Description

耳机贴合度检测方法和耳机
本申请要求于2022年12月9日提交国家知识产权局、申请号为202211580027.3、发明名称为“耳机贴合度检测方法和耳机”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
本申请涉及电子技术领域，尤其涉及一种耳机贴合度检测方法和耳机。
背景技术
入耳式真实无线立体声(true wireless stereo，TWS)耳机可以通过耳机贴合度检测功能来判断用户的耳道与耳机是否贴合。耳机贴合度检测的基本原理是：当耳机中的扬声器部分插入用户的耳道后，耳机中的扬声器按照预设的耳机贴合度检测参数(例如降噪参数)播放一段预置音频，耳机中的麦克风(位于耳道外面)对环境音(其中包括了从耳道与耳机之间缝隙泄露的预置音频)进行收音，耳机通过分析播放的预置音频和接收到的泄漏的预置音频来确定预置音频的泄露值，该泄露值越小则用户的耳道与耳机越贴合。在一些场景下，在进行耳机贴合度检测期间，如果耳机播放其他声音或者改变了降噪参数，都会影响耳机贴合度检测的准确性，简称这种场景为耳机贴合度检测的互斥场景。
现有技术中，电子设备侧的耳机应用对这种互斥场景进行处理，但是对于电子设备的某些操作系统来说，耳机应用的权限有限，造成同一种耳机连接采用不同操作系统的电子设备后，在进行耳机贴合度检测时，对同一种互斥场景的处理方式不同，给用户造成困扰。
发明内容
本申请实施例提供一种耳机贴合度检测方法和耳机，用于实现由耳机对耳机贴合度检测的互斥场景进行处理，以提高耳机贴合度检测功能的兼容性。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种耳机贴合度检测方法，应用于耳机，该方法包括：从电子设备接收业务启动命令，业务启动命令用于指示耳机启动第一业务，第一业务指：改变耳机的降噪参数的业务，或者，播放除了耳机贴合度检测所需音频之外的其他音频的业务；启动第一业务；从电子设备接收贴合度检测命令，贴合度检测命令用于指示耳机进行耳机贴合度检测；如果确定正在进行的第一业务与耳机贴合度检测互斥，则禁止耳机贴合度检测。
本申请实施例提供的耳机贴合度检测方法，耳机已经在进行第一业务，第一业务可以改变耳机的降噪参数的业务，或者，播放除了耳机贴合度检测所需音频之外的其他音频，会导致耳机贴合度检测的准确性降低。此时，如果耳机接收到贴合度检测命令(贴合度检测命令用于指示耳机进行耳机贴合度检测)，则耳机禁止耳机贴合度检测(即不启动耳机贴合度检测)。因此，由耳机执行控制逻辑，通过降低耳机贴合度检测的优先级，来避免与第一业务冲突，不会依赖电子设备中操作系统开放给耳机应 用的权限，对于采用不同操作系统的电子设备来说，耳机对互斥场景的处理是一致的，因此可以提高耳机贴合度检测的兼容性。
在一种可能的实施方式中，第一业务包括以下业务中的至少一项：播放媒体业务、通话业务、播放长提示音业务、唤醒语音助手业务。
由于播放媒体业务、播放长提示音业务等会播放音频，通话业务、唤醒语音助手业务会因为需要采集语音并降低噪音而改变耳机的降噪参数，所以都会造成耳机贴合度检测的准确性降低。
在一种可能的实施方式中，第一业务为通话业务或唤醒语音助手业务，确定正在进行的第一业务与耳机贴合度检测互斥，包括：确定耳机的语音传输通道处于连接状态。
当耳机的语音传输通道处于连接状态时，表明电子设备正在通过耳机的语音传输通道与耳机传输通话业务或唤醒语音助手业务的音频数据。
在一种可能的实施方式中，语音传输通道为面向同步连接(synchronous connection oriented，SCO)通道。
本申请不限定语音传输通道的具体类型，随着协议演变还可以为其他类型的通道。
在一种可能的实施方式中，第一业务为播放媒体业务或播放长提示音业务，确定正在进行的第一业务与耳机贴合度检测互斥，包括：确定耳机的音频传输通道处于播放状态或暂停状态。
当耳机的音频传输通道处于播放状态或暂停状态时，表明电子设备正在通过耳机的音频传输通道与耳机传输播放媒体业务或播放长提示音业务的音频数据。
在一种可能的实施方式中，音频传输通道为高级音频分发配置文件(advanced audio distribution profile，A2DP)通道。
本申请不限定音频传输通道的具体类型，随着协议演变还可以为其他类型的通道。
在一种可能的实施方式中，在确定正在进行的第一业务与耳机贴合度检测互斥之后，该方法还包括：向电子设备发送第一错误指示信息，第一错误指示信息用于指示耳机禁止进行耳机贴合度检测。
使得电子设备可以提示用户，如果要进行耳机贴合度检测，则需要停止正在进行的与耳机贴合度检测互斥的第一业务，以避免降低耳机贴合度检测的准确性。
