Description

Technical Field

[0001] The utility model relates to the field of projection screens, in particular to a self-sounding projection screen. Background Art

[0002] A projector is an optical instrument that uses optical elements to magnify the contour of a workpiece and project it onto a screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of blind holes and observe the surface of parts. Projectors are particularly suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears, and forming tools. They have high inspection efficiency and are easy to use. They are widely used in metrology rooms and production workshops, and are particularly suitable for instrumentation and watch industries.

[0003] Projectors are widely used in homes, offices, schools and entertainment venues. According to different working methods, there are different types such as CRT, LCD, DLP, etc. At present, most multimedia audio-visual systems that display through projection are composed of projectors, projection screens, sound amplification speakers and control systems. The sound of the projection screen needs to be produced by the sound amplification speakers. The projection screen and the sound amplification speakers are separate structures, resulting in more equipment constituting the entire multimedia adaptation system, which is inconvenient to use.

[0004] In summary, we propose a self-sounding projection screen to solve the above problems. Utility Model Content
