Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. Not all embodiments consistent with the present disclosure are represented in the following exemplary embodiments. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims.
Currently, many users prefer to wear headphones in public places or during sports, and use headphones to listen to music or talk. Typically, the configuration of the headset is fixed, i.e. the configuration parameters of the same model of headset are the same for each user. However, each user's ear is different, having a different auditory perception for the same audio, e.g., some users sound just like, some users feel loud, and some users feel soft, thus reducing the user experience.
In order to solve the above technical problems, the embodiments of the present disclosure provide a method for adjusting an audio parameter of an earphone, which may be suitable for an application scenario shown in fig. 1. Referring to fig. 1, the second headset 20 may be a standard detection headset within an off-line experience store, or a smart headset of another user. Taking a standard detection earphone as an example, on one hand, a user can experience the standard detection earphone to obtain the use experience, on the other hand, the user can utilize the standard detection earphone to obtain the ear canal data, after the ear canal data is obtained, the user can select to upload the ear canal data, at the moment, a second earphone or an electronic device connected with the second earphone can display a login page, and after an account and a password are input, the user can log in the cloud 30, and meanwhile, the ear canal data is stored in the cloud 30.
When the user takes another earphone (i.e., the first earphone 10), the first earphone 10 can be connected to the cloud end 30 and log in to the account; at this time, the ear canal data stored in advance may be downloaded from the cloud 30. The audio parameters of the first earphone 10 may be adjusted based on the ear canal data so that the audio parameters match the user's ears.
It should be noted that the first earphone 10 and the second earphone 20 may be wired earphones, wireless earphones, digital earphones, analog earphones, or a combination thereof. The cloud end 30 may be a server, a server cluster, a smart phone, a smart bracelet, a vehicle-mounted device, a smart home, or other electronic device. The electronic device may select a combination according to a specific scenario, which is not limited herein. It is understood that the cloud end 30 may include at least one storage space, each storage space may correspond to an account, and the corresponding storage space may be accessed through the account and the password, and data and ear canal data may be read and written. In one example, the cloud 30 is a dedicated storage device that stores ear canal data that can be read directly after login.
Fig. 2 is a flowchart illustrating a method of adjusting audio parameters of a headset according to an exemplary embodiment, which may be applied to an electronic device or a first headset, for which embodiments are described later as an executing device. Referring to fig. 2, a method for adjusting an audio parameter of an earphone includes steps 21 to 23, wherein:
In step 21, in response to a triggering operation of adjusting the audio parameters of the first earphone, ear canal data pre-stored in an account of a user who wants to wear the first earphone is obtained from the cloud.
In this embodiment, after the user takes the first earphone 10, the user may connect to the cloud terminal 30 through the interaction page displayed on the display screen in the first earphone 10, or connect the first earphone 10 to an electronic device such as a smart phone, and then connect to the cloud terminal 30. Taking the example that the first earphone 10 is connected to the cloud end 30 through a smart phone, a user may set the first earphone 10 through an interaction page or application software APP on the smart phone, for example, adjust audio parameters of the earphone.
After the first earphone 10 detects the triggering operation for adjusting the audio parameters, the first earphone 10 can acquire the pre-stored ear canal data in the account of the user who wants to wear the first earphone 10 from the cloud 30; alternatively, the electronic device first obtains the ear canal data from the cloud end 30 and stores the ear canal data locally, and then the first earphone 10 obtains the ear canal data from the local area of the electronic device.
In this embodiment, the ear canal data may include an amplitude difference and a phase difference, and may be acquired using the second earphone 20 shown in fig. 3. Referring to fig. 3, after the user wears the second earphone 20 to the ear 40, the processor in the second earphone 20 may play the set audio, and the speaker emits sound waves, and the sound wave signals radiate to the surroundings: a portion of the sound waves will directly enter the echo receiving device 22 (e.g., microphone) in the second earpiece 20, i.e., the unreflected sound wave signal; a part of the sound waves will propagate to the ear canal and the eardrum 41 of the ear and enter the echo receiving device 22 of the second earphone 20 after being reflected, i.e. the echo receiving device 22 may receive the sound waves 211 and the sound waves 212 after being reflected by the ear canal and/or the eardrum 41, and an audio signal is obtained.
In this embodiment, the processor of the second earphone 20 may process the audio signal to separate the first audio signal and the second audio signal. Because the processor can acquire the original waveform of the audio data currently played by the earphone and consider that certain attenuation exists from the original waveform to the first audio signal, the relation between the original waveform and the waveform of the first audio signal can be established in advance, so that the attenuation amplitude and the delay of the original waveform are obtained. Then, based on the above-described relationship, the second headphone 20 can extract the first audio signal from the audio signal given the original waveform. Then, the second earphone 20 may obtain a difference waveform between the actual waveform and the original waveform of the audio signal, and use the difference waveform as the waveform of the second audio signal, so as to obtain the second audio signal.