第二方面，提供了一种耳机贴合度检测方法，应用于耳机，该方法包括：从电子设备接收贴合度检测命令，贴合度检测命令用于指示耳机进行耳机贴合度检测；如果确定未在进行与耳机贴合度检测互斥的第一业务，则启动耳机贴合度检测，第一业务指：改变耳机的降噪参数的业务，或者，播放除了耳机贴合度检测所需音频之外的其他音频的业务；在完成耳机贴合度检测之前，如果从电子设备接收业务启动命令，则中断耳机贴合度检测并启动第一业务，业务启动命令用于指示耳机启动第一业务。
本申请实施例提供的耳机贴合度检测方法，当耳机已经在进行耳机贴合度检测时，如果接收到指示耳机进行与耳机贴合度检测互斥的第一业务的命令，则耳机中断耳机贴合度检测。与耳机贴合度检测互斥的第一业务可能改变耳机的降噪参数，或者，播放除了耳机贴合度检测所需音频之外的其他音频，导致耳机贴合度检测的准确性降低。因此，由耳机执行控制逻辑，通过降低耳机贴合度检测的优先级，来避免与第一业务 冲突，不会依赖电子设备中操作系统开放给耳机应用的权限，对于采用不同操作系统的电子设备来说，耳机对互斥场景的处理是一致的，因此可以提高耳机贴合度检测的兼容性。
在一种可能的实施方式中，第一业务包括以下业务中的至少一项：播放媒体业务、通话业务、播放长提示音业务、唤醒语音助手业务。
由于播放媒体业务、播放长提示音业务等会播放音频，通话业务、唤醒语音助手业务会因为需要采集语音并降低噪音而改变耳机的降噪参数，所以都会造成耳机贴合度检测的准确性降低。
在一种可能的实施方式中，第一业务为通话业务或唤醒语音助手业务，确定未在进行与耳机贴合度检测互斥的第一业务，包括：确定耳机的语音传输通道处于断开状态，并且，确定耳机的音频传输通道处于空闲状态。
当耳机的语音传输通道处于断开状态时，表明电子设备没有在通过耳机的语音传输通道与耳机传输通话业务或唤醒语音助手业务的音频数据。当耳机的音频传输通道处于空闲状态时，表明电子设备也没有在通过耳机的音频传输通道与耳机传输播放媒体业务或播放长提示音业务的音频数据。因此，不会造成耳机贴合度检测的准确性降低。
在一种可能的实施方式中，语音传输通道为SCO通道。本申请不限定语音传输通道的具体类型，随着协议演变还可以为其他类型的通道。
在一种可能的实施方式中，音频传输通道为A2DP通道。本申请不限定音频传输通道的具体类型，随着协议演变还可以为其他类型的通道。
在一种可能的实施方式中，第一业务为播放媒体业务或播放长提示音业务，业务启动命令为音频传输通道的状态切换命令，用于指示耳机将音频传输通道从空闲状态切换至播放状态或暂停状态。
即电子设备指示耳机将通过耳机的音频传输通道传输播放媒体业务或播放长提示音业务的音频数据，会降低耳机贴合度检测的准确性。
在一种可能的实施方式中，第一业务为通话业务或唤醒语音助手业务，业务启动命令为语音传输通道的状态切换命令，用于指示耳机将语音传输通道从空闲状态切换至连接状态。
即电子设备指示耳机将通过耳机的语音传输通道传输通话业务或唤醒语音助手业务的音频数据，会降低耳机贴合度检测的准确性。

处理器101可以包括一个或多个处理单元，不同的处理单元可以是独立的器件， 也可以集成在一个或多个处理器101中。处理器101具体可以是集成的控制芯片。处理器101可以用于执行上述指令，调用相关模块以执行本申请实施例涉及的耳机贴合度检测方法。处理器可以是一个芯片。例如，可以是现场可编程门阵列(field programmable gate array，FPGA)、专用集成芯片(application specific integrated circuit，ASIC)片上系统(system on chip，SoC)、中央处理器(central processor unit，CPU)、网络处理器(network processor，NP)、数字信号处理电路(digital signal processor，DSP)、微控制器(micro controller unit，MCU)、可编程控制器(programmable logic device，PLD)或其他集成芯片。
无线通信模块103可以用于支持通过无线通信技术(例如前文所述的蓝牙通信技术)实现耳机10与电子设备之间的数据传输。示例性的，该无线通信模块103可以包括蓝牙芯片，耳机10可以通过该蓝牙芯片与电子设备的蓝牙芯片之间进行配对并建立无线连接，以通过该无线连接实现耳机10和电子设备之间的无线通信。通常，蓝牙芯片可以支持基础速率(basicrate，BR)蓝牙、增强速率(enhanced data rate，EDR)蓝牙和BLE等。另外，无线通信模块103还可以包括天线，无线通信模块103经由天线接收电磁波，将电磁波信号调频以及滤波处理，将处理后的信号发送到处理器101。无线通信模块103还可以从处理器101接收待发送的信号，对其进行调频，放大，经天线转为电磁波辐射出去。
