Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repeated descriptions will be omitted.

As shown in FIG. 1 , an embodiment of the present invention discloses a method for controlling a noise reduction mode of an earphone, and the method includes the following steps:

S10: The noise reduction mode of the earphone is turned on, and the ambient sound signal is collected. That is, the working state of the noise reduction mode of the earphone and the ambient sound signal are collected respectively, and it is determined that the noise reduction mode of the earphone has been turned on, and then step S20 is executed.

S20: Determine whether the amplitude deviation value of the ambient sound signal is greater than a first preset threshold. If so, step S30 is executed. If not, return to step S10. Specifically, when the amplitude deviation value of the collected environmental sound signal is greater than the first preset threshold, it means that high noise occurs in the surrounding environment, such as a danger warning sound in the external environmental sound or a sudden call from a friend. At this time, the noise reduction mode needs to be turned off, so that the user can pay attention to the abnormal sound of the surrounding environment in time.

Wherein, there is no limitation in the present invention as to the way of judging the occurrence of high noise in the ambient sound signal. For example, the difference between the amplitude of the ambient sound signal at the current moment and the average value of the amplitude of the ambient sound signal in the previous x seconds can be compared with a preset threshold; The ratio between the average value of the x-second ambient sound signal amplitude and the magnitude of a preset threshold, etc.

S30: Turn off the noise canceling mode of the headset. That is, the noise reduction mode of the headset is switched from an on state to an off state. In this way, the user can hear the outside sound more clearly, and timely react. Prevent possible accidents caused by users not hearing the danger warning sound in time.

S40: Continue to collect the ambient sound signal, and determine whether the amplitude deviation value of the ambient sound signal is less than a second preset threshold. If yes, step S50 is executed. If not, step S60 is executed. For example, if the ambient sound signal is collected at the current moment in step S10, then step S40 is to determine that the ambient sound signal continues to be collected in the subsequent period of the current moment.

If the amplitude deviation value of the continuously collected ambient sound signal is smaller than the second preset threshold, it means that the ambient sound signal has reached a stable state, for example, after the user moves from a quieter environment to a noisy environment, the high noise reaches a continuous state; Or, after the previous sudden danger warning sound (high noise) stops, no other danger occurs in the surrounding environment, so that the collected ambient sound signal drops to a stable state.

The above-mentioned amplitude deviation values are all obtained according to the average value of the first amplitude value corresponding to the ambient sound signal at the current moment and the first amplitude value of the ambient sound signal x seconds before the current moment. Among them, x is a preset parameter, and x is a positive number. The first preset threshold is greater than the second preset threshold.

Specifically, the amplitude deviation value of the above ambient sound signal is calculated according to the following formula: D(t)=|[ A _s ( t )- A _avg ( x )]|/[ A _avg ( x )]

Among them, D(t) represents the amplitude deviation value of the environmental sound signal at the current time t, A_s (t) represents the first amplitude value corresponding to the environmental sound signal at the current time, and _Aavg ( x ) represents the environmental sound signal x seconds before the current time The average of the first amplitude values of . For example, the current moment is the 20th second, and x can take a value of 10. Then A _avg ( x ) represents the average value of the first amplitude values of the ambient sound signals in the previous 10 seconds of the current time, that is, the average value of the first amplitude values of the ambient sound signals from the 10th second to the 19th second. As ( _t ) represents the first amplitude value corresponding to the ambient sound signal in the 20th second.

In this embodiment, the first amplitude value A _s ( t ) corresponding to the environmental sound signal at the current moment is calculated according to the following formula:

Among them, t represents the current time. For example, when _t is 20, As ( t ) represents the first amplitude value corresponding to the ambient sound signal collected in the 20th second, which is equal to the absolute value of the amplitude of the ambient sound signal collected at all sampling points in the 20th second and. N represents the number of sampling points in the current moment, r represents the sampling points, and Ap ( _r ) represents the amplitude value of the ambient sound signal collected at the rth sampling point in the current moment. N is a preset parameter. In this embodiment, N is 44100, and the value of N is not limited in this application.

