摘要： A communications system includes a root node (14R); and a plurality of nodes (14) in communication with the root node (14R), the plurality of nodes (14) defining a mesh network; and the root node (14R) being configured to: determine a time delay to each node (14) of the plurality of nodes (14); transmit audio data to the plurality of nodes (14), the plurality of nodes (14) being configured to produce audio corresponding to the audio data; and transmit a delay code to the plurality of nodes (14), each of the plurality of nodes (14) being configured to produce the audio corresponding to the audio data at a time corresponding to the delay code.
