"So you all understand, don't you, now?" Nata asked a question interrupting the shock of the people in the room.
"I still don't understand even though I've seen it" Couran said honestly.
"If it wasn't magic, don't know what it was?" Jean looked slow.
"Science. Science" said Aksa.
"And how does that electricity turn back into sound?" It seemed that Couran was still not finished with his curiosity.
"Behind this funnel was an empty space lined with animal skins. Behind the skin is a needle attached to a magnet in a coil." This time Nata answered trying to explain.
"So when the copper cable is electrified, a magnetic field will be created. And when there is a difference in closure, the magnet in the middle will move. And if it follows the pattern of the previous electric current, then the magnetic motion pattern will be the same as the pattern of sound waves coming from the microphone.
"And the animal skin that vibrates because of the movement of the needle was valid as a creator of air pressure, while the mouthpiece serves as a loudspeaker," closed Nata later.
It looked as though Couran was starting to faintly nod in understanding. Contrast that with most people who have absolutely no understanding of what Nata and Aksa have been talking about.
"Basically this tool mimics the workings of the vocal cords and eardrums." Nata added.
"Oh, and before you ask me what the function of the Audion tube is, I'll tell you first," sela Aksa pointed towards the glass tube like a light bulb on the side of the wooden box.
"So this big light bulb is called the Audion Tube?" ask Couran while observing more closely the glass tube.
"really. So this old Triode serves as a current amplifier. Its existence is very important for equipment related to sound and electrical signals," explained Aksa who no longer interests others. Because it's too hard to understand.
"I saw nothing but a metal slab surrounding a metal rope that looked like it was inside an incandescent light bulb. No Cog Wheels, no coils, so how does this thing work? Is the metal plate a magnet?" Couran still looks curious.
It seemed that the others were a little annoyed to see Couran still asking questions that they obviously would not be able to understand.
"Yes, curiosity is the breath of science. You are truly a true scientist, Mr. Couran," Aksa praised before beginning his explanation again. "So this tube is vacuum, because otherwise, the filament would be instantly damaged when it burns oxygen once heated. Yes, just FYI," he added later.
"alright. So this tube still uses a similar way of working with incandescent light bulbs in general. Thermionic Emissions. The process of removing electrons from a material by heating it. It's just that for an incandescent ball the goal is to create a photon because it only has one element in the tube. While in this Audion tube there are three elements. Where the anode serves to attract electrons released Cathode, which means directing the current back and forth. Alias changes the current from AC to DC. And the third element, the Control Grid, I often call it the electron filter, serves as a regulator of the large and fast rate of electrons to the Anode. Well, from this Control Grid, we'll... "
"Sorry to interrupt" said Lucia like a wish to those who could not bear the long explanation of Aksa. "I think you can continue your discussion on the matter together after this meeting is over."
"Oh, fine, then." Aksa answered hesitantly with a slightly disappointed face as Lucia cut through the explanation.
"I'm sorry to have hindered the course of this meeting, Her Majesty the Queen," Couran said immediately, bowing respectfully to Lucia.
"It's no problem, Mr. Couran. So what's the point of this tube actually?" ask the girl later. "Simplistically," he again warned.
"So this tool is an important key if we want to communicate as far apart as before, but without being connected to the cable." Nata added, which immediately attracted the interest of Lucia and the military elite who had heard Nata talk about how to communicate with the group of soldiers that would be made later.
"So you mean we can communicate remotely without a password and light, and also without fear of leaking it, with this tool?" Caspian asked with a face full of hope.
"It may not be too far, either." Nata.
"We also still have to work on the transmitter section first before it can really be implemented" said Aksa interjected. "And not to mention talking about what kind of Sutet we will build to accommodate it later" he added later.
And the hum of a cheerful voice began to be heard from the people around the two young men.
"This knowledge will change many sectors of the kingdom very drastically" said Cornelius, who had just stayed behind Jean.
"We can make an announcement, a warning, or just greet the entire kingdom with almost no harm. Although from the east coast to the west coast, or from the North City to the South City. Faster than the Steam Train," said Aksa who was lured along eagerly give ideas in the use of their new technology.
"It's really amazing. This tool will change the civilization of this land."
"Yes, it's because we both have decided not to hold back. Therefore from now on and in the future, you will often see things like this from us," said Nata responded.
"really. Now we're going All Out!" timpal Aksa raised his fist into the air.
"With dozens of awesome pieces of equipment before, you said you were holding back all this time?" matyas asked with a cynical smile.
"Did you know what else you're gonna get out of those heads?" Couran was only able to sigh deeply at the 'will not hold back' words from the two young men earlier.
"So with the means of communication, can we receive a warning from the guard post at each gate immediately?" This time it was Lucia who spoke after a while before trying to digest and understand the information.
"We can also make it as a medium of entertainment. Request Music for example." timpal Aksa gave some other ideas to Lucia. "Oh! Wait a minute, we're not ready for that. Yeah, I think just communicating is enough for now," he added later.
"But that means we have to install the cable network to the entire region first?" ask Lucia to make sure.
"For a while we can use the copper cable of the electrical network that has been installed" answered Nata to provide a solution.
"remarkable. Then immediately install, at least at the guard post at each gate of the region, once the tools are completed," said Lucia gave the order.
"Okay, Her Majesty the Queen," replied several of the leaders of the region almost simultaneously.
"And talk about things like this." Lucia took over the conversation. "You guys haven't discussed this with me, but I heard the craftsmen are talking about the Airship, is that true?" tanyanya stared at Aksa and Nata in turn. "Are you going to build a ship that can float in the air like the ones in those pictures in the Laptop?"
Everyone seemed to be silently anticipating the answers of the two young men.
"really. And that's why I made the attack plan." Nata answered without burden.
"It's hard to believe" said Lucia. The face of the girl looks complicated. Although there was relief on his face, there was a hint of fear in his eyes.
Nata realized this. But he did not intend to ask. He will find a special time to really talk about what Lucia has in mind right now.
"So therefore we will attack the territory behind the opposing line of defense? Because we don't even need to cross that line of defense at all." Caspian was amazed at the analysis and conclusions he made himself.
"This will turn the war's course." Helen voiced her thoughts.
"It's not just war. This will change the way the people of this Elder Land live in the future." Val adds.
