Today, many Mercedes-Benz, BMW and other high-end cars, the number of speakers on the original car is very large, and the layout is in different places. The average model is controlled by the manufacturer to control the cost of the whole vehicle. There are usually only four speakers on the car. The sound field is chaotic, the distance between different speakers is different, and the sound size is unbalanced. The layout of many speakers in the high-end models is to prevent this sound size. The sound field is balanced to achieve a surround effect.

When we talk about car audio effects, we often mention that many amplifiers or mainframes can create stage (stereo) and surround effects.

The so-called surround is the sense of the surround of the listener who has a sound, and can clearly distinguish the sound from all directions. In the current two-channel case, only "SRS" has this effect, but this has little to do with delay. The speakers on high-end models are generally multi-channel systems, such as dts, AC3, LOGIC7, etc., and also have two-channel stereo expansion, such as Dolby, LOGIC, Dolby, LOGIC II, CS-AUTO and other virtual extensions. Basically equipped with a center speaker CENTER.

Although the surround effect is a multi-channel system, not every speaker has the same sound. Each channel has its own division of labor, and then into your ear, although you hear a whole The music, but the different sounds from each channel are combined. The easiest thing is to go to the cinema to listen to it. The stereo is the same, but the two channels are different.

Also, surround sound and stereo are two different things. Overall, surround sound is suitable for watching movies, and stereo is suitable for listening to music. In the entire audio industry, surround sound can meet the listening requirements of a large number of people, and the surround sound system has advantages in the car. It is easy to make every seat listen to almost the same, it feels like an emperor. Therefore, high-end cars are used.

Stereo wants to be emperor is very difficult, no matter what music, the same music signal will sound in the center speaker, this is the emperor, no matter where you sit in the car, you can understand the sound from Out of the middle of the instrument panel. If you are a real music lover, listen to the stereo sound that is more expensive than a Rolls-Royce car, you will find that the surround sound is really not good, so count the audiophiles to change the car audio. All are stereo.
