Disclosed is an MP3 player comprising a housing provided with a circuit board, a display screen connected to the circuit board, and a rechargeable battery for supplying power to the circuit board. Screw hole columns used for fixing the circuit board are provided within the housing. Screw holes matching the screw hole columns are provided on the circuit board. The circuit board is fixed with screws within the housing. Because the circuit board is fixed with the screws within the housing and the screws are firmly fixed, the circuit board is prevented from swaying within the housing, thus ensuring normal operation of the MP3 player. |
