具体实施方式
下面将结合附图，对本申请各个实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请的一部分实施例， 而不是全部的实施例。基于本申请中的实施例，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他实施例，都属于本申请保护的范围。
图1是根据本申请一个实施例提供的具有耳机插孔的音频输出装置的结构示意图。
如图1所示，音频输出装置包括耳机插孔5、片上系统(SoC)电路1、电源电路2、音频数字信号处理/放大电路3和扬声器电路4。
音频输出装置对耳机插孔5是否有耳机的插入或拔出进行检测。当将耳机插入到耳机插孔5中时，SoC电路可接收到来自耳机插孔5的指示耳机插入的检测信号(如，耳机/扬声器控制信号的电平为高)，并将音频信号输出到耳机插孔5，同时停止扬声器电路4输出音频信号。当将耳机从耳机插孔5中拔出时，SoC电路可接收到来自耳机插孔5的指示耳机拔出的检测信号(比如，耳机/扬声器控制信号的电平为低)，SoC电路1将音频信号通过音频数字信号处理/放大电路3输出到扬声器电路4，同时停止通过耳机插孔5输出音频信号。
用户每次在传统的音频输出装置上使用耳机时都需要进行插入操作，不需要耳机时都需要进行拔出操作，操作便利性较低。而且，随着薄型电子设备的普及，音频输出设备的耳机插孔变得越来越小，耳机和耳机插孔之间的结合更紧密，使得目前的耳机越来越不容易插入耳机插孔中，进一步降低操作便利性。
本申请实施例提供一种解决上述技术问题的技术方案。
如图2所示为根据本申请的耳机控制电路的示意性框图，耳机控制电路包括：
检测模块21，设置在耳机的耳壳或耳壳附近的线材上，用于检测耳机的佩戴状态，并且输出用于指示耳机佩戴状态的检测信号；
判断模块22，用于根据来自检测模块21的检测信号，判断所述耳机当前是否处于佩戴状态，输出用于指示所述耳机处于佩戴状态或非佩戴状态的控制信号。在本申请实施例中，假设当判断耳机处于佩戴状态时，输出第一控制信号；当判断耳机处于非佩戴状态时，输出第二控制信号。SoC电路可接收第一控制信号和第二控制信号，根据第一控制信号和第二控制信号控制通过耳机或扬声器输出音频信号。
在一些实施方式中，检测模块21包括一个或多个传感器，每一个 传感器用于检测与耳机的佩戴状态相关的数据。当需要检测耳机佩戴状态时，至少启动其中一个传感器，通过该传感器检测的数据，可以确定耳机是否处于佩戴状态。具体地，所述传感器可以是三轴加速度传感器，可替换地，也可以是温度传感器、压力传感器等。
上述实施例中，当检测模块21包括三轴加速度传感器时，三轴加速度传感器可以采用压阻式、压电式和电容式等形式。三轴加速度传感器产生的加速度可分别与电阻、电压和电容的变化成比例，并且通过相应的放大和滤波电路进行采集。加速度是个空间矢量，利用三轴加速度传感器一方面可以测得三个坐标轴上的分量，以准确了解耳机的运动状态；另一方面，只有应用三轴加速度传感器来检测加速度信号才可以在预先不知道耳机运动方向的场合下进行检测。三轴加速度传感器通过检测XYZ三个坐标轴上的分量，可以准确地感测到耳机随着使用者的头部的运动，因此可以得到与耳机的佩戴状态相关的数据。三轴加速度传感器具有体积小和重量轻的特点，可以测量空间加速度，能够全面准确地反映物体的运动性质。
比如，当三轴加速度传感器检测到耳机运动时或一段时间内连续发生运动时，可确定耳机处于佩戴状态，当耳机处于静止状态时候或在一定时间段内处于静止状态时，可确定耳机处于非佩戴状态。在一些实施方式中，还可以采用温度传感器检测耳机的佩戴状态。例如，当耳机处于佩戴状态时，耳壳靠近人脸或耳壳插入耳道中；当处于非佩戴状态时，远离人脸不与人体接触。其中一种实施方式为：通过耳壳上的温度传感器可以感测耳机周边的温度，当温度接近人脸温度时确定耳机处于佩戴状态，否则，处于非佩戴状态。也可以将温度传感器设置在可以与耳道或人脸相接触的位置，使得检测结果更加准确。
在另一些实施方式中，还可以采用压力传感器检测耳机的佩戴状态。比如，对于头戴式耳机而言，在佩戴时耳壳需要一定的压力以使其保持在使用者的头部，因此可以通过耳壳上设置的压力传感器来感测与耳机的佩戴状态相关的数据。
当然，检测模块21可以同时配置有不同类型的传感器，且配置开关装置，在某时刻启动某一个传感器来检测耳机是否处于佩戴状态。为了避免误操作可以同时启动两个或两个以上的传感器来综合确定耳机的佩戴状态。
