In a method for permitting change of an electronic card without powering off and a communications device employing the method, the communications device includes a control module, a card connector for receiving the electronic card, and a trigger module. The method includes: when the communications device is in an on state, triggering the trigger module to generate a trigger signal to the control module; enabling the control module to determine a card insertion mode if it is detected that a state of electrical connection of the card connector with an electronic card changes from a disconnected state to a connected state after receipt of the trigger signal; and enabling the control module for supplying power to the electronic card inserted into the card connector upon determining the card insertion mode.

Method for permitting change of an electronic card without powering off and communications device employing the method

An electronic device includes a first circuit board having a first audio source and a first reference grounding end, a second circuit board having a second audio source and a second reference grounding end, a flexible board cable, a grounding wiring, a selection unit, and a receiver. The flexible board cable couples the first audio source to the second circuit board. The grounding wiring couples the first grounding end to the second circuit board. The selection unit is used for selecting one from the first and second audio sources to output and selecting one from the first and second reference grounding ends to output. An input end of the receiver is controlled by the selection unit to be connected to the first or second audio sources, and a grounding end of the receiver is controlled by the selection unit to be connected to the first or second reference grounding ends.
