例如:该生物特征监测模块500用于检测心率时,当储能电压高于2.1v的时候该生物特征监测模块500上电,进入心率采集模式,当电压降低到2v的时候,该生物特征监测模块500切换至休眠模式,以节省电能。当电压降低到1.9v的时候,该生物特征监测模块500切换至深度睡眠模式或掉电模式,直到电压再次上升到2.1v时回到心率采集模式。
简而言之,储能电压检测电路317检测储能电路316上的储能状态,以便该供电控制模块310根据储能状况控制为生物特征监测模块500的供电电压。
在一个实施例中,如图10所示,该供电控制模块310还可以包括:逆流检测控制电路314,该麦克端811b通过该逆流检测控制电路314连接至该麦克端811b,该逆流检测控制电路314用于检测该储能电路316的电荷是否由该储能电路316流向该麦克端811b,并根据检测结果控制该储能电路316与该麦克端811b导通或者关断。
换句话说,该逆流检测控制电路314监测MIC线路上电流流向和大小,并根据电流情况控制电流路径的通断(作用类似二极管单向导通作用),当MIC上电流向后端的该储能电路316流动时,实现对该储能电路316进行充电。当MIC线路上电流从该储能电路316向麦克端811b流动时,该逆流检测控制电路314用于保护该储能电路316上的电能不被释放掉。
图11是本发明实施例的该逆流检测控制电路314示意性电路图。
具体而言,如图11所示,该逆流检测控制电路314可以包括:第一电阻314a、第一开关314d和比较器314b,该麦克端811b通过该第一电阻314a连接至该第一开关314d,该第一电阻314a的两端分别与该比较器314b的正负输入端相连,该比较器314b的输出端与该第一开关314d相连;其中,该比较器314b的输出信号用于控制该第一开关314d导通或者关断。
更具体地,该比较器314b通过该第一电阻314采集线路上的电流,并比较输出控制信号,该控制信号用于控制该第一开关314d的导通和关断。
应理解,该控制信号可以是比较器314b的输出信号经过驱动或控制门314e驱动后形成的信号。
由此,电流从该麦克端811b流向后端时,控制第一开关314d闭合,为
后端的储能电路316充电;当电流发生从后端电路向该麦克端811b流动时,该逆流检测控制电路314可以控制第一开关314d断开,进而保护后端的储能电路316的电能不被损耗掉。
进一步地,该逆流检测控制电路314还可以包括:第二电阻314f、第三电阻314g和第四电阻314h;其中,该第一电阻314a的一端通过该第二电阻314f连接至该比较器314b的负输入端,该第一电阻314a的另一端通过该第三电阻314g连接至该比较器314b的正输入端,该比较器314b的正输入端通过该第四电阻314h连接至该比较器314b的输出端。
更进一步地,该逆流检测控制电路314还可以包括:第一二极管314c,该第一二极管314c与该第一开关314d并联。以便在该比较器314b和/或控制门314e由于供电不足处于掉电状态的时候,第一二极管314c也能够为该储能电路316充电,而又不会导致该储能电路316电能泄漏。
此外,由于手机3.5mm接口一般有不供电模式、强供电模式和弱供电模式;部分手机供电模式只有强供电模式,而部分手机同时有强供电模式和弱供电模式。
然而,手机3.5mm接口处于强供电模式时,通话模块220可以正常工作,当手机3.5mm接口处于弱供电模式时,通话模块220不一定可以正常工作。
应力,本发明实施例中的通话模块220可以是麦克风(例如,如图4所示),也可以是其它类型的用于通话的模块,本发明实施例不做具体限定。
具体而言,如图2所示,手机接口处于强供电模式时,手机接口的内部电平(Vbias)一般高于1.6v供电电压;而当手机接口处于弱供电模式的时候,手机接口的内部电平可能低于1.8v;应理解,不同手机的强弱供电模式会有一定差异。上述数字仅为示例性说明,本发明实施例对不做限定。
可以理解,相应的手机3.5mm接口处于强供电模式时,本发明实施例中的第一电压为工作电压。然而,当手机3.5mm接口处于弱供电模式时,第一电压由工作电压降为休眠电压(例如,从2.7v工作电压降低到1.4v的休眠电压)。
因此,为了确保能够为该生物特征监测模块500提供充足的工作电压。
在一个实施例中,如图10所示,该供电控制模块310还可以包括:供电触发电路313,该供电触发电路313与该逆流检测控制电路314相连,该