It should be noted that, in the processing process of the audio signal, reference may also be made to other related technologies, and in the case that the first audio signal and the second audio signal can be separated, the corresponding schemes fall within the protection scope of the disclosure.
In this embodiment, the second earphone 20 may acquire the amplitude difference and the phase difference of both the first audio signal and the second audio signal. The amplitude difference is used for representing the amplitude attenuation degree of the ear canal to the first audio signal, and the phase difference is used for representing the delay degree of the depth of the eardrum to the first audio signal. For example, the first audio signal is Asin (wt+a) and the second audio signal is Bsin (wt+b), the amplitude difference may be-20 log (B/A), and the phase difference may be B-a.
In this embodiment, after the amplitude difference and the phase difference are obtained, at this time, the second earphone 20 or the electronic device connected with the second earphone 20 may display a login page of the cloud end 30, the user may log in to the cloud end 30 after inputting an account and a password, and the second earphone 20 uploads the amplitude difference and the phase difference as ear canal data to the cloud end 30. The cloud 30 stores the ear canal data in a storage area corresponding to the account.
The account may be a character string, a mobile phone number, a mailbox, or biological information such as a fingerprint, an iris, an auricle, and a face. In the case of taking a fingerprint as an example, when the user needs to log onto the cloud 30, the electronic device may scan the fingerprint of the user and directly enter the storage space corresponding to the fingerprint.
In practical applications, the second earphone 20 may also upload other parameters such as its own model number as a part of the ear canal data to the cloud end 30 at the same time, which is not limited herein.
In step 22, an audio level corresponding to the user's ear is determined based on the ear canal data.
In practical applications, the models of the second earphone 20 and the first earphone 10 may be different, for example, the second earphone 20 is an external earphone and the first earphone 10 is an in-ear earphone. Thus, the processor of the first earpiece 10 may compensate for the downloaded ear canal data, see fig. 4:
In step 41, the processor of the first earphone 10 may obtain the model numbers of the second earphone 20 and the first earphone 10. Wherein the model is related to parameters of the earphone, which may include earphone hardware parameters such as the shape of the earphone, the installation position of each device in the earphone, etc., and earphone software parameters such as audio parameters in the software about the earphone, etc. In step 42, when the models of the second earphone 20 and the first earphone 10 are different, if any parameter of the first earphone 10 and the second earphone is different, that is, the models are different, compensation data of the first earphone 10 relative to the second earphone 20 is obtained; the compensation data includes phase compensation data and amplitude compensation data. The phase compensation data may be a difference of phases caused when the same audio signal propagates in the ear canal due to different models of the two headphones, where the difference of phases is a difference between a first phase difference and a second phase difference, where the first phase difference is a first phase difference that can be determined by a first audio signal and a second audio signal detected after the same audio signal is transmitted by the first headphone; the second phase difference refers to a second phase difference that can be determined by the first audio signal and the second audio signal detected after being transmitted by the second earphone. The compensation data may be obtained through a large amount of experimental data experiments, or may be obtained through calculation through artificial intelligence algorithms such as deep learning after training, neural networks, and the like, which is not limited herein. The method for acquiring the amplitude compensation data is the same as the method for acquiring the phase compensation data, and will not be described here again. In step 43, the phase difference is compensated according to the phase compensation data, the amplitude difference is compensated according to the amplitude compensation data, and the compensated ear canal data is used as the ear canal data of the first earphone 10. In this embodiment, by compensating the ear canal data, the deviation caused by the model difference of the first earphone 10 and the second earphone 20 can be eliminated, which is beneficial to improving the accuracy of the subsequent calculation of the audio level.
In this embodiment, the first earphone 10 may determine the audio level corresponding to the ear of the user who wants to wear the first earphone 10 based on the ear canal data, and referring to fig. 5, the processor of the first earphone 10 may obtain the preset amplitude difference threshold and the preset phase difference threshold (corresponding to step 51). The amplitude difference threshold and the phase difference threshold can be obtained through statistics in a big data mode, for example, the amplitude difference threshold can be a proportion value of 20%, and the phase difference can be 5-10 degrees. Of course, a large number of tests may be used to confirm the amplitude difference and/or the phase difference, for example, a certain number of volunteers (e.g. 1000) may be selected, ear canal data may be collected once for each volunteer, and the amplitude difference and the phase difference according to the ear canal data may be determined according to feedback of the volunteer on the audio effect. Then, the amplitude differences and the phase differences of the same feedback type are counted, and the average value of the amplitude differences and the average value of the phase differences, or the maximum value of the amplitude differences and the maximum value of the phase differences are obtained; the average, or maximum weighted (e.g., multiplied by a fraction) value is then used as the magnitude and phase difference thresholds. The technician can set the amplitude difference threshold and the phase difference threshold according to specific scenes, and the corresponding scheme falls into the protection scope of the disclosure.
