Abstract

本发明提供了一种声学级联系统的同步方法，其通过对声学级联的扬声器进行补偿，实现了扬声器播放内容的同步，包括步骤：主控设备打开麦克风并通知每个节点设备进行录音；主控设备扬声器播放声学信号S1，空闲P1时间；第i台节点设备Di接收声学信号S0，同时同步播放声学信号Si+2，并同步转发声学信号S0给第i+1台节点设备Di+1，直到最后一台节点设备Dn接收声学信号S0,同步播放声学信号Sn+2；把自身采集的音频数据发送到主控设备；计算每台设备所采集声学信号中声信号S1和对应回采信号起始时间之间的时间差；计算每台级联设备相对主控设备的线路传输时延；根据信号传输时延进行补偿实现播放内容同步。
