Problems solved by technology

Because the volume of the horn cannot be controlled according to the driving conditions, it may sometimes scare passers-by, animals, etc., and bring unexpected and serious consequences.
[0004] Fortunately, the above-mentioned problems have been recognized by those skilled in the art, and a car horn that can adjust the volume has been designed. However, most of the similar technologies use electronic components plus template control to achieve volume adjustment, which has complex structures and is difficult to control. , The problem of difficult maintenance makes it difficult to apply a large number of economic models

Abstract

The invention supplies a vehicle speaker that is made up of speaker button, power supply contact, return spring, location metal sleeve, button location thimble, speaker, speaker external board, and power supply lead wire. The speaker external board is installed in flute of steering wheel. Return spring is installed at the down part of speaker external board, and the speaker button is installed onupper part. Variable resistance with insulated section is installed in the cavity of speaker external board. A flute is on the down part of the speaker button. And power supply contact is set on theinside of flute. Loop is formed by variable resistance, speaker, location metal sleeve, and power supply contact. The invention could control the output power of speaker according different situationby driver and decrease safety hidden troubles.

Description

technical field [0001] The invention relates to a car horn. Background technique [0002] Nowadays, in order to beautify the environment and reduce noise pollution, major cities have successively introduced relevant laws and regulations on limiting the sound of cars in the city, which has restricted the use of car horns. However, car horns are an indispensable emergency active safety measure for cars. In many cases, it can remind pedestrians and vehicles in time, so as to avoid traffic accidents. [0003] In order to ensure the warning function of the horn, the current automobile manufacturers generally adopt high-intensity audio output, and only set one intensity, that is, the horn has only one volume. Because the volume of the horn cannot be controlled according to the driving conditions, it may sometimes cause unexpected serious consequences such as frightening passers-by and animals. [0004] Fortunately, the above problems have been recognized by those skilled in the ...
