With people's attention to the construction of spiritual civilization, the exhibition industry has begun to develop gradually, and the number of people who like to go to the exhibition hall to study and Xi has gradually increased. Rather than going to see the text introduction next to the exhibits one by one, groping to learn Xi knowledge about the exhibits, more people are more willing to have professional and richer explanation services, so that they can obtain knowledge more easily. Nowadays, with the advent of various new technologies, it has become a popular trend for visitors to seek more convenient guided tours during their visit to the exhibition hall in order to have a more comfortable visiting experience.
When people visit an exhibition hall, sometimes in the face of those unknown exhibits and display panel introduction, many people will be eager to know more content and explain the exhibition items, so many exhibition halls will train and provide special interpreters to provide services for visitors. When faced with a large number of visitors who need explanation, the exhibition hall will use the guide equipment that can provide explanations for a large number of people, that is, the team explanation system, to provide guided tours for visitors.
The team explanation system is composed of a narrator with a guide machine, and a visitor with a receiving device to listen with a headset. As an important equipment in the observation work, the guests wearing the receiving equipment can clearly hear every word of the interpreter within a radius of 1-150 meters from the interpreter, regardless of the position, and the free movement does not affect the quality of the reception. In the application, the narrator carries the interpreter to explain through the ear hook or lavalier, and the listener uses the receiving device to connect the headset to listen, and if it is a Bluetooth headset receiving device, it can be worn directly in the ear to listen.
Compared with other interpretive equipment, the group guide system is a kind of guide equipment specially used for receiving groups, and it has a wide range of applications and is used in many fields.
