Background

A usb disk is one type of flash memory, and is sometimes referred to as a flash disk. The largest difference between the USB flash disk and the hard disk is that the USB flash disk is plug-and-play without a physical driver, and is convenient to carry. The USB flash disk integrates a disk storage technology, a flash memory technology and a universal serial bus technology. The port of the USB is connected with intelligent equipment such as a computer and the like and is a data input/output channel; the main control chip enables the computer to identify the USB flash disk as a movable disk, which is the brain of the USB flash disk; the Flash memory chip of the U disk saves data, which is different from the memory of the computer and cannot be lost even after power failure; the PCB backplane connects the components together and provides a platform for data processing.

Along with the convenience of network data transmission, the USB flash disk also reduces the use frequency, but in some specific time and places, the USB flash disk still needs to be used, but people often forget to carry the USB flash disk, because the USB flash disk has no other functions except for data storage accidents, and often forgets to carry the USB flash disk when not in use. With the advent of wireless headphones, particularly in recent years, TWS bluetooth headphones (True Wireless Stereo, true wireless headphones) are rapidly rising in the headphone market, and wireless headphones are also basically one hand on the basis that a mobile phone is basically one hand.

When people need to use the USB flash disk, people forget to carry the USB flash disk, and the earphone charging bin carried at any time has no storage function, so how to solve the problems is a problem to be solved urgently.
