Disclosed is a distributed microphone array. The array comprises: a plurality of distributed microphone array nodes, wherein each microphone array node is provided with one or a plurality of microphone audio acquisition modules; and the microphone array node is connected to an external signal processing unit by means of wireless network communication, and uploads an unprocessed audio signal or an audio signal which has undergone simple signal processing on the array node to the signal processing unit. In the present invention, all the wireless microphone array nodes distributed in a wireless network form a large microphone array. In a wireless microphone array, microphone signal acquisition and transmission are based on a wireless type, and the distribution of microphones is no longer limited by a physical dimension or a cabling connection, so that the distribution of a significant amount of microphones can be achieved, and the distance between the microphones and the coverage area of the microphone array can be greatly increased.
