具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种音频输出控制方法。参照图1，图1为本发明音频输出控制方法第一实施例的流程示意图。
在本实施例中，音频输出控制方法应用于一电子装置中，该音频输出控制方法包括：
步骤S10，在电子装置接收到应用切换指令时，获取所述切换指令对应的待切换多媒体应用；
其中，电子装置包括智能电视、IPAD等，智能电视的多媒体应用包括天籁K歌、爱奇艺视频等视频、音乐应用以及HDMI (High
Definition Multimedia
Interface，高清晰度多媒体接口)应用、DTV应用等。智能电视多媒体应用的切换指令是指用户在需要切换多媒体应用时通过遥控器等终端或者电视的面板等发送的指令，在接收到用户通过遥控器等终端或者电视的面板发送或输入的切换指令时，电视获取该切换指令对应的待切换多媒体应用，该待切换多媒体应用可以为智能电视中除当前多媒体应用之外的任一多媒体应用。
步骤S20，获取所述待切换多媒体应用与当前多媒体应用之间的切换时长，其中，所述切换时长大于当前多媒体应用的关闭时长；
切换时长是指待切换多媒体应用与当前多媒体应用进行切换时电视系统所需要消耗的时间。容易理解，切换时长主要包括待切换多媒体应用的启动时长与当前多媒体应用的关闭时长（内存释放时长），而多媒体应用的内存释放时长以及启动时长由该多媒体应用的内存大小决定，因此，电视终端的不同多媒体应用之间的切换时长主要由待切换多媒体应用及当前多媒体应用的内存大小决定。本实施例中，通过分别获取待切换多媒体应用与当前多媒体应用的内存大小，然后根据获取到的待切换多媒体应用与当前多媒体应用的内存大小分别计算待切换多媒体应用与当前多媒体应用的关闭时长（耗时），再将计算得到的待切换多媒体应用的启动时长与当前多媒体应用的关闭时长相加即可得到待切换多媒体应用与当前多媒体应用之间的切换时长，例如，当前多媒体应用天籁K歌所占用的内存大小为1200M，则当前多媒体应用的关闭时长为1200ms，待切换多媒体应用DTV多媒体应用的内存大小为1000M，则待切换多媒体应用的启动时长为1000ms，因此，该待切换多媒体应用与当前多媒体应用之间的切换时长为2200ms，多媒体应用的内存大小每增加100M则其对应的切换时长增加100ms。当然，在当前多媒体应用与待切换多媒体应用不是第一次切换时，可以获取电视系统存储的当前多媒体应用与待切换多媒体应用的启动时长，该切换时长为当前多媒体应用与待切换多媒体应用的前一次切换的切换时长，其中前一次的多媒体应用切换可以为由当前多媒体应用切换至待切换多媒体应用或者由待切换多媒体应用切换至当前多媒体应用。
步骤S30，将所述电子装置的音频功率放大器的音频输出状态调整为静音状态，且所述静音状态的持续时长为所述切换时长；
本实施例中，通过将电视的音频功率放大器处于高电平使音频功率放大器的音频输出状态调整为静音状态，电视的音频功率放大器为高电平中断的功率放大器，且音频功率放大器处于高电平的持续时间为待切换多媒体应用与当前多媒体应用的关闭时长。
步骤S40，在所述静音状态结束时，恢复所述音频功率放大器的音频输出状态。
在静音状态的持续时间结束时，电视恢复音频功率放大器的音频输出状态，即将音频功率放大器的音频输出调整为多媒体应用切换前的音频输出状态，将音频功率放大器的音频输出增益调整为多媒体应用切换前的音频输出增益。
本实施例中，在恢复音频功率放大器的音频输出时，获取本次待切换多媒体应用与当前多媒体应用的关闭时长，然后存储或者更新待切换多媒体应用与当前多媒体应用的关闭时长，以供后续再次进行待切换多媒体应用与当前多媒体应用的切换时，直接采用本次切换的切换时长。
