具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
图1A示例性示出了本申请涉及的无线音频系统。该无线音频系统可包括电子设备100.无线耳机200。其中，无线耳机200可包括左耳机201和右耳机202。
左耳机201和右耳机202之间可以没有线缆连接。二者可以通过无线通信连接103而不是有线通信连接，进行通信。例如，左耳机201和右耳机202可分别为一副真无线立体声(true wireless stereo，TWS)耳机的左耳.右耳。
在该无线音频系统中，左耳机201、右耳机202可分别和电子设备100建立无线通信连接。例如，左耳机201可以和电子设备100之间建立无线通信连接101，可通过无线通信连接101交互音频数据.播放控制消息、通话控制消息等。同样的，电子设备100和右耳机202之间可以建立无线通信连接102，并可以通过无线通信连接102交互音频数据.播放控制消息、通话控制消息等。
图1A所示的无线音频系统可以是基于蓝牙协议实现的无线音频系统。即电子设备100.左耳机201和右耳机202之间的无线通信连接(如无线通信连接101、无线通信连接102、无线通信连接103)可以采用蓝牙通信连接。
不限于蓝牙，无线耳机200与电子设备100之间的通讯方式还可以为其他，例如无线高保真(wireless fidelity，Wi-Fi)、Wi-Fi直连(Wi-Fi direct)、蜂窝移动通讯方式等。
需要说明的是，本申请实施例中的电子设备100以手机为例，电子设备100还可以是手表.平板电脑.个人电脑等，在此不作限定。
图1A示例性示出了无线音频系统中的左耳机201、右耳机202的结构。其中，左耳机201、右耳机202均可包括：音频模块.通信模块和传感器。音频模块可用于将音频数据转换成声音，具体可为电声转换器(electro-acoustic transducer)。通信模块可用于与其他设备，如电子设备100，进行通信。通信模块可以是蓝牙模块，也可以是Wi-Fi等其他通信类型的通信模块。传感器可包括加速度传感器、陀螺仪传感器和红外传感器等，其中，加速度传感器和陀螺仪传感器具体可用于检测左耳机201或右耳机202的运动姿态，例如移动位移、旋转角度等，红外传感器具体可用于检测左耳机201或右耳机202的入耳状态，例如是否被用户佩戴入耳。
左耳机201、右耳机202中的音频模块.通信模块和传感器都耦合到处理器，处理器可负责读取存储器中的指令，对指令译码并执行指令，以实现本申请提供的耳机佩戴错误识别方法在耳机侧的步骤。在本申请提供的耳机佩戴错误识别方法中，左耳机201或右耳机202可以将检测到的耳机的运动姿态，例如移动位移、旋转角度等，并可将该运动姿态报告至电子设备100。如图2所示，电子设备100可通过该通信模块和耳机通信，接收耳机报告的关于耳机的运动姿态的信息以及耳机电量信息等等，并可通过处理器分析耳机的运动姿态等，还可通过屏幕输出提示信息，以提示耳机剩余电量等。
