How Many Horns Does a Car Generally Have?

[GiselleDella]

Generally, a car has a pair of horns, which means two. Below is relevant information about car horns: Function: The horn is the sound signal device of a car. During driving, the driver emits necessary sound signals as required and regulated to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. It is also used for urging and transmitting signals. Working Principle: The car electric horn produces sound through the vibration of a metal diaphragm. When the horn switch is pressed, current flows through the contacts to the coil, generating magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature disconnects the contacts, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the spring plate, closing the contacts again and reconnecting the circuit. Current flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle continues, causing the diaphragm to vibrate repeatedly and produce sound.
