Problems solved by technology
In traditional audio components or audio devices, such as players, amplifiers, speakers, microphones, earphones, cellular phones, sound cards in computers, wireless audio devices, television sets, or transmission cables, electronic signals are liable to external environment, such as radio frequency (RF), static electricity, or radiation in ambient air, therefore resulting in noise.
The electronic signals are also liable to the noise generated in the transmission cables or electronic components / circuits in the audio devices, therefore decreasing the quality of sound or even resulting in distortion.
As the electronic signals processed by the player and the power amplifier are outputted and sent to speakers via the transmission cables, the impedance, capacitance, and inductance phenomena of the transmission cables may degrade the electronic signals and cause phase mismatch between right and left channel.
Furthermore, the aforementioned external environment and the electronic components / circuits in the audio devices may also cause to attach a multitude of noises to the electronic signals.
However, such practice is costly and extravagant, and thus is generally not a plausible one.
Further, the problems still maintain while the noises generated by the aforementioned external environment and the electronic components / circuits in the audio devices could not be overcome by the specific cables.
In addition to the audio components and audio devices, the fields other than the audio, such as the process or transmission of electronic signals in video components or devices, possess similar problems to be conquered.

Embodiment Construction
[0014]The detailed description of the present invention will be discussed in the following embodiments, which are not intended to limit the scope of the present invention, but can be adapted for other applications.
[0015]The noise suppressor for electronic signals of the present invention primarily includes Aluminum Oxide (Al2O3) and other oxide or oxides in powder form. These powdered oxides are evenly mixed with a predetermined ratio between / among these oxides. The mixed oxides are then molded by a mold, and then are sintered or fired under a high temperature enough to transform the Aluminum Oxide (Al2O3) and other oxide(s) to ceramics. During the process, the physical characteristics, such as magnetism or frequency-related attributes of the oxides are altered. The resultant noise suppressor is capable of recovering the electronic signals through absorbing or suppressing noise, and reshaping the waveform or filtering waveform glitch of the electronic signals. Although the following...

Abstract
The present invention is directed to a noise suppressor for electronic signals. The noise suppressor at least includes Aluminum Oxide (Al2O3) that is sintered under high temperature, resulting in ceramic Aluminum Oxide (Al2O3) for effectively absorbing or suppressing noise, and reshaping the waveform or filtering waveform glitch of the electronic signals.
