具体实施方式
下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例用于解释本发明，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。
图1是本发明实施例提供的一种音量调节方法的流程图，本实施例可适用于对终端设备播放音源时的音量进行调节的情况，该方法可以由本发明实施例提供的终端设备来执行，该终端设备的音量调节装置可采用软件和/或硬件的方式实现，如图1所示，本实施例提供的具体方案如下：
步骤S101、当检测到终端设备进行音源播放时，获取所述音源对应的第一音频信息。
终端设备可通过安装的第三方应用程序或系统自带的音视频播放软件进行音源的播放。其中，主要包括音源文件的获取、解码和输出等步骤。示例性的，获取到的音源文件可以是通过网络接收到的组播流，还可以是终端设备本地存储的音视频文件；获取到该音源文件后将其加载到内存缓冲区中；对加载到内存缓冲区的音源文件进行解码，在解码开始之前，如果该音源文件同时包含有视频数据，需要进行音频数据和视频数据的分离，将分离后的音频数据输入至音频解码器，其中，音频解码器主要用于读取内存缓冲区中的音频数据，得到数字音频信号，并将该数字音频信号转换为模拟音频信号，终端设备的播放器件根据该模拟音频信号进行音频播放。在一个实施例中，当监听到音源播放事件被触发时，确定终端设备开始播放音源，其中，该触发事件可以是检测到的触摸屏中显示的播放按钮被按下，还可以是检测到终端设备的播放器件如喇叭开始播放声音时，确定终端设备进行音源播放。
当检测到终端设备进行音源播放时，获取所述音源的第一音频信息。在一个实施例中，可对音频解码器解码得到的数字音频信号进行取样，确定该音源对应的第一音频信息。在另一实施例中，还可以获取当前播放的音源的原始文件，通过对该原始文件的解析确定音源对应的第一音频信息。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源对应的第一音频信息。
其中，该第一音频信息可以是一个音源对应的全部音频信息，示例性的，当检测到终端设备播放的音源为一歌曲时，该歌曲对应的音频信息可以作为第一音频信息，此时，相应的后续出现的第二音频信息为另一音源(如电影、聊天语音)对应的音频信息。该第一音频信息还可以是一个音源体系中包含的多个音频信息中的一个，可以是当前播放的音频信息作为第一音频信息，示例性的，当用户使用微信进行语音聊天时，用户可和联系人进行语音聊天交互，即可以间断的，在不同的时间发送语音信息，此时每个间断的语音信息可被认定为一个音频信息。
步骤S102、确定所述第一音频信息的第一音频振幅，如果所述第一音频振幅满足预设查询条件，则确定第二音频信息的第二音频振幅。
其中，所述第二音频信息为在所述第一音频信息之后播放的内容。
振幅指物体震动过程中偏离原来位置的最大距离，人耳听到的声音的响度 与音源的振幅相关，振幅越大响度越强。在一个实施例中，可通过音频解码器对获取的音频信息进行解码得到的数字音频信号后进行取样，以得到预设时间段T内的振幅信息，其中，该振幅信息可由多个振幅值组成，依据得到的多个振幅值可相应的确定在该预设时间段T内播放的音源的振幅曲线，即确定出和第一音频信息对应的第一音频振幅。在另一实施例中，以Android系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类对获取的第一音频信息进行振幅提取，得到对应的第一音频振幅。在另一实施例中，当步骤S101获取到的音频信息为音源对应的原始文件时，可通过对原始文件进行解析以得到对应的第一音频振幅。
在一个实施例中，当检测音源播放时，每隔预设时间(如1s、3s或10s)确定一次第一音频振幅，或者实时的，对音频信息的每一帧的振幅进行确定以得到第一音频振幅。示例性的，当检测到音源播放时，对音源文件进行解析得到第一音频帧序列，根据第一音频帧序列的每一帧确定对应的第一音频振幅。
相应的，确定第二音频振幅的方式参照第一音频振幅的确定方式，此处不再赘述。
在一个实施例中，所述第一音频振幅满足预设查询条件包括：所述第一音频振幅的振幅调节系数小于预设调节系数，或所述第一音频振幅的大小大于第一预设振幅阈值。示例性的，该预设调节系数可以是1.2或0.8，第一预设振幅阈值可以是-5db。其中振幅调节系数用于对音频振幅进行调节，示例性的，当音频振幅较小时可分配以振幅调节系数以使其振幅增大，进而提高音量，相应的，当音频振幅较大时也可通过分配小于1的振幅调整系数另该音频振幅减小以减小播放时的音量。
