Can You Honk the Horn in Urban Areas?

[LeEmily]

Local policies vary, and honking is prohibited in some urban areas. Honking regulations: Honking in areas or sections where it is prohibited may result in fines as stipulated by law. Relevant laws and regulations clearly state that vehicles such as fire trucks, ambulances, and engineering rescue vehicles can use horns and sirens with compliant audio when performing emergency tasks. How car horns work: An electric car horn produces sound through the vibration of a metal diaphragm. The electric car horn consists of an iron core, a magnetic coil, contacts, an armature, a diaphragm, etc. Current flows through the contacts to the coil, which generates 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 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, closing the contacts and reconnecting the circuit. Current flows through the contacts to the coil again, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound.
