Referring to fig. 1, a tuning method of an earphone according to an embodiment of the present application, where the earphone includes an earphone body and an air pressure measuring sensor disposed in the earphone body, includes:

s1: the method comprises the steps that a sine wave frequency sweeping signal in a specified frequency range is played in an ear where a first user currently wears an earphone;

s4: and calculating a first frequency response curve corresponding to the first user according to the first air pressure curve, the simulated head standard air pressure curve and the simulated head standard frequency response curve.

As described in the foregoing steps S1 to S4, the main execution body of the embodiment of the present method is an earphone, where the earphone includes an earphone body and an air pressure measuring sensor disposed in the earphone body, and the earphone may be an ear-plug type, in-ear type, head-mounted or ear-hanging earphone, etc. According to the embodiment, the change condition of the air pressure of the ear canal after the ear of the user wears the earphone is measured by using the air pressure measuring sensor, the frequency response curve suitable for the user is rapidly and conveniently calculated according to the pre-stored simulated head standard air pressure curve and the simulated head standard frequency response curve, the obtained frequency response curve can effectively meet the high-quality requirement of the user on audio, and the user experience of using the earphone is improved. Specifically, a sine wave frequency sweep signal at a specified frequency range is first played in the ear where the first user is currently wearing the headset. Wherein, for pure tones below 20Hz and above 20KHz, most people can not feel the existence of sound no matter how high the sound level is, so the specified frequency range can be set to be 20Hz-20 KHz. The voltage value corresponding to the sine wave frequency sweeping signal is not particularly limited, and the voltage value is obtained only by ensuring that the sine wave frequency sweeping signal of 20Hz-20KHz played by human ears when wearing earphones is not irritative. In addition, when it is detected that the first user is currently wearing the earphone, the sine wave frequency sweep signal in the specified frequency range can be played in the ear where the first user currently wears the earphone. The wearing state may include a state in which the first user wears the headset in the left ear or a state in which the first user wears the headset in the right ear, and whether the first user is currently in a wearing state in which the headset is worn may be detected by a distance sensor provided in the headset. And then acquiring a first air pressure curve in the ear canal of the ear of the first user currently wearing the earphone through the air pressure measuring sensor. The air pressure measuring sensor can be arranged in the front cavity of the earphone, and is used for measuring the change condition of air pressure in the human ear when a sine wave frequency sweeping signal is input into the human ear, namely measuring corresponding different air pressure values under different frequency values, and generating a first air pressure curve in the auditory canal of the ear, which is currently worn by the first user, of the first user according to the corresponding relation between all the frequency values and the air pressure values. In addition, in the frequency response curve, the frequency response, i.e., the frequency response, is a phenomenon in which when an audio signal outputted at a constant voltage is connected to a system, the sound pressure generated by a sound box increases or attenuates with the change in frequency, and the phase changes with the frequency, and the change relationship (change amount) between the sound pressure and the phase with respect to the frequency is referred to as the frequency response, and the unit is decibel (dB). The frequency characteristics of a sound box are often described by a frequency response curve, i.e., a frequency response curve, the ordinate of which represents a sound pressure level (dBSPL), the abscissa of which represents a frequency (Hz), and the scale of the abscissa is logarithmic for recording convenience, and the ordinate is linear, and the frequency response curve of a general product represents the auditory effect of a user on the product. For the pressure curve, the abscissa of the pressure curve is frequency (Hz) and the ordinate is pressure (dBPa). And then acquiring a pre-stored simulated head standard air pressure curve and a simulated head standard frequency response curve. The simulated head standard air pressure curve and the simulated head standard frequency response curve can be generated after passing through a preset tuning processing flow, specifically, sine wave frequency sweeping signals in a specified frequency range can be played in ears of the simulated head, and then acoustic engineers perform preset tuning processing on an original frequency response curve generated according to the sine wave frequency sweeping signals based on related testing equipment to generate the simulated head standard air pressure curve and the simulated head standard frequency response curve. The simulated human head standard air pressure curve is obtained by measuring according to the simulated human head standard frequency response curve by an air pressure measuring sensor. In addition, a same simulated human head standard air pressure curve and a same simulated human head standard frequency response curve can be arranged for the left ear and the right ear, namely the simulated human head standard air pressure curve can be simultaneously suitable for the left ear and the right ear, and the simulated human head standard frequency response curve can be simultaneously suitable for the left ear and the right ear. Or, a simulated human head standard air pressure curve corresponding to each other is respectively arranged for ears on different sides, a simulated human head standard frequency response curve corresponding to each other is also respectively arranged for ears on different sides, namely, a corresponding simulated human head left ear standard air pressure curve and a corresponding simulated human head standard left ear frequency response curve are separately arranged for left-side ears, and a simulated human head right ear standard air pressure curve different from the left-side ears and a corresponding simulated human head standard right ear frequency response curve are separately arranged for right-side ears. And finally, calculating a first frequency response curve corresponding to the first user according to the first air pressure curve, the simulated head standard air pressure curve and the simulated head standard frequency response curve. The first frequency response curve may be obtained from a curve correlation relationship among a first air pressure curve, the simulated head standard frequency response curve, and the first frequency response curve. In addition, a curve correlation calculation formula corresponding to the curve correlation relationship is preset, and the first frequency response curve can be calculated through the curve correlation calculation formula. Further, if the wearing action that the user wears the earphones on the ears on the two sides is detected at the same time, the measurement of the air pressure curve in the ear canal of each ear is executed at the same time in a synchronous mode, and the first frequency response curves corresponding to the ears on the two sides are calculated at the same time according to the acquired simulated human head standard air pressure curve and the simulated human head standard frequency response curve. In the embodiment, the sine wave frequency sweep signal in the specified frequency range is played in the ear of the first user currently wearing the earphone, then the air pressure measurement sensor is used for acquiring the first air pressure curve in the auditory canal of the ear of the first user currently wearing the earphone, and then the first frequency response curve corresponding to the first user is conveniently and quickly calculated according to the acquired pre-stored simulated human head standard frequency response curve and the simulated human head standard air pressure curve, so that the intelligent adjustment of the sound quality of the earphone is realized. The obtained first frequency response curve is correspondingly generated according to the change condition of the air pressure of the ear canal after the first user wears the earphone, so that the first frequency response curve can meet the high-quality requirement of the first user on the sound quality, the optimal auditory effect can be achieved when different users use the earphone, and the user experience is effectively improved.

