rise in technology

Chapter 61 New Products

Everyone started to work step by step, and Zhang Wenkai also started his own work, which was to develop the next product.

Zhang Wenkai has given himself a clear position, that is, to be a developer, to turn all the advanced technology theories given by Xiaona into achievable technologies, and then hand them over to his own R&D department, so that the R&D department can turn him into products for their own profit.

At the beginning, Zhang Wenkai just wanted to make money, but now it is different. With his development, he has made a lot of money, so Zhang Wenkai's goal has gradually changed, and Zhang Wenkai's current goal is to let himself produce Advanced technology products fill every corner of people's lives, making technology benefit mankind.

This idea may be unrealistic, but Zhang Wenkai really wants to do this. Perhaps this is the idea that every descendant of China has had. "Achievement and benefiting the world" is printed in the bones of descendants of China.

Many people must have had this idea, but many people gave up in the end, because they couldn’t do it, so they had to give up. It doesn’t matter whether it’s good or bad, and there’s no need to worry about it. But Zhang Wenkai is different. He has the strength to do it, and he has the ability to do it. capital.

Since the launch of the wireless charger, although Zhang Wenkai has made a lot of money, Zhang Wenkai knows that this is not forever, but only temporary, because any product has its fatigue period, and it is normal to be weak.

With the decline in the popularity of wireless chargers, people's attention to him has decreased a lot. It can be seen from the fact that the orders received by Zhang Wenkai have decreased a lot, because Zhang Wenkai has not received large orders for a long time.

When the first-generation wireless charger was released, people might want to try it out of curiosity. When the second-generation built-in wireless charger was used to make a mobile phone, people might go back and try it because they were surprised by its functions. When the third-generation shared wireless charger is released, people may value their shared functions, share it!It is also a way to show off.

The occurrence of such a situation is also deliberately done by Zhang Wenkai, which is just a marketing method.

The reason for the decrease in orders is not because the price is too high. People will not spend more than 1000 yuan to add a wireless charging function just for a charging effect. Of course, local tyrants are exceptions.

This is also the result Zhang Wenkai wanted. If the original price of 1000 yuan was suddenly reduced to [-] yuan or even lower, what would be the effect?People still have to go crazy.

If such an advanced product is sold at the price of cabbage after it is produced, think about how other people will feel about this product. Although it is very advanced, it is inferior at the starting point.

The cost of Apple’s mobile phone is no more than 3000 US dollars. You can go and see how much it sells in China. The value of the product is obviously not in line with the price, but it is sought after by so many people. What is the reason? ?It’s not that Lao Qiao has done a good job in marketing strategy. If Little Apple sets the price at [-] yuan, everyone in China will definitely have a Little Apple, but why he didn’t do this is a question worth pondering.

No matter how good the product is, no matter how high the price is, it needs reasonable marketing methods to implement it, otherwise everything will be in vain.

And Zhang Wenkai's idea is somewhat the same as that of Little Apple, which is to raise the price first, to position people's thinking, make people think that this wireless charger is a high-end product, and plant seeds that feel very valuable in people's hearts, so that Zhang Wenkai's The plan worked.

Moreover, domestic mobile phones, which could only be used in the low-end market, have gradually begun to enter the high-end mobile phone market through the function of wireless chargers.

It can be seen from the foreign markets of Huawei and Meizu Company that the sales volume of the two companies’ products abroad has increased sharply. Although it cannot prove that they have entered the high-end market, many things have already been determined in terms of sales.

No matter what, there is always someone who tries first.

With the development and production of nanomaterials, it is completely possible to launch the fourth-generation wireless charger.

With graphene battery, ultra-long-distance wireless charging with high efficiency charging within 20 meters and normal charging within 30 meters.

Then through marketing means, the price of the fourth generation wireless charger is set at 1000 yuan, and then the price of the first three generations of wireless chargers is greatly reduced. By then, I will make a lot of money.

This is Zhang Wenkai's plan, a perfect plan, so perfect that Zhang Wenkai can laugh every day thinking about this plan, thinking why he is such a genius.

Now, Zhang Wenkai no longer accepts orders from other companies. After these orders are all completed, Zhang Wenkai plans to start implementing his own plan.

But before implementing the plan, I still have a very important thing to complete.

Zhang Wenkai took out Xiaona and put it on the table, and asked, "Xiaona, do you have the technology for wireless earphones?"

Yes, Zhang Wenkai intends to make a wireless headset, which is completely different from the traditional wireless headset.

Because whether it is a Bluetooth headset, an infrared headset, or a 2.4G headset, there are more or less shortcomings, and these shortcomings seriously affect the experience of wireless headsets.

Bluetooth headsets are the mainstream of wireless headsets now, but in Zhang Wenkai's view, the distance is still too short, and they are also susceptible to interference from the same frequency.

Although the infrared headset is very mature in technology, it can be said that this technology is not very suitable for the setting of wireless headsets.

