[0029] The embodiment of the present invention discloses a method for earphone noise reduction, which is applied to a mobile terminal, combining figure 1 As shown, the method includes:

[0030] Step 101: Acquire environmental noise signals.

[0031] The environmental noise signal is a sound signal in the environment outside the audio playback device composed of a mobile terminal and an earphone connected to the mobile terminal, and the environmental noise signal is an external sound that interferes with the audio transmitted from the mobile terminal to the earphone end Signal. For example, when listening to music, due to the different sealing effect of the earphones connected to the mobile terminal, the noise in the external environment will enter the human ear at the same time, causing the user to hear the music delivered to the human ear while hearing the noise in the external environment. noise. Therefore, it is necessary to acquire and process the external environmental...

[0043] The embodiment of the present invention discloses a method for earphone noise reduction, which is applied to a mobile terminal, combining figure 2 As shown, the method includes:

[0044] Step 201: If it is determined that the mobile terminal is in a state of starting audio signal transmission with the earphone, acquire an environmental noise signal.

[0045] Specifically, the method for earphone noise reduction requires that when the mobile terminal has detected that it is currently in the operating state of audio signal transmission with the earphone, it starts to perform the next noise cancellation operation process such as acquiring environmental noise signals, so as to ensure that the process is in progress. on the accuracy. Specifically, the user can also choose to enable or disable the application process of the active noise cancellation mode according to the actual application scenario.

[0046] The environmental noise signal is a sound signal in the environme...

[0077] This embodiment provides a mobile terminal, which can realize the details of the earphone noise reduction methods in the first embodiment and the second embodiment, and achieve the same effect. to combine image 3 , Figure 4As shown, the mobile terminal includes: a first acquiring module 301 , a first generating module 302 , a second acquiring module 303 , a second generating module 304 and a sending module 305 .

[0078] The first acquisition module 301 is configured to acquire environmental noise signals.

[0079] The first generating module 302 is configured to generate a first audio signal that is opposite in phase to the environmental noise signal based on the environmental noise signal acquired by the first acquiring module 301 .

[0080] The second obtaining module 303 is configured to obtain a second audio signal to be sent to the earphone connected to the mobile terminal.

[0081] The second generation module 304 is configured to superimpose the first audio...

Abstract

The invention provides a method for reducing noise of an earphone and a mobile terminal. The method includes the steps of obtaining ambient noise signals, generating first audio signals opposite in phase to the ambient noise signals based on the ambient noise signals, obtaining second audio signals which are about to be sent to the earphone connected with the mobile terminal, generating target audio signals by superposing the first audio signals with the second audio signals, and sending the target audio signals to the earphone for playing. No extra special hardware is needed to reach good noise reduction effect, and cost remains relatively low. Popularization is facilitated and user demands can be satisfied.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for noise reduction of an earphone and a mobile terminal. Background technique [0002] Listening to music with headphones has become a trend and trend, but in some public places with a lot of traffic, such as public transportation stations such as buses, subways, airports, or commercial streets, there is often a lot of noise, due to the sealing of some headphones The effect is not good, these larger background noises tend to enter the ears while listening to songs and affect the effect of listening to songs, so a headset that can reduce noise is needed. [0003] However, most of the current earphones and mobile devices do not support noise reduction, which requires specific equipment to achieve certain inconvenience; and those earphones and terminals that support noise reduction are achieved by adding additional microphones and Special noise cancellation chips a...
