应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步 讨论。
本申请实施例提供了一种车载K歌***，如图1所示，至少两个多媒体主机以及与每一多媒体主机一一对应的显示屏。
需要说明的是，图1中以车载K歌***包括三个多媒体主机以及与该三个多媒体主机一一对应的显示屏为例进行示出。其中，三个多媒体主机分别记为多媒体主机1、多媒体主机2以及多媒体主机3，以及与之对应的显示屏依次分别记为显示屏1、显示屏2以及显示屏3。
对于任一多媒体主机，包括存储器和处理器。其中：
存储器用于存储计算机指令；
处理器用于从存储器中调用计算机指令，以执行如下述方法实施例提供的任一项的车载K歌***的控制方法。
在一个实施例中，如图1所示，车载K歌***还包括：功率放大器、扬声器以及至少一个麦克风，其中：
任一麦克风与至少两个多媒体主机中的第一多媒体主机连接，功率放大器连接在第一多媒体主机与扬声器之间；
任一麦克风用于接收人声音频；
功率放大器用于对第一多媒体主机输出的混音音频进行放大并输出至扬声器；
扬声器用于播放放大后的混音音频。
需要说明的是，在本申请实施例中，第一多媒体主机为至少两个多媒体主机中的一个与车辆的扬声器和麦克风连接的多媒体主机。第二多媒体主机为至少两个多媒体主机中的除第一多媒体主机外的多媒体主机。基于此可知，图1中的多媒体主机1为第一多媒体主机，多媒体主机2和多媒体主机3均为第二多媒体主机。
在一个实施例中，如图1所示，麦克风与第一多媒体主机的连接，可以为无线连接，也可以为无线连接。
第二多媒体主机与第一多媒体主机之间分别通过音频通道连接。
以及，每一多媒体主机两两之间通过车辆信息交互通道连接。
可以理解的是，多媒体主机与匹配的显示屏之间电连接。以及，第一 多媒体主机与功率放大器之间、功率放大器和扬声器之间通过音频通道连接。
可以理解的是，在车载K歌***包括至少两个多媒体主机以及与每一多媒体主机一一对应的显示屏的情况下，可在车辆的前排和后排分别安装至少一个多媒体主机以与之相匹配的显示屏。
本申请实施例提供了一种车载K歌***的控制方法。该方法应用于车载K歌***中的任一多媒体主机。如图2所示，本申请实施例提供的车载K歌***的控制方法包括如下S1100-S1300：
S1100、接收K歌应用的开启指令。
在本申请实施例中，多媒体主机中安装有K歌应用。该K歌应用为多媒体主机从云端预先下载的第三方应用。
在本申请实施例中，多媒体主机控制对应的显示屏显示K歌应用的图标。用户可点击该K歌应用的图标，以向多媒体主机发送K歌应用的开启指令。在此基础上，多媒体主机基于用户的点击K歌应用的图标的操作，接收到K歌应用的开启指令。
S1200、根据开启指令，控制匹配的显示屏显示K歌应用的界面。
在本申请实施例中，多媒体主机在接收到K歌应用的开启指令后，响应于该开启指令，控制匹配的显示屏显示K歌应用的界面。
在本申请实施例中，在执行S1200之后，用户可对K歌应用的界面进行操作，以实现K歌。
在本申请实施例中，由于车载K歌***包括至少两个多媒体主机以及与每一多媒体主机一一对应的显示屏，因此，可在车辆的前排和后排分别安装至少一个多媒体主机以与之相对应的显示屏。
在一个实施例中，如图3所示，可在车辆的前排、后排左侧以及后排右侧分别安装一个多媒体主机以及与之相对应的显示屏。每一多媒体主机可执行上述S1100和S1200的步骤。这样，后排用户可基于自身的位置选择后排左侧或后排右侧的显示屏进行K歌。这也就是说，本申请实施例提供的车载K歌***的控制方法可便于后排用户实现K歌需求。这提高了用户的用车体验。
S1300、控制第一多媒体主机输出混音音频。
其中，第一多媒体主机为至少两个多媒体主机中的一个与车辆的扬声器和麦克风连接的多媒体主机。
需要说明的是，本申请实施例对上述S1300的具体实现不做限定。
在本申请实施例中，通过控制第一多媒体主机输出混音音频，可实现仅由车载K歌***中的第一多媒体主机输出混音音频，而无需由第二多媒体主机输出混音音频。
进一步的，功率放大器对第一多媒体主机输出的混音音频进行放大并输出至所述扬声器。扬声器播放放大后的混音音频。基于此可知，本申请实施例提供的车载K歌***仅需向第一多媒体主机配置功率放大器、扬声器以及麦克风。这降低了车载K歌***的硬件成本。这也就是说，本申请实施例提供的车载K歌***的控制方法为降低车载K歌***的硬件成本提供基础。