In this embodiment, the average _{value Aavg} ( x ) of the first amplitude values of the ambient sound signal x seconds before the current moment is calculated according to the following formula:

就表示從第10秒到第19秒 採集到的環境聲音訊號的幅值的和。 Wherein, _As ( m ) represents the first amplitude value corresponding to the ambient sound signal at the m th time. Exemplarily, when t is 20 and x is 10,

It represents the sum of the amplitudes of the ambient sound signals collected from the 10th to the 19th second.

S50: Turn on the noise canceling mode of the headset. That is, when it is determined that the high noise reaches a continuous state, that is, the amplitude deviation value of the ambient sound signal is less than the second preset threshold, that is, in an environment with stable external noise, the safety of the user has been confirmed. Noise reduction has been implemented again to isolate external noise. It also means that the noise reduction mode of the headset is switched from an off state to an on state. Therefore, it is not necessary for the user to manually turn on noise reduction again, which saves the user's operation and is beneficial to improving the user's earphone experience. Of course, the user can also manually turn on the noise reduction mode again.

S60, the noise reduction mode of the earphone remains off, and the process returns to step S40.

In this embodiment, after a large number of experimental tests, it is found that it is reasonable to set the first preset threshold to 2 and the second preset threshold to 0.5, so that the user can fully and timely hear the danger in the surrounding environment sound. Warning sound. This application does not limit this.

As shown in FIG. 2 , in another embodiment of the present invention, on the basis of the above embodiment, the above step S30 further includes: reducing the output volume of the earphone from the first volume value to the second volume value. In this way, the user can hear the external environment sound more clearly, which is especially suitable for the scene where the user is called by a friend and needs to talk. In this way, the user can easily talk and hear each other's voice without requiring the user to manually turn down the volume. .

The above step S50 further includes: restoring the output volume of the earphone to the first volume value. That is, the user may continue to listen to songs by using the earphone, so that the output volume of the earphone can be restored, and the volume can be restored according to the user's habit of listening to songs, and the use experience is better.

As shown in FIG. 2 , in this embodiment, step S70 is further included between step S30 and step S40: when the collected signal is the signal of the earphone wearer speaking, return to step S30; otherwise, execute step S40. During the specific implementation, the way in which the earphone wearer can be judged to be speaking can be determined through bone voiceprint signal recognition and/or dual microphone beamforming, etc., and it can be determined that the collected signal is the signal of the earphone wearer speaking, then return to step S30, that is, about The noise-cancelling mode of the headphones remains off. If otherwise, step S40 is performed. Specifically, when the user is talking, he may be talking with a friend, and the noise reduction mode of the earphone is kept off, so that the user can hear the other party's voice more clearly and improve the user experience.

As shown in FIG. 3 , an embodiment of the present invention further discloses a headphone noise reduction mode control system 3 . The system includes: a state acquisition module 31 for collecting the working state of the headphone noise reduction mode and ambient sound signals. The first judging module 32, when the earphone is in the noise reduction mode, uses for determining whether the amplitude deviation value of the ambient sound signal is greater than the first preset threshold. If so, send a noise reduction shutdown command to the noise reduction shutdown module to inform the noise reduction shutdown module to start performing internal operations to turn off the headset noise reduction mode. If not, the loop operation command is sent to the state acquisition module, that is, the state acquisition module is told to perform the internal operation again. The noise reduction off module 33 is used to turn off the noise reduction mode of the earphone after receiving the noise reduction off instruction. The second determination module 34 is configured to determine whether the amplitude deviation value of the ambient sound signal is smaller than the second preset threshold when the earphone is in the noise reduction mode off. If so, send a noise reduction turn-on command to the noise reduction turn-on module to inform the noise reduction turn-on module to start performing internal operations to turn on the earphone noise reduction mode. If not, keep noise reduction off. The noise reduction enable module 35 is used to enable the noise reduction mode of the earphone after receiving the noise reduction enable instruction.
