Using microphones and their effects
Different types
·
Dynamic
o Diaphragm is attached to a coil
o When sound waves touch the diaphragm, the diaphragm vibrates
o This causes the coil to move on a magnet, producing electricity
o The current is then channelled from the microphone and along the wires
o It’s fairly sturdy
·
Condenser/capacitor
o Has 2 plates: front diaphragm plate and a back plate
o They are made of a light material which makes them more delicate
o When the diaphragm vibrates, the distance between the plates changes
o This also changes the capacitance
o The closer the plates, the increase of the capacitance and a charge of
current occurs
o The further away, a discharge current occurs
o Voltage for this microphone is required
o A battery is used to supply this voltage in the battery or by external
phantom power
