Patent No. 97219874.1 The motor vehicle non-contact electric horn stabilizes the sound pressure level by adjusting the input signal strength of the power amplifier, so that the power amplifier will be in the amplified state, and the power amplifier tube will generate heat, which is easy to burn and has poor practicability
[0004] Electric horn is a necessary safety signal device on motor vehicles. With the rapid increase of the number of motor vehicles, the sound of electric horns has become one of the main sources of traffic noise. In order to reduce this noise, major and medium cities across the country , especially the bustling roads have implemented banning, although this can reduce noise, but it has brought a lot of inconvenience to drivers and pedestrians, and traffic accidents occur from time to time
At present, special devi

Abstract

The invention relates to a key-press input module which comprises a motor vehicle horn key-press, a stabilivolt tube DW2, a resistance R3 and a resistance R4, wherein one end of the motor vehicle horn key-press is connected with the power output positive end or the power output negative end of a motor vehicle battery jar, the other end of the motor vehicle horn key-press is connected with a digital signal input end IN1 of a single chip microcomputer through the resistance R3, the digital signal input end IN1 of the single chip microcomputer is also connected with a digital signal output end O1 through the resistance R4 and also the cathode of the stabilivolt tube DW2, the anode of the stabilivolt tube DW2 is in grounding, and one end of the motor vehicle horn key-press is connected with the power output positive end or the power output negative end of the motor vehicle battery jar through a single-pole double-throw switch. The invention provides the key-press input module which has the advantages of simple structure and convenient use.

Description

technical field [0001] The invention relates to a key input module. Background technique [0002] At present, the driving frequency of electric horns of motor vehicles is fixed before leaving the factory, and the natural frequency of electric horns will change due to changes in environmental conditions during use (for example: changes in temperature between winter and summer, air pressure between plains and plateaus) Changes, etc.) and changes in the mechanical properties of the electric horn can cause its change. Since the resonant peak of the electric horn diaphragm is very sharp, if the driving frequency cannot be adjusted in time, it may cause a sharp drop in the sound pressure level of the electric horn , or even be scrapped, which will affect the prompting effect and increase the energy consumption. For example: Patent No. 98807769.8 The method and device for frequency stabilization of electric horns, the driving frequency is solidified in the program before leaving t...
