Description

A digital media teaching projector

technical field

The utility model relates to the technical field of projectors, in particular to a projector for digital media teaching.

Background technique

A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, and can also be used to measure the surface shape of a non-through hole and observe the surface of a part with reflected light. The projector is especially suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc. It has high inspection efficiency and is easy to use; it is widely used in measuring rooms and production workshops. It is especially suitable for the instrumentation and watch industry. Projectors are currently widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP.

When schools conduct digital media teaching, they often use projectors to assist teaching and help students better understand the content of the classroom. However, most of the existing projectors are placed in a storage box, which is suspended by a boom. At the top and bottom of the wall, it is inconvenient to adjust the projector, and if the projector is directly hung on the top of the classroom, it will bring a greater safety hazard if it is not fixed. In addition, the projector will produce Heat, the general projector does not have a good heat dissipation effect when it is used. If things go on like this, it will cause damage to the circuit components in the projector and reduce the service life of the projector. Therefore, in order to solve such problems, we propose a digital Projector for media teaching.
