How to distinguish high and low pitches from car horns
In car audio systems, the distinction between high and low speakers is a common technical problem. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of how car speakers distinguish high and low sounds, and provide structured data for easy understanding.
1. Basic concepts of high and low pitch of car horns
The high and low pitch of a car horn usually refers to the frequency response range of the horn. The tweeter (treble unit) is responsible for the high-frequency sound, while the woofer (woofer) is responsible for the low-frequency sound. The division of labor and cooperation between the two can bring a richer listening experience.
| Speaker type | frequency range | Features |
|---|---|---|
| tweeter | 2kHz-20kHz | Crisp sound and rich details |
| woofer | 20Hz-2kHz | The sound is rich and powerful |
2. How to distinguish the high and low sounds of car horns
1.physical structure distinction: Tweeters are usually smaller in size and have thin diaphragms; woofer are larger in size and have thicker diaphragms.
2.Frequency response curve test: By testing the frequency response of the speaker with professional equipment, the performance of the tweeter and woofer can be clearly distinguished.
3.Hearing sense distinction: Play music of different frequencies, with the tweeter performing brightly and the woofer performing deep.
| Distinguishing method | Applicable scenarios | Advantages and Disadvantages |
|---|---|---|
| physical structure | preliminary judgment | Simple and intuitive, but not precise enough |
| frequency response curve | Professional debugging | High accuracy, requires equipment |
| Hearing sense distinction | daily use | Highly subjective and dependent on experience |
3. Suggestions for matching high and low sounds of car speakers
1.Use of frequency divider: The crossover can distribute the audio signal to the tweeter and woofer according to frequency, ensuring that each can perform its duties.
2.Power matching: The power of the tweeter and woofer must match to avoid sound quality distortion due to uneven power.
3.Installation location: The tweeter is usually installed on the dashboard or near the A-pillar, and the woofer is installed on the door or trunk.
| collocation elements | tweeter | woofer |
|---|---|---|
| Power range | 10W-50W | 50W-200W |
| Installation location | Instrument panel/A-pillar | door/trunk |
| crossover point | 2kHz or above | Below 2kHz |
4. Hot topics on the Internet in the past 10 days and hot topics related to car horns
1.Electric car audio upgrades: With the popularity of electric vehicles, car owners have higher and higher requirements for audio quality, and the matching of tweeters and bass speakers has become a hot topic.
2.DIY car audio modification: Many car owners try to modify the sound system by themselves, and the selection and installation skills of tweeters and subwoofers have attracted much attention.
3.Intelligent frequency division technology: New technology automatically adjusts high and low bass output through AI to improve sound quality experience, becoming a new trend in the industry.
5. Summary
The distinction between high and low sounds in car speakers is not only related to sound quality performance, but also involves installation and debugging skills. Treble and woofer speakers can be effectively distinguished through various methods such as physical structure, frequency response curve, and sense of hearing. Proper matching and installation can significantly improve the listening experience. Hope this article can provide you with valuable reference.
