Description

一种佩戴检测方法及相关装置
本申请要求于2022年03月28日提交中国专利局、申请号为202210310203.5、申请名称为“一种佩戴检测方法及相关装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种佩戴检测方法及相关装置。
背景技术
随着用户消费升级，头戴式设备市场规模逐渐庞大。头戴式设备的目的是探索全新的人机交互方式，智能设备通过穿戴在人体之上为消费者提供专属的、多功能、个性化、更便利的服务。
目前，无论用户是否佩戴头戴式设备，都不会影响头戴式设备的工作状态，例如，当头戴式设备正在播放音频时，用户摘下该头戴式设备，该设备依旧会继续播放该音频。这样，会增加设备的耗能。
发明内容
本申请提供了一种佩戴检测方法及相关装置。头戴式设备可以通过扬声器发送超声波，通过麦克风接收超声波，并基于发送的超声波和接收的超声波，确定出头戴式设备的佩戴状态。实施本申请提供的显示方法，可以基于头戴式设备现有的器件进行佩戴检测，节约成本，并且由于头戴式设备没有增加其他用于佩戴检测的元器件，不会增加头戴式设备的重量，减少头戴式设备对用户颈椎的压力。由于超声波不能被人耳听到且不会对人体造成伤害，可以在用户没有察觉的情况下无感检测头戴式设备的佩戴情况。
第一方面，本申请实施例提供了一种头戴式设备，包括：第一扬声器，麦克风，处理器；
第一扬声器，用于发送第一超声波；麦克风，用于接收第二超声波，第二超声波为麦克风接收的第一超声波的至少一部分；当第一超声波的振幅和第二超声波的振幅之间的差值为第一值时，头戴式设备被配置为处于第一状态；当第一超声波的振幅和第二超声波的振幅之间的差值为第二值时，头戴式设备被配置为处于第二状态，其中，第一值与第二值不同。
这样，本申请实施例提供的头戴式设备可以更好地基于应用场景，更加智能地自动化控制头戴式设备的工作模式。
在一种可能的实现方式中，第一状态为已佩戴状态，第二状态为非佩戴状态。
在一种可能的实现方式中，头戴式设备处于第一状态的耗电量大于头戴式设备处于第二状态的耗电量。
这样，头戴式设备被配置为处于第二状态，头戴式设备的耗能降低，既可以节约头戴式设备的耗电量，延长头戴式设备的续航时间，也不会影响用户正常使用该头戴式设备。例如，头戴式设备被配置为处于已佩戴状态时，显示应用的界面，当头戴式设备被配置为未佩戴状态时，可以息屏(又称为灭屏，熄屏)。并且，当头戴式设备再次被配置为已佩戴状态时，可以点亮屏幕，继续显示息屏前显示的内容。
在一种可能的实现方式中，麦克风位于第一部件，第一扬声器位于第二部件，第一部件和第二部件不同，第一值大于第二值。
在一种可能的实现方式中，第一值的取值范围为40分贝-100分贝，和/或，第二值的取值范围为0分贝-40分贝。
在一种可能的实现方式中，麦克风和第一扬声器都位于第一部件，第一值小于第二值。
在一种可能的实现方式中，第一值的取值范围为0分贝-40分贝，和/或，第二值的取值范围为40分贝-100分贝。
在一种可能的实现方式中，麦克风，还用于在第一扬声器发送第一超声波之前，接收非第一扬声器发送的第三超声波；第一超声波被配置为与第三超声波不同。
这样，由于头戴式设备提前获取了环境中的第三超声波，并将第一超声波配置为和第三超声波不同，当头戴式设备附近还存在其他电子设备时，其他电子设备发出的超声波信号也不会影响头戴式设备的佩戴检测功能。
在一种可能的实现方式中，第一超声波被配置为与第三超声波不同，包括：第一超声波被配置为与第三超声波的频率不同和/或占空比不同。
在一种可能的实现方式中，第一超声波与第三超声波的频率不同，包括：第一超声波的频率和第三超声波的频率的差值大于第一频率差值。这样，可以避免将第三超声波误认为第一超声波，提高检测结果的准确度。
在一种可能的实现方式中，头戴式设备还包括第二扬声器；第二扬声器，用于发送可听声波信号，可听声波信号的频率和第一超声波的频率不同。这样，头戴式设备包括多个扬声器，可以满足用户需求(例如，听音乐、打电话等等)的同时，在用户没有察觉的情况下，检测头戴式设备的佩戴状态。
在一些实施例中，第一超声波的频率大于20000Hz，可听声波信号的频率大于0且小于等于20000Hz。
在一种可能的实现方式中，第一扬声器，具体用于在第一时间段内发送第一超声波；第二扬声器，具体用于在第一时间段内发送可听声波信号。这样，头戴式设备可以同时发送第一超声波和可听声波信号。
在一种可能的实现方式中，第一扬声器，具体用于在第一时间段内发送第一超声波，在第二时间段内发送可听声波信号，可听声波信号的频率和第一超声波的频率不同。
