Automobile Horns

Are usually electric klaxons, driven by a flat circular steel diaphragm that has an electromagnet acting upon it and is attached to a contractor that repeatedly interrupts the current to the electromagnet.

This arrangement works like a buzzer or electric bell. There is usually a screw to adjust the distance/tension of the electrical contacts for best operation.

A spiral exponential horn shape (sometimes called the "snail") is cast into the body of the horn to project the sound effectively.
Sound levels are approximately 107-109 decibels, and current draw 5-6 amperes.
