How does a microphone works? how can it converts audio into digital?
In: Technology
Microphones don’t convert audio to digital.
Microphones just convert audio into analogue signals.
Converting those analogue signals to digital signals is the job is the job of a DAC a digital audio converter.
The same basically goes for traditional headphones and speakers which also just convert dumb analogue electrical signals into analogue audio signals.
Speakers and microphones are basically the same sort of machine working in opposite directions.
Sound is air (or other stuff) moving back and forth in waves. The moving air can be turned into electrical pulses with a magnet and induction. reversing that process can make electric pulses move magnet which in turn moves the air around it which is sound.
All that is simple analogue technology that works more or less the same it did back in the days of Alexander Graham Bell and the first telephone.
Converting the analogue electrical signal into a digital signal is more involved and more modern and takes a specialized electronics to do.
