A portable miniature audio player comprising a cylindrical body (1) sized to fit the hand, a speaker (3) fixed at an extremity of the body (1), a battery (4) fixed with a battery compartment (8) within the body, a main circuit board (9) provided with a TF card interface and a USB interface, and a button circuit board (5) for controlling the main circuit board (9). The button circuit board (5) is fixed at an extremity of the battery compartment (8). Protruding plates (86) that protrude outwards are provided at either side at the bottom of the battery compartment (8). Two strip-shaped protrusions (102) parallel each other and mated with the protruding plates (86) are provided at either side of the body (1). The battery compartment (8) is engaged in the strip-shaped protrusions (102) of the body (1). The main circuit board (9) is configured to fit the battery compartment (8) and is fixed with screws at the bottom of the battery compartment (8). Because the main circuit board (9) is fixed with the screws at the bottom of the battery compartment (8) and the battery compartment (8) is engaged in the body (1), the main circuit board (9) is firmly fixed. |
