Where is the car horn

Two-frequency loudspeaker is widely used in the front sound field of automobiles. There are basically five basic installation methods in the modification, and the other methods not described are formed by some changes of these basic methods.
1. The tweeter and bass are installed on the pedal
This method can obtain ******* sound field and ******** imaging force in most car audio modifications. Due to the limitation of the car environment, the distance between the front audience and the left and right channels is seriously asymmetrical. For example, the audience sitting in the driver's seat is closer to the left channel speaker, and vice versa. Installing all tweeters and subwoofers on the pedals can make the distance between the speaker and the human ear the smallest. So as long as the debugging is proper, you can easily obtain the ****** sound field, such as the width and depth of the sound field, which will make you feel that the sound field exceeds the car body.
Of course, if adjusted improperly, the sound field will be very low, making people feel that the sound is coming from the bottom of their feet. However, as long as the correct angle and installation method are selected, this phenomenon can be completely avoided.
In China, this kind of modification method is relatively rare, because most domestic car audio refitters think that installing the speaker system on the pedal is very ugly, but it also hinders travel and is easy to stain or damage its protective frame.
2. The tweeter is installed on the pedal, and the bass is installed under the door panel
This installation method is basically the same as the first installation method, but this installation method makes the modification of the pedal more difficult to show, which can be said to be a compromise of the first modification method. Its advantages are the same as that of the first method, and it is easy for consumers to accept because the original car has little change. The adjustment of this modification method will also make the sound field width and depth very easy to obtain, but the sound field height is prone to problems.
3. The tweeter is installed above the door panel, and the bass is installed below the door panel
This installation method is very common in the car audio of the original car. Because there are few changes in the car interior, many car owners are easy to accept. This installation method will have better width and proper height for the sound field, but the depth of the sound field will be shallow, and the whole position of the sound field will be too close to the audience. In addition, due to the difficulty in adjusting the treble adjustment angle, the sound field compression is obvious, and the left and right width of the sound field is unbalanced.
4. The tweeter is installed on the instrument panel, and the bass is installed under the door panel
The tweeter is installed on the instrument panel, which is rare in the original car. In general, car audio modification is to dig holes in the proper position of the original instrument panel, and then fix the tweeter, or install the tweeter mold at the connection between the instrument panel and the a-pillar. This installation method can obtain better sound field height, depth and sound field position. However, this installation method requires higher requirements for loudspeakers, because the distance between the tweeter and the mid-bass is relatively far, which will lead to the sound disorder near the frequency division point and serious peak and valley, thus affecting the sound quality. Moreover, the deviation between the propagation direction of the tweeter and the propagation direction of the mid-bass is large, and the impact on the sound quality is very serious, which requires the speaker system designer to fully consider in the design process
In this modification, especially for the high tone with narrow band, the sound quality will be greatly affected. Generally speaking, this installation method requires that the pitch at the top of the ball should be at least 25 cores, while the pitch at the top of the ball should be at least 25 cores, while the pitch at the top of the ball should make the mid-frequency thinner, the vocal profile larger, and the image quality worse. In the active electronic frequency division, the frequency division point should be aligned with the lower limit as far as possible, so that the lower limit of treble and the upper limit of bass can be fully integrated.
5. The tweeter is installed on the A-pillar, and the bass is installed under the door panel
This modification method is the most common in domestic car audio modification. Generally speaking, the installation position of the treble is flush with the ear of the audience. According to the system configuration and the characteristics of the treble, there are many methods for the direction of the treble. The specific method will be introduced in the installation points of treble.
