Steam Daming: Stop calling me to supervise the country

Chapter 137 Phone
It snowed again in the sky. There are many snow days this year, and the snow in the south of the Yangtze River is cold.

It's just that the New Year is approaching, even if it is as cold as in an ice cellar filled with water, it is still necessary to say auspicious words such as auspicious snow and a good year.

Zhu Zhanchang was unhappy. A few days ago, he was told a lot by the censors in the early morning. He acted unethically, acted recklessly, and acted recklessly. Even Zheng He was said to be an accomplice.

Fortunately, several bigwigs in the court helped to speak, and they were beaten when they returned to the palace. As long as Zhu Zhanchang didn't talk back, the matter would be over in a few days.

Holding the latest edition of the newspaper in his hand, it wrote about the Zhoushan naval battle. It has been shown to Zhu Gaochi, and it will be published tomorrow with permission.

I touched the material of the newspaper, and the material of the newspaper is improving.

Newspapers can be profitable, and the profits are not cheap. With the blessing of profits, Lin Miao spends more money on improving the material of the newspaper itself, and also improves the manufacturing process of paper products from a side perspective.

Newspapers and food stamps both require paper, and as long as there is profit, someone will bother to study it.

"It's really good that Li Shimian wrote two articles, and this publication must be exciting again." Zhu Zhanchang praised.

According to Di Bao’s report on the Zhoushan naval battle, Li Shimian made some polish, emphasizing the cruelty of pirates, beheading women and children. The people who watched the battle were furious and the naval battle was won, and the people who watched it were full of enthusiasm and what the people wanted.

"The overseas barbarians of Dongying often use ronin pirates to harass my coastal villages and towns, burning, killing, and looting. Everyone is like this, how dare the Japanese pirates?"

How dare a Japanese pirate?enough.

At this time, Xiaosheng brought in a better-made generator, which was made by Zhang San and others. It can generate electricity when shaken, but carbonized bamboo silk is still not enough.

The carbonized bamboo silk is like a small group of men with only a hard mouth in the whole body. They say that they are only in poor condition. In fact, they can only last for so long each time.

The principle of power generation is not difficult, but the storage and use of electricity is a bigger problem.

The most common electrical products Zhu Zhanchang thinks of are lights and telephones.

If the materials needed for light bulbs are now hard to come by, telephones seem to be fine.

The principle of the telephone is naturally more complicated than the electric light, but the materials required are not so complicated.

Of course, the telephone here certainly does not refer to the modern dial-up telephone, but the old-fashioned microphone telephone.

Have you ever played a phone game with two water cups tied with ropes in kindergarten?

Turning a cord into a wire, a drinking glass into an earpiece and a microphone with a diaphragm and electromagnet, this is the simplest telephone.

When the speaker picks up the phone and speaks into the microphone, the vibration of the vocal cords excites the air to vibrate, forming sound waves.

The sound wave acts on the microphone, which drives the diaphragm to vibrate, and the diaphragm vibrates in contact with the electromagnet to generate a constantly changing electrical signal, which causes it to generate a current, which is called voice current.

The changed electrical signal is transmitted to the electromagnet in the earpiece through the line, and the electromagnet causes the iron sheet to generate corresponding vibration to knock the diaphragm in the earpiece.

Then the sound is produced.

As long as there is electricity, it can be used as an electromagnet. The main key to the microphone and earpiece is the material of the diaphragm. The current cannot be stored, so it needs to be shaken to generate electricity to maintain the current.

Zhu Zhanchang wanted to try making a phone, but because he couldn't get to Zhang San's workshop, he had limited tools and had to rub it by himself.

After all afternoon, Zhu Zhanchang could only give up the copper sheet to make the microphone because he had no welding ability, and cut off two chair legs abruptly.

Tie the cloth as tightly as possible.

Seeing that it was getting late, Zhu Zhanchang wrapped two pieces of iron around a copper wire. According to the right-hand spiral rule, an electromagnet could be made by turning on electricity.

An iron piece is placed between the electromagnet and the microphone diaphragm, and the iron piece will drive the diaphragm to vibrate according to the current change of the electromagnet.

Zhu Zhanchang started to do the experiment. Chu Er took the receiver to the outside of the yard. The receiver and electromagnet of the microphone were fixed on the wooden board to avoid shaking.

With Zhu Zhanchang's gesture, Xiaosheng began to shake to generate electricity.

He shook it very carefully, keeping the speed as constant as possible to avoid instability of the current.

Zhu Zhanrong pursed his lips and said into the microphone.

"Did you have meal?"

"I heard it, I heard it, Your Highness." Chu'er exclaimed from outside the yard and ran in.

Although the sound quality is very bad, almost total loss of sound quality, but I heard it, I really heard it.

Zhu Zhanchang said a word in a normal voice in the yard, and Chu Er heard it through the receiver.

"It's amazing, Your Highness."

Seeing Xiaosheng eager to try, Zhu Zhanchang handed them the microphone and asked them to try it.

The eunuchs and the maids all took this rare thing carefully and tried it out, and everyone took turns listening outside.

Passing by, Hu Shanggong looked curiously at this group of noisy palace maids and eunuchs.

"Hushang Palace."

"What are you doing?"

"This is a newly invented telephone by His Royal Highness. People are talking inside. Through this receiver, I can still hear it from so far away."

"Oh? There is such a miraculous thing."

Hu Shanggong slowly walked into Zhu Zhanchang's courtyard. At this time, Zhu Zhanchang was standing in the courtyard, and the young man in the light white snow was already in full bloom.

It's just that Hu Shanggong remembered the scene when he rubbed the ointment for His Highness that day.

Your Highness is very beautiful.

"His Royal Highness." Hu Shanggong bowed and saluted.

"Hu Shanggong, you don't need to be more polite. When there are no outsiders in the future, don't stick to these etiquettes."

"That can't be done. If you lose your manners, His Royal Highness and the Crown Princess will punish you."

"You are not an outsider, no one will tell."

It's not an outsider, it's an insider.

"His Royal Highness, your newly made telephone is very magical. How can you transmit people's voices."

"The principle is more complicated, I'll tell you next time, I was just watching Hu Shanggong running around every day to send messages to his father and mother, and it was quite tiring. I thought that if it was possible to send messages from a long distance, it would be good, so that Hu Shanggong would You don’t need to be tired of running around like this.”

Hu Shanwei was surprised. Looking around, the eunuchs and maids were watching the phone, and no one paid attention to the conversation between the two of them.

"His Royal Highness can miss Shanwei, and Shanwei is flattered."

Zhu Zhanchang smiled: "Of course I miss Hu Shanggong. Recently, I still feel a little sore in my buttocks. Hu Shanggong's ointment works very well. You can rub it for me next time you have a chance."

"Follow your orders."

Hu Shanggong was still very busy, so he said hello and left.

"Bring Xiaosheng's things with me to the study of the East Palace."

"His Royal Highness, are you still going to talk to His Royal Highness about leaving the palace?"

"Of course, I can guarantee that my father will absolutely allow me to leave the palace this time, and even send me out of the palace overnight."

This time, he accurately grasped the needs of users.

After all, how could a fat man who is diligent in political affairs but not in good health refuse the opportunity to notify everyone in bed and work while lying down?
