Chapter 108 108. Journey to the Crystal Valley (9) Lisa (Part 2)

“Yes, this audio format file occupies a very small amount of storage, only a few megabytes for a song,” Lei Luo confirmed.

“But why have I never heard of audio files in this format?” Lisa asked suspiciously, blinking her big eyes.

“This is my first creation. It has smaller storage than the audio file format of CD players, and the sound quality is not bad.” Lei Luo considered the words, mp3 is a very common audio format in later generations, and this world has not yet appeared. .

[Congratulations,…seven in a row…, points +32000]

“Once your mp3 player comes out, what can you do with the CD player?” Lisa was a little surprised.

“There is basically no CD player. The world has always been the wave behind the Yangtze River and the wave ahead. The advancement of technology and the emergence of new products will inevitably eliminate some things. The big waves will wash away the sand,” Lei Luo explained patiently.

[Congratulations,…Eight in a row…, points +64000]

Lisa looked at Lei Luo’s eyes, there was a slight difference, and there was also a slight doubt. These fantastic ideas were actually made by the Chinese man in front of them? He was so young, he looked thin on the outside, but Lisa could see muscle and strength from his bare arm.

Then, Lei Luo began to introduce the core components-the main components of the mp3 chip: MCU, audio decoding DA conversion, DSP digital signal processor, audio amplifier, power management, USB, display interface, memory interface…

“These are the things you have to do, complete the mp3 chip design and PCB board circuit design, and I will find another manufacturer to do the appearance,” Lei Luo said.

“Can you show me your final appearance?” Lisa’s indifferent expression had already melted, turning into a curious baby’s appearance. The delicate and vivid face made Lei Luo’s eyes bright.

“Of course you can, wait for our company, I’ll show it to you,” Lei Luo said.

Lei Luo quickly interrupted the discussion between James and Professor Gullit, and brought Gullit and Lisa to the Jinggu Building where UST was located.

Lei Luo threw Gulite to Wu Ying to receive him and told him that the RF chip was designed with CMOS technology, and the research results, of course, belong to UST. Professor Gullit also has no opinion. Without funding from UST, there is no possibility of success in this matter.

“Don’t worry, I will pay the money separately, you just need to help me supervise the connection.” Seeing Wu Ying’s uncomfortable expression, Lei Luo of course knew the reason and quickly dispelled his worries. Sure enough, Wu Ying immediately became cloudy and fine.

Lei Luo took Lisa to his office, turned on the computer, and showed Lisa the mp3 appearance patents he applied for.

Lisa stared at the screen without blinking, excited.

“Wow, this look is nice and cool,” Lisa pointed to one of the exterior pictures and exclaimed to Lei Luo excitedly.

“Uh~”, Lei Luo also saw this appearance. This is the appearance design of the pan ipod in 2001. It seems that it can make the pan dead in spring, which makes sense! Anyone who looks at it is a bright feeling!

“Can I follow up to UST to complete the mp3 chip and PCB design?” Lisa was a little impatient. She wanted to see such a cool mp3 player. What is it like to listen to songs?

“Of course, you can,” Lei Luo said affirmatively.

Then, Lei Luo showed Lisa all mp3 related patents, including the invention of mp3 products, audio decoding, the appearance of mp3 products,…, and all the formats of the previous mp3 audio…

This is also for Lisa to better understand mp3, such as audio decoding patents, to clarify the specific decoding algorithm, which needs to be done in the mp3 chip.

When Lisa looked at the appearance patent before, she didn’t think there was anything, because it was just an appearance after all, and the technical content was not high. But when she was introduced by Lei Luo and fully understood all the mp3 patents, she was shocked. it goes without saying. Who is this? This completely blocks the possibility of others intervening in the product! Very awesome, and very ruthless!

As long as you want to enter the mp3 industry, you cannot circumvent these patent barriers and you have to pay Lei Luo. Lisa roughly calculated the global sales of CD players. It is estimated that mp3 will be at least a 100 billion-meter gold market! ! !

After making such a prediction, Lisa herself was taken aback by this conclusion! And the core components of this 100 billion market have to be developed by yourself, which is exciting to think about!

“Lei Dong, someone outside said it was your sister Lei Li.” At this moment, Ai Ping knocked on the door and came in and said to Lei Luo.

“Oh, let her in quickly”, Lei Luo said.

“She also brought a little girl,” Ai Ping said.

“Oh? It doesn’t matter, you can bring them here directly,” Lei Luo said happily. It should be Lei Li’s daughter and his little niece.

“Are you uncle?” A ten-year-old girl poked her head out of the door first. This little girl is obviously a mixed race, with some oriental characteristics, such as black and white eyes, but her golden hair is really typical. Western characteristics.

Behind the little girl, it was Lei Li who hadn’t seen her in many years. Lei Luo hasn’t seen her for several years, but she has not changed much.

“Sister, I’m sorry to let you run so far to see me and bring this little friend with you.” Lei Luo touched the little girl’s head, a little embarrassed!

“What’s the matter? It only takes a few hours to drive. Besides, isn’t it rare for you to come to the U.S.?” Lei Li said indifferently.

“You haven’t answered me yet, are you Ava’s uncle?” Seeing that Lei Luo didn’t answer her question, the little girl touched her head, a little unhappy.

“Of course, Ava, I am your uncle Lei Luo,” Lei Luo said with a smile.

Ava also saw Lisa in front of the computer and hurried over.

“Are you my aunt?” Ava tilted her head and looked at Lisa suspiciously.

“Aunt?” Lisa suddenly realized what her aunt meant, and she couldn’t help feeling a little embarrassed.

“Ava, this is Aunt Lisa”, Lei Luo hurried up to make a relief.

“Aunt Lisa is an aunt?” Ava was reluctant to forgive.

“No,” Lei Luo and Lisa said in unison.

“Then can I be friends with you?” When Ava saw Lisa, she naturally wanted to get close.

“Of course, but your uncle and I still have something to do.” Lisa patted Ava’s blushing face, also very happy.

“Okay, Ava, don’t make trouble. Let’s sit down on the sofa and let uncle work.” Lei Li pulled Ava over and sat down on the sofa.

Lei Luo and Lisa communicated for a while, and made an appointment for the next meeting. Lisa patted Ava on the head and walked out of the office.

Lei Luo and Lei Li hadn’t seen each other for a long time. They were so happy when they met each other in their hometown. Before they knew it, it was time for dinner. Lei Li has been in the U.S. for many years, and Jinggu has also come frequently. She is relatively familiar with the restaurants here, so she took Lei Luo to eat at Yushiyuan, which is a relatively authentic Sichuan restaurant, which has a similar taste to Chuzhou’s hometown cuisine. Today The two met in a foreign country and naturally wanted to taste the taste of their hometown.

Ava couldn’t eat spicy food, so she ordered a bowl of clear soup and made her hands. She held her mouth alone and watched the food on the table, but she could only count her hands one by one on the side, very unhappy, Lei Li and Lei Luo looked at each other and smiled, leaving her alone…
