一种耳机及一种实现佩戴检测和触控操作的方法 技术领域
本申请涉及耳机领域，尤其涉及一种耳机及一种实现佩戴检测和触控操作的方法。
背景技术
具有佩戴检测功能的耳机能够自动识别用户是否佩戴耳机，当耳机被摘下时，它能自动进入低功耗模式，当耳机被佩戴时，它能迅速从“睡眠”中苏醒，快速响应用户操作。因此，佩戴检测功能不仅能够简化用户操作，提升用户体验，而且是一项重要的节能措施，特别是对于依靠电池供电的无线耳机，能显著提高其续航能力。
常见的佩戴检测一般采用光学方案、电容检测方案或者是红外传感器方案，其中，光学方案和红外传感器方案存在结构设计复杂、成本高昂的问题；电容检测方案结构简单、无需开孔且成本低廉。但是这些方案都容易出现误触问题，当把耳机放置在桌面或者是手拿耳机时，容易被误判为已佩戴状态。
发明内容

与现有技术相比，本申请实施例的有益效果在于：本申请实施例提供了一种耳机及一种实现佩戴检测和触控操作的方法，解决了因误触而导致的佩戴检测的误判问题，当把耳机放置在桌面或者是手拿耳机时，能够避免被误判为已佩戴状态，显著地提高了佩戴检测的正确率。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请的部分实施例采用举例的方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在各例子中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。
请参考图1，是本申请实施例的耳机的第一结构图，本实施例基于图1中的耳机模型为例进行说明，但本领域的技术人员应当明了的是，此耳机模型仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择其他的模型实施本方案。图1中，耳机分为头部3和杆部6，但本领域的技术人员应当明了的是，在实际使用中，本领域的技术人员也可以选择没有杆部的耳机来实施本方案。另外，本实施例选择一只耳机为例进行说明，但本领域的技术人员应当明了的是，一只耳机仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择一副耳机实施本方案；需要注意的是，多个耳机的佩戴检测或者触控操作可以互相独立，也可以不相互独立，本实施例对此不做限制。另外，本实施例选择完全无线缆的真无线耳机为例进行说明，但本领域的技术人员应当明了的是，完全无线缆的真无线耳机仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择其他类型的耳机实施本方案，包括但不限于有线耳机和两耳机间带有线缆的无线耳机。
该耳机至少包括两个佩戴传感器，如图1，本实施例中，该耳机以包括两个佩戴传感器的耳机为例进行说明，但本领域的技术人员应当明了的是，包括两个佩戴传感器的耳机仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择包括两个以上佩戴传感器的耳机实施本方案。每一个佩戴传感器至少包括一个电容感应器，图1中，佩戴传感器1包括一个电容感应器，佩戴传感器2包括三个电容感应器，分别为电容感应器21、电容感应器22和电容感应器23。本实施例中的佩戴传感器分别包括一个和三个电 容感应器，但本领域的技术人员应当明了的是，佩戴传感器分别包括一个和三个电容感应器仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择佩戴传感器包括任意个数的电容感应器的情况实施本方案；本申请实施例中的佩戴传感器2的电容感应器21、电容感应器22和电容感应器23位置相邻，本实施例选择三个电容感应器相邻的佩戴传感器为例进行说明，但本领域的技术人员应当明了的是，佩戴传感器的电容感应器相邻的情况仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择电容感应器不相邻的佩戴传感器实施本方案。
