"Hey, operator sister, pick me up big brother." "I'm sorry, baby little lady, Xiao Langjun has already given an order, in the middle of the night, there is no emergency, and the phone is not allowed to be sent to him."

During this time, Yang Heng was annoyed, no matter what time the baby was interested, he would call the eldest brother to tell a story, and if he didn't finish three stories every time, it wouldn't be over, so Yang Heng directly gave the operator a death order, that is, after the hour, he was not allowed to answer the phone to the children, not only was it not allowed to pick up Yang Heng himself, but it was also not allowed to be done by others.

"Oh, okay, can I make a trick and don't give me the wire until the end of the day." "No, Xiao Langjun said, the baby and the little lady must be ringed at this time at the end of the year." Okay, even this, Yang Heng expected it, that is to say, every morning, the operator will ring the seven children at the same time, that is, to wake them up and make you want to play on the phone, that is at a price, and Yang Heng also knows that the baby will definitely bargain with the operator.

"Otherwise, sister operator, you can ring the bell, just ring one or two times, how about it, if you can, I will invite you to eat sugar gourd." This, even bribery, it can be seen that bribery, regardless of the size of the person, the baby knows that this ringing is unavoidable, then only shorten the time.

"In this way, Xiao Langjun does not limit the number of ringings, just vibrate twice, but the sugar gourd is exempt." "Then what about it, I will definitely invite my sister to eat sugar gourd."

If you want to talk about sugar gourd, it is also a kind that has only recently been invented. This is mainly due to the fact that Yang Heng's technical staff have recently researched white sugar. There's even rock candy. Therefore, the sugar dipped in the sugar gourd is available, even the glass of the sugar gourd is also there, so naturally this thing is easy to make, you must know that the hawthorn is a kind of fruit tree that Yang Heng found when he first arrived in the countryside, so this is all right, but because the price of sugar is still high. Yang Heng specially built a sugar gourd resale store in Dongshi, which is not an important thing, it can only be said to be a little money, so this sugar gourd shop belongs to the baby and others, which is the reason why the baby is very generous to give the operator the sugar gourd.

Since the phone was made, it has become a children's toy, and this phone is still relatively bulky, first of all, this thing is the same as the original Western phone in Yang Heng's previous life, a microphone in one place. A place for headsets when it's time to make a call. The headset is worn on the head, and the microphone is held in the hand, the only improvement is that the headset is the use of dual earphones, one ear buckle one, which can save people a hand, otherwise you have to hold the headset in one hand, take the microphone as soon as you put it away, and then take something is not possible.

At the baby's mentions, "Big brother, can you let our seven friends talk together, so that we can listen to the story together?" "Is this the original conference call model?

"Cheng, let the eldest brother study this." The child's proposal is very simple, but Yang Heng is not so simple to do, this is mainly because the diversion is too powerful, and it is easy to cause the voice to be too small, but fortunately, the headphones he made are all high-impedance headphones, in this way, it is relatively much simpler, for sound distortion, and even impedance mismatch, these are not things that Yang Heng cares about, once the prototype of this thing comes out, such a delicate thing, it is good to let the technical personnel solve it.

So, Yang Heng has another cousin who needs to be in charge of one thing, so who needs to be chosen, Yang Kun, that is, the fifth uncle's son Xiao Worm, similarly, he is interested in mathematics, and even interested in some small crafts, so call him over to see if he can learn this electronic technique.

"Big brother, what are you doing?" Sure enough, when other people saw this thing, it was curious, and when Yang Kun saw this thing, his eyes were hot, and he wanted to study what the principle of this thing was.

"Yang Kun, this is a telephone, you see this is all the principles, as well as the circuit diagram of these things, you such as this symbol is used to represent resistance, what is resistance, is the resistance to electricity, simply put, use the water pipe to make an analogy, such a thin water pipe, compared with such a thick water pipe, the water pipe passes through more water, by the way, per unit time, the thicker the water pipe passes, the more water passes, the thin means that there is resistance, and there is resistance to electricity passing through the line,...... Yang Heng naturally doesn't use professional terms to explain the matter of electricity, but some principled things still need to be explained, which needs to be done step by step, and now the primary purpose is to let Yang Kun have a general understanding, such as voltage, current, resistance, and the same analogy is made with thick and thin water pipes.

"Big brother, I understand a little, doesn't the current mean that the smaller the resistance, the greater the current?" "By the way, in the case of the same voltage, the smaller the resistance, the greater the current, naturally, there are still some differences between AC and DC, this needs you to understand slowly, and you have to slowly test it," but as a phone thing, this technique is one aspect, but the appearance is also an aspect, so at this time, Yang Heng not only transferred Yang Kun back, but also Niu Zi also asked Yang Heng to transfer back, he is responsible for the appearance design of the phone, Niu Zi, that is, Yang Yao, Yang Yao, It is also her own name, taken from the poem Tao Yao, the peach is young, scorching its bloom (lush peach tree shoots, blooming bright pink flowers). When Niuzi heard that this Xiao Xiao was a description of beauty, she gave herself a name Yang Yao.

Hearing that the girl named herself, the baby also followed the excitement and gave herself a name of Yang Zhuo, why, because she listened to Zhuo Zhuo's explanation is bright and beautiful, so she quickly took up this word, wishing herself to be able to look bright and beautiful, this female doll just cares about this beauty, if there are other explanations, they don't care.

The appearance of the telephone is not just a toy for the children, Yang Heng at this time is to pull the line to the mountains, the countryside Zhuangzi, and the princess's mansion, the princess is in the countryside Zhuangzi, daddy's Zhuangzi, and there is also one in each uncle's home, that is, a few are also installed in the academy, as long as there is a water source, Yang Heng can open 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 what to do about it, why, Yang Heng asked Changle and Yuzhang not to let the two of them say that the line to the countryside, as well as the line of the princess's mansion, was pulled simultaneously with the cable telegraph line, so it did not attract the attention of intelligence officers, and Yang Heng's home had completely restricted the arrival of Li Er's secret agent, so this matter was confidential.

At this time, the other ministers were playing with the telegraph, and chatting with each other on the telegram when there was nothing to do turned out to be a more fashionable action.

"Group hair, the weather is good today, who will have a treat?" These ministers, even know what is going on with this group send, Yang Li added another prefix, such as the prefix of the group send, once there is this prefix, it is sent to other ministers, and even Li Er can receive it.

"Mass mail, I think Lao Cheng should have a treat." "Mass hair, what are you doing, it's my grandson." "Qunfa, you are not grandson, who let you install the telegram in this minister's house first?" "Mass sending, I'm wronged, if you want to say that the first to install it was Tang Jian."

"Mass send, don't pull me up, pull me up again, I'll withdraw all your telegrams, it's better to let Lao Cheng treat you." "Mass send, support," "Group send, on the top floor." "This, are you texting, or are you building a building, why have you learned some of the things on the Internet in the later generations, who is here through time?

Because of this chat, Yang Li had no choice, so he opened a separate telegraph branch office, which was specifically responsible for these ministers, and the telegram as a state and county was another general office to be responsible, and Li Er's side directly pulled three special lines, one for chatting, one for government affairs, and one for confidentiality.
