[0062] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0063] Before introducing the specific embodiments of the present disclosure in detail, the application scenarios of the present disclosure are described as follows. The present disclosure is applied to an earphone, and the earphone may include an FB (Feed Back) microphone and an earphone speaker. Generally, an adaptive EQ (Equalizer) can be used to compensate for different leakage differences of earphone users, so that different leakages achieve similar bass effects, and hearing loss compensation can be performed for the hearing loss differences of earphone users. The principle can be to play audio with different frequencies and loudness, let the earphone user judge whether they can hear, and then generate a hearing loss curve corresponding to the individual earphone user in turn, and perform corresponding compensation to make up for the high-frequency loss caused by the hearing loss of the earphone user. However, there are certain differences in the ear canals of earphone users. This individual difference in the ear canals will cause certain differences in the audio effects generated after different earphone users resonate with the same audio, making it impossible to determine the quality of the generated audio effects. This uncertain audio effect often leads to inconsistent performance evaluations of the same earphone by earphone users, which is not conducive to improving the performance of the earphone. Moreover, there is no technical solution in the prior art to solve the defect that the individual differences in the ear canals of earphone users cause different sound effects after the sound waves emitted by the earphone resonate with the ear canals of different earphone users.

[0064] To solve the above technical problems, the present disclosure provides an audio playback method, device, storage medium, chip and earphone. When it is determined that the earphone is in the audio playback state, the audio to be played is determined from the currently played audio, and the target loudness compensation value corresponding to each target frequency point in the audio to be played is obtained from the pre-stored loudness compensation data. The loudness compensation data includes the loudness compensation values corresponding to multiple frequency points. The target standby loudness of each target frequency point in the audio to be played is determined according to the target loudness compensation value, and the audio to be played is played according to the target standby loudness of each target frequency point in the audio to be played. In this way, the target standby loudness of each target frequency point in the audio to be played can be determined according to the target loudness compensation value, so that the earphone plays the audio to be played according to the target standby loudness of each target frequency point, and the same audio effect can be generated for different earphone users, thereby eliminating the sound effect difference caused by the individual differences of earphone users, which is beneficial to further improving the performance of the earphone and enhancing the earphone user experience.

[0065] Figure 1 is a flowchart of an audio playback method shown according to an exemplary embodiment. As Figure 1 shown, the audio playback method may include the following steps:

[0066] In step 101, when it is determined that the earphone is in an audio playing state, audio to be played is determined from the currently playing audio, and a target loudness compensation value corresponding to each target frequency point in the audio to be played is obtained from pre-stored loudness compensation data.

[0067] The loudness compensation data includes loudness compensation values ​​corresponding to multiple frequency points. The target frequency point can be understood as the frequency point included in the audio to be played, and the target frequency point corresponds to the frequency in the frequency spectrum of the audio to be played. The target loudness compensation value can be understood as a compensation value used to compensate the loudness corresponding to the target frequency point in the audio to be played.

[0068] It should be noted that one audio data may include multiple different frequency points, and different audio data may include the same frequency point. For example, Figure 2 As shown, Figure 2 The present invention is a spectrum diagram of audio data according to an exemplary embodiment. The spectrum diagram uses frequency as the horizontal axis and loudness as the vertical axis. Each horizontal axis can be a frequency point. For example, frequency point 1 can indicate that the frequency of the audio to be played is 40 Hz, frequency point 2 can indicate that the frequency of the audio to be played is 450 Hz, and frequency point 3 can indicate that the frequency of the audio to be played is 720 Hz.

[0069] In this step, the target loudness compensation value corresponding to each target frequency point in the audio to be played may be obtained from the pre-stored loudness compensation data by determining a standby loudness compensation value corresponding to the target frequency point from the loudness compensation data, and using the standby loudness compensation value as the target loudness compensation value corresponding to the target frequency point.

[0070] In this step, an implementation method of determining the audio to be played from the currently playing audio may be: dividing the currently playing audio into multiple sub-audio segments under multiple time windows; and using the sub-audio corresponding to the current time window as the audio to be played.

[0071] It should be noted that the duration of the currently playing audio can be divided into multiple time windows, so that the currently playing audio can be divided into multiple sub-audios under multiple time windows, and the sub-audios corresponding to the current time window are used as the audio to be played.

[0072] For example, the duration of the currently played audio may be 3 minutes, and the duration of 3 minutes may be divided into 30 6-second time windows, and the sub-audio corresponding to the current 6-second time window may be used as the audio to be played.

[0073] Another implementation of determining the audio to be played from the currently playing audio in this step may be: using the currently playing audio as the audio to be played.

[0074] For example, the duration of the currently played audio may be 2.5 minutes, and the currently played audio may be directly used as the audio to be played.

