Horns

BeStar offers a range of Vehicle Horns, including electric horns that have found acceptance on a variety of vehicle applications. Various configurations are available. BeStar ISO/TS16949 certification provides the required standard for all kinds of automotive industry needs.

Vehicle horns are usually electric horns, driven by a flat circular steel diaphragm with an electromagnet acting upon it; attached to a contactor that repeatedly interrupts the current to the electromagnet. This arrangement works like a buzzer or electric bell. A spiral exponential horn shape called the "snail" is cast into the body of the horn, to better match the acoustical impedance of the diaphragm with open air, and thus more effectively transfer the sound energy. Sound levels are approximately 107-109 decibels, and current draw 5-6 amperes.

Vehicle Horns may be used singly, or arranged in pairs to produce a chord consisting of two notes, sounded together; although this only increases the sound output by 3 decibels, the use of two differing frequencies is more perceptible than the use of two horns of identical frequency, particularly in an environment with a high ambient noise level. Typical frequencies of a pair of horns of this design are 500 and 405–420 Hz.

An alternative design for electric horns abandons the horn ducting and relies on a larger flat diaphragm to reach the required sound level. Sound Pressure Levels are approximately 109-112 decibels, and current draw 2.5-5 amperes. These electric horns can be either single, or arranged in pairs; typical frequencies for a pair are 420-440 and 340–370 Hz.

Be sure to take a look at our BeStar Automotive Signaling Device Catalog under the Resources Tab to see an expanded listing of vehicle horns and available acoustic products for automotive applications.

BeStar Electronics also manufacturers back up alarms, loudspeakers and buzzers.