步骤S103、如果所述第二音频振幅满足预设调节条件，则确定对应的调节信息，依据所述调节信息对所述终端设备的音量进行调节。
所述第二音频振幅满足预设调节条件包括：所述第二音频振幅的大小小于第二预设振幅阈值。示例性的，该第二预设振幅阈值可以是-20db。在一个实施例中，所述第二音频振幅的大小小于第二预设振幅阈值包括：所述第二音频振幅的振幅峰值小于第二预设振幅阈值，或所述第二音频振幅的平均振幅值小于第二预设振幅阈值。
在一个可能的实施例中，如图2所示，图2是本发明实施例提供的一种音 源中第一音频振幅和第二音频振幅对应的振幅曲线示意图。其中，第一音频振幅较大，峰值为-3db，第二音频振幅的峰值为-30db，此时，如果按照预先分配的振幅调节系数(为了保持音源输出是的音量不至于过大或过小，其音源中振幅较大部分对应的振幅调节系数较小，振幅较小部分对应的振幅调节系数较大，例如：第一音频振幅对应的振幅调节系数为1，第二音频振幅对应的振幅调节系数为2)，当第一音频振幅播放完毕后，第二音频振幅由于先前第一音频振幅较大且分配有较小的振幅调整系数，则该第二音频振幅对应的调整系数无法起到调节作用。此时，确定对应的调节信息，依据所述调节信息对所述终端设备的音量进行调节，其中，可以是对终端设备的系统音量进行调节，还可以是对第二音频振幅进行调节，以提高第二音频信息输出时的音量。
由上述内容可知，当检测到第一音频信息的振幅较大，同时后续的第二音频信息的振幅较小时，对第二音频信息的振幅或终端的系统音量进行调节以提高第二音频信息输出的音量，避免了第二音频信息输出时音量较小，用户无法听清声音内容的问题，同时无需用户手动调节音量，提高了音量调节效率，听感也更加符合用户需求。
图3是本发明实施例提供的另一种音量调节方法的流程图，可选的，所述确定对应的调节信息，依据所述调节信息对所述终端设备的音量进行调节包括：确定对应的振幅调节信息，依据所述振幅调节信息对所述第二音频振幅进行调节。如图3所示，技术方案具体如下：
步骤S201、当检测到终端设备进行音源播放时，获取所述音源对应的第一音频信息。
步骤S202、确定所述第一音频信息的第一音频振幅，如果所述第一音频振幅满足预设查询条件，则确定第二音频信息的第二音频振幅。
步骤S203、如果所述第二音频振幅满足预设调节条件，则确定对应的振幅调节信息，依据所述振幅调节信息对所述第二音频振幅进行调节。
在一个实施例中，所述确定对应的振幅调节信息包括：依据所述第二音频振幅的大小以及振幅调节映射表确定对应的振幅调节信息。示例性的，一种振幅调节映射表中第二音频振幅的大小和对应的振幅调节系数关系如下：
表1
振幅大小 调节系数
-20db至-30db 1.7
-30db至-40db 1.8
-40db至50db 1.9
在一个实施例中，通过振幅调节系数对第二音频振幅进行调整的过程可以是：通过对相关的音源文件进行解析，对得到的音频信息中的表征振幅信息的数据进行修改，修改完毕后再进行封装，当缓冲到对应的音源文件并被播放时第二音频振幅相应的已被增大或减小；还可以是，在第二音频信息播放的解码过程中，通过对第二音频信息进行解码得到的数字音频信号进行分析得到第二音频振幅，将该第二音频振幅对应的振幅数据乘以对应的振幅调节系数以改变振幅大小，进而对其的音量进行调节。由此，实现了不改变终端设备系统原有音量的前提下对音源音量的大小进行了调节，调节过程可以在第二音频信息文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的第二音频信息内容进行调节以提高调节效率。
图4是本发明实施例提供的另一种音量调节方法的流程图，可选的，所述确定对应的调节信息，依据所述调节信息对所述终端设备的音量进行调节包括：确定对应的音量调节信息，依据所述音量调节信息对所述终端设备当前的系统音量进行调节。如图4所示，技术方案具体如下：
步骤S301、当检测到终端设备进行音源播放时，获取所述音源对应的第一音频信息。
步骤S302、确定所述第一音频信息的第一音频振幅，如果所述第一音频振幅满足预设查询条件，则确定第二音频信息的第二音频振幅。
步骤S303、如果所述第二音频振幅满足预设调节条件，则确定对应的音量调节信息，依据所述音量调节信息对所述终端设备当前的系统音量进行调节。
在一个实施例中，所述确定对应的音量调节信息，依据所述音量调节信息对所述终端设备当前的系统音量进行调节包括：确定对应的目标音量值或音量改变值，依据所述目标音量值或音量改变值对所述终端设备当前的系统音量进行调节。
