还应当理解，在本申请说明书和所附权利要求书中使用的术语“和/或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合，并且包括这些组合。

另外，在本申请说明书和所附权利要求书的描述中，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
在本申请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。
图1示出了一种通过无线耳机通话时的场景，其中包括：无线耳机11、终端设备12。无线耳机11通常可以为蓝牙耳机，如头戴式蓝牙耳机、颈带式蓝牙耳机、耳塞式蓝牙耳机、耳挂式蓝牙耳机。或者，还可以是TWS耳机。
而终端设备则为支持与无线耳机连接并通话的设备，如智能手机、平板电脑、笔记本电脑、具有无线模块的台式电脑等，在此不做限制。
在图1示出的场景中，终端设备12与另一通话设备通信连接，进行通话。无线耳机11通过蓝牙与终端设备12通信连接，无线耳机11接收用户发出的音频信息，并对音频信息进行处理。然后通过蓝牙协议，如蓝牙免提规范(Hands-free Profile，HFP)蓝牙耳机规范(Headset Profile，HSP)或高级音频传输规范(Advanced Audio Distribution Profile,A2DP)等，将处理后的音频信息发送给终端设备。终端设备再通过蜂窝网络将音频信息发送给与其通信连接的通话设备，并接受与其通信连接的通话设备发送的音频信息。其中，蜂窝网络包括但不限于全球移动通讯系统(Global System of Mobile communication，GSM)、通用分组无线服务(General Packet Radio Service，GPRS)、码分多址(Code Division Multiple Access，CDMA)、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)、长期演进(Long Term Evolution，LTE)、时分复用WCDMA(Time-Division WCDMA，TD-WCDMA)、时分复用LTE(Time-Division LTE，TD-LTE)、第五代新无线(the 5th generation New Radio，5G NR)等。
需要说明的是，静音操作可以包括对麦克风静音的操作、对某一个应用程序的静音操作、或者对整个终端设备的静音操作。终端设备静音后，不再向与其通信连接的通话设备发送音频数据。
通过无线耳机进行通话可以是通过无线耳机打电话。或者，也可以是通过无线耳机在应用程序中进行语音通话。再或者，还可以在通过终端设备进行视频通话时的语音通话部分。在此对通话的类型不做限制。
例如，若静音操作为对麦克风静音的操作，则当接收到作用于麦克风静音按键121的点击操作时终端设备12将停止向与其通信连接的通话设备发送音频数据。
目前的无线耳机在终端设备静音时，并未采取相应的低功耗措施，依然在采集用户的音频数据并处理上传。但是，这种情况下实际上是无需进行音频数据采集的。在静音时持续上传音频数据，会导致无线耳机在无需进行音频数据采集时，仍然在采集音频数据，浪费功耗，降低续航。
为此，本申请提供了一种无线耳机的低功耗方法，以降低无线耳机的功耗，提高续航。
图2示出了一种可以应用本申请提供的无线耳机低功耗方法的无线耳机的结构示 意图。
参考图2，该无线耳机包括：蓝牙核心模块(Bluetooth core，BT core)21、数字信号处理模块(Digital Signal Process，DSP)22、编码译码模块(Codec)23、发声单元(Speaker)24、收音单元(Mic)25、控制单元26。
