Chapter 330: Enthusiast's World

In the living room of Qiao Zihe's house, there really was a set of sound equipment that looked very complicated. What record players, tape drives, amplifiers, etc., and seven or eight speakers of different sizes are placed in every corner of the living room. The nameplates of these devices all read foreign languages, or English, or Japanese, and you can see that they are expensive exotic products at a glance.
Qiao Zihe took Gao Linqi to the amplifier, and he whispered to him, and the two turned on the audio for a few minutes. Gao Linqi nodded again and again, Qiao Zihe smiled with satisfaction and asked Qin Ling Beckoning: "Student Qin Ling, let's go to the piano room."
After that, he nodded to Qin Hai and Peng Tingting again, and said, "Then the two of you will be patient in the living room for a while."
Qin Hai and Peng Tingting naturally do not have any opinions, after all, the old man is teaching Qin Ling. After Qiao Zihe and Qin Ling entered the piano room and closed the door, Gao Linqi disassembled the large power amplifier and started to measure something with the multimeter he brought with him, muttering verbally.
Peng Tingting was bored, so he went forward to see Gao Linqi repairing the amplifier, and asked, "Hey, Xiao Gao, what did Professor Qiao tell you just now?"
Gao Linqi glanced at her and said, "Did you not hear it just now?"
Peng Tingting said: "I don't understand what you say, what low frequency, sensitivity, overtones, what do you mean?"
Gao Linqi gave her a blank look and said, "You don't understand music, it's no use telling you this."
"Gao Linqi, dare you talk to me like this, you are not afraid I told Xiaohong to go!" Peng Tingting raised her eyes. It is estimated that this little red should be Gao Linqi's goddess and Peng Tingting's girlfriend. Great killer character.
Sure enough, Gao Linqi's attitude softened and he turned on the recorder. I played a short piece of piano music that I do n’t know, and asked Peng Tingting: "Listen carefully, what do you think of this sound?"
Peng Tingting leaned her ears and listened to the stereo sound from the seven or eight speakers in the entire living room. She nodded her head and said, "Well, it sounds good. This stereo sound is better than our four speakers."
Gao Linqi said: "Did you not hear that the treble part is a bit inflexible? The resolution is not shown."
"Flexible?" Peng Tingting's eyes widened. "How can the sound be flexible?"
Gao Linqi's eyes were rounder than Peng Tingting's, and it almost felt more prominent. He rebuked: "How can the sound be inelastic? You listen to this one again, it's more gentle, you can feel the elasticity. ?"
Qin Hai was sitting next to looking at the magazine of Qiao Zihe's house. After hearing the conversation between the two, it was interesting, and he laughed and said, "Xiao Gao. This is a tough man for you. You are an audiophile. I and Tingting is not, how can you have such a good ear. "
When Gao Linqi saw Qin Hai interject, he was a little embarrassed, and said with a smirk: "General Qin is right, we enthusiasts are really dead. If you do n’t know how to listen to audio well, do n’t listen. After listening to it You can't listen to any kind of music. I think it's all noise. "
"I heard that the top enthusiasts pay attention to what electricity they use to play music." Qin Hai remembered an Internet joke from later generations and laughed at Gao Linqi.
Gao Linqi was an honest child, didn't understand Qin Hai's meaning, and asked obediently: "I don't really understand what President Qin said. What is the electricity?"
"For example, the sound of thermal power is warmer, the sound of small power is colder, but the resolution is high. In the firepower, the electric sound quality of Beilun Power Plant is the best. Because anthracite is burned." Qin Hai said.
"No ..." Gao Linqi thought seriously for ten seconds, and then saw the smile on Qin Hai's face, and couldn't help but realize that, and said with a smile, "General Qin is joking with me, I take it seriously."
Qin Haidao: "What kind of sound are you talking about? How do you understand it?"
Gao Linqi said: "This can only be said to be the feeling of ears, which is undeniable. However, you should know, Mr. Qin, compared to plastic speakers, wooden speakers are completely different in sound. Wooden The sound reproduction of the speakers is good, especially the effect of bass, which is unmatched by plastic speakers, you admit it? "
This statement is within the scope of Qin Hai's knowledge. People with a little appreciation can also hear the difference between plastic speakers and wooden speakers. He nodded and said, "I know this, isn't the effect of different wood different?"
"Of course." Gao Linqi seemed to find a consonant and said, "The sound is really too particular. What material the speaker uses and what material the speaker diaphragm uses will affect the sound quality. And this audio You can see that there are no silver wires, all of them are silver wires, and the signals transmitted by ordinary copper wires will be distorted. Of course you can't hear them, but those of us can hear them immediately. "
When he heard the word
material
, Qin Hai thought about it. He pointed to the equipment in the room and asked,
Xiao Gao, isn't this room's audio cheap?

