Abstract

The invention relates to a teaching instrument for amplifying micro characters or objects, namely a classroom demonstration display amplifier. The classroom demonstration display amplifier consists of a lens, a microphotograph amplifier, a definition adjusting button, a bracket, a photographing and amplifying adjustor, a microphone, a display platform, a display and the like. The classroom demonstration display amplifier is characterized in that: the microphotograph amplifier and the microphone are electrically connected with the display; the microphotograph amplifier is arranged on the bracket; the bracket is fixed on a shell of the display; the photographing and amplifying adjustor for adjusting the size of an amplified object is arranged on the bracket; and the display platform for holding the amplified object is arranged above the display. According to the classroom demonstration display amplifier, the reading scales, circuit diagrams and the like of micro objects such as a diode or a universal meter can be amplified, so that students can see clearly, therefore the classroom demonstration display amplifier is a good helper for a teacher during teaching, and the effect of a classroom can be greatly improved; and the classroom demonstration display amplifier is particularly suitable to be used in rural schools and the like.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a display and playback instrument for classroom demonstration. Background technique [0002] The existing classrooms are relatively large, and the students at the back are in the classroom and cannot see clearly the experimental content demonstrated by the teacher. Sometimes the teacher speaks in a low voice and is difficult to hear clearly, which affects the teaching effect. Only the projectors in multimedia classrooms can magnify tiny text, pictures or objects, but the investment in multimedia equipment is high and expensive, and it is difficult for many schools to purchase, especially in remote mountainous villages, and there is no condition to configure it. Contents of the invention [0003] The purpose of the present invention is to provide a kind of classroom display display instrument for teaching for vast schools such as rural areas for this actual situation. The present invent...
