How does car radio work?

icon/user/avatar/20 Created with Sketch. By Viktor Kalutsky

Radio:The transmission and reception of electromagnetic waves of radio frequency, especially those carrying sound messages.”


“The Best Cars in Town !” BCR Automotive Inc | Auto Dealership in Portland,


There are millions of cars on the road today and most of them come with the feature called mp3 player which gives you options either to play your music, podcasts or just the radio. This feature is used by millions of people every day making it the most used car equipment on the market and just like a regular radio its design is simple. 


  1. The antenna received radio waves from the radio stations.

  2. The antenna is connected to the tuner which displays which radio station you’re on and something we use to adjust the station.

  3. After the tuner comes detector which is “a detector is a device or circuit that extracts information from a modulated radiofrequency current or voltage. The transmitter was switched on and off to produce long or short periods of radio waves, spelling out text messages in Morse code.” 

  4. The next comes an amplifier which is an “electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction.”

  5. The last step to how radio works is a speaker which puts audio out electrical signals into audio using a metal coil which creates a magnetic field.
