In addition to high-definition, what other problems need to be solved for home projectors?
First: sound effects
Second: interface
Third: lens wear and running

First: sound effects
Affected by the overall volume of the projector, the built-in speaker is very close to other parts of the machine. When the built-in speaker shows a heavy bass effect, it will cause the parts around the speaker to vibrate together. Such resonance will not only greatly reduce the effect of the subwoofer, but also cause damage to components such as optical machines and boards, and accelerate the wear of the machine.
Second: interface
After comparing many smart home projectors, it is found that some projector brands have really few product interfaces. Basically, only the HDMI interface and the USB interface, like the VGA interface we often use, are basically "ignore". There are two reasons for this design, one is to save costs; second, because the projection volume is too small, if you set too many interfaces, you have to sacrifice the external appearance of the product. However, the consequence of this is that users are inconvenient to use, and many links cannot be realized.
In response to this problem, many projector brands choose to use Bluetooth to connect computers, mobile phones, stereos, game controllers and other external devices to solve. This method does increase the diversity of the link, but seriously, it is more convenient and reliable to connect directly without a connection port. The most ideal solution is to increase the Bluetooth connection function while setting up a variety of link interfaces to enrich the user experience.
Third: lens wear and running
Also in order to reduce costs, most projection products use resin lenses. The advantages of resin lens are low cost and light weight, but it has a fatal weakness is that it is easy to run out of focus when the temperature is high. It is also very annoying for users to constantly adjust the focus during movie watching.
In order to reduce the number of jogs, high-end projection products have improved lens materials and used glass lenses with higher costs. Compared with resin lenses, glass lenses are more wear-resistant and last longer. At the same time, the glass lens is not deformed, does not run out of focus, and has high imaging clarity. Xiaoshuai Cinema U3S not only uses glass lenses, but also 6 combined high-gloss coated glass lenses. At the same time, the lens is equipped with a special lens cover to reduce dust and protect the lens. The details are unique.
In fact, the reason for taking these details seriously is only to have higher requirements and expectations for the rapidly developing smart home projector industry. I hope that the projection industry can really produce products that bring the ultimate user experience.