供电触发电路313用于接收第二控制信号,该第二控制信号用于激励该智能终端增大该第一电压。
在一个实施例中,如图10所示,该供电控制模块310还可以包括:第一电压检测电路312,该麦克端811b与该第一电压检测电路312相连,该第一电压检测电路312用于检测该第一电压,并在该第一电压小于或等于该预设门限值时生成上位涉及的第二控制信号,该第二控制信号用于激励该智能终端增大该第一电压。
换句话说,该第一电压检测电路312监测该第一电压是否降低到休眠电压,如果该第一电压降低至休眠电压,供电触发电路313对智能终端100可以施加激活信号,使得该智能终端100输出的该第一电压重新回到工作电压。
图12是本发明实施例的该供电触发电路313的示意性电路图。
具体而言,如图12所示,该供电触发电路313可以包括:
第五电阻312b和金属氧化物半导体(MOS)管313a,该麦克端811b连接至该MOS管313a的漏极,该MOS管313a的源极接地,该MOS管313a的栅极用于接收第二控制信号,该第二控制信号用于激励该智能终端增大该第一电压。
应理解,图12所示的MOS管313a可以是任意一种通过控制端可以控制导通或关断的器件。例如,三级管或模拟开关。
进一步地,如图12所示,该供电触发电路313可以是电压检测电路312生成的经过MCU或其他脉冲产生电路产生的信号。应理解,本发明实施例对该第二控制信号的传输方式不做具体限定,例如,本发明实施例中的该第二控制信号可以由电压检测电路312提供。
需要注意的是:手机接口处于强供电模式的情况可以包括:有线耳机800插入,且麦克风相关应用程序打开(比如通话);或者,当没有麦克风应用程序打开的时候,即通话模块220处于空闲状态;例如,有线耳机800插入后的一段时间内;又例如,按键210按压后的一段时间内;或者,麦克风相关应用停止使用后的一段时间内。相应的,其他时间段,手机接口处于弱供电模式。
下面结合附图13至图18对该供电触发电路313的工作原理进行说明。
图13至图18示例性说明了本发明实施例的第一电压的第一状态,以及
供电触发模块313触发第一状态后第一电压的状态的示意图。
例如,如图13所示,有线耳机800在t10时刻插入,手机无语音应用工作持续一段时间T后,在t11时刻,该第一电压降低至休眠电压。该第一电压的或者输出功率如图13所示。
相应的,该有线耳机800设置有该供电触发电路313时,该第一电压的或者输出功率如图14所示。具体地,有线耳机800在t20时刻插入,手机无语音应用工作持续一段时间T后,在t21时刻该第一电压降低至休眠电压,在t23时刻,该供电触发电路313对智能终端100可以施加激活信号,使得该智能终端100输出的该第一电压重新回到工作电压;进而,在t24时刻,该第一电压重新回到工作电压。以此类推,在t25时刻、t26时刻和t27时刻供电触发电路313进行类似的操作,以此类推。
类似地,图15示出了有线耳机800在t30时刻插入直至t33时刻该第一电压将至休眠电压的示意图。图16为通过该供电触发电路313提升手机音频口供电能力后该第一电压的示意图。
类似地,图17示出了有线耳机800在t50时刻该第一电压为休眠电压的示意图。图18为相应的通过该供电触发电路313提升手机音频口供电能力后该第一电压的示意图。
在一个实施例中,如图10所示,该有线耳机800还可以包括:通话模块220,该麦克端811b连接至该通话模块220。
在一个实施例中,如图10所示,该有线耳机800还可以包括:隔离模块315,该隔离模块315与该生物特征监测模块500相连,该隔离模块315用于隔离传导至该生物特征监测模块500的信号和传导至该通话模块220的信号。
由此,对该通话模块220来说,该隔离模块315对语音信号频段呈现高阻抗特征,保证语音信号不被损失。而对该生物特征监测模块500来说,由于语音信号频段也呈现高阻特征,能够保证该生物特征监测模块500产生的干扰不会传导到该通话模块220的输出信号上,即保证了语音信号不被电路噪声干扰。
应理解,该隔离模块315可以在该逆流检测控制电路314前或后,也可以将该隔离模块315和该逆流检测控制电路314集成设置在同一个电路上,本发明实施例中该隔离模块315的主旨是隔离该通话模块220的语音信号,
即该隔离生物特征监测模块500工作产生的信号对该通话模块220的信号的干扰。
