Li Shanhe carried the speaker on his shoulder and the guitar behind his back, attracting countless attention along the way. Pen, fun, and www.biquge.info

Finally returning to his apartment, he put down the speakers, just caught his breath, and then turned the drawer upside down.

"I remember it was here, why can't I find it?"

After pouring out all the clutter in the drawer, it finally dawned on me:

"Aha, here!"

In his hand was what resembled a Swiss Army knife.

All-in-one Bluetooth adapter!

In the slender shape, there is a crescent-shaped depression on the outermost side, from which various accessories can be broken out.

“USB2.0，3.0…… 5.0,type-c,tpye-d,type-e......" Every time he made one, he looked at it and finally found what he was looking for:

"Here, the 3.5mm connector for computers and mobile phone speakers!"

Ever since the advent of the Crazy Love 7 and Apple's determination to eliminate the 3.5mm connector, the audio interface has begun to change dramatically. Fortunately, Li Shanhe's universal Bluetooth adapter is multi-functional, and the store has a conscience to keep the 3.5mm interface on it, otherwise it really can't be used.

However, this alone will not work. The 3.5mm terminal is used exclusively in mobile phones and computers, and in this era, only a few speakers with stereo sound are equipped with 6.5mm terminals.

"There is a 3.5mm interface on Bluetooth,And this speaker is very rare to use6.5mmTerminal,In this way,The speaker can be used with Bluetooth!"

This is also the biggest reason why Li Shanhe chose this speaker:

Both of these belong to TRS terminals and can be used universally!

Li Shanhe whistled, found a knife, first disassembled the Bluetooth adapter, marked the location of the 3.5mm connector with a pencil, and then carefully peeled off the wire with a knife, leaving a few strands of thin wire exposed in the air.

It's not so polite to the speaker,He directly cut off6.5mmTerminal,Pull out a few strands of wires of different colors,Compare carefully。

The construction of the TRS series terminals is similar, with the 6.5mm terminals as an example with two insulating rings. The front one is responsible for the right and main channels, the left channel in the middle, and the ground channel at the back.

Then, according to the color, he carefully glued the wires with different functions corresponding to the wires in the Bluetooth adapter with electrical tape.

Whew, he wiped his sweat, and after all this, it was already night. Taking out a bun and biting it, he took out his mobile phone and turned on the Bluetooth module.

"Cortana, look for a Bluetooth device."

A moment later, Cortana's prompt sounded:

"Found a Bluetooth speaker."

YES！

played a long-lost song "Spring River Flower Moonlight Night", and the beautiful violin sound flowed out of the speaker. For a while, Li Shanhe thought that he was back decades later, and he was lying on the tatami mat beautifully, with his hands behind his head, enjoying the beautiful music.

It's a pity that the good times didn't last long, and before a bun was finished, the music began to pop. Li Shanhe got up depressedly, checked it carefully, and found that the tape was taken off.

Li Shanhe scratched his head, since he had confirmed that this magic reform method was feasible, he simply didn't listen, he disassembled the electrical tape and threw it away, restored the Bluetooth adapter to its original state, and put it in his pocket seriously.

"Looks like we'll have to make a 3.5mm terminal myself." He touched his chin and thought, "It's all the same type of terminal, just find a small speaker factory to open the mold for production." Well,Next, we should remodel this speaker.,Who to find......"

Suddenly, I felt that this situation was somewhat familiar, and it seemed that when I bought a car, I also had this kind of thinking.

He laughed, who else is there besides looking for money?

The next day.

The speaker is not small, and it is too stupid to carry it. And he didn't want Hanako to drive, so he went to Kunlun Restaurant first.

After waiting for a long time, Zhang Jie, this kid, came to work with a yawn.

Since Brother Xiao Li left, Zhang Jie has been responsible for leading the takeaway affairs in the store, and more than 200,000 yuan has been received every month. In addition to more than half of it being handed over to parents to subsidize the family, the rest is still a huge amount of money, and it is not possible to get nervous every day.

