    "This phone call is much better than a telegram!"

    "You can have a direct real-time call, even the voice is the same, incredible, really incredible!"

    ¡°It is indeed a great invention!¡±

    Everyone couldn't help but marveled at this magical phone. There were more and more inventions in the Ming Dynasty. There were many great inventions and innovations in the Royal Academy of the Ming Dynasty, but this phone was still  It still makes everyone feel amazing.

    "Teacher Kuang, you have made a fortune. If you just sell this phone, you will get at least tens of thousands of taels of silver."

    "Yes, yes. It is said that the invention of the phonograph was sold for tens of thousands of taels of silver. In my opinion, the patent for this telephone can be sold for at least tens of thousands of taels of silver."

    ¡°Teacher Kuang, please remember to treat us to dinner this time.¡±

    "This is not the result of me alone, but the credit of the entire team."

    When Kuang Xiong heard this, he immediately smiled and said.

    Everyone¡¯s attention was focused on this new invention, but they didn¡¯t notice that Liu Jin had arrived at the scene. Even the principal, Xia Peiliang, was focused on the phone.

    "This phone is indeed very promising, but it still needs to be improved. These calls often need to be kept confidential, and it is best to be miniaturized."

    Xia Peiliang touched his mustache and said thoughtfully: "Its market prospects must be very good, but the initial investment must be huge."

    "Because it requires the establishment of special telephone lines, just like wires, the investment is not small and requires a lot of money."

    ¡°In addition, how to meet the needs of many phone calls is also a problem.¡±

    Xia Peiliang is indeed the president of Daming Royal Institute of Technology. He can see at a glance several problems that this phone will face if it is fully launched on the market.

    This made Liu Jin, who was watching on the sidelines, couldn't help but nod.

    First of all, the phone must be miniaturized, and secondly, it must pay attention to privacy. With such a speaker, the content can be heard by the surroundings. Obviously, it needs to be similar to the telephones of later generations. It must be miniaturized and put to the ear to listen.  , so that only the listener can hear the content.

    Secondly, the telephone line must be laid, and the telephone lines and wires are almost the same. Without lines, there is no way to make a call.

    The last problem is the exchange problem.

    In the early days of history, there were dedicated operators for telephone calls. For example, if someone wanted to call John Doe, he would first have to call the transfer center, and the operator would connect the call on his side to John Doe's place.  You can get through the phone call with John Doe.

    This is obviously also very troublesome. It is fine when the number of calls is not large. Once the number increases and becomes popular, the operator will be very busy and confused.

    So this is also a technical issue.

    "Principal, you have said a lot. This is indeed a problem that needs to be improved and faced."

    When Kuang Xiong heard this, he immediately frowned and started thinking.

    ¡°If these three problems cannot be solved, the phone patent may not be sold for much, but if these three problems can be solved, then the phone patent will be very valuable.¡±

    Xia Peiliang smiled and said.

    "The miniaturization and improvement of telephones are still very easy to achieve."

    "Assuming the route, it is obvious that a specialized trading firm is needed to do this, and there is no need to consider it."

    ¡°The only headache is the switching issue. If it¡¯s just a one-to-one call, I don¡¯t know how many lines have to be assumed, and a switching center is needed in the middle.¡±

    After Kuang Xiong thought carefully, he immediately came up with some solutions.

    "The switching center is a good idea, but if there are a lot of calls, it may not be possible to hand over the calls manually. In the end, it is necessary to invent a special switch to automatically switch without errors and faster."

    Wei Nanping, a professor of electromagnetics, thought for a while and said: "This switch must be an important invention. Who is interested in studying this thing together?"

    "I, Lao Wei, count me in!"

    "Count me in!"

    ¡°Count me in too.¡±

    As soon as Wei Nanping finished speaking, professors and teachers around him responded.

    This made Liu Jin on the side also laugh.He looked over quickly, and when he saw it was Liu Jin, Xia Peiliang and Wei Nanping, who knew Liu Jin, also quickly saluted respectfully: "Mr. Liu!"

    Only then did the others react and salute one after another. At the same time, the people around them also quickly made way for a way out.

    "Hello everyone, hello everyone."

    Liu Jin smiled and nodded with everyone, and then said to Kuang Xiong: "I paid 100,000 taels for your phone invention. What do you think?"

    "One hundred thousand taels of silver?"

    "Oh my God!"

    When everyone around heard this, they couldn't help but take a breath, and then their eyes turned red.

    One hundred thousand taels of silver!

    This is an astronomical figure for ordinary people. Even if it is placed in the bank, it will earn thousands of taels of interest for a year. This can almost buy half a house in the capital.

    If it is used for eating, drinking and having fun, the annual interest will be enough to lie down, eat and drink, and live an extremely comfortable life.

    In future generations, it will be equivalent to a small goal. If a small goal is given to ordinary people, they can definitely live a comfortable life.  (Remember the website address: www.hlnovel.com
