传统有线耳机一般是音频插头通过音频线(一般为四根MIC线，GND线，HPL线和HPR线)接至线控制板(包括麦克风芯片，线控器用于将按键动作以特征信号从MIC线上传)及左右耳塞，组成一个完整的线控耳机。传统立体声耳机具有优良音质，耐用，低成本等优点，因此得到了广泛使用。
蓝牙无线耳机一般是通过蓝牙收发器接受和发射射频信号，接至音频处理器用于处理音频信号后接至麦克风和左(或右)耳塞，完整的蓝牙耳机还包括电池及电源管理。蓝牙无线耳机的便捷性，使其在各种特殊场合下具有必要性，如在开车过程中，因此也得到了广泛的应用。
尽管这两种耳机各有优点，但是它们的基本功能类似，在对两种耳机都有需求时，同时携带两种耳机变得很不方便。
发明内容

本发明的多功能耳机，其包括：左右耳塞、音频插头和混合控制板，且左右耳塞、混合控制板和音频插头之间通过音频线连接，关键技术在于：
混合控制板由上板和下板两个子板组成，且上板为传统耳机的线控制板，下板为蓝牙耳机主板；
当上下两板拆开时，该多功能耳机分为两部分，蓝牙耳机主板控制与其连接的一个耳塞构成单声道音频的蓝牙耳机；传统耳机的线控制板控制另一个耳塞及音频插头组成单声道有线的有线线控耳机；
当上下两板相扣时，蓝牙耳机主板控制蓝牙耳机关闭，传统耳机的线控制板控制左右耳塞和音频插头构成有线线控耳机。
混合控制板的位置关系有两种，第一种为：所述混合控制板一端通过音频线与一个耳塞相连接，另一端通过音频线与另一个耳塞的音频线混合后连接到音频插头上。第二种为：所述混合控制板一端分出两条音频线分别与左右耳塞相连接，另一端通过音频线与音频插头相连接上。
第一种位置关系中作为上板的传统耳机的线控制板：

图2为本发明的多功能耳机后视图；
图3为本发明的多功能耳机正视分解示意图；
图4为本发明的多功能耳机后视分解示意图；
图5本发明的多功能耳机的混合控制板结构示意图；
图6为本发明的多功能耳机另一实施例的结构示意图；
图7为本发明的多功能耳机另一实施例的分解示意图。
具体实施方式
以将所述混合控制板一端通过音频线与一个耳塞相连接，另一端通过音频线与另一个耳塞的音频线混合后连接到音频插头上为实施例进行详细论述。
图1为本发明的多功能耳机的正视图；图2为本发明的多功能耳机的 后视图；图3为本发明的多功能耳机正视分解示意图；图4为本发明的多功能耳机后视分解示意图；正视和后视以混合控制板为准。如图1-图4所示，该多功能耳机包括左右耳塞、连接线、混合控制板、以及音频插头。整个耳机除了混合控制板，其它都类似于传统的有线耳机。其中，混合控制板由两个子板组成，上板和下板，两板均有按键及进音孔，上板有音频线(MIC，GND和HPL)接至音频插头，下板有音频线(GNDB和HPLB)接至左耳塞。
混合控制板的上板为传统耳机的线控制板，板上有麦克风，线控器，都接至MIC线，另有一插拔探测模块。板外壳应有三个按键+，键C，键-，分别接至线控器，一个进音孔及一个通孔，进音孔内部对应麦克风，而通孔位置则对应另一板上的进音孔。板外壳与按键对立的另一面还有四个插针电极(也可以是平面电极等其它形式)，分别接至MIC，GND，HPL和GNDa，一个电阻Ra接在GND和插拔探测模块之间，GNDa接至插拔探测模块(可以是简单的电压比较器及脉冲产生)，四插针的插拔状态识别后，探测模块驱动多次按下按键c，通知主机。
