Is the car audio not as good as Hi-Fi audio?
Text / Western Electric Standard
Our post-70s generation, witnessed China's leap from poverty to well-off, China began to reform and open up in the eighties, we are still carefree children, every day the school teaches you to learn to understand mathematics, physics and chemistry, all over the world are not afraid, there is a national highway next to the school, two-lane asphalt road, a summer can melt the asphalt, can stick to the bicycle tires so that you can not step on so exaggerated. As soon as we ran to the side of the road after school, waiting for a Jiefang brand truck to pass by, so we opened our mouths to breathe in the waste smell of the truck, and directly absorbed the exhaust gas poison, before we started to play other games, now I think about it, it was really silly and cute, but no way, in those days, cars were rare, as rare as pandas, and even the exhaust gas emitted became so valuable. To the nineties to learn to drive, the parents suggested to learn to drive a truck, even if you can't study in the future, just rely on being a truck driver, you can also live a good life, in the nineties truck drivers belong to the high-income group, if you say to drive a truck, is a high labor intensity of work, that drive a truck in the nineties manual transmission, every day is like a fight, at that time to learn to drive the liberation brand truck, not only the steering wheel only mechanical assistance, but also two feet clutch, that is, no matter you enter the gear, you must first step on a foot clutch before entering the neutral gear from the 1st gear, and then step on a foot clutch, only from the neutral gear into the 2nd gear, the same is true for the retreat, the result is to drive the truck down for half a day, the whole body is soreAt that time, the pure domestic car was really unsatisfactory, a small repair in January, a major repair in a quarter, my Changan is like this, so that after repairing, I will repair the car, and then change to a Hafei car is better, all Mitsubishi engine and gearbox, the overall quality is much better. It took 180,000 kilometers to enter the factory to repair the piston ring, and in the 90s, Japan's Mitsubishi had the most profitable business to sell engines to Chinese automobile factories.
Although the fuel car was invented by the Germans, it is the strength of the Americans to become bigger and stronger, but the fuel consumption of American cars is huge, and the interior is really not flattering, it is a machine that can run. This makes the German car with a high taste market for the appearance design and interior taste, and the Japanese car has sprung up after the Sino-American and Korean wars, and the Japanese car is not as strong as the American car, but it is fuel-efficient, and it does not have the high-quality design of the European car, but it is durable. Fuel-efficient and durable Japanese cars quickly occupy the global family car market, and the vast majority of consumers, for the sake of fuel economy, can only endure the Japanese that save to nine bags of elder-level interiors, is there a car? Can it be as fuel-efficient and durable as the Japanese car, the American car is so strong, and the German car is so tasteful and luxurious in the interior? It wasn't until the emergence of China's electric vehicles after the epidemic that you finally saw the emergence of this three-in-one perfect car, a 400,000 electric car, which can reach more than 500 horsepower of 2 million fuel vehicles, accelerate from 0 to 100 kilometers, and enter the 4-second club, which is extremely strong. Charging at night and driving during the day, the cost of 100 kilometers is about 30 yuan, which is much lower than that of Japanese cars with fuel economy as the benchmark. Finally, its luxurious calfskin interior, with surround sound sound, large-screen car theater, and fully intelligent voice-activated AI system. Its interior is luxurious and intelligent, far exceeding that of European million-dollar luxury cars. An era of truly enjoying the car life has finally begun.
