Chapter 1689 Campus Broadcast!
"Qing Que, what are you and Zifan doing~?"
In the courtyard in the deepest part of the workshop, Li Zexuan walked into the house and asked Li Tai who was holding a tube-shaped object and shouting.
And behind him were Sun Zifan, Qin Huaiyu, Li Huairen, Yuchi Baolin and others. Only after Qin Huaiyu came to "report the letter", Li Huaiyu and Yuchi Baolin also ran here from all corners of the workshop.
"Oh! The mountain leader is here?"
Li Tai heard the voice and quickly put down what was in his hands, turned around and looked at Li Zexuan, "Shanchang, we succeeded! Our experiment succeeded~!"
Standing next to Li Tai was Mo Chui from the Department of Physics of the Academy. He was not only a candidate for the next generation of giants of the Mo family, but also a technical backbone of the Yanhuang Academy's "Killer Project". At this time, he was also excited.
Li Zexuan heard the words and said in a daze: "Qingque, what has succeeded? Are you talking about the loudspeakers outside?"
"Yes, yes! Just those speakers!"
Li Taimeng nodded, then he picked up a drawing, walked quickly to Li Zexuan, and said in high spirits: "Shan Chang, you told me that there are two ways to improve the phone, one is inside the phone. Add a filter circuit to filter out interference noise and make the sound clearer; another is to add a signal modulation and demodulation circuit to reduce signal attenuation, so that the sound can travel farther.
Later, I thought about it. The second method is more complicated and requires a long time of research. So I have been thinking about trying the first method in the past few days. I tried many filter circuits with different parameters and wanted to change the phone’s The voice is adjusted more clearly, and now it seems that we are almost successful! "
"That's it!"
Li Zexuan understood it instantly when he heard it. He squeezed his chin and nodded and said: "Well! I heard it outside just now. This voice is much clearer than before. This improvement you made is really useful~ Um! Not bad, not bad! Qingque, your hands-on ability is very strong!"
"Hey! Thanks to Mr. Mo Chui and Zifan for their help!"
Li Tai was a little proud of being praised by Li Zexuan. Suddenly, he remembered something and said, "Oh, yes, Shan Chang! We did this not simply to improve the telegraph. I want to install this thing on Every corner of the academy, in this way, whenever there is an important thing in the academy and want to inform the students and teachers, it can use this to convey the matter to every corner of the academy, which is much more convenient than before! Long, do you think this works~?"
"Huh? Install this thing in the academy~?"
Hearing this, Li Zexuan's heart suddenly moved. According to Li Tai's words, wouldn't it be equivalent to installing a cable campus broadcast for the academy? After that, wouldn't it be possible to organize a broadcasting station in the academy? Thinking of this, Li Zexuan glanced at Li Tai in surprise, secretly saying that this little fat man's thinking is still quite advanced!
"Yeah! Yes! It just so happens that the academy has already been powered on, and it’s just right to install this thing! Oh, let’s call this thing cable broadcasting from now on! After all, this thing is only used for short-distance transmission of information, and the function is still The telephone is different!"
After a pause, Li Zexuan came back to his senses, looking at Li Tai with admiration and said.
"Cable broadcast? It is widely spread, and the name Shan Chang is good~!"
Mo Chui on the side, a gleam of light flashed in his eyes at this time, he smiled and arched his hands.
"Hehe! I think the name Shanchang is good too! If that's the case, let's call this thing cable broadcast from now on!"
Li Tai didn't have any opinion on this name, he smiled and said.
Li Zexuan looked at the experimental table full of various machines behind Li Tai. He straightened his face and said:
"Qingque, whether it is a telephone or a cable broadcast, it is not a very urgent matter. Right now, your most urgent task is to build two telegraph relay stations in Binzhou and Yunzhou! The gentlemen of the college have been here for the past two days. I was busy reviewing the admissions test papers. When the Academy releases the list tomorrow, the teachers and students in the Academy’s "Killer Project" will have to go north, and the two telegraph relay stations must be built and debugged within three months! "
To be honest, Li Zexuan’s campus broadcast by Li Tai did surprise Li Zexuan, but it was only a surprise. He understood that the current national war was imminent, and inventions like cable broadcasting that only increased the entertainment of life were irrelevant. The words are very good, if not, it will not affect the daily life of the people of Datang.
But the telegraph relay station is different. This thing is related to the situation of the war between the Tang Dynasty and the Turks a few months later, and it is related to the lives of thousands of people in the Tang Dynasty, so Li Zexuan had to worry!
Li Tai said with a solemn expression at this moment: "Shanchang, Tai does not dare to forget the mission of the telegraph relay station. A few days ago, I ordered the craftsmen to start producing the components needed for the construction of the telegraph relay station and the steam engine needed for the construction of the thermal power station. Things can only be made in workshops, but not in other places! As for this cable broadcast, it is completely what we did in our free time. I hope to install it in the academy before going to Taiyuan. This will not affect the telegraph relay station. Construction progress!"
Li Tai’s words are right. Whether it’s a telegraph relay station or a thermal power station, it is technology that is beyond this era, and only the new workshop of Qiquge can barely make the components needed. There are not only highly skilled craftsmen in the workshop, but also some machinery and equipment that are not available elsewhere!
It is no exaggeration to say ~EbookFREE.me~ Qiquge's new workshop can fully represent the most advanced production technology level today!
Mo Chui also interrupted at this time: "Shan Chang, Qingque is right. The workshop has already gathered a group of top craftsmen. They are rushing to make the necessary utensils for relay stations and thermal power stations. It is expected that they should be able to be made the day after tomorrow. As long as the initial test is successful in the workshop, we can take these things to Bingzhou and Yunzhou~!"
Li Zexuan breathed a sigh of relief when he heard the words, and said, "That's good! The day after tomorrow, after you have successfully tested in the workshop, you should leave immediately! This time Mr. Mo will have to preside over the construction of the mountain guard and the medical school in Yunshan. , I really can’t get out of your body, Mo Chui, you will work hard, and go with Qingque! The teachers and students in the Academy’s "Killman Project" can be dispatched by both of you. In addition, Qingque, you can apply to your Majesty for a team of guards , Personally you to Binzhou and Yunzhou to avoid accidents~!"
Mo Chui and Li Tai answered one after another: "Yes! Shan Chang!"
Li Zexuan nodded and said, "Well! Keep busy, I'll go to the steel mill!"
