麦克风模块25，用于采集用户的声音或采集识别环境场景的环境音。例如，麦克风模块25可以采集用户的声音，从而主板23可以将该声音转换成语音控制指令，以实现控制显示设备200’的各种功能；麦克风模块25还可以采集环境音，从而主板23可以根据该环境音调整音频输出接口的输出音频，以实现显示设备200’自适应环境噪声。麦克风模块205可以对应于图3中的检测器230。
基于上述图3中显示设备200和图4中显示设备200’的配置框图，无需操作控制装置100也可以实现控制显示设备200。具体的，显示设备200可以直接通过图3中声音采集器231或图4中麦克风模块25采集用户发出的语音，进而将该语音转换成语音控制指令，以执行语音控制指令对应的功能。
例如，语音唤醒功能：当处于待机模式下的显示设备接收到用户发出的包含唤醒词的语音控制指令时，该显示设备便从待机模式中被唤醒而进入运行模式。
具体的，如图4所示，在显示设备处于待机模式下，麦克风模块25和MCU模块23b一直保持上电(处于开启状态)，而SOC模块23a保持掉电(处于关闭状态)；在显示设备处于运行模式下，麦克风模块25、MCU模块23b和SOC模块23a均保持上电(处 于开启状态)。
在此基础上，处于待机模式下的显示设备，麦克风模块25采集用户发出包含唤醒词的声音数据，并将声音数据传输至MCU模块23b；MCU模块23b接收该声音数据，经本地识别处理后识别出该声音数据中包含唤醒词，然后MCU模块23b根据该识别结果确定为唤醒显示设备的语音唤醒指令，并触发SOC模块23a进入工作状态，从而实现显示设备由待机模式被唤醒以进入运行模式。
又如，画面截图功能：当处于运行模式下的显示设备接收到用户发出的截图的语音控制指令时，其便对显示设备当前画面进行截图处理。
具体的，处于运行模式下的显示设备，麦克风模块25采集用户发出包含与截图相关关键词的声音数据，并将声音数据传输至MCU模块23b；MCU模块23b再将该声音数据传输至SOC模块23a；SOC模块23a通知语音和语义服务器对该声音数据进行语音识别和结果转换，并根据语音和语义服务器返回识别结果，将该识别结果确定为对显示设备显示的当前画面进行截图的语音控制指令，进而执行当前画面截图处理。
需要说明的是，待机模式下的显示设备中的大部分系统服务或全部系统服务处于关闭状态。例如待机模式下的显示设备中媒体输出功能的相关部件处于关闭状态，比如显示设备的音频输出为关闭状态，屏幕为不亮状态。且待机模式下，显示设备处于低功耗的工作状态，此时消耗的功率即为待机功耗。运行模式下的显示设备中的大部分系统服务或全部系统服务处于开启状态，其可正常工作。例如运行模式下的显示设备中媒体输出功能的相关部件处于开启状态，其音频输出为开启状态，屏幕为点亮状态。
显示设备的待机模式和运行模式可以相互切换。对于处于运行模式的显示设备，当用户操作控制装置上的电源键或者通过语音控制进行关机时，处于运行模式的显示设备进入待机模式。对于处于待机模式的显示设备，当用户操作控制装置上的电源键或通过语音控制进行开机时，处于待机模式的显示设备进入运行模式。
然而，基于图4中显示设备的配置框图，具有语音唤醒功能的显示设备，在待机模式下，用于采集用户声音数据的麦克风模块和用于处理包含唤醒词的用户声音数据的MCU模块需要一直保持上电才能工作，这使得待机模式下的显示设备的待机功耗较大。
图5中示例性示出了显示设备的又一种配置框图。如图5所示，显示设备200”可以包括电源板21、主板23、麦克风模块25、环境音检测模块27。这些组件在一定程度上可以对应于图3中部分组件。
与图4不同的是，图5中增加了环境音检测模块27。
环境音检测模块27，用于检测环境音的大小，并根据环境音的大小控制麦克风模块25和MCU模块23b的开启或关闭。环境音检测模块27可以对应于图3中的检测器230。
这里，图5中麦克风模块25和环境音检测模块27集成在一起与主板23连接，但也可以分开单独与主板23连接，具体不作限定。
