【具体实施方式】
下面结合附图和实施例，对本申请作进一步的详细描述。特别指出的是，以下实施例仅用于说明本申请，但不对本申请的范围进行限定。同样的，以下实施例仅为本申请的部分实施例而非全部实施例，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它实施例，都属于本申请保护的范围。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请中的术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”、“第三”的特征可以明示或者隐含地包括至少一个该特征。本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。术语“包括”和“具有”以及它们任何变形，意 图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请一方面提供一种耳机1的佩戴位置的检测方法。该方法可以是由耳机1本身执行的，也可以是由与耳机1进行通信的电子设备执行，电子设备具体可以是手机、平板或者电脑，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。
如图1所示，图1示出了耳机一实施例佩戴在用户耳部EAR上的状态。耳机1可以是耳夹式耳机。如图1所示，耳机1包括用于插入用户(使用者)的耳甲腔E12的发声部100、用于抵接用户的耳后的抵接部300和连接于发声部100和抵接部300的耳挂200。在佩戴状态下，耳挂200可以绕过用户的耳轮E17，发声部100和抵接部300在使用者的耳轮E17两侧形成夹持状态，且发声部100位于耳甲腔E12内。
该发声部100为声音播放装置，其用于将电信号转换成声信号，并播放给佩戴者。该抵接部300与发声部100形成夹持状态，以便将整个耳机1夹持佩戴在使用者的耳部EAR上。抵接部300内可以设置有检测模块和存储模块。其中，检测模块用于获取耳机的佩戴位置，耳机的佩戴位置包括左耳和右耳。存储模块用于存储佩戴位置指示，其中佩戴位置指示用于指示分别用于表征所述耳机佩戴于左耳还是右耳。
一些实施例中，检测模块和存储模块也可以设置于发声部100内，或者检测模块和存储模块其中一者设置于发声部100内，另一者设置于抵接部300内，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。一些实施例中，该抵接部300内可以设置有电池、电路板等器件。当然，该抵接部300也可不设置电池，而将电池安装到发声部100中，在本领域技术人员容易理解的范围之内，此处不再赘述。
如图1所示，耳挂200具有沿耳挂200的长度方向设置的对称面A1。具体地，耳挂200的对称面A1是指沿耳挂200的长度方向设置的，且对称面A1两侧的耳挂200部分差异最小或者一致，即如果耳挂200是规则对称的，那么对称面A1两侧的耳挂200部分一致，如果耳挂200不是严格对称的，那么对称面A1两侧的耳挂200差异应该是各种划分方式里最小的，例如可以在垂直于对称面A1的平面上观察耳挂200的投影来区分差异的大小。当耳机处于比较理想的佩戴状态下时，对称面A1可以与水平面基本平行。需要说明的是，本申请所描述的“基本平行”允许正负15°的误差范围，容易理解的是，在用户的使用过程中，耳机可能在自身重力作用下发生滑动，使得对称面A1偏离水平面。
在一些实施中，耳机1可以是其它类型的既支持左耳佩戴又支持右耳佩戴的耳机。容易理解的是，图1所示的耳夹式耳机仅仅是一个示例，并不能理解为对本申请方案的限制。
如图2所示，图2是本申请所提供的检测方法一实施例的流程示意图。该检测方法可以包括以下步骤：
S100：以预定的检测周期，利用检测模块获取用于表征耳机的佩戴位置的预判断结果。
