具体实施方式
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，本领域普通技术人员在没有做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。
<控制方法>
在本申请的一个实施例中，提供一种音频控制方法，所述音频控制方法用于控制可穿戴设备，在该方法中，执行主体为处理器。图1为本申请实施例的可穿戴设备的音频控制方法流程图。
如图1所示，该控制方法包括：
S101、提供声波导结构，所述声波导结构被配置为能够实现声音聚焦的功能；
S102、获取声波导结构的运行状态，在所述运行状态为所述声波导结构处于开启状态的情况下，生成第一控制信号；
S103、根据所述第一控制信号减小所述可穿戴设备的扬声器的声音大小。
例如，可穿戴设备为具有音频功能的智能眼镜等。其中，声波导结构为能够实现声聚焦的功能的结构。如图1所示，可穿戴设备的处理器获取声波导结构的运行状态，当处理器获取的声波导结构的运行状态为开启时，生成第一控制信号，以减小扬声器的声音大小。当处理器获取的声波导结构的运行状态为关闭时，不改变扬声器的声音的大小。
例如，当用户佩戴智能眼镜时，处理器获取声波导结构处于开启的状态，处理器生成第一控制信号。处理器根据第一控制信号，将扬声器的声音减小至设定大小。
例如，在开启声波导结构之前的声音响度为40dB,在处理器检测到声波导结构被开启后，将扬声器声音的响度被降低至30dB。这样，声波导结构本身具有声音的聚焦功能，从而阻止了声音的外泄，同时，扬声器的音量被降低，能够起到更好的防止声音外泄的效果。此外，避免了声波导结构被开启，声音被聚焦后，用户接收到声音的响度更高，从而对用户的听觉造成影响。
通过这样的方式，在声波导结构处于开启的状态下，在声波导结构的阻挡下，由出声孔向四周传播的声音能够朝向用户的方向聚拢。这样，在声音输出频率相同的情况下，用户听到的声音的响度会更大。因此，即使处理器减小了可穿戴设备扬声器的响度，也不会造成用户听觉障碍。这样，在增加可穿戴设备的私密性的同时，保证用户的使用体验。
在本申请的一个实施例中，上述控制方法在获取声波导结构的运行状态之前，还包括：
S200、获取环境噪音，在所述环境噪音大于或等于设定阈值的情况下，生成第一提示信号，所述第一提示信号用于提示用户是否开启所述声波导结构。
如图2所示，处理器获取环境噪音，在获取的环境噪音大于或等于设定阈值的情况下，处理器判定当前为高噪声环境。高噪环境是指，当环境噪音大于或等于设定阈值时所处的噪音环境。在获取的环境噪音大于或等于设定阈值的情况下，处理器发出第一提示信号。当处理器收到第一提示信号的反馈为“是”的情况时，进行步骤S201，处理器获取声波导结构的运行状态，当处理器获取的声波导结构的运行状态为开启时,生成第一控制信号。而后进行步骤S202，扬声器的声音被减小。当处理器收到第一提示信号的反馈为“否”的情况时，结束该音频控制。
例如，在处理器获取声波导结构的运行状态之前，处理器获取环境噪音，当环境噪音落入设定阈值或阈值范围，或与设定阈值相同时，处理器向用户发出第一提示信号。第一提示信号可以为语音信号或振动信号，以能对用户形成提示为准。处理器获取“是”的反馈后，处理器获取声波导结构的运行状态，处理器获取到声波导结构处于开启的状态时，处理器 将扬声器的声音减小。
处理器能够识别环境噪音，从而判定当前用户所处的噪音环境，当环境噪音符合设定的阈值时，处理器判断高噪环境。并主动提示用户以使用户选择是否开启声波导结构。通过在高噪环境下，主动提示用户开启声波导结构，以实现声音的聚焦功能，并同时降低在高噪环境下扬声器音量的大小。从而，能够保证用户在高噪环境下，能够清楚的接收来自扬声器的声音，同时，还能够防止用户隐私被泄露。
在本申请的一个实施例中，在生成所述第一提示信号后间隔设定时间，再获取所述声波导的运行状态。
如图3所示，处理器被设定为在生成第一提示信号后的设定间隔时间后，处理器再获取声波导的运行状态。例如，在生成第一提示信号后的2秒后，处理器开始获取声波导的运行状态。