With continued reference to fig. 5, the processor may compare the magnitude difference to a magnitude difference threshold and the phase difference to a phase difference threshold to obtain a first comparison result and a second comparison result, respectively (corresponding to step 52). The first comparison result comprises that the amplitude difference is larger than an amplitude difference threshold value or the amplitude difference is smaller than the amplitude difference threshold value; the second comparison result includes the phase difference being less than the phase difference threshold, or the phase difference being greater than the phase difference threshold.
With continued reference to fig. 5, the processor may obtain an audio level of an ear wearing the headset based on the first comparison result and the second comparison result (corresponding to step 53), and may include:
and when the first comparison result indicates that the amplitude difference is larger than the amplitude difference threshold value and the second comparison result indicates that the phase difference is larger than the phase difference threshold value, determining the audio grade as a first grade.
And when the first comparison result shows that the amplitude difference is larger than the amplitude difference threshold value and the second comparison result shows that the phase difference is smaller than the phase difference threshold value, determining that the audio grade is a second grade.
And when the first comparison result shows that the amplitude difference is smaller than the amplitude difference threshold value and the second comparison result shows that the phase difference is larger than the phase difference threshold value, determining that the audio grade is a second grade.
And when the first comparison result shows that the amplitude difference is smaller than the amplitude difference threshold value and the second comparison result shows that the phase difference is smaller than the phase difference threshold value, determining that the audio grade is a third grade.
It should be noted that, in the above embodiment, only the case that the audio level has 3 levels is illustrated, and a technician may increase the corresponding level according to a specific scene, and at this time, the number of the amplitude difference threshold and the phase difference threshold may be increased, for example, when the amplitude difference threshold and the phase difference threshold are respectively 2, the audio level may be increased to 9. Corresponding schemes fall within the protection scope of the present disclosure.
In step 23, when the audio level is a level other than the target level, the audio level of the first earphone is adjusted to the target level, so that the audio level of the first earphone matches with the audio level corresponding to the ear.
In this embodiment, the third level may be taken as the target level, the processor determines whether the current audio level is the third level, and when the current audio level is the third level, the processor may not adjust the audio parameters of the earphone, and returns to step 21; when the current audio level is a level other than the third level, such as the first level or the second level, the processor determines to adjust the audio level of the headphones.
Referring to fig. 6, in step 61, when the audio level is the first level, the cavity structure of the first earphone 10 is adjusted so that the audio level of the first earphone is changed from the first level to the second level. For example, referring to fig. 7, the processor adjusts the cavity structure of the first earphone 10 in a first audio level, in a manner that the processor sends a control signal to the movable device to move the movable device to the target position.
When the movable device moves close to the eardrum, the cavity structure of the earphone becomes smaller, and in this case, the high-frequency effect of the output sound wave becomes better, and the earphone is suitable for the ear insensitive to the high-frequency component in the sound wave, such as the short-ear-canal scene caused by the shallow eardrum. When the movable device moves away from the eardrum, the cavity structure of the earphone becomes large, the low-frequency effect of the output sound wave can be improved, and the earphone is suitable for ears insensitive to low-frequency components in the sound wave, such as scenes with long auditory canal caused by deep eardrum.
With continued reference to fig. 6, in step 62, when the audio level is the second level, the processor may adjust the frequency response characteristics of the speakers in the headphones to change the audio level of the first headphone from the second level to a third level, which is the target level. For example, with continued reference to fig. 7, the processor adjusts the audio parameters of the headphones in the second level of the audio level, where the adjustment may be EQ (equalliser) and DRC (Dynamic Range Control), and after the audio level is determined, an adjustment target value of the audio parameters may be determined, and then the audio parameters may be directly adjusted to the adjustment target value. Of course, the processor may also adjust the audio parameters according to the set step size, at which time the user may listen to the audio signal, and stop adjusting when the listening effect is best, at which time it is determined to adjust to the target level.
It should be noted that, when the audio level is the first level, the processor needs to perform step 61 and step 62. When the audio level is the second level, the processor needs to perform step 62. When the audio level is the third level, the processor determines not to adjust the audio level.
