Abstract

The invention provides a converter enabling sound of a car klaxon to vary from low to high. The converter is characterized in that the converter comprises a 16-24V direct current electrical source, apartial voltage starting circuit, a charge-discharge and gradually louder circuit and a klaxon drive circuit. According to a common typical working mode of a car klaxon, all voltage is applied to theklaxon in an instant during use, the klaxon immediately makes a particularly harsh sound, especially pedestrians on a road are liable to be frightened in the absence of attention, and great harm especially to the pedestrians with heart disease can occur. A working mode is designed that the klaxon sounds gradually from low to high at the moment of switching on a power supply of the car klaxon; andwhen the power supply of the klaxon is turned off, the sound of the klaxon becomes gradually lower, so that the working mode adopted by the klaxon is more humanized.

Description

technical field [0001] The invention belongs to the technical field of electronic automatic control, and relates to a car electric horn sound converter from small to large. Background technique [0002] The typical working mode of common car electric horns is that when the electric horn is in use, the full voltage is applied instantly, and the electric horn immediately emits a particularly harsh sound, especially when pedestrians on the road are not paying attention, they are easily frightened, especially It is extremely harmful to pedestrians with heart disease. Is it possible to design a way that when the power of the car electric horn is turned on, the electric horn gradually makes a sound from small to large, and when the power of the electric horn is turned off, the sound of the electric horn gradually becomes smaller. It is easier for the electric horn to adopt such a working mode Humanize. [0003] The following describes in detail the necessary and key technical co...