[0075] It should be noted that the above two implementation methods of determining the audio to be played from the currently playing audio in this step can be used simultaneously. For example, if the duration of the currently playing audio is greater than 3 minutes, the currently playing audio is divided into multiple sub-audios under multiple time windows, and the sub-audios corresponding to the current time window are used as the audio to be played; if the duration of the currently playing audio is less than or equal to 3 minutes, the currently playing audio is used as the audio to be played. Loudness compensation values ​​corresponding to multiple frequency points are pre-stored in the earphone, that is, loudness compensation data. When the earphone is in the audio playing state, it can be searched from the loudness compensation data to obtain the standby loudness compensation value corresponding to the target frequency point of the currently playing audio, and the standby loudness compensation value is used as the target loudness compensation value corresponding to the target frequency point to compensate the loudness corresponding to the target frequency point.

[0076] For example, the loudness compensation value corresponding to frequency point 1 in the loudness compensation data may be 0.10 dB, and the loudness compensation value corresponding to frequency point 2 may be -0.15 dB. The loudness compensation value 0.10 dB corresponding to frequency point 1 in the loudness compensation data may be used as the target loudness compensation value corresponding to frequency point 1 in the audio to be played, and the loudness compensation value -0.15 dB corresponding to frequency point 2 in the loudness compensation data may be used as the target loudness compensation value corresponding to frequency point 2 in the audio to be played.

[0077] In step 102, a target standby loudness of each target frequency point in the audio to be played is determined according to the target loudness compensation value.

[0078] The specific implementation method of this step may be: determining the initial standby loudness of each target frequency point in the audio to be played, and determining the sum of the initial standby loudness and the target loudness compensation value for each target frequency point to obtain the target standby loudness of each target frequency point.

[0079] The initial standby loudness may be understood as the loudness without adjusting the loudness corresponding to the target frequency point in the audio to be played.

[0080] It should be noted that, when the target loudness compensation value corresponding to the target frequency is determined, the initial standby loudness of each target frequency in the audio to be played is determined, and the initial standby loudness of the target frequency is added to the target loudness compensation value corresponding to the target frequency to obtain the sum of the initial standby loudness of the target frequency and the target loudness compensation value corresponding to the target frequency, and the sum can be used as the target standby loudness of each target frequency.

[0081] Exemplarily, the target loudness compensation value corresponding to frequency point 1 in the audio to be played can be 0.10 dB, and the initial standby loudness of frequency point 1 in the audio to be played can be 1 dB. Adding the target loudness compensation value corresponding to frequency point 1 in the audio to be played to the initial standby loudness of frequency point 1 in the audio to be played, the target standby loudness of frequency point 1 in the audio to be played can be obtained as 1.10 dB. The target loudness compensation value corresponding to frequency point 2 in the audio to be played can be -0.15 dB, and the initial standby loudness corresponding to frequency point 2 in the audio to be played can be 0.90 dB. Adding the target loudness compensation value corresponding to frequency point 2 in the audio to be played to the initial standby loudness corresponding to frequency point 2 in the audio to be played, the target standby loudness of frequency point 2 in the audio to be played can be obtained as 0.75 dB.

[0082] In step 103, play the audio to be played according to the target standby loudness of each target frequency point in the audio to be played.

[0083] It should be noted that, in the case of obtaining the target standby loudness of each target frequency point in the audio to be played, the headset plays the audio to be played through the target standby loudness of each target frequency point in the audio to be played, and can generate the same loudness for different headset users.

[0084] Exemplarily, the target standby loudness of frequency point 1 in the audio to be played can be 1.10 dB, and the headset plays the loudness of frequency point 1 in the audio to be played with the target standby loudness of 1.10 dB of frequency point 1 in the audio to be played. The target standby loudness of frequency point 2 in the audio to be played can be 0.75 dB, and the headset plays the loudness of frequency point 2 in the audio to be played with the target standby loudness of 0.75 dB of frequency point 2 in the audio to be played.

[0085] The above technical solution can determine the target standby loudness of each target frequency point in the audio to be played according to the target loudness compensation value, so that the headset plays the audio to be played through the target standby loudness of each target frequency point, and can generate the same audio effect for different headset users, thereby eliminating the sound effect difference caused by the individual differences of headset users, which is beneficial to further improving the headset performance and enhancing the headset user experience.

[0086] Figure 3 is based on Figure 1 shown in the flowchart of an audio playback method according to the illustrated embodiment, as Figure 3 shown, Figure 1 The loudness compensation data described in step 101 in

[0087] S1. When the headset plays a test audio, obtain the audio loudness after the test audio resonates with the ear canal and the target loudness corresponding to the test audio.

[0088] Among them, the test audio can be the audio pre-set in the earphone, and the test audio can be a piece of music, voice, or other types of audio.

