The invention discloses a reflector cup sputtering control main case with a noise elimination function. The case comprises a case body, a power supply interface, a heat dissipation opening, a noise elimination device, I/O interfaces, serial ports, an air inlet, headphone jacks, machine bases, a noise elimination sponge panel, a noise elimination interlayer, a fixed steel plate, set screws, a Sono noise eliminator, a noise elimination suction cup, a connecting rack and a noise elimination computer core. The noise elimination device is arranged on one side of the computer case, the noise elimination sponge panel is arranged on one side of the noise elimination device, a sponge is made of an EVA material is resistant to high temperature and can filter and absorb part of noise generated by the case, the Sono eliminator is arranged on the interlayer of the elimination device, the principle applies a so-called ANC active noise reduction technology built by BOSE, when the case works to generate the noise, the eliminator can generate a sound opposite to the noise for superposition so as to eliminate the rest noise obtained after sponge absorption, the case can work more quietly, use is more comfortable, the computer case is convenient to operate, stable and firm, and all components are flexible in connection.
