A motor vehicle and/or water craft horn, comprising: at least one capacitor (C2) of about 220-10000 µF connected in parallel at the input terminals of the horn power supply to eliminate electromagnetic interference caused by electromagnetic radiation, conduction, and coupling. Also provided are a method of eliminating motor vehicle and/or water craft horn electromagnetic interference, an electronic device for using on a motor vehicle and/or water craft, and a motor vehicle and/or water craft. The present invention solves the problem of overrun out of limit 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.

An apparatus related to a contactless sound device, such as a horn, which may be configured to output different and/or multiple pitches using a replaceable, or interchangeable, electronic integrated circuit (“IC”) module is disclosed. The electronic IC module may include one or more sequencers electrically connected via one or more relays to at least one signal generator which is electrically connected to an output driver. Each signal generator is configured to generate at least one frequency signal, and optionally multiple frequency signals. The electronic IC module may be physically attached to an IC connection interface located on the exterior of the contactless horn body. The IC connection interface electrically connects the electronic IC module to an electro-magnet that drives the diaphragm of the contactless horn to create the selected preconfigured frequency sound.

There is provided a method for generating turn-signal sound of a vehicle and a device using the method which can output from a speaker the turn-signal sound close to operating sound of a mechanical relay. The method outputs a pulse signal for turn-signal sound having varying frequency and duty ratio from a PPG port of a CPU, integrates the pulse signal for turn-signal sound using an integration circuit to convert into an analog signal for turn-signal sound which is outputted to a speaker. The method also outputs a pulse signal for alarm having the constant frequency and duty ratio, integrates the pulse signal for alarm sound using an integration circuit to convert into an analog signal for alarm sound. Then the analog signals for turn-signal sound and for alarm sound are summed up and outputted to the speaker to produce simultaneously the turn-signal sound and the alarm sound.