在一种可能的实现方式中，第一扬声器，还用于在第三时间段内发送第一超声波，在第四时间段内发送可听声波信号，第二时间段在第一时间段之后，第三时间段在第二时间段之后，第四时间段在第三时间段之后。这样，头戴式设备可以在发送第一超声波期间，间隔发送第一超声波和可听声波信号。由于听觉暂留现象，用户可以将间隔播放的可听声波信号误会为连续播放的，不影响用户使用头戴式设备的音频播放功能。
在一种可能的实现方式中，所述第一时间段和所述第二时间段周期性间隔发送，所述第一时间段的范围包括5ms至15ms，所述第二时间段的范围包括20ms至40ms。例如，第一时间段包括第一扬声器发送第一超声波期间每33ms中的前10ms，第二时间段包括33ms中的后23ms，即第一扬声器发送第一超声波10ms，第一扬声器发送可听声波信号23ms；之后，第一扬声器再发送第一超声波10ms，第一扬声器再发送可听声波信号23ms；如上循环发送第一超声波和可听声波信号。既可以保证第一超声波的发送，也不会影响用户感知到的可听声波信号的连续性。
在一种可能的实现方式中，第一扬声器，还用于在发送第一超声波之前，发送前缀信号，前缀信号用于标识第一超声波。这样，可以便于头戴式设备基于前缀信号，识别第一超声波。
在一种可能的实现方式中，头戴式设备的设备类型包括以下任意一种：智能眼镜，头罩 式耳机，增强现实AR眼镜，虚拟显示VR眼镜，混合现实MR眼镜，智能头盔。
在一种可能的实现方式中，头戴式设备为眼镜，第一部件为左侧眼镜腿，第二部件为右侧眼镜腿，或者，第一部件为右侧眼镜腿，第二部件为左侧眼镜腿，或者，第一部件为鼻托，第二部件为左侧眼镜腿，或者，第一部件为鼻托，第二部件为右侧眼镜腿。
在一种可能的实现方式中，头戴式设备为AR眼镜，处理器，还用于在头戴式设备被配置为处于第一状态或第二状态之前，播放第一视频；处理器，还用于在头戴式设备被配置为处于第一状态之后，继续播放第一视频；处理器，还用于在头戴式设备被配置为处于第二状态之后，暂停播放第一视频。
这样，既可以避免头戴式设备在未佩戴状态时继续播放该第一视频，减少头戴式设备的耗电量，还可以在头戴式设备再次切换为已佩戴状态时，继续播放音频文件中用户还未观看的部分，提升用户体验。
在一种可能的实现方式中，处理器，还用于在头戴式设备被配置为处于第一状态或第二状态之前，播放第一音频；处理器，还用于在头戴式设备被配置为处于第一状态之后，继续播放第一音频；处理器，还用于在头戴式设备被配置为处于第二状态之后，暂停播放第一音频。
这样，既可以避免头戴式设备在未佩戴状态时继续播放该音频文件，减少头戴式设备的耗电量，还可以在头戴式设备再次切换为已佩戴状态时，继续播放音频文件中用户还未收听的部分，提升用户体验。
在一种可能的实现方式中，头戴式设备还包括接近传感器，接近传感器包括电容传感器、惯性测量单元；接近传感器，用于在检测到用户靠近头戴式设备的操作后，通知第一扬声器发送第一超声波。
这样，可以进一步提高佩戴检测结果的准确性。

具体实施方式
虽然本申请的描述将结合一些实施例一起介绍，但这并不代表此申请的特征仅限于该实施方式。恰恰相反，结合实施方式作为申请介绍的目的是为了覆盖基于本申请的权利要求而有可能延伸出的其它选择或改造。为了提供对本申请的深度了解，以下描述中将包含许多具体的细节。本申请也可以不使用这些细节实施。此外，为了避免混乱或模糊本申请的重点，有些具体细节将在描述中被省略。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗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”的特征可以明示或者隐含地包括一个或者更多个该特征，另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或 多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
本申请提供了一种佩戴检测方法，应用于包括麦克风、处理器和扬声器的头戴式设备上。该头戴式设备可以通过扬声器发送第一超声波，通过麦克风接收第二超声波，第二超声波为麦克风接收的第一超声波的至少一部分。当第一超声波的振幅和第二超声波的振幅之间的差值为第一值时，头戴式设备被配置为处于第一状态。当第一超声波的振幅和第二超声波的振幅之间的差值为第二值时，头戴式设备被配置为处于第二状态。其中，第一值与第二值不同。
在本申请实施例中，第一状态可以为已佩戴状态，第二状态可以为非佩戴状态(又称为未佩戴状态)。头戴式设备处于第一状态的耗电量大于头戴式设备处于第二状态的耗电量。
在一些实施例中，头戴式设备的工作模式可以包括第一模式和第二模式，第一模式和第二模式不同。处于第一模式的头戴式设备的耗电量大于处于第二模式的头戴式设备的耗电量。例如，当头戴式设备处于第二模式时，和第一模式相比，头戴式设备可以停止后台程序的运行(包括后台程序的刷新、下载等)，暂停播放音频，减弱播放音频的音量，断开和其他电子设备之间的通信连接等等。当头戴式设备被配置为第一状态时，工作在第一模式。当头戴式设备被配置为第二状态时，工作在第二模式。
