 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，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，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例提供一种音频播放方法、装置、存储介质及移动终端。
如图1所示，图1是本申请实施例提供的音频播放方法的流程示意图，该音频播放方法应用于移动终端，该移动终端包括主扬声器和辅助扬声器，该移动终端可以包括智能手机、平板电脑、IPAD等设备，具体流程可以如下：
S101. 当检测到待播放的音频信号时，将该音频信号存储在预设缓存区，同时向该辅助扬声器传输该音频信号，以使该辅助扬声器播放该音频信号。
其中，该预设缓存区可以是移动终端中可用于数据存储的任意区域，比如Framework（框架）层，HAL（Hardware Abstraction Layer，硬件抽象层）,或ADSP（数字信号处理芯片）中的任意区域。该待播放的音频信号可以是歌曲、视频里的音频、聊天软件中的语音等，比如，请参见图2，当用户打开音乐播放应用，并点击“泡沫”这首歌的播放按键时，可以将“泡沫”这首歌作为待播放的音频信号，此时，音频信号会同时按照两条线路进行传输，一条线路是传输到预设缓存区，经过预设缓存区传输到主扬声器A进行播放，另一条线路是直接传输到辅助扬声器B进行播放。
S102. 在该音频信号的存储过程中，启动计时器开始计时。
其中，由于音频信号通常是一段信号流，故音频信号在预设缓存区的存储操作需消耗一定时间，移动终端可以一边执行音频信号的存储操作，一边进行计时。
S103. 当计时时长到达预设延迟时长时，从该预设缓存区中获取该音频信号传输至该主扬声器，以使该主扬声器播放该音频信号。
需要说明的是，为得到较好的立体声效果，主扬声器和辅助扬声器之间音量差越大，预设延迟时长可以越长，这主要是基于人类对声音定位的感知原理来设计的思路。具体的，人类感知声音位置的一个重要因素是右耳所听声音和左耳所听声音之间的差异，这种差异的造成因素可以包括两耳间水平差和两耳间时间差，其中，两耳间水平差是指用户所感知到的两只耳朵所听到声音的大小差，两耳间时间差是指用户所感知到的声音到达两只耳朵的时间差，举个例子，枪声从右边传来，因为声音是以声波的形式传播，故它首先是到达你的右耳，然后才是左耳，声音到达两只耳朵的时间差会让用户感知枪声是在右边传来。另外，由于声波的自然消散、以及人头部对声音造成的吸收和反射等波消耗，故到达左耳时的声音比右耳更弱，两只耳朵的声音大小差也会让用户感知枪声是从右边传来，基于上述感知原理，我们可以通过刻意制造声音时间差来克服双扬声器中由于结构差异造成的左右声音大小不一致引起用户人耳听起来偏向某一个扬声器的问题。
其中，预设延迟时长是人为设定的，比如20ms，一般建议不大于25ms，避免时间过长导致用户会听出延迟效果。预设延迟时长通常是基于主扬声器和辅助扬声器的发生元件尺寸、功率、以及音腔结构等影响音量大小的客观因素来设计的。
例如，该音频播放方法还可以包括：
确定该辅助扬声器的第一播放音量和该主扬声器的第二播放音量之间的差值；
根据该差值确定该预设延迟时长。
其中，该预设延迟时长可以是计算出来的，开发人员可以提前基于扬声器发声元件的尺寸、功率设计一个音量差的计算公式，该计算公式中的参数可以根据尺寸和功率的变化自适应调整，后续扬声器若发生故障进行更换，终端可以检测更换后的扬声器的功率（比如通过扬声器的线圈电流确定功率）和尺寸对音量差进行更新，而预设延迟时长可以和音量差成正比例变化。
在其他实施方式中，该预设延迟时长可以是提前设定好的固定值，此时，上述步骤“根据该差值确定该预设延迟时长”具体可以包括：
确定所述差值对应的预设差值范围；
获取所述预设差值范围对应的预设时长，作为预设延迟时长。
其中，开发人员可以提前在移动终端中设置多个预设差值范围、以及每个预设差值范围对应的预设时长，将它们关联存储，之后，实际应用时，可以直接找到当前移动终端主副扬声器的音量差对应的预设差值范围，进而匹配到合适的预设时长作为预设延迟时长。
除了终端自身可以对预设延迟时长进行调整之外，用户也可以对预设延迟时长进行调整，比如当用户明显感觉到左右耳音量失衡时，可以主动触发进行调整，也即，请参见图3，该音频播放方法还可以包括下述步骤S104-S106，其中：
