The snail horn is a device that people often need to use when driving a car. Therefore, if the device malfunctions during use, such as poor sound quality, rattling sound, or simply does not sound, it will bring a lot of inconvenience to people's travel and increase the danger of driving on the road. So when the snail horn malfunctions as mentioned above, it is necessary for everyone to analyze and handle in a timely manner what caused the malfunction.

Let's first take a look at how the snail horn works. When the snail 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 snail horn relay. The electromagnetic coil attracts the dynamic contact switch of the relay to close, and the current will flow to the snail horn. The current causes the electromagnet inside the snail horn to work, causing the diaphragm to vibrate and produce sound.
The main faults in the circuit are virtual connections, such as loose terminals of the snail horn plug, burnt contacts of the snail horn relay, and poor contact of the snail horn switch at the steering wheel. But in many snail horn malfunctions, especially in winter, the most common problem is the malfunction of the snail horn itself.
Considering our usage environment and other factors, the main reasons for the malfunction of the snail speaker itself are as follows:
1. Contact erosion: If the snail horn is pressed for a long time, it is easy to cause contact erosion and impedance in the snail horn. The current flowing through the electromagnetic coil weakens, and the electromagnetic suction force decreases, which cannot attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even no sound. But when the snail horn is continuously pressed, if a strong current passes through the impedance in an instant, it can still work normally, so it will sometimes be good or bad.
2. Poor sealing makes it easy to get damp: Although the snail horn is sealed inside, if it is not sealed properly and enters the mist or water vapor in the air during car washing, the water vapor can easily cause the contacts to get damp and not work properly.
3. Poor contact of electromagnetic coil terminals: Some Surabaya snail horn internal electromagnetic coil enameled wire terminal joints are connected by aluminum metal rivet crimping, which is not a reliable welding connection. If the insulation paint on the end enameled wire is not cleaned or the rivet crimping is not secure, it is easy to cause virtual connection faults, leading to poor operation of the snail horn. This type of malfunction is due to the quality of the snail horn and cannot be repaired. It can only be replaced with a new part.