音频模块104可以用于管理音频数据，实现耳机10输入和输出音频流。例如，音频模块104可以从无线通信模块103获取音频流，或者向无线通信模块103传递音频流，实现通过蓝牙耳机进行通话、播放音乐、唤醒或关闭与耳机10连接的电子设备的语音助手、接收或发送用户的语音数据等功能。音频模块104可以包括用于输出音频流的扬声器(或称听筒、受话器)组件、麦克风(或称话筒，传声器)，与麦克风相配合的麦克收音电路等。扬声器可以将音频电信号转换成声音信号并播放。麦克风可以将声音信号转换为音频电信号。
图2示出的各种部件可以在包括一个或多个信号处理或专用集成电路在内的硬件、软件、或硬件和软件的组合中实现。示例性的，当该蓝牙耳机为TWS耳机时，该耳机10可以包括分别佩戴于左耳的耳机本体(也称左耳机)和佩戴于右耳的耳机本体(也称右耳机)。该耳机本体可以包括外壳和内部部件。内部部件设置于外壳形成的腔体内。内部部件可以包括上述音频模块、电源模块和无线通信模块等模块中的器件。
当蓝牙耳机为TWS耳机时，用户可以在双耳模式或单耳模式下使用TWS耳机。在单耳模式下，用户佩戴左耳机，或者佩戴右耳机，进行听音乐或通话等音频业务。在双耳模式下，用户可以佩戴两个耳机欣赏音乐或进行其他音频业务。在双耳模式下，两个耳机有主耳机和副耳机之分。并且，在TWS耳机的使用过程中，两个耳机的主、副角色还可以基于不同的条件进行切换，例如电量较高的耳机可以切换为主耳机，电量较低的耳机可以切换为副耳机。
电源模块105可以用于提供耳机10的系统电源，为耳机10各模块供电；支持耳机10接收充电输入等。电源模块105可以包括电源管理单元(power management unit，PMU)和电池。其中，电源管理单元可以接收外部的充电输入；将充电路输入的电信号变压后提供给电池充电，还可以将电池提供的电信号变压后提供给音频模块104、 无线通信模块103等其他模块；以及防止电池过充、过放、短路或过流等。在一些实施例中，电源模块105还可以包括无线充电线圈，用于对耳机10进行无线充电。另外，电源管理单元还可以用于监测电池容量，电池循环次数，电池健康状态(漏电、阻抗)等参数。

再例如，该传感器106还可以包括触摸传感器，用于检测用户的触摸操作；指纹传感器，用于检测用户指纹，识别用户身份等；环境光传感器，可以根据感知的环境光的亮度，自适应调节一些参数(如音量大小)；以及其他可能的传感器。
在一些实施例中，触摸传感器可以检测用户的单击、双击、多次点击、长按、重压等触摸操作，还可以进行用户指纹识别，以在支付交易等业务场景中对用户身份进行鉴权。
可以理解，图2所示的部件并不构成对耳机10的具体限定，耳机10还可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。
如图3所示，现有技术中耳机贴合度检测的流程是：
S101、耳机连接至电子设备。
并且用户佩戴耳机。用户可以在双耳模式或单耳模式下使用耳机。在单耳模式下，用户佩戴左耳机，或者佩戴右耳机，进行听音乐或通话等音频业务。在双耳模式下，用户可以佩戴两个耳机欣赏音乐或进行其他音频业务。在双耳模式下，两个耳机有主耳机和副耳机之分。
S102、用户在电子设备上点击耳机贴合度检测按钮。
在此期间，用户不能摘下耳机。用户在电子设备上点击耳机贴合度检测按钮后，电子设备向耳机发送贴合度检测命令，以指示耳机进行耳机贴合度检测。在双耳模式下，电子设备向主耳机发送贴合度检测命令，由主耳机转发给副耳机。
S103、耳机配置耳机贴合度检测参数。
示例性的，耳机贴合度检测参数包括降噪参数等。在双耳模式下，主耳机和副耳机分别配置各自的耳机贴合度检测参数。
S104、完成配置耳机贴合度检测参数之后，主耳机和副耳机进行预置音频的同步。
S105、耳机根据耳机贴合度检测参数(例如降噪参数)进行耳机贴合度检测。
在双耳模式下，主耳机和副耳机分别根据耳机贴合度检测参数进行耳机贴合度检测。
耳机贴合度检测的基本原理是：在耳机中的扬声器部分插入用户的耳道之后，耳机中的扬声器按照预设的降噪参数播放一段预置音频，耳机中的麦克风(位于耳道外 面)对环境音(其中包括了从耳道与耳机之间缝隙泄露的预置音频)进行收音，耳机通过分析播放的预置音频和接收到的泄漏的预置音频来确定预置音频的泄露值，该泄露值越小则用户的耳道与耳机越贴合。
S106、耳机将检测结果发送给电子设备。
在双耳模式下，副耳机通过主耳机的转发，将副耳机的检测结果发送给电子设备。
因此，在进行耳机贴合度检测期间，如果耳机播放其他声音或者改变了降噪参数，都会影响耳机贴合度检测的准确性。下面结合图4对耳机贴合度检测的互斥场景进行说明。
如图4所示，在第一类场景中，假设耳机正在进行以下业务(简称为与耳机贴合度检测互斥的业务)中的一个：播放音乐(即正在进行播放媒体业务)、播放长提示音(即正在进行播放长提示音业务)、通话(即正在进行通话业务)、唤醒语音助手(即正在进行唤醒语音助手业务)等。如果此时耳机开启耳机贴合度检测功能，由于播放媒体业务、播放长提示音业务等会播放音频，通话业务、唤醒语音助手业务会因为需要采集语音并降低噪音而改变耳机的降噪参数，所以都会造成耳机贴合度检测的准确性降低。
