Optionally, part of the microphones may further convert the obtained analog signals into digital sampled signals.

2) Microphone array

Since a microphone usually can only collect sound signals at one point, and the collection performance and the functions that can be achieved are relatively limited, in the related art, in order to improve the performance and the functions of sound collection, a scheme of respectively arranging a plurality of microphones at different spatial positions to form a microphone array is proposed. The sound signal processing chip on the microphone circuit board is used for carrying out centralized processing on sound signals respectively collected by a plurality of microphones in the microphone array, so that the sound collection performance can be improved, and new functions can be expanded. For example, in an intelligent device with a speech recognition function, a microphone array composed of a plurality of microphones can enhance the speech of a target user, suppress noise in the environment, and locate the direction of a sound source, thereby finally improving the speech recognition performance in a speech interaction (especially far-field speech interaction) scene.