不限于图2所示，左耳机201、右耳机202还可以包括其他部件，例如受话器、指示灯等。本申请对左耳机201、右耳机202的物理形态、尺寸等不作限制。如图1B所示，无线耳机200还可配置有左耳机201、右耳机202的收纳盒203，收纳盒203可用于收纳左耳机201、右耳机202，甚至可以为左耳机201、右耳机202提供充电功能，又可以称为耳机盒或充电盒。收纳盒203可以是独立于其他电子设备，也可以集成于其他电子设备中，例如在手机或智能手表等穿戴设备中设计的用于收纳耳机的部件。如图1B所示，耳机(如右耳)可包括耳塞和杆体这两个主体结构，其中，耳塞入耳的部分导出有管嘴，管嘴上一般布有一层细网，杆体的尺寸可大可小，杆体的形态也可以多种多样。可选的，左耳机、右耳机可以不包括杆体。在不包括杆体的左耳机，右耳机的设计方式中，可以将左、右耳机设置为相同的外形。
本申请实施例提供了一种耳机佩戴错误识别方法，基于耳机的传感器(例如加速度传感器、陀螺仪传感器、磁场检测传感器等)检测耳机佩戴动作，电子设备可以根据该耳机佩戴动作确定出左、右耳机是否佩戴错误。一旦确定左右耳佩戴错误，电子设备可以通过屏幕输出提示信息，以提示用户左、右耳机佩戴错误。在左、右耳机佩戴错误的情况下，可选的，电子设备还可以自动进行左右耳模式切换，即使用户不手动切换左、右耳机，也不会影响音频输出所呈现的播放效果。这样，还可以支持耳机的小型化，不要求左、右耳机形态有区别。
耳机中的加速度传感器可以检测到耳机运动时的位移、加速度等移动值。耳机中的陀螺仪传感器可以检测到耳机运动时产生哪种旋转，以及相应的旋转值。本申请实施例将主要关注耳机在两种情况下产生的运动：用户佩戴耳机过程中(如拿起耳机塞入耳朵)的耳机运动， 以及用户佩戴好耳机后因用户头部运动而引起的耳机运动。在用户佩戴好耳机的情况下，用户头部旋转会引起被佩戴的耳机运动，该运动产生的位移、旋转值可分别被加速度传感器、陀螺仪传感器检测到。为了提高测量的准确度，除了加速度传感器、陀螺仪传感器，还可以结合磁场检测传感器，甚至定位传感器等来辅助检测耳机运动。
图3、图4分别示出了典型的人头部旋转、耳机旋转，其中坐标系O-XYZ可以是载体坐标系。载体坐标系以运动载体的质心为原点，一般根据运动载体自身结构方向构成坐标系。例如，对于人头部的载体坐标系，Y轴在由原点指向头部顶部的方向上，Z轴在由原点指向人脸前方的方向上，X轴在由原点指向左耳的方向上。对于耳机的载体坐标系，Y轴在由原点指向耳塞顶部的方向上，Z轴在由原点指向耳塞两侧的方向上，X轴在由原点指向耳嘴的方向上。
如图3所示，人头部运动时会产生三种旋转中的一种或多种，这三种旋转包括：绕Y轴的旋转，绕Z轴的旋转和绕X轴的旋转。绕Y轴旋转的旋转值可以称为偏航角(Yaw)，绕Z轴旋转的旋转值可以称为翻滚角(Roll)，绕X轴旋转的旋转值可以称为俯仰角(Pitch)。这几种旋转值又可以统称为姿态角或欧拉角。在图3中，Yaw为正值可表示用户向右转动头部，Yaw为负值可表示用户向左转动头部；Roll为正值可表示用户向左肩歪头，Roll为负值可表示用户向右肩歪头；Pitch为正值可表示用户向上抬头，Pitch为负值可表示用户向下低头。
如图4所示，耳机(图中以右耳机为例)运动时同样会产生三种旋转中的一种或多种。不同的是，耳机的这三种旋转的旋转值可以在更大范围内取值，例如旋转值为±180°，而人头部旋转的最大角度一般不能超出±90°。
用户从耳机盒取出耳机到戴上耳朵之前这一过程中的耳机运动(可简称为“佩戴中的耳机运动”)，体现了用户佩戴耳机的动作，可以用来判断耳机佩戴错误与否。下面进行说明。
1.佩戴中的耳机运动
以右耳机为例，下面比对耳机佩戴错误.耳机佩戴正确在佩戴中的耳机运动。