S104. 生成音效校正指令。
具体的，可以在显示界面上生成一个专用按键，为用户提供音效校正功能，其中，终端可以在当前前台显示音频播放页面，或者视频播放页面的时候，触发生成专用按键，当用户点击该专用按键时，生成音效校正指令。
S105. 根据该音效校正指令在该移动终端的显示屏中显示校正界面，该校正界面包括左声道栏、右声道栏、位于该左声道栏上的第一调节块、以及位于该右声道栏上的第二调节块。
其中，请参见图4，左声道栏m1和右声道栏m2可以是长条状，其上可以有多个节点或刻度，可以分别对应辅助扬声器和主扬声器，通常情况下，初次显示的调节块（n1和n2）位于中点位置的节点或刻度处，当用户往左移动调节块时，可以认为用户想调小相应声道的音量，当用户往右移动调节块时，可以认为用户想调大相应声道的音量，调节块移动的幅度越大，相应声道的音量调节幅度也越大。调节块可以是任意形状，比如方形或者圆形等。
S106. 通过该校正界面获取该第一调节块和/或该第二调节块发生移动时的移动位置，并根据该移动位置更新该预设延迟时长。
其中，上述步骤“根据该移动位置更新该预设延迟时长”，具体包括：
根据该移动位置确定目标调节比例；
计算该目标调节比例和该预设延迟时长之间的乘积，得到更新后的预设延迟时长。
具体的，可以认为移动后，第一调节块和第二调节块在各自声道栏上的最终位置的比值，即为目标调节比例，比如理想立体音效情况下，第一调节块和第二调节块应当均位于中间节点处，也即比值为1，当第一调节块和/或第二调节块发生移动时，比值可能小于1或者大于1，小于1代表需要增大主扬声器的音量，也即减小预设延迟时长，大于1代表需要减小主扬声器的音量，也即增大预设延迟时长。
由上述可知，本实施例提供的音频播放方法，应用于包括主扬声器和辅助扬声器的移动终端，当检测到待播放的音频信号时，通过将该音频信号存储在预设缓存区，同时向该辅助扬声器传输该音频信号，以使该辅助扬声器播放该音频信号，之后，在该音频信号的存储过程中，启动计时器开始计时，当计时时长到达预设延迟时长时，从该预设缓存区中获取该音频信号传输至该主扬声器，以使该主扬声器播放该音频信号，从而能通过对主扬声器播放延迟的方式改善双扬声器结构中常见的大小喇叭现象，提升立体播放效果，且完全基于软件来实现，无需增加硬件，灵活性高，有利于减小终端成本。
在上述实施例的基础上，本实施例将从音频播放装置的角度进一步进行描述，请参阅图5，图5具体描述了本申请实施例提供的音频播放装置，其应用于移动终端，该移动终端包括主扬声器和辅助扬声器，该音频播放装置可以包括：第一传输模块10、计时模块20和第二传输模块30，其中：
（1）第一传输模块10
第一传输模块10，用于当检测到待播放的音频信号时，将该音频信号存储在预设缓存区，同时向该辅助扬声器传输该音频信号，以使该辅助扬声器播放该音频信号。

（3）第二传输模块30
第二传输模块30，用于当计时时长到达预设延迟时长时，从该预设缓存区中获取该音频信号传输至该主扬声器，以使该主扬声器播放该音频信号。
需要说明的是，为得到较好的立体声效果，主扬声器和辅助扬声器之间音量差越大，预设延迟时长可以越长，这主要是基于人类对声音定位的感知原理来设计的思路。具体的，人类感知声音位置的一个重要因素是右耳所听声音和左耳所听声音之间的差异，这种差异的造成因素可以包括两耳间水平差和两耳间时间差，其中，两耳间水平差是指用户所感知到的两只耳朵所听到声音的大小差，两耳间时间差是指用户所感知到的声音到达两只耳朵的时间差，举个例子，枪声从右边传来，因为声音是以声波的形式传播，故它首先是到达你的右耳，然后才是左耳，声音到达两只耳朵的时间差会让用户感知枪声是在右边传来。另外，由于声波的自然消散、以及人头部对声音造成的吸收和反射等波消耗，故到达左耳时的声音比右耳更弱，两只耳朵的声音大小差也会让用户感知枪声是从右边传来，基于上述感知原理，我们可以通过刻意制造声音时间差来克服双扬声器中由于结构差异造成的左右声音大小不一致引起用户人耳听起来偏向某一个扬声器的问题。
其中，预设延迟时长是人为设定的，比如20ms，一般建议不大于25ms，避免时间过长导致用户会听出延迟效果。预设延迟时长通常是基于主扬声器和辅助扬声器的发生元件尺寸、功率、以及音腔结构等影响音量大小的客观因素来设计的。例如，请参见图6，该音频播放装置还包括第一确定模块40，用于：
