Why does the car horn sound muffled after wading through water?

[VanRosalie]

Since the horns of most vehicles are installed near the front bumper, when the vehicle wades through water, external water enters the high or low-frequency horn, causing a change in sound. Here are the relevant explanations: 1. Handling after the horn gets water: When a change in the horn sound is noticed, the horn should be removed immediately. You can remove it yourself or take it to a professional repair facility. After removing the horn, dry the accumulated water inside. Once handled, the horn should return to normal and can continue to be used. If the horn still sounds muffled after handling, the damaged horn must be replaced. 2. How the car horn works: The car horn mainly consists of an iron core, magnetic coil, contacts, diaphragm, etc. When the driver presses the horn switch, current passes through the contacts, generating magnetic force through the coil, causing the diaphragm to move, which connects the resonator with the diaphragm to produce sound.
