Traveling is a way for people to relax in their free time, especially during the summer vacation. Tourist attractions and popular cities are welcoming groups of tourists, and tour guides are also leading groups every day. At this time, if there is a device that can easily lead a group, a audio guide is definitely the best choice. Since the tour guide must lead a large number of people, and the audio guide has the advantage of one-to-many explanations, the tour guide uses it to not only simplify the process of leading the group, but also to easily lead the group. Now many tour guides will no longer use loudspeakers when leading groups, because this kind of equipment not only has mixed sound quality and limited transmission distance, but is also easily interfered and affected, so many times the tour guide has to speak with a hoarse voice.
However, the audio guide uses a special audio transmission channel, so the tour guide does not need to shout loudly, and normal speech or even whispers can be clearly conveyed to tourists. The audio guide is composed of a transmitter and a receiver. The tour guide will use the transmitter to speak, and the tourists will wear the receiver to listen, so the explanation content can be heard clearly, and the listening volume can be adjusted to ensure that everyone can hear clearly. The audio guide also has its own signal range. As long as it is within this range, the volume is the same regardless of the distance from the tour guide. Therefore, the audio guide is not only used in tourism, but also in corporate and factory receptions, and even meetings.