参见图2，判断模块22可以包括AD转换器221，用于将从所述检测模块21接收的检测信号转换为数字信号。判断模块22还可以包括控制信号输出单元222，用于根据所述检测信号输出指示所述耳机处于佩戴状态或非佩戴状态的控制信号。
以检测模块21包括三轴加速度传感器为例，判断模块22可以通过AD转换器221将来自三轴加速度传感器的XYZ三个坐标轴上的分量转换成数字信号，将转换后的数字信号与对应于运动状态的预设数据进行比较，当比较的结果相匹配时，表明三轴加速度传感器感测的数据指示了耳机处于佩戴状态时，控制信号输出单元222可以输出指示该耳机处于佩戴状态的控制信号，当比较的结果不相匹配时，表明三轴加速度传感器感测的数据指示了耳机处于非佩戴状态时，控制信号输出单元222可以输出指示该耳机处于非佩戴状态的控制信号。耳机控制电路还可以包括开关模块23，用于开启/关闭耳机控制电路。当开启耳机控制电路时，判断模块22输出指示所述耳机是否处于佩戴状态的控制信号。当关闭耳机控制电路时，判断模块22始终输出指示所述耳机处于佩戴状态的控制信号。当用户在躺着时佩戴耳机，检测模块21可能检测不出耳机是否处于佩戴状态，这时将耳机控制电路中的开关模块23设置成关闭的状态，就可以将根据本申请的耳机用作普通的耳机。
根据本申请的耳机，通过对耳机的实际佩戴状态进行检测，并且在耳机处于佩戴状态的情况下发出控制信号，通知与该耳机相连接的音频输出装置通过该耳机输出音频信号。此外，在耳机未处于佩戴状态的情况下，仍旧通过音频输出装置的扬声器输出音频信号，而无需从音频输出装置上拔出耳机。根据本申请的耳机与现有技术的区别在于，将通过判断耳机的插拔操作来切换输出方式改变为通过判断耳机的实际佩戴状态来切换输出方式，进而避免了耳机的反复插拔操作。
图3是根据本申请的耳机的示意图。耳机可以包括输入模块，用于接收从音频输出装置输入的信号；输出模块，用于输出音频信号；以及根据本申请的耳机控制电路。
作为输入模块，耳机可以包括插入音频输出装置的耳机插孔的耳机插头，其可以从音频输出装置接收左右声道的音频信号(Left信号和Right信号)、GND信号以及电源信号(VCC)。此外，耳机插头还可 以向音频输出装置传输由耳机控制电路的判断模块的控制信号输出单元输出的控制信号(Control信号)，如第一控制信号和第二控制信号。
如图3所示，耳机控制电路的检测模块可以包括三轴加速度传感器(3轴加速度传感器)。判断模块可以包括AD转换器。开关模块可以包括电源开关和电源LED，当电源开关开启耳机控制电路时，电源LED点亮，判断模块输出指示所述耳机是否处于佩戴状态的控制信号。当电源开关关闭耳机控制电路时，电源LED熄灭，判断模块始终输出指示所述耳机处于佩戴状态的控制信号。
现有技术中主流的耳机插头是3极类型，如图4中的耳机a所示，其中第①触点(附图中的标识1)连接左声道音频信号，第②触点(附图中的标识2)连接右声道音频信号，第③触点(附图中的标识3)连接GND信号。耳机插头还可以是带MIC的4极类型，如图4中的耳机b所示。4极类型的耳机插头可以分为两种，一种是CTIA(Cellular Telephone Industry Association)，其中第①触点连接左声道音频信号，第②触点连接右声道音频信号，第③触点连接GND信号，第④触点(附图中的标识4)连接MIC；另一种是OMTP(Open Mobile Terminal Platform)，其中第①触点连接左声道音频信号，第②触点连接右声道音频信号，第③触点连接MIC，第④触点连接GND信号。
由于需要输出表示耳机的佩戴状态的控制信号，因此根据本申请的耳机的耳机插头可以是5极类型，如图4所示的耳机c，每一个触点对应5极类型中的一个极类型。其中第①触点连接左声道音频信号(Left信号)，第②触点连接右声道音频信号(Right信号)，第③触点连接GND信号，第④触点输出控制信号(Control信号)，第⑤触点(附图中的标识5)连接电源信号(Vcc)。上述3极、4极、5极类型的耳机插头的布线如表1所示。
表1：3极、4极、5极类型的耳机插头的布线
Figure PCTCN2016101864-appb-000001
由表1可以看出，根据本申请的耳机可以兼容现有技术中的3极类型和4极CTIA类型的耳机插头，但是当使用现有技术中的这些耳机插头时，不能输出指示耳机的佩戴状态的控制信号，因此其只能用作普通的耳机。