本申请实施例中，如图1，佩戴传感器1的电容感应器21、电容感应器22和电容感应器23均为四边形，但本领域的技术人员应当明了的是，电容感应器的形状有多种，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择不同形状大小的电容感应器实施本方案，例如三角形和五边形等规则的形状和其他不规则形状。
本申请实施例中，两个佩戴传感器均设置在耳机头部与耳内皮肤组织有直接接触的不同位置。如图1，佩戴传感器1设置在喇叭口附近，佩戴传感器2设置在耳机头部底部，本实施例中的佩戴传感器分别设置在喇叭口附近和耳机头部底部，但本领域的技术人员应当明了的是，佩戴传感器设置喇叭口附近和耳机头部底部仅为示例性说明，在实际使用中，本领域的技术人员可以参照本申请实施例的方案，选择将佩戴传感器设置在其他不同的位置来实施本方案。在用户佩戴耳机时，若耳朵的皮肤组织与佩戴传感器接触，则会引起佩戴传感器的电容感应器上电容值的变化，从而可以根据佩戴传感器上的电容值来实现佩戴检测的功能。一方面，用手拿耳机时，若接触到佩戴传感器也会引起其上电容值的变化，另一方面，桌子接触到佩戴传感器也会引起电容感应器上电容值的变化。因此如果仅仅以一个佩戴传感器上检测到的电容值作为佩戴检测的依据，则耳机则容易因误触问题被误判为已佩戴状态。在本申请实施例中，以所有佩戴传感器检测到的电容值作为检测耳机处于已佩戴状态的基础，同时由于佩戴传感器1和佩戴传感器2设置在不同的位置，一般不会同时接触到佩戴传感器1 和佩戴传感器2，经过如此配置后的耳机，能够从很大程度上减小因误触而导致误判的情况，显著地提高了佩戴检测的正确率。
在本申请实施例中，以任一佩戴传感器上的电容感应器检测到的最大电容值或者电容值之和作为各个佩戴传感器的最大检测值，当所有的佩戴传感器的最大检测值不小于佩戴阈值时，才判断耳机为已佩戴状态。需要说明的是，对于不同的佩戴传感器，佩戴阈值可以相同，也可以不同。另外，需要说明的是任一佩戴传感器上的电容感应器检测到的电容值之和可以为任一佩戴传感器上的部分或者全部电容感应器检测到的电容值之和，在此不做限制。
可选的，在一个实施例中，如图1所示，佩戴传感器1的电容感应器上检测到的电容值作为佩戴传感器1的最大检测值，对于佩戴传感器2的最大检测值，佩戴传感器2的三个电容感应器上检测到的电容值之和可以作为佩戴传感器2的最大检测值，佩戴传感器2的三个电容感应器上检测到的最大电容值也可以作为佩戴传感器2的最大检测值。当佩戴传感器1和2的最大检测值分别不小于佩戴传感器1和2的佩戴阈值时，判断耳机为已佩戴状态，需要说明的是，可以为佩戴传感器1和2设置相同的佩戴阈值，也可以设置不同的佩戴阈值，本申请实施例对此不做限定。
耳机的佩戴位置会直接影响用户体验，佩戴位置不正确不仅会带来易脱落的问题，更容易影响音质体验。为了指导用户正确佩戴，需要检测用户的佩戴位置是否正确。佩戴传感器包括至少一个第一佩戴传感器，第一佩戴传感器包括至少两个电容感应器；任意一个第一佩戴传感器的任一电容感应器上检测到的电容值小于正确佩戴阈值时，判断耳机未正确佩戴。需要注意的是，只有当处于已佩戴状态时，才去检测耳机是否正确佩戴。在本申请实施例中，选择包括三个电容感应器的佩戴传感器作为第一佩戴传感器，用以检测耳机是否正确佩戴。具体的，当所有的第一佩戴传感器中所有电容感应器检测的电容值均大于或者等于正确佩戴阈值时，才可判定该耳机处于正确佩戴状态。如图1中，佩戴传感器2包括三个电容感应器，分别为电容感应器21、电容感应器22和电容感应器23，则佩戴传感器2可以作为第一 佩戴传感器。本实施例中的第一佩戴传感器包括三个电容感应器，但本领域的技术人员应当明了的是，第一佩戴传感器包括三个电容感应器仅为示例性说明，第一佩戴传感器可以包括两个或两个以上的电容感应器；在本申请实施例中，当耳机处于已佩戴状态时，若电容感应器21、电容感应器22和电容感应器23上检测到的任意一个电容值小于电容感应器21、电容感应器22和电容感应器23对应的正确佩戴阈值，判断耳机未正确佩戴。需要注意的是，耳机处于已佩戴状态时，电容感应器处在不同的位置，与皮肤接触的情况不同，电容感应器的电容值也就不同，因此电容感应器21、电容感应器22和电容感应器23对应的正确佩戴阈值可以相同，也可以不同，本实施例对此不做限制。本实施例中的第一佩戴传感器只有一个，但本领域的技术人员应当明了的是，该耳机包括一个第一佩戴传感器仅为示例性说明，该耳机还可以包括多个第一佩戴传感器。在本实施例中，由于只存在一个第一佩戴传感器，所以只需要在已佩戴状态下判断这个第一佩戴传感器是否满足正确佩戴的条件，如果存在多个第一佩戴传感器，则需要判断每一个第一佩戴传感器是否满足正确佩戴的条件，若都满足，则为正确佩戴。
