We Designed the Small Hi-Fi Box with a Power of Up to 40 Watts (Class-D)
Some customers need small size but high power and multifunctional speaker boxes, so we designed this compact one.
Multiplexed audio sources, support Bluetooth 5.1, USB, SD card, FM stereo radio and line input.
Use 2-inch 20W*2 strong rubidium magnet long-stroke speakers, which are usually used in high-performance HIFI applications.
Built-in TI 50-W dual-channel Class D power amplifier with excellent dynamic response and instantaneous power.
For the power supply, we use a boost circuit to support both 12V power supply and USB power supply (limited by USB input power) , as well as the base power supply.
Ultraviolet, Ozone, Heating, Activated Carbon All-in-One Disinfection Machine
In the early days of COVID-19 disaster, we developed this UV disinfection equipment urgently. Because time is pressing, the device is manufactured with a basic mold without a beautiful appearance.
When users open the top cover, two 30W cold cathode UV lamps can rotate with the shell to sterilize the indoor space.
When users close the top cover, it becomes an air purifier with UV disinfection function. In the front is an all-metal cross-flow fan, and on the rear shell is a removable activated carbon HEPA filter.
After users turn off the air purification function, it becomes a disinfection box. The chassis is a PVC heater, which can sterilize masks, cups, etc. At the same time, strong ultraviolet rays can work together.
There is an ozone generator on the side, which can disinfect indoor space without dead corners.
Therefore, this is an all-in-one three-dimensional disinfection and purification machine, which fully meets the disinfection needs of the family life, avoids microbial contamination, and protects family health.
