Chapter 324: Dark Heart

I hope I can come up with something at the explanation meeting at the end of the month. It must be useful.

Where does Hongchuan Electric’s dry goods come from? Of course it’s not SIC.

"Senior Brother Nakajima, are you sure there is no problem?"

Hong Chuanfeng carefully held the machine in her lap with a suspicious expression.

"Ahem~" Heitaro Nakajima said a little uncertainly, "It should be fine. If you can handle a press conference, it's probably not bad."

Should it? After Hongchuan Feng heard what he said, his face became more and more uncertain.

Can you ask for something that will be displayed at the public prospectus? Don't make any mistakes.

Hong Chuanfeng decided to actually test the performance of that prototype machine, so he held the machine with one leg and pressed the switch button with the other leg.

When you swipe, a line of crescent red "KITA" logo pops up on the bright black LCD screen. The bright red display effect makes the black machine look mysterious and technological.

After waiting patiently for two seconds, as the interface was loaded, bursts of music soon came from the speakers placed on the table.

Well, not bad, the sound is bright and clear, much better than the tape machine.

Especially the clean sound, with no background noise at all.

Compared with the rustling sound in the background of tape and vinyl, it is simply noise.

Sure enough, digital music has so many advantages over analog music that it will become the mainstream of audio technology development in the future.

That's right, what Hongchuan Feng is holding in his legs at the moment is Hongchuan Electric's portable CD player.

After almost a year of hard work, the previous large and bulky desktop CD player has been successfully slimmed down.

The size is similar to the size defined by Hongchuan Maple last year, slightly larger than a CD case, and the thickness is about the height of 4 CDs stacked.

To be honest, from the perspective of future generations, it is not too thin and frivolous, but too thick.

But at that time, miniaturizing a desktop CD player to that extent was already considered a black technology.

The reason why Buluo Hongchuan Electrical Appliances can miniaturize portable CD players to such an extent is actually suspected of "cheating".

Why do you say that? Just look at the other battery box Hongchuan Feng holds in his legs.

Can this portable CD player be powered by an external battery box alone?

The working mode of a CD drive is completely different from that of a tape drive. It requires a laser head to irradiate light waves to read the information on the disc, and it requires a high-speed rotation of the motor to drive the disc to rotate.

In addition, the DAC chip outside the machine simultaneously decodes the information and outputs the sound as sound waves through the power amplifier system.

There is no doubt that its power consumption and rated current are higher than those of a tape drive, and ordinary AA dry batteries cannot carry it.

If the power supply problem is solved, Heitaro Nakajima and others can use AA batteries with larger capacity.

As we all know, the No. 2 battery is too thick compared to the No. 5 battery. It is a little thinner than the No. 1 battery in the leg flashlight they used when they were children.

The Hongchuan Electric portable CD player requires at least 4 AA batteries to work properly, so that the machine can maintain sufficient battery life.

If you want to integrate four thick AA batteries into the outside of a portable CD player, it is too difficult and impossible to do.

If you insist on doing this, then the current portable CD player will be very big.

Hong Chuanfeng looked at the thick CD player in his lap and shook his head. If that were not the case, the so-called portable would be nothing more than a name.

So the best option is to separate the mechanical and electrical components and make a separate external battery box for the CD player, which will look much smaller.

Although it has an additional battery box like a power bank, it is still portable.

Look, Hongchuan Feng took two steps with it, and there was no problem at all.

And considering the usage scenarios, Hongchuan Electric also reserved a 110V mains power interface for the portable CD player when designing it.

In other words, it can be used when plugged into the power supply at home. If you take it out, you can rely on the battery in the battery box.

Although it seems a bit sloppy, it is not much more advanced than Sony's desktop computers.

Hong Chuanfeng bumped the CD player in her lap with satisfaction. Tsk, it looks pretty cool.

"Hey~" Suddenly the speaker on the table stopped and there was no more music.

"Uh." Heitaro Nakajima, who was next to him, looked embarrassed, while Hiroshi Ogawa, who was further behind, turned red.

Hongchuan Feng was stunned for a while, and then quietly put the CD player in his lap flat, and the beautiful music sounded again.

