A month ago, Hong'er used a "DVD" to play a series of "Wonderlands on Earth" in the chief's model room, and said that these are the scenery of the Lion Country not far from Bo Ni, in fact, these scenery pictures are those computer desktops that Huangshi downloaded from the Internet, but since they can be used as desktops, they are naturally beautiful and fresh style.

For example, the sky and clouds were rendered with filters in PS, the Gaussian blur effect was used for distant islands, and the reflection filter was used to create the reflections of islands and plants in the water, and at last they became very beautiful dreamy ocean landscapes.

Such a dreamlike scenery is irresistible even to well-informed modern people, not to mention those who can say that they don't even know what PS is, and the pictures and tones of each landscape are not repeated, and they are all so refreshing.

Faced with this kind of beauty, Li Chengpeng, who was the most literally literate at this time, lost the verses describing them, and only remembered a poem, "This scene should only exist in the sky, how do you know that you are in the wonderful peak?" ”

And Jiang Laogan couldn't take their eyes off it, and they couldn't wait to take out their eyeballs and embed them in the painting, muttering to themselves, "I'm afraid this is heaven, it's the fairy world." ”

After Hong'er switched these beautiful pictures several times, these people held back their excitement and sighed, this beautiful scenery in the world made them yearn for it, thinking that maybe one day they could go there to live for a few days, and it would be in vain.

Therefore, later, when Hong'er introduced them to all kinds of electrical appliances, she didn't have that excitement, and only listened to Hong'er introduce in the living room, "This is 'speaker', it's '5." 1 surround stereo speaker', the chief said it was used to listen to tunes. ”

Hearing her say this, everyone noticed that there were several delicate gadgets on both sides and above the TV, on both sides of it and on both sides of the sofa were two small cylinders about the height of a TV, and then there was a square black box on the glass plate above the TV, and there was a small round hole above the box.

Listening to Hong'er continued, "This is a 'mid-to-high speaker', and this is a 'subwoofer'." ”

In fact, even Hong'er herself didn't know what "middle and high tones" and "heavy bass" were, and she could only repeat what Huang Shi said according to the script, and the others were naturally confused, so they heard Zhang Chen ask, "Miss Hong'er, what are 'middle and high tones' and 'heavy bass'?" ”

Mid-treble and heavy bass This is the concept of sound frequency, Huang Shi has no way to explain it to Hong'er, but after having the sound disc, it is much simpler, so Hong'er took out a few small discs from the TV cabinet, "The chief said, this is the 'test disc' of the CD, which can be used to test the clarity of the sound, and can also test the 'stereo surround effect' of the sound." ”

"Miss Hong'er, aren't these plates the same as the ones before?" When Li Chengpeng saw that the two discs were exactly the same, he wondered why one was called "DVD" and the other was called "CD".

Hong'er returned the disc from the DVD player and replied, "The disc in my hand is called a 'CD', and now it only has sound, while the 'DVD' in front of it can have pictures and sound at the same time." But the chief said that the sound quality of this 'CD' would be better. ”

As the first generation of laser playback systems, CD has undergone the evolution of VCD and DVD, and it has remained until now, and has not withdrawn from the stage of the masses like the earlier video recorders. And it not only does not retreat but is more brilliant, with a new carrier and player SACD, compared to CD, HDCD, SACD adheres to the sound quality of CD, and there are 5. 1 and 7. 1-channel format.

DVD, on the other hand, adds an additional video signal to the CD, although it is much clearer than the VCD. But the sound quality is nowhere near as good as a CD. Because the video signal has to be compressed at high frequency, it is destined that there must be video signal processing in the playback system, which affects the audio signal. No matter how well it is shielded, the digital signal will go through the same channel, so this gap is doomed.

Hearing Hong'er say this, everyone has a lot of interest again, but the DVD disc just now has given them a lot of stimulation in terms of "color", so I don't know what kind of surprise this current CD record can bring to everyone in terms of "sound".

……

The living room of the model house is already very large, 16 square meters, but seven or eight people standing in the middle of the room, it seems a little crowded, but they don't notice these now, they see that the TV screen in front of them, what appears is not those beautiful scenery, but a string of jumping elves, but there is no sound in those "speakers".

Just when everyone was wondering, they heard the sound of rain coming from outside the window, and gradually it grew from far and near, from small to large, so that they could all see the raindrops falling on the ground, splashing and dust like bubbles.

