本申请实施例涉及电子技术领域，尤其涉及一种头戴式无线耳机。The embodiment of the present application relates to the field of electronic technology, and in particular to a wireless headphone.
背景技术Background technique
头戴式无线耳机可以摆脱与终端设备(比如手机，笔记本电脑，平板电脑等)的连接线的限制，并且头戴式无线耳机具有较好的声场及佩戴舒适度，因此成为各类音乐爱好者欣赏音乐的首选设备。Head-mounted wireless earphones can get rid of the limitation of connecting wires with terminal devices (such as mobile phones, laptops, tablets, etc.), and head-mounted wireless earphones have a better sound field and wearing comfort, so they have become a popular choice for music lovers of all kinds. The device of choice for listening to music.
在真无线头戴式无线耳机中，左右两个耳机内分别设置一个系统芯片(system onchip，SOC，或片上系统)以及与该系统芯片耦合的射频天线，该SOC可以包括射频芯片、蓝牙芯片、数字信号处理器、主动降噪编码器等，则左右侧的耳机均可以与终端设备实现无线连接。目前真无线左右耳机之间的通信有两种实现方式，转发模式或监听模式。在转发模式中，主耳机的SOC与手机建立蓝牙连接，接收手机在空中发送的音频数据，主耳机的SOC通过无线方式将音频数据转发给副耳机的SOC；在监听模式中，主耳机的SOC与终端设备建立蓝牙连接接收终端设备在空中发送的音频数据，副耳监听接收空中的音频数据。若副耳没有监听到音频数据，则主耳机的SOC再以无线方式将音频数据转发给副耳机的SOC。因此，不管是转发模式还是监听模式，主耳机的SOC都将有一部分时间用于与副耳机的SOC通信，此部分时间则无法与手机之间进行数据传输，导致耳机与终端设备之间的实际带宽受限。In a true wireless head-mounted wireless headset, a system chip (system onchip, SOC, or system on chip) and a radio frequency antenna coupled to the system chip are respectively arranged in the left and right earphones. The SOC may include a radio frequency chip, a Bluetooth chip, Digital signal processor, active noise reduction encoder, etc., then the earphones on the left and right sides can be wirelessly connected to the terminal device. At present, there are two ways to realize the communication between the left and right earphones of true wireless, forwarding mode or monitoring mode. In the forwarding mode, the SOC of the main earphone establishes a Bluetooth connection with the mobile phone to receive the audio data sent by the mobile phone in the air, and the SOC of the main earphone wirelessly forwards the audio data to the SOC of the secondary earphone; Establish a Bluetooth connection with the terminal device to receive the audio data sent by the terminal device in the air, and the secondary ear monitors and receives the audio data in the air. If the secondary ear does not monitor the audio data, the SOC of the main earphone wirelessly forwards the audio data to the SOC of the secondary earphone. Therefore, no matter in forwarding mode or listening mode, the SOC of the main earphone will spend part of the time communicating with the SOC of the secondary earphone, and this part of the time cannot perform data transmission with the mobile phone, resulting in actual communication between the earphone and the terminal device. Bandwidth is limited.

在一种可能的实现方式中，基于上述的头戴式无线耳机，假如第一耳机为左耳时，通常会佩戴在左耳，如果终端设备放置在人体右侧(例如右侧的口袋中)，则射频信号需要穿过人体后被第一射频天线接收，这样会导致削弱第一射频天线的接收信号，使得第一射频电路接收到的射频信号较弱。则为解决该问题，所述第二系统芯片还包括：第二射频电路、第二短距离通信核以及第二数字信号处理器；所述第二耳机还包括第二射频天线；所述第二射频电路耦合所述第二射频天线；所述第一短距离通信核，被配置为根据所述第一射频信号，确定第一信号质量参数；所述第二射频电路，被配置为从所述第二射频天线接收所述终端设备发送的第二射频信号，并将所述第二射频信号发送至所述第二短距离通信核；所述第二短距离通信核，被配置为根据所述第二射频信号，确定第二信号质量参数，并将所述第二信号质量参数通过所述第一传输线发送至所述第一短距离通信核；所述第一短距离通信核，被配置为根据所述第一信号质量参数以及所述第二信号质量参数确定所述第一射频信号的质量优于所述第二射频信号的质量时，确定将所述第一射频信号解调为音频编码数据包。这样，通过以上方式当第一射频信号的质量优于第二射频信号的质量时，第一短距离通信核将第一射频信号解调为音频编码数据包，则第一耳机为主耳机，第二耳机为副耳机；反之，如果第二短距离通信核确定第二射频信号的质量优于第一射频信号的质量，则由第二短距离通信核将第二射频信号解调为音频编码数据包，则第二耳机为主耳机，第一耳机为副耳机。In a possible implementation, based on the above-mentioned wireless headset, if the first headset is the left ear, it will usually be worn on the left ear.

