Chapter 251 (2/2)

”Well,” Donne smiled inexplicably, ”have you ever heard of the square trumpet?”

”... what's that?”

”You'll know soon.”

Loudspeaker... Well, sorry, let's talk about the speaker gracefully.

The gnomes have already developed such things as speakers, Gnome expansion... Gnome speakers have been used in many places by kroto and they have used them for short-distance communication and information transmission. In fact, with a little development, they can expand the wired telephone.

But Donne is more willing to use magic to change the speaker, because it is a little difficult for a layman to make a phone by scientific and technological means

However, if the problems of accurate call, ”signal” attenuation and transfer are solved, he can successfully make a magic modified mobile phone.

Of course, the magic technology of ultra long-distance communication already exists, but the use cost is too high to be popularized to the civilian level. Only by using some small spells to realize magic to change mobile phones can it be popularized successfully.

It is also very simple to use magic modification to realize the effect of the speaker. The sound is generated by the vibration of the medium. The speaker increases the sound intensity to increase the propagation distance, but what about using magic modification? With the help of invisible magic and tangible elements, the sound can be transmitted to a very far place without changing the sound intensity, and the other party can hear it as clearly as it sounds in his ear.

So let's expand our thinking. Since the omnipresent magic and elements in the world can replicate the vibration of sound to achieve long-distance non-directional propagation, what about the directional propagation between specified matching objects? How to enhance and transfer the attenuated signal?

If the above two points can be realized, the birth of magic modified mobile phone is just around the corner!

In fact, the enhancement and transfer of attenuated signals are easy to solve. We only need to arrange the enhancement nodes to unconditionally strengthen the received magic signals. The difficulty is to specify the directional propagation between matching objects - which is equivalent to mobile phone dialing. If each dialing is an undirected wide area call, when there are many users, The interference of magic to the whole world is extremely serious and the consequences are unimaginable.

Of course, what Donne wants to get out now is just magic expansion... Magic speaker.

A speaker network is laid in Ellington, and then Datang radio station is established to broadcast programs regularly to attract listeners. Then any emergency news can be smoothly transmitted to Ellington residents at the first time.

After lunch, many walking residents suddenly found a small spire at the top of the Lord's house.

Just when those people were full of doubts, they suddenly heard the clear voice of the Lord in their ears.

”... yes, that's it. Open it there and speak to it. The sound can spread out - what? You've opened it? Why didn't you say it earlier!”

Then there was a messy sound. After a burst of chicken flying and dog jumping, the sound became a very sweet female voice, which was obviously full of excitement and excitement.

”Hello, everyone! You can know the world without leaving home. This is Datang radio. Repeat, this is Datang radio! For the first trial, please don't be nervous and don't panic. I'm Marlene, a special announcer of Datang radio station. Lord, can you hear my voice? Oh, oh, OK!”

”Eh? Isn't that Miss Marlene's voice?”

An aunt was surprised: ”isn't she a maid in the Lord's house? How did she become a special announcer?”

”What is this Datang radio station? Is it a new thing made by the Lord?”

”Well, this afternoon news broadcast, the weather is sunny today, the current temperature is 35 degrees, no cloud, no rain, the light is strong, and the air is slightly dry. Female friends, don't forget to buy a mint pure dew and pat it to replenish water.”

”Ah! Miss Marin, I forgot if I didn't say it. My skin is almost dry!”

”Go back and pat Mint pure dew to replenish water!”

”Today's noon news includes the following contents: the situation in the yarinks has changed, and the price of magic crystal has collapsed; the Kadir family is eager to get out of the pit, but the auction venue is cold; the Lord threw tens of thousands of gold and the crystal mine has successfully changed its owner; the Datang chamber of Commerce has turned the tide, and the former enemies have become today's saviors; to ask whose lover has become the fruit, we should also look at the imperial capital romantic bolette; the residents are busy with the construction of one heart, and people are busy My hands are not enough and my heart is flustered. The Lord has a clever plan to help me with elemental creatures... ”

”The following is the main content of the news. In recent days, Alex...”

Hearing what was told on the radio was actually what happened in alinks thousands of miles away. These people were boiling. For the vast majority of them, they may not leave Ellington for a lifetime. They can learn about the imperial capital without leaving home. They can't appear in their dreams!

Many people who heard the radio could not help but slow down, relax their nerves and began to listen to the radio news.

When they heard the price collapse of magic crystal, they were amazed. When they heard that Tang Enhao threw tens of thousands of gold to buy the mine, they couldn't help sweating for Tang en. When they heard that Tang en successfully rescued the market with Datang daily and pulled the price back, they couldn't help cheering for the leader!

Then, when they heard that the LORD would summon elemental creatures to help build Ellington, they were too excited to control their emotions.

Whose Lord can have such means and courage?

No,

Only Ellington!
