Description

控制终端的多麦克风降噪的拾音范围的方法和装置
本申请要求于2015年10月20日提交中国专利局，申请号为201510689091.9发明名称为“控制终端的多麦克风降噪的拾音范围的方法和装置”的中国专利申请，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及终端技术领域，特别涉及一种控制终端的多麦克风降噪的拾音范围的方法和装置。
背景技术
为了过滤手机传递给对端用户声音中的噪声，大部分手机设置有多个麦克风，并利用多麦克风降噪，处理多个麦克风采集的多路麦克风输入信号，得到一路上行输出信号，多麦克风降噪处理通常相当于在手机附近形成具有一定几何形状的拾音范围，采集该拾音范围内的用户上行语音，而抑制该拾音范围外的环境噪声。比如一种典型的两个麦克风方案的布局是一个麦克风设置在手机的顶端附近，主要用于采集环境噪声；另一个麦克风设置在手机的底部，采集包含环境噪声的用户声音。手机利用多麦克风降噪处理两路麦克风输入信号，将包含环境噪声的用户声音中的环境噪声消除，得到较纯净的用户声音，将用户声音传递给对端。
从拾音范围是否是固定的角度，可以将多麦克风降噪分为两类。固定的拾音范围效果比较稳定，但当用户手持姿势异常，比如机身大角度偏离用户脸部时，有可能因为用户嘴巴偏出固定的拾音范围而导致上行无声，或声音小，或音质差。简单设置较大的拾音范围通常会减弱对环境噪声的滤除效果。为了在上行降噪效果和对用户手持姿势的适应能力之间取得更好的平衡，目前有一些多麦克风降噪方案会利用麦克风采集的语音通话频段信号对用户的手持姿势做出估计，并据此控制手机的多麦克风降噪的拾音范围，从而在用户手持姿势正常时以较小的拾音范围尽可能滤除环境噪声，而当手持姿势出现异常时扩大拾音范围，避免对用户上行语音的音量或音质造成明显负面影响。
在实现本发明的过程中，发明人发现现有技术至少存在以下问题：
通过语音频段的信号对用户手持姿势的估计容易受到环境噪声的影响，从 而导致控制多麦克风降噪的拾音范围的准确性低。

步骤102：根据第一非语音信号和第二非语音信号，确定用户通话时手持终端的姿势是否为正常姿势；
步骤103：如果用户通话时手持终端的姿势不是正常姿势，调整终端的多麦克风降噪的拾音范围。
在本发明实施例中，发射第一非语音信号，并接收第一非语音信号被反射物体反射回来的第二非语音信号，根据第一非语音信号和第二非语音信号，确定用户通话时手持终端的姿势是否为正常姿势；如果用户通话时手持终端的姿势不是正常姿势，调整终端的多麦克风降噪的拾音范围，由于本发明是通过非语音信号，调整终端的多麦克风降噪的拾音范围，因此不会受环境噪声的影响，可以提高调整终端的多麦克风降噪的拾音范围的准确性。
本发明实施例提供了一种控制终端的多麦克风降噪的拾音范围的方法，该方法的执行主体为终端，参见图2-1，其中，该方法包括：
步骤201：发射第一红外光信号，并获取第一红外光信号的第一光线强度；
参见图2-2，该终端上设置有两个接近光传感器，为了便于描述，将两个接近光传感器分别称为第一接近光传感器和第二接近光传感器；其中，第一接近光传感器可以为终端上现有的位于终端的听筒旁边的接近光传感器，第二接近 光传感器可以设置在终端的正面且终端屏幕的下方。参见图2-3，第二接近光传感器也可以设置在终端的顶端。
进一步地，为了提高控制终端的多麦克风降噪的拾音范围的准确性，也可以结合第二接近光传感器，检测用户通话时手持终端的姿势，则在本步骤中，第二接近光传感器发射第三红外光信号，并获取第三红外光信号的第三光线强度。
