参阅图1，为符合本发明一优选实施例中用于智能终端的声音控制方法的流程示意图，所述声音控制方法包括以下步骤：
S101：于所述智能终端内预设至少一个运行时长不超过一预设于所述智能终端内的 第一时间阈值的特效音频。
所述智能终端，可以是智能手机、平板电脑、多媒体播放器等具备音频播放功能的智能设备，可以播放提示音、音乐、视频声音等音频信号。所述智能终端内预设至少一个特效音频，所述特效音频是指可以播放特殊声音效果的音频文件，例如播放鼓声、钢琴声、鼓掌声、打碟音等具有鲜明特色的声音特效。所述特效音频存储于所述智能终端的存储介质中，且每一特效音频播放的运行时长受到限制，即不超过一预设于所述智能终端内的第一时间阈值。所述第一时间阈值优选为最多5秒钟。所述特效音频的运行时长，也就是播放时间如果太长，会影响原本正在播放的音乐的听觉效果，有画蛇添足的感觉。所述特效音频预设好以后以备后续步骤中播放。所述特效音频为所述智能终端可识别的格式，如MP3格式、WMA格式等。
S102：所述智能终端运行一包含音乐的音频文件。
本步骤运行一音频文件，所述音频文件是一种多媒体文件，含有声音信息，例如讲话录音、歌曲、乐器演奏等。常见的音频文件格式有AU格式、AIFF格式、VQF格式、CD格式、APE格式、MP3格式、RealAudio格式、WMA格式、MIDI格式、WAV格式。本实施例中，所述音频文件的格式应当为数字格式，能够被所述智能终端识别并打开运行，例如MP3格式、WMA格式等。所述音频文件的内容也有要求，须包含音乐，例如歌曲、乐器演奏或者其他形式的旋律。本步骤运行所述音频文件后，所述音频文件持续运行，持续至后续的所有步骤完成。
S103：判断所述智能终端是否接收一点击操作或滑动触摸操作。
本步骤中，判断所述智能终端是否接收到外部操作，所述外部操作为点击操作或滑动触摸操作。对于具有触摸屏的智能终端，用户与所述触摸屏接触一次很快分开的操作即为点击操作，本实施例对于点击操作发生的位置不作限制，在所述触摸屏上任一位置进行点击操作都是有效的。所述滑动触摸操作即用户在所述触摸屏上接触后持续滑动一段距离，而后才脱离与触摸屏的接触。所述滑动操作在所述触摸屏上留有滑动轨迹，所述滑动轨迹的起始位置与终止位置的距离应当不小于100个像素点。所述智能终端获取所述滑动操作起始位置与终止位置的像素点坐标，而后计算其距离即可。所述起始位置和终止位置可通过被检测的时间先后判定，最先检测到的位置必然是起始位置，最后一个检测到的位置为终止位置。本步骤中所述智能终端接收所述点击操作或者滑动触摸操作中的任一种均视为判断有效。
S104：当所述智能终端接收所述点击操作或滑动触摸操作时，则运行所述音频文件 的同时，随机播放任一所述特效音频。
当步骤S103判断所述智能终端接收了所述点击操作或滑动操作时，执行本步骤。本步骤执行的另一条件为所述音频文件仍在运行，判断方法是从所述智能终端的任务管理器中获取正在运行的线程的状态，判断所述视频文件的进程是否在运行即可。本步骤执行内容为随机播放任一所述特效音频，例如所述智能终端内预存有特效音频A、特效音频B和特效音频C，则随机选取这三个特效音频中的一个进行播放。播放所述特效音频时，所述音频文件的运行正常进行，不中断。
在本申请第一方面的某些实施方式中，所述智能终端运行一包含音乐的音频文件时，使用所述智能终端内的第一声道；随机播放任一所述特效音频时，使用所述智能终端内的第二声道。本优选实施例对所述智能终端运行音频文件及播放特效音频的实现作了优选。对于同一个扬声器，理论上同时只能同时播放一个声音信号，若在运行所述音频文件的同时播放所述特效音频，会发生冲突，需要解决这个矛盾。本实施例的解决方案是采用不同的声道分别播放所述音频文件和特效音频。声道(Sound Channel)是指声音在录制或播放时在不同空间位置采集或回放的相互独立的音频信号，所以声道数也就是声音录制时的音源数量或回放时相应的扬声器数量。本实施例中所述智能终端包括至少两个声道，即第一声道和第二声道。两个声道的软硬件独立，有各自的扬声器、功放电路及解码器，从而实现分别播放两个音频。用户会同时听到两个声道发出的声音，即正常播放的音乐和对应用户操作而播放的特效声音。
在本申请第一方面的某些实施方式中，随机播放任一所述特效音频时，将所述音频文件与所述特效音频混音后播放。本实施例采用混音的方式解决两个音频同时播放的问题。混音是音乐制作中的一个常见步骤，也会缩写成MIX，是把多种来源的声音，整合至一个立体音轨(Stereo)或单音音轨(Mono)中。混音既可以通过硬件实现，也可以通过软件实现，实现混音装置的名称为混音器。软件类型的混音器，是将多个音频文件、线路输入音频信号混音后，合成单独的音频文件。本实施例中，先通过解码器将两个或以上的音频文件中的音频数据解码后变为两个或以上模拟信号，然后通过混音器对两个或以上模拟信号进行叠加，变为一个模拟信号，最后将该模拟信号输出播放。在其他实施方式中，也可以将叠加后的模拟信号通过编码器编码为数字音频格式，重新形成一个合并后的音频文件。
参阅图2，为符合本发明一优选实施例中图1中步骤S104的具体流程示意图，本实施例中，步骤S101中所述特效音频至少为两个，作为所述步骤S104执行的基础。所述 步骤S104包括：
