Nowadays, many people install electronic snail speakers in their cars because their sound is relatively deep and rich, not harsh. When we go out to drive, we use the horn very frequently. Its presence can remind people to avoid it in time. If it malfunctions, it is very inconvenient. The malfunctioning electronic snail horn has some loud and some low sounds, and the silver color becomes unpleasant and harsh. Let's take a look at the reasons for this phenomenon.

Before looking for the cause, let's first take a look at how the car's horn works. After pressing the horn button on the steering wheel, the current from the car's battery will flow through the circuit to the horn relay, and eventually the current will reach the electromagnetic coil inside the horn, causing it to vibrate and make a sound. Generally, the fault of the horn is the horn itself. Some horns have installation defects, and when it rains, they are easily wetted by rainwater, which directly leads to the damage of the horn.
Generally, there are three common parts that cause malfunctions when a horn does not sound. Car owners can check it themselves:
① When driving normally, there may be a phenomenon where the horn sometimes rings and sometimes does not, which is mostly caused by poor contact at the horn switch.
② The sound of the horn is not bright and appears hoarse, which is due to poor contact of the horn plug, especially around the steering wheel. Frequent use can cause wear on the contacts, resulting in hoarse horn sound.
③ If the horn doesn't sound at all, first check if the fuse is blown, then unplug the horn plug for measurement, use a multimeter to measure if the horn switch is still powered on. If there is no power, it means there is a broken part in the horn harness. If there is power, it means it is a problem with the horn itself. If the nut on the horn cannot produce sound after adjusting, it means it should be replaced with a new horn.
Maintenance of Electronic Snail Speaker:
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.