And for the right ear, a simulated human head right ear standard air pressure curve different from the left ear and a corresponding simulated human head standard right ear frequency response curve are corresponding. In addition, the specified simulated human head standard frequency response curve corresponding to the specified side ear is generated by playing the sine wave frequency sweep signal in a specified frequency range in the specified side ear of the simulated human head and performing preset tuning processing on an original frequency response curve generated according to the sine wave frequency sweep signal by an acoustic engineer based on related test equipment. And the specified simulated human head standard air pressure curve corresponding to the specified side ear is obtained by measuring according to the specified simulated human head standard frequency response curve by an air pressure measuring sensor.

Further, in an embodiment of the present application, after the step S400, the method includes:

s4000: generating first tag information corresponding to the first frequency response curve, wherein the first tag information includes first user information of the first user and ear information corresponding to a designated lateral ear of the first user;

As described in steps S4000 to S4002, after the first frequency response curve corresponding to the designated ear of the first user is calculated, the first marker information corresponding to the first frequency response curve is generated, and the first frequency response curve and the first marker information are packed and stored, so that the stored first frequency response curve can be directly called later. Specifically, after the step of calculating the first frequency response curve corresponding to the ear of the first user on the designated side by calling a preset curve correlation calculation formula according to the first air pressure curve, the designated simulated head standard air pressure curve and the designated simulated head standard frequency response curve, the method includes: first, first mark information corresponding to the first frequency response curve is generated. The first tag information includes first user information of the first user and ear information corresponding to a specified side ear of the first user. In addition, the first user information at least comprises a user name or a user id name of the first user, and the first user information can be extracted and obtained by collecting related voice data input by the first user. The ear information includes a left ear or a right ear, and for example, when the designated ear is a left ear, the corresponding ear information is the left ear, and when the designated ear is a right ear, the corresponding ear information is the right ear. After the first frequency response curve is generated, the first frequency response curve and the first mark information corresponding to the first frequency response curve are packaged and stored. The above-mentioned packaging storage may be understood as that the first frequency response curve and the first flag information are both placed in the same storage location in the headset to form a unique mapping relationship between the first frequency response curve and the first flag information, for example, they may be placed in a newly created folder with a file name of the first user's frequency response curve.

Further, in an embodiment of the present application, after the step S4002, the method includes:

s4003: judging whether wearing action of a second user wearing the earphone in a specific side ear is detected, wherein the specific side ear comprises a left side ear or a right side ear;

s4004: if the wearing action that a second user wears the earphone in the ear at the specific side is detected, second user information corresponding to the second user is obtained;

s4005: matching the second user information with user information in all pre-stored mark information, and judging whether specified user information identical to the second user information exists or not;

s4006: if the specified user information identical to the second user information exists, screening specified mark information corresponding to the specified user information from all the mark information, and judging whether specified ear information identical to the specific side ear exists in the specified standard information or not;

s4007: if the specified standard information is judged to have the specified ear information which is the same as the specified auricle, extracting specified frequency response curves corresponding to the specified user information and the specified ear information;

