The owner honks the horn for a long time, which is easy to cause contact ablation and lead to silence.

Horn is an important equipment in automobile. Some car owners have the habit of honking their horns for a long time. Is this habit harmful to speakers?

Chen Guohong, technical director of after-sales service department of Dongfeng Nissan ZOJE Nissan franchise store, said in an interview that pressing the horn for a long time will easily lead to the ablation of horn contact and impedance, and the current flowing through the electromagnetic coil will be weakened, so the electromagnetic attraction cannot attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even silent pronunciation.

"If the car horn doesn't ring or makes abnormal noise, it is necessary to distinguish whether it is a line fault or a fault of the horn itself." Chen Guohong told reporters that if the headlight brightness is normal, press the horn button to check whether the relay has a "click, click" sound. If there is noise, it may be that the horn is damaged, and the horn assembly should be replaced; If there is no noise, the horn relay or horn button may be damaged. Horn relay is damaged and should be replaced; If the horn button is damaged, you can remove the horn button on the steering wheel and short it with wires in case of emergency.

Chen Guohong said, it is particularly important to note that if the vehicle is equipped with airbags, never try to disassemble the steering wheel, so as to avoid the airbag opening and personal injury due to misoperation, and it should be repaired by professionals.

Chen Guohong told reporters, "The terminals of electromagnetic coils in some loudspeakers are connected by aluminum rivets, so the welding is unreliable. If the insulating paint on the end enameled wire is not cleaned or the rivet is not firmly pressed, it is easy to have a virtual connection failure. "

In view of the daily failures, Chen Guohong suggested that car owners should pay attention to the following matters when using car horns: remember to prevent the horn from getting wet when washing the car, and blow dry it with an air gun as soon as possible when finding that the horn is flooded; Don't always honk the horn for a long time; Try to seek the help of professional maintenance technicians when the horn fails, and don't blindly replace the horn, which is easy to cause unnecessary waste. @20 19
