Why is a Horn Called “Snail Horn”

2023-07-07

The snail horn is a horn that is equipped with a snail-like auxiliary cavity on an ordinary horn, which can improve the sound quality and increase the volume. Because it looks like a snail, it is called the snail horn to distinguish it from the disc horn. Actually, it is called "compound horn", with a high voice horn and a low voice horn.


Working principle:

The signal is generated by pulse pressure. Sound transmission is a relatively harmonious spread of the fan divergent transmission. The sound waves of the snail horn are deflected to the sides from the exit of the horn. Therefore, the sound of the snail horn is transmitted in a fan way and the sound is harmonious.


Advantages:

The snail horn is used to warn fast approaching drivers, and its warning signal allows the driver to estimate the distance and direction of the warning vehicle.

The snail horn is made of high-quality materials, so it is all-weather, salt-resistant. The snail horn is resistant to the impact of coarse sand and stone fragments, and can adapt to all kinds of weather.


Sound:

Snail horn because of its structure through the vibration of the sound box, with the same power, its sound will become larger, spread farther and relatively power-efficient. The sound sounds robust, loud and full.

The sound of general electric horn is like “O, O——”; the sound of the snail horn is like “BA, BA——”.

Compared with the traditional horn, the snail horn has a fuller sound and a longer life.
