【detailed description】

An MP3 player includes a housing and a display screen fixed in the housing, the display screen of the housing is provided with a display avoidance hole smaller than the display screen; and the housing is disposed at the housing a transparent flap covering the outer surface of the outer surface and covering the display avoidance hole; the flap is fixed to the face shell with glue. The invention has a protective film on the display screen, which is equivalent to installing a protective film on the display screen, and the user or other objects will not directly touch the display screen, so there is no scratching or Broken the display.

The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in FIGS. 1 to 4, the MP3 player includes a housing having a circuit board 3, a display screen 5 and a battery 7 built therein, the housing including a bottom case 1 and a face case 2 opposite to the bottom case 1, a face case 2 and a bottom The case 1 is detachably fixed. A screw hole post 23 for fixing the circuit board 3 is provided in the face shell 2, and a screw hole is provided on the circuit board 3 in cooperation with the screw hole post 23. There are two screw holes 31, which are arranged on both sides of the circuit board 3. The corresponding screw hole posts 23 are also two, and the two screws can firmly fix the circuit board 3 in the face shell 2. The screw hole column 23 is provided with a limiting platform, and the circuit board 3 terminates at the limiting platform, and the diameter of the limiting platform is larger than the diameter of the screw hole. The screw hole post is inserted into the screw hole and then fixed by screws, so that the screw hole column has a limited position on the circuit board to prevent the circuit board from moving, and the arrangement can make the circuit board fixed more firmly.

One end of the circuit board 3 is arranged side by side with a charging interface 34 for charging the battery and an audio output hole 35 inserted into the earphone. One end of the face shell 3 is provided with a charging jack 25 and an earphone matched with the audio output hole 35 and the charging port 34. The jack 24 is fixed to the other end of the face shell 2, and the face shell 2 is provided with a display avoidance hole 21 smaller than the display screen 5.