根据本申请实施例提供的耳机可以是如图5中的头戴式耳机a；还可以是如图5中的耳塞式耳机b。
图6是根据本申请的音频输出装置的示意图。根据本申请的音频输出装置包括5极型耳机插孔、片上系统、电源、音频数字信号处理/放大电路、扬声器和开关电路。
如图6所示，根据本申请的音频输出装置包括与耳机插头对应的耳机插孔65、片上系统(SoC)电路61、电源电路62、音频数字信号处理/放大电路63、扬声器电路64和开关电路66。音频输出装置不仅对耳机插孔65是否有耳机的插拔进行检测，还接收来自耳机的控制信号。当将根据本申请的耳机插入到耳机插孔65中时，音频输出装置接收来自耳机的控制信号，并且根据指示耳机是否处于佩戴状态的控制信号生成耳机/扬声器控制信号。当来自耳机的控制信号指示耳机处于佩戴状态时，开关电路66导通，生成的耳机/扬声器控制信号指示通过耳机输出音频信号，音频输出装置的片上系统(SoC)电路61将音频信号输出到耳机插孔65，而停止扬声器电路64输出音频信号。当来自耳机的控制信号指示耳机未处于佩戴状态时，开关电路截止，生成的耳机/扬声器控制信号指示通过扬声器输出音频信号，音频输出装置的片上系统(SoC)电路61将音频信号通过音频数字信号处理/放大电路63输出到扬声器电路64，而停止通过耳机插孔65输出音频信号。
根据本申请的耳机，通过对耳机的实际佩戴状态进行检测，并且在耳机处于佩戴状态的情况下发出控制信号，通知与该耳机相连接的音频输出装置通过该耳机输出音频信号。此外，在耳机未处于佩戴状态的情况下，仍旧通过音频输出装置的扬声器输出音频信号，而无需从音频输出装置上拔出耳机。根据本申请的音频输出装置通过判断耳机的插拔操作来切换输出方式改变为通过指示耳机的实际佩戴状态的控制信号来切换输出方式，进而避免了耳机的反复插拔操作，从而解决了薄型电子设备不容易插入耳机的问题，提高了用户操作的便利性。
此外，当音频输出装置的片上系统(SoC)电路61输出静音(Mute)信号时，将停止从耳机和扬声器输出音频信号。
图7是根据本申请的耳机控制方法的流程图。如图7所示，耳机控制方法包括：步骤701，检测耳机是否处于佩戴状态，具体的检测耳机处于佩戴状态还是非佩戴状态；步骤702，输出用于指示所述耳机处于佩戴状态或非佩戴状态的检测信号；步骤703，根据所述检测信号确定所述耳机是否处于佩戴状态；以及步骤704，输出用于指示所述耳机是否处于佩戴状态的控制信号。
在步骤701中，可以通过传感器来检测与耳机的佩戴状态相关的数据，传感器和检测方式已经在上文中描述，这里仅是简单说明。传感器可以包括三轴加速度传感器。可替换地，传感器还可以包括温度传感器、压力传感器等。在步骤702中，传感器输出指示与耳机的佩戴状态相关的数据。在步骤703中，根据来自传感器的数据判断耳机是否处于佩戴状态。例如，可以通过将来自传感器的数据转换成数字信号，并将转换后的数字信号与关于特定的运动模式的数据进行比较来判断耳机是否处于佩戴状态。在步骤704，根据步骤703的判断结果，输出用于指示所述耳机是否处于佩戴状态的控制信号。
图8是根据本申请的音频信号输出模式切换方法的流程图。如图8所示，根据本申请的音频信号输出模式切换方法包括：步骤801，接收耳机发送的用于指示所述耳机是否处于佩戴状态的控制信号；以及步骤802，根据所述控制信号切换音频输出模式。
具体地，根据所述控制信号切换音频输出模式的步骤可以包括：当所述控制信号为指示耳机处于非佩戴状态的控制信号，则确定当前音频输出模式为通过扬声器输出音频信号的第一音频输出模式；当所 述控制信号为指示耳机处于佩戴状态的控制信号，则确定当前音频输出模式为通过耳机输出音频信号的第二音频输出模式。
根据本申请的显示装置包括根据本申请的音频输出装置。根据本申请的显示装置还可以包括与所述音频输出装置可拆卸连接的耳机，所述耳机为根据本申请的耳机。
显示装置可以为任何具有显示功能的产品或部件，例如手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等，或者可以为用于例如可穿戴显示设备、医疗设备等的显示面板。根据本申请的显示装置尤其包括薄型显示装置，因为这些薄型显示装置的耳机插孔变得越来越小，使得目前的耳机越来越不容易插入这些薄型显示装置的耳机插孔。
显然，本领域的技术人员可以对本申请实施例进行各种修改和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些修改和变型在内。
