具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
本申请实施例提供的耳机被构造为至少部分能够佩戴在用户双耳中的一个耳朵或两个耳朵附近或耳朵内，尽管耳机的结构形状呈现多种多样变化，然而，本申请实施例提供的技术方案可适用于任何结构形状的耳机，诸如包括入耳式耳机、头戴式耳机或挂耳式耳机等等。
尽管“耳机”的名称在其它业务或技术领域被其它名称所代替，例如，“耳机”被“通话器”或“助听器”或“音箱”或“音响”所代替，然而，本申请实施例提供的技术方案可适用于任何具有类似或相同于“耳机”完成同一类功能的音频设备。
任何用户都可以基于本申请实施例所揭示的技术方案或者根据所揭示的技术方案，容易想得到将本申请实施例提供的技术方案用在任何合适的工作模式中。例如，基于本申请实施例提供的技术方案，其可以将主耳机与从耳机切换至双耳机连接模式、双耳机断开模式、双耳机同时使用模式、单耳机使用模式或模仿对讲机使用模式等等。
请参阅图1，图1是本申请实施例提供一种耳机系统。如图1所示，耳机系统100包括第一音频源设备12、主耳机14以及从耳机16，主耳机14与从耳机12无线连接，并且，主耳机14还与第一音频源设备12无线连接。
本文涉及到“无线连接”可以为任何合适的无线通信连接方式，诸如蓝牙等等。在本实施例中，主耳机14通过蓝牙方式分别与从耳机16和第一音频源设备12连接。
第一音频源设备12(包括下述涉及的各个音频源设备)可以是任何合适的，具有提供音频内容或者播放音频数据能力及存储能力的设备，诸如智能手机、平板电脑、MP3播放器、个人电脑、手提电脑、个人音响、CD机或者其它智能/非智能终端设备。第一音频源设备12耦合至至少一个用于存储音频数据的存储介质中，这些存储介质可以是用户终端设备内的存储器，也可以是互联网上的存储介质，并从存储介质中获取音频文件。此外，该第一音频源设备12还可以是一种或者多种电子设备的组合，例如，智能手机以及与其连接的模数转换器(DAC)。
在一些实施例中，第一音频源设备12可以通过内部集成或者外部的蓝牙模块或者蓝牙芯片实现与主耳机14/从耳机16的连接。当两台具有蓝牙功能的设备建立连接时，它们会获取对应设备提供的协议。只有使用相同协议的设备才能交换数据。其中，第一音频源设备12支持A2DP与AVRCP协议，并且还支持以下音频编码方式：SBC(Sub Band Coding次频带编码)、MP3、AAC(Advanced Audio Coding，高级音频编码)、Apt-X等格式。其中，SBC编码格式的编码率44.1kHz双声道最大为328kbit/s，AAC编码格式的编码率可达320kbit/s，Apt-X编码格式的编码率可达352 kbit/s。
在另一些实施例中，第一音频源设备12还可以为本地音频设备，其中，本地音频设备包括USB接口设备和analog接口设备(ADC/SPDIF/I2S)。本地音频接口将音频数据缓存在第一音频源设备12的内部RAM中，并使用SBC编码。
在蓝牙通信中，具有蓝牙功能的设备不需要实现全部的蓝牙规范。为了支持不同的蓝牙设备之间的兼容，在蓝牙规范中定义了一些应用层协议(profile)，其用以定义具有蓝牙功能的设备之间如何实现一种连接或者应用。
其中，A2DP(Advenced Audio Distribution Profile，高级蓝牙音频传输模型协议)属于上述的蓝牙协议profile中的一个子集。用于传输高质量音乐 文件数据的协议堆栈和使用方法，A2DP是专门为使用蓝牙传送立体声音频而制定。
AVRCP(Audio/Video Remote Control Profile，音频/视频远程控制规范，用于提供控制TV、Hi-Fi设备等的标准接口。此配置文件用于许可单个远程控制设备(或其它设备)控制所有用户可以接入的A/V设备。
如图1所示，主耳机14只能够蓝牙连接一个第一音频源设备12。并且，当主耳机14蓝牙连接从耳机16时，主耳机14接收并播放第一音频源设备12传输的音频信号，并且，从耳机16通过侦听方式获取第一音频源设备12传输给主耳机14的音频信号，从耳机16播放该音频信号，从而实现双体立体声。
