It was already 11:30 noon when Chen Yao came out of the principal's office and walked into the school cafeteria.
Sniffling, the air is filled with the aroma of various food. I used to hate school food when I was in school, but now I actually miss it.
After leaving school for so long, I came back again. What I ate were food and feelings.
There was a long queue at the window, and Chen Yao didn't want to wait in line. He was just thinking about finding someone to prepare food for him.
Han Yuxin walked over with a smile and handed a lunch box into his hand: "Meals for you."
This girl who always has dimples at the corners of her mouth when she smiles is quite considerate. While she was getting rice, she also gave Chen Yao a portion.
Chen Yao was not polite to her, took the lunch box and found a seat to sit down casually.
And Han Yuxin followed him and sat next to him.
As a college beauty, she always tolerated the attention. She also brought food to another boy, which immediately attracted the attention of the boys around her.
"Who is that one wearing sunglasses? Why is Han Yuxin giving him food?"
"It is said that the school beauty has a secret crush on a male god, could it be him?"
"Holy crap, my goddess, has she fallen like this?"
Han Yuxin ignored the looks of others. She just admired her senior brother. As for what others thought, she didn't care.
Is there any difference between admiring someone and liking someone?
Interpreted literally, there is a difference.
However, if Chen Yao takes the initiative, Han Yuxin will not refuse.
At this moment, a boy wearing a white T-shirt came over with a lunch box and sat opposite Chen Yao.
His name is Cui Weixiong, a junior student at the School of Computer Science at Shenzhen University, in the same class as Han Yuxin.
He has been pursuing Han Yuxin for a long time. He has fallen in love with her since the first day she came to university, but he has never launched a pursuit offensive.
But today a boy suddenly appeared, and she seemed to be quite close to him, which made Cui Weixiong very unhappy.
"Yuxin, who is he?" Cui Weixiong asked with a smile on his face, pretending to be relaxed.
Han Yuxin changed her mind and said, "Classmates from this school."
Cui Weixiong guessed that they were related, but he didn't ask too many questions and ate the food in silence. His eyes glanced at Chen Yao from time to time, with some hostility in his eyes.
After the meal, Chen Yao got up and left the dining table and went to the faucet to wash himself.
"Let me wash it for you." Han Yuxin came over and reached out to take the lunch box in her hand.
She was so enthusiastic that Chen Yao did not refuse. Han Yuxin took the lunch box in her hand, put it under the faucet and rinsed it with dish soap.
People around looked over and asked, "What's wrong with the school beauty today? Is she so proactive?"
After washing, Han Yuxin went to the bathroom.
At this moment, Cui Weixiong appeared in front of him. He looked at Chen Yao with a bad expression: "What is your relationship with Yu Xin?"
Chen Yao really doesn¡¯t know what his relationship is with Han Yuxin. They have only met twice. They should be considered friends, right?
"What do you think?" Chen Yao finished speaking and walked around him.
Cui Weixiong warned: "You stay away from her. You can't chase a school beauty like Yu Xin. Otherwise"
Cui Weixiong took the wooden chopsticks in his hand and broke them with a snap: "You are responsible for the consequences."
Chen Yao glanced at it and walked out of the cafeteria. The sun was shining brightly outside, and the soft sunlight felt so comfortable on his face.
"Brother, come to my class." Regardless of whether Chen Yaotong agreed or not, Han Yuxin took the initiative to hold his hand and walked towards the class.
School of Computer Science, Class 2, Grade 3.
The proportion of girls studying computers is low, and beauties are even rarer. For school beauties like Han Yuxin, there are even more boys pursuing her.
Walking into the classroom, Chen Yao casually found a seat at the back and sat down, took out his mobile phone and clicked on it casually.
"Brother Weixiong, you grabbed it. Four people in my dormitory grabbed it together, but none of them got it."
"It's too difficult to grab. Many people want Legend speakers. They are out of stock online and offline. How did you get them?"
Chen Yao turned around and saw a group of boys gathered together, with a pair of legendary speakers placed among them.
"I just bought it from a scalper. The price is a bit high, 80,000."
Cui Weixiong gently touched the surface of the speaker with his fingers, turned on the speaker, and then selected a piano dance music, and the music immediately started playing.?.
The speaker instantly transformed into two human figures, a man and a woman holding hands and dancing.
The eyes of the students around me were bright.
"Bah!"
Cui Weixiong clapped his palms twice, and said with excitement in his tone: "Now, I will demonstrate this speaker to everyone, and give you a review by the way. There are some functions that Director Chen did not have time to finish at the press conference."
He is an audio enthusiast and is very good at speaker equipment. The students all want to hear his reviews.
The whole class sat down. Cui Weixiong stood in front of the podium holding a pair of speakers and put down the speakers.
Then, he played the song "Red Bean".
He smiled and said: ¡°Legend speakers also have a very cool function, which can control the propagation range of sound.
What are the benefits of controlling the sound range in this way?
It is like a liquid, controlled to play within a range, and will not exceed this range, nor will it affect people outside this range.
For example, if you are listening to music at home, but you don¡¯t want the sound from your speakers to spread outside the room, be heard by others, and interfere with others, you can turn on the range control function. "
The students were surprised that sound can also control the transmission range. How is it possible?
Cui Weixiong turned on the speaker, played a song "Beautiful Flowers and Butterflies", and then set its transmission range in the speaker, right in the classroom.
"He Daqiang, can you hear the sound outside the classroom?" Cui Weixiong looked at the boy wearing a red T-shirt.
Immediately, He Daqiang stood up and walked outside the classroom.
A magical feeling appears!
The singing I heard in class was obviously very loud, at least 60 decibels
But as soon as I walked out of the classroom, only 5 centimeters, 5 centimeters away, the sound disappeared immediately.
He turned around and stood at the door of the classroom, stuck his head into the classroom, and the singing came back immediately.
He was surprised: ¡°You can really control the range of your voice, it¡¯s incredible!¡±
Cui Weixiong set it up again and controlled the sound propagation range to 1 meter. ¡°Now the singing can only be heard within one meter of the speaker.¡±
He Daqiang immediately approached the speaker. Sure enough, within a range of 1 meter, the sound was so loud.
But if you step 5cm away, the sound disappears completely.
"Holy crap, what kind of weird technology is this?"
Traditional speakers can only achieve sound attenuation as the distance increases.
But the legendary speakers are directly divided into two worlds by just 5 centimeters.
Doesn¡¯t sound travel through the air? Legendary speakers can actually block sound out of thin air?
God, this is a barrier out of thin air!
The students are very curious, how is it done? (Remember the website address: www.hlnovel.com - Didn't finish reading? Add this book to your favoritesI'm a member and bookmarked this chapterCopy the address of this book and recommend it to your friends for pointsChapter error? Click here to report