在本申请的一个实施例中，所述获取环境噪音包括：
获取环境声音；
获取语音；
计算所述环境声音与所述语音的差值，所述环境噪音为所述差值。
例如，处理器获取环境声音以及语音，处理器计算环境声音的响度与语音的响度之间的差值，得出环境噪音。将该环境噪音与设定好的阈值进行比对。
这样，能够准确地获取环境噪音，从而判定高噪音环境。
在一个例子中，该设定的阈值为85dB。
例如，当环境声音的响度为100dB，语音的响度为10dB。环境噪音为90dB。环境噪音大于设定的阈值85dB，处理器判定当前为高噪环境。如图2及图3所示，当环境噪音大于或等于85dB时，当前所处环境为高噪环境。在被识别为高噪环境后，处理器获取声波导结构被开启，处理器将扬声器的声音减小至设定大小。或是，也可以在被识别为高噪环境后，处理器生成第一提示信号，当收到用户的“是”的反馈后，处理器获取声波导结构的运行状态，处理器获取声波导结构被开启，处理器将扬声器的声音减小至设定大小。
这样，在声波导结构的基础上，结合环境噪音的判定功能，从而使得能够根据噪音环境，对用户进行提示，以提醒用户开启声波导结构，并根据声波导是否被开启的状态，对音频的响度进行自动调节，以避免声波导结构在开启后，声音变大，对用户的听觉感受造成影响。
在本申请的一个例子中，所述可穿戴设备包括麦克风和骨传导音频感测装置，所述麦克风用于获取环境声音，所述骨传导音频感测装置用于获取语音；
在所述获取环境噪音之前还包括：
获取所述可穿戴设备的运行模式，在所述运行模式为音乐模式的情况下，生成第二提示信号；
所述第二提示信号用于提示用户是否开启所述麦克风和所述骨传导音频感测装置。
如图4所示，处理器获取可穿戴设备的运行模式。可穿戴设备具有通话模式和音乐模式。音乐模式中包括音乐播放模式和视频播放模式。当处理器获取运行模式为音乐模式时，生成第二提示信号，并向外发送，以提示用户开启麦克风和骨传导音频感测装置，从而获取环境噪音。
例如，在处理器获取智能眼镜处于音乐模式的情况下，处理器发出第二提示信号。在处理器收到第二提示信号的反馈为“是”的情况下，进行步骤401，获取环境噪音，当环境噪音大于或等于设定阈值时，处理器生成第一提示信号。在处理器生成第一提示信号后，进行步骤402，在生成第一提示信号后的设定时间获取声波导结构的运行状态。当声波导结构处于开启的状态时，生成第一控制信号，并根据第一控制信号，降低扬声器声音的大小。
通过这样的方式，能够对用户的使用状态进行判定，从而根据用户的需要提示是否开启声波导结构。
在一个实施例中，如图5所示，在获取声波导结构的运行状态前还包括：获取所述可穿戴设备的运行模式，在所述运行模式为通话模式的情况下，获取所述声波导结构的运行状态，在所述运行状态为所述声波导结构处于开启状态的情况下，生成第二控制信号，所述第二控制信号用于将 所述扬声器的频率调整至设定范围。
例如，如图5所示，处理器获取可穿戴设备的运行模式。当可穿戴设备处于通话模式时，处理器获取声波导结构是否处于开启的状态，当声波导结构处于开启的状态下时，处理器生成第二控制信号，并向外发送，以将扬声器的频率调整至设定的范围。
例如，当使用智能眼镜接听或拨打电话时，当处理器识别智能眼镜处于通话模式下，处理器获取声波导结构的运行状态，在声波导结构处于开启的状态的情况下，处理器减小扬声器的声音大小。同时，处理器生成第二控制信号，将扬声器的频率调整至设定的范围。
在这里，不对生成第一控制信号和第二控制信号的先后顺序进行限定，与不对处理器调整扬声器的频率和扬声器声音大小的先后顺序进行限定，本领域技术人员可以根据需要自行选择。
这样，在用户处于通话模式时，在对声波导结构从而能够进一步地保护用户通话的私密性。
例如，所述设定范围为300Hz-4KHz。
例如，在正常的情况下，扬声器的频率为低于8kHz的频段。当处理器获取声波导结构处于开启的状态下，将低于8kHz的频段集中至300Hz-4KHz。
这样，能够使得通话音频更加清晰。
