중국의 고정 유선 전화 기록
중국에서, 전신과 전화가 거의 동시에 등장했습니다.. 전신선이 건설된 후, 전화도 중국에 들어왔어. 많은 경우에, 전화선과 전신선이 공유되었습니다, 그리고 둘의 발전 궤적은 거의 평행했습니다.. 그들은 아니었다 전신이 중국에 소개된 후 더 발전된 전화기가 천천히 등장하기까지는 수년이 걸렸습니다.. 이번 호에 기재된 전화번호는 유선전화를 의미합니다., 로도 알려져 있습니다. “유선전화”, 휴대폰이 아닌 (휴대폰).
심천 EAST LINE은 전문 OEM 유선 전화 제조업체입니다..
1. 나전화의 발명
~ 안에 1861, 독일 교사가 최초의 전화를 발명했습니다, 짧은 거리에서 서로 통신하기 위해 음파의 원리를 사용했습니다., 하지만 실제 사용되지는 않았음.
전화기의 발명가에 대해서는 항상 논란이 있어 왔습니다.. 어떤 사람들은 안토니오 메우치라고 하더군요, 다른 사람은 벨이라고 했어, 또 다른 사람은 엘리샤 그레이라고 하더군요. 그런 것들이 많아요. The most famous one is Newton and Leibniz’s theory of micro-organisms. In the story of points, the main controversy is Meucci and Bell.
~ 안에 1849, the 41-year-old Meucci accidentally discovered that wires could transmit some sounds during an electroshock treatment. Then he made a simple sound transmission system. ~ 안에 1860, the 52-year-old Meucci demonstrated this system to the public and An introduction to the invention was published in an Italian-language newspaper in New York, when his rival Alexander Bell was only 13 years old. Because he was too poor to pay the patent maintenance fee, he sent the model and technical details to the Western Union Telegraph Company in the hope of commercial use, but nothing happened.
On February 14, 1876, Bell, who shared a laboratory with Meucci, applied for a telephone patent to the U.S. Patent Office, and the application was approved on March 3.
하지만, whether Bell independently invented the telephone, improved the sound transmission equipment, plagiarized Meucci, or used different principles, please stay calm. When science and technology develop to a certain level, 동일한 창조와 창의성은 여러 곳에서 발생합니다, 그것은 매우 흔한 일이다.
전신선은 원래 전화 신호를 전송하는 데 사용되었습니다., 그러나 그러한 선으로 인한 소음 간섭은 매우 컸습니다., 그래서 사람들은 통신 회선을 개선하는 것이 허용되지 않았습니다.. ~ 안에 1883, 두 번째 와이어를 루프로 사용하는 선이 나타났습니다., 전화 통신의 소음 간섭을 크게 줄였습니다..
2. The origin of the name “telephone”
~ 안에 1796, Hughes proposed a method of using a microphone to relay voice messages. Although this method was not very practical, he gave this method of communication a name: Telephone, which is still used today.
The Chinese word “telephone” is a Chinese word created by Japan. In fact, there are many Chinese names translated in Japan. In addition to telephone, the most famous one is the philosophical term “metaphysics”. Telephone is the free translation of the English word “telephone”. The Chinese transliterated this English word and translated it as “telephone”.
In the early 20th century, a group of foreign students from Shaoxing in Japan jointly wrote a reply to their hometown, which introduced the modernization situation in Japan in detail. Lu Xun was also listed among them. When the letter mentioned “telephone”, he specifically explained: “With electrical appliances, To convey words, the Chinese translated it as “telephone”, which is not as good as “telephone”. Gradually, it was called telephone. For a period of time, the two terms “telephone” 그리고 “telephone” were commonly used. Later, “telephone” “Wind” slowly disappears.
3． Chinese people came into contact with telephones for the first time
~ 안에 1876 (the second year of Guangxu), Ningbo customs official Li Gui was ordered to go to the United States to participate in the “World’s Fair” held in Philadelphia. He saw a telephone that could transmit messages, and wrote it in his book “A New Record of Traveling Around the World”. In the book, Li Gui is the first Chinese to see a telephone for which historical data are available.
In this book, he also made detailed records of the U.S. Postal Service and suggested that the Qing Dynasty also open a Chinese postal service. His insights were praised by Li Hongzhang, and he was subsequently ordered to draft the “Translation and Drafting of the Postal Service’s Rules for Sending Letters”, which included ten The specifications, features, rates, 다양한 유형의 통화 리디렉션. of several types of mail are specified in detail. When Kang Youwei was 22 years old, he read the newly published “New Records of Around the Earth”.
~ 안에 1877, the year after Bell invented the telephone, a Chinese was fortunate enough to use a telephone. This Chinese was named Guo Songtao, who was the first minister of the Qing Dynasty to Britain.
On October 16, 1877, Guo Songtao was invited to visit a power plant near London, England. During the visit, the owner specifically asked him to experience the telephone, which had recently been introduced to the United Kingdom from the United States. One end of the telephone was installed upstairs and the other end was installed downstairs. , Guo Songtao asked Zhang Deyi, the translator of the Chinese Embassy, to go downstairs to answer the call, while he made the call upstairs.
Guo: “Did you hear that?”
Zhang: “Yes.”
Guo: “Are you aware?”
Zhang: “Yes”
Guo: “Please count the numbers.”
Zhang: “One, two, three, four, five, six, seven”
This was the first time for Chinese people to use the telephone. Guo Songtao wrote down his experience of using the telephone in his diary: “There are many languages and there are many that cannot be understood, but this number is distinct.” He called it a “sound reporting machine”. Guo Songtao will What he saw along the way was recorded in his diary “Shi Xi Ji Cheng”, advocating that China should study and learn from the advanced technologies and systems of the West. After the book was sent to the Prime Minister’s Office, it was attacked and cursed by diehards. It was not made public until Guo Songtao’s death. issued.
As the professional OEM fixed telephone manufacturer, Shenzhen EAST LINE can supply lots of different kinds of corded landline telephones for home, office, hotel and public places.
3． Magnet Telephone
Bell’s phone is a magnet phone. The so-called magnet phone is also called a hand-crank phone or a crank phone. There is a crank on the left side of the phone. Before using the phone, you need to crank it to charge the battery. The general working principle is: When the speaker picks up the phone and speaks into the microphone, the vibration of the vocal cords forms sound waves, which act on the microphone, causing the carbon particles in the metal box of the microphone to become loose and tight – the resistance becomes large and small – circuit The current is strong and weak. , the voice current is transmitted along the line to the receiver of the other party’s phone. The magnetism of the electromagnet in the receiver becomes stronger and weaker – the magnetic force on the thin iron sheet becomes stronger and smaller – causing the thin iron sheet to vibrate and emit sounds that are connected to the speaker. Same sound.
