Live microphone software

In the microphone, the vibration of the sound is transmitted to the diaphragm of the microphone, which pushes the magnet inside to form a changing current, so that the changed current is sent to the subsequent sound processing circuit for amplification. It would be better if used with microphone software.

It is connected to a needle by a metal septum, and this needle scratches a pattern on a piece of metal foil. When you speak towards the diaphragm, the resulting air pressure difference causes the diaphragm to move, thereby moving the needle, and the movement of the needle is recorded on the metal foil.

Later, when you move the needle back on the metal foil, the vibration caused by scratching on the metal foil will move the diaphragm and reproduce the sound.If it used with microphone software, the effect will be more obvious.
