Although the audio equipment is only a kind of auxiliary equipment for the car, it has no effect on the running performance of the car. But as people’s requirements for enjoyment are getting higher and higher, car manufacturers are also paying more and more attention to the car’s audio equipment, and use it as one of the contemporary standards for measuring car grades, so the technical points involved are always recognized by consumers. and the attention of fans. So, what are the technical points we should pay attention to? Read this article and let’s explore together!
1. Installation technology
Part of the car audio is installed on the main console of the car, and because the internal space of the main console is very small, this has extremely high requirements for the installation technology of the car audio, so a common installation has emerged internationally. Hole standard size, known as DIN (German Industrial Standard) size. Its DIN size is 178mm long x 50mm wide x 153mm high. And some more advanced car audio hosts are equipped with multi-disc CD audio and other devices. The size of the installation hole is 178mm×100mm×153mm, also known as 2 times the DIN size, which is more common in Japanese machines. However, some brands of cars have non-standard audio head units, and can only be specified to install a certain type of car audio. Therefore, when we purchase car audio, we must pay attention to whether the size of the audio host is compatible with the size of the mounting hole on the dashboard.
In addition to the size of the mounting holes on the instrument panel, the installation of car audio is more important to the installation of the entire audio system, especially the installation technology of speakers and components. Because the quality of a car’s audio is not only related to the quality of the audio itself, but also directly related to the installation technology of the audio.
2. Shock absorber technology
When the car is driving on a bumpy road, its vibration frequency will be greatly increased, and it is easy to resonate with the car audio speakers, greatly reducing the driving experience of the driver and passengers. This shows how important the shock absorber technology of the car audio system is.
3. Sound quality processing technology
With the development of research technology, advanced car audio achievements such as DSP power amplifier, DAT digital audio system and 3D surround sound system have gradually appeared in people’s field of vision. The editor here emphasizes that many car owners often ignore the importance of tuning when purchasing a car speaker set. Think about it, if the sight of a gun is crooked, is it possible for the bullets it shoots to hit the target?
There is a saying in car audio modification: “Three points depend on equipment, seven points on installation and debugging”, one can imagine the importance of installation and debugging, but different cars and everyone have different listening styles, and debugging is also different. A fixed standard parameter, generally speaking, it needs to be debugged according to the individual’s own situation. Familiar with the specifications of the equipment, operation and sound characteristics, as well as the various sounds produced by the combination of equipment, to debug the appropriate sound effect!
4. Anti-interference technology
Car audio is in a very complex environment, it is subject to electromagnetic interference from the ignition device of the car engine and various electrical appliances at any time, especially all electrical appliances in the car use a battery, and it will be affected by the power line and other lines. The sound is interfering. The anti-interference technology of car audio uses choke coils to filter the interference of the power line between the power supply and the audio, and uses a metal shell to prevent space radiation interference.
Encapsulation and shielding, anti-interference integrated circuits are specially installed in the audio system to reduce external noise interference.
5. Active noise reduction technology
While people are constantly pursuing the sound quality of car audio, they also put forward higher requirements for the use environment of car audio. Some manufacturers have applied active noise reduction technology similar to noise reduction headphones to the car environment. The active noise reduction technology neutralizes the noise through the reverse sound wave generated by the internal system that is completely equal to the external noise, thereby achieving the effect of noise reduction.