Everyone is familiar with 2.4G earphones. 2.4G wireless technology is used in various aspects, and 2.4G earphones can reach a long distance, but the size is still a flaw.

It would be perfect if you could pinch the best of these wireless earbuds together.

"Sir, wireless transmission technology can not only transmit energy, but also transmit information." Zhang Wenkai didn't quite understand Xiaona's words, and looked at Xiaona puzzled.

"The current used by earphones is generally 10-80 mA, and the wireless transmission technology can realize the transmission. You only need to add a pair of smart conversion chips to convert the current signal into a sound signal." Xiaona explained in detail.

Zhang Wenkai was taken aback for a moment. He didn't expect that wireless transmission technology would have this function, which really surprised him.

Zhang Wenkai knew the general principle, but didn't know how to do it, so he asked Xiaona for the specific details.

Xiaona's projection disappeared, and several rays of light converged to form a schematic diagram of a pair of wireless headphones. Xiaona's voice sounded: "That's it, sir, his technology."

After listening to Xiaona's detailed explanation, Zhang Wenkai understood the principle.

To put it simply, a wireless receiver is installed in the headset, and then a sound conversion module is installed to realize the function of the wireless headset.

Take power from the mobile phone, and at the same time receive the power function to drive the earphone to run, and two functions of sound transmission.

The mobile phone needs to install a small chip that can emit current.

Although it was a bit troublesome, Zhang Wenkai still had great expectations.

However, Zhang Wenkai has doubts about the distance. If the distance is similar to that of a Bluetooth headset, then its meaning is basically meaningless.

"Xiaona, isn't it very close?" Zhang Wenkai asked suspiciously.

Xiaona's projection recovered, she held back her mouth, and said, "Every technology that Xiaona has produced is very advanced."

After a pause, Xiaona continued: "As for its effective distance, it can theoretically reach 60 meters. If it encounters obstacles, the distance will be reduced, but not too much."

60 meters?For this distance, Zhang Wenkai must also research it, you can imagine a picture.

A girl is wearing a dress at home. If she lies on the bed and listens to music with wired headphones, what if she wants to listen to music while cooking or doing housework? She can’t wear her mobile phone on her body. It’s so troublesome.

Some people will say, then use the stereo, that Zhang Wenkai can only tell you to use the stereo, headphones are not suitable for you.

Because listening to music with earphones and audio are completely different. If you want to listen to good sound quality, you must use earphones or headsets. The method of ear) is the same, can you hear the effect with the stereo?

Zhang Wenkai quickly took out some prepared materials, and said to Xiaona: "Old rules, let's start."

Xiaona naturally also knows what Zhang Wenkai meant when he said "old rules", which means teaching relevant knowledge principles while instructing.

"Sir, you need to solder a sound conversion module first." Xiaona pointed to Wen Kai and said, while the circuit diagram of the module was displayed on the projection.

Zhang Wenkai began to weld the sound conversion module according to the circuit diagram given by Xiaona.

After soldering the sound conversion module, connect it to the wireless receiver, and then connect the earphones to the sound conversion module.

Welding a current transmitter, which is somewhat like the transmitter of the wireless charger, but much smaller than the transmitter of the wireless charger.

Zhang Wenkai quickly completed the welding, and then came to everyone's favorite code typing relief.

Zhang Wenkai sorted the codes given by Xiaona, and typed it out on the computer while studying, and there was a crackling sound from the mechanical keyboard.

Then write the code program into the chip, and a wireless headset is completed in this way. Of course, Zhang Wenkai has not tested whether it is easy to use.

Zhang Wenkai took out his three-heart mobile phone. The paint on the edge of the mobile phone had already fallen off, but Zhang Wenkai did not change the mobile phone. It was not because he liked the three-star mobile phone, but because Zhang Wenkai did not have many requirements for the mobile phone. That's fine, Zhang Wenkai plans to get a Nokia 1110.

First, I plugged the current transmitter into the jack of the mobile phone, put on the wireless headphones, and played a song at random. The sound of the song came out of the headphones, but the sound effect was a bit poor, and it was accompanied by a slight current. Sound, so Zhang Wenkai told Xiaona about this situation.

Xiaona said without hesitation: "Due to material limitations, it is normal for this to happen."

Xiaona's words made Zhang Wenkai feel relieved, as long as it was not a technical problem, he put the phone in the room, and Zhang Wenkai walked out of the office, and then he wanted to test the distance.

Zhang Wenkai held the small circuit board in his hands and walked in the corridor of the company with headphones in his ears. He quickly attracted the attention of other employees in the company. Although he was a little curious about the behavior of the boss, no one said anything.

When Zhang Wenkai walked about [-] meters, the sound of the earphones became smaller and smaller. Zhang Wenkai knew that this was the limit of wireless earphones, so he returned to the laboratory.

I copied the circuit board design diagram given by Xiaona to the USB flash drive, then copied the code program to the USB flash drive, added the usage limit and non-copyable function, and left the laboratory.
