Abstract: An electronic device including a main body, a heat dissipation fan and at least one block is provided. The main body has a side shell and a bottom shell. The side shell has a first air inlet and a first air outlet. The heat dissipation fan is disposed in the main body and has at least one second air inlet and at least one second air outlet. The second air outlet is aligned to the first air outlet. The block is disposed in the main body to form a channel with the bottom shell and the dissipation fan. The channel is extended between the second air inlet and the first air inlet, so as to guide airflow to pass through the first air inlet and the second air inlet sequentially and enter the heat dissipation fan.

Abstract: A method of triggering applications on smart phone devices is provided, and the method triggers the smart device in particular way to activate at least one application based on a screen brightness variation of the smart device, wherein the triggering method may be performed by clicking, shaking or a distance sensing.

Abstract: An electronic device including an audio module, a monitoring module and a fan is provided. The audio module generates an audio signal and an audio parameter according to audio data, and transmits the audio signal to a play device. Furthermore, the monitoring module determines a speed of fan rotation base on the type of the play device, the audio parameter and a sensed temperature. Then, a rotation speed of the fan is adjusted according to the determined speed of fan rotation.

Abstract: An electronic apparatus includes a casing, a separation structure, a fan, a first heat generating element and a heat conducting module. The casing has an air inlet and an air outlet. An inner portion of the casing includes first and second areas connected to the air inlet and the air outlet respectively. The separation structure is disposed at a border between the first and the second areas to separate the first and second areas. The fan is disposed in the first area adjacent to the air inlet and adapted to provide a heat dissipation airflow. The heat dissipation airflow flows through the air inlet, the first area, the second area and the air outlet sequentially. The first heat generating element is disposed in the second area. The heat conducting module is connected between the fan and the first heat generating element.
