基于声音掩蔽效应模型，结合由用户选择的模选择结果，生成模式选择结果对应的功耗控制参数。
本申请实施例中，功耗控制参数包括高通滤波器截止频率参数，该高通滤波器截止频率参数是可调的，具体的高通滤波器截止频率参数的设置由功耗控制参数计算模块生成。
例如，在省电模式下，设置高通滤波器截止频率为600Hz，那么扬声器将仅输出600Hz以上的信号。由于微型扬声器在低频段的功率消耗比例很大，这样的操作将极大地减小微型扬声器的功耗，典型值为节省50%，从而起到省电的目的。
步骤110、通过功耗抑制模块根据功耗控制参数对扬声器进行功耗控制。
本申请实施例中，功耗抑制模块包括高通滤波器。
本申请实施例中，可通过功耗抑制模块根据功耗控制参数对处理后的音频流进行功耗控制，使得扬声器根据功耗控制参数进行功放，扬声器的功耗能够减小。
本申请实施例中，嘈杂环境中的低频噪声强度很大，这是已经被广泛认知的。例如，对于降噪耳机而言，其所降低的噪声主要也是低频噪声，图4为微型扬声器典型频响曲线的示意图，图5为声音的掩蔽效应的示意图，如图4所示，对于电子设备所使用的微型扬声器而言，同样众所周知的，微型扬声器的低频响应是相对较弱的。也就意味着，在微型扬声器f0（谐振频率）之前，低频响应是不足的，并且频率越低，声压级越小。对于微型扬声器而言，微型扬声器f0的典型值可以在800Hz左右。如图5所示，由于“掩蔽效应”的存在，可以知道，当外界声音中低频响度很大时，会很容易掩蔽电子设备的微型扬声器所发出来的响度较低的低频声音。
本申请实施例中，图6为环境噪声中的低频噪声频谱的示意图，如图6所示，在有大量低频噪声的嘈杂环境下，使用外放模式听音乐时，可以使得扬声器所播放的低频成分减弱。这样，既不影响这些环境场景下的使用体验（因为本来在该场景下也无法有效听到扬声器发出来的低频声音），又可以在很大程度上避免无谓的功率消耗。图6的环境噪声中的低频噪声频谱可为步骤104中生成的环境状态结果。
本申请实施例中，图7为本申请实施例提供的一种扬声器的功耗控制方法的应用示意图，通过对比将图6中的环境噪声中的低频噪声频谱与图4中的微型扬声器典型频响曲线放在一起，可以很容易地看出，微型扬声器的低频输出很容易被环境噪声中的低频成本掩蔽，从而使得微型扬声器发出的低频声音无法被听到。
本申请实施例提供的技术方案中，通过环境信息采集设备获取环境状态信息；通过环境状态分析模块对环境状态信息进行分析，生成环境状态结果；接收用户输入的模式选择结果；通过功耗参数计算模块根据环境状态结果和模式选择结果，生成功耗控制参数；通过功耗抑制模块根据功耗控制参数对扬声器进行功耗控制。本申请实施例提供的技术方案中，通过功耗参数计算模块根据环境状态结果和模式选择结果，生成功耗控制参数并通过功耗抑制模块根据功耗控制参数对扬声器进行功耗控制，可以动态地控制扬声器的功耗，以更进一步地对功耗进行节约。
