[0002] In the field of education, teaching tables are an indispensable part of students' daily learning. Their design and function directly affect students' comfort, concentration and overall learning effect. Traditional teaching tables have a simple structure and usually only provide basic writing and book placement space, which fails to fully consider the changing needs of modern teaching environments. With the advancement of educational concepts and the development of technology, the requirements for teaching tables have gradually shifted from single functionality to multifunctionality and intelligence.

[0003] In recent years, with the accelerated advancement of modernization, the design of desks has been constantly innovating and improving in order to provide students with better learning conditions. For example, new desks have begun to incorporate ergonomic principles to optimize students' sitting postures and reduce physical fatigue caused by long-term study. At the same time, some smart desks have also integrated electronic equipment interfaces to support the application of digital teaching materials to meet the increasingly popular needs of information technology education.

[0004] However, under the existing teaching model, especially when multimedia teaching is more and more widely used, the traditional classroom layout has exposed some problems. Multimedia teaching is popular among teachers for its intuitive and vivid characteristics, and has become an important part of classroom teaching. However, in actual operation, since the student seats in the classroom extend from the front row to the back row, the distance from the multimedia blackboard (or projection screen) varies significantly, making it difficult for students in the back row to clearly see the content displayed on the podium. This phenomenon not only affects the visual experience of students in the back row, but more importantly, it hinders their understanding and absorption of knowledge. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent multi-purpose teaching and training table, which can synchronize teaching content to the desk, so that knowledge transfer is not limited by distance, and students in the back row can also absorb classroom knowledge well.
