A portable microphone unit for use in wireless transmission communication
system is disclosed where the microphone unit includes a housing for
containing at least one, but usually two or more, microphones for
receiving a speaker's voice, coupled with IR, RF, or other types of signal
emitters, wherein the microphone housing is attached at a free end of
wearing element, made from a flexible or inflexible material. The wearing
element is either shaped to sit on the speaker's body, such as around his
neck, and place the microphone before the speaker's face and mouth or is
made from a flexible material that may be bent into a desirable position.
The microphones are situated with appropriate angles in between, thereby
allowing the speaker to turn his head from side to side and still maintain
a significant sound pressure level towards at least one microphone and
achieve a strong signal.
