The help that the audio guide system can provide for visiting the exhibition hall.

     On a sunny weekend, Xiao Ming decided to go to the museum to explore the mysteries of history. As soon as he stepped into the door of the museum, he noticed that every visitor had a small device hanging on his ear, listening to the explanation with a smile. Xiao Ming curiously asked the staff what this magical device was? The staff told him that this was a audio guide system, which allows visitors to listen to the explanation more clearly and understand the story and history behind each exhibit. After some explanation, Xiao Ming knew that the original audio guide system was a device that could help the guide introduce. It used scientific and technological technology to improve the problems of noisy sound quality, limited distance, unclear listening, etc. in the traditional explanation method.

     Through actual observation and use, Xiao Ming knew that this audio guide system is divided into two devices for use. One is the transmitter that the guide will hang on his neck, and he will use it to insert the microphone to speak. Then visitors like Xiao Ming will wear a receiver to listen. Not to mention, although the visit time is not short, it is also relatively comfortable to wear. After a normal visit, Xiao Ming felt the magic of this device. No matter how far away he was, as long as he was within the range, he could hear the guide's speech. Through Xiao Ming's story, we can see that the audio guide systemis not only a technical product, but also allows visitors to have a different experience every time they visit.
