摘要： An electronic device with redundant fan control function includes a first fan, a first control module, a first power supply, a first switch unit, a second fan, a second control module, a second power supply, and a second switch unit. When the first power supply stops working, the second power supply powers the first fan and the second fan, and the first power supply sends a control signal to turn on the first switch unit to allow a group of control information output by the second control module to control the first fan. Therefore, the first fan and the second fan can work normally to dissipate heat from the electronic device.

摘要： An exemplary audio signal transmission circuit includes a codec to provide analog and digital audio signals; an amplifier connected to the codec to receive the analog audio signals; a control circuit connected to the codec to receive the digital audio signals and connected to the amplifier to selectively turn off the amplifier; a front audio port connected to the amplifier to receive amplified analog audio signals generated by the amplifier; and a rear audio port connected to the amplifier and the control circuit to selectively receive the amplified analog audio signals or the digital audio signals. The control circuit and the front audio port are turned off when the rear audio port is connected to an analog system, and the amplifier and the front audio port are turned off when the rear audio port is connected to a digital system.
