Microphone sensor module applied to A2B

The utility model relates to the technical field of microphone sensors, in particular to a microphone sensor module applied to A2B. Wherein the A2B module chip is integrated with an A2B transceiver, the two accessory circuits are used for power supply, signal and control management, a pin VDD in the digital microphone is connected to a VDD port of the A2B module chip, and power is supplied through the A2B module chip; a pin CLK in the digital microphone is connected with a BCLK clock of the A2B transceiver, the BCLK clock of the A2B transceiver is provided by a controller of the A2B module chip through a bus, and a pin OUT in the digital microphone is connected with a DRX signal input of the A2B transceiver; an AP pin and an AN pin of the A2B transceiver are connected to a CON-A double-wire connection port of the A2B module chip through an accessory circuit. The BP pin and the BN pin of the A2B transceiver are connected to the CON-B double-wire connection port of the A2B module chip through the other accessor
