What is the function of car tweeters?

The function of car tweeters: to reproduce the high-frequency signals (generally in the range of 5KHz-10KHz) output from the crossover. Tweeters are mainly dome-type. Dome tweeters can be divided into positive dome units and inverted dome units based on their dome structure. Here is some additional information: 1. Main function: Since the primary role of tweeters is to express the delicacy of sound, their installation position is very particular. If the installation position is not scientific during car audio modification, it will result in unsatisfactory sound field effects. 2. Installation at ear level: Tweeters should be installed as much as possible at a position level with the human ear, such as on the car's A-pillar, on top of the dashboard, or on the door in some car models. This way, the sound field is basically level with the ear, and the driver can better experience the charm of the music.
My car just got new horns installed. The high-pitched horn is mainly for emitting sharp sounds to alert others. In the city, when an e-bike suddenly cuts in or the car ahead isn't paying attention, pressing this horn can penetrate through, carrying farther than regular horns. On highways, pressing it twice helps truck drivers spot me in their rearview mirrors when overtaking. This thing pairs with the bass horn—the high pitch handles penetration while the bass provides volume and depth, together sounding like the brass section in a symphony. Some cars nowadays even allow tone adjustments; my neighbor's car honks like an ambulance siren, making it super noticeable. But you gotta be careful not to honk recklessly—last time I tested the horns in the neighborhood, the security guard scolded me.
You must have encountered situations where honking doesn't get any response while driving, right? That's exactly what high-pitched horns are designed to solve. Ordinary horns produce dull sounds that can easily be drowned out in noisy environments. High-pitched horns, with their higher frequency and stronger penetration, can create echoes throughout a tunnel with just one honk. They are typically installed near the front grille, where metal diaphragms vibrate to produce sound waves around 3000 Hz, a frequency to which human ears are most sensitive. I remember driving long distances in foggy weather before, and it was the repeated use of the high-pitched horn that helped remind the car ahead to maintain distance.
The essence of car horns boils down to two words: warning. Its working principle involves an electromagnet driving a metal diaphragm to produce high-frequency sound waves. These high-frequency sounds have strong penetration and are particularly effective in rainy and windy conditions. In the city, when encountering pedestrians crossing the street while distracted by their phones, a quick honk can immediately grab their attention. Using it in combination with turn signals during highway overtaking enhances safety. However, excessive use can lead to noise pollution, and some regions in Europe have restrictions on horn usage times.
