An electronic device capable of controlling light-emitting diode (LED) bright is provided. The electronic device includes a signal producing unit for producing an operation signal; a Micro Control Unit (MCU) configured for outputting a normal brightness control signal according to the operation signal, and outputting a ultra brightness control signal according to the operation signal when an actual idle time of the electronic device reaches or exceeds a predetermined idle time; a pulse current control unit for controlling an output current according to the normal brightness control and the ultra brightness control signal; and a LED illuminator array for emitting light based on the output current. The MCU terminates the output of the ultra brightness control signal when an actual time of outputting the ultra brightness control signals reaches a predetermined time, and then the LED illuminator array resumes its normally bright. A control method is also provided.

A shake responsive media player is provided. The media player comprises a vibration switch that changes its state between an electrically open state and an electrically closed state during the media player is shaken. The media player also comprises a storage unit, a motion state determining unit, a media file determining unit, and a processing unit. The storage unit stores a plurality of media files and a table that defines relationships between shaking levels and the sampling rates of the at least one group of media files. The motion state determining unit determines a duration of the shaking of the media player and the times of state changing of the vibration switch according to signals from the vibration switch and determines a shaking level according to the duration of the shaking of the media player and the times of state changing of the vibration switch.

摘要:
An electronic device includes a front frame, a back cover, a support stand rotatably connected to the back cover, a display panel and a circuit board. The display panel and the circuit board are fixed between the front frame and the back cover. The circuit board includes a first contact and a number of second contacts. The second contacts surround the first contact. The support includes a central shaft and a third contact. The central shaft is electrically connected to the first contact. The third contact rotates with the rotation of the central shaft to contact each of the second contacts. The circuit board includes a circuit and a processor. The electric circuit generates different signals when the first contact is connected different second contacts. The processor adjusts an orientation of display content on the display panel to rotate based on the signal.