"That's for sure." Gao Linqi said: "People like us usually say, whoever wants to hurt, let him play audio, high-end audio is a bottomless pit, how much money you have is not enough to fill in. President Qin, you Look at this speaker, imported from Japan. Guess how much? "
Qin Hai and Peng Tingting also looked at Gao Linqi's fingers at the same time, and saw that he was referring to a small speaker, which was half the size of a brick. Qin Hai knew that since Gao Linqi asked this way, there must be an amazing answer, so he didn't dare to answer it immediately. Peng Tingting had some strength in breaking the jar, and he opened his mouth and said, "Such a small speaker, can it be 200 yuan?"
"General Qin, what do you say?" Gao Linqi asked Qin Hai.
Qin Hai shook his head and said, "I can't guess, but I think it might be more than 200 yuan?"
"Multiplying by 20, a total of 4,000 yuan, this is because of the relationship." Gao Linqi said proudly.
"4,000 yuan! Hey ... hey, just such a small thing ..." Peng Tingting screamed like he was stomping on his feet, shaking his head, and an associate professor's monthly salary was more than 100 yuan. Such a small speaker costs 4,000 yuan, which is really unacceptable.
Qin Hai was also a little surprised, but he was also someone who had met some people in the world, knowing that the value of some things in this world could not really be seen from the outside. He asked Gao Linqi: "Xiao Gao, why do you say such a speaker is so expensive? What is expensive?"
"There's so much more." Gao Linqi saw that both Qin Hai and Peng Tingting were shocked by themselves, and he couldn't help but tremble. He pointed at the speaker and said, "The speaker in this speaker is the latest product in Japan. The diaphragm used is not a metal diaphragm used for general speakers, nor is it a common pp plastic diaphragm. It is a new material called a small density, good rigidity, and suitable damping. Film, it's worth thousands of dollars. "
"Are there any domestically produced diaphragms?" Qin Hai asked.
"Made in China?" Gao Linqi put his mouth as if eating bitter gourd. "How can there be made in China? Now, high-end audio can be made with domestic materials, all imported from abroad."
"Why can't domestic materials work?" Qin Hai grasped Gao Linqi's words and delved deeper.
Gao Linqi said: "How do I know, anyway, with domestically made diaphragm speakers, I can't listen at all. I can hear imported diaphragms as soon as I hear them. One cent is one cent, the other is expensive."
Qin Haidao: "Xiao Gao, you said earlier, the diaphragm material requires low density, high rigidity, and moderate damping. What else is required?"
"This is more, for example, the instantaneous response speed should be fast, high frequency can not appear resonance, pay attention to a lot." Gao Linqi is a good teacher.
Qin Hai smiled slightly and said, "Xiao Gao, what you said can actually be translated into some requirements in material design. Proper adjustment of the material formula can achieve these requirements. How about, I will find someone to develop the first-class vibration Membrane materials, as well as speaker materials, to hire you as an appraiser, you just need to tell us whether this material will work and which material will work best. We are working together to make a world-class domestic diaphragm, are you interested? "
"You?" Gao Linqi frowned, feeling that Qin Hai was a little overwhelmed. In his opinion, domestic companies are able to produce international second- and third-rate diaphragm materials, and they say that they are world-class. Is it possible for anyone to get world-class things?
At this time, Peng Tingting was firmly on the side of the boss. She knocked on Gao Linqi's head and said, "Xiao Gao, you look down on me, but you can't look down on me, Mr. Qin. Do you know, our thermal sprayer designed by Mr. Qin As well as ceramic knives, they are all world-class, and foreigners come to place orders. We President Qin said that what can be made will definitely be made. "
"What does a thermal sprayer do?" Gao Linqi asked.
Qin Haidao: "It's not an amazing thing, it's ~ EbookFREE.me ~ which is used to paint the surface of the machine. Oh, it's painted ..." Gao Linqi gave a disdainful response.
Qin Hai went on to say, "However, our thermal sprayer is the first in the world, so it entered the international market. Last year, the sales were not very good, and it sold more than 200 million US dollars."
"Two ... billion!" Gao Linqi was almost frightened and fell over. As an audiophile, he has seen many rich people, millions and millions of people, and he is quite respectful of him. , Because he can repair the sound of these people's home. But at first he heard a figure like hundreds of millions, and it corresponded to the US dollar, and his confidence finally collapsed.
"Qin ... General Qin, what are you talking about?" Gao Linqi asked.
"What are you saying?" Qin Hai asked.
Gao Linqi originally wanted to ask whether the so-called more than 200 million US dollars was true, but then he changed his mouth and said, "What you just said is to be a world-class diaphragm material, is it true? "(To be continued ...)