如图1所示的一种头戴式蓝牙耳机100，该头戴式无线耳机100的外观结构包括耳机1和耳机2，耳机1和耳机2通过头梁3(例如，可以是图1中示出的弧形支撑架)连接。在一些示例中，如图2所示，基于图1示出的头戴式无线耳机100的外观结构，该头戴式蓝牙耳机100包括一个系统芯片12(system on chip，SOC，或片上系统)，该SOC12可以包括射频芯片、蓝牙芯片、数字信号处理器、编解码器(例如主动降噪编解码器(active noise cancelingcodec，ANC codec))等，该SOC12通常设置在左右两个耳机中的一个耳机(图2中示出的耳机1)中，该SOC12可以通过射频天线11与终端设备(例如图2中的手机200)连接，并接收终端设备传输的音频信号；左右两个耳机之间通过设置在头梁3中的传输线31在两个耳机之间进行信号传输，例如SOC12设置在左侧的耳机1中时，在SOC12接收到手机200传输的音频信号后，即将左耳的音频信号通过左侧的耳机1的扬声器13播放，并通过传输线31将右耳的音频信号传输给右侧的耳机2并通过扬声器23进行播放。这种头戴式无线耳机由于采用了设置在一个耳机中的SOC，算力以及提供的接口受限，并且头梁3中需要设置多条传输线(例如：音频线、电源线以及其他信号线，可能多达20根以上)，这些传输线存在折断的风险，不利于折叠收纳。A head-mounted
为了解决上述问题，本申请实施例还提供一种真无线立体声(true wirelessstereo，TWS)头戴式无线耳机，该头戴式无线耳机可以在两个耳机中分别设置SOC和射频天线。例如，如图3所示的一种头戴式无线耳机100，该头戴式无线耳机100包括耳机1和耳机2，耳机1包括SOC12，以及与该SOC12相耦合的射频天线11；耳机2包括SOC22，以及与该SOC22相耦合的射频天线21。可选的，耳机1还可以包括扬声器13和耳机2还可以包括扬声器23，耳机1中的扬声器13与SOC12相耦合，耳机2中的扬声器23与SOC22相耦合。基于图3所示的头戴式无线耳机，左右耳机之间的通信有两种实现方式，转发模式或监听模式。在转发模式中，主耳机(例如可以是耳机1)的SOC12与手机200建立蓝牙连接，接收手机200在空中发送的音频数据，主耳机的SOC12通过无线方式将音频数据转发给副耳机(例如可以是耳机2)的SOC22；在监听模式中，主耳机的SOC12与手机200建立蓝牙连接，接收手机200在空中发送的音频数据，副耳机监听接收空中的音频数据。若副耳没有监听到音频数据，则主耳机的SOC12再以无线方式将音频数据转发给副耳机的SOC22。因此，不管是转发模式还是监听模式，主耳机的SOC12都将有一部分时间用于与副耳机的SOC22通信，此部分时间则无法与手机200之间进行数据传输，导致耳机与手机之间的实际带宽受限。尤其主耳机与副耳机之间无线传输的占空比越高，对于支持高清音乐播放大难度也越大。In order to solve the above problems, the embodiment of the present application also provides a true wireless stereo (true wireless stereo, TWS) headset wireless headset, and the headset wireless headset can be respectively provided with an SOC and a radio frequency antenna in the two headsets.