图5所示的显示设备，尤其是该显示设备具有语音唤醒功能时，可以控制其待机模式下的待机功耗。各模块的具体功能将在下面做详细描述。
SOC模块23a，用于将显示设备进入待机模式或运行模式的状态通知MCU模块23b，以使MCU模块23b控制环境音检测模块27开启或关闭。
MCU模块23b，用于控制环境音检测模块27的开启或关闭，同时用于识别用户输入的语音数据，并在识别出用户输入的语音数据为语音唤醒指令时，触发SOC模块23a控制显示设备由待机模式进入运行模式。
麦克风模块25，用于采集用户输入的语音数据，并将该语音数据传输至MCU模块23b。例如包含唤醒词的语音数据。
环境音检测模块27，用于检测环境音的大小，并根据环境音的大小控制麦克风模块25和MCU模块23b的开启或关闭，从而能够控制具有语音唤醒功能的显示设备处于待机模式下的待机功耗。
在实施例一中，如图5所示，在显示设备处于待机模式下，环境音检测模块27保持上电，即处于开启状态，麦克风模块25和MCU模块23b可以根据是否满足环境音检测模块27的设定条件而交替性的保持上电(即处于开启状态)或掉电(即处于关闭状态)，以及SOC模块23a保持掉电，即处于关闭状态。
具体的，具有语音唤醒功能的显示设备，SOC模块将显示设备进入待机模式的状态通知MCU模块后：
MCU模块通过上电方式控制环境音检测模块开启。
环境音检测模块开启后，首先通过断电方式控制MCU模块及麦克风模块关闭。其次可以采集外界的环境音；检测环境音的大小；并判断环境音大小是否在预设范围内，以通过上电或断电方式控制麦克风模块和MCU模块的开启或关闭。
可选的，环境音检测模块判断环境音大小未在预设范围内时，表示当前处于用户可能无需观看显示设备的环境音场景，即该场景下用户将待机模式的显示设备唤醒的概率几乎为0，从而该场景下无需麦克风模块和MCU模块持续工作，所以环境音检测模块通过断电方式保持麦克风模块和MCU模块关闭，这样可以大大降低由于麦克风模块和MCU模块一直上电而带来的待机功耗。
可选的，环境音检测模块判断环境音大小在预设范围内时，表示当前处于用户可能需要观看显示设备的环境音场景，即该场景下用户有较大概率需要将待机模式的显示设备唤醒，从而该场景下需要麦克风模块和MCU模块持续检测工作，所以环境音检测模块通过上电方式控制麦克风模块和MCU模块开启，以检测用户是否发出语音唤醒指令而唤醒显示设备进入运行模式。
这里，预设范围可以根据经验或试验设定，示例性的，预设范围为40～70分贝，例如45分贝、55分贝、65分贝等。该范围内环境较适宜，如家人一起吃晚饭时或晚饭之后的状态，此环境场景下用户有较大概率需要将待机模式的显示设备唤醒；40分贝以下时环境较安静，如夜晚睡觉或白天无人状态，此环境场景下用户可能不会将待机模式的显示设备唤醒；70分贝以上时环境较吵闹，如白天邀请朋友聚会状态，此环境下用户将待机模式的显示设备唤醒的概率很小。
此外，需要注意的是，环境音检测模块上电引起的功耗远小于麦克风模块和MCU模块上电引起的功耗。
在该实施例中，根据环境音检测模块检测的环境音大小是否在预设范围内，来间歇性的控制麦克风模块和MCU模块二者同时开启或关闭，从而能够控制处于待机模式下的显示设备的部分待机功耗。
在实施例二中，如图5所示，在显示设备处于待机模式下，环境音检测模块27可以根据是否满足预定义条件而周期性保持上电(即处于开启状态)或掉电(即处于关闭状态)，麦克风模块25和MCU模块23b可以根据是否满足环境音检测模块27的设定条件而交替性的保持上电(即处于开启状态)或掉电(即处于关闭状态)，以及SOC模块23a保持掉电(即处于关闭状态)。
与实施例一不同的是，SOC模块将显示设备进入待机模式的状态通知MCU模块后：
MCU模块通过上电方式控制环境音检测模块开启。
环境音检测模块开启后，首先通过断电方式控制MCU模块及麦克风模块关闭。其次环境音检测模块启动计时，并根据计时时长是否超过设定时长，来控制自身的开启或关闭。
