"Hey, sister of the operator, please pick me up with my elder brother." "I'm sorry, baby lady, the little husband has already given the order. In the middle of the night, there is no urgent matter, so I am not allowed to answer the phone to him."

During this period, Yang Heng was so annoyed. At night, when the baby came, he would call the elder brother to tell stories. Moreover, if he didn't finish three stories every time, it would not be over. Therefore, Yang Heng directly issued a death order to the operator, and after the hour of Hai, he was not allowed to answer the phone to the children. Not only was he not allowed to answer where Yang Heng himself, but he was not even allowed to take other people.

"Oh, okay, then can I make a trick? Even if I don't have to take the line before the hour of Mao, I'm not allowed to take the line." "No, the little husband said that the baby must ring the baby at the end of Yin and early Mao." OK, even Yang Heng had expected this, that is, every morning, the operator would ring the seven children at the same time, that is, to wake them up and make you want to play the phone, which is a price, and Yang Heng also knew that the baby would definitely bargain the operator.

"Or as this happens, the operator sister, you can ring the ring, just ring it once or twice, how about it? If possible, I will treat you to candied haws." This is even bribery, which shows that bribery is no matter how big or small the baby knows that this ringing is inevitable, so he can only shorten the time.

"This way, the little husband has no limit on the number of ringing times, so he can only shake it twice, but the candied haws will be spared." "How can it be? I will definitely invite my sister to eat candied haws."

If you talk about candied haws, it is also a kind of invented recently. This is mainly because Yang Heng's technicians have recently developed sugar and even rock sugar. Therefore, there are sugar dipped in candied haws, and even glass to throw candied haws. Naturally, this thing is easy to make. You know, hawthorn is a kind of fruit wood that Yang Heng discovered when he first arrived in the countryside, so it was all in one. However, because the price of sugar is still high, Yang Heng specially built a candied haws resale store in Dongcheng City. This is not an important thing. It can only be said to be a little money, so this candied haws shop belongs to babies and others. This is why babies are generous in giving candied haws to operators.

Since the phone was made, it has become a toy for children. The phone is still relatively bulky now. First of all, this thing is the same as the first phone in Yang Heng's previous life. The microphone is one place, the headphones are one place, and the headphones are worn on the head, while the microphone is held in the hand. The only improvement is that the headphones are made of double headphones. One ear is buttoned on one, which saves people a hand, otherwise they have to hold the headphones in one hand, hold the microphone, and then hold the thing.

In the baby's mention, "Brother, can you let the seven of us friends talk together so that we can listen to the story together?" Is this the original conference call mode?

"Success, let the elder brother study this." The child's proposal is very simple, but Yang Heng is not that simple. This is mainly because the diversion is too powerful, which can easily lead to too little voice. Fortunately, the headphones he made are all high-impedance headphones. In this case, it is relatively simple. For sound distortion and even impedance mismatch, these are not what Yang Heng is concerned about. Once the prototype of this thing comes out, so fine things need to be solved by technicians.

So, Yang Heng had another cousin who needed to take charge of something, so who should he choose? Yang Kun, the son of Uncle Wu, Xiao Chong. Similarly, he was interested in mathematics and even some small craftsmanship, so he called him to see if he could learn this electronic technology.

"Brother, what are you doing?" Sure enough, the others were curious when they saw this thing, and Yang Kun saw this thing because his eyes were hot. He wanted to study the principle of this thing. When Yang Heng saw it, he said, "After that, he left it to him."

"Yang Kun, this is a phone. You see, this is all the principles, and the circuit diagram of these things. If this symbol is used to represent resistance, what is the resistance? It is the resistance to electricity. Simply put, use water pipes to make a metaphor. Compared with such a thin water pipe, the more water pipe passes through such a thick water pipe. By the way, in a unit time, the thicker the water pipe passes through the more water. The thin one means there is resistance. There is also resistance to the passing of electricity in the electric circuit...." Yang Heng naturally would not use professional terms to explain electricity, but some principled things still need to be explained, which needs to be gradually improved. The primary purpose now is to give Yang Kun a general understanding, such as voltage, current, resistance, and the same metaphor is used to compare thick and thin water pipes.

"Brother, I understand a little. Is the current that means the smaller the resistance, the greater the current?" "By the way, with the same voltage, the smaller the resistance, the greater the current. Naturally, there are still some differences in AC and DC. This requires you to slowly understand it, and you have to slowly conduct experiments." However, as a telephone, this technology is one aspect, but the appearance is also one aspect, so at this time, Yang Heng not only adjusted Yang Kun back, but also Niuzi also asked Yang Heng back. He was responsible for the appearance design of the phone. Niuzi, that is, Yang Yao and Yang Yao, was also named by her. It was taken from Taoyao, Taozhiyao, Taozhiyao, and the brightness of the flower (the tender branches of lush peach trees are budding with bright pink flowers). When Niuzi heard that Yaoyao was a beautiful appearance, she gave herself the name Yang Yao.

When she heard Niuzi name her, the baby followed her and gave herself the name Yang Zhuo. Why? Because she heard Zhuo Zhuo’s explanation that she was very beautiful, she quickly took over the word, wishing her to be very beautiful. This girl cares about this beauty. If there are other explanations, they will not care about it.

The appearance of the phone was not just toys for the children. Yang Heng pulled the line to the mountains, the countryside villages, and the princess's mansion. The princess was in the countryside villages and the father's farms. Every uncle also had one at his home, and even several were installed in the academy. As long as there was a water source, Yang Heng could turn on the phone. Why? This is because of the convenience of power supply.

Although Yang Heng made such a big move, Li Er didn't know about this. Why? Yang Heng asked Changle and Yu Zhang not to let them say that they were just to pull the route to the countryside and the Princess's Mansion, which were all drawn simultaneously with the cable telegraph route, so it did not attract the attention of intelligence personnel. Yang Heng's home had completely restricted the arrival of Li Er's spy, so this matter was kept confidential.

At this time, other ministers were playing with telegrams. They chatted with each other on the telegram if they had something to do, which turned out to be a relatively fashionable action.

"Multi-send, the weather is good today, who will treat you?" These ministers even knew about this group of senders. Yang Li added another word header, such as the word header of the group. Once this word header is available, it will be a group sender to other ministers, and even Li Er can receive it.

"Mass, I think Lao Cheng should treat him." "Mass, why, it's my grandson." "Mass, you are not grandson, who asked you to install the telegram first in this minister's family?" "Mass, I'm wronged. If you want to say that the first install was Tang Jian, okay?"

"Mass sending, don't pull me up, and I'll remove all your telegrams. It's better to let Lao Cheng treat you." "Mass sending, support," "Mass sending, on the top floor." Are you sending text messages or building a building? Why are you learning some of the Internet things in later generations? Who has traveled through time?