每一个检测周期对应产生一个预判断结果。其中，检测周期可以介于50ms-10s之间。举例而言，检测周期可以是50ms、100ms、300ms、500ms、1s、3s、5s、10s。检测模块用于检测耳机的佩戴位置，并输出用于表征耳机的佩戴位置的预判断结果，其中，预判断结果用于表征耳机佩戴于左耳还是右耳。
在一些实施例中，检测模块可以包括加速度传感器，此时，S100可以通过其所包括的如下步骤来实现：
S101：以预定的检测周期，基于加速度传感器所检测的至少一组加速度值获取用于表征耳机的佩戴位置的预判断结果。
加速度传感器内置有空间坐标系，包括X轴、Y轴、Z轴。X轴和Y轴可以均与对称面A1基本平行，Z轴可以与对称面A1基本垂直。需要说明的是，本申请所描述的“基本平行”和“基本垂直”允许正负15°的误差范围。加速度传感器可以检测耳机在X轴、Y轴、Z轴方向上的加速度分量。
在一些实施例中，在每个检测周期内，可以仅获取一组加速度值，基于该组加速度值获取预判断结果。在一些实施例中，在每个检测周期内，可以获取多组加速度值，基于多组加速度值获取预判断结果，有利于提高佩戴位置检测的准确性。
在一些实施例中，每组加速度值可以仅包括Z轴方向上的加速度分量，也就是说，可以仅利用Z轴方向上的加速度分量获取预判断结果。Z轴方向上的加速度分量的正负能够在一定程度上体现耳机的佩戴位置。
具体地，当耳机处于比较理想的佩戴状态下，用户的头部不存在竖直方向上的运动，且用户的头部基本直立时，由于指定坐标轴Z轴与对称面A1基本垂直，且耳机在佩戴状态下，对称面A1与水平面基本平行，此时，重力加速度与Z轴之间的夹角相对较小，使得Z轴方向上的加速度分量的绝对值与重力加速度的数值之间存在关联，使得Z轴方向上的加速度分量的绝对值处于预设阈值范围内。
也就是说，当Z轴方向上的加速度分量的绝对值处于预设阈值范围内时，可以认定头部不存在竖直方向上的运动，且基本直立。此时，Z轴方向上的加速度分量的正负可以有效的表征佩戴位置。举例而言，若假设耳机佩戴于左耳时Z轴向上，耳机佩戴于右耳时Z轴向下，当Z轴方向上的加速度分量为正时，说明耳机是佩戴于右耳的，当Z轴方向上的加速度分量为负时，说明耳机是佩戴于左耳的。类似的，若假设耳机佩戴于左耳时Z轴向下，耳机佩戴 于右耳时Z轴向上，当Z轴方向上的加速度分量为正时，说明耳机是佩戴于左耳的，当Z轴方向上的加速度分量为负时，说明耳机是佩戴于右耳的。
当Z轴方向上的加速度分量的绝对值未处于预设阈值范围时，则说明头部可能存在上下运动，或者头部可能处于倾斜状态，比如，用户处于平躺或者半躺状态，此时，Z轴方向上的加速度分量的正负无法有效的表征耳机的佩戴位置。
在一些实施例中，每组加速度值可以包括X轴方向上的加速度分量、Y轴方向上的加速度分量、以及Z轴方向上的加速度分量，以提高预判断结果的准确率，在本领域技术人员容易理解的范围之内，此处不再赘述。
在一些实施例中，S101具体可以通过其所包括的如下步骤实现：
S1011：将每个检测周期内所获得的至少一组加速度值输入经训练的神经网络模型，以获取预判断结果。
具体地，可以利用标定好的训练集对神经网络模型进行训练。比如，训练集可以包括多组加速度值，每组加速度值包括X轴方向上的加速度分量、Y轴方向上的加速度分量、以及Z轴方向上的加速度分量。在每个检测周期内，可以获取至少一组加速度值，并将其输入训练好的神经网络模型，以获取预判断结果。
在一些实施例中，在每个检测周期内，可以仅获取一组加速度值，将该组加速度值输入训练好的神经网络模型，神经网络模型经过卷积池化等运算即可产生预判断结果。在一些实施例中，在每个检测周期内，可以获取多组加速度值，将多组加速度值输入训练好的神经网络模型，增加输入的数据量，有利于提高预判断结果的准确性，从而提高佩戴位置检测的准确性。
当基于检测周期内获取的至少一个加速度值能够确定出耳机佩戴于左耳时，可以将预判断结果设置成用于表示左耳；当基于检测周期内获取的至少一个加速度值能够确定出耳机佩戴于右耳时，可以将预判断结果设置成表示右耳；当基于检测周期内获取的至少一个加速度值无法判断耳机的佩戴位置时，可以将预判断结果设置成表示未知状态。当预判断结果被设置成表示左耳或右耳时，可以认为预判断结果是有效的，即处于有效状态；当预判断结果被设置成表示未知状态时，可以认为预判断结果是无效的，即处于无效状态。
