The working basic principle of the relocating coil mic is to try using a persons speech to vibrate the diaphragm from the air, and then the coil winding in the diaphragm and also the magnet surrounding the shifting coil mic develop a magnetic field reducing produce a fragile recent.

The working theory of the  conference microphone is to vibrate the diaphragm with the human speech throughout the atmosphere, so that the range in between the top diaphragm and also the lower metal steel dish changes, so that the capacitance modifications along with the recent impedance is actually created.