这样，基于超声波检测用户是否佩戴头戴式设备，可以使用头戴式设备现有的器件进行佩戴检测，节约成本，并且由于头戴式设备没有增加其他用于佩戴检测的元器件，不会增加头戴式设备的重量，减少头戴式设备对用户颈椎的压力。由于超声波不能被人耳听到且不会对人体造成伤害，可以在用户没有察觉的情况下无感检测头戴式设备的佩戴情况。同时，应用了本申请提供的佩戴检测方法的头戴式设备可以更好地基于应用场景，更加智能地自动化控制头戴式设备的工作模式。也就是说，头戴式设备可以基于检测得到的头戴式设备的佩戴情况，在第一模式和第二模式中自动切换，降低头戴式设备的耗能，例如，头戴式设备在已佩戴状态时，播放音频文件，当头戴式设备检测出头戴式设备从已佩戴状态切换为未佩戴状态时，可以自动暂停播放该音频文件。并且，当头戴式设备检测出头戴式设备从未佩戴状态再次切换为已佩戴状态时，可以自动继续播放该音频文件。这样，既可以避免头戴式设备在未佩戴状态时继续播放该音频文件，减少头戴式设备的耗电量，还可以在头戴式设备再次切换为已佩戴状态时，继续播放音频文件中用户还未收听的部分，提升用户体验。再例如，头戴式设备在已佩戴状态时，显示应用的界面，当头戴式设备检测出头戴式设备从已佩戴状态切换为未佩戴状态时，可以息屏(又称为灭屏，熄屏)。并且，当头戴式设备检测出头戴式设备从未佩戴状态再次切换为已佩戴状态时，可以点亮屏幕，继续显示息屏前显示的内容。
本申请实施例涉及的头戴式设备可以为包括扬声器、麦克风和处理器的眼镜，例如，智能眼睛，佩戴在用户头部，除了具备普通眼镜具备的光学矫正、调节可视光线或装饰等功能，还可以具备通信功能。例如，该头戴式设备可以和其他电子设备(例如，手机、电脑等)建立通信连接，该通信连接可以包括有线连接和无线连接。比如，无线连接可以为无线保真(wireless fidelity，Wi-Fi)连接、蓝牙(bluetooth)连接等近距离传输技术。有线连接可以为通用串行总线(universal serial bus，USB)连接、高清多媒体接口(high definition multimedia  interface，HDMI)连接等。本实施例对通信连接的类型不作限制。该头戴式设备可以通过这些通信连接方式和其他电子设备进行数据传输。例如，当头戴式设备和通讯设备之间建立有通信连接时，当该通讯设备和其他通讯设备通电话时，可以通过头戴式设备接听通话。再例如，头戴式设备可以插入移动运营商提供的芯片(例如，用户标识(subscriberidentitymodule，SIM)卡)，通过该芯片接听、拨打电话等等。
不限于智能眼镜，本申请实施例涉及的头戴式设备还可以是其他头戴式设备，例如可以为具有增强现实(augmentedreality，AR)、虚拟现实(virtualreality，VR)或混合现实(mixedreality，MR)等技术的头戴式显示设备，或智能头盔，或头罩式(头戴式)耳机等等，本申请实施例对此不作限制。
在本申请实施例中，头戴式设备可以基于佩戴检测方法，在检测到用户未佩戴该头戴式设备时，暂停/停止头戴式设备正在执行的任务，例如，当用户在通话时，检测到用户摘下头戴式设备，暂停通话等等。
参见图1，图1示出了一种电子设备100的结构示意图。在本实施例中，电子设备100示例为包括有麦克风和扬声器的眼镜。
如图1所示，电子设备100可以包括眼镜本体101和设于眼镜本体上的麦克风106、扬声器107和处理器(未示出)等等。
其中，眼镜本体101可以包括眼镜腿102、眼镜框103、显示装置104和鼻托105。显示装置104嵌于眼镜框103中。
眼镜腿102用于支撑用户将电子设备100佩戴在头部。常见的，眼镜框103包括两个眼镜框，眼镜腿102包括两个镜腿，两个镜腿分别设于两个眼镜框的后方位置，鼻托105设于两个眼镜框中间。用户佩戴电子设备100时，两个镜腿分别架于用户的两个耳朵上，鼻托105架于用户的鼻子上。
显示装置104用于用户观看真实世界物体和/或虚拟画面。显示装置104可以是透明镜片或其他颜色的镜片，可以是带有光学矫正功能的眼镜镜片，可以是具备可调节滤光功能的镜片，可以是墨镜或其他具有装饰效果的镜片。显示装置104还可以是显示屏或投影装置，可以产生光学信号，并将光学信号映射到用户眼睛中。本实施例对显示装置104的类型不作限制。在一些实施例中，可能不存在显示装置104，即眼镜本体101只包括眼镜腿102、眼镜框103和鼻托105。
在一些实施例中，当该头戴式设备为AR眼镜时，显示装置104既包括眼镜镜片，又包括显示屏或投影装置。在另一些实施例中，当该头戴式设备为VR眼镜时，显示装置104为显示屏。
