Abstract

Magnetic iron and Hall integrated component is adopted to replace slip ring - carbon brush type horn button. Based on depth degree of horn button pushed by driver, sound from high or low tone loudspeakers is controlled. Thus, the invention solves issues of descending volume of horn and reliability. The system includes horn button, fixing seat for Hall component, relay, high and low tone loudspeakers. Fixing seat for Hall component is fixed on the post of steering wheel. Being sheathed on the fixing seat for Hall component, the horn button can be moved inside hole of the fixing seat along the post of steering wheel. Return spring is installed between horn button and the fixing seat. Two rows of annular magnet and Hall components corresponding to high or low tones are installed respectively. Hall components for high or low tone are connected to relays of loudspeakers respectively. Hall components through connecting line are connected to power source.

Description

technical field [0001] The utility model relates to the technical field of automobile electronics and is generally applicable to various types of vehicles. technical background [0002] At present, most automobiles adopt dual-tone horn and slip ring carbon brush structure. Two tweeters and woofers are connected in parallel with each other, and the speakers are connected in series. At the same time, the horn button adopts a contact type. When the driver presses the button, the two horns sound at the same time, and the volume is fixed. Contents of the invention [0003] Magnet and Hall integrated components are used to replace the traditional slip ring carbon brush structure horn button, which solves the problem of reduced reliability caused by the fixed volume and contact type of the car horn. The system controls the sound of the high and low speakers respectively according to the depth of the driver's pressing of the horn button, meeting the driver's requirements for th...
