From Wikipedia, the free encyclopedia
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.
