How do microphones work? I just do not get it.
In: 85
There are two main types of microphone, broadly speaking: Condenser and Dynamic.
In a dynamic microphone, the sound captured ‘wobbles’ a magnet up and down a coil. An electrical signal is created by this movement that copies the ‘shape’ of the sound the same way a camera captures the shape of what’s in front of it.
In a condenser microphone the same effect is achieved with a super thin sheet of metal placed really close to another sheet of metal. As the sound captured ‘wobbles’ the thin sheet of metal, it gets closer and farther from the second sheet of metal. This can be turned into an electrical signal that looks like the ‘shape’ of the sound.
