A microphone is an energy converter that converts a sound signal into an electrical signal. There are moving coil, capacitive, electret and recently emerging silicon micro microphone. In addition, there are liquid microphone and laser microphone. Most microphones are electret capacitor microphones, which work by using a polymer diaphragm with permanent charge isolation.

Microphone tattoo means every opportunity in life. No matter whether the microphone is in your hand or robbed, don’t lose your fighting spirit. As long as you work hard and struggle tirelessly, one day, you will hold your microphone. Life is an art. As long as you insist on working hard to improve yourself, improve yourself and make a little progress every day, I think one day you can seize the opportunity and achieve your own success.