在本申请实施例中，提供了一种车载K歌***的控制方法，车载K歌***包括：至少两个多媒体主机以及与每一多媒体主机一一对应的显示屏，方法应用于任一多媒体主机，包括：接收K歌应用的开启指令；根据开启指令，控制对应的显示屏显示K歌应用的界面；控制第一多媒体主机输出混音音频；其中，第一多媒体主机为至少两个多媒体主机中的一个与车辆的扬声器和麦克风连接的多媒体主机。通过本申请实施例，一方面，可便于后排用户实现K歌需求，这提高了用户的用车体验。另一方面，为降低车载K歌***的硬件成本提供基础。
在本申请的一个实施例中，上述S1300可具体通过如下S1310和S1320来实现：
S1310、在多媒体主机为第二多媒体主机的情况下，根据针对于K歌应用的界面输入的播放指令，通过音频通道向第一多媒体主机发送与播放指令匹配的伴奏音频。
其中，第二多媒体主机为至少两个多媒体主机中的除第一多媒体主机外的多媒体主机。
在本申请实施例中，本申请实施例提供的车载K歌***的控制方法在 上述S1300之前还包括如下S1311：
S1311、接收针对于K歌应用的界面输入的播放指令。
在本申请实施例中，用户基于对应的显示屏所显示的K歌应用的界面，选中满足需求的K歌歌曲，以指示多媒体主机输出该K歌歌曲的伴奏音频。此时，多媒体主机接收到针对于K歌应用的界面输入的播放指令，并基于该播放指令输出伴奏音频。
在本申请实施例中，第二多媒体主机通过物理载体，该物料载体例如是线束，与第一多媒体主机连接。其中，物理载体用于提供音频通道。在多媒体主机为第二多媒体主机的情况下，多媒体主机在接收到播放指令后，根据针对于K歌应用的界面输入的播放指令，向第一多媒体主机发送与播放指令匹配的伴奏音频。
S1320、在多媒体主机为第一多媒体主机的情况下，接收人声音频以及伴奏音频，根据人声音频和伴奏音频，控制第一多媒体主机输出混音音频。
在本申请实施例中，在多媒体主机为第一多媒体主机的情况下，多媒体主机接收到的伴奏音频的来源包括如下两种情况。
第一种情况：基于上述S1310，从第二多媒体主机接收到的伴奏音频。
第二种情况：根据接收到的播放指令所确定的伴奏音频。
在本申请实施例中，用户通过与第一多媒体主机有线或无线连接的麦克风唱歌。麦克风接收用户的歌声并向第一多媒体主机发送对应的人声音频。基于此，第一多媒体主机接收到人声音频。
在本申请实施例中，在多媒体主机为第一多媒体主机的情况下，多媒体主机根据接收到的人声音频和伴奏音频，生成混音音频。
在本申请的一个实施例中，本申请实施例提供的车载K歌***的控制方法在上述S1200之后，还包括如下S1400和S1500的步骤：
S1400、接收第二类型操作指令。
其中，第二类型操作指令为针对K歌应用的操作指令。
在本申请实施例中，第二类型操作指令包括但不限于：搜歌、切歌、显示歌词、输入评论等中的至少一个。
S1500、执行第二类型操作指令。
在本申请实施例中，以第二类型操作指令为显示歌词为例，上述S1500的具体实现为：获取当前播放伴奏音频对应的歌词，并对其进行显示。
在本申请的一个实施例中，本申请实施例提供的车载K歌***的控制方法还可实现至少两个人的K歌。基于此，本申请实施例提供的车载K歌***的控制方法在上述S1100之后还包括如下S2100-S2500：
S2100、接收互联指令。
在本申请实施例中，多媒体主机提供互联应用。该互联应用可供多媒体主机选择其他多媒体主机，以实现互联。
在本申请实施例中，用户可点击互联应用的图标。多媒体主机检测到该互联应用的图标被点击后，响应该点击，接收互联指令。
S2200、根据互联指令，显示待互联多媒体主机标识。
在本申请实施例中，待互联多媒体主机为车载K歌***中，除接收互联指令的多媒体主机外的多媒体主机。
多媒体主机在接收到互联指令后，响应该互联指令，并将其他多媒体主机标识以列表或其他形式进行显示。
在一个实施例中，待互联多媒体主机的标识可通过待互联多媒体主机的方位表示。例如，后左、后右等。
S2300、接收选择指令。
在本申请实施例中，选择指令为用户选择待互联多媒体主机标识中的一个的操作。在多媒体主机检测到用户基于对应的显示屏输入的选择操作之后，确定接收到该选择指令。
S2400、根据选择指令，确定目标互联多媒体主机。
