How does a wireless lavalier microphone work?
A lavalier or lapel mike is a convenient, subtle way to be heard when addressing an audience. The wireless clip on microphone means that you do not need to hold a microphone, so people who are acting or speaking on stage move naturally without carrying something in their hands.

Overview of wireless microphones
Teachers and vicars can also use a wireless lapel microphone system to be heard while carrying on normal work.
Description of these microphones
If you want to use a wireless lavalier microphone, it helps to understand how they work. You need to have the audio microphone that clips to your clothing, the transmitter, and the receiver so that people can hear you.
Omnidirectional mic
An omnidirectional mic allows people to hear you speaking in all parts of a room, although the sound is often not crisp enough to hear lyrics when speaking.
Features of the microphones
When you speak into a microphone, the sound waves cause an electrical current to move. This is transmitted through a speaker as an amplified sound. Lapel mics and lavalier mics are similar, but instead of your purposefully speaking into the microphone, the wireless lapel mic picks up on your voice and broadcasts it across the channel it is assigned.
Wearing a lavalier or lapel mic
Description of the lavalier
A lavaliere is a necklace, and some lapel mics can be worn as necklaces. However, this will lead to uneven sounds. Most of this style microphone is clipped to the shirt so that it will have a steady stream of sound from the same range. The transmitter can be worn on a necklace.
Professional singing
For professional singing, the mic needs to be closer and more consistent than a shirt clip. The lavaliere mic will be put around the face area, usually in the singer's hair or by the person's ear. These are well hidden, and most professional lapel mics are so small that they can be strategically placed so that they can not be seen.
If you are a consumer getting a microphone for use in a classroom, church, or office for a presentation, it does not matter if the mic can be seen. Instead, you want to buy a microphone that will pick up sound clearly and transmit it bidirectionally or omnidirectionally so that everyone can hear you.
Remember to remove the mic when you are having private conversations: even a whisper is transmitted with a lapel mic.