一些实施方式中，BT core能够实现蓝牙功能，如进行蓝牙配对、蓝牙连接，并通过蓝牙发送和接收消息等。例如，BT Core可以通过移动宽带(Mobile Broadband，MBB)、蓝牙低能耗(Bluetooth Low Energy，BLE)、串行端口规范(Serial Port Profile，SPP)、面向连接的同步链路(Synchronous Connection Oriented link，SCO)等协议，建立与终端设备之间的通信链路，并通过通信链路下行数据(如从终端设备下载至无线耳机处理的数据)、上行数据(上传至终端设备，发送给通话设备的数据)以及收发控制数据(如状态相关信息)等。
而DPS模块，则可以在上行数据和下行数据时，通过相关算法对数据进行处理。例如，上行数据时的相关算法，包括多麦克风(Mic)数据预处理、上行降噪算法、数据转换重采样、音频编码等。下行数据时的相关算法，则包括双耳同步算法、音频解码、数据转换重采样、下行降噪、增益(Gain)值调节、校准值应用、混音算法等。
Codec模块，则用于通过收音单元采集音频数据。其中，收音单元内包括多个Mic，如，前反馈麦克风(Feed Forward Mic，FF Mic)、后反馈麦克风(Feed Back Mic，FB Mic)、主麦克风(Main Mic)、音频输入麦克风(Auxiliary Mic，Aux Mic)。在采集到音频数据后，Codec模块还可以通过模数转换器(ADC)，将采集到的模拟音频数据转换为数字音频数据，并传递给DPS模块，进行处理。
Codec模块，还可以将DPS发送来的数字音频数据通过数模转换器(DAC)转换为模拟音频数据，并发送给放音单元(Speaker)，对音频数据进行播放。
最后，Codec模块还可以用于管理多个Mic的上电与下电，即Codec模块可以关闭放音单元中的任意一个麦克风。
控制单元则可以接收用户的操作。作为示例，控制单元可以是触控的，和/或控制单元还可以为按键控制的。例如，当控制单元为触控时，若接收到预设的触控操作，如双击操作、点击操作、滑动操作等，则可以控制无线耳机进行相应的动作。或者，当控制单元为按键控制时，若接收到作用于预设按键的按压操作，则可以控制无线耳机进行相应的动作。
图3示出了本申请提供的一种无线耳机的低功耗方法的示意性流程图，作为示例而非限定，该方法可以应用于上述无线耳机中，无线耳机与终端设备通信连接。
S31、在通过无线耳机进行通话时，检测是否接收到静音操作。
一些实施方式中，在进行通话时，可能会出现需要静音的情况。在这个情况下，用户往往会在无线耳机或终端设备上进行静音的操作。例如，参考图1，静音操作可以是终端设备接收到作用于麦克风静音按键121的点击操作、或者是接收到作用于静音按键的点击操作、或者作用于触摸屏上的预设手势等。
一些实施方式中，参考图4和图5，静音操作还可以是无线耳机11上触控区域111接收到的双击操作、敲击操作或滑动操作。或者，若无线耳机11上设置有物理按键，则静音操作还可以是无线耳机11接收到作用于物理按键的按压操作等，在此不做 限制。再或者，若无线耳机11上设置有传感器，则静音操作还可以是传感器检测到相应的传感信号，如光线传感器检测到光线被遮挡、接近光传感器检测到无线耳机远离人耳等。
S32、若检测到静音操作，则响应静音操作，将无线耳机切换至低功耗模式。
一些实施方式中，检测到静音操作，即说明用户暂时不使用麦克风。这个情况下，可以将无线耳机切换至低功耗模式，以减少无线耳机的功耗。
其中，在切换至低功耗模式时，执行以下低功耗操作中的至少一种：降低无线耳机中至少一个麦克风的音频采集频率、关闭无线耳机中至少一个麦克风、关闭无线耳机中的至少一种上行数据处理算法。
作为示例，一般麦克风在采集音频时，采集频率为44100Hz或48000Hz，有时为了采集到音频质量更高的音频数据，采集频率还可以为96000Hz或192000Hz等。由于无线耳机中存在多个麦克风，如用于进行采集用于降噪音频数据的FF Mic和FB Mic，用于采集用户发出的音频数据的Main Mic等。在进入低功耗模式时，可以将其中至少一个麦克风的采集频率降至44100Hz，甚至更低，如22050Hz、11025Hz等，在此不做限制。
或者，也可以直接关闭无需使用的麦克风，例如，在检测到静音操作操作后，无线耳机无需采集用户发出的音频，可以将Main Mic下电以降低功耗。甚至可以将所有麦克风均下电，以更加彻底的降低功耗。