[0089] It should be noted that a test audio can be pre-set in the earphone. When the earphone plays the test audio, the FB microphone in the earphone can collect the audio loudness after the test audio resonates with the ear canal.

[0090] S2. Determine the loudness compensation value of each frequency point according to the target loudness and the audio loudness.

[0091] One implementation manner of this step can be: determine the difference between the target loudness and the audio loudness corresponding to each frequency point in the test audio; use the difference corresponding to each frequency point as the loudness compensation value of the frequency point to obtain the loudness compensation value of each frequency point in the test audio.

[0092] Another implementation manner of this step can be: generate a first curve according to each frequency point in the test audio and the target loudness corresponding to the frequency point; generate a second curve according to each frequency point in the test audio and the audio loudness corresponding to the frequency point; determine the loudness compensation value corresponding to each frequency point in the test audio according to the first curve and the second curve.

[0093] It should be noted that a first curve is generated with the frequency points in the test audio as the abscissa and the target loudness corresponding to the frequency points as the ordinate, and a second curve is generated with the frequency points in the test audio as the abscissa and the audio loudness corresponding to the frequency points as the ordinate. For the same frequency point, the difference between the ordinate of the first curve corresponding to the frequency point and the ordinate of the second curve corresponding to the frequency point can be calculated, and this difference is used as the loudness compensation value corresponding to the frequency point. In this way, the loudness compensation values corresponding to each frequency point in the test audio are obtained in turn.

[0094] Through the above technical solutions, by obtaining the audio loudness after the test audio resonates with the ear canal and the target loudness corresponding to the test audio, the loudness compensation value of each frequency point is accurately determined according to the target loudness and the audio loudness, and the loudness of each frequency point is accurately compensated, so that the earphone generates the same loudness for different earphone users, which is beneficial to further improving the performance of the earphone.

[0095] Figure 4 is a block diagram of an earphone shown according to an exemplary embodiment, as Figure 4As shown, the earphone may include: a DSP (Digital Signal Processing) chip, a DAC (Digital-to-Analog Converter), a speaker, and an FB microphone. The output end of the DSP can be connected to the speaker through the DAC. The DSP can pre-store a test audio. When the earphone plays the test audio, the DSP can send the test audio to the DAC in the form of a digital signal, so that the DAC converts the test audio into a voltage signal and sends the voltage signal to the speaker to drive the speaker to play the test audio stored by the DSP. The output end of the FB microphone is connected to the input end of the DSP. The FB microphone detects the resonant audio in the ear canal to obtain the audio loudness of the resonant audio and sends the audio loudness to the DSP. When the DSP receives the audio loudness sent by the FB microphone, it can obtain the target loudness corresponding to the test audio, determine the difference between the audio loudness of each frequency point and the target loudness corresponding to the frequency point, and use the difference as the loudness compensation value of the frequency point, so as to obtain the loudness compensation value corresponding to each frequency point in the test audio. The DSP can store the loudness compensation value corresponding to each frequency point in the test audio in the form of loudness compensation data. When the earphone is in the audio playback state, the DSP can determine the audio to be played from the currently played audio, obtain the target loudness compensation value corresponding to each target frequency point in the audio to be played from the pre-stored loudness compensation data, determine the target standby loudness of each target frequency point in the audio to be played according to the target loudness compensation value, play the audio to be played according to the target standby loudness of each target frequency point in the audio to be played, and send the target standby loudness to the speaker through the DAC, so that the speaker plays the audio to be played according to the target standby loudness of each target frequency point in the audio to be played.

[0096] It should be noted that if the FB microphone does not have the function of converting the collected audio loudness into a digital signal, the earphone may further include an ADC (Analog-to-Digital Converter). The ADC is connected between the output end of the FB microphone and the input end of the DSP and is used to convert the analog audio signal of the FB microphone into a digital audio signal and transmit the digital audio signal to the DSP.

[0097] The above technical solution can receive the audio loudness collected by the FB microphone through the DSP, determine the loudness compensation value corresponding to each frequency point in the test audio according to the audio loudness and the target loudness corresponding to the test audio, and store the loudness compensation value in the form of loudness compensation data; when the earphone is in the audio playing state, determine the audio to be played from the currently playing audio, obtain the target loudness compensation value corresponding to each target frequency point in the audio to be played from the pre-stored loudness compensation data, determine the target standby loudness of each target frequency point in the audio to be played according to the target loudness compensation value, play the audio to be played according to the target standby loudness of each target frequency point in the audio to be played, and send the target standby loudness to the speaker through the DAC, so that the speaker plays the audio to be played according to the target standby loudness of each target frequency point in the audio to be played, so that the earphone produces the same loudness and the same audio effect for different earphone users, thereby eliminating the sound effect difference caused by individual differences of earphone users, which is conducive to further improving the performance of the earphone and enhancing the user experience of the earphone.
