What does the diaphragm in the speaker do?
- The diaphragm moves to match the analog signal, which creates changes in pressure in the air to create sound.
- The air molecules are spaced apart.
This is rarefaction.
- The diaphragm moves to match the changes in air pressure, which is recorded and sampled in the digital converter.
This is the diaphragm in the microphone.
- The air molecules are dense.
This is compression.
