在主控电路6上，除核心处理器内置有智能语音模块外，本发明还可以在主控 电路6上设置独立运作的智能语音模块(图中未示出)，该智能语音模块包括核心电路板、内置存贮器和以语音识别软件开发公司推出的嵌入式语音合成芯片为主的主控芯片。
1、核心处理器
用于控制显示屏4、音频功放工作，接收处理由机壳上的MIC56输入的语音信息，接收处理由机壳上的触摸按键、其它按键输入的信息，接收处理由USB接口58输入的数字信息和接收及发出与内置天线互联的信息处理。
所述内置天线包括蓝牙天线、手机天线和GPS天线。
音频功放通过喇叭57输出音频信息。
通常，为了降低能耗，该核心处理器常处于待机状态。
所述SIM/存储卡槽55通过手机SIM卡和外置存储卡的卡槽与核心处理器相接。
在核心处理器上还连接有内置的手机号码卡。
2、值班处理器
本发明设置专门的处理器来承担对常态工作模块的控制，其可大大降低核心处理器的工作负荷。
值班处理器的工作电压由供电电池7直接提供，其它功能模块(如核心处理器、显示屏4、音频功放等)的工作电压由该值班处理器控制连接。
3、功能模块电路
主要包括三大模块，分别为开关控制模块、充电管理模块和耳充开关模块。
1)开关控制模块
该开关控制模块的作用是：在使用者通过语音输入、触摸按键输入或将TWS耳机3从充电座2上取出而触发值班处理器做相应的工作。
这些工作如：
通过显示屏4和喇叭57的组合模式或者显示屏4和TWS耳机3的组合模式播放来自于网络平台或内存的流媒体信息；通过蓝牙天线与手机互联并完成与他人的远程信息交流；通过GPS天线获知佩戴该多媒体适配机的使用者的运动信息。
所述开关控制模块由识别电路、所述值班处理器、处理器电源开关和处理器电源模块构成。
识别电路，用于采集TWS耳机3是否放置在充电座2内的存取信息，并且将该存取信息传送给所述值班处理器。
值班处理器，当TWS耳机3被摘取脱离所述的充电座2后，该值班处理器向所述 处理器电源开关发出打开处理器电源模块的指令。
处理器电源模块，将供电电池7的电能转换成多规格的电压并向音频功放、显示屏4和核心处理器提供正常的工作电压(显示器的工作电压有5V，3.3V等；核心处理器的工作电压有5V，3.3V，1.8V,1.5V,1.2V等；音频功放的工作电压有5V，3.3V等)。之后，通过耳机、自带的MIC56或触摸按键选择播放的流媒体，从而实现网络播放的功能。
通过语音输入触发值班处理器做上述相应工作的过程如下：
通过MIC给核心处理器(或者独立设置的智能语音模块)输入语音信息，该核心处理器给值班处理器发出指令启动所述的处理器电源开关和处理器电源模块工作，向音频功放、显示屏和核心处理器提供正常的工作电压。
通过触摸按键输入触发值班处理器做上述相应的工作过程如下：
通过触摸按键直接给值班处理器输入相应的触发指令，该值班处理器向所述处理器电源开关发出打开处理器电源模块的指令，并向音频功放、显示屏和核心处理器提供正常的工作电压。
核心处理器有连接移动网络的天线，有可以放置手机卡的卡槽。网络信号可以通过手机卡连接到运营商提供的网络上，通过核心处理器内置的应用软件，可以实现上网功能，可以实现非常多的网络应用。处理器在接收到网络内容时可以进行音视频的处理，音频信号可以通过核心处理器的蓝牙功能将音频信号发到TWS耳机3上，用耳机来收听音频，也可以通过所述音频功放及该多媒体适配机自带的SPK进行音频播放。
网络内容可以存储到外置的存储卡，也可以存储在核心处理器自带的内存中。
核心处理器控制显示器，通过显示器可以播放经核心处理器处理完成的视频信号。
核心处理器控制GPS天线模块，可以记录携带该多媒体适配机人的运动信息，并把该运动信息记录在核心处理器中，可以通过耳机、显示器和SPK进行音频及视频展示。
2)充电管理模块
本发明的多媒体适配机仅设置一个USB接口58，该USB接口58即可作为向内设有供电电池7和TWS耳机3充电的接口，也可作为所述供电电池7为外接的移动设备(如手机、移动电脑、小电器等)充电的接口。
完成上述兼容性功能主要是在USB接口58与值班处理器之间设置了该充电管 理模块。该模块由电压输入检测电路、电流流向转换模块、电池充电模块和所述的值班处理器构成。