在一个实施例中，该音量调节信息为对应的目标音量值。示例性的，终端 设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量增大信息对应的目标音量值可以是14或15，在对终端设备系统音量进行调节的过程中，相应的将音量值增大至14或15，可选的，在使用该音量的目标值进行音量调节之前，还包括：确定所述第二音频信息的播放时间，当播放时间大于预设时间时，如30s则采用依据所述音量调节信息中的目标音量值对所述终端设备的系统音量进行调节，由此进一步提高了音量调节效率，降低了终端设备的能耗。
在一个实施例中，该音量调节信息为对应的音量改变值。示例性的，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量改变值为3，例如，当前终端设备的音量值为10，当需要增大音量信息时，则在当前音量值的基础上增加3即采用第13级音量进行声音播放。可选的，在使用该音量改变值进行音量调节之前，还包括：确定所述第二音频信息的播放时间，当播放时间大于预设时间时，如30s则采用依据所述音量调节信息中的音量改变值对所述终端设备当前的音量值进行调节，由此进一步提高了音量调节效率，降低了终端设备的能耗。
图5是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述调节信息对所述终端设备的音量进行调节之前，还包括：确定所述终端设备播放器件的阻抗值，依据所述阻抗值对所述调节信息进行调整；相应的，所述依据所述调节信息对所述终端设备的音量进行调节包括：依据所述调整后的调节信息对所述终端设备的音量进行调节。
如图5所示，技术方案具体如下：
步骤S401、当检测到终端设备进行音源播放时，获取所述音源对应的第一音频信息。
步骤S402、确定所述第一音频信息的第一音频振幅，如果所述第一音频振幅满足预设查询条件，则确定第二音频信息的第二音频振幅。
步骤S403、如果所述第二音频振幅满足预设调节条件，则确定对应的音量调节信息。
步骤S404、确定所述终端设备播放器件的阻抗值，依据所述阻抗值对所述调节信息进行调整，依据所述调整后的调节信息对所述终端设备的音量进行调节。
在一个实施例中，可通过功放芯片检测终端设备中安装的播放器件(如：扬声器)的阻抗值，还可以是通过物理方式检测播放器件的阻抗。示例性的，该阻抗值越大对应的对音量调节信息的调整越大。具体的，假设播放器件的标称阻抗值为x，通过检测得到的阻抗值为1.2x，则相应的在确定出的调节信息的基础上，将该调节信息中对应的振幅调节信息、目标音量值或音量改变值乘以1.2作为调整后的调节信息。
由上述可知，在对音源的振幅进行调节过程中，引入播放器件的阻抗值作为确定音量调节信息的参量之一，避免了播放器件随播放时长的增加阻抗值越来越高进而对正常播放过程中的音量大小产生影响的问题，使得调节后的音量大小更佳符合用户需求，进一步提高了音量调节效果。
图6是本发明实施例提供的另一种音量调节方法的流程图，可选的，在所述依据所述调节信息对所述终端设备的音量进行调节之前，还包括：确定所述终端设备播所处环境的噪声值，依据所述噪声值对所述调节信息进行调整；相应的，所述依据所述调节信息对所述终端设备的音量进行调节包括：依据所述调整后的调节信息对所述终端设备的音量进行调节。
如图6所示，技术方案具体如下：
步骤S501、当检测到终端设备进行音源播放时，获取所述音源对应的第一音频信息。
步骤S502、确定所述第一音频信息的第一音频振幅，如果所述第一音频振幅满足预设查询条件，则确定第二音频信息的第二音频振幅。
步骤S503、如果所述第二音频振幅满足预设调节条件，则确定对应的音量调节信息。
步骤S504、确定所述终端设备所处环境的噪声值，依据所述噪声值对所述调节信息进行调整，依据所述调整后的调节信息对所述终端设备的音量进行调节。
在一个实施例中，可通过终端设备安装的麦克风采集当前所处环境的噪音以确定对应的噪声值。示例性的，该噪声值越大对应的对音量调节信息的调整越大。具体的，假设终端设备在安静环境下的噪声值为y，终端设备处于户外或嘈杂环境中时，确定的噪声值为1.5y，则相应的在确定出的调节信息的基础上，将该调节信息中的振幅调节信息、目标音量值或音量改变值乘以1.5作为 调整后的调节信息。需要说明的是，还可将阻抗值、噪声值共同调整调节信息。
由上述可知，在对音源的振幅进行调节过程中，考虑了噪声对终端设备音量的影响，将确定的噪声值作为确定音量调节信息的参量之一，使得调节后的音量大小更加符合用户需求，进一步提高了音量调节效果。
图7是本发明实施例提供的一种音量调节装置的结构框图，该装置用于执行上述实施例提供的音量调节方法，具备执行方法相应的功能模块和有益效果。如图7所示，该装置具体包括：获取模块101、振幅确定模块102、调节信息确定模块103和调节模块104。
