Based on the hardware architecture of the earphone control device/earphone, the embodiment of the earphone control method is provided.
Referring to fig. 2, fig. 2 is a first embodiment of the headphone control method according to the present invention, the headphone control method including the steps of:
in step S10, the ambient sound signal detected by the ambient microphone is acquired at regular time.
Specifically, the environment microphone is used for detecting an environment sound signal and acquiring the environment sound signal of the environment microphone at regular time. As shown in fig. 3, the environment microphones may be disposed at the outer side of the earphone, for example, at a and/or b, and the number of the environment microphones may be one or more.
After the ambient sound signal is acquired, the ambient sound signal is converted into a digital signal, and the signal intensity of the ambient sound signal is determined according to the digital signal. As shown in fig. 4, the ambient sound signal collected by the microphone is converted into a digital signal by an audio encoder in the earphone, and the digital signal is subjected to signal processing by the digital signal processor to obtain the signal intensity of the ambient sound signal. The bluetooth Integrated Circuit, the audio encoder and the digital signal processor are connected with each other through an Inter-Integrated Circuit (I2C) bus by a Pulse Code Modulation (PCM) between the bluetooth Integrated Circuit and the audio encoder and the digital signal processor.
In step S20, the intensity difference between the signal intensity of the currently detected ambient sound signal and the signal intensity of the last detected ambient sound signal is acquired.
Specifically, the currently detected ambient sound signal and the last detected ambient sound signal are ambient sound signals at adjacent detection time points, and the intensity difference of the signal intensity of the ambient sound signals at the adjacent detection time points is determined. The difference value obtained by subtracting the currently detected ambient sound signal from the last detected ambient sound signal is the intensity difference. The intensity difference may be an absolute value. Or when the signal intensity of the currently detected environmental sound signal is greater than the last detected environmental sound signal, the intensity difference is a negative value, and when the signal intensity of the currently detected environmental sound signal is less than the last detected environmental sound signal, the intensity difference is a positive value.
And step S30, when the intensity difference is larger than a preset threshold value, carrying out noise reduction operation on the earphone according to the environment sound signal.
Specifically, when the intensity difference is an absolute value, when the intensity difference is greater than a preset threshold value, the signal intensity of the environment sound signal is greatly changed, and the environment sound signal can be divided into two cases, wherein one case is that the currently detected environment sound signal is smaller than the last detected environment sound signal, and the earphone is covered by a hand in a noisy environment. Exemplarily, comparing the currently detected signal strength with the last detected signal strength; and when the intensity difference is larger than a preset threshold value, carrying out noise reduction operation on the earphone according to the environmental sound signal. The other situation is that the currently detected environment sound signal is larger than the last detected environment sound signal, which indicates that the external environment becomes noisier, and when the intensity difference is larger than the preset threshold value, the noise reduction operation is performed on the earphone according to the environment sound signal.
When the intensity value is not an absolute value, when the intensity difference is greater than a preset threshold value, the intensity value is a positive value, the signal intensity of the currently detected environment sound signal is smaller than the last detected environment sound signal, and when the intensity difference is greater than the preset threshold value, noise reduction operation is performed on the earphone according to the environment sound signal.
In the technical scheme of this embodiment, an ambient sound signal of an ambient microphone is acquired at regular time, an intensity difference between a currently detected signal intensity and a last detected signal intensity is calculated, and when the intensity difference is greater than a preset threshold value, a noise reduction operation is performed on the headset according to the ambient sound signal. The judgment of the environmental microphone on the sound signal is used for reducing the noise of the earphone, and compared with the condition that whether the noise of the earphone is reduced or not is judged by using a sensor, the cost of the earphone is reduced.
Referring to fig. 5, fig. 5 is a second embodiment of the earphone control method according to the present invention, and based on the first embodiment, before the step S10, the method further includes:
step S40, acquiring the sound state of the current environment of the earphone;
and step S50, when the sound state is a noisy state, executing the step of regularly acquiring the environmental sound signal detected by the environmental microphone.
Specifically, the environmental sound signals detected by the environmental microphone are acquired at regular time, and the sound state of the current environment is determined according to the signal intensity of the environmental sound signals. And if the signal intensity of the environment sound signal is less than or equal to the preset intensity, determining that the sound state is a quiet state. After the sound state is determined to be the noisy state, the signal strength of the ambient sound signal of the microphone is acquired at regular time.
In the technical scheme of this embodiment, whether the environment is in noisy environment has been confirmed according to sound state, if, then regularly acquires the environment sound signal of environment microphone, has avoided under the environment that need not fall the noise promptly in the noisy environment of non-, and the earphone falls the circumstances of making an uproar according to environment sound signal, has improved the earphone and has fallen the accuracy of making an uproar according to environment sound signal.
Referring to fig. 6, fig. 6 is a third embodiment of the earphone control method according to the present invention, and based on the first or second embodiment, the step S30 includes:
step S31, when the intensity difference is larger than a preset threshold value, acquiring a proximity signal detected by a proximity sensor in the earphone;
and step S32, when the approach signal meets the approach condition, carrying out noise reduction operation on the earphone according to the environment sound signal.