在一些实施例中，检测模块还可以进一步包括陀螺仪，当预判断结果处于未知状态时，还可以通过陀螺仪对预判断结果进行重置。具体地，如图3所示，图3是S100一实施例的流程示意图，在S101之后，S100还可以进一步包括：
S102：确定预判断结果是否处于有效状态，其中有效状态用于指示耳机佩戴于左耳和右耳中的一者。
S103：若否，则根据用户执行预设头部动作时陀螺仪所检测的角速度值对预判断结果进行重置。
陀螺仪可以与加速度传感器共用同一空间坐标系，用于检测耳机绕X轴转动、绕Y轴转动、绕Z轴转动的角速度分量。
预设头部动作可以是包括向左肩歪头的动作、向右肩歪头的动作、向左转头的动作、向右转头的动作、向上抬头的动作、或者向下低头的动作，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。
在预判断结果处于无效状态时，可以向用户发送语音提醒，来提醒用户执行预设头部动作，当然，也可以向用户发送其它形式的提醒，以使用户执行预设头部动作，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。
假设耳机佩戴于左耳时Z轴向上，X轴向右，Y轴向后，耳机佩戴于右耳时Z轴向下，X轴向左，Y轴向后。在这种情况下，若预设头部动作为向右转头，且陀螺仪检测到的绕Z轴转动的角速度值为正，说明耳机是佩戴于左耳的，可以将预判断结果重置为表示左耳。若预设头部动作为向右转头，且陀螺仪检测到的绕Z轴转动的角速度值为负，说明耳机是佩戴于右耳的，可以将预判断结果重置为表示右耳。
在一些实施例中，在用户执行预设头部动作时，陀螺仪还可以通过绕X、Y、Z三轴转动的角速度分量来确定耳机的佩戴位置，相比于上述实施例中通过单轴的转动确定耳机佩戴位置，通过三轴的角速度分量来判断能够进一步提升准确性，在本领域技术人员容易理解的范围之内，此处不再赘述。
在本实施例的方案中，在预判断结果处于无效状态时，根据用户执行预设头部动作时陀螺仪所检测的角速度值对预判断结果进行重置，有利于提高预判断结果的有效性，进而提高佩戴位置检测的准确性。
在一些实施例中，耳机的天线结构被设置为佩戴于左耳或右耳时，天线通信性能会产生差异。比如，天线的辐射性能通常具有一定的方向性，耳机在设计时，其辐射性能可能基于左耳进行优化的，在这种情况下，当耳机被佩戴于左耳时的通信性能参数，比如RSSI值(Received Signal Strength Indication，接收的信号强度指示)，会优于耳机被佩戴于右耳时的通信性能参数。此时，检测模块可以用于检测耳机的通信性能参数，从而获取用于表征耳机的佩戴位置的预判断结果。
在一些实施例中，耳机的喇叭能够发射超声波，而耳机佩戴于左耳或右耳时，耳机的麦克风接收到超声波的时刻，或者波形会有区别。此时，检测模块可以用于检测耳机的麦克风接收到超声波的区别，从而获取用于表征耳机的佩戴位置的预判断结果。
S200：基于预判断结果和耳机当前的佩戴位置指示的比较结果对佩戴位置指示进行实时更新，其中预判断结果和佩戴位置指示分别用于表征耳机佩戴于左耳还是右耳。
在一些实施例中，S200可以通过其所包括的如下步骤实现：
S201：响应于连续设置的预定数量的检测周期中，预判断结果有效且不同于佩戴位置指示的检测周期的数量大于或等于预设数量阈值，则将佩戴位置指示更新为预判断结果，其中预定数量大于或等于预设数量阈值。
其中，对于“连续设置的预定数量的检测周期”及“预设数量阈值”的具体数值，本申请不作限制，本领域技术人员可以根据实际需求进行选择。
举例而言，“连续设置的预定数量的检测周期”可以是指连续五个检测周期，“预设数量阈值”可以是三。假设当前的佩戴位置指示表征佩戴位置为左耳，若连续五个检测周期中，有三个或三个以上个检测周期的预判断结果为右耳，则将佩戴位置指示从左耳更新为右耳。若连续五个检测周期中，只有一个或两个检测周期的预判断结果为右耳，或者连续五个检测周期的预判断结果均为左耳，则不对佩戴位置指示进行更新。
