Claim Text:
1. A method for manufacturing a panel for ventilation and noise reduction comprising: punching or cutting, according to a plurality of preset ventilation hole areas, a part of edges of every ventilation hole area on each of a left part and a right part of the panel to form a plurality of bendable parts; bending every formed bendable part along an uncut edge of every preset ventilation hole area to form ventilation holes, wherein every formed bendable part acts as a sound insulation board, wherein every sound insulation board is located in a propagation path of exhaust air from an interior of an electronic device to the ventilation holes such that the propagation path of the exhaust air is obstructed by one or more of the sound insulation boards and at least a part of the exhaust air is prevented from passing through the ventilation holes, wherein an amount of sound passing through the ventilation holes resulting from noise originating in the interior of the electronic device is reduced by the one or more of the sound insulation boards wherein every ventilation hole on the left part of the panel and every ventilation hole on the right part of the panel are located at positions that are staggered relative to each other; and bending the panel according to a preset shape so that the panel protrudes externally relative to the electronic device after the panel is installed on a ventilation port of the electronic device.
