A Car FM transmitter is a portable device that converts the audio output into an FM radio signal, which can then be picked up by appliances such as car or portable radios. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. The power source is usually supplied by the cigarette light socket. They are typically used with portable audio devices such as CD or MP3 players. Most devices typically have a range of up to 30 feet (9 meters) with any average radio.