"Junior brother, the current model needs to be improved, it needs to be improved~" Nakajima Heitaro's face turned red with embarrassment.

After all, today's CD players are too fragile and have almost no shock resistance. If they move even a little bit, they might stop working.

Hong Chuanfeng shook his head, "There is a little time to see if we can make any further improvements. At least we must persist until the end of the briefing session."

"Hey, they have been making continuous improvements." Heitaro Nakajima also expressed his sorrow.

Because according to expectations, Hongchuan Electric's portable CD player was originally planned to be launched in October or November.

But if we had to rush for that press conference, the time would be abruptly advanced by three or four months.

Time is already tight, and if it is greatly compressed like this, some small bugs are inevitable.

In fact, Hongchuan Maple does not insist on releasing new models in July.

Does he want to take out a finished machine to show to the outside world first? As for the actual launch, he will not launch it on the market in October or November as originally planned.

However, the production line for CD players has not yet been built. If you want to get a finished machine, you can rely on the laboratory.

As for that kind of laboratory product made by legwork, you don't have to think about it to know that there are constant small problems.

But if we don’t hold that briefing, that’s all. After all, most of the time, plans don’t change quickly enough.

"What's their cost?" Hongchuan Feng put the CD player in his lap and started to worry about another question.

“Because we have not officially carried out large-scale production, there will be errors in the current calculation of specific cost details.

But..." Nakajima Heitaro paused, "But judging from the current situation, the cost is not very optimistic."

Hongchuan Feng frowned. The so-called lack of optimism must have caused a lot of pressure on the company to make profits.

"Tell me more about the specific cost issues."

After receiving his permission, Heitaro Nakajima immediately took the table and placed a half-finished CD player on it.

"Junior Brother Hongchuan, you see, because many external mechanisms are designed to withstand earthquakes, they all use metal parts.

Their cost is much higher than that of ordinary plastics, and considering the problem of anti-interference, all external barriers are made of copper sheets as the base material for signal shielding.”

Through the open back cover, Hongchuan Feng can clearly see the outside of the casing. There are many shiny copper sheets wrapping each small module.

Because the CD player does not work on the principle of digital signals, it is different from the tape player and is easily interfered by the outside world and even adjacent circuits.

To ensure the purity of the sound, each modular circuit can be individually shielded.

The most common shielding leg section in electronic products is made of copper material for closed protection.

But when Hong Chuanfeng saw that scene, he shook his head. "Brother Nakajima, that's too extravagant."

"Eh?" Nakajima Heitaro looked at him with some confusion, wondering where Hong's so-called luxury lies.

"Is copper a precious metal? Although the signal shielding effect is very good, it cannot be used that way."

Hong Chuanfeng had to lament that the people who made products in that era were too honest, and all of them were crazy about stacking materials.

"If it's about anti-interference and signal shielding, they can definitely use copper foil."

"Copper foil?!" Nakajima Heitaro felt as if he had been struck by lightning, his shocked eyes seemed to have discovered a new world.

"Of course" Hong Chuanfeng nodded without hesitation, "If we take a step back, even using aluminum is more cost-effective than using copper.

Even more boldly, copper foil paper is no longer used, and aluminum foil paper is used directly.”

"Then...that..." Nakajima Heitaro was stunned.

Is it fun to play like that?

Heitaro Nakajima, who has always been making products honestly, never thought of cutting corners like that?

In fact, it’s not just him. Most of the neon brands now use very conscientious materials.

Otherwise, how can the service life of twenty or thirty years be guaranteed?

Design is one thing, but materials play a bigger role.

Before tomorrow, no one had ever told Heitaro Nakajima that he could save costs in that way.

After all, the design style has been formed over the years, and everyone is accustomed to it and thinks it is natural.

At that time, Neon brands basically attached great importance to the reputation of their products, and never thought about using materials to make legs.

So it suddenly became clear that Nakajima Heitaro was deeply shocked when he heard Benikawa Kaede's method of reducing costs.

"Junior Brother Hongchuan, is that really okay?" Nakajima Heitaro had unconcealable worry in his eyes.

The method was a good one, and the effect was immediate and accurate, but Heitaro Nakajima felt that his conscience was a little hard to bear.
