Electric Automobile Horn

Automobile horn is a device used to alert other vehicles and passersby. When a horn button is pressed, an electromagnet energized intermittently will cause the steel diaphragm to oscillate back and forth producing the sound of the car horn. Automobile horns have become a part of everyday life and one can hardly find an automobile without a horn.
