其中，操作系统模块，运行智能操作系统，该系统不仅可以采用传统电视芯片或OTT盒子芯片，也可以搭载手机、平板电脑类电子产品的高性能芯片，通过芯片的跨平台使用，可以提升系统性能，为用户带来更优质的使用体验，其中，OTT的英文全称为Over The Top，指通过互联网向用户提供各种应用服务。
较佳的，控制单元112中还可以包括连接操作系统模块的无线传输模块，实现与外部设备的无线通信。对于无线传输模块的具体种类形式，本发明实施例也不做具体限定，可以为WiFi模块，也可以为蓝牙模块等其 它种类形式的无线传输模块。
具体实施时，若音响系统11和显示系统12之间通过控制总线连接，图5中的输出单元113可以如图6所示，包括总线输出接口，通过该总线输出接口发送控制指令和预设格式的图像数据。
较佳的，输出单元113中还可以包括光纤输出接口，控制单元112通过该光纤输出接口与外部设备连接。
具体实施时，图5中的扬声器单元114可以如图6所示，包括左声道扬声器模块和右声道扬声器模块。

考虑到产品未来升级换代以及维修便利性，控制单元112可以以插接的形式与音响系统11中的其它单元相连，并且可以在中心腔体71中，通过结构设计让控制单元的插拔更为轻松。
需要说明的是，上述音响系统11的具体实现方式仅为示例，在本发明的其它具体实施例中，音响系统11也可以采用其它方式实现，在此不再进行举例详述。
进一步的，显示系统12如图8所示，具体可以包括第三信号输入单元121、图像处理单元122和显示单元123，其中：
第三信号输入单元121，接收预设格式的图像数据；若音响系统11和显示系统12之间通过控制总线连接，第三信号输入单元121可以包括总线输入接口，通过该总线输入接口接收预设格式的图像数据；