The embodiment of the present application also provides a wireless headset. As shown in FIG. 4 , the
上述耳机1可以为左耳机也可以为右耳机。当耳机1为左耳机时，耳机2为右耳机。当耳机1为右耳机时，耳机2为左耳机。示例性的，上述第一传输线31可以设置在连接耳机1和耳机2的机械结构(例如头梁3)之中。例如，头戴式无线耳机还可以包括弧形支撑架，耳机1和耳机2通过该弧形支撑架连接，SOC12与SOC22之间的第一传输线31可以设置于该弧形支撑架中。本申请实施例对于SOC12与SOC22之间的第一传输线31的具体设置位置并不限定，在此仅是示例性说明。The above-mentioned
上述第一传输线31可以是通用异步收发器(universal asynchronous receiver/transmitter，UART)总线、或集成电路内置音频总线(inter—integrated circuit sound，I2S)集成电路总线(inter-integrated circuit bus，I2C)、射频同轴线等。本申请实施例对于第一传输线的具体类型并不限定。此外，耳机1还可以包括扬声器13，扬声器13与SOC12相耦合。耳机2还可以包括扬声器23，扬声器23与SOC22相耦合。The above-mentioned
需要说明的是，该传输信号可以包括第一射频信号本身或者根据第一射频信号生成的信号。具体的，该传输信号可以包括以下示例中数字信号处理器(digital signalprocessor，DSP)之间传输的声道数据，短距离通信核之间传输的音频编码数据包、同步信号、射频信号的信号质量参数，射频电路与短距离通信核之间传输的射频信号，DSP与编解码器之间传输的音频信号等，具体参考下述示例的详细说明。It should be noted that the transmission signal may include the first radio frequency signal itself or a signal generated according to the first radio frequency signal. Specifically, the transmission signal may include channel data transmitted between digital signal processors (DSP) in the following example, audio coded data packets transmitted between short-distance communication cores, synchronization signals, and signal quality of radio frequency signals Parameters, radio frequency signals transmitted between the radio frequency circuit and the short-distance communication core, audio signals transmitted between the DSP and the codec, etc., refer to the detailed description of the following examples for details.
这样，当SOC12通过射频天线11与终端设备无线通信连接，并接收到终端设备发送的第一射频信号后，SOC12可以通过第一传输线31以有线方式向SOC22传输根据第一射频信号生成的传输信号，这样，避免了两侧耳机之间通过无线方式通讯传输信号，因此也避免了耳机与手机之间的实际带宽受限。并且，由于耳机2中也设置有SOC22，因此SOC22可以对耳机1的SOC12传输的传输信号进行处理，避免了所有射频信号均由一侧的耳机进行处理，避免算力受限。In this way, when the SOC12 is wirelessly connected to the terminal device through the
具体的，在第一种应用场景中，参照图5所示，SOC12包括：射频电路121、短距离通信核122以及数字信号处理器(digital signal processor，DSP)123；其中，射频电路121耦合射频天线11；SOC22包括：DSP223；DSP123与DSP223通过第一传输线31连接。其中，射频电路121，被配置为从射频天线11接收第一射频信号，并将第一射频信号发送至短距离通信核122；短距离通信核122，被配置为将第一射频信号解调为音频编码数据包，并将音频编码数据包发送至DSP123；DSP123，被配置为在音频编码数据包中解码第一声道数据以及第二声道数据，并通过第一传输线31将第二声道数据传输至DSP223。示例性的该第一传输线31可以是I2S总线。Specifically, in the first application scenario, as shown in FIG. 5 , the
在下述示例中短距离通信核可以为包括但不限于蓝牙芯片、绿牙芯片、ZigBee芯片、近场通信(near field communication，NFC)芯片或者未来衍生的其他用于短距离无线通信的芯片，本申请实施例对于短距无线通信芯片的具体类型并不限定，下述实施例以短距无线通信芯片为蓝牙芯片为例进行说明。In the following example, the short-distance communication core may include but not limited to Bluetooth chip, green tooth chip, ZigBee chip, near field communication (near field communication, NFC) chip or other chips for short-distance wireless communication derived in the future. The embodiment of the application does not limit the specific type of the short-range wireless communication chip, and the following embodiments take the short-range wireless communication chip as a Bluetooth chip as an example for illustration.