在本实施例中，以佩戴传感器2的三种不同位置表示耳机的三种佩戴情况，如图2所示，佩戴传感器2包括三个电容感应器21、22和23，图2(a)描述了耳机正确佩戴时，佩戴传感器2所在的位置，在这个佩戴位置，耳机不易脱落且用户的音质体验较好，由图可知，电容感应器21与对耳屏52接触，电容感应器23与耳屏53接触，电容感应器22处于屏间切迹51上方，电容感应器22基本与耳朵无接触，由于电容感应器与耳朵接触时，电容值会变大，所以电容感应器23和21的电容值较大，电容感应器22的电容值较小。如图2(b)所示，电容感应器23和22与耳屏53接触接触，电容感应器21处于屏间切迹51上方，电容感应器21与耳朵基本无接触，此时电容感应器23和22的电容值较大，电容感应器21的电容值较小。如图2(c)所示，电容感应器22和21与对耳屏52接触，接触，电容感应器23处于屏间切迹51上方，电容感应器23与耳朵基本无接触，此时电容 感应器22和21的电容值较大，电容感应器23的电容值较小。对于佩戴传感器2的三个电容感应器都可以设置对应的正确佩戴阈值，以此判断耳机是否处于正确的佩戴位置，在本实施例中，可以给电容感应器23和21设置较大的正确佩戴阈值，而给电容感应器22设置较小的正确佩戴阈值，需要说明的是，本实施例中这种设置正确佩戴阈值的方案仅为示例性说明，本领域的技术人员可以根据不同的使用需求，用不同的方案给佩戴传感器的电容感应器设置正确佩戴阈值。
优选的，当耳机未正确佩戴时，还可以提示用户调整佩戴位置，例如，在图2(a)的情况下，电容感应器23和21电容值较大，电容感应器22的电容值较小，属于正确佩戴状态，可以不设置提示；在图2(b)的情况下，电容感应器23和22的电容值较大，电容感应器21的电容值较小，则可以提示用户逆时针旋转耳机，使电容感应器21的电容值增大、电容感应器22的电容值减小，回到正确佩戴的状态；在图2(c)的情况下，电容感应器22和21的电容值较大，电容感应器23的电容值较小，可以提示用户顺时针旋转耳机，使电容感应器23的电容值增大、电容感应器22的电容值减小，回到正确佩戴的状态，另外，也可以根据检测到电容值与正确佩戴阈值的差值去提示用户调整佩戴位置时顺时针或者逆时针旋转的角度。
可选的，佩戴传感器的电容感应器可以直接设置在耳机外壳内表面，也可以通过注塑工艺或者其他工艺设置在耳机外壳内部。
如图3，是本申请实施例的耳机的第二结构图，可选的，耳机还包括触控传感器和检测处理电路，耳机的检测处理电路用于检测和处理佩戴传感器与触控传感器的电容值，佩戴传感器与触控传感器和检测处理电路连接，佩戴传感器与触控传感器共用检测处理电路，不需要增加额外硬件电路就可以同时实现触控和佩戴检测，能够很大程度的降低成本，另一方面，降低了集成难度。触控传感器设置在耳机头部或耳机杆部远离耳朵的位置，用于耳机处于已佩戴状态下时检测触控操作，触控传感器的触发方式包括但不限于触摸或者触摸时滑动。
可选的，检测处理电路包括驱动器；如图3，触控传感器包括电容感应器；由于触控传感器和佩戴传感器都包括电容感应器，所以可 以共用驱动电路，驱动器与佩戴传感器和触控传感器的全部电容感应器连接，用于驱动佩戴传感器和触控传感器的全部电容感应器。
可选的，检测处理电路包括多路复用器；多路复用器与佩戴传感器和触控传感器连接，用于对佩戴传感器和触控传感器的全部电容感应器采集的电容信号进行信号选择。如图3，检测处理电路还包括电容检测电路、模数转换器和处理器，如果没有多路复用器，每一个电容感应器也可以单独对应一组电容检测电路和模数转换器，但是这种方式会使得成本增加，也不便于集成。
