What Is A Tube (Vacuum Tube) Microphone?

- Jul 30, 2018-

A tube microphone is essentially a type of condenser microphone that uses an electron tube to transmit the acoustic signal picked up by the diaphragm. The diaphragm and the tube circuit work together, and the diaphragm is pressed by the sound to cause a change in the capacitance, thereby inducing a current signal, which is transmitted through the tube as a core circuit. The tube acts as a preamplifier here, and through the tube technology, a warm and smooth sound can be obtained.
