What to Do When Car Horn Bass Produces Buzzing Resonance?

First, reset all additional functions of the car audio system to factory settings, and center the high, mid, and low tones as well as the left-right balance. Below is an introduction to air horns: 1. Concept: An air horn is a type of car horn, categorized into electric air horns and mechanical air horns. Air horns use compressed air flow to vibrate a metal diaphragm, typically shaped like a long horn (cylindrical), producing loud, high-pitched sounds that travel far. 2. Maintenance: Clean surface dirt during maintenance; replace the diaphragm if rust or damage is found upon disassembly. When washing the vehicle, avoid directing water into the horn casing to prevent affecting its sound. The QL11 type air horn requires an air pressure of 294~980 kPa for normal sound performance.
I often encounter the issue of low-frequency buzzing and resonance from the car horn while driving, which makes me feel very uncomfortable, especially when honking at narrow intersections where it produces harsh echoes. I remember last time my car had the same problem, and after inspection, it was found that the horn mounting screws were loose. Tightening them with a wrench resolved the resonance. If the buzzing persists after securing the screws, it might be due to an aging or damaged horn unit, and replacing it with a new universal horn costing just a few dozen dollars should do the trick. Additionally, check if the wiring connections are secure, as broken wires or poor contact can cause abnormal noises. If there’s a resonance point in the car body, adding a rubber vibration-damping pad to isolate the horn position can also help prevent the issue. Don’t overlook the safety risks—buzzing can affect auditory judgment, so timely action is better than delaying. Also, avoid exposing the horn to water or dust when parking to extend its lifespan.
