Electronic horn


Electronic horns are used on vehicles to give out warning signals generated by an electronic circuit. A solenoid is magnetized and demagnetized to produce the fundamental frequency and cause the diaphragm to vibrate. This generates high pressure that passes through the trumpet horn to generate a sound. A key advantage of electronic horns is their lack of wear, resulting in average lifetimes ten times higher than with electromechanical horns.