具体的，结合图4和图5所示，当手机200向射频天线11发送携带音频数据的第一射频信号后，射频电路121主要用于从射频天线11接收该第一射频信号；然后，蓝牙芯片122将第一射频信号解调为音频编码数据包(例如：子频带编码或高级音频编码(subbandcoding/advanced audio coding,SBC/AAC)的基础传输头部(base transport header,BTH包)；之后，DSP123对将音频编码数据包进行SBC/AAC解码，生成脉冲编码调制(pulse codemodulation，PCM)码流，该PCM码流包含第一声道数据以及第二声道数据，其中第一声道数据和第二声道数据分别用于在耳机1或耳机2的扬声器中播放。Specifically, as shown in FIG. 4 and FIG. 5, after the
例如，第一声道数据为左声道数据，则DSP123播放该第一声道数据，向耳机1的扬声器13输出第一音频信号，驱动该扬声器13；则第二声道数据为右声道数据，则DSP223播放该第二声道数据，向耳机2的扬声器23输出第二音频信号，驱动该扬声器23。需要说明的是，为提高播放的音质，DSP123还可以对第一音频信号进行如下处理中的一项或多项：主动降噪ANC和均衡EQ之后，输出至扬声器13；同样DSP223还可以对第二音频信号进行如下处理中的一项或多项：主动降噪ANC和均衡EQ之后，输出至扬声器23。上述的主动降噪ANC和均衡EQ功能可以集成于DSP中，也可以有单独的编解码器实现，例如可以在DSP与扬声器之间耦接一个编解码器，参照图5所示，DSP123与扬声器13之间耦接编解码器124，DSP223与扬声器23之间耦接编解码器224，编解码器124和编解码器224可以采用主动降噪ANC编解码器。For example, the first channel data is left channel data, then DSP123 plays this first channel data, outputs the first audio signal to the
此外，在第一场景中的一些示例中，通常DSP123根据耳机1中SOC12上的晶振生成的第一时钟信号播放该第一声道数据；而DSP223根据耳机2中SOC22上的晶振生成的第二时钟信号播放该第二声道数据；由于耳机1中的晶振与耳机2中的晶振提供的时钟信号通常存在20-80us的偏差，因此，生成的第一音频信号与第二音频信号也存在20-80us的偏差，对于发烧友来说，能察觉出来，造成用户体验不好。为了实现耳机1和耳机2的播放同步，参照图6所示，SOC22还包括：短距离通信核222；其中该短距离通信核222可以通过第二传输线32连接短距离通信核122，例如该第二传输线32可以为UART总线。短距离通信核122，还被配置为通过第二传输线32向短距离通信核222发送第一同步信号，并将第一同步信号发送至DSP123；需要说明的是，该第一同步信号可以是SOC12中的晶振提供的一个时钟信号。DSP123，具体被配置为根据第一同步信号播放第一声道数据，生成输出至耳机1的扬声器13的第一音频信号；DSP223，具体被配置为根据第一同步信号播放第二声道数据，生成输出至耳机2的扬声器23的第二音频信号。在一些示例中，需要说明的是，由于DSP123与DSP223通过第一传输线31连接，因此该第一同步信号也可以由DSP123自SOC12中的晶振获取，并通过第一传输线31传输给DSP223。在一些示例中该第一同步信号还可以使用独立的传输线传输，例如直接通过SOC1与SOC2提供的端口之间的输入输出端口(general purpose inputoutput，GPIO)总线传输。In addition, in some examples in the first scenario, usually DSP123 plays the first channel data according to the first clock signal generated by the crystal oscillator on SOC12 in
