Interpreters, as the name suggests, are devices used for interpretation. While their function is similar to that of amplifiers, they differ from amplifiers that simply increase sound volume. Interpreters target the sound, ensuring that recipients within a certain range can hear it, whereas non-recipients cannot.

As the usage scenarios of the presenter expand, many unique applications have been discovered. Today, let's discuss the special usage scenarios of presenters.

In Party and government construction, during various local meetings, or when Party and government leaders visit, it is highly necessary to use interpreters. Interpreters ensure that the meeting content is directly transmitted to participants' ears through the device, so non-participants cannot hear the sound. This not only enhances the efficiency of the event and meeting but also ensures the privacy of the meeting interpretation.

Two unique usage scenarios are museums, exhibition halls, and memorials, among other special locations. These settings carry a certain historical significance. While narrators explain the background stories to visitors, they also set a mood of emotion.

To better convey content to visitors, perhaps through storytelling, tone, background music, or performance, the new Koina speaker can connect to a smartphone via Bluetooth to play background music, creating an atmosphere rich in the essence of the narration.

Another unique application scenario includes resource exploration sites, construction sites, and factory tours. These environments are complex, and during explanations, there might be noise interruptions or other factors limiting sound transmission. The use of the讲解器empowers work in such environments by improving sound delivery.

In scenarios such as travel guides and educational training, the role of an interpreter typically involves outdoor basic guiding tasks. Generally, a tour guide or teacher leads the group, with a group of tourists or trainees following behind. The interpreter's role extends beyond just narration; they are also the team's guide and manager.
