Seeing everyone's blank expressions, Wu Hao smiled, clapped his hands, and said, "Everyone can try it too, so that they know what's going on."
After hearing Wu Hao's words, everyone also followed the example of Brother Ma before, raising their hands and shouting "Coco" with a smile. Soon, all the people present showed a look of surprise on their faces. It turned out to be like this. Many of them
People even started chatting in the distance.
Wu Hao saw this and said with a smile: "Coco, turn on the regional broadcast function."
OK, sir.
Immediately, everyone stopped and looked at Wu Hao.
"Mr. Wu, why, when I was talking to Coco, they couldn't hear Coco's voice." Xiao Ma asked Wu Hao curiously.
Upon hearing this question, everyone looked at Wu Hao, waiting for his answer.
Wu Hao smiled slightly and explained: This is a major feature of our system and the importance we attach to privacy protection.
When talking to Coco, the system will automatically activate the privacy mode, and only the individual who is talking to Coco can hear her response. This is like creating a private space for everyone's conversation, ensuring that everyone's communication is not visible to the outside world.
interference."
He paused, looked at the expressions of enlightenment on everyone's faces, and continued: "This design not only makes everyone's communication more private and secure, but also allows multiple people to have their own conversations at the same time in different locations.
No interference will occur.
"Wu Hao, how do they plan to apply that technology?" a boss asked curiously.
After hearing Mr. Wu's words, Mr. Zhou showed a hint of disappointment for no reason.
But everyone has developed a strong interest in that technology. As entrepreneurs and businessmen, we have not yet realized that this technology only has a small commercial value and does not have broad application prospects.
scene.
Regarding that question, Tao Hong smiled and shook his head and said: "The advantages of that technology are to clear the way for directional communication and protect privacy, but really compared to the sound quality, if it is as bad as the sound quality of no speakers. Of course, it can also
Listen, I’m just wondering if the effect is that bad.”
Everyone else also nodded along with Mr. Zhou's words and looked at Mr. Wu, with eyes full of eager curiosity.
Targeted communication technology?
With Coco's help, visitors can't get information and solve problems more easily.
At the same time, you are also exploring its application in other areas, such as shopping malls, museums, airports and other public places, to provide people with more convenient and inefficient services."
Then, the microphone array and video surveillance camera are used to lock the position of the person seeking help, and then the angle is adjusted to transmit the sound wave to the head position of the target person. The sound wave is transmitted to the front of the human body, and then resonates with the eardrum, so you can hear it.
sound."
"The most amazing thing about that device is that it adjusts the transmission direction and intensity of sound waves in real time according to each person's position and movement, ensuring that only the target person can hear the sound, and others are completely unable to detect it.
"Mr. Wu continued to explain.
Seeing this, Mr. Wu smiled and said: "Actually, the technology is very complicated. You must have heard of directional communication technology."
After asking Mr. Zhou, Mr. Wu continued: "The principle of that technology is slightly different from that of directional sound technology. It's just that you are more precise in the propagation and control of sound."
After hearing that, everyone nodded one after another. While they were amazed at the technology, they also became even more curious about it. So what kind of technology is it? Why can we hear it ourselves but others can't?
As Mr. Wu spoke, he pointed at this cylindrical white device. Everyone's eyes followed my finger involuntarily, and they all looked at this seemingly inconspicuous device.
Mr. Zhou sincerely praised, "You have heard of directional sound technology before, but this is the first time you have seen such precise control like they do."
Seeing that a few people had blank expressions, Mr. Zhou, who was a little knowledgeable, explained: "Directional sound technology is a groundbreaking audio solution. It provides an ineffective way of sound transmission. It needs to be used."
Small speaker arrays cannot project low-level sound into specific areas to create a specific audio space."
Having said that, Mr. Wu pointed to a cylindrical white device under a monitoring pole at the intersection behind us and said.
Everyone present laughed out loud when they heard Mr. Zhou's question. Everyone knows that Mr. Zhou is a music fan. In order to listen to music, I have put in a lot of effort in that area.
The speaker systems outside are all rated in the tens of millions. I can’t say that I am a real hardcore guy.
How's the sound quality for listening to music? After hearing Tao Hong's words, Mr. Zhou asked quickly.
Before I finished explaining, I turned to Mr. Wu and said: "But as far as you know, that technology cannot achieve the effect you just experienced. It intelligently projects to a specific area, and it is possible to be so accurate that it can reach outside the ear."
.”
Mr. Wu smiled and replied: "At present, you will mainly apply that technology to the park's tour guide and customer service services.
"Well, this is not the sound-generating unit of that technology. Although it is relatively large, there are actually hundreds of ultrasonic sound-generating units integrated inside.
Mr. Wu smiled slightly and said: "Actually, there is still very little potential in that technology that cannot be tapped. For example, you cannot make the sound more muddy and lifelike by adjusting the frequency and intensity of the sound waves; you cannot also combine fewer sound-generating units.
Together, it forms a smaller audio space so that fewer people can enjoy that magical experience at the same time."
"Tao Hong, what kind of technology is that? Don't be too pretentious. Let me tell you slowly." Mr. Zhou urged without hesitation. Obviously, as a music enthusiast, I have a lot of experience with speakers and sounds.
Dealing. I also want to be vague about how it is achieved.
Mr. Wu nodded and said, "What you said is wrong. Special directional sound technology can indeed be so accurate, but which technology must be upgraded or modified?"
Everyone listened to Mr. Wu's explanation with expressions of sudden realization on their faces. It turns out that the magical effect we just experienced was not achieved through ordinary sound-generating devices.
"Wu Hao, that technology is really amazing!"
It’s like being at a large party where everyone can retreat into private conversations with their friends, but are interrupted by other people’s conversations.”
It is an ordinary ultrasonic sound-producing unit. To put it simply, it cannot produce sound on its own. It can only emit some ultrasonic waves. Through ordinary equipment, the sound waves emitted by a few ultrasonic sound-producing units can be concentrated.
At the same time, the intensity of the sound wave will be smaller, the transmission space will be smaller, and the transmission distance will be longer.
