A motor vehicle and water craft horn, comprising: at least one capacitor (C2) of about 220-10000 μF connected in parallel at the input end of the horn power supply to eliminate electromagnetic interference caused by electromagnetic radiation, conduction, and coupling. Also provided is a method of eliminating motor vehicle and water craft horn electromagnetic interference, an electronic device used on a motor vehicle and water craft, and a motor vehicle and water craft. The present invention solves the problem of ultralimit of conducted emission (CE) and radiated emission (RE) when a motor vehicle or water craft uses a horn for CIRS 25 testing, thus enabling the horn EMC index to meet the standard. |
