This is the patent product of our company, the Moveable Language Laboratory System, and also is the Infrared Frequency-Modulation System for teaching, studying and examining languages.  It not only has the basic function of language laboratory as communicating easily among the different units, but also has more other advantages, such as being moved easily as the wireless equipments (not occupying the immovable places in the classroom), being changed the student units freely, and costing much less than the normal system. At the same time, the host machines in different classrooms can be associated to use for large-scale examinations. This is an excellent scheme for the assembly function of several units, including the Moveable Language Laboratory as the teaching and studying system for oral language, the Infrared audition sub-system as the main system for teaching and examining languages, and the frequency-modulation sub-system as the exercise system outside classes and the standby system of examination
