car horn

Abstract

The invention discloses an automobile electric horn, which includes a main body and a sounding part. The main body is provided with a sound channel, and the sound channel is provided with a spiral channel for propagating and amplifying the generated sound. The side of the main body is The wall is provided with an auxiliary sound channel for diffusing sound, and the auxiliary sound channel communicates with the slot between the helical passages, the sound-generating part includes a circuit board, and the sound-generating part changes the magnitude of the current through the circuit board to emit sounds of different amplitudes , to break the original sound outlet with a fixed direction and a fixed number, design an auxiliary sound channel on the side wall, and combine the sound from the sound part to gradually amplify the sound through the spiral channel, and expand the divergence angle of the sound so that the effect of surround sound can be produced. While increasing the volume of the horn, it avoids the ear-piercing feeling when the volume is too loud, because the increase in the volume is to prevent accidents from hearing the horn for the elderly or people with poor hearing who cross the road, and increase the use of the horn safety.

Description

technical field [0001] The present invention relates to a horn, more specifically, it relates to a car electric horn. Background technique [0002] The horn is an indispensable electrical component in the car safety system. The sound of the horn is used as a vehicle-specific language for traffic information between vehicles and between vehicles and people. Although many cities are not allowed to honk horns in urban areas due to noise problems, most other roads are inseparable from horns, so its role in prompting and warning is irreplaceable. Generally, cars are equipped with a total of 2 speakers, high and low, which produce a pleasant reverberation sound when they occur together. [0003] Because the car is affected by the bumps, engine vibration, temperature and humidity, the horn should have the ability to work reliably under special harsh environmental conditions. The space is getting smaller and smaller, so long life, vibration and shock resistance, sealing, miniatur...

Problems solved by technology

[0007] In many traffic accidents, there are many accidents due to the fact that the elderly cannot hear the sound of horns from afar and the inconvenience of their legs and feet when they cross the road. Especially during the peak hours, the problem of the elderly crossing the road will be magnified. Highways are more likely to cause traffic paralysis, and traffic accidents may occur in severe cases, endangering people's lives. However, at present, car horns only make a monotonous and harsh sound. No matter how you honk the horn, the sound cannot be amplified. If you install a speaker with a louder volume, although it can be heard by people with poor hearing, it will cause noise pollution and seriously affect the normal life around you.
