NOVEL SIMPLE Chapter 72
Chapter 72 Battery (daily text)
“No, I bought a dozen tapes today and I ran out of money!”
“A dozen or so dishes? You don’t have much time!”
The normal price of the tape, the cheapest one is about ten yuan.
“Here! Here is it for you! You know it’s worth it if you listen to it!” Cheng Yongxing simply pulled the tape out of the player and handed it over.
“Why is this tape black! It doesn’t even have Chinese characters? What kind of tape is this?”
Lin Ting took the strange tape and inserted it into her player. As soon as the music rang, her mouth opened wide!
An unprecedented synthetic music sounded in her ears.
This kind of music is specially synthesized and strengthened artificially. The clear treble and the deep and powerful bass gave her a brand new feeling!
“Good! What’s the name of this song?”
“It’s written on the outside of the tape, I didn’t remember it!” There are several tunes on a tape, not everyone has an impression.
“You just said, gave me this tape?”
As she was talking while listening to music, Lin Ting’s voice became louder unconsciously.
“It’s fine for you! But keep your voice down!”
Cheng Yongxing pulled Lin Ting aside and took off one of her earphones. Two people wanted to enter the library and the other to go out, and the door was blocked.
“Okay, I’ll give you money!”
She would not accept such an expensive gift for no reason. A dozen yuan, almost a week of living expenses for students.
“The tape doesn’t have much money! You want to pay, give me two dollars!”
“Where can I go here?”
Lin Ting bought music tapes. It’s possible for a song in a foreign language to cost more than 20 yuan!
“Why don’t I give you twenty? I won’t have any more!”
“It’s not that expensive. If you don’t believe me, turn around and ask Yuan Shuai, we bought it together!”
Cheng Yongxing pushed back the few banknotes he had handed over.
————————
“Don’t believe it? Forget it, just take it and borrow it from me! I just got this tape and I haven’t heard it again!”
“Okay, that’s okay!” Lin Ting was also generous, and took the money back again.
“You bought more than a dozen discs? When will you bring it to everyone!”
After regaining her generous impression of her classmates, she climbed along the pole.
“Okay, I will bring a part of it for class tomorrow.”
“Take it all! Why take only a part?”
“The people in our dormitory also listen!”
“No, I have to pick it first!”
“Okay, okay! You pick first!” Cheng Yongxing never knew how to refuse a girl.
After the two made a few jokes, Cheng Yongxing looked at the player without the tape, and started to stun again.
“What are you thinking about? Isn’t it just picking a few tapes from you? I’m not picking them for myself! Hao Yunli and others will listen! I’m trying to win your favor!”
Lin Ting was slightly dissatisfied with the boys talking to herself and dared to distract herself. Of course, she is also used to it. Her appearance has always been unpleasant among girls. This is also one of the reasons why she developed a big-hearted character.
“Huh? Dissatisfaction? No dissatisfaction!”
“Then what do you think! I saw you in a daze just now!”
“I’m thinking about batteries! Batteries are too expensive!”
There are two main types of batteries on the market. One is a dry battery, which costs a few cents per unit, but has a short lifespan! A pair of batteries, listening to the tape, can only last about an hour. Alkaline batteries have a much longer lifespan, but the price is several times higher! A battery costs more than one yuan.
At this price, if he listens to music for two hours a day, his battery expenses will almost equal the food expenses!
Why do many students buy the imported RB thousand-yuan stand-alone player? It is these single-players, and some models use small lead-acid rechargeable batteries. One-time consumption saves the daily cost of batteries.
“I have two more batteries here! You can use them!”
Lin Ting is also an invisible little rich sister, occasionally listening to music or something, not particularly worried.
“But you gave me your tape, what are you going to listen to now?”
“No, I’m wondering if there is a way to do it once and for all!”
“Can the player use the battery?” Lin Ting’s eyes opened wider.
————————
Cheng Yongxing actually thought about a lot of things this time. Rechargeable batteries are the best choice. But he has no contact with chemistry at all.
He knew the name of the lithium battery! But how to refine, how to process, how to charge and discharge, what the battery fluid is, I don’t know!
It’s too strange to open up another battlefield in order to listen to music! If everything he is dissatisfied with is solved by opening the battlefield, then he doesn’t need to be busy with anything else!
“How is it possible! I’ve figured it out! Refit the flashlight and use the No. 1 battery to power the player!”
The price-performance ratio of AA battery is much higher than AA battery! In terms of volume, the capacity of one section is at least equal to 10 sections! The price is only about twice.
“Flashlight? Carrying a flashlight every day? Just to listen to music?”
This brain hole is a bit nondescript.
“It’s a flashlight, but there is no head. Only the battery compartment is reserved.” Cheng Yongxing opened his palm and gestured to the size, which was acceptable.
“Okay! That’s okay!” Lin Ting opened her mouth, and she didn’t think of a better way. In the university environment, Crouching Tiger, Hidden Dragon, she has given up the idea of comparing with these evildoers.
“However, you can make a set for me too!” The cost of the battery is also a big burden for Lin Ting. She is mainly used to learn English, which is just needed!
“Where can I find so many flashlights!”
“I’ll find one for you! Anything that doesn’t work well, right!” Flashlight, as a common item in this era, is still easy to find.
“Yes, in fact, I just want the battery compartment! It is big and stupid to make such a thing by myself!”
In the laboratory, all kinds of connectors and wires are available. Pull out a connector from the flashlight battery compartment, and you’re done.
“Well, you can make a look first! If it doesn’t look good, let’s find a way together!”
After several months of training, Lin Ting stopped being pester of these manual experiments.
————————
Mindful of those few tapes with damaged shells, Cheng Yongxing returned to the dormitory early. Inferior pirated tapes, after replacing the magnetic cores, are reminiscent of the new year.
This batch of tapes was warmly welcomed by the students! Especially those few heavy metal music style tapes. This kind of music, even in Hong Kong and Taiwan music, is not there.
The rock wave slowly began to rise. These musics are especially popular among adolescent college students.
The sound quality of tapped tapes is actually quite high. It is even higher than the batch of original tapes bought at Xinhua Bookstore. The treble is thorough and the bass is strong.
The only drawback is that these songs are not catchy. Not only couldn’t sing along, even Cheng Yongxing couldn’t fully recognize their lyrics.
These tapes are also suitable for playing background music.
Because the price of tape is too cheap. The students in several other dormitories also showed interest. But this kind of tape appeared once, and everyone went to search for it, and it has lost its trace.
