There is a driver inside the music T-shirt that uses a connecting cable to control the light of the picture. The two ends of the connecting cable are pin-type, each connected to the picture and driver. They can be freely disassembled during cleaning. They are not fixed in the music and therefore cannot be disassembled. There are two types of drivers, adjustable voice-activated driver and five-flash driver. They are both powered by AA alkaline batteries and can be controlled to continuously emit light for 5-6 hours each time. Types and differences of music T-shirt drivers: Adjustable voice-activated driver---Adjust the small knob next to the driver according to the external sound volume to control the sensitivity of the light and flash. Use 4 AA batteries. 5-flash 8-segment drive --- non-voice control, manually adjust the small button and gear next to the driver to control the luminous flashing effect. 8 flashing modes can be manually selected. Use 2 AA batteries. Music T-shirts use different drivers, and the use of adjustable voice-activated drivers: First, when installing 4 AA batteries [the positions must be correct], pay attention to the positive and negative levels of the connecting wires. Then turn on the switch. If the driver is connected and there is no flickering, first check whether the connection and the driver are plugged in reversely, then connect them in the opposite direction, and finally adjust the knob next to the driver to see the sensitivity of the flickering. To use with a five-flash driver: First install 2 AA batteries and turn on the switch. The small round button next to the driver can adjust different flashing modes, and the gears below the small round button can adjust different frequency bands. Music T-shirt technology The difference between the Velcro type and the stitched type 1. The Velcro type uses Velcro to stick the cold light sheet on the music. It can be removed and washed at will. For spring outings, the advantage is that it is easy to remove and wash. You can buy pictures of the same size. You can only buy one piece. For music, buy a few patterns you like and change the pattern at will. The disadvantage is that the overall effect is not as good as the stitched one, and part of the cold light sheet protrudes outside the music. 2. The suture type completely integrates the cold light film with the clothes, and the cold light film cannot be removed. The advantage is that the overall effect is good-looking, like a kind of jewelry on the chest. The disadvantage is that it can only be washed by hand when disassembling and washing, and the cold light film cannot be immersed in water. .