假设，右耳机的初始姿态如图5A所示，右耳机(right bud)的耳嘴的朝向和用户的右耳朵的朝向相对，左耳机(left bud)的耳嘴的朝向和用户的左耳朵的朝向相对。初始姿态可以是指从耳机盒中拿出右耳机时右耳机的姿态。图中的坐标系O-XYZ为人头部的载体坐标系。图5A所示的初始姿态可能是用户佩戴耳机时最常出现的，因为耳机的设计方基于用户体验的考虑更可能会提供这种情况的耳机佩戴体验，以便于用户佩戴耳机，这样用户无需旋转耳机来调整耳嘴的朝向，拿起右耳机便可以直接对准、戴入右耳朵，拿起左耳机便可以直接对准、戴入左耳朵。
图5B示例性示出了图5A所示情况下用户正确佩戴耳机过程中的耳机运动。右耳机可检测到右耳机绕Y轴的旋转角度很小(接近0°)，因为右耳机的耳嘴的朝向和用户的右耳朵的朝向相对，用户无需调整耳嘴的朝向便可将右耳机对准、戴入右耳朵。
图5C和图5D示例性示出了图5A所示情况下用户错误佩戴耳机过程中的耳机运动。图5C所示耳机佩戴过程中，右耳机可检测到右耳机绕Y轴顺时针旋转180°，因为右耳机的耳嘴的朝向和用户的右耳朵的朝向没有相对，用户需要旋转右耳机半圈左右，以将右耳机的耳嘴的朝向调整到和用户的右耳朵的朝向相对。图5D所示耳机佩戴过程中，右耳机可检测到右耳机绕Y轴逆时针旋转180°
从图5A-图5D可以看出，对于具有图5A所示初始姿态的右耳机，正确佩戴耳机的动作和错误佩戴耳机的动作是不一样的，如绕Y轴旋转角度不一样，这样就可以区分出错误佩戴 耳机的动作。
耳机内的运动传感器(如陀螺仪传感器)可检测耳机是否发生了绕Y轴的旋转。绕Y轴旋转角度可以是指累积旋转角度，即耳机从耳机盒中被拿出来到戴入用户耳朵这一过程中绕Y轴累积所旋转的角度。这一过程中，相反方向的旋转角度会发生抵消，例如耳机先绕Y轴转动+90°，再绕Y轴转动-90°，那累积旋转角度为0°。在正确佩戴右耳机或错误佩戴右耳机的过程中，右耳机也可能发生绕X轴、绕Z轴旋转的情况。而右耳机佩戴错误与否主要可通过绕Y轴旋转情况来判断，因为右耳机佩戴错误与否主要取决于右耳机的耳嘴的朝向和用户的右耳朵的朝向是否相对，而是否相对这一点可主要参考右耳机绕Y轴的旋转情况来分析。
不限于图5A所示的初始姿态，初始姿态还可以为其他，例如如图6A所示，用户打开耳机盒，右耳机(right bud)的耳嘴的朝向和用户的左耳朵的朝向相对，左耳机(left bud)的耳嘴的朝向和用户的右耳朵的朝向相同。图6A所示情况一般可能发生在用户拿反了耳机盒的前提下，当然也不排除耳机设计方提供的佩戴体验就是这样的。
图6B和图6C示例性示出了图6A所示情况下用户正确佩戴耳机过程中的耳机运动。图6B所示耳机佩戴过程中，右耳机可检测到右耳机绕Y轴逆时针旋转180°，因为右耳机的耳嘴的朝向和用户的右耳朵的朝向没有相对，用户需要旋转右耳机半圈左右，以将右耳机的耳嘴的朝向调整到和用户的右耳朵的朝向相对。图6C所示耳机佩戴过程中，右耳机可检测到右耳机绕Y轴顺时针旋转180°
图6D示例性示出了图6A所示情况下用户错误佩戴耳机过程中的耳机运动。图6D所示耳机佩戴过程中，右耳机可检测到右耳机绕Y轴的旋转角度很小(接近0°)，因为右耳机的耳嘴的朝向和用户的左耳朵的朝向相对，用户无需调整耳嘴的朝向便可将右耳机对准、戴入右耳朵。
从图6A-图6D可以看出，对于具有图6A所示初始姿态的右耳机，正确佩戴耳机的动作和错误佩戴耳机的动作是不一样的，如绕Y轴旋转角度不一样，这样就可以区分出错误佩戴耳机的动作。