如图4所示，在第二类场景中，假设耳机正在进行耳机贴合度检测，如果此时耳机启动以下业务(简称为与耳机贴合度检测互斥的业务)中的一个：播放音乐(即正在进行播放媒体业务)、播放长提示音(即正在进行播放长提示音业务)、通话(即正在进行通话业务)、唤醒语音助手(即正在进行唤醒语音助手业务)等。由于播放媒体业务、播放长提示音业务等会播放音频，通话业务、唤醒语音助手业务会因为需要采集语音并降低噪音而改变耳机的降噪参数，所以都会造成耳机贴合度检测的准确性降低。
需要说明的是，本申请涉及的播放长提示音包括但不限于播放来电提示音、播放去电提示音、播放文字转语音(text to speech，TTS)音频(例如播报体温的TTS音频)、播放自定义音频等等。
针对上述问题，一种处理方式是，当进行与耳机贴合度检测互斥的业务时，由电子设备(例如手机)中的耳机应用(application，APP)来进行决策，例如当电子设备中的音乐应用控制耳机播放音乐时，用户操作耳机应用以进行耳机贴合度检测，则由耳机应用控制音乐应用暂停播放音乐、降低音乐音量或将音乐音量调至无声，耳机应用向耳机传输用于耳机贴合度检测的音频，耳机完成耳机贴合度检测后，耳机应用再控制音乐应用恢复播放音乐或者将音乐音量恢复至原来音量。
采用上述处理方式存在以下缺点：
一方面，对于电子设备的某些操作系统来说，开放给耳机应用的权限较大，可以按照上述方式控制音乐应用来处理上述互斥场景；而对另一些操作系统来说，开放给耳机应用的权限有限，不支持耳机应用控制音乐应用，无法处理上述互斥场景，造成同一种耳机连接采用不同操作系统的电子设备后，对同一种互斥场景的处理方式不同，给用户造成困扰。
另一方面，对于降低音乐音量来说，虽然降低了音乐音量但仍对耳机贴合度检测所需的音频有干扰，可能存在检测结果不准确的问题；还会出现音乐音频和耳机贴合 度检测的预置音频同时播放导致混音问题；暂停播放音乐或将音乐音量调至无声，直至音乐音量耳机完成耳机贴合度检测后，再恢复播放音乐至原来音量，还会造成音乐时有时无的问题，影响用户体验；降低音乐音量，直至音乐音量耳机完成耳机贴合度检测后，再恢复播放音乐至原来音量，还会造成音乐时大时小的问题，同样影响用户体验。
在本申请实施例提供的耳机贴合度检测方法中，由耳机来对耳机贴合度检测的互斥场景进行处理，降低耳机贴合度检测的优先级，当耳机检测到正在进行的业务与耳机贴合度检测互斥时，禁止耳机贴合度检测，或者，当耳机进行耳机贴合度检测还要进行与耳机贴合度检测互斥的业务时，中断耳机贴合度检测。由于是耳机对耳机贴合度检测的互斥场景进行处理，并不依赖于操作系统向耳机应用开放的权限，所以可以兼容多种操作系统，提高了耳机贴合度检测功能的兼容性。并且，由于不会中断或影响当前正在处理的与耳机贴合度检测互斥的业务，因此不会影响用户体验。
针对图4所示的第一类场景，即耳机已经在进行第一业务(关于第一业务见步骤S201中描述)，然后电子设备指示耳机进行耳机贴合度检测，耳机确定正在进行的第一业务与耳机贴合度检测互斥，则耳机禁止耳机贴合度检测(即不启动耳机贴合度检测)，并向电子设备发送第一错误指示信息，以指示耳机禁止进行耳机贴合度检测。具体的，如图5所示，该耳机贴合度检测方法包括：
S201、电子设备向耳机发送业务启动命令。
电子设备中的第一应用向耳机发送业务启动命令，相应地，耳机从电子设备中的第一应用接收业务启动命令。在双耳模式下，电子设备中的第一应用可以向主耳机和副耳机分别发送业务启动命令，即图5中的耳机可以为主耳机或副耳机；或者，如图6中的S201a和S201b所示，在双耳模式下，电子设备中的第一应用向主耳机发送业务启动命令，主耳机将接收的业务启动命令转发给副耳机。
第一应用指除了耳机应用以外的应用，例如音乐播放器、电话软件、语音助手、视频软件等。耳机应用指与耳机配套使用的应用，可以实现对耳机进行配置(例如，配置耳机贴合度检测参数(例如降噪参数)、进行耳机贴合度检测等)、对耳机进行在线升级等。
业务启动命令用于指示耳机启动第一业务，其中，第一业务指：改变耳机的降噪参数的业务，或者，播放除了耳机贴合度检测所需音频之外的其他音频的业务。其中，耳机贴合度检测所需音频指前文所述的预置音频，预置音频随耳机出厂时预先存储在耳机中。
如前文所述的，改变耳机的降噪参数的业务可以包括以下业务中的至少一项：唤醒语音助手业务、通话业务等。电子设备通过语音传输通道来与耳机传输这些业务的音频数据，示例性的，语音传输通道可以为SCO通道。这些业务需要采集语音并降低噪音，因此会改变耳机的降噪参数，根据前文所述的耳机贴合度检测的原理，进行耳机贴合度检测时，耳机会根据预设的耳机贴合度检测参数(例如降噪参数)来播放预置音频，所以这些业务都会造成耳机贴合度检测的准确性降低。