在切换过程中，可以通过电视系统的显示模块显示当前多媒体应用切换的信息，譬如切换过程中音频输出的信息，音频输出增益的调节过程信息及音频输出增益的变化信息等。
本实施例通过在电子装置接收到应用切换指令时，获取所述切换指令对应的待切换多媒体应用，接着获取待切换多媒体应用与当前多媒体应用之间的切换时长，然后将电子装置的音频功率放大器的音频输出状态调整为静音状态，且静音状态的持续时长为切换时长，最后在静音状态结束时，恢复音频功率放大器的音频输出状态，实现了在多媒体应用切换过程中使得电视音频功率放大器的音频输出为静音输出，能够避免多媒体应用切换过程中输出当前多媒体应用的音频信息、甚至用户听到刺耳的声音等现象，进而避免多媒体应用切换时当前多媒体应用的噪音等音频输出异常，提高了用户体验。
基于第一实施例提出本发明音频输出控制方法的第二实施例，参照图2，在本实施例中，步骤S20包括：
步骤S21，在所述待切换多媒体应用与当前多媒体应用之间是第一次切换时，分别获取所述待切换多媒体应用与当前多媒体应用占用的内存大小；
待切换多媒体应用与当前多媒体应用占用的内存大小是指待切换多媒体应用与当前多媒体应用在运行过程中分别占用的电视系统内存的大小。
步骤S22，分别基于获取的所述待切换多媒体应用与当前多媒体应用占用的内存大小计算所述待切换多媒体应用的启动时长及当前多媒体应用的关闭时长；
根据获取到的待切换多媒体应用与当前多媒体应用的内存大小分别计算待切换多媒体应用的启动时长与当前多媒体应用的关闭时长，例如，当前多媒体应用天籁K歌所占用的内存大小为1200M，则当前多媒体应用的关闭时长为1200ms，待切换多媒体应用DTV多媒体应用的内存大小为1000M，则待切换多媒体应用的启动时长为1000ms，本实施例中，待切换多媒体应用或当前多媒体应用的内存大小每增加100M则其对应的切换时长增加100ms。
步骤S23，将所述待切换多媒体应用的启动时长与当前多媒体应用的关闭时长相加获得所述待切换多媒体应用与当前多媒体应用之间的切换时长，并保存获得的所述切换时长。
将上述待切换多媒体应用的启动时长以及当前多媒体应用的关闭时长相加即可得到待切换多媒体应用与当前多媒体应用之间的切换时长，譬如，当前多媒体应用的关闭时长为1200ms，待切换多媒体应用的启动时长为1000ms时，待切换多媒体应用与当前多媒体应用之间的切换时长为2200ms。本实施例中，随着多媒体应用的不断更新，该多媒体应用所占用的内存可能变大（多媒体应用优化）或变小（多媒体应用的功能增加时）进而造成该多媒体应用与其他多媒体应用的切换时长发生变化，因此，在每次多媒体应用之间的切换时长计算完成后，可以存储或更新系统存储的切换时长。
本实施例通过在待切换多媒体应用与当前多媒体应用之间是第一次切换时，分别获取待切换多媒体应用与当前多媒体应用占用的内存大小，接着分别基于获取的待切换多媒体应用与当前多媒体应用占用的内存大小计算待切换多媒体应用的启动时长及当前多媒体应用的关闭时长，然后将待切换多媒体应用的启动时长与当前多媒体应用的关闭时长相加获得待切换多媒体应用与当前多媒体应用之间的切换时长，并保存获得的切换时长，实现了根据待切换多媒体应用与当前多媒体应用的内存大小计算待切换多媒体应用与当前多媒体应用之间的切换时长，使得待切换多媒体应用与当前多媒体应用之间的切换时长的计算更准确，进而能够精确的避免多媒体应用切换时声音异常的问题发生，进一步提高了用户体验。
基于第一实施例提出本发明音频输出控制方法的第三实施例，参照图3，在本实施例中，在步骤S40之后，该音频输出控制方法还包括：
步骤S50，在所述待切换多媒体应用与当前多媒体应用切换完成时，获取所述待切换多媒体应用与当前多媒体应用的实际切换时长；
