How to distinguish the high and low sounds of a car horn
In car driving, the horn is an important safety device used to alert other vehicles or pedestrians. The speaker's tone is divided into treble and bass, and the combination of the two can produce clearer and more penetrating sound. This article will introduce in detail the classification, principles and purchase suggestions of car horns’ treble and bass.
1. Classification of high and low pitches for car horns
Car speakers usually consist of a tweeter unit and a woofer unit, which achieve layered sound through different frequency ranges. Here are the main differences between tweeters and woofers:
| Classification | frequency range | Sound characteristics | Applicable scenarios |
|---|---|---|---|
| tweeter | 2000Hz or above | Sharp and penetrating | Urban roads, congested sections |
| woofer | Below 500Hz | low, thick | Highway, long distance reminder |
2. Working principle of treble and woofer speakers
The tweeter generates high-frequency sound waves through electromagnetic vibration, which is suitable for rapid transmission over short distances; the woofer generates low-frequency sound waves through a larger diaphragm, which is suitable for long-distance transmission. The combination of the two can cover a wider frequency range and improve the warning effect.
3. How to choose tweeter and woofer speakers
When purchasing a car horn, you need to consider the following factors:
| factor | tweeter | woofer |
|---|---|---|
| Installation location | Near the front of the car or dashboard | In the bumper or engine compartment |
| Power requirements | Lower (below 30W) | Higher (above 50W) |
| Applicable environment | city road | highway or country |
