[0002] With the development of science and technology, various industries have continuously upgraded various advanced modern scientific and technological equipment in communication and exchange.

While the receptionist provides considerate explanations to the front-row officials, the accompanying officials in the back row cannot enjoy the same treatment; when holding large-scale meetings, traditional amplifying equipment cannot achieve 3D surround sound to meet the needs of all participants; when companies receive visitors, although general interpreters can meet the voice transmission needs of small teams, their appearance is traditional and old-fashioned, affecting the corporate image of the company; when visiting factories, in a noisy environment, many teams still use traditional loudspeakers for explanation and communication; when tour guides lead groups and give explanations, general tour guide interpreters cannot achieve long-distance transmission.
