请参照图1和图2，图1为本发明提供的一种音箱的结构示意图，图1中以高音扬声器4的个数为2为例，图2为本发明提供的一种双端子低音扬声器的结构示意图。
该音箱包括壳体1和设置于壳体1内的处理模块2、1个双端子低音扬声器3和2N个高音扬声器4，N为正整数；
处理模块2的左声道高音输出端与N个高音扬声器4的输入端连接，右声道高音输出端与另外N个高音扬声器4的输入端连接，左声道低音输出端与双端子低音扬声器3的左声道输入端连接，右声道低音输出端与双端子低音扬声器3的右声道输入端连接，用于控制高音扬声器4对左声道高频音源信号和右声道高频音源信号进行重放，控制双端子低音扬声器3对左声道低频音源信号和右声道低频音源信号进行重放。
具体地，本申请中，音箱包括壳体1，壳体1内设置有处理模块2、1个双端子低音扬声器3和2N个高音扬声器4。处理模块2输出左声道高频音源信号至N个高音扬声器4，输出右声道高频音源信号至另外N个高音扬声器4。处理模块2还输出左声道低频音源信号至双端子低音扬声器3的左声道输入端，输出右声道低频音源信号至双端子低音扬声器3的右声道输入端。可见，本申请虽然表面上看是一个低音扬声器搭配2N个高音扬声器4组成2.1系统，但是由于该低音扬声器为双端子低音扬声器3，可以同时输入左声道低频音源信号和右声道低频音源信号，因此，其本质上可以看作是2.2系统。具体地，双端子低音扬声器3可以包括振膜和驱动单元，驱动单元用于驱动振膜振动，其中，驱动单元包括音圈及其对应地的磁路单元，驱动单元设置有两个端子，也即双端子低音扬声器3的左声道输入端和右声道输入端。
此外，这里的高音扬声器4的数量可以为2个且只朝向一个方向；也可以为2个但是壳体1可旋转，使得高音扬声器4的朝向始终朝向用户。此外，高音扬声器的数量可以为4个及以上，围在壳体1的一周，使得无论用户在音箱的哪个位置，均有高音扬声器4朝向用户。
可见，本申请中，由于双端子低音扬声器3包括左声道输入端和右声道输入端，具体可参照图2中侧面，可以同时输入左声道低频音源信号和右声道低频音源信号，因此，无需对输入至双端子低音扬声器3的左右声道低频音源信号进行编码，从而保留了原左右声道低频音源信号的完整性，保证了音效。此外，由于只用一个低音扬声器，而声音通道数量并未改变，降低了功耗且保证了音效。此外，双端子可以降低低音扬声器的低频共振频率，进而可以使得和高音扬声器4配合时两者的分频点可以设的较低，利于音箱的低频的重放，低频音效的展示更为充分。
在上述实施例的基础上：
作为一种优选地实施例，音箱还包括与处理模块2连接的显示屏5，壳体1包括主机壳体和与主机壳体连接的显示屏壳体，显示屏壳体内设置有显示屏5。
具体地，请参照图3和图4，图3为本发明提供的一种音箱的正视图，图4为本发明提供的一种音箱的侧视图。
音箱还包括与处理模块2连接的显示屏5，处理模块2除了控制双端子低音扬声器3和高音扬声器4发声，还可以控制显示屏5对视频、歌曲对应地图像进行显示，便于用户在听音的同时还观看与音频配合的影像，提高了用户体验。
显示屏壳体上还可以设置有按键，用来控制整个音箱的开关机、音量和屏幕的开关等。
显示屏5可以但不仅限为液晶显示屏，具体类型可以根据实际情况来定。
作为一种优选地实施例，高音扬声器4设置于主机壳体或者显示屏壳体上。
具体地，在实际应用中，高音扬声器4可以设置在主机壳体上，也可以设置在显示屏壳体上，例如，显示屏5位于主机壳体的前部，高音扬声器4 设置于主机壳体的前部且高音扬声器4的振膜朝前，双端子低音扬声器3设置于主机壳体的上部且双端子低音扬声器3的振膜朝上；或者，双端子低音扬声器3设置于主机壳体的底部且双端子低音扬声器3的振膜朝下。
