Intelligent microphone array module for directional monitoring communication

Abstract

The invention discloses an intelligent microphone array module for directional monitoring communication. The intelligent microphone array module comprises a central microphone and a control module, and further comprises a first annular microphone array, a second annular microphone array, a third annular microphone array and a fourth annular microphone array which are annularly distributed from outside to inside in sequence by adopting the central microphone as the circle center. Through mixed design of the annular microphone arrays and linear microphone arrays, the intelligent microphone arraymodule is suitable for various scenes; the first annular microphone array, the second annular microphone array, the third annular microphone array and the fourth annular microphone array form four gears, the flexibility and adaptability of the intelligent microphone array module are improved, good gain benefits and spatial resolution benefits can be adjusted, and good balance can be reached; andcoordination command dispatching can be conducted on the microphone arrays according to the sound source position, microphones are controlled to automatically adjust the direction so as to achieve intelligent orientation, and the pickup quality of the microphones is further improved remarkably through combination of the microphone arrays and enhancement and noise reduction modules.

Description

technical field [0001] The invention relates to the technical field of microphones, in particular to an intelligent microphone array module for directional monitoring communication. Background technique [0002] The gain and spatial resolution of the microphone array are affected by the distance between the microphones. The larger the distance between the microphones, the greater the gain, but the lower the spatial resolution. At present, the commonly used microphone arrays are divided into linear array model microphone array, circular array model microphone array and stereo model microphone array. More information is collected, but the signal-to-noise ratio is reduced while the effective signal is less likely to be lost. The directivity of the linear array model microphone array is very good, and the coverage can be increased by using the line scan method, but at the same time, the amount of calculation is increased. [0003] Multiple microphones can be used to enhance or...