An Ruyi waited for a long time, and didn't see the song coming from the speaker, but waited for the long-lost autumn rain outside, thinking that it hadn't rained for a long time, but as soon as the thought came up, he remembered another thing, so he hurriedly said, "Hong'er, I have to go back first, and I have to collect the clothes drying on the balcony." ”

As soon as she spoke, the others immediately remembered that their clothes were hanging outside, and they all spoke to Hong'er.

"Yes, Miss Hong'er, our clothes are still hanging outside."

"Why is this rain so weird......"

"Hehe, don't panic, it's not raining outside at all, and the sound of the rain comes from here." Hong'er hurriedly stopped them, and then pointed to the small cylindrical speakers, "Pay attention to yourself, if you came out of here." ”

The people who came to their senses only then remembered that something was wrong, it turned out that the doors and windows of the room were closed, how could the sound of rain outside come in so loudly, as if they were in the rain just now, and the sound of every drop of rain was clear to their ears, as if it was dripping under their feet.

Niu Dali leaned next to a loudspeaker, a cylindrical speaker with a speaker mounted on the side wall in the middle of the cylinder. The owner of the audio equipment store said that the structure of this speaker is simple, the cylinder of the cabinet is formed at one time, the rigidity is better, it can really eliminate the resonance and make the standing wave disappear, and the arc-shaped cabinet surface, can also effectively eliminate the surface sound coloration, at high power, the cabinet will never be distorted, can make the sound more pure, clean and smooth.

While capturing the source of the rain, Niu Dali carefully looked at the long silver-gray pillar, which was slender and elegant, and looked noble and elegant. The silver cabinet glows with metallic sheen, black and white boldly divide the space, and the sound comes from the black grid in the middle, "Hey, you see, it's really coming out of here." ”

All of a sudden, he was surrounded by people, all tilting their heads sideways, trying to hear a word, and sure enough, a "tick, tick" sound came from that place, "Hehehe, it's really interesting." ”

And the people gathered around the long pillar, listening with great interest to the sound of the raindrops inside, and in a moment the sound of the rain grew louder and louder, as if it were blowing out of the black grid of the long pillar, and blew far away from them.

Suddenly, a loud "boom" sounded behind everyone, and everyone seemed to see a silver lightning bolt, cutting through the dark sky, "crackling" from the sky, and they all hurriedly covered their ears.

Hong'er has heard it many times, and she didn't get in front of that speaker like others, so she was naturally not frightened, and now she saw that some people were pale, so she smiled and said, "Hehe, you guys go down and listen." ”

Qu'er covered her chest, patted it gently, and stuck out her tongue at Hong'er, "I'm scared to death." ”

"Hee-hee."

After a while, the thunder "rumbled" away, the clouds dispersed and the rain stopped, and everyone heard the sound of running water from behind, and closed their eyes, as if they saw the mountain stream after the rainstorm, flowers and green grass, cicadas chirping and birds, wind and rain marks, all beside themselves, and a clear spring flowed between the clean rocks, making a "whoosh" sound.

"Tut-tut, this 'speaker' is really amazing." Zhang Chen shook his head with satisfaction, everyone believed it when it was raining just now, but when it thundered, their faces changed in fright. Now that I listened closely, the birds seemed to be in the forest, jumping from tree to tree, and there was a crisp and loud chirping sound, and the "murmuring" water surrounded the mountains.

Then, Hong'er changed several "test discs", but unfortunately it is no longer a natural sound, but just some music discs, which are their own brand CD records produced by audio equipment manufacturers, generally select a variety of representative music for strict technical processing, and limited production and distribution, used to test the quality and effect of their own audio products, hoping to obtain the praise of audiophiles for their own brand audio with the best sound effect.

Among these CDs known as test discs, HI-FI audiophile discs and APE Huiwei test discs are the most famous, but Huangshi didn't buy that kind of audiophile-level audio, that level of audio is tens of thousands or even hundreds of thousands, Huangshi doesn't know the goods, naturally he won't buy it, he just chose a 2699 yuan "5. 1 surround stereo speaker".

Although this kind of audio is cheap, it also has its own characteristics, such as the innovative IFP focus ring design, the Inspire T6160 extended IFP focus ring design can effectively improve the directivity of the sound and ensure the accuracy of the tone, so that the listener can hear more clearly. The innovative PhaseCap, with its bullet-cone-shaped dust cover design, makes the high frequencies purer and the mid frequencies clearer, especially in movies and games.
