具体实施方式
下面将详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图1-图5，通过具体的实施例及其应用场景对本申请实施例提供的耳机状态检测方法、检测装置、耳机以及可读储存介质进行详细地说明。
在本申请的一些实施例中，提供了一种耳机状态检测方法，该耳机状态检测方法应用于耳机。如图1所示，所述耳机包括壳体14以及位于所述壳体14内的主板13、第一电容传感器11和第二电容传感器12。
所述主板13分别与所述第一电容传感器11和所述第二电容传感器12电连接，所述主板13上设置有接地区2；所述第一电容传感器11位于所述壳体14与所述第二电容传感器12之间；所述第二电容传感器12位于所述第一电容传感器11与所述主板13之间。
如图2所示，所述方法包括：
S2100：获取所述第一电容传感器11输出的第一电容值和所述第二电容 传感器12输出的第二电容值。
在本申请中，第一电容传感器11位于第二电容传感器12与壳体14之间，第一电容传感器11感测壳体14一侧的电容值，第二电容传感器12感测主板13一侧的电容值。其中，第一电容传感器11的电容值不会受到主板13一侧的影响，第二电容传感器12的电容值不会受到壳体14一侧的影响。
该耳机处于佩戴状态下的条件能够对第一电容传感器11和第二电容传感器12的电容值产生影响。通过获取第一电容传感器11的第一电容值和第二电容传感器12的第二电容值，能够判断耳机是否被佩戴。
S2200：在所述第一电容值和所述第二电容值满足预设条件的情况下，确定所述耳机处于佩戴状态。
第一电容值和第二电容值对应地反映了第一电容传感器11和第二电容传感器12受到的外部条件的影响。当第一电容值和第二电容值满足预设条件时，对耳机产生影响的外部条件即为耳机处于佩戴状态下的条件。
本申请通过获取第一电容传感器11输出的第一电容值和第二电容传感器12输出的第二电容值，能够更加精确地检测到耳机是否处于佩戴的状态。
在本申请的一些实施例中，提供了一种耳机状态检测方法，所述方法包括：
S2100：获取所述第一电容传感器11输出的第一电容值和所述第二电容传感器12输出的第二电容值；
S2200：在所述第一电容值和所述第二电容值满足预设条件的情况下，确定所述耳机处于佩戴状态。
其中，S2200:在所述第一电容值和所述第二电容值满足预设条件的情况下，确定所述耳机处于佩戴状态，包括：
S2210：在所述第一电容值大于第一阈值，所述第二电容值大于第二阈值，以及所述第一电容值与所述第二电容值的差值大于第三阈值的情况下，确定所述耳机处于佩戴状态。
其中，耳机处于佩戴状态时，壳体14与用户接触，用户向第一电容传感器11提供了一个接地的低电势，从而影响第一电容传感器11产生第一电容值。并且，第一电容传感器11在与用户接触时还受到用于接触以外的影响。主板13向第二电容传感器12提供接地，第二电容传感器12在主板13一侧受到影响产生第一电容值，第二电容传感器12受到的影响为用户接触以外的影响。根据第一电容值与第二电容值的差值，消除接触以外的影响，使差值仅反应接触造成的影响。当差值大于第三阈值时，确定第一电容传感器11仅因接触产生的电容值满足耳机与用于佩戴状态产生的接触条件。进一步结合第二电容值满足第二阈值的判断，这样能够更加精确地判断耳机是否处于佩戴的状态。
S2200：当所述第一电容值和所述第二电容值满足预设条件的情况下，确定所述耳机处于佩戴状态，还包括：
S2220：当所述第一电容值在第一时长内的第一变化值大于第四阈值，所述第二电容值在第二时长内的第二变化值大于第五阈值，以及所述第一变化值与所述第二变化值的差值大于第六阈值时，确定所述耳机处于佩戴状态。
获取第一电容值在第一时长内的第一变化值，并通过第一变化值与第一阈值作比较，能够避免接触在第一电容传感器11上产生的电容值对第一电容值的影响，使获取的第一变化值准确地反应了第一电容传感器11受到外部条件影响而产生的变化。同样地，第二电容值在第二时长内的第二变化值能够准确地反应第二电容传感器12受到外部条件影响而产生的变化。