在一个实施例中,如图10所示,该有线耳机800还可以包括:通话功耗检测模块312a,该通话功耗检测模块312a与该通话模块220相连,该通话功耗检测模块312a用于检测该通话模块220的功耗,并根据检测结果确定是否生成第三控制信号,以便该供电控制模块根据该第三控制信号控制该生物特征监测模块500的供电电压。
由此,该通话功耗检测模块312a可以通过监测该通话模块220的功耗消耗,为该供电控制模块310提供该通话模块220的功耗状态信息,该供电控制模块310可以根据该通话模块220的功耗状态控制生物特征监测模块500的工作模式。
例如,如果该通话模块220的功耗较大,生物特征监测模块500进入低功耗模式,确保生物特征监测模块500工作不影响该通话模块220的正常使用。
举例来说,假设该通话模块220为麦克风电路,由于通话功耗检测模块312a具备检测麦克风电路功耗的能力,当麦克风功耗增多的时候,通话功耗检测模块312a检测电压会变化(一般是变小),所以根据通话功耗检测模块312a检测电压来调节生物特征监测模块500的功耗模式,避免生物特征监测模块500与麦克风电路争夺供电,影响音质。
在一个实施例中,如图10所示,该供电控制模块310还可以包括:通话供电控制模块311,该通话供电控制模块311与该通话模块220相连,该通话供电控制模块311用于控制该通话模块220的供电电压。
在一个实施例中,该生物特征监测模块500可以用于进行心率检测。
具体而言,如图10所示,该生物特征监测模块500还可以包括:采集模块400和/或数据处理模块321,该采集模块400与该数据处理模块321相连,该采集模块400用于采集心率数据,该数据处理模块321用于处理该心率数据。应理解,本发明实施例中,该数据处理模块321可以集成在该生物特征监测模块500中,但是,本发明实施例不限于此,例如,该数据处理模块321也可以集成在智能手机中。
进一步的,如图10所示,该供电控制模块310还可以包括:第一供电控制模块318和第二供电控制模块319;其中,该麦克端811b通过该第一供
电控制模块318连接至该采集模块400,该第一供电控制模块318用于控制该采集模块400供电,该麦克端811b通过该第二供电控制模块319连接至该数据处理模块321,该第二供电控制模块319用于控制该数据处理模块321供电。
本发明实施例中,通过该第一供电控制模块318和该第二供电控制模块319,对该第一供电控制模块318连接至该采集模块400的供电分别进行控制,能够更精细地对生物特征监测模块的供电电压进行控制。
应理解,本发明实施例中,可以由该第二供电控制模块319控制该采集模块400供电,也可以由该第一供电控制模块318和该第二供电控制模块319控制该采集模块400供电。
更进一步地,如图10所示,该生物特征监测模块500还可以包括:模式控制模块3110,该模式控制模块3110用于控制该有线耳机800的工作状态处于独立工作模式或者交互工作模式,该独立工作模式指该有线耳机800独立使用该心率数据的工作模式,该交互工作模式指该有线耳机800将该心率数据发送给该智能终端的工作模式。
换句话说,该独立工作模式指:MCU\DSP 320获取采集模块400的心率数据,并计算心率值,通过线控板上的LED或OLED或其他的显示器件指示心率结果。该交互工作模式指:手机通过音频线路(左或右声道线)发送信号到有线耳机80的MCU\DSP 320或采集模块400。MCU\DSP 320通过MIC线路传输编码信号到手机,实现全双工双向传输功能。
应理解,本发明实施例中,终端设备可以处于独立工作模式或者处于交互工作模式仅为示例性描述。本发明实施例不限于此。例如,如图19所示,该终端设备还可以处于掉电模式。
具体地,如图19所示,当处于掉电模式的有线耳机800上电后,可以处于独立工作模式;手机发送开启心率测量命令给该有线耳机800时,该有线耳机800可以将该有线耳机800的工作模式由该独立工作模式切换至该交互工作模式;当手机发送停止心率测量命令给该有线耳机800,或心率测量应用强行退出时,该有线耳机800可以将该有线耳机800的工作模式由该独立工作模式切换至该交互工作模式。
应理解,本发明实施例中,各个模块可以独立设置,也可以集成在一个电路中,本发明实施例不做具体限定。
图20是本发明实施例的有线耳机内置的生物特征监测模块用于进行心率监测时,该有线耳机和智能终端交互的示意性流程图。
