As for the wired phone, Zhuge Liang didn't even know what the phone was, what it was used for, and what it looked like.
However, when Zhuge Liang heard the term telephone, he also concluded in his heart that it must have something to do with electricity.
The matter of the steam engine has already shocked Zhuge Liang's heart, and now he is going to be in contact with the electricity. How can such a situation not shock and excite Zhuge Liang?
Afterwards, Cao Ang explained the situation to Zhuge Liang, and Zhuge Liang was very shocked by such a thing.
What Zhuge Liang didn't expect was that the sound could be transmitted through electromagnetic power. Such a situation is simply unheard of. Not only that, the transmitted sound can even be transmitted thousands of miles away.
Such a situation really shocked Zhuge Liang's heart.
Sound transmission thousands of miles away, such a thing is unthinkable for Zhuge Liang, but now the prime minister Cao Ang actually told him that all of this can be realized through electromagnetic, and such a thing, the object is a wired phone.
How could such a situation not shock Zhuge Liang?
Afterwards, Zhuge Liang also said with emotion in his heart: "If such a thing can really be researched, it will be a complete change for Xudu and the people of the whole country. This thing is really useful !"
Zhuge Liang was very shocked in his heart. This was his first contact with the phone. After he understood its purpose, Zhuge Liang was very shocked in his heart, that's why he said those words.
But now that Prime Minister Cao Ang entrusted Zhuge Liang with such an important matter, Zhuge Liang was very nervous at this time, and felt that he had an uncontrollable excitement directly rushing out of his body.
Seeing Zhuge Liang's excitement, Cao Ang smiled and said: "This is a long way to go, it is really difficult to realize such a thing, but now this matter is not in a hurry, it needs to be done step by step! "
Chapter 467 Making a Gramophone
"The telephone is only our ultimate goal. It is still difficult to create a telephone now, so we should start with something that is relatively easy to use, and then feel the mystery contained in it, which may be useful for our future research. helpful!"
Of course Cao Ang knew that it was very impossible to research the phone under the current situation, but now he had to choose an easier one to start with.
After Zhuge Liang heard Cao Ang's words, he also agreed very much, and then nodded, and then agreed with such a thing.
"Since we are studying something that is relatively easy to use, what should we study?"
Zhuge Liang then asked with some doubts.
Zhuge Liang was not afraid of difficulties, but he felt that what Prime Minister Cao Ang said was very correct. If he could start researching from a simple and related thing, and find some principles and rules from it, such a thing would be very good.
Not only can I indirectly feel about the production of the phone, but also I can accumulate experience and methods to pave the way for the production of the phone.
Cao Ang heard the words, and then said directly: "Since we are looking for a related and relatively simple one, let's start with the phonograph!"
Cao Ang also had some thoughts in his heart. It is too difficult to make a wired telephone now, but in the current situation, if he can make a phonograph first, he can also understand some other laws or rules. Category.
And the next step is to attack the wired phone.
As he said that, Cao Ang brought up the idea of a gramophone.
Speaking of the phonograph, it is natural to introduce the phonograph. This phonograph is a very primitive sound playback device, which can play the stored records on the phonograph into the arc-shaped grooves carved on it, and then put the records Place it on a rotating platform.
Afterwards, you only need to put the stylus down, and the rotating turntable will drive the record to rotate, and then the stylus will pass through the arc-shaped groove of the record.
As long as the arc-shaped groove is drawn, the content in the record will be played and sound will be made.
This situation sounds magical, but the principle is very simple.
After the stylus passes through the arc-shaped groove, it will make a sound, because the speed and height of the sound can have a distinctive vibration, and such vibration will cause the stylus to vibrate accordingly.
It is such a principle, if this principle can be reversed, such trembling can also reverse the original sound.
There are a lot of grooves on the record, which are actually related vibration marks.
When the pointer is put up, the stylus will rotate along the planned pointer pattern, so that the pressing sound can be restored again, and then released again through the connected speaker, that is, the big speaker .
Such a situation is very simple and easy to understand.
As for why Cao Ang asked Zhuge Liang to study the phonograph, his purpose was to let Zhuge Liang make the phonograph by the way, because at this time, there are already entertainment activities, so the phonograph is a must.
In addition, another new year is coming, and Cao Ang has made a very detailed plan in his heart, that is, he wants to use some scientifically researched equipment to hold a completely different activity from before, to enrich the entertainment of the people Activity.
As for other aspects, it is because whether it is the telegraph, the phonograph, or the radio, telephone, or walkie-talkie, many of their technologies are common.
It is precisely because of this that Cao Ang chose a relatively easy phonograph as the research object.
As long as one of these technical difficulties is overcome, wouldn't the research on wired telephony be much simpler and faster?
It can be said that Cao Ang also spent a lot of thought in order to make this wired phone be researched.
After Zhuge Liang understood Cao Ang's intentions, he carried out this difficult task to the letter.
And Cao Ang is responsible for providing Zhuge Liang with methods and ideas.
What Cao Ang knew was only some methods and ideas. He didn't have any other situations in his mind at all, and he didn't even have that concept.
Under such circumstances, the requirements for Zhuge Liang are much stricter.
In fact, it is said that Cao Ang is responsible for providing ideas and methods, but this kind of provision is simply not provided. For him, Zhuge Liang, he needs to explore, research, and slowly overcome the problems!
However, for such difficulties, for this unknown difficulty, Zhuge Liang was not discouraged, but very decisive and brave, and there seemed to be no sign of retreat on his face.
Cao Ang was very pleased with this. Being able to train such a large number of scientific researchers is simply the most correct thing he has ever done.
It is precisely because of the investment in Nagwu College that so many smart talents are born, so many geniuses are born.
But also because of these geniuses, because of these talents, the scientific strength in Xudu is already very strong.
In addition, because of Cao Ang's influence, the imperial court provided them with considerable financial support for those who devoted themselves to science and research, so that they could live without worry and study hard.
Under the insistence of these geniuses, and under the solution of the court, Cao Ang believed very much that things like wired telephones would not wait too long at all.
And the phonograph that needs to be developed before that will not wait too long.
Before this year's New Year's Eve, all the results will definitely come out, and the use of the steam engine will be able to reach a very sufficient situation, and the power equipment will not be as good as when it was first used!
Such a situation is Cao Ang's idea, and if such ideas are combined and appear on that battleship, what kind of situation should it be?
When a battleship has the power provided by the steam engine, the blessing of the gunpowder weapon, and the communication equipment with telecommunications equipment, under such circumstances, what difficulties are there that can hinder the battleship?
Such comprehensive strength can even be directly traced back to the warships of the [-]th century. With such a huge difference in time, such warships are basically invincible in the current dynasty!
After everything was arranged, Cao Ang went home with peace of mind.
Chapter 468
Now all things have been developing in a positive direction, and Zhao Yun in that pass has not received a letter. The fact that this situation is true makes Cao Ang feel a little worried.
However, Cao Ang knew Zhao Yun's strength, so he was not very worried. There is no news so far, so he must be entangled in something!
Now Cao Ang can only think in this way, because he doesn't know the situation in Guanzhong.