麦克风106设于眼镜本体101上，例如，麦克风106可以设于眼镜腿102上，或者鼻托105上。麦克风106用于采集声音信号，比如用户的语音信息。电子设备100可以通过麦克风106采集用户语音信息，并解析生成对应的控制指令。或者，电子设备100可以通过麦克风106采集用户语音信息，并将其发送给其他电子设备，进行语音交流。
扬声器107设于眼镜本体101上，例如，扬声器107可以设于眼镜腿102上。扬声器107可以用于播放音频。
处理器(未示出)可以用于解析信号或生成指令，以及处理数据、协调调度进程等。
在本申请实施例中，扬声器107可以用于播放超声波，麦克风106可以用于采集该超声波，并将采集结果发送至处理器。处理器可以基于麦克风106采集的超声波信号，判断用户是否佩戴电子设备100。
可以理解的是，以上描述的电子设备100的结构仅为示例说明，并不对本申请其他实施例构成限制。

接下来结合应用场景介绍本申请实施例提供的一种佩戴检测方法。
在一些应用场景中，电子设备100的麦克风和扬声器位于电子设备100的眼镜本体上的不同部件上。电子设备100开启后，电子设备100的扬声器可以发送超声波，电子设备100的麦克风可以接收该扬声器发送的超声波。由于已佩戴状态的电子设备100接收的超声波的振幅和未佩戴状态的电子设备100接收的超声波的振幅不同，电子设备100可以基于发送的超声波的振幅，判断用户是否佩戴电子设备100。
示例性的，电子设备100的麦克风和扬声器可以分别处于图1所示的眼镜腿102的两个眼镜腿上面向用户的一侧，例如，麦克风可以位于眼镜腿102的左侧眼镜腿，扬声器可以位 于眼镜腿102的右侧眼镜腿。当电子设备100处于未佩戴状态时，如图3中的(a)所示，电子设备100的麦克风和扬声器处于不同侧位置，电子设备100的扬声器发送的超声波没有被阻挡，电子设备100的麦克风可以接收到大部分扬声器发送的超声波，此时，麦克风接收的超声波的振幅可以为A1。当电子设备100处于佩戴状态时，如图3中的(b)所示，电子设备100的麦克风和扬声器处于同侧位置，电子设备100的扬声器发送的超声波被用户的头部阻挡，即，扬声器发送的部分的超声波被用户的头部反射，无法被麦克风接收，电子设备100的麦克风只能接收到小部分扬声器发送的超声波，此时，麦克风接收的超声波的振幅可以为A2。其中，A1大于A2。
因此，电子设备100的麦克风和扬声器处于不同侧位置时，电子设备100处于佩戴状态时的麦克风接收到的电子设备100的扬声器发送的超声波的振幅比电子设备100处于未佩戴状态时麦克风接收到的超声波的振幅小。这样，电子设备100可以基于超声波信号的振幅确定出用户是否佩戴电子设备100。
接下来介绍本申请实施例中提供的一种佩戴检测方法的流程示意图。
在一种可能的实现方式中，电子设备100的麦克风和扬声器分别位于电子设备100的不同部件上。当电子设备100处于已佩戴状态时，电子设备100的麦克风和扬声器之间被遮挡，当电子设备100处于未佩戴状态时，电子设备100的麦克风和扬声器之间无遮挡。电子设备100可以通过扬声器发送超声波，通过麦克风接收超声波，并基于接收的超声波，确定出电子设备100为已佩戴状态或者未佩戴状态。电子设备100处于已佩戴状态时，可以在第一模式下工作。电子设备100处于未佩戴状态时，可以在第二模式下工作。这样，使用电子设备100现有的扬声器和麦克风进行佩戴检测，节约制造成本，并且，由于电子设备100没有增加其他用于佩戴检测的元器件，不会增加电子设备100的重量，减少电子设备100对用户颈椎的压力。由于超声波不能被人耳听到且不会对人体造成伤害，可以在用户没有察觉的情况下无感检测电子设备100的佩戴状态。同时，电子设备100可以更好地基于应用场景，更加智能地自动化控制电子设备100的工作模式。在一些实施例中，在已佩戴状态时，电子设备100可以在第一模式下工作，当电子设备100工作在第一模式时，电子设备100可以正常播放音频，和其他电子设备建立用于交换数据的通信连接等，便于用户使用。在未佩戴状态时，电子设备100可以在第二模式下工作，当电子设备100工作在第二模式时，电子设备100可以电子设备100可以暂停播放音频，断开和其他电子设备之间的通信连接等，降低电子设备100的耗电量。
示例性的，如图4所示，该显示方法包括如下步骤：
S401.电子设备100启动。
在一些实施例中，当电子设备100接收到用户开启电子设备100的输入(例如，针对开机按键的输入)后，响应于该输入，电子设备100启动。电子设备100启动后，可以执行步骤S402。
