Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.
Currently, many users prefer to wear earphones in public places or during sports, and listen to music or talk using the earphones. 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 and has different hearing perceptions for the same audio, e.g., some users sound just, some users feel louder, and some users feel louder, thus reducing the user experience.
To solve the above technical problem, an embodiment of the present disclosure provides a method for adjusting an audio parameter of an earphone, which may be applied to the application scenario shown in fig. 1. Referring to fig. 1, the second earpiece 20 may be a standard test earpiece in an off-line experience store, or a smart earpiece for other users. Using the standard to detect the earphone as an example, on the one hand, the user can experience this standard and detect the earphone, obtains using experience, and on the other hand, the user can utilize this standard to detect the earphone and obtain above-mentioned duct data, obtains duct data back, and the user can select to upload duct data, and the second earphone or the electronic equipment who is connected with the second earphone can show the landing page this moment, can log in the high in the clouds 30 after input account and password, with duct data storage to this high in the clouds 30 simultaneously.
When the user takes another headset (i.e. the first headset 10), the first headset 10 can be connected to the cloud 30 and log in the account; at this time, pre-stored ear canal data may be downloaded from the cloud 30. The audio parameters of the first earpiece 10 may be adjusted based on the ear canal data to match the audio parameters to the user's ear.
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 30 may be a server, a server cluster, a smart phone, a smart band, a vehicle-mounted device, a smart home, or other electronic devices. The electronic device may select a combination according to a specific scenario, which is not limited herein. It can be understood that at least one storage space may be included in the cloud 30, each storage space may correspond to an account, and the corresponding storage space may be accessed through the account and the password, and read and write data and ear canal data. In one example, the cloud 30 is a dedicated storage device that stores ear canal data, which can be read directly after logging in.
Fig. 2 is a flow chart 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, followed by describing embodiments for the first headset as an executing device. Referring to fig. 2, a method for adjusting audio parameters of a headphone includes steps 21 to 23, where:
in step 21, in response to a trigger operation for adjusting an audio parameter of the first earphone, ear canal data pre-stored in an account of a user who wants to wear the first earphone is acquired from the cloud.
In this embodiment, after the user takes the first earphone 10, the user can connect to the cloud 30 through the interactive page displayed on the display screen of 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 30. Taking the first headset 10 connected to the cloud 30 through the smart phone as an example, the user may set the first headset 10 through an interactive page or an application APP on the smart phone, for example, adjust an audio parameter of the headset.
After detecting the trigger operation indicating that the audio parameter is adjusted, the first earphone 10 may obtain ear canal data pre-stored in an account of a 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 30 and stores the data locally, and then the first earphone 10 obtains the ear canal data from the local of the electronic device.
In the present embodiment, the ear canal data may include an amplitude difference and a phase difference, which may be acquired by the second earpiece 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 can 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 sound wave signals that are not reflected; a part of the sound waves will propagate to the ear canal and eardrum 41 of the ear and will be reflected back into the echo receiving device 22 in the second earpiece 20, i.e. the echo receiving device 22 can receive the sound waves 211 and the sound waves 212 reflected back through the ear canal and/or eardrum 41 of the ear to obtain an audio signal.
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. The processor can acquire the original waveform of the currently played audio data of the earphone, and the relation between the original waveform and the first audio signal waveform can be pre-established in consideration of the fact that the original waveform possibly has a certain attenuation to the first audio signal, 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 may extract the first audio signal from the audio signal with the original waveform known. Then, the second headphone 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, other related technologies may also be referred to in the processing procedure of the audio signal, and in the case that the first audio signal and the second audio signal can be separated, the corresponding scheme falls within the protection scope of the present disclosure.
In this embodiment, the second headphone 20 may acquire the amplitude difference and the phase difference between 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 time delay degree of the eardrum depth 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 to the second earphone 20 may display a login page of the cloud 30, the user may login to the cloud 30 after inputting an account and a password, and the second earphone 20 uploads the amplitude difference and the phase difference to the cloud 30 as ear canal data. The cloud 30 stores the ear canal data in a storage area corresponding to the account.
