1. Installation Position
The microphone head needs to be close to the sound source to make the sound received by the microphone head clearer, while avoiding interference from other noises as much as possible.
2. Signal Processing
The signal output by the microphone is relatively weak and needs to be processed through amplifiers or other operations to meet subsequent requirements.
3. Anti-Electromagnetic Interference
The electronic environment inside the car is complex, and the layout of the microphone circuit needs to shield electromagnetic interference to ensure the purity of the signal.