通过第一变化值与第二变化值的差值与第六阈值比较，能够更加准确地消除接触造成的影响以外的外部条件对检测的影响，以进一步提高耳机佩戴状态检测的准确度。
该实施例中，在第一时长内获取第一变化值，能够获取第一电容传感11的更加准确的第一电容值，避免瞬间接触造成误触产生错误的判断。在第二时长内获取第二变化值，能够更准确地获取温度对电容值的影响。例如，在温度作用的情况下，耳机的温度会在一定时间内改变至与外部温度相同或相近。在第二时长内获取温度影响产生的第二变化值，提高了获取温度影响产生的电容值变化的精确度。
在本申请一个实施例中，如图3所示，耳机状态检测方法包括：
S3100：获取所述第一电容传感器11输出的第一电容值和所述第二电容传感器12输出的第二电容值。
S3200：当所述第一电容值小于或等于第一阈值，所述第二电容值小于或等于第二阈值，或者所述第一电容值与所述第二电容值之间的差值小于或等于第三阈值时，确定所述耳机处于未佩戴状态。
当满足该实施例中的任意一项时，耳机处于未佩戴状态，第一电容传感器11和第二电容传感器12所产生的电容值由佩戴以外的外部接触条件造成。
在上述耳机状态检测方法的实施例的基础上，S3200步骤还包括：
S3210：当第一电容值小于或等于第一阈值时，第一电容传感器11没有收到足够的影响，判断第一电容传感器11没有达到佩戴状态产生的接触状态。这种情况下，判断耳机处于未佩戴状态。
在上述耳机状态检测方法的实施例的基础上，S3200步骤还包括：
S3220：当所述第一电容值大于第一阈值，所述第二电容值小于或等于第 二阈值时，判断耳机为受到异物接触干扰。该异物干扰为其他物体接触耳机造成的，例如，汗液或水滴等液体。
当第一电容值大于第一阈值时，第一电容传感器11通过第一电容值反应了壳体14受到了接触的影响，满足了接触条件。通过第一电容值与第二阈值的比较，当第二电容值小于或等于第二阈值时，则判断第二电容传感器12没有受到足够的温度影响。这时的接触影响并不是用于耳部的接触。
当耳机处于佩戴状态时，耳机的温度会因为接触用户而升高，所以第二电容值也应当大于第二阈值。当第二电容值不大于第二阈值时，则判断第二电容传感器12没有受到足够的温度影响，所以判断耳机不是处于佩戴的状态。
在上述耳机状态检测方法的实施例的基础上，S3200步骤还包括：
S3230：当所述第一电容值大于第一阈值，所述第二电容值大于第二阈值，以及所述第一电容值与所述第二电容值的差值小于或等于第三阈值时，则判断耳机为受到温度干扰。
处于佩戴状态时，用户产生的温度会使耳机的温度逐渐升高，而外部异物产生的温度干扰会逐渐降低。
当所述第一电容值大于第一阈值，所述第二电容值大于第二阈值时，耳机满足了接触和温度的条件。通过第一电容值与第二电容值的差值与第三阈值比较，消除了温度对第一电容传感器11产生的第一电容值的影响，差值为仅受接触的影响所产生的电容值。当第一电容值与第二电容值的差值小于或等于第三阈值时，则仅受接触影响使第一电容传感器11产生的电容值不满足接触的条件。则判断耳机为受到温度干扰。
当耳机处于佩戴状态时，在耳机因用户佩戴升温的同时，仅由耳机与用户接触的条件产生的电容值也会满足条件，第一电容值与第二电容值的差值 应当大于第三阈值。当差值小于第三阈值时，说明耳机的状态不满足佩戴时仅由接触产生的电容值的条件。
例如，由于外界温度的干扰，使第一电容值大于第一阈值，且第二电容值大于第二阈值。第一电容值与第二电容值的差值消除了温度影响，因此差值小于或等于第三阈值时，反映了消除温度影响后的电容值不满足仅由接触产生的电容值的条件。
本申请的实施例通过获取第一电容传感器11输出的第一电容值和第二电容传感器12获取的第二电容值，能够更加精确地检测到耳机是否处于佩戴的状态。
在上述实施例的基础上，耳机状态检测方法还包括：
屏蔽所述第一电容传感器11的感应区域以外的电压信号和所述第二电容传感器12的感应区域以外的电压信号。
