Horns

Horns



In 1913 Bosch filed the first patent worldwide for automotive horns.

In 1919 we developed the buzzer system, which produces a continous and uniform tone with a singal diapragm. This tone, however, made it difficult for other road users to estimate the direction or proximity of the vehicle. Bosch later introduced a second diaphragm, the 'harmonic diaphragm', which enables other road users to better determine the position of the warning signal.

Later technological advanncements led to more warning device technologies and types, such as compressed-air and electropneumatic fanfare horns.