如前所述，由于主耳机14与从耳机16为无线连接，其极大扩展主/从耳机的自由度，用户可以更加灵活地使用主/从耳机，并实现了真正无线立体声(TrueWireless Stereo，TWS)效果。
值得提醒的是：主耳机14与从耳机16的角色不是固定不变的。对于不同的音频源设备，两者的角色可以互换。例如，请参阅图2，图2是本申请实施例提供另一种耳机系统。如图2所示，耳机系统100还包括第二音频源设备18，第二音频源设备18与从耳机16蓝牙连接。
对于第一音频源设备12而言，“主耳机14”为主耳机，“从耳机16”为从耳机。对于第二音频源设备18而言，“从耳机16”为主耳机，“主耳机14”为从耳机。
在上述各个实施例中，耳机系统100可以工作在TWS工作模式下。在TWS工作模式下，单个耳机最多可以连接1个音频源设备，1组TWS会话最多连接2个音频源设备。
本申请实施例对TWS会话作出进一步阐述：
1、完成配对。在进入TWS会话之前，第一音频源设备12与主耳机14蓝牙配对，第二音频源设备18与从耳机16蓝牙配对。
2、建立TWS会话。第一音频源设备12与主耳机14建立TWS会话，第二音频源设备18与从耳机16建立TWS会话。
3、播放音频。TWS会话建立成功后，当第一音频源设备12播放音频信号时，主耳机14接收第一音频信号，从耳机16通过侦听方式获取第一音频信号。当第二音频源设备18播放第二音频信号时，从耳机16接收第二音频信号，主耳 机14通过侦听方式获取第二音频信号。
阐述完TWS会话过程，本领域技术人员可以通过任何合适的耳机电路以完成上述TWS会话过程。
请参阅图3，耳机300包括换能器31、无线通信模块32、控制模块33、音频解码芯片34及扬声器35，控制模块33分别与换能器31、无线通信模块32、音频解码芯片34以及扬声器35连接。
换能器31用于采集环境噪声信号或音频信号，该音频信号可以为用户发出的，亦可以为其它音频源设备发出的。换能器31可以设置于耳机300的壳体外部的合适位置。换能器31可以为任何合适的声电换能器件，诸如麦克风之类。
无线通信模块32用于与音频源设备或主/从耳机无线连接，无线通信模块32接收音频源设备或主/从耳机传输的音频信号。无线通信模块32可以为诸如蓝牙(Bluetooth)、射频识别(RFID)、红外数据协会(IrDA)、超宽带(UWB)或ZigBee这样的短距离通信技术。
控制模块33作为耳机300的控制核心，控制模块33配合其它器件共同能够完成耳机300的各类功能。例如，控制模块33接收换能器31采集的音频信号，并通过无线通信模块32传输给音频源设备。再例如，无线通信模块32接收音频源设备传输的音频信号，并在控制模块33的控制下，发送给音频解码芯片34，音频解码芯片34对音频信号进行解码处理，控制模块33将解码后的音频信号通过扬声器35播放出。再例如，控制模块33接收换能器31采集的环境噪声信号，并根据环境噪声信号产生与环境噪声信号振幅相同、相位相反的噪声消除信号，以降低环境噪声的干扰。
在一些实施例中，无线通信模块32、控制模块33以及音频解码芯片34可以封装在同一集成芯片上，在此不对无线通信模块32、控制模块33以及音频解码芯片34的电路结构做出任何限制。
此处，当耳机300为主/从耳机时，相对应地，换能器31为第一/第二换能器，无线通信模块32为第一/第二无线通信模块，控制模块33为第一/第二控制模块，音频解码芯片34为第一/第二音频解码芯片，扬声器35为第一/第二扬声器。
请参阅图3a，控制模块33包括处理器331以及存储器332。
处理器331与存储器332连接。处理器331可以通过使用以下各项中的至 少一种来实现：专用集成电路(ASIC)、数字信号处理器(DSP)、数字信号处理装置(DSPD)、可编程逻辑器件(PLD)、现场可编程门阵列(FPGA)、处理器、控制器、微控制器、微处理器、执行这些功能的其他电子单元。