当用户在打电话或者接听电话时，用户会手持终端靠近用户的耳朵，因此，第一接近光传感器发射的第一红外光信号会被用户的头部反射回去，第二接近光传感器发射的第三红外光信号也会被用户的头部发射回去，为了便于描述，将第一红外光信号被用户的头部反射回去得到的红外光信号称为第二红外光信号，将第三红外光信号被用户的头部发射回去得到的红外光信号称为第四红外光信号，执行步骤202。
步骤202：接收第一红外光信号被反射物体反射回来的第二红外光信号，并获取第二红外光信号的第二光线强度；
进一步地，第二接近光传感器接收第四红外光信号，并获取第四红外光信号的第四光线强度。
当用户通话时手持终端靠近用户的耳朵时，反射物体可以为用户的头部。
步骤203：计算第二光线强度和第一光线强度之间的第一强度差；
进一步地，如果第二接近光传感器发射第三红外光信号，并接收第三红外光信号被反射物体反射回来的第四红外光信号，则在本步骤中还需要计算第四光线强度和第三光线强度之间的第二强度差。
步骤204：根据第一强度差，确定用户通话时手持终端的姿势是否为正常姿势；
参见图2-4，正常姿势即为终端的上端贴近用户的耳朵，且终端的下端与用户的脸之间的夹角小于预设角度。
本步骤可以通过第一种方式、第二种方式、第三种方式或者第四种方式实现；当终端只通过第一接近光传感器检测用户通话时手持终端的姿势时，可以通过以下第一种方式或者第二种方式实现；当终端结合第一接近光传感器和第二接近光传感器检测用户通话时手持终端的姿势时，可以通过以下第三种方式或者第四种方式实现。
对于第一种实现方式，本步骤可以为：
确定第一强度差是否大于第一预设强度，如果第一强度差大于第一预设强度，确定用户通话时手持终端的姿势不是正常姿势。
如果第一强度差大于第一预设强度，确定第一接近光传感器离发射物体较远，也即用户通话时手持终端的上端没有贴近用户的耳朵，从而确定用户通话时手持终端的姿势不是正常姿势。
用户通话时手持终端的姿势不是正常姿势时，用户通话时手持终端的姿势可能为外翻姿势或者外扩姿势等；参见图2-5，外翻姿势即为用户通话时手持终端的上端贴近用户的耳朵，且终端的下端与用户的脸之间的夹角大于预设角度。参见图2-6，外扩姿势即为用户通话时手持终端的上端没有贴近用户的耳朵，且终端的下端与用户的脸之间的夹角大于预设角度。
预设角度和第一预设强度可以根据需要进行设置并更改，在本发明实施例中，对预设角度和第一预设强度不作具体限定。
对于第二种实现方式，本步骤可以为：
根据第一强度差，计算第一接近光传感器与反射物体之间的第一距离；如果第一距离大于第一预设距离，确定用户通话时手持终端的姿势不是正常姿势。
根据第一强度差，从强度差和距离的对应关系中获取第一强度差对应的距离，将该距离确定为第一接近光传感器与反射物体之间的第一距离。如果第一距离大于第一预设距离，确定用户通话时手持终端的上端没有贴近用户的耳朵，从而确定用户通话时手持终端的姿势不是正常姿势。
第一预设距离可以根据需要进行设置并更改，在本发明实施例中，对第一预设距离不作具体限定；例如，第一预设距离为0.8厘米或者1厘米等。
对于第三种实现方式，当第二接近光传感器设置在终端的正面且终端屏幕的下方时，结合第一接近光传感器和第二接近光传感器，确定用户通话时手持终端的姿势是否为正常姿势，包括：
计算第四光线强度和第三光线强度之间的第二强度差，确定第一强度差是否大于第一预设强度，以及确定第二强度差是否大于第二预设强度；如果第一强度差大于第一预设强度，或者第二强度差大于第二预设强度，确定用户通话时手持终端的姿势不是正常姿势；如果第一强度差不大于第一预设强度且第二强度差不大于第二预设强度，确定用户通话时手持终端的姿势是正常姿势。
