Abstract

An electronic device is provided. The electronic device includes an input/output port, a rechargeable battery, a charging device, and an audio receiving and playing device. The rechargeable battery is charged to provide a battery voltage in response to switching between a first charging power source and a second charging power source. The charging device converts the DC input power source into the first charging power source or the second charging power source to charge the rechargeable battery according to the detection signal associated with the battery voltage. A charging speed of the first charging power source for charging the rechargeable battery is greater than a charging speed of the second charging power source for charging the rechargeable battery. The audio receiving and playing device performs at least one of a playing operation and a receiving operation of an audio signal by operating under the battery voltage.
