Problems solved by technology
[0002] In daily life, people often use wireless communication to communicate, but when wireless communication is transmitted, noise interference often occurs, so that when the transmitted data is disturbed, the sound signal is confused, resulting in the inability to receive the transmitted data or the transmitted data. The data is not clear
When playing the transmitted data, due to noise interference, people cannot hear the voice information of the other party clearly. The existing noise reduction system is not perfect for noise processing, and there is still noise interference after processing.

Embodiment Construction
[0012] In order to make the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings:
[0013] The system has a signal acquisition unit 1. When noise interference occurs, the signal acquisition unit 1 collects the noise signal, and can collect relevant information such as the location of the noise, and then uses the data detection unit 2 to perform information detection on the signal, including detecting Signal amplitude and other related information. Then the system uses the shielding unit 3 to shield the noise signal so as not to interfere with other systems, and then uses the noise processing unit 4 for noise processing.
[0014] Further, the noise processing unit 4 uses an expander to perform noise processing, and when the data detection unit 2 detects the amplitude data value of the noise, the noise processing unit 4 uses an expander to perform noise reduction processing on the noise amplitude.

The invention discloses an expandor-based noise reduction system. The expandor-based noise reduction system is provided with a signal acquisition unit which is used for acquiring noise signals inside a computer, a data detection unit which is used for detecting related data information of the noise signals found by the signal acquisition unit, a shielding unit which receives the data information uploaded by the signal acquisition unit and shields noises, and a noise processing unit which processes the noises after receiving noise detection information of the data detection unit. With the expandor-based noise reduction system adopted, the noises can be eliminated, and people can receive transmitted sound signals with easiness. The expandor-based noise reduction system can be installed in the computer, such that noise interference in the computer can be eliminated.
Description
technical field [0001] The invention relates to a noise reduction system, in particular to an expander-based noise reduction system. Background technique [0002] In daily life, people often use wireless communication to communicate, but when wireless communication is transmitted, noise interference often occurs, so that when the transmitted data is disturbed, the sound signal is confused, resulting in the failure to receive the transmitted data or the transmitted data. The data is unclear. When playing the transmitted data, due to noise interference, people cannot hear the other party's voice information clearly. The noise reduction system in the prior art is not perfect for noise processing, and there is still noise interference after processing. Contents of the invention [0003] According to the problems existing in the prior art, the present invention discloses a noise reduction system based on an expander, which has: [0004] A signal acquisition unit, the signal a...
