Referring to
Specifically, the earphone includes a first earphone and a second earphone, the first earphone may be a right earphone or a left earphone, and the second earphone is another earphone. The internal audio information of the environment where the earphone is located (that is, the cavity formed by the earphone and the user's ear canal) and the external audio information of the external environment collected by the earphone can be collected by the in-ear microphone of the earphone in real time or periodically. The internal audio information and the external audio information are processed to obtain the leakage information of the sound wave, and further obtain earphone wearing fit information.
In another embodiment, the following steps are also included before step S100:
Specifically, the preset trigger information may be user touch information and/or voice control information, or instruction information issued by the built-in control device of the earphone, such as a trigger instruction issued after reaching a preset trigger period. It is determined that whether the earphone has received the preset trigger information; if the earphone has received the preset trigger information, the step of obtaining the wearing fit information of the earphone is performed. If the earphone does not receive the preset trigger information, no subsequent operations are performed. In this way, it is avoided that in the case of obtaining the wearing fit information of the earphones in real time, the power consumption of the earphones is high, resulting in a decrease in battery life of the earphones. In this embodiment, the battery life of the earphone is improved by performing step S100 only after receiving the preset trigger information.
In another embodiment, the wearing fit information also includes the current noise reduction amount of the earphone, and after step S100, the following steps are further included:
Specifically, the wearing fit information also includes the current noise reduction amount of the earphone; according to the internal audio information of the cavity formed by the earphone and the user's ear canal collected by the earphone's in-ear microphone and the external audio information in the external environment collected by the out-of-ear microphone, the current noise reduction amount can be obtained. The current noise reduction amount can be the ratio of the audio energy collected by the external-ear microphone and the internal-ear microphone; it can also be the ratio of the audio amplitude collected by the external-ear microphone and the internal-ear microphone; it can also be the difference in the LOG domain of the audio signal collected by the external-ear microphone and the internal-ear microphone; it can also be the ratio of the power or amplitude in the frequency domain after the audio signals collected by the external-ear microphone and the internal-ear microphone are first Fourier transformed. The preset minimum noise reduction amount is the minimum noise reduction amount that can be achieved by compensating for leaked sound waves when the wearing fit of the earphones obtained through experimental testing and calibration is the preset minimum wearing fit. By determining whether the current noise reduction amount is less than the preset minimum noise reduction amount; if the current noise reduction amount is less than the preset minimum noise reduction amount, it indicates that the current wearing fit of the earphone is lower than the preset minimum wearing fit; if the preset minimum noise reduction amount cannot be reached, then the preset reminder message will be output to remind the user to wear the earphones again, so that the user can put on the earphones again and improve the wearing fit; if the current noise reduction amount is greater than or equal to the preset minimum noise reduction amount, step S200 is executed.
Step S200, according to the wearing fit information, obtaining the optimal noise reduction information of the earphone;
Specifically, the wearing fit information includes the wearing fit information of the first earphone and the wearing fit information of the second earphone. According to the wearing fit information of the first earphone and the wearing fit information of the second earphone, based on the corresponding relationship between preset different wearing fit degrees and the theoretical optimal noise reduction amount, the optimal noise reduction information of the earphone can be obtained (the optimal noise reduction amount in the wearing state of the first earphone and the optimal noise reduction amount in the wearing state of the second earphone). The wearing fit information can be obtained through preset sensors (such as capacitive sensors, optical sensors, etc.) or sound wave leakage. For example, the wearing fit information includes fit grades, which are divided into a preset number of fit grades from tight to loose. The corresponding optimal noise reduction amount can be obtained according to the preset mapping table of fit grades and optimal noise reduction.
In another embodiment, the optimal noise reduction information includes a first optimal noise reduction amount and a second optimal noise reduction amount, and step S200 includes: the wearing fit information includes the first frequency response information of the first earphone and second frequency response information of the second earphone;
Step S210, according to the first frequency response information, the second frequency response information, and the mapping table between the preset frequency response information and the optimal noise reduction amount, obtaining the first optimal noise reduction amount and the second optimal noise reduction amount.
