There are crowds everywhere during the holidays, and queues are long for everything. For the audio guide is also more painful, because there are too many tourists, so the audio guide's work also increases a lot of difficulties, always need to shout to hear. If most tourists use audio guides, it might be a lot easier to visit. Why is that? Because the audio guide is an automatic sensing explanation equipment, in the absence of a guide to guide the case, it can also provide consistent explanation for tourists, and tourists listen to the explanation content while visiting, it can be said that it is very convenient.
                                       
                                                                                                                  audio guide

The audio guide is composed of a small signal transmitter and a receiving guide machine, and the signal transmitter is installed in each place that needs to provide voice explanation in the scenic spot or exhibition hall. Moreover, its small size and lithium battery power supply are used, so there is no complicated installation steps and line winding. Another point, if it is in an outdoor scenic spot, then you need to pay attention to the waterproof when installing the signal transmitter, to prevent damage caused by water, after all, there are batteries and other components inside. Tourists only with the received guide equipment, they can realize where they go to hear where, and they do not follow the guide closely like the audio guide, and there will be no loud noise to the environment.
