Sound Recording and Reproduction
... one of these plates is made of very light material and acts as the diaphragm. The diaphragm vibrates when struck by sound waves, changing the distance between the two plates and therefore changing the capacitance. Changes in the capaciatnce produces a corresponding audio electric signal. A voltage i ...
