Snail horn is a type of horn commonly used in many vehicles nowadays, because its silver color is relatively good and popular among the public. However, when using snail horn, one thing to pay attention to is to regularly maintain it, especially if it frequently comes into contact with water, which may cause some malfunctions. Below, the editor will focus on it for everyone.

The snail horn is actually a snail shaped auxiliary sound chamber installed on a regular speaker, which is generally used to improve sound quality and enhance volume. The reason why it is called the snail horn is to distinguish it from the bowl horn. In fact, its full name is called the "high and low frequency horn" because its two speakers are one for high and one for low frequency.
The working principle of snail horn:
When the horn button on the steering wheel or elsewhere is pressed, the current from the battery will flow through the circuit to the electromagnetic coil of the horn relay. The electromagnetic coil will attract the dynamic contact switch of the relay to close, and the current will flow to the horn. The current causes the electromagnet inside the horn to work, causing the diaphragm to vibrate and produce sound.
Maintenance of Snail Horn:
(1) Regularly keep the appearance of the horn clean and ensure that all wiring is secure.
(2) Regularly check and tighten the fixing screws of the horn and bracket to ensure reliable grounding.
(3) The method of fixing the horn has a significant impact on its pronunciation. In order to ensure the normal sound of the horn, it cannot be rigidly installed, so it is fixed on a buffer bracket, that is, a sheet-like spring or rubber pad should be installed between the horn and the fixed bracket.
(4) Regularly check the output voltage of the generator. High voltage can burn out the horn contacts, while low voltage (below the rated voltage of the horn) will cause the horn to produce abnormal sounds.
(5) When washing the car, do not rinse the horn directly with water to prevent water from entering the horn and causing it to not sound.
(6) When repairing the horn, attention should be paid to the position of each metal pad and insulation pad, and they should not be installed incorrectly.
(7) The continuous pronunciation of the horn should not exceed 10 seconds to avoid damaging the horn.
(8) Do not put any foreign objects into the speaker to avoid causing abnormal sounds.
