An electronic device with a power management mechanism and a power management method thereof are disclosed. The electronic device includes a multi-core processor and a temperature sensor. The multi-core processor has a plurality of processor cores. The temperature sensor is coupled to the multi-core processor. The temperature sensor detects the temperature of the multi-core processor and determines whether the electronic device enters an underclocking mode from a performance priority mode according to the detected temperature. When the temperature of the multi-core processor is greater than a first temperature threshold, the multi-core processor controls the electronic device to enter a first underclocking mode and dynamically adjusts an enabled core number. When the temperature of the multi-core processor is greater than a second temperature threshold, the multi-core processor controls the electronic device to enter a second underclocking mode. The first temperature threshold is smaller than the second temperature threshold.

Electronic device with power management mechanism and power management method thereof

A method for controlling rotation speed is suitable for an electronic device having a vibrating fan module. The vibrating fan module can generate vibration and output airflow simultaneously. The method for controlling rotation speed includes the following steps. Whether a vibration signal transmitted by the electronic device is received is determined. When the vibration signal is received, a rotation speed of the vibrating fan module is adjusted to a vibration rotation speed. A temperature of the electronic device is sensed. Whether the temperature of the electronic device is greater than or equal to a first preset temperature is determined. When the temperature of the electronic device is greater than or equal to the first preset temperature, the rotation speed of the vibrating fan module is adjusted to a first rotation speed according to the temperature of the electronic device. The first rotation speed is less than the vibration rotation speed.

An electronic apparatus and a protective cover for a mobile device are disclosed. The protective cover is removably attached on an outer surface of a mobile device. The protective cover comprises an outer protective layer, a thermo-conductive layer and a thermoelectric material layer. The thermo-conductive layer is attached on the outer surface of the mobile device. The thermoelectric material layer has a first side adjacent to the thermo-conductive layer and a second side adjacent to the outer protective layer. The thermoelectric material layer generates a current according to a temperature difference between the first side and the second side.
