How about going home with a car horn?

Car audio and home audio are both audio systems, and the principles are roughly the same, which leads some people to think that there is not much difference between car audio and home audio, and some even buy their own car audio and install it like home audio. If you can put on a good sound quality, you can only say that a blind cat has met a dead mouse. When choosing to install home audio, you only need to consider the quality of the speaker, the matching degree of the room and your own preferences. As for the car stereo, you should not only consider the quality of the horn, but also consider whether it conforms to the configuration, installation technology and tuning level of the car. Next, let's talk about the difference between car audio and home audio.

Different in appearance

At most, a beautiful voice coil is added to the appearance of the car speaker, and a speaker pad is added during installation, while the home speaker is boxed to eliminate the sound short circuit of the speaker unit, suppress its sound vibration, broaden its frequency response range and reduce distortion. Why is the car horn not in the box? The position of car horns is mostly unsatisfactory. Home speakers can be installed in speakers, with fixed volume and good stability. However, due to the vibration of the metal plate and sealing strip of the door and other sundries in the door, it can not meet the basic requirements of using the speaker.

Different designs

Automotive 12V power supply, the current of domestic 220V car is relatively limited, so car audio needs low voltage, low current and low impedance design. The horn power of car stereo is relatively small. The original car stereo is basically around 10-20W, while the speaker of home stereo is usually above 50W, which is suitable for matching speakers.

The use environment is different

Household stereos are generally used at room temperature, with relatively large empty rooms and relatively free speaker positions; The car stereo should be able to withstand the temperature range of MINUS 20 degrees to 80 degrees. Compared with the home audio used at room temperature, the requirements will be higher. Due to the empty space in the car and the anti-seismic requirements, car audio usually needs to be lightweight and integrated, which is more accurate than home audio. Generally, the location of car speakers is on the door and dashboard, which is very different from home audio. Car audio needs special sound field design.

Different brands

Automotive acoustics has been developed abroad for decades and has become a professional and independent field. Therefore, the brand awareness established by consumers through home appliances is only a marginal ball in the field of car audio, far from reaching the mainstream of car audio. If you want to have a correct understanding of car audio, you can consult the technicians in the automobile industry.

There is no real emperor position in the car, and there will be deviation in any position. The seat back will directly block the sound waves, and the speaker position is too low to be flush with the human ear. If the car stereo you buy is more expensive than your home stereo, that's normal.