对于第四种实现方式，终端也可以通过第一接近光传感器与反射物体之间的第一距离以及第二接近光传感器与反射物体之间的第二距离，确定用户通话时手持终端的姿势是否为正常姿势，包括：
计算第四光线强度和第三光线强度之间的第二强度差，根据第一强度差，计算第一接近光传感器与反射物体之间的第一距离，以及根据第二强度差，计算第二接近光传感器与反射物体之间的第二距离；确定第一距离是否大于第一预设距离，以及确定第二距离是否大于第二预设距离；如果第一距离大于第一预设距离，或者第二距离大于第二预设距离，确定用户通话时手持终端的姿势不是正常姿势；如果第一距离不大于第一预设距离且第二距离不大于第二预设距离，确定用户通话时手持终端的姿势是正常姿势。
其中，根据第一强度差，计算第一接近光传感器与发射物体之间的第一距离，以及根据第二强度差，计算第二接近光传感器与反射物体之间的第二距离的步骤可以为：
根据第一强度差和第二强度差，从强度差和距离的对应关系中获取第一强度差对应的距离以及第二强度差对应的距离；将第一强度差对应的距离确定为第一接近光传感器与发射物体之间的第一距离，将第二强度差对应的距离确定为第二接近光传感器与发射物体之间的第二距离。
需要说明的是，当第二接近光传感器设置在终端的顶端，当用户通话时手持终端的姿势为正常姿势，此时第三红外光信号可能不被用户的头部反射回去，此时检测第三光线强度之后的预设时长内是否接收到第四红外光信号；如果在第三光线强度之后的预设时长内没有接收到第四红外光信号，且第一强度差小于第一预设强度，确定用户通话时手持终端的姿势是正常姿势；或者，如果在第三光线强度之后的预设时长内没有接收到第四红外光信号，且第一距离小于第一预设距离，确定用户通话时手持终端的姿势是正常姿势。
进一步地，当第二接近光传感器设置在终端的顶端，如果在第三光线强度之后的预设时长内接收到第四红外光信号，确定用户通话时手持终端的姿势不是正常姿势。
第二预设强度、第二预设距离和预设时长可以根据需要进行设置并更改，在本发明实施例中，对第二预设强度、第二预设距离和预设时长不作具体限定。
如果用户通话时手持终端的姿势不是正常姿势，执行步骤205。
步骤205：如果用户通话时手持终端的姿势不是正常姿势，调整终端的多麦克风降噪的拾音范围。
如果用户通话时手持终端的姿势不是正常姿势，为了保证用户在通话过程中，即使用户手持终端的姿势为外翻姿势或者外扩姿势，依然可以得到清晰的上行语言，可以增大终端的多麦克风降噪的拾音范围。
进一步地，为了更准确地调整终端的多麦克风降噪的拾音范围，可以将终端的多麦克风降噪的拾音范围设置为用户通话时手持终端的姿势获取拾音范围，则终端中存储姿势和拾音范围，如果用户通话时手持终端的姿势不是正常姿势时，根据非正常姿势，从姿势和拾音范围的对应关系中获取与非正常姿势相匹配的拾音范围，将终端的多麦克风降噪的拾音范围设置为与非正常姿势相匹配的拾音范围。
进一步地，如果第二接近光传感器设置在终端的正面且终端屏幕的下方时，当用户通话时手持终端的姿势不是正常姿势时，可以获取用户通话时手持终端的外翻角度，根据该外翻角度，调整终端的多麦克风降噪的拾音范围，则本步骤可以为：
根据第一距离、第二距离以及第一接近光传感器和第二接近光传感器之间的第三距离，计算用户通话时手持的终端与反射物体之间的夹角，将该夹角确定为用户通话时手持终端的外翻角度，获取与该外翻角度相匹配的拾音范围，将终端的多麦克风降噪的拾音范围调整为与该外翻角度相匹配的拾音范围。
终端中存储有外翻角度范围和拾音范围的对应关系，相应的，终端获取与该外翻角度相匹配的拾音范围的步骤可以为：
