Do you want to install a tweeter in the car

There is no need to add a frequency divider, because the capacitor is the frequency divider. Tweeter Introduction: The tweeter is the tweeter unit in the speaker. Its function is to replay the high-frequency signal (the frequency range is generally 5KHz-10KHz) output from the frequency divider.

The tweeter should be installed as close as possible to the human ear, such as on the A-pillar of the car or above the dashboard. Some models are located on the door, so that the sound field is basically equal to the human ear, and the owner can also better experience the charm brought by the music.

It's good to use bass, and a small car doesn't need a high-pitched horn. The sound made by the tweeter is high and thin, and the sound is sharp.The sound of the woofer is low and wide, and the sound is relatively deep.

If your requirements for audio are not so high, and the full-frequency speaker is not bad at the same time, it basically has no effect, but the distinction between high-level bass will not be so clear.

Which brand of tweeter is good?

Good tweeter brands include Sony, JBL, Yamaha, Walker, Harman Kardon, Soai, etc. Sony is a world giant in the fields of electronic 3C, games, finance and entertainment, and has one of the world's leading brand influence.

According to the query ranking list 123.com, JBL, Alpai, etc. have good sound quality tweeters. JBL's tweeter is very cost-effective, with a moderate price, perfect sound quality and good cutting stability, great value for money, and clear sound.

In fact, there is not much worse than any brand: the top brand is still BOSE in the United States and MarkLevinson; in addition, Jinlang, Hertz, MB, Dana, Lanbao and Bosch are all good audio brands; as for Sony, Panasonic, JVC, Alpai and Jianwu are all It's a good host brand. How about the stereo?

EDIFIER Walker, founded in 1996, is currently the world's second largest professional multimedia audio enterprise in China, focusing on the research and development of audio technology and product application.

What is the function of the tweeter in the car audio modification?

1. [Pacific Automobile Network] The function of the car tweeter is to restore the role of the high-frequency band of the track and express the delicate sound. The tweeter should be installed in a position that is level with the human ear as much as possible, such as on the A-pillar of the car, or above the dashboard. Some models are located on the door, thus forming The sound field is basically equal to the human ear.

2. [Pacific Automobile Network] The function of the horn on the car is according to the needs andIt is stipulated to issue the necessary sound signals to warn pedestrians and attract the attention of other vehicles to ensure traffic safety, and also to urge and transmit signals. The car tweeter is the tweeter.

3. First, reduce the distortion of the speaker output. Because the frequency response of the tweeter determines that it is only effective for high-frequency signals and not for low-frequency signals, if there is no filter capacitor, the low-frequency signal will also enter the tweeter together, and the tweeter will distort the output of the low-frequency signal. The second is the problem of power distribution.
