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. Our products are fitted to leading car brands, the best in the industry.

Volume : This is one of the main key performance indicators for a horn’s characteristics. HELLA has a wide product range of horns in the volume range of 108 dB(A) to 118dB(A)
Functional Principle : Horns are powered by the battery current signal, which is commonly handled by a voltage pulse sent from the steering wheel. The current signal is transferred to a relay, which transmits the entire control current, preventing voltage drops. As the horn is powered by the electric current, it forms a magnetic field, which attracts a metal core together with a steel diaphragm. This attraction causes vibrations, which are transformed by varying resonances in order to gain low or high tones.
Nominal Voltage : (1) 7 – 12 V: for automotive vehicles, agricultural machinery, construction machinery, etc. (2) 7 – 24 V: for commercial vehicles, buses, municipal vehicles, etc.
