STRUCTURE AND A METHOD FOR SUPPRESSING AUDIO NOISE OF ELECTRONIC EQUIPMENT

摘要

A structure and a method for suppressing audio noise of electronic equipment are carried out by utilizing an audio noise suppressing structure to cover a periphery or a surface of the electronic equipment or circuits thereof. The audio noise suppressing structure mainly comprises zirconia and at least one oxide serving as a stabilizer. The zirconia and the oxide are evenly mixed and sintered with a high temperature to form an electrically conductive ceramic body. In use, because the audio noise suppressing structure is disposed on a periphery or a surface of the electronic equipment or the audio circuits thereof, the electrification of the electronic equipment or audio circuits create shunt conductance, far infrared radiations and a resonance effect to reduce the thermal accumulation. Thus, the accumulated heat possibly caused by working the electronic equipment is reduced or fully dispersed, thereby attaining a decrease in the noise.
