An embodiment of the disclosure provides an electronic device including a power supply, an optical to electrical converter and a controller. The power supply outputs a first electric power. The optical to electrical converter receives an infrared light beam and converts the infrared light beam to a second electric power. The controller is coupled to the power supply and the optical to electrical converter. The controller operates in a first mode and a second mode. When the controller operates in the first mode, the controller is activated by the second electric power and after the controller is activated, the controller operates in the second mode and drives the power supply. Then, the controller receives the first electric power and stops receiving the first electric power for operation.

Electronic device and electronic system and operation methods thereof

An audio output device includes a housing, a speaker, a switching unit, a fixing component and a control unit. An opening is formed on the housing. The speaker is for outputting sound. The switching unit is installed inside the housing. The fixing component is fixed in the opening of the housing for triggering the switching unit so that the switching unit outputs a switching signal. The control unit is electrically connected to the switching unit and the speaker, and the control unit controls the speaker to output sound in a corresponding sound field as the control unit receives the switching signal.

A USB plug connector structure can use the same set of terminals to apply on different USB connector patterns, such as plate edge connector or wire edge connector, through the design of various soldering portions and base portions being positioned on the same plane. Furthermore, the common mode signals generated from first and second differential signal transmission conductor sets can be restrained by means of first and second grounding base portions of a grounding transmission conductor surrounding first and second differential signal transmission conduct sets. In addition, crosstalk interference generated from the first and second differential signal transmission conductor sets to a signal transmission conductor set can be similarly isolated through the first and second grounding base portions. Furthermore, a bended angle of each bended portion ranges from 120 to 150 degrees, thereby guide scattered radio frequency interference.

An application structure for an electric wave effect of transmission conductor solves a high frequency crosswalk problem through the following structures. The applicature structure includes at least one transmission conductor, and the application structure includes a first differential signal transmission conductor set, first signal transmission conductor set, second differential signal transmission conductor set, first ground transmission conductor, third differential signal transmission conductor set, second signal transmission conductor set, fourth differential signal transmission conductor set, first power source transmission conductor, second power transmission conductor and second ground transmission conductor. Whereby, the suppression of common mode signals, and the guiding-to-scatter suppression of radio wave interference (RFI), electromagnetic wave interference (EMI), crosstalk and electrostatic discharge (ESD) can be achieved between each two differential signal conductors through the first and second ground transmission conductors depending on the structure components mentioned above.

The USB female connector contains an insulating base and a shielding casing enclosing the insulating base. On the insulating base, there is mainly a ground terminal having a flat ground contact section at an end on the insulating base. From the ground contact section, the ground terminal is forked into ground extension sections. Through the forked ground extension sections, the crosstalk on the first, second, third, and fourth differential signal terminals by the first and second signal terminals is effectively resolved.

The USB female connector contains an insulating base and a shielding casing enclosing the insulating base. On the insulating base, there is mainly a ground terminal having a flat ground contact section at an end on the insulating base. From the ground contact section, the ground terminal is extended away from the insulating base and forked into a first ground extension section, a second ground extension section, and a third ground extension section. Through the forked first, second, and third ground extension sections, the high-frequency crosstalk problem is effectively resolved.