As described in steps S4003 to S4008, for the cases of using earphones by different users, when the designated user uses earphones for the first time, a frequency response curve corresponding to the designated ear of the designated user is generated, and the user information of the designated user and the frequency response curve corresponding to the designated user are packaged and stored. Wherein, the designated user refers to any user. If the frequency response curve of the appointed user is stored in the earphone, and the appointed user wears the earphone and uses the earphone subsequently, the frequency response curve corresponding to the appointed user can be intelligently and quickly extracted from all the stored frequency response curves, so that a calculation process of calculating to obtain the corresponding frequency response curve by adopting the curve correlation calculation formula is not required to be executed, the use intelligence of the earphone is effectively improved, and the energy consumption of the earphone is reduced. Specifically, the step of executing the first frequency response curve in the designated ear of the first user includes: first, whether wearing action of a second user wearing an earphone in a specific side ear is detected is judged, wherein the specific side ear comprises a left side ear or a right side ear. In addition, whether or not a wearing motion of the second user wearing the headphone in a specific side ear is detected may be detected by a distance sensor provided in the headphone. And if the wearing action that the second user wears the earphone in the specific side ear is detected, second user information corresponding to the second user is acquired. The second user information can be extracted and obtained by collecting the related voice data input by the second user. And then, matching the second user information with the user information in all the pre-stored mark information, and judging whether the specified user information same as the second user information exists or not. If the specified user information identical to the second user information is judged to exist, specified mark information corresponding to the specified user information is screened from all the mark information, and whether specified ear information identical to the specific side ear exists in the specified standard information is judged. For example, assume that three pieces of tag information, namely tag information a, tag information B, and tag information C are stored in the headset, and user information in the tag information a is twilight, user information in the tag information B is plumet, and user information in the tag information C is twilight. If the second user information is small and clear, the specified user information identical to the second user information exists in all the pre-stored mark information, namely the user information in the mark information A. If the specified standard information contains the specified ear information which is the same as the specified oyster cap, extracting the specified frequency response curve corresponding to the specified user information and the specified ear information. According to the above example, assuming that the ear information in the tag information a is the left ear and the specific side ear is the left ear, it indicates that the same specific ear information as the specific side ear, i.e., the left ear, exists in the tag information a. In addition, because the frequency response curve, the user information and the ear information are stored in a packaging mode, the specified frequency response curve corresponding to the specified user information and the specified ear information can be extracted according to the mapping relation of the frequency response curve, the user information and the ear information. According to the above example, if the frequency response curve a is stored in a package together with the small brightness and the left ear, the frequency response curve a, that is, the specified frequency response curve, can be extracted based on the second user information whose content is the small brightness and the specified ear information whose content is the left ear. And finally, determining the specified frequency response curve as a second frequency response curve corresponding to the specific side ear of the second user, and then directly executing the extracted second frequency response curve in the specific side ear of the second user, so that the second frequency response curve is obtained by calculating without executing the curve correlation calculation formula, the use intelligence of the earphone is effectively improved, and the energy consumption of the earphone is reduced.

In an embodiment of the present application, the earphone includes a voice module disposed in the earphone body, and step S4004 includes:

Specifically, the step of acquiring the second user information corresponding to the second user may include: firstly, the voice module is used for collecting the voice signal sent by the second user. And then, the digital voice signal is identified through the voice module to obtain corresponding voice text information, and finally, the second user information corresponding to the second user is extracted from the voice text information according to the voice text information. The voice module collects voice signals sent by a second user through a voice collecting unit in the earphone; then, the analog voice signal is converted into a digital voice signal through a voice processing unit in the earphone, a time domain signal processed by the digital signal is obtained, and voice information processed by the digital signal such as filtering is transmitted to a voice recognition unit in the earphone for voice recognition processing, so that voice text information corresponding to the voice signal is obtained. For example, when a second user sends voice information to a voice input module of an earphone, such as a microphone, the voice module converts the voice information from a frequency domain signal to a corresponding time domain signal after acquiring the voice information sent by the second user, and then performs voice recognition on the time domain signal of the voice information after digital signal processing such as digital-to-analog conversion to obtain corresponding voice text information. The voice recognition process comprises preprocessing and feature extraction aiming at the time domain signal and obtaining a voice recognition result after feature matching. In addition, the voice signal may be a keyword including only user information, such as xiaoming, prune, etc.; or a sentence containing user information, such as my is twilight, my is plumet, and so on. Further, if the voice text information corresponding to the voice signal sent by the second user is my xiao ming after the recognition processing is performed on the voice signal, the subsequent keyword extraction processing and the filtering processing of the irrelevant words can be performed on the voice text information, so that the xiao ming is extracted from the voice text information of my xiao ming, and the second user information corresponding to the second user is determined as xiao ming. In this embodiment, the voice module in the earphone is used to quickly and accurately acquire the second user information corresponding to the second user, which is beneficial to the subsequent processing flow of smoothly matching the second user information with the user information in all the pre-stored label information.
