Measurement of the performance of the head microphone (microphone MIC microphone)

February 26, 2023

1. Put the multimeter in the R*10 gear, and use the watch to intermittently touch the two output ends of the head coil. The sound film will make a “beep, bang” sound. If the sound is loud and hard, dry, it means the head performance. Poor; if the sound is softer and more delicate, it can be considered that the sound performance is better.
2. Adjust the multimeter to DC50uA or other smaller current block, use the test pen to connect the output ends of the coils at both ends, and use the mouth to blow the sound film to see the deflection angle of the hands. If the amplitude is large, the sensitivity of the head is high. Good performance. On the contrary, it is worse.
The above method can only make a preliminary judgment on the performance of the moving microphone microphone head. For the microphones used in different occasions, it is necessary to make a comparison to determine the pros and cons.
Note: The above test uses a pointer multimeter.
