Where is the horn located in a Volkswagen car?

[DeCamilla]

Volkswagen car horn is located on the steering wheel, marked with a horn symbol. Its function is to emit sound signals as needed and required, alerting vehicles and pedestrians to the approaching car, thereby enhancing driving safety. The horn consists of an iron core, magnetic coil, contacts, armature, and metal diaphragm. The working principle of the horn is that when the horn switch is pressed, current flows through the contacts to the coil, which generates magnetic force to pull down the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to disconnect, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, under its own elasticity and the action of the spring plate, returns to its original position along with the armature. The contacts close the circuit again, allowing current to flow through the contacts to the coil, generating magnetic force. This cycle repeats, causing the diaphragm to continuously vibrate and produce sound. The resonance plate is rigidly connected to the diaphragm, making the vibration smooth and the sound pleasant.