Specifically, the wearing fit information includes first frequency response information in a wearing state of the first earphone and second frequency response information in a wearing state of the second earphone. The first frequency response information and the second frequency response information may be in the form of a frequency response curve; the first frequency response information is a first frequency response curve, and the second frequency response information is a second frequency response curve; by fitting the first frequency response curve and the second frequency response curve with the frequency response curves of the preset frequency response information in the mapping table of the preset frequency response information and the optimal noise reduction amount respectively, the optimal noise reduction amount corresponding to the frequency response curve with the highest fitting degree between the first frequency response curve and the second frequency response curve is used as the corresponding first optimal noise reduction amount and second optimal noise reduction amount. Similarly, it can be known that the frequency response values corresponding to the low frequency, intermediate frequency and high frequency in the first frequency response information and the second frequency response information can also be compared with the preset frequency response information in the mapping table to obtain the corresponding optimal noise reduction amount.
Step S300, obtaining a common noise reduction amount according to the optimal noise reduction information;
Specifically, the optimal noise reduction information may include a first optimal noise reduction amount and a second optimal noise reduction amount. The first earphone and the second earphone can interact to obtain the optimal noise reduction amount of the other party through a preset communication channel between the two, such as a wire, a Bluetooth link, etc., that is, after obtaining the first optimal noise reduction amount, the first earphone sends the first optimal noise reduction amount to the second earphone through the preset communication channel, and after obtaining the second optimal noise reduction amount, the second earphone sends the second optimal noise reduction amount to the first earphone through the preset communication channel. Thus, both the first earphone and the second earphone obtain the first optimal noise reduction amount and the second optimal noise reduction amount; and then the first optimal noise reduction amount and the second optimal noise reduction amount can be in comparison, and the optimal noise reduction amount with a lower value is selected as the common noise reduction amount, or any noise reduction amount between the preset minimum noise reduction amount and the lower value optimal noise reduction amount can be selected as the common noise reduction amount.
In another embodiment, step S300 includes:
Specifically, it is determined whether the first optimal noise reduction amount is greater than the second optimal noise reduction amount; if the first optimal noise reduction amount is greater than the second optimal noise reduction amount, the second optimal noise reduction amount is used as the common noise reduction amount; if the first optimal noise reduction amount is less than or equal to the second optimal noise reduction amount, the first optimal noise reduction amount is used as the common noise reduction amount. By selecting the optimal noise reduction amount with a lower numerical value as the common noise reduction amount, both the first earphone and the second earphone can achieve the common noise reduction amount, so that the final noise reduction effect of the first earphone and the second earphone is consistent, thereby achieving better noise reduction effect.
Step S400, controlling the first earphone and the second earphone to perform noise reduction according to the common noise reduction amount.
Specifically, by adjusting the current active noise reduction parameters of the first earphone and the second earphone, the current noise reduction amounts of the first earphone and the second earphone are both adjusted to the common noise reduction amount.
In another embodiment, step S400 includes the following steps:
Step S410, adjusting the active noise reduction parameters of the first earphone and the second earphone, so as to adjust the current noise reduction amount of the first earphone and the second earphone to the common noise reduction amount in a first preset amplitude.
Specifically, by adjusting the active noise reduction parameters of the first earphone and the second earphone, the current noise reduction amount of the first earphone and the second earphone is adjusted to the common noise reduction amount by a first preset amplitude. The first preset amplitude is the preset adjustment range for the current noise reduction amount, for example, the current noise reduction amount is 15 dB, and the common noise reduction amount is 25 dB; then the current noise reduction amount can be first adjusted from 15 dB to 20 dB through the active noise reduction parameters, and then adjusted from 20 dB to 25 dB, so as to realize smooth switching of the first earphone and the second earphone from the current noise reduction amount to the common noise reduction amount.