需要说明的是，不限于电子设备100接收用户开启电子设备100的输入时，电子设备100启动。当电子设备100从待机模式或休眠模式切换至工作模式时，也可以理解为电子设备100启动。例如，电子设备100检测电子设备100的眼镜腿从折叠形态(即，电子设备100的两个眼镜腿互相贴合)切换至展开形态(即，电子设备100的两个眼镜腿相互分离，如图1所示)，电子设备100启动。其中，电子设备100可以基于IMU等传感器检测眼镜腿的运动，确定出眼镜腿切换至展开形态。再例如，电子设备100可以在通过IMU等传感器检测到电子设备100的位置发生改变时，电子设备100启动。
在一些实施例中，电子设备100的眼睛本体靠近用户的一侧设置有接近传感器(例如，接近光传感器，电容传感器，红外传感器，IMU传感器等)。当电子设备100通过接近传感器确定出用户靠近电子设备100时，电子设备100启动。
在一些实施例中，电子设备100和充电仓连接，电子设备100置于充电仓的内部，当电子设备100脱离充电仓时，电子设备100启动。
S402.电子设备100的扬声器发送超声波。
电子设备100的扬声器可以发送超声波信号。其中，电子设备100发送的超声波信号可以称为检测信号，目标超声波信号等等。电子设备100可以通过以下几种方式，得到检测信号。
1.电子设备100中存储有M种检测信号，其中，M为正整数。电子设备100可以发送该M种检测信号中的一种检测信号。
其中，该M种检测信号的波形不同。其中，波形不同可以理解为频率、占空比等中的一种或多种不同。具体的，当检测信号只包括一种频率的波形时，两种检测信号的频率不同即为两种检测信号的频率不同。例如，一种检测信号的频率为f1，另一种检测信号的频率为f2，f1和f2不同，两种检测信号不同。当检测信号包括多种频率的波形时，两种检测信号的频率不同可以理解为两种检测信号的频率组成和/或排列不同，例如，第一种检测信号由频率为f1的波形和频率为f2的波形组成。第二种检测信号由频率为f2的波形和频率为f1的波形组成。第三种检测信号由频率为f1的波形和频率为f3的波形组成。第一种检测信号和第二种检测信号都包括频率为f1的波形和频率为f2的波形，但这两种检测信号的排列顺序不同，该两种检测信号不同。第一种检测信号和第三种检测信号包括的波形的组成不同，其中，第一种检测信号包括频率为f2的波形，不包括频率为f3的波形，第三种检测信号包括频率为f3的波形，不包括频率为f2的波形，这两种检测信号的组成不同，该两种检测信号不同。
其中，占空比为一个周期的波形中振幅为零的波形和一个周期的波形的比例。其中，占空比可以由百分数或分数表示，取值范围在0到1之间。
具体的，当检测信号只包括一种占空比的波形时，两种检测信号的占空比不同即为两种检测信号的占空比的值不同。例如，一种检测信号的占空比为w1，另一种检测信号的占空比为w2，w1和w2不同，两种检测信号不同。当检测信号包括多种占空比的波形时，两种检测信号的占空比不同可以理解为两种检测信号的占空比组成和/或排列不同。
在一些实施例中，两种波形不同还包括振幅为0的波形在一个周期内的位置不同。具体的，当两种检测信号的占空比都为25％时，第一种检测信号的振幅为0的波形处在一个周期的第一个T/4时间内，第二种检测信号的振幅为0的波形处在一个周期的最后一个T/4时间内，两种检测信号不同。
在另一些实施例中，为了便于区别两种检测信号。振幅为0的波形始终出现在一个周期的波形的开始或末尾。
可选的，两种检测信号不同为两种检测信号的振幅不同。
示例性的，电子设备100可以以Cm，m∈{1,2，…，M}标识该M种检测信号。例如，该M种检测信号的波形图可以参见如图5所示的波形图示例。其中，检测信号c1的占空比为0％，周期为T1。检测信号c2的占空比为0％，周期为T2。检测信号cm-1的占空比为25％，周期为T1。检测信号cm的占空比为25％，周期为T2。其中，检测信号c1和检测信号c2的周期(即，频率)不同，检测信号c1和检测信号cm-1的占空比不同，检测信号c1和检测信号cm的占空比和周期都不同。也就是说，超声波集合Cm中的任意两段超声波的振幅和/或频率不 同。
在一些实施例中，为了便于区分检测信号，M种检测信号中所有检测信号的振幅、占空比相同，频率不同。
在一些实施例中，电子设备100存储有M种检测信号的频率和振幅，电子设备100可以基于频率和振幅得到扬声器播放的超声波信号。例如，电子设备100可以以列表的形式存储超声波信号，例如，检测信号c1可以以{c1，21000，100}表示，其中，c1为该超声波信号的标识。21000为超声波信号的频率，该频率值的单位可以为Hz。100为超声波信号的振幅，该振幅值的单位可以为分贝(decibel，dB)。这样，电子设备100可以基于该列表确定出超声波信号的频率和振幅，即，确定出超声波信号的波形。同理，电子设备100存储有M种检测信号的频率、占空比和振幅，电子设备100可以基于频率、占空比和振幅得到扬声器播放的超声波信号。
