Is the Car Horn a Wear-Prone Part?

[RubyRose]

Car horns are considered wear-prone parts, with their service life depending on the quality of the horn and the frequency of use. Function of the horn: During vehicle operation, drivers use the horn to emit necessary sound signals as required by regulations, warning pedestrians and alerting other vehicles to ensure traffic safety. It is also used for urging movement and conveying signals. Working principle of the horn: When the horn button is pressed, current flows through the contacts and into the coil, generating a magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current. The magnetic force of the coil then disappears, allowing the diaphragm and armature to return to their original positions under the action of their own elasticity and the spring plate, closing the contacts and reconnecting the circuit. Current flows through the contacts and coil again, generating magnetic force and repeating the above process. This cycle causes the diaphragm to vibrate continuously, thereby producing sound.