播放除了耳机贴合度检测所需音频之外的其他音频的业务可以包括以下业务中的至少一项：播放媒体业务(例如播放音乐)、播放长提示音业务(例如播放来电提示 音、去电提示音、TTS音频、自定义音频等)。电子设备通过音频传输通道来与耳机传输这些业务的音频数据，示例性的，音频传输通道可以为A2DP通道。这些业务会播放除了预置音频以外的音频，根据前文所述的耳机贴合度检测的原理，进行耳机贴合度检测时，耳机会根据预设的耳机贴合度检测参数(例如降噪参数)来播放预置音频，所以这些业务播放的音频会与预置音频混音，因此会造成耳机贴合度检测的准确性降低。
具体的，业务启动命令可以为语音传输通道(例如SCO通道)的状态切换命令，语音传输通道(例如SCO通道)的状态切换命令指示耳机将语音传输通道(例如SCO通道)从空闲状态切换至连接状态，以此来指示耳机启动第一业务(例如唤醒语音助手业务、通话业务)。语音传输通道在连接状态时被占用，在空闲状态时不被占用。或者，业务启动命令可以为音频传输通道(例如A2DP通道)的状态切换命令，音频传输通道(例如A2DP通道)的状态切换命令指示耳机将音频传输通道(例如A2DP通道)从空闲状态切换至播放状态或暂停状态，以此来指示耳机启动第一业务(例如播放媒体业务、播放长提示音业务)。耳机的音频传输通道在空闲状态时停止播放音频，在播放状态时播放音频，在暂停状态时暂停播放音频。音频传输通道在播放状态或暂停状态时被占用，在空闲状态时不被占用。
以电子设备为手机为例，电子设备向耳机发送业务启动命令的触发条件包括但不限于：示例性的，如图7中A所示，用户点击音乐播放器(即前文所述的第一应用)中的音乐播放按钮S，此时会触发音乐播放器通过耳机播放音乐(即触发播放媒体业务)；用户通过电子设备中的测温应用触发耳机播放测温TTS音频(即触发播放长提示音业务)用户点击拨号按钮以进行呼叫，此时会触发耳机播放去电提示音(即触发播放长提示音业务)；电子设备被呼叫，此时会触发耳机播放来电提示音(即触发播放长提示音业务)；用户点击接听按钮以进行通话，此时会触发耳机传输语音(即触发通话业务)；用户对电子设备说出关键词以唤醒语音助手，此时会触发耳机与电子设备传输语音助手相关音频(即触发唤醒语音助手业务)等等。
S202、耳机启动第一业务。
如图6中的S202a和S202b所示，在双耳模式下，主耳机和副耳机分别启动第一业务。具体的，主耳机和副耳机会将蓝牙驱动层接收到的业务启动命令传递至各自的应用层，由应用层启动第一业务。其中，耳机的蓝牙驱动层用于实现耳机与电子设备之间的蓝牙通信，例如传输命令、音频数据、语音数据等；应用层用于启动第一业务、进行耳机贴合度检测等。
假设业务启动命令为语音传输通道(例如SCO通道)的状态切换命令，语音传输通道(例如SCO通道)的状态切换命令指示耳机将语音传输通道(例如SCO通道)从空闲状态切换至连接状态，则耳机的应用层将语音传输通道(例如SCO通道)从空闲状态切换至连接状态，并启动第一业务，例如，对于启动唤醒语音助手业务或通话业务来说，耳机中的扬声器播放来自电子设备的音频，并将通过麦克风采集的环境音发送给电子设备。
或者，假设业务启动命令为音频传输通道(例如A2DP通道)的状态切换命令，音频传输通道(例如A2DP通道)的状态切换命令指示耳机将音频传输通道(例如A2DP 通道)从空闲状态切换至播放状态或暂停状态，则耳机的应用层将音频传输通道(例如A2DP通道)从空闲状态切换至播放状态或暂停状态，并启动第一业务，例如，对于启动播放媒体业务或播放长提示音业务，耳机中的扬声器播放来自电子设备的音频。
耳机启动第一业务后可以向电子设备中的第一应用发送启动指示信息，以指示已启动第一业务。此时，第一应用可以显示提示信息，以指示用户当前耳机正在运行第一业务。示例性的，如图7中B所示，电子设备中的音乐播放器可以显示界面“正在播放XXXXX”，以提示用户正在通过耳机播放音乐。
S203、电子设备向耳机发送贴合度检测命令。
电子设备中的耳机应用向耳机发送贴合度检测命令，相应地，耳机从电子设备中的耳机应用接收贴合度检测命令。在双耳模式下，电子设备中的耳机应用可以向主耳机和副耳机分别发送贴合度检测命令，即图5中的耳机可以为主耳机或副耳机；或者，如图6中的S203a和S203b所示，在双耳模式下，电子设备中的耳机应用向主耳机发送贴合度检测命令，主耳机将接收的贴合度检测命令转发给副耳机。贴合度检测命令用于指示耳机进行耳机贴合度检测。