在本实施例中，处理器331的数量可以为1个，亦可以为多个。
存储器332包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他非易失性固态存储器件。在一些实施例中，存储器332可选包括相对于处理器331远程设置的存储器，这些远程存储器可以通过网络连接至耳机。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
存储器332用于存储非易失性软件程序、非易失性计算机可执行程序以及模块，如本文涉及的耳机无线通信方法/装置对应的程序指令/单元。处理器331通过运行存储在存储器332中的非易失性软件程序、指令以及单元，从而执行耳机的各种功能应用以及数据处理，即实现上述方法实施例耳机无线通信方法。
进一步的，本文还提供了一种计算机程序产品，所述计算机程序产品包括存储在非易失性计算机可读存储介质上的计算机程序，所述计算机程序包括程序指令，当所述程序指令被耳机执行时，使所述耳机执行本文所述的耳机无线通信方法。其中，该耳机可以为主耳机或从耳机。
请参阅图4，图4是本申请实施例提供一种耳机建立无线通信方法的流程示意图。如图4所示，耳机建立无线通信方法400包括：
41、音频源设备向主耳机发送第一连接信息与音频信号；
在本实施例中，主耳机根据第一连接信息与音频源设备建立蓝牙连接。第一连接信息包括蓝牙协议、设备控制信息等等，音频信号包括音乐数据或通话数据。
42、主耳机将第二连接信息发送给音频源设备，维持主连接与相关通信；
43、主耳机向从耳机发送第三连接信息与上述音频信号；
在本实施例中，从耳机根据第三连接信息与第一耳机建立蓝牙连接。第二连接信息包括蓝牙协议、设备控制信息等等。于是，从耳机便可以侦听音频源设备向主耳机发送的音频，该音频包括音乐数据或通话数据。
44、从耳机向主耳机发送第四连接信息。
在本实施例中，第四连接信息包括蓝牙协议、设备控制信息等等。
至此，主耳机与从耳机和音频源设备建立无线通信。
基于上述主/从耳机/音频源设备之间的通信架构，本申请实施例提供一种耳机无线通信方法。
请参阅图5，该耳机无线通信方法500包括：
51、主耳机基于标准通信协议与音频源设备无线通信；
52、主耳机与从耳机无线通信；
在本实施例中，标准通信协议可以为标准蓝牙协议，因此，主耳机与从耳机和音频源设备之间的通信为蓝牙通信。
在标准蓝牙协议下，主耳机、从耳机以及音频源设备皆在标准蓝牙时序控制下，共同相辅相成、互相协作而完成某项功能的。
53、音频源设备向主耳机发送数据；
在本实施例中，上述数据可以为音频数据，亦可以为其它通信数据，其中，音频数据包括音乐数据或者通话数据。
54、从耳机通过侦听模式获取音频源设备发送给主耳机的数据；
55、在标准通信协议下，延长主耳机与音频源设备通信的标准接收时间，获得扩展接收时间；
56、在标准通信协议下，延长主耳机与音频源设备通信的标准发送时间，获得扩展发送时间；
57、主耳机与从耳机通过扩展接收时间进行无线通信；
58、主耳机与从耳机通过扩展发送时间进行无线通信。
在本实施例中，请参阅图6，在标准蓝牙协议中，音频源设备的工作时序可以依序为：标准发送时间长度TX1-标准空闲时间SL-标准接收时间RX1-标准空闲时间SL……标准发送时间TX2-标准空闲时间SL-标准接收时间RX2……。其中，通过音频源设备的标准发送时间，音频源设备可以向主耳机发送数据。通过标准空闲时间，音频源设备不与主耳机互相收发数据。通过标准接收时间，音频源设备可以接收主耳机发送的数据。
标准蓝牙时序可以依序为：标准接收时间RX4-标准空闲时间SL-标准发送时间TX3……标准接收时间RX6-标准空闲时间SL-标准发送时间TX7……。
主耳机的工作时序可以依序为：标准接收时间RX9-扩展接收时间RX10-标准空闲时间SL-标准发送时间TX5-扩展发送时间TX6-标准空闲时间SL……标准 接收时间RX12-扩展接收时间RX13-标准空闲时间SL-标准发送时间TX7-扩展发送时间TX8……。
