How Dynamic Mics Work

This video explains how a moving-coil dynamic microphone works. It is an excerpt from Roswell Pro Audio founder Matthew McGlynn's presentation at the annual Audio Symposium at the University of Michigan, February 2019.

Thank you Roswell audio! Excellent synopsis of how a dynamic mic works! Saving my pennies for a mini k47 pair...do you sell a dynamic mic?

[@RoswellProAudio]

Thanks, Jeremy! Roswell does not have any dynamic mics, although we are investigating some design possibilities. In the meantime, I'm happy to make recommendations for specific applications. Contact me at the RecordingHacks Forum: hac.kz/forum

One question
Does the movement of the voice coil within the magnetic field created by the magnet produce the current/audio signal ?

[@xenopis7862]

Yep, I think you're right. Just the basic electromagnetic theory you learn in highschool.
Whenever a conductor moves in the presence of a magnetic flux, a voltage is produced within the conductor.