本申请中，双端子低音扬声器3可以设置于主机壳体的上部且双端子低音扬声器3的振膜朝上或者设置于主机壳体的底部且双端子低音扬声器3的振膜朝下，这样便于将低音效果最大程度扩散到四面八方。两个高音扬声器4也设置在主机壳体的前部，振膜朝前，其中，这里的超前可以指的是高音扬声器4的高度可以低于低于显示屏壳体的下边缘，由于用户通常站在音箱的前部观看显示屏5上的视频，因此，该种设置方式便于高音扬声器4向前部发声，提高了用户体验。
又例如，显示屏5位于主机壳体的前部，高音扬声器4设置于显示屏壳体上且高音扬声器4的振膜朝前，双端子低音扬声器3设置于主机壳体的上部且双端子低音扬声器3的振膜朝上；或者，双端子低音扬声器3设置于主机壳体的底部且双端子低音扬声器3的振膜朝下。
本申请中，双端子低音扬声器3可以设置于主机壳体的上部且双端子低音扬声器3的振膜朝上或者设置于主机壳体的底部且双端子低音扬声器3的振膜朝下，这样便于将低音效果最大程度扩散到四面八方。两个高音扬声器4设置在显示屏壳体的前部，振膜朝前，由于用户通常站在音箱的前部观看显示屏5上的视频，因此，该种设置方式便于高音扬声器4向前部发声，提高了用户体验。此外，由于高音扬声器4设置于显示屏壳体上，主机壳体上只有一个双端子低音扬声器3，可以把声腔做的更大，提高效果，即便不把声腔做的更大，因为无需预留安装高音扬声器4的位置，也可以减小主机壳体体积。
需要说明的是，两个高音扬声器4可以但不仅限为设置于显示屏5的左右两侧。
作为一种优选地实施例，显示屏壳体可旋转和/或可滑动的设置于主机壳体上；
和/或，还包括底座，主机壳体可旋转的设置于底座上。
具体地，本申请中，显示屏壳体可滑动的设置于主机壳体上，例如主机壳体的水平方向上设置有滑轨，音箱还包括与显示屏壳体连接的滑动模块， 这样，显示屏壳体便可以围绕着主机壳体水平滑动。还可以采用其他方式使得显示屏壳体滑动，由于仅屏幕滑动，使用的动力机构小，如果手动，使用体积较小、强度小的滑轨即可；如果电动，使用小功率电机即可。
显示屏壳体还可以可旋转的设置于主机壳体上，例如显示屏壳体可以通过铰接的方式与主机壳体连接，或者通过铰接的方式与主机壳体上的滑动模块连接，当然，还可以通过驱动模块的方式进行驱动，这样显示屏壳体便可以在主机壳体上上下旋转。
音箱还可以包括底座，主机壳体可旋转的设置于底座上，例如具体可以通过电机驱动主机壳体旋转。
作为一种优选地实施例，还包括：
与显示屏壳体和/或主机壳体连接的驱动模块；
处理模块2与驱动模块连接，还用于通过驱动模块控制显示屏壳体旋转和/或滑动，和/或主机壳体旋转。
本申请中，音箱还包括驱动模块，处理模块2能够通过驱动模块控制显示屏壳体旋转和/或滑动，和/或主机壳体旋转。这里的驱动模块可以为滑轨及与滑轨配合的滑动模块等，还可以为电机等，本申请在此不作特别的限定，根据实际情况来定。
具体地，主机壳体的水平方向上设置有滑轨，滑动模块可以带动着显示屏壳体也即显示屏5在滑轨上水平滑动。具体地，处理模块2可以控制滑动模块带动着显示屏壳体在滑轨上水平滑动，这样，便可以使得屏幕一直面对用户，中高频的发声方向永远正对用户，尽可能地规避由于中高频指向性强导致用户听到的中高频声振特性较差的问题。
需要说明的是，处理模块2可以基于用户通过终端发送的调节指令控制滑动模块，也可以是处理模块2根据音箱上的传感器采集到的数据自动控制滑动模块，具体采用哪种方式本申请在此不作特别的限定，根据实际情况来定。
作为一种优选地实施例，音箱还包括：
设置于主机壳体上的传感器；
处理模块2还用于在基于传感器采集的数据确定传感器采集区域内有用户存在且显示屏5的朝向方位和用户的方位不一致时，通过驱动模块控制显 示屏壳体旋转和/或滑动，和/或主机壳体旋转，使得显示屏5的朝向方位和用户的方位一致。
本申请中，音箱还包括设置于主机壳体上的传感器。传感器会对音箱周围的采集区域内进行数据采集，处理模块2在接收到传感器采集的数据后，基于传感器采集的数据判断传感器采集区域内是否有用户存在，若有用户存在，则判断显示屏5的朝向方向和用户的方位是否一致，若是，则保持显示屏5及主机壳体的位置不变，否则，控制驱动模块工作，例如通过驱动模块控制显示屏壳体旋转和/或滑动，和/或主机壳体旋转，使得显示屏5的朝向方位和用户的方位一致。