示例性的，如图8中A所示，以电子设备为手机为例，电子设备向耳机发送贴合度检测命令的触发条件可以包括但不限于：电子设备中的耳机应用显示“耳机贴合度检测”界面，用户点击耳机贴合度检测按钮T。如图8中B所示，在非互斥场景下，在耳机进行耳机贴合度检测过程中，电子设备中的耳机应用显示“耳机贴合度检测中请稍候...”，如果此时用户点击耳机贴合度检测按钮T则可以停止耳机贴合度检测。耳机完成耳机贴合度检测后可以向电子设备中的耳机应用发送检测结果，以指示已完成耳机贴合度检测以及各个耳机的贴合度。此时，耳机应用可以显示提示信息，以指示用户已经完成耳机贴合度检测以及各个耳机的贴合度。示例性的，如图8中C所示，经过耳机完成耳机贴合度检测之后，如果某个耳机的贴合度良好，则电子设备中的耳机应用可以显示“贴合度良好”(例如图8中右耳机R)，如果某个耳机的贴合度较差，则电子设备中的耳机应用可以显示“请重新调整”(例如图8中左耳机L)；如果用户重新调整耳机后，可以点击耳机贴合度检测按钮T以重新进行耳机贴合度检测。
示例性的，如图9中A所示，在互斥场景下，假设电子设备中的音乐播放器正在通过耳机播放音乐，此时，如图9中B所示，用户切换至耳机应用，用户点击耳机贴合度检测按钮T，则电子设备向耳机发送贴合度检测命令。
S204、耳机确定正在进行的第一业务与耳机贴合度检测是否互斥。
或者说，耳机确定是否正在进行与耳机贴合度检测互斥的业务。如图6中的S204a和S204b所示，在双耳模式下，主耳机和副耳机均需要确定自身正在进行的第一业务是否与耳机贴合度检测互斥。具体的，主耳机和副耳机会将蓝牙驱动层接收到的贴合度检测命令传递至各自的应用层，由应用层确定正在进行的第一业务是否与耳机贴合度检测互斥。
耳机的应用层可以通过确定耳机的语音传输通道(例如SCO通道)处于连接状态，来确定正在进行的第一业务(例如唤醒语音助手业务、通话业务)与耳机贴合度检测互斥。或者，耳机的应用层可以通过确定耳机的音频传输通道(例如A2DP通道)处于播放状态或暂停状态，来确定正在进行的第一业务(例如播放媒体业务、播放长提 示音业务)与耳机贴合度检测互斥。
当耳机的语音传输通道处于连接状态时，表明电子设备正在通过耳机的语音传输通道与耳机传输通话业务或唤醒语音助手业务的音频数据。当耳机的音频传输通道处于播放状态或暂停状态时，表明电子设备正在通过耳机的音频传输通道与耳机传输播放媒体业务或播放长提示音业务的音频数据。
耳机的应用层可以通过确定耳机的语音传输通道(例如SCO通道)处于断开状态，并且，耳机的音频传输通道(例如A2DP通道)处于空闲状态，来确定正在进行的第一业务与耳机贴合度检测不互斥。
S205、如果耳机确定正在进行的第一业务与耳机贴合度检测互斥，则禁止进行耳机贴合度检测。
如图6中的S205a和S205b所示，在双耳模式下，主耳机和副耳机均需要禁止自身进行耳机贴合度检测。此时，耳机不会通过扬声器播放预置音频，不会通过麦克风进行收音，也不会通过处理器进行耳机贴合度检测。
S206、耳机向电子设备发送第一错误指示信息。
耳机向电子设备中的耳机应用发送第一错误指示信息，相应地，电子设备中的耳机应用从耳机接收第一错误指示信息。在双耳模式下，主耳机和副耳机可以分别向电子设备发送各自的第一错误指示信息，即图5中的耳机可以为主耳机或副耳机；或者，如图6中的S206a和S206b所示，在双耳模式下，副耳机通过主耳机向电子设备发送副耳机的第一错误指示信息，即副耳机向主耳机发送副耳机的第一错误指示信息，主耳机向电子设备中的耳机应用发送主耳机的第一错误指示信息以及副耳机的第一错误指示信息。主耳机的第一错误指示信息以及副耳机的第一错误指示信息可以位于一条消息中或者位于不同消息中。
第一错误指示信息用于指示耳机禁止进行耳机贴合度检测，主耳机的第一错误指示信息用于指示主耳机禁止进行耳机贴合度检测，副耳机的第一错误指示信息用于指示副耳机禁止进行耳机贴合度检测。第一错误指示信息可以采用错误码的形式，并且主耳机的第一错误指示信息和副耳机的第一错误指示信息所采用的错误码不同，例如可以用二进制数00表示主耳机的第一错误指示信息，用二进制数01表示副耳机的第一错误指示信息。
S207、电子设备显示第一提示信息。
电子设备接收到来自耳机的第一错误指示信息之后，可以在显示屏显示第一提示信息，在双耳模式下，电子设备只要接收到主耳机的第一错误指示信息或副耳机的第一错误指示信息中的至少一个，都可以在显示屏显示第一提示信息。第一提示信息用于提示用户只有停止正在进行的与耳机贴合度检测互斥的第一业务，才可启动耳机贴合度检测。示例性的，如图9中C所示，电子设备的耳机应用可以显示“无法执行耳机贴合度检测，当前耳机被占用”，以提示用户，如果要进行耳机贴合度检测，则需要停止正在进行的与耳机贴合度检测互斥的第一业务，以避免降低耳机贴合度检测的准确性。
