"Hahaha!"

Duan Yun laughed when he heard this.

"What are you laughing at?" the young man in the trench coat was stunned for a moment when he saw this.

"It's nothing, let me tell you this, this kind of tape recorder in your hand is just a toy in my eyes," Duan Yun raised his eyebrows and said.

Saying that the tape recorder bought by others for hundreds of yuan is a toy, which will obviously arouse the anger of the other party, with Duan Yun's emotional intelligence, he usually wouldn't talk like this, but this time he obviously deliberately provoked.

"You say my tape recorder is a toy!?" Sure enough, as soon as Duan Yun's words fell, the young man in the trench coat suddenly sank his face.

"Listen to me first. Duan Yun smiled slightly, and then said: "I also see that brother, you are a master of playing audio, the standard for rating a top speaker in the world is the resonance rate of sound quality, you should know this, right?"

"Of course I know!" The young man in the trench coat was stunned for a moment when he heard this, and then nodded.

"That's good. Duan Yun said in his heart, you know what a fart! What is the resonance rate Duan Yun himself doesn't know, it's purely that he made up a cold word to fool the layman, but as a result, when this windbreaker heard Duan Yun praise him as a master, he didn't know how to pretend to understand the trick, so Duan Yun continued: "You wait for me to tune my speaker again, you listen."

As Duan Yun spoke, he squatted down and turned up the bass frequency of his speaker.

"Jump card!

After the bass frequency was turned up, the onlookers suddenly felt an indescribable feeling of excitement, as if their heartbeat had instantly accelerated a lot.

The young man in the trench coat was stunned for a moment when he heard the voice after the frequency conversion, he obviously didn't expect Duan Yun's speaker effect to be so good.

"How do you feel?" After a moment, Duan Yun said to the young man in the trench coat with a smile.

"Make do with it. The young man in the trench coat said, put his tape recorder on the ground, and said to Duan Yun: "But your sound effect is still worse than my Sanyo."

The next moment, the trench coat also put a dance music tape into the tape recorder, and when the button was pressed, a pleasant sound immediately rang out.

After hearing the dance music of the Sanyo tape recorder, there were immediately a lot more onlookers.

I have to say that this imported Sanyo tape recorder is indeed much better than other brands of tape recorders.

In terms of hardware configuration, in addition to the complex circuit design and many tuning functions, this Sanyo tape recorder is four speakers, and there are two more small speakers to enhance the treble part than the general tape recorder, so the sound quality sounds transparent and clear, and it is a lot more delicate, which can be regarded as a high-grade tape recorder in this era.

But even so, compared with Duan Yun's subwoofer, limited by the size of the recorder speaker, the small speaker cannot reflect the perfect bass effect, so in the bass part, Duan Yun's speaker is absolutely dominant.

"How's it going? It's better than your speaker. Seeing more and more onlookers, a touch of pride flashed on the face of the young man in the trench coat, and then said: "So don't blow about how good your speakers are in the future, and the subwoofer"

"Do you know why my speaker is called a subwoofer?" Duan Yun asked with a smile.

"Why?"

"I also told you just now,The international evaluation of the grade of a speaker,One of the key indicators is the resonance rate of the sound effect,As a master of playing audio,This basic common sense must be known, right?" Duan Yun asked with a smile.

"Of course I know!" Seeing the crowd of onlookers next to him, the young man in the windbreaker who was labeled as a 'music master' by Duan Yun obviously didn't want others to see the details that he hadn't actually finished elementary school.

"Let's put it this way, the speaker with a strong resonance rate can bring a strong shock to the audience, like a landslide cracking, Jiang Tao is rolling, this is an epic sound effect!" Duan Yun paused, then pointed to the glass window of the opposite shop with his hand and said, "Let me ask you, can the sound of your tape recorder shatter the glass on the other side?"

"How is this possible?" the young man in the trench coat was stunned when he heard this, and his head shook like a rattle.

The young man in the trench coat has been buying this tape recorder for a few months, and he usually doesn't say that the volume is turned on to the maximum at home, and the window glass is not broken at all, so in his opinion, it is simply impossible to use the stereo to shatter the glass!

"I can do it with this speaker!" Duan Yun said with a raised eyebrow.

"!" the young man in the trench coat glanced at Duan Yun.

Everyone else present also showed a disdainful smile.

Obviously, once again, everyone obviously felt that Duan Yun's boast was a bit too big.

Everyone has seen a tape recorder, and many people have it at home, but the fact that a sound can shatter glass is a bit too incredible for many people.

"If only this speaker could really shatter glass"

"Then I'll buy you a speaker for 600 yuan!"

"Okay!" Duan Yun nodded when he heard this, and said again: "In addition, you have to pay for the glass." ”

"It's nonsense, come quickly. The trench coat took out a few large solidarity sheets from his pocket, patted them in his hand and said, "This money is enough to pay for glass, right?"

"Good!" Seeing this, he immediately changed a tape and plugged it into the tape recorder, and pressed the button.

"Jump card!

Loudspeakers heard the fast-paced dance music again.

"That's it" Seeing that the glass on the other side did not react, the corners of the young man in the trench coat hooked up and said.

Duan Yun didn't pay attention to the mockery of the trench coat, but squatted down and adjusted the bass frequency to the highest.

"Buzz!"

After Duan Yun turned the knob to the maximum, the entire speaker was turned on and vibrated slightly.

"This"

Before the young man in the trench coat who was facing the speaker speaker, he felt his heartbeat suddenly accelerate, and the hairs on his body stood up!

The onlookers also instantly felt that the music coming out of the speakers had an unprecedented strong feeling, as if they were in a battlefield full of artillery fire, almost every drum beat in the music could make their whole body tremble, this shocking feeling was absolutely unprecedented!

At this time, Duan Yun slightly adjusted the direction of the lower speaker speaker and aimed at the window of the grocery store across the street.

"Buzz!"

After a while, the glass of the opposite window had begun to vibrate at a high frequency visible to the naked eye, and the old putty on the top of the window began to crack and fall.

"Whoa!"

With a crisp sound, a piece of glass in the upper left corner of the window shattered and fell first, causing the two saleswomen inside to scream loudly.

When Duan Yun saw this scene, he immediately turned off the power of the tape recorder.

Everyone present was stunned by the scene in front of them, and the young man in the trench coat who was squatting on the ground simply sat on the ground!

"Brother, I'm convinced, I bought this speaker!"

After half a ring, the young man in the windbreaker who came to his senses hurriedly got up and said to Duan Yun.
