Why did the car horn suddenly stop working?

[Scarlett]

The horn is the sound signal device of a car. During driving, the driver issues necessary sound signals as needed and required to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and conveying signals. Here is additional information: 1. The principle of a car horn: An electric car horn produces sound through the vibration of a metal diaphragm. It consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. The working principle of an air horn is to use the airflow of compressed air to vibrate the metal diaphragm and produce sound, so it can only be used on vehicles equipped with an air compressor. 2. Reasons why the horn does not work: Check the sound of the horn. If it sounds unclear, low, or weak, it is mostly due to poor contact at the connection points. Repeatedly pressing the horn switch, if the horn sometimes works and sometimes does not, is mostly due to poor contact inside the switch. If there is a significant "hissing" friction sound when turning the steering wheel left or right, some lubricant can be sprayed onto the relevant contact points.
