摘要： An electronic apparatus includes a main body, at least one fan in the main body, an audio receiving module on the main body, and a control module electrically connected to the audio receiving module and the fan. If the audio receiving module receives an activation command, the control module records an instant value of a rotation speed of the fan and controls the rotation speed to be decreased. After the rotation speed is reduced, if the audio receiving module receives a voice command within a predetermined time period, the electronic apparatus executes the voice command, and the control module controls the rotation speed to be returned to the instant value; if the audio receiving module does not receive the voice command within the predetermined time period, the control module controls the rotation speed to be returned to the instant value.

摘要： A projection apparatus includes an illumination system; an optical engine module; a lens module; and a heat-dissipation module. The illumination system includes a light source, and is configured to provide an illumination light beam. The optical engine module includes a light valve. The light valve is disposed on a transmission path of the illumination light beam, and configured to convert the illumination light beam into an image light beam. The lens module is disposed on a transmission path of the image light beam, and configured to project the image light beam out of the projection apparatus. The lens module has an optical axis. The lens module is adapted to move between a first position and a second position along the optical axis. The heat-dissipation module includes a heat dissipating device, a first liquid-cooling plate, a second liquid-cooling plate, and a plurality of pipes. The first liquid-cooling plate is connected to the light source. The second liquid-cooling plate is connected to the light valve. The heat dissipating device, the first liquid-cooling plate, and the second liquid-cooling plate are connected to each other via the plurality of pipes and form a loop to circularly dissipate heat from the light source and the light valve. When the lens module moves, the light source, the first liquid-cooling plate, the light valve, and the second liquid-cooling plate move together with the lens module.

摘要： A phosphor wheel includes a rotating disk and a wavelength converting layer. The rotating disk has a first surface and a second surface opposite to the first surface, in which the first surface forms a coating region and a non-coating region. The wavelength converting layer is formed on the coating region of the first surface for converting a light wavelength of a light beam. In addition, an embodiment of the invention discloses a projection device having the phosphor wheel. When the rotating disk of the phosphor wheel rotates, the recess portion may disturb the air around the phosphor wheel such that the temperature of the wavelength converting layer may be effectively decreased. Simultaneously, the rotating disk has a stable dynamic balance and the rotating disk has a larger heat dissipating region because the recess portion is disposed on the rotating disk.
