Problems solved by technology

With the development of science and technology, micro-projectors that are exquisite, portable, miniaturized, entertaining, and practical have appeared, which are more convenient for business office, teaching, and business trips, and can replace TVs to achieve the effect of home theaters. However, , Generally, projectors do not have audio functions, and need to use speakers to play sound, while projectors with audio functions have poor audio effects, and need to use speakers to play good sound effects
In addition, when using a micro projector to play images or videos, it is necessary to use a tripod to fix it. However, when we need to play audio and video when we are on a business trip or going out, it is not necessary to carry three independent instruments of the projector, speaker and tripod at the same time. very convenient
