Abstract

The invention discloses an electronic device, which includes a fan, a flow guiding channel and a sound-absorbing structure, the guiding flow channel is used to guide the airflow generated by the fan, and the sound-absorbing structure is arranged on the first side wall of the guiding flow channel , the noise reduction structure has a cavity, a first layer and a second layer, the first layer has a plurality of first openings, the second layer has a plurality of second openings, the first layer and the second The layers are attached to each other and can be rotated relative to each other, and the relative rotation of the second layer and the first layer changes the relative corresponding positions of the plurality of second openings and the plurality of first openings, so that the sound-absorbing structure is selectively in the first position. A state and a second state, the size of the first ventilation structure formed in the first state is smaller than the size of the second ventilation structure in the second state. Elimination or reduction of noise at different frequencies is thereby achieved.

Description

technical field [0001] The invention describes an electronic device, especially an electronic device with low noise. Background technique [0002] The technology of DLP electronic device is a kind of all-digital reflective projection technology. Its characteristics are digital advantages firstly: the adoption of digital technology improves the image gray level, image noise disappears, the picture quality is stable, and the digital image is very accurate; secondly, reflection Advantage. The DLP electronic device has high definition, uniform picture, sharp, delicate, natural and lifelike colors, and the three-chip computer can achieve high brightness, and can zoom at will, which is very convenient to adjust. [0003] The working principle of the DLP electronic device is to filter the light beam emitted by the light source into three colors of red, green and blue through the rotating color wheel module, and then transmit it to the display component to convert it into an image ...
