A FM transmitter is an electronic device that is widely used in car radio for drivers to enjoy radio broadcastings. By receiving different FM signal, the car stereo can broadcast the music or other sound. FM transmitter is a portable car kit that can cheer you up on the road.

 

You may be confused why the car stereo can broadcast all types of radio programs on the road only with the small FM transmitter. Actually, the FM transmitter is a bridge between audio output and FM signal. When receiving a specific audio output, an FM transmitter will convert it into FM signal that the car radio can detect and receive immediately. Then the radio can broadcast music and other sounds.