在陀螺仪检测到的旋转值(如绕Y轴旋转值)的基础上，还可以进一步结合更多耳机运动特征，例如通过加速度计等检测到的耳机的移动值(如加速度、位移等)，以更精准的描述耳机佩戴动作。当然，移动值也可单独用来识别耳机佩戴错误与否，具体可通过限定移动方向，以及移动距离来实现。下面依然以图5A-图5D、图6A-图6D所示佩戴过程为例来进行说明。
图5B示例性示出了图5A所示情况下用户正确佩戴耳机过程中的耳机运动。右耳机相对于起始位置(其坐标可定义为(0,0,0))产生的移动值可以通过运动数据组合(X-，Y+，Z-)来表示。其中，“X-”表示右耳机在X轴负向上移动，表示右耳机在X轴上靠近右耳朵运动，即朝人脸右侧运动；“Y+”表示右耳机在Y轴正向上移动，表示右耳机被拿起向上；“Z-”表示右耳机在Z轴负向上移动，表示右耳机被用户拿近身前。
图5C和图5D示例性示出了图5A所示情况下用户错误佩戴耳机过程中的耳机运动。图5C所示耳机佩戴过程中，右耳机相对于起始位置(其坐标可定义为(0,0,0))产生的移动值可以通过运动数据组合(X+，Y+，Z-)来表示。其中，“X+”表示右耳机在X轴正向上移动，表示右耳机在X轴上靠近左耳朵运动，即朝人脸左侧运动；“Y+”表示右耳机在Y轴正向上移动，表示右耳机被拿起向上；“Z-”表示右耳机在Z轴负向上移动，表示右耳机被用户拿近身前。图5D所示耳机佩戴过程中，右耳机相对于起始位置产生的移动值也可以通过运动数 据组合(X+，Y+，Z-)来表示。
图6B和图6C示例性示出了图6A所示情况下用户正确佩戴耳机过程中的耳机运动。图6B所示耳机佩戴过程中，右耳机相对于起始位置(其坐标可定义为(0,0,0))产生的移动值可以通过运动数据组合(X-，Y+，Z-)来表示。其中，“X-”表示右耳机在X轴负向上移动，表示右耳机在X轴上靠近右耳朵运动，即朝人脸右侧运动；“Y+”表示右耳机在Y轴正向上移动，表示右耳机被拿起向上；“Z-”表示右耳机在Z轴负向上移动，表示右耳机被用户拿近身前。图6C所示耳机佩戴过程中，右耳机检测到的耳机运动也可以通过运动数据组合(X-，Y+，Z-)来表示。
图6D示例性示出了图6A所示情况下用户错误佩戴耳机过程中的耳机运动。右耳机相对于起始位置(其坐标可定义为(0,0,0))产生的移动值可以通过运动数据组合(X+，Y+，Z-)来表示。其中，“X+”表示右耳机在X轴正向上移动，表示右耳机在X轴上靠近左耳朵运动，即朝人脸左侧运动；“Y+”表示右耳机在Y轴正向上移动，表示右耳机被拿起向上；“Z-”表示右耳机在Z轴负向上移动，表示右耳机被用户拿近身前。
上述由XYZ轴上的移动值组成的各个运动数据组合，需要在右耳机相对于用户的初始姿态已知的情况下，利用右耳机内的加速度传感器的检测值计算出。如果第一耳机相对于用户的初始姿态具有多种可能性的情况下，例如图5A、图6A等多种可能情况，基于陀螺仪检测到的旋转来确定耳机佩戴是否错误，也需要在右耳机相对于用户的初始姿态已知的情况下才能实现。为了知道右耳机相对于用户的初始姿态，一种实现方式是，用户可以在耳机所通信的电子设备(如手机)上确认耳机的初始姿态为哪一种，即耳机从耳机盒中被取出时的姿态，例如耳嘴相对于用户的朝向。另一种实现方式是，可以根据耳机盒被用户握持的姿态确定该初始姿态为哪一种，例如耳机盒的推荐握持姿态通常便于用户取用耳机，提供如图5A所示的情况。