可选的，触控传感器的全部电容感应器设置在耳机外壳内表面或外壳内部。与佩戴传感器相同，触控传感器的电容感应器可以直接设置在耳机外壳内表面，也可以通过注塑工艺或者其他工艺设置在耳机外壳内部，如图4，图4(a)中，触控传感器4的电容感应器41、42、43可以直接设置在耳机杆部外壳内表面62，图4(b)中，触控传感器的电容感应器设置在耳机杆部外壳内部，即耳机杆部外壳内表面62与耳机杆部外壳外表面61之间。另外，本实施例以四边形的电容感应器为例，但是对触控传感器的电容感应器的形状和大小不做限制。另外，本实施例以杆部的电容感应器为例，但是不限制电容感应器的位置，触控传感器的电容感应器还可以设置在耳机头部，
可选的，检测处理电路包括主控芯片；在已佩戴状态下和未佩戴状态下时，主控芯片可以预设频率更新当前的佩戴状态，这样可以随时监控用户的佩戴动作，在已佩戴状态下和未佩戴状态下更新当前佩戴状态的预设频率可以不同。
本申请实施例提供了一种耳机，解决了因误触而导致的佩戴检测的误判问题，当把耳机放置在桌面或者是手拿耳机时，能够避免被误判为已佩戴状态，显著地提高了佩戴检测的正确率。
本实施例还提供一种实现佩戴检测和触控操作的方法，该方法应用于该耳机，如图5所示，该方法包括：
步骤51：采集全部佩戴传感器的电容值；
步骤52：判断每一个佩戴传感器的最大检测值是否都不小于佩戴阈值；
步骤53：如果是，则判断耳机为已佩戴状态，并设置触控传感器处于工作状态。
以多个不同位置的佩戴传感器的电容传感器的值为依据判断是否佩戴，能在很大程度上减少因误触带来的误判问题，提高了佩戴检测的正确率。佩戴状态为已佩戴状态时，设置触控传感器处于工作状态，只有当耳机处于已佩戴状态时，才响应用户的触控操作，当耳机被摘下时，它能自动进入低功耗模式，对用户的触控操作不响应。当耳机被佩戴时，它能迅速从“睡眠”中苏醒，快速响应用户操作，能够达到节能的目的，特别是对于依靠电池供电的无线耳机，能显著提高其续航能力。
可选的，如果耳机处于已佩戴状态，可以执行以下步骤：
步骤54：判断任意一个第一佩戴传感器的全部电容感应器上检测到的任一电容值是否小于正确佩戴阈值；
步骤55：如果是，判断耳机未正确佩戴，并设置调整佩戴位置的提示。
为了指导用户正确佩戴，需要检测用户的佩戴位置是否正确。需要注意的是，只有当处于已佩戴状态时，才去检测耳机是否正确佩戴。耳机处于已佩戴状态时，电容感应器处在不同的位置，与皮肤接触的情况不同，电容感应器的电容值也就不同，因此，可以根据电容感应器的电容值判断耳机是否正确佩戴，当第一佩戴传感器的每个电容感应器上的电容值不小于该电容感应器对应的正确佩戴阈值时，该第一佩戴传感器处于耳机正确佩戴时它所对应的位置，需要所有的第一佩戴传感器都满足该条件才能判断耳机处于正确佩戴状态；当耳机未正确佩戴时，可以根据第一佩戴传感器的电容感应器的电容值设置调整耳机佩戴位置的提示，用户根据该提示可以调整耳机佩戴位置，如何根据电容感应器的电容值设置调整耳机佩戴位置的提示在前面已经举例说明，此处不再赘述。
另外，还需要以预设频率更新耳机的当前佩戴状态，以便能对用户取下或者戴上耳机的动作及时检测并作出响应，需要注意的是，在已佩戴状态下，需要以预设频率更新当前耳机的佩戴状态，在未佩戴 状态，也可以以预设频率更新当前耳机的佩戴状态，这两种情况的预设频率可以不同，也可以相同，本实施例对此不做限制。
可选的，利用佩戴传感器可以实现计步检测的功能，在运动过程中，佩戴传感器的电容感应器与皮肤的接触情况会有所变化，因此佩戴传感器的最大检测值会发生抖动，当抖动量不小于计步抖动阈值时，执行步数增加的操作，以更新当前计步数据，需要说明的是，当抖动量不小于计步抖动阈值时，步数可以加1也可以加2，可以根据抖动量的幅度来确定步数增加的多少，本实施例对此不做限制。
本申请实施例提供了一种实现佩戴检测和触控操作的方法，该方法应用于该耳机，解决了因误触而导致的佩戴检测的误判问题，当把耳机放置在桌面或者是手拿耳机时，能够避免被误判为已佩戴状态，显著地提高了佩戴检测的正确率。
