Abstract

The invention discloses a mobile terminal comprising a first short-range wireless communication module used for receiving an environment noise signal sent by a noise detection device via a second short-range wireless communication module; a denoising signal generating module used for generating an audio denoising signal according to the environmental noise signal; and an audio playing module used for playing the audio denoising signal. The invention also discloses a denoising device comprising the noise detection device and the mobile terminal, wherein the noise audio detection device comprises an audio sensing module used for detecting environmental noise and transmitting the environmental noise to the second short-range wireless communication module; and the second short-range wireless communication module is used for sending the environmental noise signal to the mobile terminal. The invention also discloses a corresponding denoising method. By using the scheme of the mobile terminal, the denoising device and the denoising method thereof provided by the invention, noise close to the terminal can be reduced or counteracted, and the effect of denoising actively is achieved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a mobile terminal, a noise reduction device and a noise reduction method thereof. Background technique [0002] There are usually three noise reduction measures used to reduce noise, namely: noise reduction at the sound source, noise reduction during transmission, and noise reduction at the human ear. These measures are actually passive. In order to actively eliminate noise, the technology of "active noise cancellation", that is, ANC (Active Noise Cancellation) active noise cancellation, has emerged. Its principle is: since all sounds are composed of a certain frequency spectrum, if a The frequency spectrum of the sound is exactly the same as the noise to be eliminated, but the phase is just opposite (180° difference), and the noise can be neutralized, or even completely canceled, so as to achieve the effect of noise reduction. The key to ANC is how to get a sound that cancels ou...
