Chapter 507: What are you doing?

Li Mu is considering how to solve the current dilemma of Zhao Guo. After walking around all night. He decided to accept Shang Wen's invitation and visit the State of Qin to see what changes had taken place in the State of Qin. At the same time, Zhao's first batch of overseas students arrived in Qin. Because of the Earthquake. Zhao Guo’s international students were stayed in Handan. Did not go to Qin country in time.

After careful consideration, Li Mu began to write to Shangwen. Tell the other party your itinerary and so on. The new situation between Qin and Zhao is changing in their private messages.

"Get up quickly." Ying Yu got up early and cried out, grabbing Shang Wen's ear with her hand.

"Ouch, it hurts." Shang Wen had to get up from the sofa.

"Let me go to bed earlier, I can't sleep at all." Yingyu's face was a little sleepy, but she couldn't sleep.

"Ah." Shang Wen stretched out and hit Hache.

"Get up, work, today I want to see the phone." Ying Yu cried.

"Oh." Shang Wen still replied in a daze. He did not wake up either.

"Get up quickly. Be careful. I splash you with water." Yingyu was washing herself under the service of the maid, which should have been avoided. But Yingyu thought in her heart that the two must get married. So I don't care at all.

Shangwen was still sitting on the sofa and beating Hache. By the way, think about how to do it on the phone. The telephone microphone converts acoustic information into electrical information because the carbon diaphragm squeezes the carbon particles to make the resistance change suddenly and small, so that a current that changes in strength according to the sound vibration is generated in the circuit, and the sound signal becomes an electrical signal. . Then spread it out.

The telephone device is very simple. It is a permanent magnet. Fortunately, not much demanding. If a large magnet is required, it cannot be produced anyway. At the same time, Shangwen solved the problem before, and the appearance of the phonograph was originally after the phone. Because the toner microphone of the phone borrows the carbon microphone in the phonograph. This invention reduced the difficulty of making telephones for Shangwen a lot.

Shang Wen got up and started to make a phone, his mind was full of phones. I never thought I hadn't freshened up yet.

The telephone is made with the combination of the receiver and the microphone. That is, the most traditional way of using the telephone. Then remake the carbon microphone and install it in the phone. In order to differentiate the phone, Shang Wen ingeniously installed some small bells on the phone to prompt to answer the call.

Then simply modify the telephone line and power cord. Because the telegraph line was not recovered yesterday. Moreover, insulated wires are very scarce, and Shangwen can only pinch off the telegraph wire and replace it with a wire for telephones. At the same time, Shangwen also needs to make another telephone.

The phone made by Shangwen is except for some metal materials inside. The rest are all wood. And the second part. The same is true. Just when Shangwen was making the second telephone. Yingyu finished her washing and ate breakfast. Watching Shang Wen busying himself.

"Hey, idiot, let's have a meal." Ying Yu cried.

Shang Wen was busy working on the telephone, and didn't hear it at all.

"Hey. I'm eating." Yingyu shouted loudly.

"Oh. I see. I'll finish first." After that, I started busy again. Ying Yu pouted her little mouth to express her dissatisfaction. Had to eat alone.

It took two hours for Shang Wen to finish all his work.

"Okay. The call is complete." Shang Wen clapped his hands and said.

"This is the phone?" Ying Yu asked, leaning over.

"Yes. If you don't believe me, I went there to call you. Let you listen." Shang Wen said.

"That's great. I'll try too." Yingyu said.

"That's right. When you hear the ringtone. You pick up the phone. Remember, the end with the wire is underneath. The one without the wire is facing your ear. Just like this." Said Shangwen how to use the phone. Tell Yingyu.

"Oh. Oh." Yingyu nodded desperately to show that he understood.

"Then I'm going over there. I have to pick up the phone when I hear the ringtone." Shang Wen asked again.

"Oh, I see." Yingyu replied impatiently. Shang Wen had no choice but to rush to the other end to call Yingyu.

When making a call, Shangwen sends out an electric signal to call the other party with a hand-cranked micro-generator, and the other party starts the phone to form a call loop. So that two people can talk.

Shang Wen shook the micro generator to send out a signal. The telephone bell on Yingyu's side was ringing.

"Princess, this, this, this, the bell rang." The maid didn't know what to call it either. Then the bell rang.

"I know." Yingyu said impatiently. Maybe it was because I didn't sleep well last night. It made her feel a little bad today.

Yingyu didn't even look at the phone, but just picked up the phone as Shang Wen said, but she took it upside down. The end of the message was in her ear, and the receiver was beside her mouth.

Shang Wen saw that the other party was connected. He shouted loudly: "Hey, hey, hey. Talk. Hey." Shangwen shouted louder than ever. But the other party just has no voice.

"Why there is no sound. Damn idiot, dare to lie to me. I will kill him." Ying Yu said viciously.

"Princess, it seems that you have taken it upside down. The prime minister asked you to put the end with that thread underneath." The maid kindly prompted.

"Ah. That's it." Yingyu transferred the phone after speaking. But she just got it to her ear. I heard Shang Wen yelling "Hey hey."

Yingyu's ear was close to the receiver. I was shocked in pain. The anger came up all at once.

"Hey, what are you!" Yingyu retorted loudly.

"Oh. You finally picked up..." Shang Wen hadn't finished speaking yet. Ying Yu fought back again.

"Hey, let me feed you food. Beautiful thinking. You idiot." Yingyu shouted at Shang Wen, while the maid smiled. In Qin, even King Qin respected this gentleman very much. But the eldest princess was extremely disrespectful. And the two often fight and fight. It's also strange. The prime minister is rarely angry. Sometimes she took the initiative to make the princess happy.

"No, no. You listen to me." Shang Wen shouted loudly.

"What do you say. You say, you say." Yingyu said while holding the phone.

"Hey, it's a phone call to remind the other party to be there," Shang Wen said.

"Oh, wouldn't you use it to ask? A few more words can tire you." Yingyu said disdainfully.

"What's hey, it doesn't sound good at all. I don't know what you think...". Yingyu took the phone and chattered endlessly about this Shangwen. Shang Wen had no choice but to put down the phone. listen. Yingyu's voice was loud enough. Shang Wen motioned the person next to him to tell King Qin the news on the phone. Then quietly listened to the endless chattering voice of Yingyu on the phone. The first phone call in Qin's history. It was born out of scatter.
