With the continuous progress of technology, the type of the commercially available fast development of wearable device, earphone also emerges one after another,
In i.e. include a kind of true wireless stereo headset (TWS earphone)；This TWS earphone outer covering body does not need wired connection, left and right 2
A earphone forms stereophonic sound system by bluetooth.The characteristics of TWS earphone is without external wire rod is worn TWS earphone for user and is provided
It is convenient；User can also wear TWS earphone in sleep procedure, it is not necessary to worry that sleep procedure winds earphone wire.But for
The problem of due to its battery capacity, decrease of noise functions can't be added in TWS earphone in TWS earphone on the market at present；If
Decrease of noise functions is added in TWS earphone, then the power consumption of TWS earphone can be improved when opening the decrease of noise functions, to reduce the continuation of the journey of TWS
Time.In this regard, propose a kind of earphone noise-reduction method in this implementation, add decrease of noise functions in smart bluetooth earphone, at the same into
In row noise reduction process, noise reduction strategies are adjusted by detecting and determining the sleep state of user, and according to the sleep state of user, from
And the noise reduction power consumption of earphone is saved, and then extend cruise duration.
Specifically, the smart bluetooth earphone of the present embodiment is illustrated by taking true wireless stereo headset (TWS earphone) as an example；
This TWS earphone outer covering body does not need wired connection, and two sub- earphones (left and right earphone) are formed stereo by way of bluetooth
System, and the TWS earphone in the present embodiment also has decrease of noise functions.The characteristics of due to TWS earphone without external wire rod, user can be with
TWS earphone is worn in sleep procedure, and starts decrease of noise functions, is helped so that the TWS earphone be made to enter noise reduction mode progress noise reduction
It sleeps.Entrance for the noise reduction mode, can be user touched in a manner of touching decrease of noise functions on TWS earphone outer covering by
Key, to trigger corresponding noise reduction instruction；When TWS earphone receives noise reduction instruction, it can be instructed and be entered according to the noise reduction
Noise reduction mode.The noise reduction mode can also be that user issues relevant speech-controlled information to TWS earphone in a manner of voice,
Such as user says " entering noise reduction mode " or other control keywords to the microphone of TWS earphone；When TWS earphone passes through wheat
When gram wind detects the control voice of " entering noise reduction mode " (or other control keywords), i.e., refer to it is believed that receiving noise reduction
It enables, and noise reduction mode is entered according to noise reduction instruction.In addition, the noise reduction mode can also be timing enter mode, such as with
Can sleep period () be arranged at 7 points such as daily at 23 points in evening to the next morning for TWS earphone in advance in family, and TWS earphone is being switched on
State-detection, will be automatically into noise reduction mode to when being currently at the sleep period.Certainly, in addition to the example above, TWS earphone is also
It can be and enter noise reduction mode in other ways.
In the present embodiment, TWS earphone is when entering noise reduction mode, it will passes through the microphone (audio collection of TWS earphone
Device) the current environmental audio signal of acquisition.It is worth noting that since TWS earphone is usually to be worn at the ear of user,
Therefore the collected environmental audio signal of microphone institute of TWS earphone, it is believed that it is the ambient sound that reflects user and can hear, and
The position of TWS earphone is also exactly to noise reduction position.Further, when being slept due to user, environmental noise is in a period of time
Inside can generally keep certain stability (too big variation will not occur), thus the acquisition of the environmental audio signal can be with
The mode of preset interval time carries out, such as acquisition in every 3 minutes is primary, to further decrease the power consumption of TWS earphone.It is acquiring
While environmental audio signal, TWS earphone will also detect the earphone status information of TWS earphone by sensor, namely determine ear
The use state of machine.Such as TWS earphone detects TWS in the acceleration of gravity of certain time period by gravity accelerometer
Value, to judge whether TWS earphone currently remains static according to the gravity acceleration value of this period.It is worth explanation
It is, because user, when wearing earphone, even if stationary be also required to breathe, and respiratory can also generate centainly earphone
Acceleration of gravity；Accordingly, when the variation of the acceleration of gravity of the earphone of certain time period is no more than certain threshold value, it is also contemplated that
It is currently at stationary state.Certainly in practice, TWS earphone can also detect ear by sensors such as vibrating sensor, gyroscopes
Machine status information.
Step S20 determines the sleep state of the user according to the earphone status information, and according to the sleep state
Determine corresponding noise reduction strategies；
In the present embodiment, TWS earphone is when obtaining earphone status information, as above-mentioned, since user constantly will in sleep
TWS earphone is worn at ear, therefore the earphone status information reacts the action status information of user to a certain extent, change and
Yan Zhi can determine the sleep state of user according to the earphone status information.For example, earphone status information is included in certain time period
The gravity acceleration value detected, and 3 acceleration of gravity difference sections are also previously provided in TWS earphone, it is denoted as 0 respectively≤
X < a, a≤x < b, b≤x, wherein x is the peak acceleration difference in the gravity acceleration value detected the period, and a, b are
One parameter preset, and 0 < a < b；As 0≤x < a, it is believed that user is currently at deep sleep, and mitigation is compared in breathing,
And do not have other movements；As a≤x < b, it is believed that user is currently at hypophypnosis state, and breathing tends to mitigate；And work as
When b≤x, it is believed that user not yet falls asleep, and amplitude of respiration is larger, it is also possible to turn or other movements are carried out, thus gravity accelerates
The amplitude of variation of angle value is larger.Certainly in practice, the acceleration of gravity difference section or the dormant determination of user can
To be arranged to other way；And it can also be adjusted accordingly according to the actual situation when according to other sensors.
