Moving coil Microphone Flashcards
What are the 3 main components of a microphone
a diaphragm
a coil
a magnet
What two parts of the microphone can move and vibrate
diaphragm and coil
What does the coil moving and magnet not allow
Induced voltage produced
What does the microphone intially need to work (person)
vibrations in your throat to make a sound wave
What happens when a sound wave hits the diaphragm
it is made to vibrate
What happens to the coil as a result of the diaphragm moving
it is connected so also vibrates
What type of induction occurs when coil is moving in the magnetic field of magnet
electromagnetic induction
What is the induced voltage like in the microphone and WHY
varying voltage
coil is vibrating to and fro
What machine can be used to increase the voltage of the microphone
an amplifier
