This diaphragm is depressed by sound waves causing a change in the distance between the diaphragm and electrode, causing a voltage change that is subsequently rendered as recorded, amplified, or broadcast sound. These microphones require a separate source of electrical current to operate, unlike dynamic or ribbon microphones. ]]></note></mads>
