一种移动终端及其实现通话中切换麦克风的方法
【技术领域】
本发明涉及移动终端技术领域，特别是涉及一种移动终端及其实现通话中切换麦克风的方法。
【背景技术】
在传统的双面液晶显示中，由于采用透射式液晶面板，需应用到两片液晶显示屏以及相应的背光源，所以厚度较厚且功耗很高，尤其是在明亮的户外进行显示时，显示屏需要较高的亮度才能看清楚，因此就需要显示器背光具有很高的亮度，这样会导致显示器功耗很高，不利于节能减排。如图1所示，图1是现有技术中一种常用的双面液晶显示器结构示意简图。
随着智能终端的发展与普及，手机、平板电脑等移动终端已经成为人们生活中不可或缺的一部分，给用户的日常生活提供了极大的便利。
通常移动终端在其上、下两端分别设置听筒和麦克风，其中麦克风用于接收用户的声音信息，听筒用于播放来电者的声音信息进而实现通讯功能。但是，移动终端普遍采用雷同或相似的设计，显示屏幕占据了移动终端正面的大部分面积，且移动终端的上、下两端设计比较对称，不容易分辨移动终端的方向，使得在接听电话时，需要用户先辨识移动终端是否拿错了方向，否则容易将下端的麦克风远离用户的声源位置，进而可能造成接收到用户的声音信息的失真。这是因为如果用户的声音距离下端的麦克风较远，则麦克风采集到的声音信息或将该声音信息传输到来电者的通讯设备时由来电者接听到的声音信息将受到很大程度的影响，从而与用户实际的声音信息有很大差异，可能造成通讯过程中的沟通障碍。
因此，现有需要辨识移动终端的方向再进行通讯的技术不能满足人们便捷的进行清晰、准确通话的要求。

【具体实施方式】
为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。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。
请参阅图1，图1是图1是本发明提供的移动终端一实施方式的示意框图。如图1所示，该移动终端10包括声源判断模块110、切换模块120、至少两个麦克风，图1中示例为两个麦克风如第一麦克风131和第二麦克风132，以及至少两个听筒，图1中示例为两个听筒如第一听筒161和第二听筒162，其中声源判断模块120用于在移动终端10接通来电时判断用户的声源位置，切换模块120用于根据声源位置对至少两个麦克风如第一麦克风131和第二麦克风132进行切换，以控制至少两个麦克风如第一麦克风131和第二麦克风132中的部分麦克风作为主麦克风来接收声源位置发出的第一声音信号。进一步，声源判断模块110还可以用于判断用户的接听位置，切换模块120用于根据接听位置对至少两个听筒如第一听筒161和第二听筒162进行切换，以控制至少两个听筒如第一听筒161和第二听筒162中的部分听筒作为主听筒来播放接听到的第二声音信号。如本领域技术人员所理解的，在本发明中麦克风和听筒的数量不限于两个，而可以是两个以上的任意数量。如本领域技术人员所理解的，本发明的移动终端可以仅设置至少两个麦克风或至少两个听筒，此时声源判断模块110仅对麦克风或听筒进行切换。
其中，移动终端10选自但不限于方便携带的手机、平板电脑或掌上电脑等。
请参阅图2，图2是用于显示图1中的麦克风和听筒在移动终端上的相对位置关系的结构示意图。如图2所示，该移动终端10还包括显示屏140（例如，电容显示屏）和前置摄像头150。如图2所示，第一麦克风131、前置摄像头150、第一听筒161位于移动终端10或电容显示屏140的上端，第二麦克风132、第二听筒162位于移动终端10或电容显示屏140的下端。
具体的，如图1和图2所示的移动终端10，在接通来电时，声音判断模块110判断用户的声源位置，可选是通过判断第一麦克风131和第二麦克风132接收到的用户的第一声音信号或其他声音信号的音量大小来判断用户的声源位置，如若第一麦克风131接收到的音量大于第二麦克风132接收到的音量，判断为用户的声源位置靠近第一麦克风131，否则判断为靠近第二麦克风132；切换模块120根据声源位置对第一麦克风131和第二麦克风132进行切换，以控制其中的一个作为主麦克风来接收声源位置发出的第一声音信号，如若判断为用户的声源位置靠近第一麦克风131，则控制第一麦克风131作为主麦克风来接收声源位置发出的第一声音信号，进一步可选关闭第二麦克风132或第二麦克风132用于接收环境噪声，使得第一声音信号能够更清晰的传输到来电者的通信设备。同理，若判断为用户的声源位置靠近第二麦克风131，则控制第二麦克风132作为主麦克风来接收声源位置发出的第一声音信号，进一步可选关闭第二麦克风132或将第二麦克风132用于接收环境噪声。