本申请实施例提供的技术方案也可以针对默认初始姿态(如图5A或图6A所示)来识别耳机佩戴是否错误，这对于左、右耳机初始姿态固定的场景是十分适用的，例如左、右耳机存放在集成于智能手表上的耳机盒中，用户每次抬起手腕取用耳机时，左、右耳机相对于用户的初始姿态是固定的。例如，假设默认初始姿态如图5A所示，如果检测到右耳机的旋转角度为180°左右，则可确定右耳机佩戴错误。可选的，可以根据位移来判断耳机是否佩戴错误，如，考虑到用户的正常使用情况，将耳机盒开口朝用户的方向作为耳机的默认初始位置，耳机中存储其正常从耳机盒取出佩戴到相应耳朵的位移，通过位移判断耳机是否佩戴正确。
耳机从耳机盒中被取出这一事件可以通过检测耳机与耳机盒内的充电金属件的分离来确定，也可以通过检测运动姿态来确定。如上所述，耳机从耳机盒中被取出，到耳机被戴上用户的耳朵，这期间通过陀螺仪.加速度计等传感器采集到的运动数据(如旋转角度、位移、加速度等)可用来描述用户佩戴耳机的动作，从而基于此识别出耳机佩戴是否错误。
在耳机被戴上用户的耳朵之后，耳机会随着用户头部动作而产生耳机运动。例如佩戴耳机后用户向下低头放置耳机盒，耳机会随着向下低头的头部运动而产生耳机运动。这些伴随用户头部动作而产生的耳机运动可被用来进一步校准耳机佩戴是否错误的判断结果。
2.佩戴后的耳机运动
在佩戴耳机后，可以利用耳机内的陀螺仪.加速度计等传感器采集到的运动数据(如旋转角度、位移、加速度等)来确定耳机运动，从而校准前面基于“佩戴中的耳机运动”而初步 作出的耳机佩戴是否错误的判断结果，这样可以进一步提升准确度。
以右耳机为例，下面结合图7A-图7B、图8A-图8B、图9A-图9B、图10A-图10B、图11A-图11B、图12A-图12B比对耳机佩戴错误.耳机佩戴正确的情况下佩戴后的耳机运动(随多种头部运动而产生)。坐标系O-XHYHZH为人头部的载体坐标系，坐标系O-XaYaZa、O-XbYbZb为右耳机的载体坐标系。

不限于上述几种典型头部运动，还可以利用其他头部运动来校准耳机佩戴错误与否的判断结果。
基于上述利用耳机运动判断耳机佩戴错误与否的实施例，下面结合图13说明本申请实施例提供的耳机佩戴错误识别方法的总体流程。
S101.电子设备和耳机建立蓝牙通信连接。
电子设备和耳机可以基于该蓝牙通信连接交互音频数据.播放控制消息、通话控制消息等。耳机还可以通过该蓝牙通信连接向电子设备传输电量等设备状态信息，这样电子设备就可以显示出耳机的电量等设备状态，便于用户了解耳机状态。不限于蓝牙通信连接，电子设备和耳机之间建立的连接也可以是其他通信连接，例如Wi-Fi直连连接.蜂窝移动通信连接等等。
电子设备可与左、右耳机分别建立通信连接，分别传输左、右声道的音频数据至左、右耳机。电子设备也可以只与其中一个耳机建立通信连接，电子设备可以将左右声道的音频数据都传输至该耳机，例如左耳机，由左耳机承担起音频数据转发(“路由”)的角色，由左耳机分离出右声道的音频数据并将该右声道的音频数据传输至右耳机。
S102.通过耳机中的陀螺仪.加速度计等传感器检测耳机运动，根据耳机运动判断耳机佩戴是否错误。
具体的，耳机可以检测耳机从耳机盒中被拿出到戴上用户耳朵这期间的耳机运动，该耳机运动(简称为“佩戴中的耳机运动”)可用来体现用户佩戴耳机的动作，可以用来初步判断耳机佩戴错误与否。这个初步判断可以由耳机所通信的电子设备(如智能手机、智能手表)来执行，这种情况下，耳机可以在检测到被用户佩戴时，向电子设备发送“佩戴中的耳机运动”。这个初步判断也可以由耳机来执行。
