- A lavalier microphone, also commonly known as a lapel microphone, is a tiny wireless microphone used often in movies, TV production, theater and public speaking settings. Lavalier mics allow the speaker's hands to remain free and allows a wide range of movement while speaking or performing without being tethered to a fixed microphone. Think of Oprah taping her daily talk show--she walks around and can be heard with only a small mic visible on her neck or chest area.
- Lavalier or lapel microphones transmit sound over localized radio waves via a battery-powered radio frequency transmitter that is hidden away in a pocket, waistband or somehow strapped to the speaker.
- The transmitter secreted on the speaker then communicates over the radio frequency with its base that mixes, controls and amplifies the sound picked up via the microphone.