确定该辅助扬声器的第一播放音量和该主扬声器的第二播放音量之间的差值；
根据该差值确定该预设延迟时长。
其中，该预设延迟时长可以是计算出来的，开发人员可以提前基于扬声器发声元件的尺寸、功率设计一个音量差的计算公式，该计算公式中的参数可以根据尺寸和功率的变化自适应调整，后续扬声器若发生故障进行更换，终端可以检测更换后的扬声器的功率（比如通过扬声器的线圈电流确定功率）和尺寸对音量差进行更新，而预设延迟时长可以和音量差成正比例变化。

移动终端300还可包括至少一种传感器350，比如光传感器、运动传感器以及其他传感器。具体地，光传感器可包括环境光传感器及接近传感器，其中，环境光传感器可根据环境光线的明暗来调节显示面板341的亮度，接近传感器可在移动终端300移动到耳边时，关闭显示面板341和/或背光。作为运动传感器的一种，重力加速度传感器可检测各个方向上（一般为三轴）加速度的大小，静止时可检测出重力的大小及方向，可用于识别手机姿态的应用（比如横竖屏切换、相关游戏、磁力计姿态校准）、振动识别相关功能（比如计步器、敲击）等; 至于移动终端300还可配置的陀螺仪、气压计、湿度计、温度计、红外线传感器等其他传感器，在此不再赘述。
音频电路360、扬声器361，传声器362可提供用户与移动终端300之间的音频接口。音频电路360可将接收到的音频数据转换后的电信号，传输到扬声器361，由扬声器361转换为声音信号输出；另一方面，传声器362将收集的声音信号转换为电信号，由音频电路360接收后转换为音频数据，再将音频数据输出处理器380处理后，经RF电路310以发送给比如另一终端，或者将音频数据输出至存储器320以便进一步处理。音频电路360还可能包括耳塞插孔，以提供外设耳机与移动终端300的通信。
移动终端300通过传输模块370（例如Wi-Fi模块）可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图8示出了传输模块370，但是可以理解的是，其并不属于移动终端300的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
处理器380是移动终端300的控制中心，利用各种接口和线路连接整个手机的各个部分，通过运行或执行存储在存储器320内的软件程序和/或模块，以及调用存储在存储器320内的数据，执行移动终端300的各种功能和处理数据，从而对手机进行整体监控。可选的，处理器380可包括一个或多个处理核心；在一些实施例中，处理器380可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器380中。
移动终端300还包括给各个部件供电的电源390（比如电池），在一些实施例中，电源可以通过电源管理系统与处理器380逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。电源190还可以包括一个或一个以上的直流或交流电源、再充电系统、电源故障检测电路、电源转换器或者逆变器、电源状态指示器等任意组件。
尽管未示出，移动终端300还可以包括摄像头（如前置摄像头、后置摄像头）、蓝牙模块等，在此不再赘述。具体在本实施例中，移动终端的显示单元是触摸屏显示器，移动终端还包括有存储器，以及一个或者一个以上的程序，其中一个或者一个以上程序存储于存储器中，且经配置以由一个或者一个以上处理器执行一个或者一个以上程序包含用于进行以下操作的指令：

在该音频信号的存储过程中，启动计时器开始计时；
当计时时长到达预设延迟时长时，从该预设缓存区中获取该音频信号传输至该主扬声器，以使该主扬声器播放该音频信号。
具体实施时，以上各个模块可以作为独立的实体来实现，也可以进行任意组合，作为同一或若干个实体来实现，以上各个模块的具体实施可参见前面的方法实施例，在此不再赘述。
本领域普通技术人员可以理解，上述实施例的各种方法中的全部或部分步骤可以通过指令来完成，或通过指令控制相关的硬件来完成，该指令可以存储于一计算机可读存储介质中，并由处理器进行加载和执行。为此，本发明实施例提供一种存储介质，其中存储有多条指令，该指令能够被处理器进行加载，以执行本发明实施例所提供的任一种音频播放方法中的步骤。