在本申请实施例中，多媒体主机响应于选择指令，并将选择指令对应的待互联多媒体主机标识所对应的多媒体主机作为目标互联多媒体主机。
S2500、基于多媒体主机与目标互联多媒体主机之间的无线连接，向目标互联多媒体主机投屏。
在本申请的一个实施例中，在多媒体主机确定目标互联多媒体主机之后，与目标互联多媒体主机建立无线连接。
在本申请的另一个实施例中，多媒体主机可在接收互联指令后，直接与每一待互联多媒体主机建立无线连接。这样可实现多媒体主机与目标互联多媒体主机预先连接，以使得多媒体主机可快速向目标互联多媒体主机投屏。
在本申请实施例中，多媒体主机仅向目标互联多媒体主机执行投屏。基于此，多媒体主机和目标互联多媒体主机可实现显示相同的内容。这样，使用多媒体主机的用户和使用目标互联多媒体主机的用户查看到相同的显示界面，以便使用多媒体主机的用户和使用目标互联多媒体主机的用户一起K歌。
在本申请的一个实施例中，本申请实施例提供的车载K歌***的控制方法还包括如下S2600：
S2600、在多媒体主机为目标互联多媒体主机的情况下，响应于投屏，输出投屏内容。
在本申请实施例中，在多媒体主机为目标互联多媒体主机的情况下，在多媒体主机被投屏的情况下，多媒体主机响应于该投屏的操作，输出投屏内容。在本申请实施例中，投屏内容包括投屏画面。
基于上述S2100-S2500，本申请实施例提供的车载K歌***的控制方法在上述S2500之后，还包括如下S2700和S2800：
S2700、接收第一类型操作指令。
在本申请实施例中，第一类型操作指令为除针对K歌应用的操作指令外的操作指令。
在本申请实施例中，第一类型操作指令可以为多媒体主机自带应用所提供的操作对应的指令，该多媒体主机自带应用例如是多媒体主机提供的互联应用。
在一个实施例中，第一类型操作指令可示例性为：调整麦克风音量、调整***音量、调整音效以及调整混响中的任一个或者多个。
S2800、执行第一类型操作指令，并将第一类型操作指令通过车辆信息交互通道输出。
在本申请的一个实施例中，车辆信息交互通道可示例性的为CAN通 信通道。
在本申请实施例中，车辆信息交互通道可将任两个多媒体主机连接起来。
在本申请实施例中，结合第一类型操作指令的定义可知，基于上述S2500中的投屏无法使得目标互联多媒体主机与接收第一类型操作指令的多媒体主机联动。因此，需将第一类型操作指令通过车辆信息交互通道通知给目标互联多媒体主机。
其中，目标互联多媒体主机与接收第一类型操作指令的多媒体主机联动指的是，目标互联多媒体主机跟随接收第一类型操作指令的多媒体主机，接收第一类型操作指令，并对第一类型操作指令进行响应。
在本申请实施例中，由于车辆信息交互通道传输信息速度快，因此，可基于车辆信息交互通道，将第一类型操作指令输出，以实现多媒体主机与目标互联多媒体主机之间的快速联动。
在上述S2800的基础上，本申请实施例提供的车载K歌***的控制方法还包括如下S2910和S2920：
S2910、在多媒体主机为目标互联多媒体主机的情况下，通过车辆信息交互通道接收第一类型操作指令，并执行第一类型操作指令。
在本申请实施例中，在多媒体主机为目标互联多媒体主机的情况下，此时，多媒体主机为了与发送第一类型操作指令的多媒体主机保持联动，需执行通过车辆信息交互通道接收的第一类型操作指令。
S2920、在多媒体主机为非目标互联多媒体主机的情况下，通过车辆信息交互通道接收并丢弃所述第一类型操作指令。
在本申请实施例中，由于任一多媒体主机均会接收到车辆信息交互通道发送的信息。因此，在多媒体主机为非目标互联多媒体主机的情况下，多媒体主机也会通过车辆信息交互通道接收到第一类型操作指令。
而在所述多媒体主机为非目标互联多媒体主机的情况下，此时，多媒体主机无需与发送第一类型操作指令的多媒体主机保持联动。因此，多媒体主机在通过车辆信息交互通道接收到第一类型操作指令后，对其丢弃，即不进行处理。
本申请实施例提供了一种车载K歌***，该车载K歌***包括至少两个多媒体主机以及与每一多媒体主机一一对应的显示屏。
对于任一所述多媒体主机400，如图4所示，包括：存储器410和处理器420，其中：
所述存储器410用于存储计算机指令；
所述处理器420用于从所述存储器中调用所述计算机指令，以执行如上述任一实施例提供的任一项所述的车载K歌***的控制方法。
