It's snowing again in the sky. There are a lot of snowy days this year. The snow in Jiangnan is cold.
It’s just that the New Year is approaching, and even if it’s as cold as an ice cellar filled with water, you still have to say auspicious words like auspicious snow heralding a good harvest.
Zhu Zhanzhen was unhappy. A few days ago, he had been told a lot by the censors at court that he was acting unethically, recklessly and recklessly. Even Zheng He was said to be an accomplice.
Fortunately, several big shots in the court helped to speak up, and they were beaten when they returned to the palace. As long as Zhu Zhanzhen didn't talk back, the matter would be over in a few days.
He held the latest version of the newspaper in his hand, which wrote about the Zhoushan naval battle. He had already read it to Zhu Gaochi, and it will be published tomorrow with permission.
I touched the material of the newspaper and found that the material of the newspaper was improving.
Newspapers can be profitable, and they are very profitable. With the support of profits, Lin Miao spends money to improve the material of newspapers themselves, and also to improve the manufacturing process of paper products from a side perspective.
Newspapers and food stamps both require paper. As long as there is profit, someone will take the trouble to study it.
"Li Shimian wrote two articles that are really good, and this publication must have excited the public." Zhu Zhanchen praised.
According to the Di report of the Zhoushan naval battle, Li Shimian polished it to a certain extent, emphasizing the cruelty of pirates and beheading women and children. The people who saw it were furious. The naval battle was a great victory, and the people's sentiments were passionate and the people's aspirations were aroused.
"The barbarians from overseas in Japan often harass our coastal villages and towns with rogue pirates, burning, killing, and looting without hesitation. Our Ming Dynasty warships are strong and powerful, and our guardsmen are not afraid of death. Even our female relatives are not afraid of pirates. If the Ming Dynasty people
Everyone is like this, how dare the Japanese pirates?"
One sentence, "How dare the Japanese pirates?" is 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 the carbonized bamboo silk still does not work.
Carbonized bamboo silk is like a small part of a man whose whole body is hard but only his mouth is hard. It is said that he is just in a bad condition, but in fact he can only last so long every time.
The principle of generating electricity is not difficult, but the storage and use of electricity are more problematic.
The most common electrical products that Zhu Zhanchen thinks of are lights and telephones.
If it is difficult to obtain the materials needed for electric lights now, it seems that the telephone can do it.
The principle of a telephone is naturally more complicated than that of an electric light, but the materials required are not that complicated.
Of course, the telephone here definitely does not refer to the modern dial-up telephone, but the old-fashioned microphone telephone.
Have you ever played the telephone game in kindergarten where two water glasses are tied with a rope?
Turn the rope into a wire, and turn the water cup into an earpiece and microphone with a diaphragm and an 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.
Sound waves act on the microphone, causing the diaphragm to vibrate. The diaphragm vibrates and contacts the electromagnet, producing a constantly changing electrical signal, causing it to generate an electric current, which is called voice current.
The changing electrical signal is transmitted to the electromagnet in the earpiece through the line, and the electromagnet causes the iron piece to vibrate accordingly and knock the diaphragm in the earpiece.
In this way, sound is produced.
As long as there is electricity, you can make an electromagnet. The main key to the microphone and earpiece is the material of the diaphragm. Current cannot be stored, so you need to keep shaking to generate electricity to maintain the current.
Zhu Zhanzhen wanted to try making telephones, but because he couldn't get to Zhang San's workshop, he had limited tools and had to rely on his own hands.
After working on it all afternoon, because he had no welding ability, Zhu Zhanzhen had no choice but to give up the copper piece as a microphone and cut off two chair legs. The eunuchs spent a long time chiseling to make two earpieces.
Tie the cloth as tightly as possible.
Seeing that it was getting late, Zhu Zhanzhen wrapped two pieces of iron with copper wire. According to the right-hand spiral rule, he could make an electromagnet by applying electricity.
An iron piece is placed between the electromagnet and the microphone diaphragm. The iron piece will cause the diaphragm to vibrate according to the change of the electromagnet's current.
Zhu Zhanzhen began to do the experiment. Chu'er took the receiver outside the yard. The receiver and electromagnet were fixed on the wooden board to avoid shaking.
Following Zhu Zhanzhen's gesture, Xiaosheng began to shake and generate electricity.
He shook it very carefully, trying to keep the speed as constant as possible to avoid instability in the current.
Zhu Zhanchen pursed his lips and spoke into the microphone.
"Did you have meal?"
"I heard it, I heard it, Your Highness." Chu'er exclaimed outside the yard and ran in.
Although the sound quality is very poor, almost a total loss of sound quality, but I heard it, I really heard it.
Zhu Zhanzhen said something in a normal voice in the yard, and Chu'er heard it through the receiver.
"It's amazing, Your Highness."
Seeing the young students eager to try, Zhu Zhanzhen handed the microphone to them and asked them all to try it.
The eunuchs and maids carefully tried this rare thing, and everyone took turns listening outside.
Hu Shanggong, who was passing by, looked curiously at the noisy group of palace maids and eunuchs.
"Hu Shang Palace."
"What are you doing?"
"This is your highness's newly invented telephone. When people talk inside, I can still hear them through this receiver even though they are so far away outside."
"Oh? There is such a magical thing."
Hu Shanggong slowly walked into Zhu Zhanzhen's yard. At this time, Zhu Zhanzhen was standing in the yard. The young man in the light white snow was already full of heroism.
But Hu Shanggong remembered the scene when he applied ointment to His Highness that day.
Your Highness is very handsome.
"Your Highness, Fifth Prince." Hu Shanggong bowed and saluted.
"Hu Shanggong, there is no need to be too polite. From now on, don't stick to these etiquettes when no outsiders are around."
"That's not allowed. If you lose etiquette, Your Highness the Crown Prince and the Crown Princess will punish you."
"You are not an outsider, no one will tell you."
He is not an outsider, he is an insider.
"Your Highness, your newly made telephone is so miraculous that it can transmit human voices."
"The principle is rather complicated. I'll tell you next time. I was watching Hu Shanggong running around to deliver messages to his father and mother every day, and I thought it would be great if it was possible to send messages over a long distance, so that Hu Shanggong could
You don’t have to be so tired from running around here and there.”
Hu Shanwei was surprised and looked around. The eunuchs and maids were all watching the phone, but no one paid attention to the conversation between the two of them.
"His Royal Highness is thinking of Shanwei, and Shanwei is flattered."
Zhu Zhanzhen chuckled: "Of course I am thinking about Hu Shanggong. I still feel a little sore in my buttocks recently. Hu Shanggong's ointment is very effective. Please help me apply some ointment next time you have the opportunity."
"Shanwei obeys orders."
Hu Shanggong was still very busy, so he said hello and left.
"Brother, take your things and follow me to the study room in the East Palace."
"Your Highness, are you still planning to talk to His Highness the Crown Prince about leaving the palace?"
"Of course, I can guarantee that my father will definitely allow me to leave the palace this time, and he will even send me out of the palace overnight."
This time he accurately grasped user needs.
After all, how could a fat man who was diligent in political affairs but in bad health refuse the opportunity to inform everyone from his bed and work while lying down?