In the Chinese circle, Zhang Jie is already a high-quality Wang Lao Wu.

"Brother Li, you're here!" As soon as Zhang Jie saw Li Shanhe, his eyes lit up, "What important instructions do you have?" ”

"Get out! It's not a shame to look like a dog! Li Shanhe scolded with a smile.

"It's all thanks to Brother Xiao Li, and it's not a shame to be a dog leg for Brother Li. If Brother Xiao Li can match me with your secretary, it will be even more perfect. Zhang Jie said with a grin.

"If you want to pick up a girl, you go by yourself, I think she likes the sweet and sour fish you make."

Li Shanhe kicked the kid, stopped laughing, and directly offered to borrow a car.

"No problem, Brother Li's business is my business." Zhang Jie patted his chest and packed the ticket, and just like at the beginning, he was a little driver and drove Li Shanhe together.

When I arrived at the garage, I found that the original three-wheeled motorcycle had been replaced by a van.

"The proprietress happily approved a sum of money, and she installed more, and she didn't need to hire any more people, which saved a lot of money." Zhang Jie got on the road, his mouth was still talking, he turned his head and asked, "Brother Li, you haven't said where to go?" ”

"Go to Qian Laohei's place." Li Shanhe patted the stereo behind him and said.

"Money, money?" Zhang Jie stammered in fright, "Xiao, Brother Li, let me tell you Brother Li, Qian Laohei is definitely a murderer!" I have seen his booth at the University of Tokyo, and there are bright objects under the oiled paper, and when he walks up, it must be a watermelon knife! ”

"It can't be a kitchen knife? So much nonsense, drive well, I'm here, I can't kill you. ”

Not to mention Zhang Jie's depression, like last time, he opened a TJ restaurant in the suburbs.

Business here is still not very good, and most of them are truck drivers who run transportation outside. Li Shanhe and the waiter asked for directions, and walked to the inner courtyard with his speaker.

Avoiding the poultry on the ground, it was still the small courtyard full of sundries, Li Shanhe saw Qian Laohei, who was sharpening his knife on the grinding wheel, and another young man in his early twenties, squatting aside to feed the chickens.

Li Shanhe didn't do much nonsense, and put the speaker on the ground: "Boss Qian, I want to transform this thing." ”

The young man who fed the chickens took one look at him and went on with his work. And Qian Laohei stopped what he was doing and walked over to look at the speaker.

"How?" He asked hoarsely.

"Have you ever seen a trolley suitcase? Just change it like this, so that the speaker can be put in, and you can drag it away. The opening at the back of the trunk should be exposed, and finally, the speaker should be changed to a battery-powered one. ”

Qian Laohei listened and wrote it down, and finally frowned: "It's very troublesome to change the circuit, I don't understand." ”

"It's okay, I know." Li Shanhe smiled, "Let's just do it together." ”

"You know the circuit?" Qian Laohei looked at him in surprise.

Isn't it just the knowledge of high school textbooks, and you can learn it by disassembling the radio or something according to the manual...... Li Shanhe patted his head and remembered that in this era, it stands to reason that he was a cattle herder before the age of sixteen, and a cook after the age of sixteen, so he shouldn't know these advanced knowledge.

"I'm studious, can't I?"

Li Shanhe snorted and fooled this paragraph.

Qian Laohei and the young man who fed the chickens glanced at each other, and the young man went to get the account book and calculated the account: "Bring your own suitcase, you can get the circuit yourself, Lao Qian works for about 4 hours, and charges you 1,000 yen." ”

It turned out that this person was in charge of the accounts.

Li Shanhe nodded, 1,000 yen was a small amount of money for him at this time, and he was just about to pay the bill, when he suddenly slapped his forehead: "I forgot, Boss Qian, can you add a record player to it?" ……”
