A clip-mounted lavalier


A lavalier microphone or lavalier (or lav or lapel mike) is a small electret or dynamic microphone used for television, theatre, and public speaking applications, in order to allow hands-free operation. They are most commonly provided with small clips for attaching to collars, ties, or other clothing. The cord may be hidden by clothes and either run to a radio frequency transmitter in a pocket or clipped to a belt (for mobile work), or directly to the mixer (for stationary applications).

These miniature mics are often supplied with a choice of push-on grilles of differing lengths which provide gentle high-frequency boost by forming a resonant cavity. A peak of around 6 dB at 6-8 kHz is considered beneficial for compensating loss of clarity when chest mounted, and a peak of a few decibels at 10-15 kHz when mounted in the hair above the forehead. This method of boosting high frequencies does not worsen noise performance, as electronic equalization would do.

History

The term lavaliere originally referred to a pendant worn around the neck. Its use as the name of a type of microphone dates from the early 1960s.[1]

The first practical lavalier microphone was invented by Lou Burroughs, co-founder of Electro-Voice, Inc. [2]