Specifically, when the intensity difference is greater than a preset threshold, a proximity signal detected by a proximity sensor in the headset is acquired. The proximity sensor can be a light sensor, a proximity signal of the light sensor is an optical signal, and when the intensity of the optical signal is smaller than a preset threshold value, the proximity signal is determined to meet a proximity condition. The proximity sensor may be a touch sensor, a proximity signal of the touch sensor is a physical touch or a pressure value applied on the earphone, and when the physical touch exists or the pressure value on the earphone is greater than a preset threshold, it is determined that the proximity signal satisfies a proximity condition. The proximity sensor can also be a radar sensor, the proximity signal of the radar sensor is a distance, and when the distance is smaller than a preset threshold value, the proximity signal is determined to meet the proximity condition. And when the approach signal meets the preset condition, carrying out noise reduction operation on the earphone according to the environment sound signal.
In the technical scheme of this embodiment, when the intensity difference is greater than the preset threshold, the approach signal detected by the approach sensor in the earphone is acquired for further judgment of the hand covering action of the user, and when the approach signal meets the approach condition, the noise of the earphone is reduced. The detection of the proximity sensor is increased, and the noise reduction accuracy of the earphone according to the environmental sound signal is improved.
Referring to fig. 7, fig. 7 is a fourth embodiment of the headphone control method according to the present invention, and based on any one of the first or third embodiments, after step S10, the method further includes:
step S60, detecting residual noise in the ear canal microphone;
step S70, when the signal strength of the currently detected ambient sound signal is less than the signal strength of the last detected ambient sound signal and the signal strength of the currently detected ambient sound signal is greater than the signal strength of the residual noise, performing the step of acquiring the strength difference between the signal strength of the currently detected ambient sound signal and the signal strength of the last detected ambient sound signal.
In particular, as shown in fig. 3, an ear canal microphone may be provided at an ear plug, i.e. c, of the earphone for sound signal detection of the ear canal of the earphone. After the ear canal microphone is worn, sound signals in the ear canal microphone are obtained, the sound signals may include audio signals played by the earphone, and the audio signals played by the earphone need to be removed from the sound signals, so that residual noise in the detection environment of the ear canal microphone is obtained. When the signal intensity of the currently detected environmental sound signal is smaller than the signal intensity of the last detected environmental sound signal and the signal intensity of the currently detected environmental sound signal is greater than the signal intensity of the residual noise, it indicates that the current environment is still a noisy environment, and the user has worn the earphone, and calculates the intensity difference between the currently detected signal intensity and the last detected signal intensity.
In the technical scheme of this embodiment, the detection of the residual noise in the ear microphone is added, and if the signal intensity of the currently detected ambient sound signal is equal to the signal intensity of the residual noise, it indicates that the user does not wear the earphone, and at this time, the earphone does not need to be controlled to perform noise reduction. If the signal intensity of the currently detected environmental sound signal is smaller than the signal intensity of the residual noise, the user is indicated to wear the earphone, and whether the noise reduction operation is performed on the earphone is determined according to the signal intensity of the environmental sound signal, so that the noise reduction accuracy of the earphone is improved.
Referring to fig. 8, fig. 8 is a fifth embodiment of the headphone control method according to the present invention, where in the step S20 includes:
step S21, obtaining the difference value between the signal intensity of the high-frequency sound signal in the currently detected environment sound signal and the signal intensity of the high-frequency sound signal in the last detected environment sound signal;
the step S30 includes:
and step S33, carrying out noise reduction operation on the earphone according to the high-frequency sound signal in the currently detected environment sound signal.
Specifically, as shown in fig. 9, the d line represents the signal intensity of the ambient sound signal after the user covers his hand, and the h line represents the signal intensity of the ambient sound signal before the user covers his hand. It can be seen that the signal intensity of the high-frequency sound signal after the hand covering action is large in change, the environment sound signal is larger than the high-frequency sound signal with the preset frequency, and the high-frequency sound signal is more obvious in change when the user takes the hand covering action. Illustratively, the preset frequency may be 1500 hz. Then, by detecting a high-frequency sound signal of the environmental sound signal, which is greater than the preset frequency, a difference between the signal intensity of the currently detected high-frequency sound signal and the signal intensity of the last detected high-frequency sound signal is calculated. When the difference value is larger than a preset threshold value, carrying out noise reduction operation on the earphone according to the high-frequency sound signal; and when the difference is smaller than or equal to the preset threshold, continuously acquiring the signal intensity of the next high-frequency sound signal, and calculating the difference between the signal intensity of the next high-frequency sound signal and the signal intensity of the currently detected high-frequency sound signal.
In the technical scheme of this embodiment, filter the signal frequency in the environment sound signal, detect the high frequency sound signal that is greater than preset frequency, because the signal strength that high frequency sound signal takes place for low frequency sound signal after the action of hand cover changes greatly, consequently detect high frequency sound signal and can determine more accurately whether there is the action of hand cover, improved the accuracy that earphone made an uproar.