其中，在其他实施方式中，声音判断模块110判断用户的声源位置可选采用不限于上述的方式，如可选是通过判断第一麦克风131附近第一位置处的第一声音传感器和第二麦克风132附近第二位置处的第二声音传感器接收到的第一声音信号或其他声音信号的音量大小来判断用户的声源位置，与上述判断用户的声源位置的方式相似，此处不再赘述；进一步还可选声源判断模块110通过移动终端10的加速度传感器判断该移动终端10的方向状态，进而解析得到用户的声源位置，如若判断移动终端10为如图2所示的正向状态，则解析得到用户的声源位置接近下端的第二麦克风132，进而切换模块120控制该第二麦克风132作为主麦克风；若判断移动终端10为反向状态，则解析得到用户的声音位置接近上端的第一麦克风131，进而切换模块120控制该第一麦克风131作为主麦克风。
进一步的，当声源判断模块110判断为用户的声源位置靠近第一麦克风131时，则可以推断出用户的接听位置靠近第二听筒162，而用户的声源位置靠近第二麦克风132时，则可以推断出用户的接听位置靠近第一听筒161，进而选择更靠近接听位置的第一听筒161或第二听筒162来播放接听到的第二声音信号。
请参阅图3，图3是本发明提供的移动终端另一实施方式的示意框图。如图3所示，该移动终端30包括声源判断模块310、切换模块320、至少两个麦克风，其中图3中示例为四个麦克风如第一麦克风331、第二麦克风332、第三麦克风333和第四麦克风334以及至少两个听筒，其中图3中示例为四个听筒如第一听筒361、第二听筒362、第三听筒363和第四听筒364，其中声音判断模块310和切换模块320与上述实施方式中声源判断模块110和切换模块120的结构和作用相同，此处不再赘述，该移动终端30进一步包括图像获取模块340，图像获取模块340用于在移动终端30接通来电时，获取用户的耳廓图像，声源判断模块310进一步用于根据耳廓图像判断用户的声源位置或接听位置。
其中，声源判断模块310根据耳廓图像确定移动终端30相对于用户的设置方向，并根据设置方向确定声源位置或接听位置，切换模块320将距离声源位置最近的部分麦克风作为主麦克风，并可进一步将距离接听位置最近的部分听筒作为主听筒。如本领域技术人员所理解的，本发明的移动终端可以仅设置至少两个麦克风或至少两个听筒，此时声源判断模块310仅对麦克风或听筒进行切换。
请参阅图4，图4是用于显示图3中麦克风和听筒在移动终端上的相对位置关系的结构示意图。如图4所示，该移动终端30还包括显示屏340（例如，电容显示屏）和前置摄像头350，图4中示例第一麦克风331、第一听筒361和前置摄像头350位于移动终端30或电容显示屏340的上端，第二麦克风332和第二听筒362位于移动终端30或电容显示屏340的下端，第三麦克风333和第三听筒363位于移动终端30或电容显示屏340的左侧，第四麦克风334和第四听筒364位于移动终端30或电容显示屏340的右侧。
其中，声源判断模块310根据耳廓图像确定移动终端30相对于用户的设置方向，并根据设置方向确定声源位置或接听位置。具体的，声源判断模块310根据耳廓图像341判断出耳轮与耳垂的轮廓曲线，并根据二者的连线相对于移动终端30的位置关系来判断确定移动终端30相对于用户的设置方向。例如，根据耳轮到耳垂的连线（如耳轮最高点到耳垂最低点的连线）与移动终端30的边缘的交点判断声源位置，根据耳轮到耳垂的连线（如耳轮最高点到耳垂最低点的连线）的反向延长线与移动终端30的边缘的交点判断接听位置。
如图4所示，若图像获取模块340获取到第一耳廓图像341，其包括耳轮3411和耳垂3412等特征，声源判断模块310根据第一耳廓图像341具体是以耳轮3411最高点指向耳垂3412最低点的连线3413与移动终端30的边缘具体是下边缘具有交点301，确定移动终端30相对于用户是正向的设置方向，即认为是正常正向手持该移动终端30，并根据该移动终端正向的设置方向确定声源位置，可选将交点301或其附近的位置确定为声源位置，切换模块320将距离该声源位置如交点301最近的第二麦克风332作为主麦克风。