本申请实施例提供的上述耳机贴合度检测方法，耳机已经在进行第一业务，第一业务可以改变耳机的降噪参数的业务，或者，播放除了耳机贴合度检测所需音频之外 的其他音频，会导致耳机贴合度检测的准确性降低。此时，如果耳机接收到贴合度检测命令(贴合度检测命令用于指示耳机进行耳机贴合度检测)，则耳机禁止耳机贴合度检测(即不启动耳机贴合度检测)。因此，由耳机执行控制逻辑，通过降低耳机贴合度检测的优先级，来避免与第一业务冲突，不会依赖电子设备中操作系统开放给耳机应用的权限，对于采用不同操作系统的电子设备来说，耳机对互斥场景的处理是一致的，因此可以提高耳机贴合度检测的兼容性。可选的，耳机还可以向电子设备发送第一错误指示信息，以指示耳机禁止进行耳机贴合度检测，方便电子设备提醒用户。
针对图4所示的第二类场景，即耳机已经在进行耳机贴合度检测，然后电子设备指示耳机进行与耳机贴合度检测互斥的第一业务，则耳机中断耳机贴合度检测，并向电子设备发送第二错误指示信息，以指示中断耳机贴合度检测。具体的，如图10所示，该耳机贴合度检测方法包括：
S301、电子设备向耳机发送贴合度检测命令。
电子设备中的耳机应用向耳机发送贴合度检测命令，相应地，耳机从电子设备中的耳机应用接收贴合度检测命令。在双耳模式下，电子设备中的耳机应用可以向主耳机和副耳机分别发送贴合度检测命令，即图10中的耳机可以为主耳机或副耳机；或者，如图11中的S301a和S301b所示，在双耳模式下，电子设备中的耳机应用向主耳机发送贴合度检测命令，主耳机将接收的贴合度检测命令转发给副耳机。
如图12中A所示，电子设备中的耳机应用显示“耳机贴合度检测”界面，用户点击耳机贴合度检测按钮T，电子设备中的耳机应用向耳机发送贴合度检测命令。
步骤S301的其他内容参照步骤S203，在此不再重复。
S302、耳机确定是否正在进行与耳机贴合度检测互斥的第一业务。
如图11中的S302a和S302b所示，在双耳模式下，主耳机和副耳机均需要确定自身是否正在进行与耳机贴合度检测互斥的第一业务。具体的，主耳机和副耳机会将蓝牙驱动层接收到的贴合度检测命令传递至各自的应用层，由应用层确定是否正在进行与耳机贴合度检测互斥的第一业务。
关于第一业务参照步骤S201，在此不再赘述。
耳机的应用层可以通过确定耳机的语音传输通道(例如SCO通道)处于连接状态，来确定正在进行与耳机贴合度检测互斥的第一业务(例如唤醒语音助手业务、通话业务)。或者，耳机的应用层可以通过确定耳机的音频传输通道(例如A2DP通道)处于播放状态或暂停状态，来确定正在进行与耳机贴合度检测互斥的第一业务(例如播放媒体业务、播放长提示音业务)。
当耳机的语音传输通道处于连接状态时，表明电子设备正在通过耳机的语音传输通道与耳机传输通话业务或唤醒语音助手业务的音频数据。当耳机的音频传输通道处于播放状态或暂停状态时，表明电子设备正在通过耳机的音频传输通道与耳机传输播放媒体业务或播放长提示音业务的音频数据。都会降低耳机贴合度检测的准确性。
耳机的应用层可以通过确定耳机的语音传输通道(例如SCO通道)处于断开状态，并且，耳机的音频传输通道(例如A2DP通道)处于空闲状态，来确定耳机未在进行与耳机贴合度检测互斥的第一业务。
当耳机的语音传输通道处于断开状态时，表明电子设备没有在通过耳机的语音传 输通道与耳机传输通话业务或唤醒语音助手业务的音频数据。当耳机的音频传输通道处于空闲状态时，表明电子设备也没有在通过耳机的音频传输通道与耳机传输播放媒体业务或播放长提示音业务的音频数据。因此，不会造成耳机贴合度检测的准确性降低。
S303、如果耳机确定未在进行与耳机贴合度检测互斥的第一业务，则启动耳机贴合度检测。
如图11中的S303a和S303b所示，在双耳模式下，主耳机和副耳机各自确定自身未在进行与耳机贴合度检测互斥的第一业务，并启动耳机贴合度检测。
如前文所述的，在耳机贴合度检测过程中，耳机中的扬声器按照预设的耳机贴合度检测参数(例如降噪参数)播放一段预置音频，耳机中的麦克风(位于耳道外面)对环境音(其中包括了从耳道与耳机之间缝隙泄露的预置音频)进行收音，耳机通过分析播放的预置音频和接收到的泄漏的预置音频来确定预置音频的泄露值，该泄露值越小则用户的耳道与耳机越贴合。
示例性的，如图12中B所示，在耳机进行耳机贴合度检测过程中，电子设备中的耳机应用显示“耳机贴合度检测中请稍候...”，如果此时用户点击耳机贴合度检测按钮T则可以停止耳机贴合度检测。
S304、电子设备向耳机发送业务启动命令。
电子设备中的第一应用向耳机发送业务启动命令，相应地，耳机从电子设备接收业务启动命令。在双耳模式下，电子设备的第一应用可以向主耳机和副耳机分别发送业务启动命令，即图10中的耳机可以为主耳机或副耳机；或者，如图11中的S304a和S304b所示，在双耳模式下，电子设备的第一应用向主耳机发送业务启动命令，主耳机将接收的业务启动命令转发给副耳机。