再一种示例中，无论麦克风降频或关闭，DSP仍在对上行的音频数据通过算法进行处理。此时，由于上行数据时无用的，所以可以关闭其中至少一种上行处理算法，如关闭多麦克风(Mic)数据预处理、上行降噪算法等算法，暂停对上行数据的优化处理，以减少功耗。
在本实施例中，通过无线耳机进行通话时，若检测到静音操作，则响应静音操作，对无线耳机进行低功耗处理，低功耗处理包括以下操作中的至少一种：降低无线耳机中至少一个麦克风的音频采集频率、关闭无线耳机中至少一个麦克风、关闭无线耳机中的至少一种上行数据处理算法。通过在通话时检测静音操作，若静音，则执行低功耗策略，降低无线耳机在通话时的功耗，提升了无线耳机的续航时间。
图6示出了一种无线耳机低功耗方法可能的流程示意图。
参考图6，该方法包括：
S41、判断终端设备是否检测到静音操作，若检测到，则执行S42，否则继续检测。
一些实施方式中，终端设备接收到的静音操作，可以参考图1，检测到作用于麦克风静音按键121的点击操作。或者，是检测到作用于机身上预设的虚拟按键区域或物理按键区域的按压操作。例如，检测到拨动或点击用于静音的物理按键，或者检测到双击“音量-”按键，再或者检测到同时按压“音量+”和“音量-”按键等。其中，“音量+”和“音量-”按键，即可以是物理按键，也可以是虚拟按键。当其为物理按键时，可以检测物理按键下压后发出的电信号，以确定接收到静音操作。而其作为虚拟按键时，则可以检测作用于虚拟按键展示区域的点击操作或按压操作，以确定接收到静音操作。再或者，静音操作还可以是预设的手势，如检测到在屏幕上的滑动操作形成了“q”型的轨迹等，在此不做限制。
S42、终端设备向无线耳机发送静音指令，执行S43和S44。
一些实施方式中，静音指令可以为终端设备切换为静音状态的状态信息。在发送状态信息时，可以通过以下链路中的一种进行发送：BLE、SPP、SCO或A2DP等。或者，也可以通过其他链路进行发送，如MBB，本申请对发送状态信息的链路不做限制。
S43、无线耳机切换至低功耗模式，并执行以下低功耗操作中的至少一种：降低无线耳机中至少一个麦克风的音频采集频率、关闭无线耳机中至少一个麦克风、关闭无线耳机中的至少一种上行数据处理算法。
一些实施方式中，参考S32在无线耳机切换至低功耗模式后，可以先降低麦克风的功耗。作为示例，若无线耳机为TWS耳机，则包括两个耳机，一个为主耳，一个为副耳，主耳为与终端设备直接连接的耳机，副耳为与主耳连接的耳机。其中，主耳的麦克风用于采集音频数据。则可以降低主耳的麦克风功耗。一般来说，Main Mic用于拾取用户的音频数据，而其他麦克风(副mic)则用于为声学回声消除(Acoustic Echo Cancelling，AEC)、自动增益控制(Automatic Gain Control，AGC)、主动降噪(Active Noise Control，ANC)等算法(3A算法)提供数据输入。所以，可以将Main Mic下电，降低其余副Mic的采集频率。或者，将主Mic和各Mic同时下电，更加彻底降低主耳的功耗。在本申请中，对哪几个Mic进行下电，对哪几个Mic进行降频，不做限制。
降低主耳的功耗，可以减少主副耳之间电量差的增加速度，增加主耳续航。在仅使用单耳机时，亦可增加单耳机的续航时间。
另一些实施方式中，在降低麦克风的功耗之后，还可以关闭上行数据的相关算法，例如，3A上行降噪算法、音频重采样算法、混音合成算法等，以进一步降低无线耳机的功耗。
同时，由于关闭了多个上行数据的算法，对DSP的数据处理能力要求也响应降低了，所以，在关闭上行数据的相关算法后，还可以降低DSP的主频，降低DSP的功耗，进而降低无线耳机的功耗。
相应的，在Mic下电后，Mic不再采集音频数据，则Codec可以关闭对Mic进行处理的通路，以更加有效的降低无线耳机的功耗。
S44、终端设备展示静音的提示信息，执行S45。
一些实施方式中，若静音操作为麦克风静音，则终端设备可以改变图1所示的麦克风静音按键121的颜色、形状等。或者，还可以在通知栏中展示静音的标识和文字，以提示用户终端设备当前已静音。本申请对提示静音的方式不做限制。
