Electronic snail horn is a very common type of horn, which is installed on many vehicles nowadays. Its sound is relatively low, so it is still very popular. However, sometimes the product may also experience some common malfunctions. How should we deal with this phenomenon? Next, the editor will take a look together, hoping to be helpful to you.

The electronic snail horn is a device frequently used while driving. If the horn malfunctions, it can be very inconvenient while driving. Sometimes when I honk my horn, the sound is either mosquito like, hoarse, or even completely silent. To understand the cause of this phenomenon, we should first understand how electronic snail speakers work. When the horn button on the steering wheel or other positions 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
Considering factors such as usage environment, the main causes of speaker malfunctions are as follows:
(1) Contact erosion: If the horn is pressed for a long time, it is easy to cause the horn contact to burn and produce impedance. 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 horn is constantly honked, if a strong current passes through the impedance in an instant, it can still work normally, so it can be good or bad at times;
(2) Poor sealing can easily cause moisture damage: Although the interior of the horn is sealed, if it is not sealed properly, it can easily cause moisture damage to the contacts and prevent them from working properly due to the presence of fog or water vapor in the air during car washing;
(3) Poor contact of electromagnetic coil terminals: Some 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, resulting in poor horn operation. This type of malfunction is due to the quality of the speaker and cannot be repaired. Only new parts can be replaced.
Common faults and solutions of electronic snail speakers:
1. Line malfunction
The main faults in the circuit are virtual connections, such as loose terminals of the horn plug, burnt contacts of the horn relay, and poor contact of the horn switch at the steering wheel. But in many horn malfunctions, especially in winter, the most common problem is the malfunction of the horn itself.
2. Malfunction of the horn itself
