Mechanical principle teaching display case (computer control, sound control synchronization, CD commentary)
"Mechanical Principles" teaching showcase is an electric teaching equipment designed according to the mechanical principle syllabus of colleges, technical secondary schools, technical schools, and vocational schools. This showcase is divided into ten cabinets and a computer console, and is equipped with a power amplifier, VCD machine and laser film, voice-controlled synchronous demonstration, using a separate drive to control the operation demonstration by a computer or electronic equipment, can be automatically explained by the VCD control sequence ; Can be selected remotely for separate presentation according to teaching materials and teaching needs. Imported organic board is used as the model material; silver-polyester stickers are attached to the board for necessary diagrams and text descriptions. The demonstration image is realistic, the operation is reliable, and the production process is beautiful. Modern laboratory equipment for the application of mechanical courses.
