When visiting scenic spots, you can often encounter tour guides leading groups to visit, but it is impossible for tour guides to lead tourists to visit and explain with their own voices to achieve a good communication effect, so they need to use external equipment. In the past, it was nothing more than relying on loudspeakers, but now it is a audio guide, because the loudspeaker equipment always makes a lot of noise, but the audio guide is a device for explaining without noise. In addition, the sound transmission of large speakers is always limited, and the sound quality is not good. Not only is there no interference in the audio transmission of the audio guide, but the sound quality that tourists listen to is also clear and noise-free. The audio guide communicates the tour guide's explanation content to tourists through digital audio transmission technology. The equipment is divided into two parts: a transmitter and a receiver. The guide will hold the transmitter to lead the group to speak, and the tourists will bring the receiver Listen, while visitors can adjust the listening volume of the receiver.

Because the large speakers in the past used the method of centralized sound amplification and external release, there is no way to control the volume, which will always bring a noisy feeling to tourists who are close. In addition, there is always a situation where there are a large number. At this time, the audio guide has another advantage that it can realize one-to-many non-interference explanations. Using a transmitter can communicate with an unlimited number of people. In this way, even if the number of the team is large, the tour guide does not need to worry, and does not need to adjust the volume of his speech in real time according to the number of people or the interference of the surrounding environment. The frequency of the audio guide adopts the international general 2.4G frequency, and the signal is more stable, even if it is purchased and used by foreign customers, there is no need to worry. The emergence of audio guide not only improves the efficiency and quality of tour guides, but also enhances tourists' experience and fun.
