Template:Sound sample box align right
Template:Sample box end Klaxon is a trademark for an electromechanical horn or alerting device. Mainly used on automobiles, trains and ships, they alert listeners of the vehicle's arrival and possible danger.
The Klaxon's characteristic "AH-OOOOH-GAH!" sound is produced by a spring-steel diaphragm with a rivet in the centre that is repeatedly struck by the teeth of a rotating cog-wheel. The diaphragm is attached to a horn which acts as an acoustic transformer as well as controlling the direction of the sound.
In the first klaxons, the wheel was driven either by hand or by an electric motor. (The electric version has been credited to inventor Miller Reese Hutchison, an associate of Thomas Edison.)
The Lovell-McConnell Manufacturing Co. of Newark, New Jersey bought the rights to the device in 1908. F. W. Lovell, the founder, coined the name klaxon from the Greek verb klazō, "to shriek".
Klaxons were first fitted to automobiles and bicycles in 1908. Electric klaxons were the first electrical devices to be fitted to private automobiles. They were originally powered by 6-volt dry cells, and from 1911 by rechargeable batteries. Later hand-powered versions were used as military evacuation alarms and factory sirens. The klaxon is also famous for its use as a submarine dive alarm.
The English company Klaxon Signals Ltd. has been based in Oldham, England for the last 80 years, with premises also in Birmingham. The French Klaxon company was acquired by the Italian Fiamm Group in the 1990s.