本实施例中，在每次进行多媒体应用切换时，电视系统存储该多媒体应用切换的切换时长以及对应的多媒体应用（包括待切换多媒体应用以及当前多媒体应用的信息），当然在电视系统存储有该多媒体应用切换的切换时长时，直接更新该切换时长，以使得该切换时长更加准确，譬如随着多媒体应用的不断更新，该多媒体应用所占用的内存可能变大（多媒体应用优化）或变小（多媒体应用的功能增加时）进而造成该多媒体应用与其他多媒体应用的切换时长发生变化，因此，在每次多媒体应用切换完成后，都需要更新系统存储的切换时长，因此在待切换多媒体应用与当前多媒体应用切换完成时，需要获取待切换多媒体应用与当前多媒体应用的实际切换时长。
步骤S60，存储所述实际切换时长或基于所述实际切换时长更新所述切换时长；
进一步地，在其他实施例中，该步骤S20还包括：在所述待切换多媒体应用与当前多媒体应用之间不是第一次切换时，获取所述电视存储的所述待切换多媒体应用与当前多媒体应用之间的切换时长。
在待切换多媒体应用与当前多媒体应用之间不是第一次切换时，电视系统内存有待切换多媒体应用与当前多媒体应用最后一次切换的切换时长，因此可以直接获取电视存储的所述待切换多媒体应用与当前多媒体应用之间的切换时长。
本实施例中，通过在待切换多媒体应用与当前多媒体应用切换完成时，获取待切换多媒体应用与当前多媒体应用的实际切换时长，然后存储实际切换时长或基于实际切换时长更新所述切换时长，实现了待切换多媒体应用与当前多媒体应用之间的实际切换时长的存储或更新，进而为后续再次进行该待切换多媒体应用与当前多媒体应用之间的切换时，直接调用该切换时长，提高了待切换多媒体应用与当前多媒体应用的切换效率，使得切换时电视系统音频输出的控制更加准确。
基于第一实施例提出本发明音频输出控制方法的第四实施例，在本实施例中，该音频输出控制方法还包括：
在所述音频功率放大器处于静音状态时，递减所述音频功率放大器的音频输出增益；
其中，递减当前电视的音频输出增益可以采用定时等分递减的方式，其中定时的时间间隔可以根据切换时长以及等分的次数确定，譬如每隔100ms递减一次，本实施例中，直至在所述音频功率放大器静音状态的持续时长内音频输出增益递减至零DB为止。
在步骤S40之后，该音频输出控制方法还包括：递增所述音频功率放大器的音频输出增益。
本实施例中，可以采用与上述递减当前电视的音频输出增益的方式相反的方式进行递增电视的音频输出增益，即采用定时等分递增的方式，其中，定时的时间间隔可以根据切换时长以及等分的次数确定，譬如每隔100ms递减一次，递增的增益大小与上述递减的增益大小相同，本实施例中，通过递增音频功率放大器的音频输出增益，知道电视系统音频功率放大器的音频输出增益达到多媒体应用切换前音频功率放大器的音频输出增益。
本实施例通过在音频功率放大器处于静音状态时，递减音频功率放大器的音频输出增益，减少了电视音频输出的噪音干扰，并使音频输出的增益持续平滑的衰减，为用户提供优质的听觉感受，通过递增音频功率放大器的音频输出增益，使得在播放待切换多媒体应用时电视系统的音频输出增益平滑的增大，减少了电视音频输出的噪音干扰以及避免了在播放待切换多媒体应用时出现刺耳的声音，进一步提高了用户体验。
本发明进一步提供一种音频输出控制装置。参照图4，图4为本发明音频输出控制装置第一实施例的功能模块示意图。
在本实施例中，该声音处理异常装置包括：

其中，电子装置包括智能电视、IPAD等，例如智能电视的多媒体应用包括天籁K歌、爱奇艺视频等视频、音乐应用以及HDMI (High

第二获取模块20，用于获取所述待切换多媒体应用与当前多媒体应用之间的切换时长，其中，所述切换时长大于当前多媒体应用的关闭时长；