通过主耳机的标准接收时间RX9，主耳机可以接收音频源设备发送的数据，并且，主耳机还可以通过扩展接收时间RX10接收从耳机的数据获取情况，其中，从耳机的数据获取情况包括从耳机通过侦听模式获取音频源设备发送给主耳机的数据，还可以包括从耳机与主耳机通信数据或者一些处理数据等等。
从图6可知，标准接收时间RX9与扩展接收时间RX10之间，或者，标准接收时间RX12与扩展接收时间RX13之间是不存在切换的，亦即，主耳机在标准接收时间工作完后，并不用切换地继续在扩展接收时间内工作，因此，主耳机能够无需切换，更加高效地接收数据。
主耳机通过标准接收时间TX5接收音频源设备发送的数据后，主耳机将主耳机的数据接收情况以及从耳机的数据获取情况整合后，并将整合后的主耳机的数据接收情况以及从耳机的数据获取情况发送给。举例而言：主耳机判断主耳机的数据接收情况和/或从耳机的数据获取情况是否存在错误，主耳机根据判断结果，请求音频源设备重发/另发数据，例如，若主耳机的数据接收情况为有误和/或从耳机的数据获取情况为有误，主耳机通过标准发送时间请求音频源设备重发数据；若主耳机的数据接收情况和从耳机的数据获取情况均为无误，主耳机通过标准发送时间请求音频源设备另发数据。
主耳机请求完音频源设备重发/另发数据后，通过扩展发送时间TX6，向从耳机发送确认信息，以使从耳机重新侦听/另行侦听数据。例如，当主耳机根据主耳机的数据接收情况与从耳机的数据获取情况，判断主耳机的数据接收情况和/或从耳机的数据获取情况未满足预设条件，主耳机向从耳机发送“接收未成功”的确认信息，于是，从耳机便重新侦听音频源设备向主耳机发送的音频。当主耳机根据主耳机的数据接收情况与从耳机的数据获取情况，判断主耳机的数据接收情况和/或从耳机的数据获取情况满足预设条件，主耳机向从耳机发送“接收成功”的确认信息，于是，从耳机便另行侦听音频源设备向主耳机发送的下一帧音频。
主耳机在标准空闲时间下，主耳机不与音频源设备互相收发数据。在标准发送时间下，主耳机可以向音频源设备或从耳机发送数据。
请再参阅图6，从耳机的工作时序可以依序为：标准侦听时间RX16-切换时 间QH1-从发送时间TX9-标准等待时间WA1-从接收时间RX17-标准空闲时间SL……标准侦听时间RX19-切换时间QH2-从接收时间TX10-标准空闲时间SL-标准等待时间WA2-从接收时间RX20-标准空闲时间SL……。
在标准侦听时间RX16下，从耳机可以侦听音频源设备发送的数据。
在切换时间QH1下，由于主耳机不与音频源设备互相收发数据，从耳机便不与音频源设备互相收发数据，并且，当标准侦听时间RX16对应的时序与主耳机的标准接收时间RX9对应的时序相同时，切换时间QH1对应的时序与标准侦听时间RX16对应的时序相反，以便从耳机根据切换时间QH1可靠地切换至发送模式，该发送模式为从耳机向主耳机发送数据。
在从发送时间TX9下，从耳机向主耳机发送数据获取情况。
在标准等待时间WA1下，从耳机工作在等待模式，此时，主耳机向音频源设备发送数据。
在从接收时间RX17下，从耳机工作在接收模式，接收主耳机发送的确认信息。可以理解的是，标准等待时间WA1对应的时序与从接收时间RX17对应的时序可以是相同，亦可以是不相同的，例如，标准等待时间WA2对应的时序与从接收时间RX20对应的时序相同。因此，当标准等待时间对应的时序与从接收时间对应的时序相同时，从耳机无需将等待模式切换至接收模式，从而提高通信效率。
需要说明的是，在上述各个实施例中，上述各步骤之间并不必然存在一定的先后顺序，本领域普通技术人员，根据本申请实施例的描述可以理解，不同实施例中，上述各步骤可以有不同的执行顺序，亦即，可以并行执行，亦可以交换执行等等。
综上，主耳机通过扩展接收时间或扩展发送时间与从耳机无线通信，从而提高从耳机接收数据的可靠性以及主/从耳机之间的通信效率。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换； 而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
