Detailed Description

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention.

Referring to the drawings, the utility model provides an earphone charging mobile phone shell, including cell-phone shell main part and earphone storehouse, the formula connection earphone storehouse is inhaled and earphone charging is given to the magnetism in the cell-phone shell main part, and the cell-phone shell main part embeds there is the ultra-thin battery who charges for the earphone storehouse. The ultra-thin battery is charged through NFC, and the ultra-thin battery is charged through NFC in a wireless mode, namely, the ultra-thin battery is charged through coil induction. The formula is connected through magnetism between earphone storehouse and the cell-phone shell main part, and the formula adsorbs the back through magnetism, and ultra-thin battery can supply power for the earphone storehouse, as shown in the drawing, the earphone storehouse is fixed through magnetism type of inhaling through fixing the magnet in the cell-phone shell.