在另一些实施例中，电子设备100存储有M种检测信号的波形对应的数字音频信息。电子设备100可以基于存储的数字音频信息，得到数字音频信号对应的模拟音频信号，即，超声波信号。
其中，电子设备100在发送M种检测信号中的一种检测信号时，可以随机选取M种检测信号中的某一种段检测信号进行发送，例如，电子设备100可以发送Cm中的Ci，其中，i大于1，且小于等于m。或者，电子设备100可以按照存储M种检测信号的顺序，依次发送M种检测信号中的某一种检测信号。例如，电子设备100可以在第一次执行步骤S402时，发送检测信号c1，在第二次执行步骤S402时，发送检测信号c2，以此类推。
进一步的，为了避免其他电子设备的干扰，电子设备100可以在发送检测信号之前，通过麦克风接收附近的声波信号，并且，从存储的检测信号中筛选出和附近的声波信号波形不同的检测信号，并发送该检测信号。
示例性的，接下来以频率为示例，介绍电子设备100确定出检测信号的具体步骤。具体的，如图6所示：
S601.电子设备100接收附近的声波信号。
电子设备100可以通过麦克风接收附近的声波信号。
S602.电子设备100判断附近的声波信号中是否包括存储的M种超声波中的N种信号，0<N<M。
电子设备100可以基于接收的声波信号的频率，判断附近的声波信号是否包括M种检测信号中的N种检测信号。具体的，电子设备100可以将附近的声波信号和M种检测信号的频率一一进行对比，确定出M种检测信号中和附近的声波信号频率相同的N种信号。其中，0<N<M。M种检测信号中和附近的声波信号频率相同的N种信号为附近的声波信号包括的N种信号。
需要说明的是，当附近的声波信号的频率和检测信号的频率的差值小于第一频率差值(例如，30Hz)时，就可以认为附近的声波信号和检测信号相同。
当电子设备100判定出附近的超声波信号中包括存储的M种检测信号中的N种信号时，可以执行步骤S603。当电子设备100判定出附近的超声波信号中不包括存储的M种检测信号中的N种信号时，可以执行步骤S604。
在一些实施例中，附近的声波信号和检测信号的频率和振幅都相同时，认为附近的声波信号和检测信号相同。其中，当附近的声波信号的频率和检测信号的频率的差值小于第一频率差值时，附近的声波信号的频率和检测信号的频率相同。当附近的声波信号的振幅和检测 信号的振幅的差值小于预设振幅差值(例如，10dB)时，附近的声波信号的振幅和检测信号的振幅相同。
S603.电子设备100发送M种检测信号中除了检测到的N种检测信号以外的任意一种检测信号。
电子设备100可以排除M种检测信号中和附近的声波信号相同的N种检测信号，并选取剩余的检测信号中任一种检测信号进行发送。
S604.电子设备100发送M种检测信号中任意一种检测信号。
电子设备100可以随机发送检测信号中任一种检测信号。
可选的，电子设备100可以获取附近的声波信号的频率，发送M种检测信号中频率和附近的声波信号不同的检测信号。
在一些实施例中，M种检测信号的振幅相同，频率不同。
2.电子设备100可以随机生成检测信号。
在一些实施例中，电子设备100可以随机生成检测信号的频率和振幅的值，再基于频率值和振幅值生成对应的检测信号。其中，检测信号的频率的值处于指定频率范围(例如，20000Hz-24000Hz)内，检测信号的振幅的值处于指定振幅范围(例如，80dB-120dB)内。
进一步的，为了避免其他电子设备的干扰，电子设备100可以在生成检测信号之前，通过麦克风获取附近的声波信号，并确定出附近的声波信号的频率。再生成和附近的声波信号的频率不同的检测信号。
在一种可能的实现方式中，为了更好地区分电子设备100发送的检测信号，电子设备100可以在发送检测信号前，发送前缀信号。电子设备100可以基于前缀信号确定出该前缀信号属于电子设备100发送的超声波信号，即，确定出发送的检测信号，电子设备100可以基于前缀信号和检测信号确定出用户是否佩戴电子设备100。其中，前缀信号和检测信号可以相同，也可以不同。当前缀信号和超声波信号相同时，该前缀信号和超声波信号之间可以存在一段空白时间间隔。其中，空白时间间隔的长度为固定值，例如，可以为2ms。
示例性的，图7示出了前缀信号的示例图像。如图7中的(a)所示，前缀信号和检测信号相同，前缀信号和检测信号之间存在有空白时间间隔。如图7中的(b)所示，前缀信号和检测信号不相同，前缀信号和检测信号相接。如图7中的(c)所示，前缀信号和检测信号不相同，前缀信号和检测信号之间存在有空白时间间隔。这样，电子设备100可以基于前缀信号的波形确定出该前缀信号和检测信号为用于检测用户是否佩戴电子设备100的信号，并基于确定出的前缀信号和检测信号判断用户是否佩戴电子设备100，避免附近的声波信号对检测结果的干扰。
可选的，电子设备100可以基于前缀信号确定出检测信号，再基于检测信号进行佩戴检测。