其中，业务启动命令用于指示耳机启动第一业务。业务启动命令可以为语音传输通道(例如SCO通道)的状态切换命令，语音传输通道(例如SCO通道)的状态切换命令指示耳机将语音传输通道(例如SCO通道)从空闲状态切换至连接状态，以此来指示耳机启动第一业务(例如唤醒语音助手业务、通话业务)。或者，业务启动命令可以为音频传输通道(例如A2DP通道)的状态切换命令，音频传输通道(例如A2DP通道)的状态切换命令指示耳机将音频传输通道(例如A2DP通道)从空闲状态切换至播放状态或暂停状态，以此来指示耳机启动第一业务(例如播放媒体业务、播放长提示音业务)。
示例性的，如图12中B和C所示，假设在耳机进行耳机贴合度检测过程中，用户切换至音乐播放器(即前文所述的第一应用)，并点击播放按钮S，则音乐播放器向耳机发送业务启动命令，以指示耳机播放音乐。
步骤S304的其他内容参照步骤S201，在此不再重复。
S305、在完成耳机贴合度检测之前，如果耳机从电子设备接收到业务启动命令，则中断耳机贴合度检测并启动第一业务。
如图11中的S305a和S305b所示，在双耳模式下，主耳机和和副耳机各自中断耳机贴合度检测并启动与耳机贴合度检测互斥的第一业务。具体的，主耳机和副耳机会将蓝牙驱动层接收到的业务启动命令传递至各自的应用层，由应用层中断耳机贴合度 检测并启动与耳机贴合度检测互斥的第一业务。
耳机完成耳机贴合度检测之前可以指：耳机正在通过扬声器播放预置音频，并通过扬声器播放预置音频，以及，通过处理器进行耳机贴合度检测。耳机中断耳机贴合度检测可以指：耳机停止通过扬声器播放预置音频，停止通过麦克风进行收音，并且停止通过处理器进行耳机贴合度检测。
耳机启动第一业务后可以向电子设备中的第一应用发送启动指示信息，以指示已启动第一业务。此时，第一应用可以显示提示信息，以指示用户当前耳机正在运行第一业务。示例性的，如图12中D所示，电子设备中的音乐播放器可以显示界面“正在播放XXXXX”，以提示用户正在通过耳机播放音乐。
步骤S305的其他内容参照步骤S202，在此不再重复。
S306、耳机向电子设备发送第二错误指示信息。
耳机向电子设备中的耳机应用发送第二错误指示信息，相应地，电子设备中的耳机应用从耳机接收第二错误指示信息。在双耳模式下，主耳机和副耳机可以分别向电子设备中的耳机应用发送各自的第二错误指示信息，即图10中的耳机可以为主耳机或副耳机；或者，如图11中的S306a和S306b所示，在双耳模式下，副耳机通过主耳机向电子设备发送副耳机的第二错误指示信息，即副耳机向主耳机发送副耳机的第二错误指示信息，主耳机向电子设备中的耳机应用发送主耳机的第二错误指示信息以及副耳机的第二错误指示信息。主耳机的第二错误指示信息以及副耳机的第二错误指示信息可以位于一条消息中或者位于不同消息中。
第二错误指示信息用于指示耳机中断耳机贴合度检测，主耳机的第二错误指示信息用于指示主耳机中断耳机贴合度检测，副耳机的第二错误指示信息用于指示副耳机中断耳机贴合度检测。第二错误指示信息可以采用错误码的形式，并且主耳机的第二错误指示信息和副耳机的第二错误指示信息所采用的错误码不同，例如可以用二进制数10表示主耳机的第二错误指示信息，用二进制数11表示副耳机的第二错误指示信息。
S307、电子设备显示第二提示信息。
电子设备接收到来自耳机的第二错误指示信息之后，可以在显示屏显示第二提示信息，在双耳模式下，电子设备只要接收到主耳机的第二错误指示信息以及副耳机的第二错误指示信息中的至少一个，都可以在显示屏显示第二提示信息。第二提示信息用于提示用户耳机已中断耳机贴合度检测。示例性的，如图12中E所示，如果用户从音乐播放器切换回耳机应用，则电子设备的耳机应用可以显示“耳机贴合度检测已中断，当前耳机被占用”，以提示用户耳机已经因为正在进行的第一业务而中断耳机贴合度检测。
本申请实施例提供的上述耳机贴合度检测方法，当耳机已经在进行耳机贴合度检测时，如果接收到指示耳机进行与耳机贴合度检测互斥的第一业务的命令，则耳机中断耳机贴合度检测。与耳机贴合度检测互斥的第一业务可能改变耳机的降噪参数，或者，播放除了耳机贴合度检测所需音频之外的其他音频，导致耳机贴合度检测的准确性降低。因此，由耳机执行控制逻辑，通过降低耳机贴合度检测的优先级，来避免与第一业务冲突，不会依赖电子设备中操作系统开放给耳机应用的权限，对于采用不同 操作系统的电子设备来说，耳机对互斥场景的处理是一致的，因此可以提高耳机贴合度检测的兼容性。可选的，耳机还可以向电子设备发送第二错误指示信息，以指示耳机中断耳机贴合度检测，方便电子设备提醒用户。
如图13所示，本申请实施例还提供一种芯片系统。该芯片系统60包括至少一个处理器601和至少一个接口电路602。至少一个处理器601和至少一个接口电路602可通过线路互联。处理器601用于支持耳机实现上述方法实施例中的各个步骤，例如图5、图6、图10、图11所示的方法，至少一个接口电路602可用于从其它装置(例如存储器)接收信号，或者，向其它装置(例如通信接口)发送信号。该芯片系统可以包括芯片，还可以包括其他分立器件。