S104-1：判断在一预设于所述智能终端的第二时间阈值内，所述智能终端是否接收所述点击操作和滑动触摸操作各一次。
本步骤判断在所述第二时间阈值内，所述智能终端是否接收所述点击操作和滑动触摸操作各一次。即用户在所述第二时间阈值内分别进行了点击操作和滑动触摸操作。所述第二时间阈值优选为最长1分钟，若所述第二时间阈值过长，则两次操作的判断周期过长，体现不出不同的特效音频的差异性效果。本步骤执行时，无论用户进行了点击操作或者滑动触摸操作，所述智能终端均开始计时，当用户进行与上一次操作种类不同的操作时，结束计时，判断两次操作的间隔时间是否小于所述第二时间阈值，若小于，则本步骤判断成立。若用户的多次操作种类与第一次操作的种类相同，例如均为点击操作或均为滑动触摸操作，则从最后一次操作开始计时。
S104-2：若所述智能终端在所述第二时间阈值内接收所述点击操作和滑动触摸操作各一次，则针对所述点击操作和滑动触摸操作随机选择不同的特效音频进行播放。
若步骤S104-1判断成立，即所述智能终端在所述第二时间阈值内接收所述点击操作和滑动触摸操作各一次，则执行本步骤。本步骤的核心是所述点击操作和滑动触摸操作所对应的特效音频是不同的，以产生不同种类操作对应的差异性声音特效。在所述第二时间阈值内，第一次操作执行后，所述智能终端在所有特效音频中随机选择一个特效音频进行播放，并记录被播放的特效音频为第一特效音频；当所述第二时间阈值内发生另一种操作时，所述智能终端首先将所述第一特效音频排除，在剩余的特效音频中进行随机选择，而后播放被选择的特效音频。所述第二时间阈值内第二次播放特效音频后，所述智能终端解除第一特效音频的记录，以便下一次操作时继续在所有的特效音频中进行随机选取。例如所述智能终端内预存有特效音频A、特效音频B和特效音频C，当所述智能终端接收一点击操作时，则随机选取这三个特效音频中的一个进行播放，例如选择特效音频B播放，记录特效音频B为第一特效音频；而后在所述第二时间阈值内所述智能终端接收一滑动触摸操作，则在特效音频A和特效音频C中随机选取一个进行播放；播放完毕后解除对特效音频B的记录，下一次接收操作时仍从三个特效音频中随机选取。
S104-3：若所述智能终端在所述第二时间阈值内未接收所述点击操作和滑动触摸操作各一次，则针对所述点击操作和滑动触摸操作随机选择任一特效音频进行播放。
若步骤S104-1判断不成立，即所述智能终端在所述第二时间阈值内未接收所述点击操作和滑动触摸操作各一次，则执行本步骤。实际上所述步骤S104-1判断的是一种特殊 情况，即在所述第二时间阈值内接收不同种类的操作，而本步骤执行该特殊情况以外的以其他方式接收操作的情况。本步骤执行内容为随机选择任一特效音频进行播放，即从所有预存的特效音频中随机选取一个进行播放。例如所述智能终端接收两次操作的时间间隔大于所述第二时间阈值，则对应两次操作均随机选择一特效音频播放，每次随机选择都是独立的，互不影响。
参阅图3，为符合本发明另一优选实施例中图1中步骤S104的具体流程示意图，本实施例是对步骤S104采用混音方式情况下的具体步骤说明，所述步骤S104包括：
S104-4：提取所述特效音频并解码，得到一第一解码文件。
本步骤随机选择一特效音频后对所述特效音频进行解码。对于智能终端而言，其内部存储的特效音频及音频文件均为数字格式，即所述特效音频及音频文件内存储的不是直接表征声音信号的模拟信号，而是将所述模拟信号按照编码规则压缩后的数字信息，如果想要播放该特效音频，需要首先对所述特效音频进行解码，将其还原为模拟信号。本步骤即进行解码过程，将所述特效音频解码得到一包括模拟信号的第一解码文件。
S104-5：提取所述音频文件中与所述特效音频播放时间相同的片段并解码，得到一第二解码文件。
本步骤与步骤S104-4执行内容相似，也是解码操作，执行的对象为所述音频文件中与所述特效音频播放时间相同的片段。由于所述特效音频的播放时间小于所述第一时间阈值，正常情况下一首歌为3分钟左右，所述特效音频也就远远小于所述音频文件的播放时间，因此同步播放所述特效音频与音频文件时，只需要在同步播放的时间进行混音即可，故只需对所述音频文件中的与所述特效音频播放时间相同的片段进行解码。所述特效音频的文件中会记录该特效音频的播放时长，这是可读属性，而后在准备开始播放所述特效音频时获取所述音频文件的播放进度，再向后累加所述特效音频的播放时间，再做剪切即可得到所述音频文件的片段，最后进行解码即可得到所述第二解码文件。
S104-6：将所述第一解码文件和第二解码文件进行叠加，得到一第三解码文件。
本步骤将所述步骤S104-4和S104-5分别得到的第一解码文件和第二解码文件进行叠加。所述第一解码文件和第二解码文件记载的都是模拟信号信息，在同一时间刻度上对两个模拟信号的幅度进行求和即可，最后得到新的模拟信号信息，存储为第三解码文件。
S104-7：播放所述第三解码文件。
本步骤对所述第三解码文件执行播放操作，由于所述第三解码文件已经是模拟信号， 故可由硬件进行输出，再由功放电路进行放大后输出给扬声器即可。本步骤执行结束后，即所述特效音频的播放时长达到后，所述智能终端恢复对所述音频文件的正常播放，结束混音播放方式。
