Abstract
A power supply system includes an electronic device configured to output from an external audio output terminal a power-supply signal according to a target value for supply voltage when power is supplied to an external device and a cable with a rectifier circuit that rectifies the power-supply signal and generates the supply voltage.
Claims19
A power supply system comprising:
- an electronic device configured to output from an external audio output terminal a power-supply signal according to a target value for a supply voltage when power is supplied to an external device;
- and
- a cable including a rectifier circuit configured to rectify the power-supply signal and generate the supply voltage.
An electronic device comprising:
- an external audio output terminal;
- and
- a controller configured and programmed to control switching between an external audio output mode which outputs an audio signal from the external audio output terminal and an external power supply mode which outputs a power-supply signal from the external audio output terminal.
A cable comprising:
- a first connector that is configured to be connected to or disconnected from an external audio output terminal of an electronic device which defines a power-supplying side;
- a second connector that is configured to be connected to or disconnected from a power supply terminal of an external device which defines a power-receiving side;
- and
- a rectifier circuit configured to generate a supply voltage to the external device by rectifying a power-supply signal that is output from the external audio output terminal of the electronic device.
A non-transitory computer-readable medium including a program for performing, when the program runs on a controller of an electronic device including an external audio output terminal in order to supply power from the electronic device to an external device over a cable with a rectifier circuit, a method comprising the steps of:
- switching between an external audio output mode and an external power supply mode;
- controlling signal output from the external audio output terminal such that an audio signal is output according to audio data when in the external audio output mode;
- and
- controlling signal output from the external audio output terminal such that a power-supply signal is output according to a target value for supply voltage to the external device when in the external power supply mode.