本发明的设计关键在于混合控制板的下板。混合控制板的下板为蓝牙耳机主板，包括蓝牙收发器，音频处理器，电源管理及控制器，麦克风，电池，USB接口等所有蓝牙耳机所需要的元器件，不同的是其耳塞为外接耳塞，由音频处理器中的音频功放驱动。板外壳应有一个按键Bc接至内部控制器，一个进音孔及一个通孔，同样进音孔内部对应麦克风，而通孔位置则对应另一板上的进音孔。板外壳与按键Bc在同一面上还有四个插孔电极(也可以是平面电极等其它形式)，与上板插针电极相对应的，分别MICB,GNDB,HPLB,CTRLB。同样此板上需要有插拔探测短路，这里以最简单的电路实现，电阻Rb接在VDD和CTRLB之间，这样在两板相扣时，与Ra组成分压电路，如果Rb＞＞Ra，CTRLB＝GNDa＝GNDB，而在两板 拆开时，CTRLB＝VDD。内部控制器内置电压探测电路监测CTRLB，继而实现了最为简单的插拔探测功能。注意还有不同的是，MICB线接至控制器部分，控制器可以硬件或软件模拟方式，针对不同品牌的线控算法来驱动MICB，用于与主机间的线控数据通讯。MICB和HPLB线接至电源管理部分，控制器中可以内置DC/DC(用于MICB线的直流充电)或AC/DC(用于HPLB线的交流充电)电源模块，用于主机对用蓝牙耳机的充电。
进一步的，两板内面的四插针/插孔(或更多数量，或其它任何方式，比如平面电极以磁铁相吸)，可实现机械和电学连接,非常方便的拆卸和扣紧。
进一步的，可以控制同时启动两板上的麦克风，实现多麦克风录音，增强音效。下板上也可以加传感器等功能，与手机可以以有线方式或无线方式传输数据。
进一步的，由于两板的接口为标准形式，其间可以增加一块或多块中间板，以增加任何适配与上下板接口的任何功能板，只要其一面是插针另一面是插孔即可，由此可以实现混合控制板的功能的扩展。
结合图5描述本发明的多功能耳机的工作步骤如下：
当上下两板相扣时，MIC＝MICB,GND＝GNDB,HPL＝HPLB,GND＝CTRLB,CTRLB被置低电平，将蓝牙耳机完全关闭。上下音频线接通，耳机即可组成一个完整的立体声有线线控耳机。同时，主机也可以通过音频线MIC和或HPL给蓝牙耳机的电池充电，比如主机低阻高电平直流或交流驱动控制器中的DC/DC或AC/DC模块，用于充电。注意当主机用交流信号驱动HPL线时，频率必须大于音频频率使得人耳听不到，而且耳塞在此频率下的阻抗大大增加从而不用消耗太多能量在耳塞中。
当上下两板相扣时，但音频插头未插入主机时，可以按下键Bc手动开启蓝牙耳机功能或者简单数据传输功能做为防丢器之用。
当上下两板相扣时，音频插头插入主机，在实现有线的耳机通话时，当此时拆开两板时，下板的CTRLB由低电平变为高电平，蓝牙耳机自动启动，上板的插拔探测模块识别两板拆开后，通知主机，启动无线蓝牙通讯，与配对的蓝牙耳机通话，继而实现蓝牙耳机的热拔启动。
当上下两板相扣时，音频插头插入主机，可以手动按下键Bc多次，来通知音频处理器启动下板上的麦克风，加上上板上的麦克风，可以有两个麦克风同时工作，实现多麦克风录音，增强音效，比如立体声录音，或者背景噪音消除，等等。
当上下两板拆开后，电极断开，下板的CTRLB被置高电平，开启整个蓝牙耳机，使用方式跟传统蓝牙耳机一模一样。但是此蓝牙耳机为单声道音频。
当上下两板拆开后，电极断开，上板，右耳塞，音频线及音频插头组成一个完整的单声道有线的线控耳机。使用方法跟传统耳机一模一样。
另一个实施例为将所述混合控制板一端分出两条音频线分别与左右耳塞相连接，另一端通过音频线与音频插头相连接上，如图6和图7所示，变化为：作为上板的传统耳机的线控制板，一端通过音频线MIC，GND，HPL，HPR与音频插头连接；另一端通过GND和HPR与一耳塞连接。其它一切都不变，包括蓝牙耳机不变，实现方法参照上述实施例，在此不做详细论述。
惟以上所述者，仅为本发明的较佳实施例而已，举凡熟悉此项技艺的专业人士。在了解本发明的技术手段之后，自然能依据实际的需要，在本发明的教导下加以变化。因此凡依本发明申请专利范围所作的同等变化与修饰，都应仍属本发明专利涵盖的范围内。
