How a Michrophone and a Speaker Works and how does the sound travel through the air and cables! The original video was made in spanish by me (Eduardo Piñones) and I will be translating them
Wow, how fascinating ! Especially the last bit !! Many thanks for various creative videos on this channel. ps. More details of audio amplification (via BJT or MOSFET) would be much appreciated.
Praise God for how He made the laws of physics including electricity (a branch of physics) to work so these things are possible. These are dynamic speakers/microphones. There are (or there used to be) crystal speakers/earphones that can function in both ways too.