可选的，环境音检测模块计时时长超过设定时长时，通过断电方式控制自身关闭，并保持麦克风模块和MCU模块关闭。这样可以大大降低由于麦克风模块和MCU模块一直上电而带来的待机功耗。
可选的，环境音检测模块计时时长未超过设定时长时，保持自身开启；同时可以采集外界的环境音；检测环境音的大小；并判断环境音大小是否在预设范围内，以通过上电或断电方式控制麦克风模块和MCU模块的开启或关闭。这样，能够进一步降低由于麦克风模块和MCU模块一直上电而带来的待机功耗。
这里，环境音检测模块根据环境音大小是否在预设范围内，来控制麦克风模块和MCU模块的开启或关闭，具体实现方式可以参照上述实施例一。
这里，设定时长可以是环境音检测模块开启一次的持续时长，例如设定时长可以是60分钟。且设定时长可以根据经验和实验设定。
在该实施例中，根据环境音检测模块开启的时长是否超过设定时长，来周期性的控制环境音检测模块的开启或关闭，进一步周期性控制麦克风模块和MCU模块二者同时开启或关闭，从而也能够控制处于待机模式下的显示设备的部分待机功耗。
在实施例三中，如图5所示，在显示设备处于待机模式下，麦克风模块25和MCU模块23b，以及环境音检测模块27，三者之间可以根据是否满足预先设定的条件而交替性的保持上电(即处于开启状态)或掉电(即处于关闭状态)，而SOC模块23a保持掉电(即处于关闭状态)。
与实施例一和实施例二不同之处包括以下两个方面。
一方面，在环境音检测模块判断环境音大小在预设范围内时，通过上电方式控制麦克风模块和MCU模块开启之后，为了进一步降低由于麦克风模块和MCU模块保持上电而又长时间未检测到用户发出的语音唤醒指令导致的待机功耗，在上述实施例基础上，开启MCU模块和麦克风模块的同时，令MCU模块启动计时。
若计时时长超过设定时长，表示当前处于用户可能无需观看显示设备的环境音场景，即该场景下用户将待机模式的显示设备唤醒的概率很小，也就是说用户没有进一步操作，例如没有发出语音，从而该场景下无需麦克风模块和MCU模块持续工作，所 以MCU模块通过上电方式控制环境音检测模块开启，同时环境音检测模块开启后通过断电方式控制MCU模块及麦克风模块关闭。从而可以进一步降低由于麦克风模块和MCU模块长时间上电而未检测到用户语音所带来的待机功耗。
若计时时长未超过设定时长，表示当前处于用户可能需要观看显示设备的环境音场景，即该场景下用户有较大概率需要将待机模式的显示设备唤醒，从而该场景下需要麦克风模块和MCU模块持续检测工作，所以保持开启麦克风模块和MCU模块，以及保持关闭环境音检测模块，使得麦克风模块持续准备采集用户输入的语音，MCU模块持续识别用户输入的语音，并在识别出用户输入的语音为语音唤醒指令时触发SOC模块控制显示设备由待机模式进入运行模式。
这里，设定时长可以是判断一次环境音大小在预设范围内时保持打开麦克风模块和MCU模块的持续时长，例如设定时长可以是15分钟。且设定时长可以根据经验和实验设定。
另一方面，在环境音检测模块判断环境音大小在预设范围内时，环境音检测模块通过上电方式控制麦克风模块和MCU模块开启，以检测用户是否发出语音唤醒指令而唤醒显示设备进入运行模式。同时，MCU模块开启后通过断电方式控制环境音检测模块关闭，这样降低由于环境音检测模块的持续上电而进一步带来的待机功耗。
在该实施例中，在环境音检测模块检测出环境音的大小在预设范围内时，进一步通过判断麦克风模块和MCU模块的开启时长是否超过设定时长，来进一步控制麦克风模块和MCU模块同时开启或关闭，从而也能够控制处于待机模式下的显示设备的部分待机功耗。
在上述实施例一、实施例二和实施例三的基础上，在显示设备处于运行模式下，麦克风模块25、MCU模块23b和SOC模块23a均保持上电(即处于开启状态)，而环境音检测模块27保持掉电(即处于关闭状态)。
具体的，当处于待机模式的显示设备通过语音唤醒功能被唤醒而进入运行模式时，SOC模块将显示设备进入运行模式的状态通知MCU模块后：