切换时长是指待切换多媒体应用与当前多媒体应用进行切换时电视系统所需要消耗的时间。容易理解，切换时长主要包括当前多媒体应用的（关闭时长）内存释放时长以及待切换多媒体应用的启动时长，而多媒体应用的内存释放时长以及启动时长由该多媒体应用的内存大小决定，因此，电视终端的不同多媒体应用之间的切换时长主要由待切换多媒体应用及当前多媒体应用的内存大小决定。本实施例中，通过分别获取待切换多媒体应用与当前多媒体应用的内存大小，然后根据获取到的待切换多媒体应用与当前多媒体应用的内存大小分别计算待切换多媒体应用与当前多媒体应用的关闭时长（耗时），再将计算得到的待切换多媒体应用的启动时长与当前多媒体应用的关闭时长相加即可得到待切换多媒体应用与当前多媒体应用之间的切换时长，例如，当前多媒体应用天籁K歌所占用的内存大小为1200M，则当前多媒体应用的关闭时长为1200ms，待切换多媒体应用DTV多媒体应用的内存大小为1000M，则待切换多媒体应用的启动时长为1000ms，因此，该待切换多媒体应用与当前多媒体应用之间的切换时长为2200ms，多媒体应用的内存大小每增加100M则其对应的切换时长增加100ms。当然，在当前多媒体应用与待切换多媒体应用不是第一次切换时，可以获取电视系统存储的当前多媒体应用与待切换多媒体应用的启动时长，该切换时长为当前多媒体应用与待切换多媒体应用的前一次切换的切换时长，其中前一次的多媒体应用切换可以为由当前多媒体应用切换至待切换多媒体应用或者由待切换多媒体应用切换至当前多媒体应用。

本实施例中，通过静音模块30将电视的音频功率放大器处于高电平使音频功率放大器的音频输出状态调整为静音状态，电视的音频功率放大器为高电平中断的功率放大器，且音频功率放大器处于高电平的持续时间为待切换多媒体应用与当前多媒体应用的关闭时长。
恢复模块40，用于在所述静音状态结束时，恢复所述音频功率放大器的音频输出状态。
在静音状态的持续时间结束时，恢复模块40恢复音频功率放大器的音频输出，即将音频功率放大器的音频输出调整为多媒体应用切换前的音频输出状态，将音频功率放大器的音频输出增益调整为多媒体应用切换前的音频输出增益。

递减模块70，用于在所述音频功率放大器处于静音状态时，递减所述音频功率放大器的音频输出增益；
其中，递减当前电视的音频输出增益可以采用定时等分递减的方式，其中定时的时间间隔可以根据切换时长以及等分的次数确定，譬如每隔100ms递减一次，本实施例中，直至在所述音频功率放大器静音状态的持续时长内音频输出增益递减至零DB为止。
递增模块80，用于递增所述音频功率放大器的音频输出增益。
本实施例中，可以采用与上述递减当前电视的音频输出增益的方式相反的方式进行递增电视的音频输出增益，即采用定时等分递增的方式，其中，定时的时间间隔可以根据切换时长以及等分的次数确定，譬如每隔100ms递减一次，递增的增益大小与上述递减的增益大小相同，本实施例中，通过递增音频功率放大器的音频输出增益，知道电视系统音频功率放大器的音频输出增益达到多媒体应用切换前音频功率放大器的音频输出增益。
本实施例通过在音频功率放大器处于静音状态时，递减模块70递减音频功率放大器的音频输出增益，减少了电视音频输出的噪音干扰，并使音频输出的增益持续平滑的衰减，为用户提供优质的听觉感受，通过递增模块80递增音频功率放大器的音频输出增益，使得在播放待切换多媒体应用时电视系统的音频输出增益平滑的增大，减少了电视音频输出的噪音干扰以及避免了在播放待切换多媒体应用时出现刺耳的声音，进一步提高了用户体验。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
