Embodiment 1

[0023] figure 1 It is an implementation flow chart of the earphone noise reduction method provided by the embodiment of the present invention, and is described in detail as follows:

[0024] In step S101, use the earphone microphone to collect the noise signal of the environment;

Embodiment approach

[0025] Among them, using the earphone microphone to collect the noise signal of the environment, there are two implementation methods, which are described in detail as follows:

[0026] The first implementation mode:

[0027] Every preset detection interval, the earphone microphone is used to collect the noise signal of the environment.

[0028] It should be noted that since the environmental noise signal usually does not change much within a period of time, the detection of the environmental noise signal at a preset detection interval can further save the power consumption of the earphone .

[0029] The second implementation mode:

[0030] When the distance from the geographic location where the noise signal of the environment was collected last time is not less than the preset distance, the noise signal of the environment is collected by using the earphone microphone.

[0031] It should be noted that since the distance between the earphone and the geographical location wh...

Embodiment 2

[0044] figure 2 It is an implementation flowchart of the earphone noise reduction method S102 provided by the embodiment of the present invention, and is described in detail as follows:

[0045] In step S201, input part of the noise signal into the sampling channel;

[0046] In step S202, in the sampling channel, perform analog-to-digital conversion on part of the noise signal to generate a noise value of the noise signal;

[0047] In step S203, the noise value corresponding to the noise signal is sent to the connected terminal.

[0048] In the embodiment of the present invention, the noise value corresponding to the noise signal is sent to the connected terminal, so that the receiving terminal can turn on or off the noise reduction function according to the judgment result generated by the noise signal.

Abstract

The invention is applicable to the technical field of wearable equipment, and provides a headset noise reduction method and device. The headset noise reduction method includes the steps that noise signals of the environment are collected through a headset microphone; noise signals or noise values corresponding to the noise signals are sent to a connected terminal; a judgment result returned by the terminal is received, and a noise reduction function is started or stopped according to the judgment result. The headset noise reduction method and device resolve the problems in the prior art that a key or shifting switch for adjusting noise reduction needs to be arranged on a headset, high integration of the headset is affected, and the noise reduction function can not be started or stopped in time. The headset noise reduction method and device have the advantages that on one hand, a manufacturer does not need to arrange the key or shifting switch for adjusting noise reduction on the headset; on the other hand, automatic noise reduction is realized, the noise reduction function is started or closed in time on the premise of not needing the key or shifting switch on the headset, and therefore the integration degree and endurance of the headset are improved.

Description

technical field [0001] The invention belongs to the technical field of wearable devices, and in particular relates to an earphone noise reduction method and device. Background technique [0002] Noise pollution is one of the four major pollutions recognized internationally. With the development of urbanization and technological progress, noise pollution has become more and more serious. When the user plays audio through an external earphone connected to the terminal, the noise reduction method of the earphone can be used to reduce the noise signal of the environment and protect the user's hearing. [0003] There are two ways to implement the noise reduction method of earphones currently used. The first way is to physically isolate the noise through the earphones so that it cannot enter the human ear; Phase inversion and superposition cancel out the noise entering the earphones, making it impossible for the human ear to perceive. [0004] However, the existing earphone nois...
