During the use of snail horns, various malfunctions such as single tone, poor sound quality, and no sound may inevitably occur due to certain factors. If not addressed in a timely manner, they can cause considerable inconvenience to normal driving. Today, I will analyze the common malfunctions and causes of snail horns for everyone, hoping to provide some help.
Firstly, let's briefly understand the working principle of the 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.
Common faults and solutions of snail horn:
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
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.
Due to the fact that the snail horn is a mechanical device, it is inevitable that malfunctions may occur during use due to the temperature of the car or dust during driving. The editor suggests that once this situation is discovered, it is best to seek professional repair companies to prevent it from affecting use.
The snail horn is an important device in the use of cars, so once a malfunction is found in the electronic snail horn processing customized horn, it must be promptly and accurately resolved to prevent affecting the safety of car driving.