可以理解的是，如图4所示，若图像获取模块340获取到第二耳廓图像342，声源判断模块310根据第二耳廓图像342具体是以其耳轮最高点指向耳垂最低点的连线3423与移动终端30的边缘具体是上边缘具有交点302确定移动终端30相对于用户是反向的设置方向，即认为是反向手持该移动终端30，并根据该移动终端30反向的设置方向确定声源位置，可选将交点302或其附近的位置确定为声源位置，切换模块320将距离该声源位置如交点302最近的第一麦克风331作为主麦克风。若图像获取模块340获取到第三耳廓图像343，声源判断模块310根据第三耳廓图像343具体是以耳轮最高点指向耳垂最低点的连线3433与移动终端30的边缘具体是右边缘具有交点303，确定移动终端30相对于用户是横向向后的设置方向，即认为是横向向后手持该移动终端30，并根据该移动终端横向向后的设置方向确定声源位置，可选将交点303或其附近位置确定为声源位置，切换模块320将距离该声源位置如交点303最近的第四麦克风334作为主麦克风。同理可知，若图像获取模块340获取到第四耳廓图像344，声源判断模块310根据第四耳廓图像344具体是以耳轮最高点指向耳垂最低点的连线3443与移动终端30的边缘具体是左边缘具有交点304，确定移动终端30相对于用户是横向向前的设置方向，即认为是横向向前手持该移动终端30，并根据该移动终端横向向前的设置方向确定声源位置，可选将交点304或其附近位置确定为声源位置，切换模块320将距离该声源位置如交点303最近的第四麦克风334作为主麦克风。
其中，切换模块310在控制至少两个麦克风中一个作为主麦克风后，进一步可选关闭其他麦克风或将其他麦克风用于接收环境噪声，使得第一声音信号能够更清晰的传输到来电者的通信设备。
其中，如图4所示，耳廓图像341、342、343或344可以是利用摄像头如前置摄像头350对耳廓进行拍摄后获得的彩色或单色图像，也可以是利用电容显示屏340对耳廓进行电容检测后获得电容分布图，即图像获取模块340进一步用于利用移动终端30的电容显示屏340或摄像头350获取用户的耳廓图像。
进一步的，声源判断模块310进一步根据耳廓图像判断用户的接听位置，切换模块320用于根据接听位置对至少两个听筒如第一听筒361、第二听筒362、第三听筒363和第四听筒364进行切换，以控制至少两个听筒如第一听筒361、第二听筒362、第三听筒363和第四听筒364中部分听筒作为主听筒来播放接听到来自来电者的第二声音信号。请继续参阅图4，声源判断模块310进一步根据耳廓图像判断用户的接听位置，如根据第一耳廓图像341具体是根据上述耳轮3411最高点指向耳垂3412最低点的连线3413的反向延长线与移动终端30边缘具体是上边缘具有交点301'，将交点301'或其附近的位置确定为接听位置，切换模块320进一步用于将距离该接听位置如交点301'最近的第一听筒361设置为主听筒。同理，对于第二耳廓图像342，声源判断模块310进一步将连线3423的反向延长线与移动终端30边缘具体是下边缘具有交点302'，将交点302'或其附近的位置确定为接听位置，切换模块320进一步用于将距离该接听位置如交点302'最近的第二听筒362设置为主听筒；对于第三耳廓图像343，声源判断模块310进一步将连线3433的反向延长线与移动终端30边缘具体是左边缘具有交点303'，将交点303'或其附近的位置确定为接听位置，切换模块320进一步用于将距离该接听位置如交点303'最近的第三听筒363设置为主听筒；对于第四耳廓图像344，声源判断模块310进一步将连线3443的反向延长线与移动终端30边缘具体是右边缘具有交点304'，将交点304'或其附加的位置确定为接听位置，切换模块320进一步用于将距离该接听位置如交点304'最近的第四听筒364设置为主听筒。
在其他实施方式中，声源判断模块310可选根据人体耳朵与嘴巴的器官位置关系，将上述确定得到的声源位置作为嘴巴位置计算获得人体耳朵位置作为接听位置，以由切换模块将距离耳朵位置最近的听筒作为主听筒。

区别于现有技术的情况，本发明提供的移动终端接包括声源判断模块、切换模块以及至少两个麦克风，其中声源判断模块用于在移动终端接通来电时判断用户的声源位置，切换模块用于根据声源位置对至少两个麦克风进行切换，以控制至少两个麦克风中的部分麦克风作为主麦克风来接收所述声源位置发出的第一声音信号，可选声源判断模块根据耳廓图像确定移动终端与用户的设置方向，并根据设置方向确定声源位置，切换模块将距离声源位置最近的部分麦克风作为主麦克风。与现有需要辨识移动终端的方向再进行通讯的技术相比，本发明的移动终端在接通来电时，通过判断用户的声源位置以控制至少两个麦克风中的部分麦克风接收用户的声音信号，进而实现无需手动辨识移动终端的方向，使得用户便捷的进行清晰、准确的通话。
以上参照附图说明了本发明的优选实施例，并非因此局限本发明的权利范围。本领域技术人员不脱离本发明的范围和实质内所作的任何修改、等同替换和改进，均应在本发明的权利范围之内。