In the present embodiment, when determining the sleep state of user, TWS earphone will be determined according to the sleep state of user and be corresponded to
Noise reduction strategies.Specifically, when user is in deep sleep, it is believed that user is not readily susceptible to the influence of noise, this
When can by noise reduction strategies towards slight noise reduction direction adjust；And when user is in hypophypnosis state or does not fall asleep,
It is believed that user is easier to the influence by noise, noise reduction strategies can be adjusted towards the direction of severe noise reduction at this time.Certainly, right
In the noise reduction strategies, the continuous dynamic adjustment in user's sleep procedure can be, for example, the noise reduction strategies may include silence
Strategy, general strategy, depth-size strategy, corresponding noise reduction depth (dynamics) is successively promoted namely noise reduction effect is successively promoted；?
In 24 points (0 points) to 1 point of period, TWS earphone determines that user is in hypophypnosis state according to earphone status information, then
TWS earphone can determine that current noise reduction strategies are general strategy；Within 1 point to 2 points of period, TWS earphone is according to earphone state
Information determines that user is in deep sleep, then TWS earphone can determine that current noise reduction strategies are silencing strategies；At 2 points to 3 points
Period in, TWS earphone determines that user is in hypophypnosis state according to earphone status information, then TWS earphone, which can determine, works as
Preceding noise reduction strategies are general strategy.
Step S30 generates corresponding noise reduction audio signal based on the noise reduction strategies and the environmental audio signal, and broadcasts
Put the noise reduction audio signal.
In the present embodiment, TWS earphone can be obtained when determining noise reduction strategies according in the noise reduction strategies and step S10
The environmental audio signal obtained generates corresponding noise reduction audio signal.For the noise reduction process of the noise reduction audio signal, pass through Mike
Then collected environmental audio signal is converted to frequency-region signal, then passes through frequency-region signal energy by elegance collection environmental audio signal
The distribution situation of amount finds the energy highest frequency range frequency range most deep as noise reduction；Filter parameter is arranged according to the frequency range in DSP,
Environmental audio signal is collected, by generating after filter process, signal amplitude and noise amplitude be of substantially equal, phase base again
This opposite noise reduction audio signal, and loudspeaker are driven according to the noise reduction audio signal, loudspeaker can offset big portion after making a sound
Divide noise.It is worth noting that the present embodiment when carrying out noise reduction, is not only to carry out noise reduction according to environmental audio signal, by root
Noise reduction is carried out according to noise reduction strategies, which is regarded as noise reduction depth, namely the depth to offset external noise (outer
Connect how many decibel have dropped in noise).Such as under general strategy, the external noise for needing to offset is 20 decibels, and if initial outside
Ambient sound is 30 decibels, then the external noise that user can hear after offsetting will be 10 decibels by noise reduction；It to be supported under depth-size strategy
30 decibels of the external noise to disappear, and if initial external environment sound is 35 decibels, the outside that user can hear after offsetting
Noise will be 5 decibels by noise reduction.
Further, in the present embodiment, when determining that user is in deep sleep according to earphone status information, due to
It is generally not readily susceptible to the influence of noise under deep sleep, can also directly exit noise reduction mode at this time, even voluntarily close
It closes, to reduce power consumption.Specifically, in step S20, when determining that user is in deep sleep according to earphone status information
When, noise reduction strategies can be determined as silencing strategies；When determining silencing strategies, TWS earphone will exit institute according to the silencing strategies
Noise reduction mode is stated, or is directly shut down according to the silencing strategies, to reduce power consumption.
In the present embodiment, smart bluetooth earphone acquires environmental audio signal when entering noise reduction mode, through microphone, and
The earphone status information of the smart bluetooth earphone is detected by sensor；The user is determined according to the earphone status information
Sleep state, and corresponding noise reduction strategies are determined according to the sleep state；Based on the noise reduction strategies and the ambient sound
Frequency signal generates corresponding noise reduction audio signal, and plays the noise reduction audio signal.In the above manner, the present embodiment is in intelligence
Decrease of noise functions can be added in bluetooth headset, while in carrying out noise reduction process, be determined indirectly by the status information of test earphone
The sleep state of user, and noise reduction strategies are determined according to the sleep state of user, it is carried out further according to noise reduction strategies and ambient sound
Noise reduction operation, to can also save the power consumption of earphone noise reduction while realizing noise reduction sleeping, extend cruise duration, favorably
In the usage experience for improving user.
