Air Horns

How does a car horn make noise?

Where there ever different forms of the horn? If so, does anyone know how those work(ed)? thanks in advance.

1. a horn and a speaker are the same thing. a horn has a electrical charge send to a diaphragm that vibrates at a frequency and has the air forced past a angled metal flap to enhance the sound. old cars, like model A's had what they called a aUgah horn cause it sounded like it was saying....aUUUgah...aUUUgah. Most car makers horns sound different than each others.
