S1、获取空间的空间位置信息；所述步骤S1包括子步骤S11-S13：S1. Obtain spatial location information of the space; the step S1 includes sub-steps S11-S13:
S11、获取空间的音频发生设备及乘坐装置的空间位置信息；例如，空间为客厅，音频发生设备为客厅内的电视机，乘坐装置为客厅内的沙发。获取该客厅的长宽高以及电视机及沙发的位置信息，或者获取该客厅的平面图纸及客厅的天花板高度等等。S11. Acquire an audio generating device of the space and spatial position information of the riding device; for example, the space is a living room, the audio generating device is a television in the living room, and the riding device is a sofa in the living room. Get the length and width of the living room and the location information of the TV and the sofa, or get the floor plan of the living room and the ceiling height of the living room.
S12、将所述音频发射装置1邻近设置于所述音频发生设备以接入音频信息；例如，音频发射装置1放置于电视机上方，从而可使调频传输信道良好。也可以根据客户需要摆放，音频发射装置1只需通过连接上电视机的输出音频即可；若音频发生设备为手机，音频发射装置1通过音频蓝牙插座107连接预设的蓝牙模块，再通过蓝牙模块与该手机建立蓝牙连接，通过蓝牙传输音频信息，即手机发出蓝牙信号传递至蓝牙模块，蓝牙模块插接音频蓝牙插座107，从而使该蓝牙信号传输至音频发射装置1。S12. The audio transmitting device 1 is disposed adjacent to the audio generating device to access audio information; for example, the audio transmitting device 1 is placed above the television, so that the FM transmission channel can be made good. It can also be placed according to customer needs. The audio transmitting device 1 only needs to connect the output audio of the TV set; if the audio generating device is a mobile phone, the audio transmitting device 1 connects to the preset Bluetooth module through the audio Bluetooth socket 107, and then passes The Bluetooth module establishes a Bluetooth connection with the mobile phone, and transmits audio information through Bluetooth, that is, the mobile phone sends a Bluetooth signal to the Bluetooth module, and the Bluetooth module plugs into the audio Bluetooth socket 107, thereby transmitting the Bluetooth signal to the audio transmitting device 1.
S13、依据所述音频发射装置1的位置计算多个所述调频音响装置2的位置设置范围。一般的客厅都处于音频发射装置1的调频发射范围内，如此，多个所述调频音响装置2的位置设置范围即为该客厅内的任何位置。若客厅因为太大而导致音频发射装置1覆盖不了整个客厅，此时需要计算音频发射装置1的发射范围，一般为以音频发射装置1的位置为圆心，发射最长的距离为半径的圆形，多个所述调频音响装置2的位置设置范围即为该圆形区域。S13. Calculate a position setting range of the plurality of FM audio devices 2 according to the position of the audio transmitting device 1. The general living room is in the FM transmission range of the audio transmitting device 1, and thus, the position setting range of the plurality of the FM speakers 2 is any position in the living room. If the living room is too large, the audio transmitting device 1 cannot cover the entire living room. At this time, it is necessary to calculate the transmission range of the audio transmitting device 1, which is generally a circle with the position of the audio transmitting device 1 as the center and the longest distance as the radius. The position setting range of the plurality of FM sounding devices 2 is the circular area.
S2、依据所述空间位置信息将多个所述调频音响装置2设置在所述空间的底面和/或顶面和/或侧面。所述步骤S2包括子步骤S21-S22：S2. Depending on the spatial position information, a plurality of the FM audio devices 2 are disposed on a bottom surface and/or a top surface and/or a side surface of the space. The step S2 includes sub-steps S21-S22:

S22、判断所述设置位置是否处于所述位置设置范围之内，若是，则依据 所述设置位置安装多个所述调频音响装置2，若否，则重新计算所述多声道环绕立体声系统100的设置位置。一般地，只要音频发射装置1的调频发射范围可以覆盖整个客厅，则无需重新计算所述多声道环绕立体声系统100的设置位置。若所述多声道环绕立体声系统100的设置位置超出了音频发射装置1的调频发射范围，才需重新计算所述多声道环绕立体声系统100的设置位置。S22. Determine whether the set position is within the location setting range, and if yes, according to The plurality of FM audio devices 2 are installed in the set position, and if not, the set positions of the multi-channel surround sound system 100 are recalculated. In general, as long as the FM transmission range of the audio transmitting device 1 can cover the entire living room, it is not necessary to recalculate the setting position of the multi-channel surround sound system 100. If the set position of the multi-channel surround sound system 100 exceeds the FM transmission range of the audio transmitting device 1, the set position of the multi-channel surround sound system 100 needs to be recalculated.
优选的，所述安装方法还包括步骤S3：Preferably, the installation method further includes step S3:
S3、在所述空间的顶面开设多个用于安装多个所述调频音响装置2的开孔。例如，调频音响装置2为筒灯，此时只需在客厅的吊顶内开设多个用于安装多个筒灯的开孔，把该筒灯安装在该开孔位置即可。如此，不仅利用了筒灯的照明功能，还在筒灯内加设了音响功能，丰富了筒灯的功能，并且由于筒灯一般为覆盖整个客厅，极易达到多声道环绕立体声的效果。S3. A plurality of openings for mounting a plurality of the FM audio devices 2 are disposed on a top surface of the space. For example, the FM audio device 2 is a downlight. In this case, it is only necessary to open a plurality of openings for mounting a plurality of downlights in the ceiling of the living room, and the downlight can be installed in the opening position. In this way, not only the lighting function of the downlight is utilized, but also the sound function is added in the downlight, which enriches the function of the downlight, and since the downlight generally covers the entire living room, it is easy to achieve the effect of multi-channel surround sound.
优选的，所述安装方法还包括步骤S4：Preferably, the installation method further includes step S4:
S4、在所述空间的侧面设置有多个用于安装多个所述调频音响装置2的固定装置。例如，在客厅的墙壁上设置多个用于安装多个所述调频音响装置2的固定装置，固定装置可以固定比较沉重的音响喇叭207，如此，不仅节约了客厅的空间，还保证了每一个音响喇叭207的音质，使多声道环绕立体声的效果更佳。S4.

For example, a plurality of fixing devices for mounting a plurality of the FM audio devices 2 are disposed on the wall of the living room, and the fixing device can fix the relatively heavy acoustic speakers 207, thereby saving not only the space of the living room but also each of the living rooms. The sound quality of the horn 207 makes multi-channel surround sound better.