I have to say that the on-board AI audio function of the electric car is very powerful, what music you want to listen to, you only need to say to the on-board AI, it will be downloaded from the network immediately, played to you, no matter where you sit, the AI system can adjust your seat to the emperor's seat, so that you can listen to the concert as if you were immersive. But in fact, how does the car audio of 400,000 mid-to-high-end electric vehicles compare with the HIFi audio played by our audiophiles? First of all, a 400,000 electric vehicle, excluding the net profit of 50,000, minus the miscellaneous taxes of 50,000, the remaining 300,000 is the manufacturing cost, and then subtract labor, equipment loss, and the development cost sharing removes 100,000, the 400,000 electric vehicle pure electromechanical mechanical part costs about 200,000, minus the most expensive battery, the motor part is about 100,000, and then subtract the body, seats, glass, interior, tires, etc. about 60,000, and the cost of the remaining AI audio system is compressed within 30,000. Subtract the cost of the AI system, and the cost of the network player, power amplifier, and speaker left for the car audio can't last more than 15,000 yuan. In home audiophile, the investment of 15,000 is not even the entry threshold. But in fact, I think the sense of listening to the car audio on the ideal L9,Weilai,Audi electric version Q5 I think it's quite good,Basically, it can compare with the fifty or sixty thousand family fever stone machine system,Why make such a conclusion,Because like us, the old burn who is used to listening to the old gall machine,Whether the music is warm or not,Especially the human voice,It must be rich and thick,And these are difficult to do with the stone machine,Even if it is a class A stone machine, it is not satisfactory。
Don't compare with the high-end gall machine, the high-end car audio is already a good sound system, and basically do not need to be adjusted, the clarity of the sound quality, delicacy, details and sense of speed are good, then I just said that the cost of more than 10,000 car audio and 50,000 or 60,000 home audiophile is about the same, that is not very value-for-money? In fact, the family of 50,000 or 60,000 brand-name audiophile, the production cost is more than 10,000 only. If it is a miscellaneous audio of three or four lines, the cost will be lower, but it is a handmade audio of the earth cannon, the cost will be relatively higher, a set of earth cannons that sell 60,000, the cost of more than 30,000 is a normal thing, but the soil cannon audio lacks brand value support, and it will be more difficult to change hands. Speaking of car audio, obviously, the cost of 400,000 car audio is basically the same as that of 50,000 or 60,000 family audiophile. However, the sound quality is more advantageous, because the listening method of car audio is more like the near-field listening gameplay of large headphones, and the distance from the ears of passengers in the car to the speaker is 1 meter to 1.5 meters. It's very close, like bringing a large headphone on the head, so that the close listening experience is more detailed. Due to the narrow space in the car, to manufacture low frequency, it is necessary to rely on the low-frequency resonance tube similar to the headphone, so unless the car audio has been specially modified, otherwise, the low frequency is the kind of pipe resonance low frequency, there is a sense of submersible power, and there is no sense of hierarchy, and the low frequency is particularly mixed. But it doesn't matter, the vast majority of drivers who listen to car audio listen to human voices, so the adjustment of the middle and high frequency bands has become a top priority. Due to the limited power amplifier power of the car audio, the modern car speaker uses neodymium magnets, the sensitivity is higher, a few watts can be pushed very loudly, the sound quality of the neodymium speaker is very clear, a little cold, for the rumbling car environment in the driving, this is an advantage, and the family environment is generally quiet, too cold and glamorous sound is very unbearable.
And home audiophile can also use big headphones to play,You can also put a pair of speakers at a distance of two meters from you to listen,It will indeed greatly improve the sound quality and clarity,I have done many experiments,As long as it is not higher than 1.5 meters, the box can play better。 But there is a downside to this gameplay, there is only one emperor position, and you are the only one who can enjoy the music. Other friends will have no sense of sound field when listening to it from a distance, and there is a disadvantage of the big headphone game called the brain concentration effect, the instrument and the human voice are concentrated in the top of the brain, and the positioning separation is difficult to fine-tune. In addition, the playability of home audiophile audio is much higher than that of car audio, such as opening tape, vinyl machine, cassette player, CD player, DAT machine and so on. In addition, the value retention of home audiophile is much higher than that of car audio. A set of 100,000 yuan of home audiophile audio after 5 years of play is still about 50% of the residual value, and a set of 100,000 yuan of car modified audio, after playing 5 years of dismantling the residual value of only 10%, if it is a sale of the car, it is basically given.
I remember a few years ago, there was a burner, specializing in using a second-hand imported car amplifier to install an aluminum alloy shell, add a 220-volt variable 12-volt power supply in it, modified into a fever amplifier, everywhere to find a famous machine to fight in the ring, I heard that I also won a lot of famous machines, although I have not tried this myself, but I also feel that it is defenseless to play, in fact, I also bought a lot of imported fever second-hand car amplifiers back to modify their own cars many years ago, at that time, these second-hand car amplifiers were mostly McJingtu, Harman Kardon, Bose, Yan Feilis, and MacLee Clouds, etc., of course, it is still the most expensive MacLego and Berlin Sound, and the sound is also very clean and organized, but I still bought McInto's water blue lake meter car stereo, because it was so good-looking, but at that time, most of the second-hand imported audiophile car power amplifiers were very cheap, but they were absolutely full of materials, and the power tubes were all imported goods that were replaced by fakes, and the circuit board technology was by no means comparable to the later copycat factories. Buy such a car power amplifier, with a 12-volt power supply and an aluminum alloy shell, the cost is more than a thousand points, there should be a good performance, if not the pursuit of the old guts of the ancient tomb school, such a way to play, it is also a shortcut to fever, anyway, the expenditure is not large, and you can play imported brand-name goods, for example, two or three thousand can get the rear end of the car of the McRie Yunxun, it is still very cost-effective.
