Everyone knows that when a microphone is used, you will be able to make your voice sound louder. But how does it exactly work?
A microphone converts sound energy into electrical energy, which travels to the speakers and eventually converts this electrical energy into sound energy. The most important component of a microphone is a diaphragm. This is the part that captures the sound waves to create the signal. The diaphragm vibrates when it detects sound waves. This part is attached to a coil and when it vibrates, the coil moves backward and forward around a magnet. As a result, current is generated.
Types Of Microphones Used On Stage Or Presentations
There are two types of microphones commonly used on stages and during presentations: dynamic and crystal. Dynamic microphones work with the help of electromagnetic induction. This type contains a magnet that induces current to flow in the wire. Once the diaphragm vibrates due to sound waves, the magnet gets moved and this movement creates a small current. They are strong and moisture-resistant and as such, are mainly used in the stage performances or speaking engagements.
Crystal microphones are often used as to amplify sound from acoustic musical instruments. This type of microphone contains a crystal which is attached to the diaphragm that creates the signal when the diaphragm gets vibrated by the sound waves. It works according to piezoelectricity – a scientific principle wherein crystals that produce a voltage when subjected to pressure can convert vibrations into electrical signals.
