Abstract

The invention discloses an active noise reduction system of a communication device and a noise reduction processing method of the same. The active noise reduction system comprises an identifiable signal detector, a noise detector and a signal processor, wherein the identifiable signal detector is used for detecting identifiable signals and transmitting the identifiable signals to the signal processor; the noise detector is used for detecting noise signals around the communication device and transmitting the noise signals to the signal processor; the signal processor is used for noise reduction processing of the identifiable signals according to the noise signals to obtain noise reduction processing signals; and the signal processor is respectively connected with the identifiable signal detector and the noise detector. The same noise signals doped in the identifiable signals can be neutralized or counterbalanced according to the detected noise signals so as to obtain the noise reduction processing signals. Therefore, the communication quality of audio signals can be improved, and the fidelity, the clarity and the identifiability of the audio signals can also be improved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to an active noise reduction system of communication equipment and a noise reduction processing method thereof. Background technique [0002] When people use communication equipment for audio signal transmission, what they need is an identifiable signal. The identifiable signal refers to the clear signal that people originally need to transmit to the receiver, but when people use the identifiable signal detector (in the communication system A component that can be used to detect an identifiable signal that the user needs to transmit, and convert the identifiable signal into an electronic signal, so that the electronic signal can be transmitted by the communication system) While detecting the identifiable signal, the identifiable Discrimination signal detectors can also detect and transmit noise signals around communication equipment (noise signals refer to unnecessary electric...