可选的，电子设备100发送的检测信号可以由多段频率不同的超声波信号拼接得到。这样，电子设备100可以通过多段频率不同的超声波信号，共同检测用户是否佩戴电子设备100，进一步确保检测结果的正确性。
在一种可能的实现方式中，电子设备100可以基于多种不同的波形组成检测信号。示例性的，当电子设备100包括两种波形，波形A和波形B时，电子设备100可以通过波形A和波形B的组合排序确定出检测信号。例如，当一段检测信号由4段波形组成时，当检测信号由波形A，波形A，波形B和波形A组成时，该检测信号可以表示为AABA。可以理解的是，当电子设备100只包括两种波形时，可以由二进制数标识该两种波形，便于理解。例如，可 以通过二进制数字0标识波形A，通过二进制数字1标识波形B，那么检测信号AABA可以表示为0010。这样，电子设备100存储的M种检测信号，即可以表示为存储有M种字符串，以及字符串中每一个字符对应的波形。
可选的，电子设备100可以只存储有N个字符和该N个字符对应的N种波形。电子设备100可以随机生成由该N个字符中任意字符组成的字符串，得到检测信号。
S403.电子设备200的麦克风接收超声波。
当电子设备100通过扬声器发送检测信号时，可以通过麦克风接收附近的声波信号，附近的声波信号包括扬声器发送的检测信号。
S404.电子设备100判断接收的超声波的振幅是否超过第一阈值。
电子设备100可以针对接收的检测信号，进行傅里叶变换处理，得到接收的检测信号的振幅值。当检测信号的振幅大于第一阈值时，电子设备100可以执行步骤S406。当检测信号的振幅小于或等于第一阈值时，电子设备100可以执行步骤S405。其中，第一阈值的值可以为发送的检测信号的振幅值和第一系数的乘积。其中，第一系数可以为大于0，且小于等于1的分数值。在一些实施例中，第一系数可以为50％至80％之间的百分数。在一些实施例中，第一阈值的值为固定值，该固定值可以电子设备100的制造厂家进行设置。
在一些实施例中，电子设备100可以在接收到附近的模拟音频信号后，将模拟音频信号转换成数字音频信号，并针对数字音频信号进行傅里叶变换处理，得到附近的音频信号的频率和振幅的对应关系。电子设备100可以基于发送的检测信号的频率，确定出接收的检测信号。再基于附近的音频信号的频率和振幅的对应关系，确定出接收的检测信号的振幅。电子设备100可以基于该振幅的值是否大于第一阈值，确定出用户是否佩戴电子设备100。在此，电子设备100接收的附近的声波信号中和发送的检测信号的频率相同的声波信号为检测信号。在一些实施例中，两个信号的频率的差值小于第一频率差值时，两个信号的频率相同。
示例性的，电子设备100发送的检测信号为x(t)时，接收的检测信号的振幅值可以表示为x[n]，对x[n]进行离散傅里叶变换的公式为：
其中，X[k]是频率为k的检测信号中第n个采样点的振幅值，x[n]为检测信号中第n个采样点的振幅值，N为采样点的总数量，j为复数。
在一些实施例中，检测信号的振幅在20dB-150dB之间，例如，可以为100dB。在一些实施例中，检测信号的频率在20000Hz-40000Hz之间，例如，可以为20000Hz。
例如，当电子设备100的扬声器发送的检测信号的频率为20000Hz，振幅为100dB时，当电子设备100的麦克风和扬声器之间没有障碍物阻挡时，电子设备100的麦克风可以基于160KHz采样频率采集检测信号。其中，在0.2ms中扬声器发送的检测信号和麦克风采集的检测信号的时域图像可以如图8A所示。电子设备100在0.2ms时间内发送的检测信号的波形可以如图8A中的(a)所示。电子设备100在0.2ms的时间内针对图8A中的(a)示出的检测信号进行采样，得到32个采样点，该32个采样点组成了如图8A中(b)所示的离散波形。基于上述离散傅里叶变化的公式(1)，电子设备100的麦克风得到的离散波形进行傅里叶变换的公式如下，
其中，采样点的总数量N为32。由此公式(2)，可以得到检测信号的频域图像。电子设备100接收的检测信号的频域图像可以如图8B所示。根据图8B示出的检测信号的频域图像， 可以确定出电子设备100的麦克风采集的检测信号的频率为20000Hz，振幅为100dB。
接下来介绍在一些实际的应用场景中，电子设备100的麦克风采集的声波信号的图像。例如，若电子设备100发送的检测信号的频率为20000Hz，振幅为100dB，第一阈值的值为60dB。如图8C中的(a)所示，电子设备100采集的声波信号中频率为20000Hz的声波信号为检测信号。该检测信号的频率为20000Hz，振幅为100dB。电子设备100接收的检测信号的振幅大于第一阈值。电子设备100可以判定出用户未佩戴电子设备100。
需要说明的是，图8C中的(a)示出的电子设备100接收到的检测信号的振幅和电子设备100发送的检测信号的振幅的值仅为示例，由于麦克风和扬声器之间存在介质，接收的检测信号的振幅值可以小于或等于发送的检测信号的振幅值，本申请实施例对此不作限定。
