Abstract: The main body includes a first surface and a second surface opposite to the first surface. The accommodating groove is located on the first surface, and the battery compartment is located on the second surface. The circuit board is adjacent to the battery compartment. A flexible circuit board is disposed on the display screen module. A hole is disposed in a groove bottom wall of the accommodating groove. The hole penetrates one end, at which the battery compartment is disposed, of the second surface. The battery is accommodated in the battery compartment. The enclosure covers the main body to enclose the battery compartment. The display screen module is accommodated in the accommodating groove. The flexible circuit board passes through the hole, winds from a side of the battery compartment to a surface, facing the enclosure, of the battery, and extends along the surface until connected to the circuit board.