屏蔽感应区域以外的电压信号，这使得第一电容传感器11和第二电容传感器12只对感应区域内的影响产生反应。例如，当耳机处于佩戴状态下，用于接触的区域为感应区域。在感应区域以外的部位受到影响时，第一电容传感器11不受影响。这样能够进一步提高检测耳机佩戴状态的精确度。
需要说明的是，本申请实施例提供的耳机状态检测方法，执行主体可以为耳机状态检测装置，或者，或者该耳机状态检测装置中的用于执行加载耳机状态检测方法的控制模块。本申请实施例中以耳机状态检测装置执行加载耳机状态检测方法为例，说明本申请实施例提供的耳机状态检测方法。

在本申请的耳机结构中，所述壳体14上具有接触区，所述接触区用于与佩戴对象接触，所述第一电容传感器11与所述接触区相对。
在耳机被佩戴时，接触区与用户皮肤接触，从而改变第一电容传感器11的电容值。用户接触的位置与第一电容传感器11重合的区域面积越小则对电容值的影响越小，第一电容传感器11与接触区相对，能够使接触的位置与第一电容传感器11重合。这样用户接触到接触区的部分能够有效地对第一电容传感器11的电容值产生影响，从而保障了第一电容传感器11的灵敏度。
例如，所述第一电容传感器11和所述第二电容传感器12均为平行板电容传感器。
平行板电容传感器设置在壳体14内，外界与壳体14接触的对象能够形成接地导电平面，该导电平面平行于第一电容传感器11，从而形成平行板电容。形成的平行板电容器的电容值即为第一电容值。平行板电容传感器能够提高检测灵敏度。

传感器芯片4能够通过主板13的电路与第一电容传感器11和第二电容传感器12形成电连接，从而检测第一电容传感器11和第二电容传感器12的电容值。通过计算和比较第一电容值和第二电容值，判断出耳机是否被用户佩戴或者有液体落在耳机上形成了干扰。
可选地，所述主板13通过柔性线路板5与所述第一电容传感器11和所述第二电容传感器12电连接。
通过柔性线路板5更容易在耳机内走线。这样走线使第一电容传感器11和第二电容传感器12更容易与主板13形成电连接。降低了走线难度。
可选地，所述第二电容传感器12与所述接地区2相对。
接地区2向第二电容传感器12提供了接地端，接地区2与第二电容传感器12之间的距离不会发生变化，使第二电容传感器12与接地区2形成稳定的电场。保障了接地区2与第二电容传感器12形成电容的稳定性。
例如，所述主板13上设置有多个所述接地区2。
多个接地区2增加了接地区域的面积，使第二电容传感器12能够形成稳定的电容。
可选地，所述容纳腔内还设置有第一屏蔽电容板6，所述第一屏蔽电容板6围绕所述第一电容传感器11设置，第一屏蔽电容板6与主板13电连接。
第一屏蔽电容板6为电容。通过第一屏蔽电容板6在第一电容传感器11的周围形成同向相位的驱动信号，使第一电容传感器11周围的壳体14上保持等势的电压，从而避免与第一电容传感器11相对的接触区以外的区域与接触对象接触对第一电容传感器11的电容值产生影响。
可选地，所述容纳腔内还设置有第二屏蔽电容板7，所述第二屏蔽电容 板7围绕所述第二电容传感器12设置，第二屏蔽电容板7与主板13电连接。
第二屏蔽电容板7与第一屏蔽电容板6的工作原理相同，避免第二电容传感器12范围外的物体对第二电容传感器12的电容值产生影响。
本申请通过获取第一电容传感器11输出的第一电容值和第二电容传感器12获取的第二电容值，并通过上述方法计算比较。避免了外部影响因素对检测准确性的影响，能够更加精确地检测到耳机是否处于佩戴的状态。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器， 空调器，或者网络设备等)执行本申请各个实施例所述的方法。
上面结合附图对本申请的实施例进行了描述，但是本申请并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本申请的启示下，在不脱离本申请宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本申请的保护之内。