如图20所示,该交互过程包括:
2100,该有线耳机800插入手机。

简而言之,该有线耳机800插入手机后,该有线耳机800的供电控制模块310会开始工作,给该生物特征监测模块500上电。该生物特征监测模块500上电后默认工作在独立工作模式。该有线耳机800可以监听该有线耳机800的命令,当手机发出交互模式请求命令时,该有线耳机800切换到交互工作模式。当手机心率测量应用强行退出,或手机发送切换到独立工作模式的命令时,该有线耳机800切换到该独立工作模式。
在一个实施例中,该生物特征监测模块500还可以包括:接收前端,该接收前端用于接收该智能终端100发送的切换请求,该切换请求用于请求该有线耳机800将该有线耳机800的工作模式由该独立工作模式切换至该交互工作模式,并将该切换请求的解调数据发送给该模式控制模块3110。
由此,使得该模式控制模块3110能够控制该有线耳机800工作在该独立工作模式或该交互工作模式;
其中,接收前端可以是手机和MCU\DSP 320之间的通讯的前级信号的处理电路。例如,滤波器和增益调节电路。手机的信息经过编码后通过左声道线路或右声道线路发出,经过接收前端处理提供给MCU\DSP 320,以便该MCU\DSP 320进行解码。具体地,如图10所示,该接收前端可以包括:第一接收前端3111和第二接收前端3112。
在一个实施例中,该生物特征监测模块500还可以包括:心率指示控制模块325和心率指示模块330;其中,该心率指示控制模块325根据该数据处理模块321的处理结果生成第四控制信号,以便该心率指示模块330根据
该第四控制信号指示心率检测结果。
在一个实施例中,该心率指示模块330通过多个发光二极管LED指示多个心率强度区间,该多个LED与该多个心率强度区间一一对应,该多个LED具有不同的颜色。
具体地,如图21所示,该心率指示模块330可以通过LED或OLED或其他可视化设备指示心率强度。例如:利用几个不同色彩的LED指示不同的心率强度区间。例如,用蓝色LED代表心率在30BPM~80BPM之间;绿色LED代表心率在80~110BPM之间;用红色代表110~150BPM之间;用黄色代表150~180BPM之间;用橙色代表心率区间在180~220BPM之间。
应理解,上述心率强度区间和指示方式仅为本发明实施例的示例,本发明实施例不限于此。
例如,该心率指示模块330可以显示颜色的同时,也可以配合不同的闪烁频率指示心率快慢。例如,心率LED闪烁频率越高时,心率相应的也越高。
又例如,该心率指示模块330也可以使用一个LED通过不同的闪烁速度来指示心率区间。
在一个实施例中,MCU\DSP 320还可以包括通信控制模块322和/或功耗控制模块324,其中,通信控制模块322用于控制该有线耳机800和该智能终端100之间的通信,该功耗控制模块324用于控制该生物特征监测模块500的功耗模式,具体地,该功耗控制模块324可以控制该生物特征监测模块500处于低功耗模式,或者,该功耗控制模块324可以控制该生物特征监测模块500处于正常工作的功耗模式。

例如,如图22所示,采集模块400可以设置在左耳塞840b上。
又例如,采集模块400也可以设置在右耳塞840a上,或者同时设置在右耳塞840a和左耳塞840b上等等。
又例如,如图22所示,该供电控制模块310可以设置于线控板830上。
又例如,该供电控制模块310可以设置于右耳塞840a和/或左耳塞840b上,该供电控制模块310也可以集成设置在MCU\DSP 320内等等。本发明实施例不做具体限定。
又例如,该供电控制模块310可以拆分成多个模块分别设置于线控版830、左耳塞840b以及右耳塞840a上。
最后需要注意的是,由于本发明实施例中的耳机不需要电池,因此无需充电,不用携带充电线缆或充电器。而且使用方便,插入目标设备(例如,手机)就可以使用,进而降低耳机的生产成本。
进一步地,本发明实施例中的耳机能够支持在耳机上完成心率测量并指示心率区间;还能够支持生物特征监测模块和耳机原有基本功能(例如,语音通讯,音乐播放)同时工作;还能够支持根据麦克风功耗变化动态控制生物特征监测模块的功耗和工作模式,进而保证原有基本功能在任何时候都能正常工作;还能够支持根据音频应用的使用情况调节生物特征监测模块的工作模式;还能够支持触发处于休眠模式的音频接口提升输出能力,满足负载电路功耗需求。