关于如何根据“佩戴中的耳机运动”判断耳机佩戴是否错误，可参考前述图5A-图5D和 图6A-图6D实施例，这里不再赘述。左耳机佩戴错误与否的方法可参考右耳机的处理方式，这里不再赘述。
S103.通过佩戴检测器(如红外传感器)检测到左、右耳机都被佩戴。
S104.在左、右耳机都被用户佩戴的情况下，如果初步判断出耳机佩戴错误，则电子设备可以显示图14A-图14B所示的提醒，以提醒用户左、右耳机佩戴错误，这样用户就可以手动切换左右耳机。
在左、右耳机都被用户佩戴的情况下，如果初步判断出耳机佩戴错误，但用户不手动切换左、右耳机，则电子设备可以自动切换左、右声道，即将左声道的音频数据传输至右耳机播放，将右声道的音频数据传输至左耳机播放。
例如，如图14A-图14B所示，电子设备还可以提醒用户切换左右声道，可在检测到用户点击“切换”按钮时切换左右声道，这样用户不必手动切换左、右耳机也能享受到左右声道正确的音频播放效果。
可选的，电子设备也可以不提醒用户左、右耳机佩戴错误.手动切换左右耳机，而直接进行左、右声道的切换。
在左、右耳机都被用户佩戴的情况下，如果初步判断出耳机佩戴错误，则还可以利用“佩戴后的耳机运动”进一步校准耳机佩戴是否错误的判断结果。“佩戴后的耳机运动”伴随用户头部动作而产生。如果校准后的依然确认耳机佩戴错误，则再提醒用户进行左、右耳机的手动切换，或者无需手动切换左、右耳机而直接切换左右声道。
关于如何根据“佩戴后的耳机运动”校准耳机佩戴是否错误的判断结果，可参考前述图7A-图7B、图8A-图8B、图9A-图9B、图10A-图10B、图11A-图11B、图12A-图12B实施例，这里不再赘述。
不限于与基于佩戴中的耳机运动初步判断耳机佩戴错误与否的方案相结合，也可单独基于佩戴后的耳机运动来识别耳机佩戴是否错误。如果右耳机在佩戴后的耳机运动，例如耳机旋转、耳机位移等，与图7B、图8B、图9B、图10B、图11B、图12B示例性所示的错误佩戴右耳机后的耳机运动相符，则可确定右耳机被错误佩戴到用户的左耳朵上。
切换左右声道可以由电子设备来执行，也可以由耳机来执行。在一种情况下，电子设备可以将左右声道的音频数据都传输至左、右耳机中的某个耳机，例如左耳机，由左耳机承担起音频数据转发(“路由”)的角色，由左耳机分离出右声道的音频数据并将该右声道的音频数据传输至右耳机。在这种情况下，左耳机便可执行左右声道切换。
本申请实施例提供的耳机佩戴错误识别方法不仅可以识别出双耳佩戴错误，在双耳佩戴错误的情况下提供左右声道切换的功能，还可以识别出单耳佩戴错误。单耳佩戴错误的识别也具有重要意义，可避免用户出现佩戴不适的问题。
另外，还可以检测左、右耳机在耳机盒内的放置错误。在用户使用完耳机放置回耳机盒时，能够判断出左、右耳机放置错误与否，在放置错误的情况下进行左、右耳机模式切换，不需要用户手动切换左、右耳机放置位置，避免下次取用左、右耳机时出现耳机佩戴错误的风险。可选的，耳机可以向电子设备发送信息，在电子设备上显示提示信息指示用户进行耳机的切换，或，提示用户是否通过电子终端控制耳机执行左、右耳机模式切换。
这里，模式切换是指左、右耳机的角色发生切换，当用户再次取用耳机时，左耳机变成了右耳机，右耳机变成了左耳机，各自可在与电子设备建立连接时向电子设备报告新角色，以使得电子设备基于该新角色分发左右声道的音频数据，进而保障用户下次使用耳机时左右 声道是正确的。