In the first embodiment of the present application, the wearing fit information of the earphone can be acquired by detecting the leakage information of the sound wave in real time or periodically. The wearing fit information includes wearing fit information of the first earphone and wearing fit information of the second earphone. The optimal noise reduction information corresponding to the first earphone and the second earphone can be obtained based on the corresponding relationship between different wearing fit degrees and the theoretical optimal noise reduction amount according to the wearing fit information of the first earphone and the wearing fit information of the second earphone. By analyzing the optimal noise reduction information, the amount of noise reduction that can be achieved by both the first earphone and the second earphone is obtained as the common noise reduction amount; and by adjusting the current active noise reduction parameters of the first earphone and the second earphone, so as to adjust the current noise reduction amounts of the first earphone and the second earphone to the common noise reduction amount. In this embodiment, by obtaining the optimal noise reduction information of the first earphone and the second earphone, and then the noise reduction amount of the first earphone and the second earphone is adjusted to the common noise reduction amount that both can achieve, thus while maintaining a relatively high amount of noise reduction, the consistency of the noise reduction effects of the first earphone and the second earphone is achieved.
Further, referring to
Step S500, adjusting the active noise reduction parameters of the first earphone and the second earphone, so as to monotonically decrease the current noise reduction amount of the first earphone and the second earphone to the preset minimum noise reduction amount in a second preset amplitude.
Specifically, since the process of obtaining the common noise reduction amount by analyzing the wearing fit information in step S200 and step S300 often takes a certain amount of time to complete, therefore, while obtaining the common noise reduction amount, you can adjust the active noise reduction parameters of the first earphone and the second earphone. The current noise reduction amount of the first earphone and the second earphone is monotonously decreased to the preset minimum noise reduction amount at the second preset amplitude, and the above-mentioned monotonous decrease is to decrease according to the single change direction of the value from large to small, which is similar to the meaning of monotonous decrease in the monotonic function, that is, the numerical change of the current noise reduction amount is uniform during the process of adjusting the current noise reduction amount to the preset minimum noise reduction amount, without a combination of increasing and decreasing. The second preset amplitude is also a preset adjustment range for the current noise reduction amount, and the second preset amplitude may be the same adjustment range as the first preset amplitude, or may be the different adjustment range. For example, the current noise reduction amount of the first earphone is 15 dB, the current noise reduction amount of the second earphone is 20 dB, and the preset minimum noise reduction amount is 5 dB. Then the first earphone can reduce the current noise reduction amount of the first earphone from 15 dB to 10 dB first by adjusting the active noise reduction parameters, and then from 10 dB to 5 dB; by adjusting the active noise reduction parameters, the first earphone can first decrease the current noise reduction of the second earphone from 20 dB to 15 dB, then from 15 dB to 10 dB, and finally from 10 dB to 5 dB. It can be understood that the current noise reduction amounts of the first earphone and the second earphone may also be monotonously decreased to a preset minimum noise reduction amount at the same time. Then the active noise reduction parameters of the first earphone and the second earphone can be adjusted according to the common noise reduction amount, and the noise reduction amount of the first earphone and the second earphone is increased from the preset minimum noise reduction amount to the common noise reduction amount with the first preset amplitude. In this embodiment, first the current noise reduction amount of the first earphone and the second earphone is monotonously decreased to the preset minimum noise reduction amount with the second preset amplitude, so that the first earphone and the second earphone can be quickly adjusted to the same noise reduction effect; after the common noise reduction amount is obtained, the noise reduction amount of the first earphone and the second earphone is adjusted from the preset minimum noise reduction amount to the common noise reduction amount, so that the first earphone and the second earphone maintain the same noise reduction effect while increasing the noise reduction amount. The noise reduction effect of the first earphone and the second earphone can be adjusted smoothly in real time, avoiding the hysteresis of the adjustment of the noise reduction effect and the howling caused by the sudden change of the noise reduction amount, thus bringing a better user experience.
