Lifting cabinet type integrated multimedia teaching machine capable of being used in mobile mode

Abstract

The invention provides a lifting cabinet type integrated multimedia teaching machine capable of being used in a mobile mode and belongs to the technology of computer multimedia device development. The machine is mainly composed of a machine cabinet (1), a machine cabinet case (2) which is called a machine case for short and an integrally-arranged electric lifter. The machine cabinet and the machine case are connected into a whole through the lifter, the core components such as a displayer, a voice box, a power amplifier, a computer, a center control system and an externally-connected port are installed in the machine cabinet in an integrated mode and the machine cabinet can be lifted from the machine case or descend to the machine case according to the requirements; a lockable top cover and a base are arranged on the machine case and universal wheels are installed on the lower face of the base. The lifting cabinet type integrated multimedia teaching machine has the practical advantages that the integration level is high, the seeing and hearing effect is good, the machine can be used in the mobile mode, management is convenient, the functions are complete, control is convenient, and the machine can be widely applied to various indoor and outdoor occasions for teaching, training, meeting, propaganda, entertainment activities and the like.

Description

technical field [0001] The invention belongs to the development technology of computer multimedia equipment, and in particular relates to a production scheme of a liftable cabinet-type integrated multimedia teaching machine that can be used freely. Background technique [0002] With the rapid development and popularization of computer technology and the continuous progress of multimedia technology, multimedia teaching, as an auxiliary teaching method, is playing an increasingly important role in the field of education and teaching with its many advantages. Multimedia teaching is mainly through the combination of computer (computer) and various peripheral audio-visual equipment, and uses various media information such as text, sound, and image to act on students, so as to optimize the teaching effect. [0003] Existing multimedia teaching equipment is bulky, scattered in structure, takes up a lot of space and is not suitable for mobile use. Therefore, the multimedia teaching ...

Problems solved by technology

[0004] On the other hand, due to the indirect display principle of the combination of computer, projector and screen, the existing multimedia teaching equipment will inevitably be affected by various external objective factors.

First of all, the most influential factor is the intensity of ambient light. Hanging curtains is the best way to solve this problem at present, but doing so will lead to dim light and cloudy air inside the place of use to varying degrees. Long-term use will make you feel dizzy , which is detrimental to the eyesight and health of the user

Secondly, the dust on the lens of the projector is also a factor that cannot be ignored. Since the projector is generally suspended at a high position, it is inconvenient to wipe it frequently. become worse

[0005] In addition, for those schools with a low utilization rate of multimedia equipment, especially the majority of grassroots primary and secondary schools, even if each classroom is equipped with equipment, it will often be idle and unable to be used, resulting in a waste of capital investment and teaching resources. Only when it is used according to the need, can the multimedia teaching equipment be used reasonably and effectively to maximize its effect