一种实现中，左、右耳机在耳机盒内的放置错误可以通过耳机盒内或耳机上的充电金属件来实现。例如，耳机盒内包括分别容纳左、右耳机的第一腔体、第二腔体，第一腔体中设有默认为右耳机充电的充电金属件，第二腔体中设有默认为左耳机充电的充电金属件。相应的，第一耳机、第二耳机上也分别具有充电金属件，可用来与各自腔体内的充电金属件接触而获得耳机盒的充电。耳机盒可以通过该充电金属件读取各个腔体内放置的是左耳机还是右耳机，或耳机可以通过耳机上的充电金属件读取该耳机所处的腔体是哪一个腔体，从而判断出左、右耳机是否放置错误。一旦判断出耳机放置错误，则耳机盒可以与耳机通信以切换左、右耳机模式。
不限于充电金属件，耳机盒的第一腔体、第二腔体还可分别设置有近场通信器件、激光收发器或红外收发器等，这些器件也可以用来检测是否有耳机放置在腔体内以及识别放置在各自腔体内的耳机是左耳机还是右耳机，因此也能用于检测耳机放置错误与否。相应的，左、右耳机也可以分别具有充电金属器件、近场通信器件、激光收发器或红外收发器等，并可通过这些器件与第一腔体、第二腔体内的相应通信器件进行通信，从而检测耳机是否放置在腔体内以及识别放置在哪一个腔体内，因此也能用于检测耳机放置错误与否。
另一种实现中，耳机在耳机盒内的放置错误还可以基于用户取下耳机放回耳机盒的用户动作来识别耳机放置错误与否。该用户动作可以通过用户摘下耳机放回耳机盒过程中的耳机运动来体现。
其中，用户摘下耳机可通过佩戴检测传感器检测到。耳机放回耳机盒可以通过第一腔体、第二腔体各自的充电金属器件、近场通信器件、激光收发器或红外收发器等检测到，也可以通过左、右耳机各自的充电金属器件、近场通信器件、激光收发器或红外收发器等检测到。
具体的，以右耳机为例，如果所述用户摘下右耳机放回耳机盒过程中右耳机的耳机运动与预设的特定运动相符，则可确定右耳机被错误放置到第二腔体中。其中，该预设的特定运动可以为用户摘下右耳机到错误放置到第二腔体过程中右耳机产生的耳机运动。
该预设的特定运动可以包括：右耳机绕自己的Y轴进行预设的特定旋转。一种情况，在摘下右耳机之前，如果右耳机被正确佩戴在用户的右耳朵上，则该预设的特定旋转的旋转角度等于180°或者接近180°，从而放置入耳机盒内时右耳机的耳嘴的朝向与用户的左耳朵的朝向相对。另一种情况，在摘下右耳机之前，如果右耳机被错误佩戴在用户的左耳朵上，则该预设的特定旋转的旋转角度等于0°或者接近0°，从而放置入耳机盒内时右耳机的耳嘴的朝向与用户的左耳朵的朝向相对。这两种情况的前提是，放置耳机到耳机盒内时用户握持耳机盒的姿态为推荐握持姿态，耳机盒的推荐握持姿态通常便于用户放置左、右耳机，用户摘下耳机后无需调整耳机耳嘴的朝向即可放入各自腔体内。
可选的，预设的特定的动作可以参考第一种佩戴中的耳机运动的逆过程来判断耳机是否放置错误，在此不做赘述。
本申请实施例提供的基于佩戴中的耳机运动来识别耳机佩戴错误与否的方案.基于佩戴后的耳机运动来识别耳机佩戴错误与否的方案，以及检测左、右耳机在耳机盒内的放置错误的方案，这三个方案可以单独实施例，也可以相互结合实施。如前所述，当基于佩戴后的耳机运动来识别耳机佩戴错误与否的方案和基于佩戴中的耳机运动来识别耳机佩戴错误与否的方案相结合时，可以进一步校准基于佩戴中的耳机运动来识别耳机佩戴错误与否的初步判断结果。如前所述，当检测左、右耳机在耳机盒内的放置错误的方案与前述两个识别耳机佩戴错误与否的方案相结合时，可以进一步避免因耳机放置错误而导致下次佩戴耳机错误的问题。
