An electronic device includes a casing, a driven component, a magnetic component and an electromagnetic component. The casing has an outer surface, an inner surface, and an accommodating groove penetrating through the outer surface and the inner surface. The driven component is movably disposed in the accommodating groove. The magnetic component is connected to the driven component. The electromagnetic component is aligned with the magnetic component, and the magnetic component and the electromagnetic component are located at the same side of the inner surface. When the electromagnetic component isn't powered, the magnetic component and the electromagnetic component are attracted to each other, and the driven component is positioned at a first position. When the electromagnetic component is powered, the magnetic component and the electromagnetic component are repulsed to each other so as to drive the driven component to move from the first position to the second position.

A multimedia playing system is provided. A portable electronic device includes a first dock port, a second dock port, a power module, an audio processor and a controller. When a first single-ear wireless earphone connects with the first dock port, the power module charges the first single-ear wireless earphone via the first dock port. When a second single-ear wireless earphone connects with the second dock port, the power module charges the second single-ear wireless earphone via the second dock port. The audio processor provides a left sound channel signal and a right sound channel signal. When the first single-ear wireless earphone separates from the first dock port, the controller provides one of the left sound channel signal and the right sound channel signal to the first single-ear wireless earphone according to a relative position between the first dock port and a user.