终端根据该外翻角度，确定该外翻角度所在的外翻角度范围，根据该外翻角度所在的外翻角度范围，从外翻角度范围和拾音范围的对应关系中获取与该外翻角度相匹配的拾音范围。
进一步地，如果用户通话时手持终端的姿势是正常姿势，终端根据正常姿势，从姿势和拾音范围的对应关系中获取与正常姿势相匹配的拾音范围，将终端的多麦克风降噪的拾音范围调整为与正常姿势相匹配的拾音范围。
在本发明实施例中，发射第一红外光信号，并接收第一红外光信号被反射物体反射回来的第二红外光信号，根据第一红外光信号和第二红外光信号，确定用户通话时手持终端的姿势是否为正常姿势；如果用户通话时手持终端的姿 势不是正常姿势，调整终端的多麦克风降噪的拾音范围，由于本发明是通过光信号，调整终端的多麦克风降噪的拾音范围，因此不会受环境噪声的影响，可以提高调整终端的多麦克风降噪的拾音范围的准确性。
本发明实施例提供了一种控制终端的多麦克风降噪的拾音范围的方法，该方法的执行主体为终端，参见图3-1，其中，该方法包括：
步骤301：发射第一高频超声信号，接收第一高频超声信号被反射物体反射回来的第二高频超声信号；
终端中有听筒，听筒发射第一高频超声信号，第一高频超声信号的频率大于用户的耳朵感知的声音的频率，从而用户的耳朵无法感知第一高频超声信号，因此，不会对用户造成干扰。
参见图3-2，终端上至少有两个麦克风，为了便于描述，将终端上的麦克风称为第一麦克风和至少一个第二麦克风；第一麦克风可以设置在终端的底部，用于采集包含环境噪声的用户声音；至少一个第二麦克风可以设置在终端的顶部，用于采集环境噪声。终端利用多麦克风降噪，处理两路麦克风输入信号，将包含环境噪声的用户声音中的环境噪声消除，得到较纯净的用户声音，将用户声音传递给对端。

需要说明的是，传递函数是现有概念，在此不再对传递函数进行详细说明。
步骤303：根据第一传递函数，确定用户通话时手持终端的姿势是否为正常姿势；
正常姿势即为用户通话时手持终端的上端贴近用户的耳朵，且终端的下端与用户的脸之间的夹角小于预设角度。

第一预设相似度可以根据需要进行设置并更改，在本发明实施例中对第一预设相似度不作具体限定；例如，第一预设相似度可以为0.6或者0.8等。
对于第二种实现方式，本步骤可以通过以下步骤(A)至(D)实现，包括：
(A)：根据第一高频超声信号和第二高频超声信号，获取第一高频超声信号从终端的听筒到至少一个第二麦克风的第二传递函数，得到至少一个第二传递函数；
(B)：计算第一传递函数与正常姿势对应的传递函数之间的第一相似度以及至少一个第二传递函数中的每个第二传递函数与正常姿势对应的传递函数之 间的第二相似度，得到至少一个第二相似度；
(C)：根据第一相似度和至少一个第二相似度，计算综合相似度；
获取第一相似度对应的第一权重以及至少一个第二相似度中的每个第二相似度对应的第二权重，根据第一相似度、第一权重、每个第二相似度和每个第二相似度对应的第二权重，计算综合相似度；或者，

(3)：将选择的传递函数对应的外翻角度确定为用户通话时手持终端的外翻角度。
步骤305：根据该外翻角度，调整终端的多麦克风降噪的拾音范围。
如果用户通话时手持终端的姿势不是正常姿势，为了保证用户在通话过程中，即使用户手持终端的姿势为外翻姿势或者外扩姿势，依然可以得到清晰的上行语言，可以增大终端的多麦克风降噪的拾音范围。
进一步地，为了更准确地调整终端的多麦克风降噪的拾音范围，可以将终 端的多麦克风降噪的拾音范围设置为与该外翻角度相匹配的拾音范围，则终端中存储有外翻角度和拾音范围的对应关系，则本步骤可以为：
