Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0040] In the prior art, the mobile terminal cannot automatically turn on or off the noise reduction device / function of the mobile phone according to the specific conditions of the caller's environment, which affects the call quality. In a specific embodiment of the present invention, by judging the environment (noisy or quiet) of the caller, the noise reduction function of the mobile terminal is turned on / off adaptively, so that the call quality can be effectively ...

The embodiment of the invention discloses a mobile terminal noise processing method and a mobile terminal. The method comprises the following steps of: acquiring a call target voice signal and an environmental noise signal in the call process of the mobile terminal; acquiring a signal-noise parameter according to the call target voice signal and the environmental noise signal; comparing the signal-noise parameter with a preset parameter threshold value, and readjusting the de-noising function state according to the comparison result and the current de-noising function closing state, wherein the readjustment of the de-noising function state comprises starting the de-noising function when the current de-noising function is shut down, shutting down the de-noising function when the current de-noising function is started or keeping the current de-noising function state; and performing de-noising according to the readjusted de-noising function state. By adopting the embodiment of the invention, the method can realize adaptive starting and shutdown of the de-noising function and improve the call quality.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile terminal noise processing method and a mobile terminal. Background technique [0002] With the continuous development and popularization of mobile communications, mobile terminals (eg, mobile phones) play an increasingly important role in people's daily life. At the same time, users of mobile terminals have higher and higher demands on the functions and performances of the mobile terminals. For example, users want to improve the sound quality of calls; for this reason, a mobile phone noise reduction technology has emerged, which can improve the sound quality of calls. [0003] However, the inventor found in the research process that the existing noise reduction devices / functions all need to be manually turned on and off. When the user walks from a very noisy environment to a quiet environment during a call, if the user If the noise reduction device was turned on bef...
