Seeing everyone's blank expressions, Wu Hao smiled, clapped his hands, and said, "Everyone can try it too, so you know what's going on."

After hearing Wu Hao's words, everyone also raised their hands and shouted "Coco" with a smile, just like Brother Ma did before. Soon, the faces of the people present showed expressions of surprise. It turned out to be like this. Many 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.

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 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 disturbed by the outside world. "

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. There will be no interference.

It's like being in a large party where everyone can have private conversations with their friends without being interrupted by other people's conversations. "

After hearing this, everyone nodded one after another. While they were amazed at this technology, they also became more curious about it. What kind of technology is this? Why can they hear it but others can't?

"Mr. Wu, what kind of technology is this? Don't hold back and tell us quickly." Mr. Zhou urged anxiously. Obviously, as a music enthusiast, he has been dealing with speakers and sounds a lot. He also wanted to figure out how this was achieved.

Everyone else followed Mr. Zhou's words and nodded and looked at Wu Hao, their eyes full of eager curiosity.

Seeing this, Wu Hao smiled and said: "Actually, the technology is very simple. You should have heard of directional communication technology."

Targeted communication technology?

Seeing that most people had blank looks, Mr. Zhou, who was a little knowledgeable, explained: "Directional sound technology is a groundbreaking audio solution. It provides an effective sound transmission method without the need for large-scale sound transmission." Speaker arrays can also project sound to specific areas in a highly directional manner, creating a specific audio space.”

After explaining, he turned to Wu Hao and said: "But as far as I know, this technology cannot achieve the effect we just experienced. It is intelligently projected to a specific area, and it cannot be so accurate to the ears. "

Wu Hao nodded when he heard this and said: "You are right. Ordinary directional sound technology cannot achieve such accuracy, but what if this technology is upgraded and improved?"

After asking Mr. Zhou, Wu Hao continued: "This technology is similar to the principle of directional sound technology, except that we are more precise in the propagation and control of sound."

Speaking of this, Wu Hao pointed to a cylindrical black device on a monitoring pole at the intersection not far in front of them.

“Well, that’s the sound-generating unit of this technology. Even though it’s relatively small, it actually has hundreds of ultrasonic sound-generating units integrated inside.

This is a special ultrasonic sounding unit. Simply put, it cannot make sound on its own. It can only emit some ultrasonic waves. Through special equipment, the sound waves emitted by multiple ultrasonic sounding units can be concentrated together. , as a result, the intensity of the sound wave increases, the transmission space is reduced, and the transmission distance becomes longer.

Then the microphone array and video surveillance camera are used to lock the position of the person seeking help, and then adjust the angle to transmit the sound waves to the head position of the target person. After the sound waves are transmitted to the human body, they will resonate with the eardrum, and we will hear the sound. "

As Wu Hao spoke, he pointed at the cylindrical black device. Everyone's eyes followed his finger involuntarily and looked at the seemingly inconspicuous device.

"The most amazing thing about this device is that it can adjust 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." Wu Hao continued explained.

Everyone listened to Wu Hao's explanation with expressions of sudden realization on their faces. It turns out that the magical effect they experienced just now was achieved through this special sound-generating device.

"Mr. Wu, this technology is really amazing!"

Mr. Zhou sincerely praised, "I have heard of directional sound technology before, but this is the first time I have seen such precise control like yours."

Wu Hao smiled slightly and read www. uukanshu.net said: "Actually, this technology still has a lot of potential that can be tapped. For example, we can adjust the frequency and intensity of sound waves to make the sound clearer and more realistic; we can also combine multiple sound units to form a A larger audio space allows more people to enjoy this magical experience at the same time.”

How about the sound quality for listening to music? After hearing Wu Hao's words, Mr. Zhou asked quickly.

Everyone present couldn't help laughing after hearing Mr. Zhou's question. Everyone knows that Mr. Zhou is a music fan. In order to listen to music, he has put a lot of effort into this aspect. The speaker system in his home alone is worth tens of millions. It can be said that he is a real **** boss.

Regarding this question, Wu Hao smiled and shook his head and said: "The advantages of this technology are directional transmission and privacy protection, but in terms of sound quality, it is definitely not as good as the sound quality of speakers. Of course, you can also listen , but the effect is not that good.”

After hearing Wu Hao's words, Mr. Zhou couldn't help but show a look of disappointment.

But everyone has become very interested in this technology. As entrepreneurs and businessmen, they have clearly realized that this technology not only has huge commercial value, but also has broad application prospects.

"Mr. Wu, how do you plan to apply this technology?" one manager asked curiously.

Wu Hao smiled and replied: "Currently, we mainly apply this technology to the park's tour guide and customer service services.

With Coco's help, visitors can more easily obtain information and solve problems.

At the same time, we 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 efficient services. End of chapter)