It should be noted that the account may be information such as a character string, a mobile phone number, a mailbox, and the like, and may also be biological information such as a fingerprint, an iris, an auricle, a face, and the like. For example, when the account is a fingerprint, and needs to log in 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 model as a part of the ear canal data to the cloud 30 at the same time, which may be implemented as well, and 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 practice, the second earphone 20 and the first earphone 10 may be of different models, 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 earpiece 10 may obtain the model of the second earpiece 20 and the first earpiece 10. The model is related to parameters of the earphone, and may include earphone hardware parameters such as the shape of the earphone, the installation position of each device in the earphone, and earphone software parameters such as audio parameters related to the earphone in software. In step 42, when the models of the second earphone 20 and the first earphone 10 are different, if any one of the parameters of the first earphone 10 and the second earphone is different, that is, the models are different, the 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 phase differences caused by different models of the two earphones when the same audio signal propagates in the ear canal, and the phase differences are differences 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 the first audio signal and the second audio signal detected after the same audio signal is transmitted by the first earphone; the second phase difference is 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 headphone. It should be noted that the compensation data may be obtained through a large number of experimental data experiments, or may be obtained through artificial intelligence algorithm calculation such as deep learning and neural network after training, which is not limited herein. The amplitude compensation data is obtained in the same manner as the phase compensation data, and will not be described herein 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 channel data, the deviation caused by the model difference between the first earphone 10 and the second earphone 20 can be eliminated, which is beneficial to improving the accuracy of the subsequent audio level calculation.
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, referring to fig. 5, the processor of the first earphone 10 may obtain a preset amplitude difference threshold and a preset phase difference threshold (corresponding to step 51). The amplitude difference threshold and the phase difference threshold can be obtained by 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 can be used to confirm the amplitude difference and/or the phase difference, for example, a certain number of volunteers (for example, 1000 volunteers) can be selected, ear canal data is collected once for each volunteer, and the amplitude difference and the phase difference in the ear canal data can be determined according to the feedback of the volunteer on the audio effect. Then, counting the amplitude difference and the phase difference of the same feedback type, and acquiring the average value of the amplitude difference and the average value of the phase difference, or the maximum value of the amplitude difference and the maximum value of the phase difference; the average, or maximum weighted (e.g., multiplied by a fraction) value is then used as the magnitude difference threshold and the phase difference threshold. Technicians can set an amplitude difference threshold and a 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 first and second comparison results, respectively (corresponding to step 52). Wherein the first comparison result comprises that the amplitude difference is greater 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 according to the first comparison result and the second comparison result (corresponding to step 53), which 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 level as a first level.
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 smaller than the phase difference threshold value, determining the audio level as a second level.
And determining the audio level as a second level when the first comparison result indicates that the amplitude difference is smaller than the amplitude difference threshold and the second comparison result indicates that the phase difference is larger than the phase difference threshold.
And determining the audio level as a third level when the first comparison result indicates that the amplitude difference is less than the amplitude difference threshold and the second comparison result indicates that the phase difference is less than the phase difference threshold.
It should be noted that, the above embodiment only illustrates a case where there are 3 audio levels, and a technician may increase corresponding levels according to a specific scene, 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 levels may be increased to 9. The corresponding solutions fall within the scope of protection 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 a 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 parameter 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 to change the audio level of the first earphone from the first level to the second level. For example, referring to fig. 7, the processor may adjust the cavity configuration of the first earpiece 10 in the audio level of the first level in such a way that the processor sends a control signal to the movable device to move the movable device to the target position.
It should be noted that 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 an ear which is not sensitive to the high-frequency component in the sound wave, for example, a scene of short ear canal caused by shallow eardrum. When the movable device moves away from the eardrum, the cavity structure of the earphone is enlarged, the low-frequency effect of the output sound wave is improved, and the earphone is suitable for the ear which is insensitive to low-frequency components in the sound wave, such as a scene with a long auditory canal caused by the depth of the eardrum.
With continued reference to fig. 6, at 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, when the audio level is the second level, the audio parameter of the headphone is adjusted in a manner of eq (equal) and drc (dynamic Range control), and after the audio level is determined, the adjustment target value of the audio parameter may be determined, and at this time, the adjustment target value is directly adjusted. 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 the adjustment when sensing that the listening effect is best, at which time the adjustment to the target level is determined.
It should be noted that, when the audio level is the first level, the processor needs to execute 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 a third level, the processor determines not to adjust the audio level.
Therefore, in the embodiment of the present disclosure, when a trigger operation for adjusting an audio parameter of a first earphone is detected, ear canal data pre-stored in an account of a user who wants to wear the first earphone is acquired from a cloud; then, determining an audio level corresponding to the ear of the user based on the ear canal data; and then, when the audio level is a level other than the target level, adjusting the audio level of the first earphone to the target level.