电压输入检测电路，用于检测USB接口58是连接在外接充电电源上(此时，USB接口58应该有电压输入信号)，还是连接在待充电设备上，之后，将该信息传送给所述的值班处理器。
电流流向转换模块，用于切换电流流动的方向。
当USB接口58连接在外接充电电源上时，即说明需要对内设的供电电池7充电。
此时，所述值班处理器向该电流流向转换模块切换电流流动方向的指令。使该电流流向转换模块的电流流动方向切换为输入方向，在此情况下，有如下两种供电情况：
第一种：使外接充电电源输入的电流经所述电流流向转换模块通过电池充电模块为所述供电电池7充电。
第二种：使外接充电电源输入的电流经所述电流流向转换模块为放置在充电座2内的TWS耳机3(该耳机内置有电池)充电。
当USB接口58连接在待充电设备上时，即说明需要用内设的供电电池7为外接的待充电设备(即前述的移动设备)充电。
通过按键启动，所述值班处理器向该模块发出电流流动方向为输出方向的指令，使所述供电电池7输出的电流由电池充电模块、电流流向转换模块至USB接口58为所述待充电设备充电。
对耳机充电和外接设备充电时，充电状态和电量大小均可通过设置在机壳上的指示灯显示充电状态。
3)耳充开关模块
本发明的多媒体适配机对放置在充电座2内的TWS耳机3充电有两种方式，一种是通过连接在USB接口58上的外接电源给该耳机充电，另一种是用内设的供电电池7为该耳机充电，两种方式电流的流动和控制程序不同，现分别叙述如下：
第一种，即为前述“充电管理模块”中述及的充电模式。
第二种，是在所述电流流向转换模块与值班处理器之间设置的耳充开关模块，该耳充开关模块由所述的识别电路、耳充电源开关、耳充管理模块和所述的值班处理器构成。
识别电路，将所述TWS耳机3收纳于所述充电座2内以及TWS耳机3内置电池的电量低于设定值的需充电信息传送给所述值班处理器。
值班处理器，收到所述的需充电信息并通过电压输入检测电路确认USB接口58无外接电源时，向耳充开关模块和电流流向转换模块分别发出打开充电开关和使电流流动方向切换为向TWS耳机3方向输出的指令。
耳充开关模块，接到值班处理器发出的打开充电开关的指令后，向耳充电源管理模块发出接通所述供电电池7与电流流向转换模块通道的指令，此时，供电电池7输出的电流经耳充电源管理模块、电流流向转换模块流入充电座2为放置其中的TWS耳机3充电。
三、可实现的其它功能
1、路由功能
如图7所示，核心处理器内置一个4G模块，插入SIM卡即可实现接收基站信号，进行上网。
即其可当作随身路由器，分享手机号码带来的网络信号。
该多媒体适配机配合4G网络及TWS耳机3，可以方便使用到网络中音频信息及外置存储卡中的音频信息
2、录音功能
如图8所示，核心处理器对模拟信号的采样、编码将模拟信号通过数模转换器转换为数字信号，并进行一定的压缩后进行存储。
模拟信号通过MIC56进行接收，模拟信号的采样、编码由核心处理器完成。完成的数字信号通过存储卡进行存储(核心处理器还自带内存，同样可以存储内容)，需要回放音视频内容时，通过核心处理器的解码功能，可以从外置存储卡或内存中读取需要回放的内容，通过显示屏4播放。
回放内容可以通过蓝牙连接经TWS耳机3或内置的SPK模块进行播放。
3、存储功能
如图9所示，通过USB接口58与外置的电脑等设备进行数据交换并将接收到的数据信息存放于核心处理器的内存中或者存放在外接存储卡中。
核心处理器可通过所述的显示屏4清楚显示所存放的数据信息和相关目录。
4、节能功能
通过核心处理器与值班处理器的配合，可以实现能耗功率的控制。
当需要体现网络功能、显示功能、耳机收听功能时，核心处理器用电，而值班处理器、耳机充电路和供电电池7的充电进入待机状态。
当完成对耳机和供电电池7以及对外充电时，值班处理器用电，而核心处理器 处于待机状态。
5、功能切换
机壳上设置多个按键(包括硬按键和触摸按键)，通过按键操作，可以很轻松切换至不同的工作状态。如在显示屏4、TWS耳机3、SPK之间进行切换。
6、游戏功能
通过机壳上的显示屏4和实体按键可以转化为游戏机，配合耳机实现游戏功能。