S45、判断终端设备是否检测到取消静音的操作，若检测到，则执行S46，否则继续检测。
一些实施方中，在终端设备已经被设置为静音时，若检测到S41中示出的静音操作，则可以确认检测到取消静音的操作。即在终端设备已经被设置为静音时，可以将静音操作为取消静音的操作。
S46、终端设备向无线耳机发送取消静音的指令，执行S47和S48。
其中，终端设备向无线耳机发送取消静音的指令与S42中类似，在此不做赘述。
S47、无线耳机关闭低功耗模式。
一些实施方式中，无线耳机关闭低功耗模式时，可执行与S43中相反的操作。例如，若关闭了Mic，则可以将关闭的Mic打开。若关闭了主耳的3A上行算法，则可以恢复主耳的3A上行算法。需要说明的是，在打开Mic和上行算法时，可能会由于音频器件进行上电以及上电稳定后，各种算法处理音频数据时带来的瞬态冲击所产生的爆破声(Pop音)，为此，可以在关闭耳机低功耗模式时，使用淡入淡出的均衡器(EQ)设置，以防止产生Pop音。
S48、终端设备展示静音取消的提示信息。
其中，展示静音取消的提示信息，可以参考S44，在此不做赘述。
图7示出了另一种无线耳机低功耗方法可能的流程示意图。
参考图7，该方法包括：
S51、判断无线耳机是否检测到静音操作，若检测到，则执行S52，否则继续检测。
一些实施方式中，参考图4和图5，检测无线耳机上的静音操作，包括但不限于检测到作用于触控区域111的预设动作。预设动作可以包括双击、滑动、敲击、按压等。或者，若无线耳机上存在物理按键，检测无线耳机上的静音操作还可以是检测到作用于物理按键的点击操作，产生的电信号。再或者，若无线耳机上还设置有传感器，则在传感器检测到相应的操作时，可以确定为检测到静音操作。如无线耳机上存在光传感器，则可以在光传感器检测到光线被遮挡时，确定检测到静音操作。如无线耳机上存在接近光传感器，则可以在接近光传感器检测到无线耳机远离人耳时，确定检测到静音操作。
S52、无线耳机向终端设备无线耳机发送静音指令，执行S53和S54。
其中，无线耳机向终端设备无线耳机发送静音指令，与S42中类似，在此不做赘述。
S53、无线耳机切换至低功耗模式，并执行以下低功耗操作中的至少一种：降低无线耳机中至少一个麦克风的音频采集频率、关闭无线耳机中至少一个麦克风、关闭无线耳机中的至少一种上行数据处理算法，执行S55。
其中，无线耳机切换至低功耗模式，与S43中类似，在此亦不做赘述。
S54、终端设备响应静音指令，展示静音的提示信息。
一些实施方式中，终端设备接受到的静音指令，包括指示将终端设备切换为静音状态的指令。终端设备在接收到该指令后，根据该指令切换为静音状态，并如S44所示的方式，展示静音的提示信息。
S55、判断无线耳机是否检测到取消静音操作，若检测到，则执行S56，否则继续检测。
一些实施方式中，参考S45，在无线耳机已经被设置为静音时，若检测到S51中示出的静音操作，则可以确认检测到取消静音的操作。即在无线耳机已经被设置为静音时，可以将静音操作为取消静音的操作。
S56、无线耳机向终端设备发送取消静音的指令，执行S57和S58。
其中，终端设备向无线耳机发送取消静音的指令与S52中类似，在此不做赘述。
S57、无线耳机关闭低功耗模式。
一些实施方式中，参考S47，无线耳机关闭低功耗模式时，可执行与S53中相反的操作。例如，若关闭了Mic，则可以将关闭的Mic打开。若关闭了主耳的3A上行算法，则可以恢复主耳的3A上行算法。需要说明的是，在打开Mic和上行算法时，可能会由于音频器件进行上电以及上电稳定后，各种算法处理音频数据时带来的瞬态冲击所产生的爆破声(Pop音)，为此，可以在关闭耳机低功耗模式时，使用淡入淡出的均衡器(EQ)设置，以防止产生Pop音。
S58、终端设备取消响应静音的指令，展示静音取消的提示信息。
其中，展示静音取消的提示信息，可以参考S54，在此不做赘述。
应理解，上述实施例中各步骤的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
