In the technical scheme disclosed in the embodiment, the microphones are respectively arranged on the inner side and the outer side of the tail gate, voice signals are collected through the inner side microphone when the tail gate is opened, and the voice signals are collected through the outer side microphone when the tail gate is closed.
Alternatively, the control module 300 may detect a state of the tailgate, detect whether the tailgate is currently in an open state or a closed state, and control the first microphone 100 or the second microphone 200 to receive the voice signal according to the state of the tailgate, for example, the control module 300 may control power supply of the first microphone 100 and the second microphone 200, and when the tailgate is open, power supply of the first microphone 100 is performed so that the first microphone 100 receives the voice signal and power supply of the second microphone 200 is not performed so that the second microphone 200 does not receive the voice signal, and when the tailgate is closed, power supply of the second microphone 200 is performed and power supply of the first microphone 100 is not performed; for another example, the control module 300 may control a communication bus of the first microphone 100 and a controller of the vehicle and a communication bus of the second microphone 200 and the controller of the vehicle, connect the first microphone 100 and the controller of the vehicle when the tailgate is opened, and disconnect the communication bus of the second microphone 200 and the controller of the vehicle.

Specifically, the power supply includes an anode and a cathode, the first microphone 100 is connected to any one of the anode and the cathode, the switch element 310 is connected to the other of the anode and the cathode, and the second microphone 200 is connected in a similar manner, so that when the tailgate is in an open state, the connection between the switch element 310 and the first microphone 100 is used to connect a path between the power supply and the first microphone 100, the power supply supplies power to the first microphone 100, the first microphone 100 can receive a voice signal, and the connection between the switch element 310 and the second microphone 200 is avoided to disconnect the path between the power supply and the second microphone 200; when the tail gate is in the closed state, the connection between the switch element 310 and the second microphone 200 is used to open the path between the power supply and the second microphone 200, the power supply supplies power to the second microphone 200, the second microphone 200 can receive the voice signal, and the connection between the switch element 310 and the first microphone 100 is avoided, so as to open the path between the power supply and the first microphone 100, thereby controlling the first microphone 100 or the second microphone 200 to receive the voice signal.
Alternatively, the state of the tailgate may be actively detected by a sensor while the switching element 310 is controlling the path between the power source and the first microphone 100, and the path between the power source and the second microphone 200. Of course, the switching element 310 may be driven by the closing and opening of the tailgate to perform the control of the path between the power supply and the first microphone 100 and the control of the path between the power supply and the second microphone 200.

Alternatively, in order to save the volume of the switching element 310 and reduce the occupied space, the first fixed electrode 313 and the second fixed electrode 314 may be shaped as ring-shaped electrodes as shown in fig. 2, and the common electrode 312 is located between the first fixed electrode 313 and the second fixed electrode 314, the first position is a position when the common electrode 312 abuts against the first fixed electrode 313, and the second position is a position when the common electrode 312 abuts against the second fixed electrode 314. The common electrode 312 is sleeved on the movable member 315, the elastic member 316 is directly connected to the movable member 315, or the elastic member 316 is indirectly connected to the movable member 315 through the common electrode 312, because the first fixed electrode 313 and the second fixed electrode 314 are ring-shaped electrodes, the movable member 315 can pass through the hollow area of the first fixed electrode 313 and protrude out of the end surface of the housing 311, and the elastic member 316 can pass through the hollow area of the second fixed electrode 314 and be connected to the housing 311, so that the occupied space of the switching element 310 can be reduced as much as possible without affecting the movement of the movable member.