需要说明的是，这里的传感器可以为多个，可以设置水平均匀设置在主机壳体的四周，处理模块2基于至少两个传感器采集的数据来确定用户的方位，而显示屏5的朝向方位对于处理模块2来说也是可以得到的，基于此，便可以判断显示屏5的朝向方位和用户的方位是否一致。
可见，通过该种方式可以使得屏幕一直面对用户，中高频的发声方向永远正对用户，提高了音箱的音质。
作为一种优选地实施例，传感器为接近检测传感器。
作为一种优选地实施例，接近检测传感器为超声波传感器或者激光雷达传感器或者红外TOF(Time of flight，飞行时间)接近传感器。
具体地，超声波传感器具有方向性好的优点，激光雷达传感器具有精度高，量程大，抗光、电干扰能力强的优点，红外TOF接近传感器能够在短时间内准确地检测物体，并且不受湿度，气压和温度的影响。当然，这里还可以采用其他类型的接近传感器，本申请在此不作特别的限定。
作为一种优选地实施例，传感器为摄像头。
具体地，摄像头对音箱周围进行拍摄，得到图像数据，处理模块2基于图像数据便可判定音箱周围是否有用户，若有，则基于图像数据确定用户的方位。可见，通过该种方式可以确定音箱周围是否有用户，以便后续对显示屏5的朝向进行调整。
作为一种优选地实施例，处理模块2包括处理器、低频音效处理芯片和高频音效处理芯片，
处理器用于输出原始音源信号；
低频音效处理芯片，用于对原始音源信号进行功率放大处理并滤除高频音源信号，输出左声道低频音源信号及右声道低频音源信号至双端子低音扬声器3，以控制双端子低音扬声器3对左声道低频音源信号和右声道低频音源信号进行重放；
高频音效处理芯片，用于对原始音源信号进行功率放大并滤除低频音源信号，输出左声道高频音源信号至1个高音扬声器4，输出右声道高频音源信号至另一个高音扬声器4，以控制2个高音扬声器4对左声道高频音源信号和右声道高频音源信号进行重放。
考虑到现有技术的音箱中通常仅采用一个音效处理芯片，为了避免由于传输线的长短不一造成的低音扬声器和高音扬声器4的延时问题，现有技术中，扬声器的距离不能分开太远。
为了解决上述技术问题，本申请中，音效处理芯片包括低频音效处理芯片和高频音效处理芯片，具体地，低频音效处理芯片在接收到原始音源信号进行功率放大处理并滤除高频音源信号，输出左声道低频音源信号及右声道低频音源信号至双端子低音扬声器3，以控制双端子低音扬声器3对左声道低频音源信号和右声道低频音源信号进行重放。高频音效处理芯片在接收到原始音源信号后，对原始音源信号进行功率放大并滤除低频音源信号，输出左声道高频音源信号至1个高音扬声器4，输出右声道高频音源信号至另一个高音扬声器4，以控制2个高音扬声器4对左声道高频音源信号和右声道高频音源信号进行重放。
可见，本申请中，双端子低音扬声器3和高音扬声器4是通过不同的音效处理芯片分别控制的，不存在一个音效处理芯片控制控制低音扬声器和高音扬声器4的导致的信号在传输线里传输造成的延时问题，进一步保证了音箱的音效。
本申请还提供了一种系统，包括如上述所述的音箱。
对于本申请提供的音箱的介绍请参照上述音箱实施例，本申请在此不再赘述。
此外，这里的系统可以为音箱+电视的组合，或者为音箱+投影的组合，音箱用于播放电视/投影的声音，即家庭影院。这里的系统还可以为音箱+其 他设备，通过音箱控制其他设备，即智能家居。这里的系统还可以为包括音箱的展厅、体验厅等，本申请在此不做特别地限定。
需要说明的是，在本说明书中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其他实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