本实施例的方案中，通过对连续多个检测周期的预判断结果进行权重判断，来确定是否对佩戴位置指示进行更新，有利于提高佩戴位置检测的准确性。
如图4所示，图4是S200一实施例的流程示意图，在一些实施例中，S200可以通过其所包括的如下步骤实现：
S202：响应于连续出现预判断结果有效且不同于佩戴位置指示的检测周期的计数值等于预设计数阈值，将佩戴位置指示更新为预判断结果，并重置计数值。
其中，对于“预设计数阈值”的具体数值，本申请不作限制，本领域技术人员可以根据实际需求进行选择。
举例而言，“预设计数阈值”可以是三。假设当前的佩戴位置指示表征的佩戴位置为左耳，在出现预判断结果为右耳时，开始计数，将计数值设为1，若下一检测周期的预判断结果为右耳，则将计数值设为2，若下下一检测周期的预判断结果为右耳，则将计数值设为3，此时，连续出现右耳的计数值为三次，将佩戴位置指示从左耳更新为右耳，并将计数值重置为0。
S203：响应于预判断结果有效且与佩戴位置指示相同或者预判断结果无效，则保持佩戴位置指示，并重置计数值。
举例而言，“预设计数阈值”可以是三。假设当前的佩戴位置指示为左耳，在出现预判断结果为右耳时，开始计数，将计数值设为1，若下一检测周期的预判断结果为左耳，则将计数值重置为0，并保持佩戴位置指示不变。
需要说明的是，步骤S202和S203之间，并无先后顺序之分。
本实施例的方案中，当连续出现预判断结果有效且不同于佩戴位置指示的检测周期的计数值等于预设计数阈值时对佩戴位置指示进行更新，有利于提高佩戴位置检测的准确性。
总的来说，本申请的方案与相关技术的区别之处在于，在耳机处于佩戴状态时，以预定的检测周期周期性地检测耳机的佩戴位置，并对耳机内存储的佩戴位置指示进行实时更新，相比于相关技术中的方案有利于降低误测的风险，提高佩戴位置检测的准确性。
需要说明的是，本申请所描述的检测方法可以在预设时间段内周期性地执行，比如，响应于耳机处于佩戴状态，开始计时，在预设时间段内(举例而言，预设时间段的时长可以在20s-60s之间，比如20s、30s、40s、50s、60s)周期性地的执行以上所描述的检测方法。
本申请所描述的“实时更新”是指，对佩戴位置指示的更新是在该预设时间段内持续进行的。举例而言，当耳机被放置在耳机盒内时，耳机盒可以为耳机设置佩戴位置指示，当耳机刚刚被用户佩戴上时，可以根据预判断结果对佩戴位置指示进行一次更新，随后，还会继续利用检测模块获取预判断结果，并根据预判断结果对当前的佩戴位置指示持续地进行更新。
如图5所示，图5是本申请所提供的检测方法另一实施例的流程示意图，在一些实施例中，该检测方法进一步包括：
S1：响应于耳机处于佩戴状态，开始执行检测方法，并开始计时。
在一些实施例中，也可以响应于耳机被从耳机盒中取出时，开始执行以上所描述的检测方法，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。
S2：在计时小于或等于预设时间阈值时，以第一检测频率执行检测方法。
关于“预设时间阈值”的具体数值，本申请不作限制，本领域技术人员可以根据实际需求进行选择。
S3：在计时大于预设时间阈值时，以第二检测频率执行检测方法，第一检测频率高于第二检测频率。
本实施例的方案中，在预设时间阈值以前，以较高的检测频率执行以上所描述的检测方法，在预设时间阈值以后，以较低的检测频率执行以上所描述的检测方法，有利于在保证佩戴位置检测的准确性的前提下，降低设备功耗。
如图6所示，图6是本申请所提供的检测方法另一实施例的流程示意图，在一些实施例中，在S200之后，该检测方法进一步包括：
S300：根据佩戴位置指示为耳机适配对应声道的音频信号，和/或，根据佩戴位置指示设置耳机的按键功能。
举例而言，当佩戴位置指示表征耳机佩戴于左耳时，可以为耳机适配左声道的音频信号；类似地，当佩戴位置指示表征耳机佩戴于右耳时，可以为耳机适配右声道的音频信号，从而 提高用户的使用体验。