如图8C中的(b)所示，电子设备100采集的声波信号中频率为20000Hz的声波信号为检测信号。该检测信号的频率为20000Hz，振幅为50dB。电子设备100接收的检测信号的振幅的值小于第一阈值。电子设备100可以判定出用户已佩戴电子设备100。
在一种可能的实现方式中，电子设备100可以基于电子设备100的电量设置发送的检测信号的振幅值以及第一阈值。例如，当电子设备100的电量较少(例如，小于20％)时，电子设备100可以降低发送的检测信号的振幅和第一阈值的值，从而减少电子设备100进行佩戴检测的耗电量，进一步节约电子设备100的功耗。
可选的，当接收的检测信号的振幅大于或等于第一阈值时，电子设备100可以判定出用户未佩戴电子设备100，可以执行步骤S406。当超声波的振幅小于第一阈值时，电子设备100可以判定出用户已佩戴电子设备100，执行步骤S405。

可选的，第一范围可以表示为[0，A*x)或(0，A*x)，其中，x为大于0小于1的系数。
可选的，第一范围可以表示为[k，A*x)或(k，A*x)，其中，k大于等于0且小于A*x。
在一种可能的实现方式中，电子设备100可以基于发送的检测信号的振幅和接收的检测信号的振幅的差值确定出电子设备100的佩戴状态。具体的，当该发送的检测信号的振幅和接收的检测信号的振幅的差值为第一值时，确定出电子设备100处于已佩戴状态。当该发送的检测信号的振幅和接收的检测信号的振幅的差值为第二值时，确定出电子设备100处于非佩戴状态。
在一些实施例中，第一值的取值范围为[0，A*x]或(0，A*x]，第二值的取值范围为(A*x，100]或(A*x，100)。其中，A为发送的检测信号的振幅值，x为大于0且小于1的系数。例如，当发送的检测信号的振幅值为100dB，且，x为0.4时，第一值的取值范围可以为0dB-40dB，第二值的取值范围可以为40dB-100dB。
可选的，第一值的取值范围为[k，A*x]或(k，A*x]，第二值的取值范围为(A*x，p]或(A*x，p)。其中，k大于等于0且小于A*x，p大于A*x且小于等于100。
在一种可能的实现方式中，电子设备100可以基于接收的检测信号的振幅和发送的检测信号的振幅的百分比确定出电子设备100的佩戴状态。具体的，当该接收的检测信号的振幅和发送的检测信号的振幅的百分比为第三值时，确定出电子设备100处于已佩戴状态。当该接收的检测信号的振幅和发送的检测信号的振幅的差值为第四值时，确定出电子设备100处于非佩戴状态。
在一些实施例中，第三值的取值范围为[0％，y％]或(0％，y％]，第四值的取值范围为(y％，100％]或(y％，100％)。其中，y大于0且小于100。例如，当y为60时，第三值的取值范围可以为0％-60％，第二值的取值范围可以为60％-100％。
可选的，第三值的取值范围为[a％，y％]或(a％，y％]，第四值的取值范围为(y％，b％]或(y％，b％)。其中，a大于等于0且小于y，b大于y且小于等于100。
S405.电子设备100处于已佩戴状态，电子设备100在第一模式下工作。
电子设备100在步骤S402-步骤S404中基于接收的检测信号的振幅确定出电子设备100处于已佩戴状态。电子设备100在第一模式下工作。由于相比于第二模式，处于第一模式的电子设备100耗电量更大，可以更加快速高效地执行用户的指令，便于用户使用。
电子设备100执行步骤S405后，可以继续执行步骤S402。
可选的，电子设备100执行步骤S405后，可以相隔预设空闲时间(例如，20ms)，再执行步骤S402。这样，可以减少电子设备100发送/接收超声波的耗能。
需要说明的是，当电子设备100在第一模式下工作时，由于电子设备100的扬声器可以播放频率范围在20Hz-20000Hz之间的可听声波信号，用户可以听见该频率范围的可听声波信号。
在一些实施例中，为了用户可以收听麦克风发送的可听声波信号，电子设备100可以周期轮流发送检测信号和可听声波信号。具体的，电子设备100可以在第一个播放周期发送检测信号，在第二个播放周期发送可听声波信号，电子设备100可以在第三个播放周期发送检测信号，在第四个播放周期发送可听声波信号，……，等等。其中，该多个播放周期的时长可以相同，也可以不同。
例如，电子设备100可以在发送超声波信号的过程中，将每1s划分为30个33ms。其中，每一个33ms内，电子设备100可以播放23ms可听声波信号，再播放10ms检测信号。这样，由于听觉暂留现象，用户可以将间隔播放的可听声波信号误会为连续播放的。需要说明的是，当前划分方法仅为本申请实施例提供的示例，不应对检测信号和可听声波信号的发送时间构成限定。
