If there is such a device, it will allow you to know the cultural relics or exhibition points at any time when you visit the museum, isn't it very convenient? The audio guide of the museum can realize such a function, it allows visitors to familiarize themselves with the history of cultural relics in the process of visiting freely. Through the explanation of the audio guide of the museum, visitors can understand while watching, which is very convenient. In the past, when I visited the museum, I could always see the docent with a little bee explaining it. Not only was the noise loud, but when there were many visitors, the docent had to increase the volume. In the long run, it has also caused some damage to the voice of the docent, so the appearance of the audio guide in the museum not only liberates the manpower in the museum, but also protects the voice of the docent.
For visitors, using the audio guide of the museum also has certain advantages over listening to the manual explanation, because listening to the manual explanation always needs to follow the commentator all the time, so the fun of visiting freedom is lacking, and the manual explanation does not considering every visitor, sometimes some content is missed. But the audio guide of the museum does not have such worries. The audio guide of the museum is accompanied by the walk, which can take care of every visitor, it has a certain signal range. As long as you enter this range, the voice of that point will be played automatically, you can also visit freely within the range. The appearance of the audio guide in the museum allows the museum to manage the visitors better without worrying about the lack of docents when there are many visitors.