MCU模块通过断电方式控制环境音检测模块关闭，从而使得麦克风模块持续准备采集用户输入的语音，MCU模块持续接收用户输入的语音，并将该语音传输至SOC模块，以供SOC模块识别出该语音对应的语音控制指令、并执行与语音控制指令对应的功能。
在一个示例中，MCU模块、麦克风模块和环境音检测模块之间，可以通过高低 电平的触发来实现上电或断电，进而实现开启或关闭。
图6中示例性示出了图5中各模块的电路配置框图。如图6所示，VCC check为环境音检测模块的电源，显示设备待机模式/开机模式时一直为高电平；VCC MIC为麦克风模块的电源，显示设备待机模式/开机模式时一直为高电平；VCC MCU为MCU模块的电源，显示设备待机模式/开机模式时一直为高电平。
在一个示例中，显示设备进入待机模式时，MCU模块可以控制CTRCL 2输出端输出高电平，其可以控制三极管Q1导通，从而逻辑模块的CTRL 4输入端输入为低电平，经逻辑模块处理，从逻辑模块的CTRL3输出端输出高电平；CTRL 3输出端输出高电平时，其可以控制三极管Q2导通，从而控制第一开关模块导通，所以最终控制环境音检测模块上电。环境音检测模块可以控制CTRL 1输出端输出高电平，其可以控制三极管Q3导通，从而分别控制三极管Q4和Q5截止，进一步控制第二开关模块和第三开关模块断开，所以最终控制MCU模块和麦克风模块断电。即待机模式时：环境音检测模块上电而开启，MCU模块和麦克风模块断电而关闭。
在一个示例中，当待机模式下环境音检测模块检测到环境音大小在预设范围内时，环境音检测模块可以控制CTRL1输出端输出低电平，其可以控制三极管Q3截止，从而分别控制三极管Q4和Q5导通，进一步控制第二开关模块和第三开关模块导通，所以最终控制MCU模块和麦克风模块上电。MCU模块可以控制CTRCL2输出端输出低电平，其可以控制三极管Q1截止，从而逻辑模块的CTRL 4输入端输入为高电平，经逻辑模块处理，从逻辑模块的CTRL3输出端输出低电平；CTRL3输出端输出低电平时，其可以控制三极管Q2截止，从而第一开关模块断开，所以最终控制环境音检测模块断电。即待机模式下环境音检测模块检测到环境音大小在预设范围内时：MCU模块和麦克风模块上电而开启，环境音检测模块断电而关闭。
在一个示例中，当待机模式下MCU模块计时时长超过设定时长时，MCU模块可以控制CTRCL2输出端输出高电平，进一步控制CTRL3输出端输出高电平，最终控制环境音检测模块上电。环境音检测模块可以控制CTRL1输出端输出高电平，最终控制MCU模块和麦克风模块断电。即待机模式下MCU模块计时时长超过预设时长时：环境音检测模块上电而开启，MCU模块和麦克风模块断电而关闭。
在一个示例中，显示设备进入运行模式时，环境音检测模块可以控制CTRL1输出端输出低电平，最终控制MCU模块和麦克风模块上电。MCU模块可以控制CTRCL2输出端输出低电平，进一步控制CTRL3输出端输出低电平，最终控制环境音检测模块 断电。即运行模式时：MCU模块和麦克风模块上电而开启，环境音检测模块断电而关闭。
图6中，第一开关模块、第二开关模块和第三开关模块可被实施为包括MOS管和负载电阻，逻辑模块可被实施为具有二选一功能的数据选择器的形式。另外，图6仅是示例性的示出了显示设备中各模块的电路配置形式，作为本申请中的优选实施例的电路配置形式，实际应用中不作具体限定。
在上述示出的实施例中，通过在显示设备中引入“环境音检测模块”，并且，通过对处于待机模式下的显示设备中各个模块的开启或关闭进行间歇性的控制，从而能够控制显示设备的待机功耗。特别是对处于待机模式下的显示设备，间歇性的控制麦克风模块和MCU模块二者同时开启或关闭，与一直保持麦克风模块和MCU模块的开启相比，可以大大降低处于待机模式下的显示设备的待机功耗。
出于说明和描述的目的，提供了前述实施例，而非旨在穷举或限制本公开。具体实施例的各个元件或特征通常不限于该具体实施例，而是在适用情况下即使未具体示出或描述也可在所选实施例中使用或互换。同样也可以许多形式变型，这种变型不被认为是脱离本公开，而且所有这样的修改被涵盖在本公开的范围内。
