Huang Yuan is responsible for making all kinds of new gadgets. If he can't even use them, it must be Ying Feiyu who made them.
So Ying Zheng didn't even think about it and directly questioned Ying Feiyu.
"Nothing, just a loudspeaker device!"
Ying Feiyu looked at Huang Yuan, Ying Heng and others who were tinkering with the sound system on the other side of the lottery table, and couldn't help but laugh.
No wonder they were in a hurry and sweating profusely.
The lottery drawing time is coming soon, and they haven't figured out how to use this thing yet!
This set of speakers was delivered by Ying Feiyu who had just redeemed it from the system two hours ago. At the same time, he asked Huang Yuan and Ying Heng to debug and use it together!
Although I was taught how to use it, it was their first time contacting it and it was very unfamiliar to them. After plugging it in according to the method, it made the same sound, which frightened them and quickly disconnected the power supply. At this moment, they were gesticulating and studying it!
"Amplification equipment?"
Ying Zheng turned his head slightly and asked suspiciously.
"That's right...!"
Ying Feiyu smiled and nodded, then continued: "With so many people in the audience, no matter how loud you shout when the lottery is drawn, the people behind you won't be able to hear it! But with speakers and microphones, it's different. Amplify the sound dozens or even a hundred times! Even if the people on the stage speak normally, the people at the end can hear it clearly!"
"What?"
Ying Zheng was shocked after hearing this.
He has never seen such a magical machine!
Wang Wan and others also blinked and stared at Ying Feiyu, with curiosity written on their faces!
"There are buttons on the stereo that can control the volume! So, Huang Yuan and others were debugging just now...!"
Ying Feiyu smiled and walked towards the other side of the stage, "Father, please wait for a moment. I will go over there and help them!"
In order not to delay the lottery drawing time, he could only go there to debug it in person, and after the lottery draw was over, let them take it back and tinker with it slowly!
"Ouch! Brother Emperor, you're finally here! How do you use this big black box? We just turned on the power and there was an unusual noise, which startled us!"
"Yes! We also debugged according to the usage method? What went wrong?"
After seeing Ying Feiyu, Ying Heng and Huang Yuanxiang chased him and asked as if they had seen a savior.
"I'll do it!"
Ying Feiyu smiled and went over to play with it himself.
He was just afraid that these two guys wouldn't understand it. Ying Feiyu had tried his best to write down how to use it in more detail, but he didn't expect that he still couldn't!
It is estimated that the time is too short. If they are given some time to explore, they will definitely be able to figure it out!
"well!"
The two of them quickly stepped out of the way, allowing Ying Feiyu to make adjustments.
Ying Feiyu walked to the speaker, tinkered with it for just a moment, then picked up the microphone and said in a normal tone: "Good evening, everyone!"
However, the sound was amplified dozens of times through the stereo, ringing in everyone's ears like thunder!
"It's your husband! This is your husband's voice!"
After Zhang Xi heard it, he recognized it immediately.
"My husband's voice has become so loud? It's like shouting in our ears!"
"I feel like I'm floating in the air!"
Wang Wan and Yu Ji also spoke one after another and looked into the sky.
The common people were similar to them, and they all raised their heads and looked into the sky!
Looking for the thunderous sound, where did it come from?
If Huang Yuan hadn't reminded them just now, they would have thought that the gods were coming!
"Your Majesty, this black box can actually amplify the sound so much?"
Huang Yuan and Ying Heng were also amazed.
"Where are you going? I just turned the volume up to 30%! If I turn it all up, I'm afraid the eardrums of the people near the speaker will be blown out!"
Ying Feiyu smiled slightly contentedly.
"Brother Imperial, Brother Imperial, what is the principle behind this? Why can a small box make the sound so loud?"
This couldn't help but arouse Ying Heng's curiosity.
"This is not a small box, this... Ouch! The lottery drawing time is coming soon, I will explain it to you later!"
Someone was already moving the transparent glass box for the lottery to the stage. Only then did Ying Feiyu notice that the time for the lottery was almost over, so he swallowed back what he said in mid-sentence.
After handing the microphone to the steward of the lottery, Ying Feiyu walked in the direction of Ying Zheng, waiting for the lottery draw!
The lottery drawing method is almost the same as that of later generations. A completely transparent glass box was specially built, and inside it was a small ball with a number written on it, which was about the size of a table tennis ball.
There is a round hole in the glass box. When the wind blows into the glass box, the balls inside will start to fly. Whichever number jumps out of the hole first will be the winning number!
After the people saw the glass box, their hearts started to lift.
Whether they spend two pennies in vain or become rich overnight, it depends on today!
"Good evening everyone! Welcome everyone to come and watch Daqin's first lottery draw. I uphold a fair and impartial attitude and draw the lottery under everyone's supervision. I will announce the winning numbers on the spot. Please take your lottery tickets! All winners are welcome. Within two months, go to any lottery sales point anywhere in Daqin to redeem it...!"
The steward held a microphone and calmly walked to the stage and introduced the details to the people.
"It's so amazing. What kind of magic is it that can amplify the voices of people on the stage so much?"
"I don't know? I thought I couldn't hear anything from the back, and I bought a telescope at a high price! Now it seems that I won't use it at all!"
"Yes! With such a loud sound, I'm afraid even Xianyang City can hear the winning number clearly...?"
The people listened to the steward's speech, but the focus of the discussion was not on the lottery, but on what kind of equipment could amplify the sound so much, as if it were above their heads.
"Okay! I won't waste your precious time to win the prize! Now let's start the lottery!"
The steward stepped aside and made a gesture of invitation towards the glass box.
Then, the small balls inside began to fly continuously under the influence of the wind.
"Okay! Our red ball has started spinning!"
"when……"
After a while, a red ball successfully jumped out of the round hole reserved in the glass box, making a crisp sound.
"Haha! Our first ball has come out, and the number on it is..."
The steward picked up the red ball that jumped out, took a look at the number on it, and then deliberately played off the ball and made the last note long, making the people anxious.
Even the old guys all held lottery tickets in their hands and became nervous.
"This is just the first ball, so the ministers shouldn't be so excited, right?"
Seeing how nervous each one of them was that they couldn't breathe, Ying Feiyu couldn't hold it in anymore and joked with a smile.
