Processing techniques for sound quality- Shengzhou Yusheng Electronic Technology Co., Ltd.

The sound quality processing of car audio has been developing towards digital technology. Advanced car audio with DAT digital audio, DSP (digital signal processor), MP3 technology, forming a digital, logical, high-power Hi-Fi stereo system. Car audio quality in addition to the host configuration, and the quality of the horn plays a very important factor. Some people think that in the general car stereo, the horn should at least account for more than half of the total investment. Because the manufacture of high-quality horn requires complex technology, the price is not expensive, but the high and low effects are often not achieved by the ordinary horn. Therefore, the car audio speaker is generally more exquisite, especially the multi-channel frequency horn is more so.

Car compartment space is limited, car audio speaker is impossible to bring a large speaker, this needs to adapt to local conditions to the use of instrument panel, door, rear partition and other components organically combined with the speaker, the formation of a kind of sound box construction principle, eliminate the sound wave superposition phenomenon. Of course, the horn installation position often affects the sound quality of the car audio effect, the same on the horn in different installation positions will produce different effects, so the installation position of the senior car audio horn to be determined after a variety of tests.

Anti-jamming technology

Car audio is in a very complex environment, it is at any time by the car engine ignition device and a variety of electrical and electromagnetic interference, especially all electric appliances in the car with a battery, but also through the power line and other lines to sound interference. The anti-interference technology of car audio adopts choke string to filter the interference of power line between the power supply and the sound, and adopts metal shell to seal and shield the interference of space radiation. Specially installed anti-interference integrated circuit in the sound is used to reduce the interference of external noise.
