For a time, there was a "study fever" in Chang'an City, and every household hoped to secure a good future for their children.
Faced with such a grand occasion, those aristocratic families still insisted on their monopoly on knowledge and education.
They have the best educational resources, including knowledgeable teachers and rich teaching materials, which they are unwilling to share with ordinary people.
The little princess saw this scene and kept it in mind.
While recruiting craftsmen to open schools on a large scale, she also stepped up public relations for the mass production of radios.
After several weeks of unremitting efforts, Datang's first radio production line was finally completed.
The radios produced by this production line are also the famous crystal radios that occupy an important position in later generations.
This type of radio has a number of disadvantages.
For example, since the radio relies on minerals as detectors, its reception is affected by the quality of the minerals and debugging techniques.
The performance differences between different ores may lead to unstable radio reception, and users need to have certain debugging skills to obtain the best listening experience.
Secondly, the volume and sound quality of crystal radios are relatively limited.
Compared with the more advanced tube or transistor radios of later generations, the volume of crystal radios is smaller and the sound quality is not clear enough.
This limits its use as an entertainment device to a certain extent.
Again, it has high requirements for antennas and ground wires.
In order to obtain better reception, users need to carefully select and install antennas and ground wires, which increases the complexity and threshold of use.
Despite so many inconveniences, its greatest advantage made it the only choice for Datang's first batch of radios.
That is, the crystal radio does not require an external power supply.
This feature enables the radio to be used in any environment without being restricted by power supply, greatly improving its portability and practicality.
Whether in a remote village or in an uninhabited border, as long as people have a crystal radio in their hands, they can always learn about the developments of the outside world.
Secondly, the crystal radio has a wide reception range.
By adjusting the channel, people can listen to broadcasts from different frequency bands, including news, stories, music and other rich and colorful content.
This not only enriches people's daily lives, but also helps break down regional barriers and promote cultural exchanges and integration between different regions.
Furthermore, crystal radios are relatively cheap to manufacture.
It only consists of antenna, coil, capacitor, crystal detector and speaker.
The antenna is used to receive radio waves, the coil and capacitor are used to condition and amplify the signal, and the crystal detector is responsible for converting the radio waves into audio signals, which are finally played through the speaker.
This made this amazing device affordable for more ordinary people, further promoting the popularization and dissemination of information.
Although the crystal radio has some shortcomings, its advantages in the context of the Tang Dynasty undoubtedly made people place high expectations on it.
The emergence of this radio is not only a technological breakthrough, but also an important symbol of social progress.
After the crystal radio production line was completed, the little princess did not publicize it to everyone, but instead worked at full capacity to produce and stock up.
The first batch of radios produced were also sent to Mingda Bookstore and Mingda Colleges under construction in various places.
At the same time, the little princess also started to comprehensively expand and upgrade Mingda Radio Station, which has been running for nearly a month.
Under her careful planning, the radio station added several new channels to meet the diverse needs of different listener groups.
Among them, a special channel was opened to focus on broadcasting the national policies of the Tang Dynasty and real-time news.
Through this channel, people can keep abreast of the latest policies, major events and situations of the Tang Dynasty, so as to better grasp the pulse of the times and feel the development and changes of the Tang Dynasty.
In addition, in order to inherit and promote the splendid culture of the Tang Dynasty, the Little Princess also set up a channel for classic poetry and literary works.
In this channel, people can listen to the masterpieces of literati from all ages, feel the charm and artistic conception of poetry and songs, and further deepen their understanding and love of traditional culture.
Of course, the growth and education of children are also the focus of the little princess.
Therefore, she created a children's channel full of fun and knowledge for children.
This channel broadcasts a variety of content including fables and nursery rhymes, aiming to guide children to learn through entertainment and cultivate their imagination and creativity.
In addition, what the little princess cares most about is the role of radio stations in the field of education.
She added several channels to popularize basic educational knowledge and tell common sense of life, aiming to help people improve their cultural literacy while mastering more practical skills.
These channels cover a variety of fields including science, history, and art, providing listeners with a broad learning platform.
Aren’t those aristocratic families trying to monopolize knowledge so that children from ordinary families cannot access excellent educational resources?
The little princess thought, then Your Highness will use radio and radio stations to break this monopoly and give every child an equal opportunity to receive education.
So, while the crystal radio production line was running at full capacity, the little princess also began to plan the next step of the education popularization program.
She decided to rely on Mingda Radio to launch a series of colorful educational programs.
From basic arithmetic and literacy to more in-depth classics, history, and even practical farming techniques, handicraft skills, etc.
All teaching is free, everything is included.
After nearly a month of buying spree, almost every household in Chang'an City had added a few treasured books to their collection.
In addition, Mingda Bookstore adds books as scheduled every morning, so the book buying spree is no longer as intense as it was in the first one or two weeks.
But even so, every morning, a long queue of people waiting to buy books will still form in front of Mingda Bookstore.
When the door of the library slowly opened in the morning light, the common people and scholars who had been waiting outside the door poured in like a tide.
They may be looking for a book they have long admired, or buying books for their children, grandchildren, relatives or friends.
However, this morning, the moment they stepped into the library, a novel device unexpectedly caught their eyes.
That was the novel crystal radio, whose appearance excited everyone.
It has a simple and exquisite appearance. The black metal shell exudes a calm temperament, and the knobs and speakers are particularly eye-catching.