在一些实施例中，耳机上进一步设置有按键，按键可以是机械按键。也可以是触摸式按键。耳机佩戴于左耳或者右耳时，其按键功能可能是不同的。比如，当耳机佩戴于左耳时，其上的按键可以用于切换播放曲目，当耳机佩戴于右耳时，其上的按键可以用于调节音量。在这样的情况下，可以根据耳机当前的佩戴位置指示设置耳机的按键功能，从而提高用户的使用体验。
如图7所示，图7是本申请所提供的检测方法另一实施例的流程示意图，在一些实施例中，在S200之后，该检测方法进一步包括：
S400：发出提醒消息，提醒消息用于向用户提醒佩戴位置指示表征的佩戴位置，根据接收到用户的预设触发动作确定是否根据佩戴位置指示为耳机适配对应声道的音频信号，和/或，根据接收到用户的预设触发动作确定是否根据佩戴位置指示设置耳机的按键功能。
举例而言，提醒消息可以是与语音的形式发出的，用于向用户播报当前佩戴位置指示表征的佩戴位置。在一些实施例中，用户在接收到提醒消息时，可以自主判断佩戴位置指示所表征的佩戴位置是否准确，若准确，则可以在耳机上执行预设触发动作，比如，传递机械信号的动作、传递光信号的动作，或者传递电信号的动作，以使耳机根据佩戴位置指示表征的佩戴位置为耳机适配对应声道的音频信号和/或根据佩戴位置指示表征的佩戴位置设置耳机的按键功能。
在一些实施例中，用户可以自主判断佩戴位置指示所表征的佩戴位置是否准确，若不准确，则可以在耳机上执行预设触发动作，以使耳机不执行根据佩戴位置指示表征的佩戴位置为耳机适配对应声道的音频信号和/或不执行根据佩戴位置指示表征的佩戴位置设置耳机的按键功能的步骤，本申请对此不作限制，本领域技术人员可以根据实际需求进行选择。
本实施例的方案中，为用户提供了自主判断佩戴位置指示所表征的佩戴位置是否准确的机会，如此一来，即使当前的佩戴位置指示出现错误，也会被用户及时的识别出来，避免影响用户的使用体验。
在一些实施例中，耳机的数量为成对设置的两个，该检测方法进一步包括：
S500：响应于两个耳机当前的佩戴位置指示表征两个耳机佩戴于同一侧耳朵且持续预定时间，产生重置提醒。
举例而言，若用户将两个耳机分别佩戴在左耳和右耳上，在这种情况下，若两个耳机当前的佩戴位置指示均表征佩戴于左耳，则说明其中至少一个佩戴位置指示是错误的，此时，可以产生重置提醒，以在佩戴位置指示表征的佩戴位置出现错误时及时识别出来，避免影响用户的使用体验。
在一些实施例中，耳机的数量为成对设置的两个，该检测方法进一步包括：
S600：响应于两个耳机当前的佩戴位置指示表征两个耳机佩戴于同一侧耳朵，且其中一个耳机当前的佩戴位置指示的产生时间早于另一个耳机，保持所述其中一个耳机的佩戴位置指示不变，并重置所述另一个耳机的佩戴位置指示。
举例而言，若两个耳机当前的佩戴位置指示均表征佩戴于左耳，其中一个耳机当前的佩戴位置指示的产生时间早于另一个耳机，也就是说，其中一个耳机当前的佩戴位置指示是在先产生的，另一个耳机当前的佩戴位置指示是在后产生的，此时，对于佩戴位置指示在先产生的耳机，可以将其佩戴位置指示继续保持为左耳，对于佩戴位置指示在后产生的耳机，可以将其佩戴位置指示重置为右耳。随后，可以进一步根据两个耳机各自的佩戴位置指示适配对应声道的音频信号，和/或，根据两个耳机各自的佩戴位置指示适配按键功能。如此一来，在用户将两个耳机分别佩戴在左耳和右耳上时，有利于避免出现两个耳机播放同一声道的音频的情况，从而提高用户的使用体验。
在一些实施例中，该检测方法还包括：
S700：响应于耳机放入耳机盒的相应耳机仓，由耳机盒对佩戴位置指示进行重置。
耳机盒中可以设置有左耳机仓和右耳机仓。当耳机被放入耳机盒内时，耳机盒可以将放置于左耳机仓内的耳机的佩戴位置指示重置为左耳，将放置于右耳机仓内的耳机的佩戴位置指示重置为右耳。当用户再次从耳机盒中取出耳机时，习惯性的将左耳机仓内的耳机佩戴于左耳，将右耳机仓内的耳机佩戴于右耳，如此一来，进入佩戴状态之后，两个耳机的佩戴位置指示均能够正确的表征耳机的佩戴位置，从而能够迅速地为耳机配置对应声道的音频信号和按键功能，有利于提高用户的使用体验。