在一个例子中，在将扬声器的频率调整至300Hz-4KHz的同时，调低音量至设定的强度。
这样，能够进一步地增加用户的私密性，防止扬声器漏音的情况发生。
如图8所示，图8为本申请实施例中可穿戴设备的音频控制方法的响应频率效果图。图8中的横坐标为骨传导音频感测装置感测的语音信号的频率，纵坐标为在该语音信号频率下，用户能够感受到的声音的响度。L2为声波导结构开启后，响应频率的曲线。L1为声波导结构关闭后，响应频率的曲线。在相同的语音信号的频率下，在声波导结构开启时用户感受到的声音的响度明显高于在声波导结构关闭时用户感受到的声音的响 度。
因此，通过本申请中的音频控制方法，用户感受到的声音的响度更高，因此，在降低扬声器声音的响度时，也不会影响用户感受到的声音的响度。这样，在保证用户能够接收良好的语音信号的前提下，能够保证用户的私密性。
<可穿戴设备>
在本申请的一个实施例中，提供一种可穿戴设备，可穿戴设备包括声波导结构，所述声波导结构被配置为能够实现声音聚焦的功能；
检测模块，所述检测装置被配置为用于检测所述声波导结构的运行状态，并向外发送；
音频调节模块，所述音频调节装置被配置为用于调节所述扬声器的声音大小；
处理器，所述处理器被配置为用于获取所述声波导结构的运行状态，在所述声波导结构处于开启的状态下，所述处理器生成第一控制信号，并向外发送；
所述音频调节模块获取所述第一控制信号，并减小所述可穿戴设备的扬声器的声音大小。
如图7所示，智能眼镜具有外壳，在外壳上设置有出声孔，在外壳中，与出声孔相对的位置设置有音频组件，音频组件具有扬声器。扬声器发出的声音能够通过出声孔向外传播并被用户接收。声波导结构位于外壳上，并位于出声孔远离用户的一侧。
例如，声波导结构为可以移动的挡板403，挡板403可以为直板或挡板403可以具有弧度。在声波导结构被开启的情况下，挡板403由壳体内伸出，以防止出声孔的声波向外扩散，改变出声孔的声波的传播方向；在声波导结构被关闭的情况下，挡板403伸入壳体并收纳于壳体中。
例如，检测模块为霍尔传感器，在声波导结构的挡板403上设置有与霍尔传感器相配合的磁性元件。霍尔传感器处在运行的状态，当带有磁性元件的挡板403伸出壳体时，磁性元件靠近霍尔传感器，并与霍尔传感器形成感应。根据霍尔传感器是否与磁性元件形成感应的状态判断，从而 判断声波导结构的运行状态。处理器检测出声波导结构被开启后，处理器生成第一控制信号。音频调节模块能够获取第一控制信号，音频调节模块将扬声器的音量调低。音频调节模块为能够调节扬声器声音大小的模块，本领域技术人员可以自行选择。
通过这样的方式，在声波导结构处于开启的状态下，声波导结构能够在出声孔与外界之间形成物理阻隔，从而起到了避免声音外泄的效果。同时，在声波导结构的阻挡下，由出声孔向四周传播的声音能够朝向用户的方向聚拢。这样，在声音输出频率相同的情况下，用户听到的声音的响度会更大。这样，在增加可穿戴设备的私密性的同时，保证用户的使用体验。
在本申请的一个实施例中，可穿戴设备还包括提示模块。该提示模块用于接收第一提示信号，并做出相应的提示，以提醒用户选择是否开启声波导结构。当用户选择开启后，处理器获取“是”的反馈后，处理器获取声波导结构被开启，处理器将扬声器的声音减小至设定大小。
在一个例子中，所述可穿戴设备包括麦克风和骨传导音频感测装置，所述麦克风用于获取环境声音，所述骨传导音频感测装置用于获取语音。
麦克风用于收集环境声音。骨传导音频感测装置用户获取下行的语音信号，下行语音信号为骨传导音频感测装置接收到的语音信号，该语音信号与环境声音不同。
在一个例子中，提示模块还能够接收第二提示信号。当处理器识别可穿戴设备处于音乐模式时，处理器生成第二提示信号。处理器获取麦克风和骨传导音频感测装置的工作模式判定可穿戴设备的工作模式。当麦克风处于开启状态，且骨传导音频感测装置也处于开启状态时。可穿戴设备为通话模式；当麦克风处于关闭状态，骨传导音频感测装置处于开启状态时，可穿戴设备为音乐模式。第二提示信号用于提示用户是否开启麦克风和骨传导音频感测装置，以获取环境噪音。
