Referring to fig. 1, fig. 1 shows a flowchart of an audio processing method 100 for bone conduction provided by an embodiment of the present disclosure, where the method 100 is used on a server side, and includes steps S101 to S102:
step S101: and acquiring the audio signal to be compensated.
Wherein the audio signal to be compensated may comprise one or more different frequencies. It should be noted that the frequency of the embodiment of the present disclosure may include a specific frequency value, for example, 100Hz, and may also include a frequency range, for example, 100 to 150 Hz.
Step S102: and performing gain compensation on the audio signal to be compensated according to the frequency of the audio signal to be compensated to obtain a target audio signal, wherein the compensation degree corresponding to each frequency of the audio signal to be compensated is increased along with the increase of the frequency.
The inventor finds that, in the bone conduction process, the human tissue has different attenuation degrees for sound conduction of different frequencies, which causes sound distortion, so that according to the audio processing method for bone conduction provided by the embodiment of the disclosure, the audio signal is subjected to gain compensation according to the frequency of the audio signal, and the higher the frequency of the audio signal is, the higher the compensation degree for the audio in the frequency band is, and the problem of sound distortion caused by different attenuation degrees for sounds of different frequencies in the bone conduction process can be further solved. Therefore, the audio processing method provided by the embodiment of the disclosure has lower sound distortion degree and better sound transmission effect when being used for a bone conduction sound transmission mode.
In some embodiments, step S102 includes: the compensation coefficient corresponding to each frequency of the audio signal to be compensated increases with the increase of the frequency.
In some embodiments, the compensation factor is exponentially related to the frequency, and the exponentially related function is shown in equation (1):
n＝abv+c (1)
wherein n is a compensation coefficient, v is frequency, a, b and c are constants, a is greater than 0, and b is greater than 1.
Experimental studies have found that when the compensation coefficient and the frequency are in an exponential function relationship, the conducted sound is closest to the real sound, and the distortion degree is the lowest.
In some embodiments, the compensation coefficients corresponding to the frequencies may be pre-calculated according to formula (1), and a mapping relationship table between the frequencies and the compensation coefficients may be established. After the frequency of the audio signal to be compensated is obtained, the compensation coefficient corresponding to the frequency can be directly determined according to the mapping relation table, so that the audio processing efficiency is improved.
In some embodiments, the method 100 further comprises adjusting the size of a and/or b and/or c in response to a preset operation instruction. The preset operation instruction can be triggered by touch, voice and an instruction input by other wired or wireless external equipment of a user on a control preset by a user interface. Illustratively, the user can adjust the value of a and/or b and/or c by touching the user interface of the smart wearable device or by the bluetooth control device. The attenuation degree of the human body tissues to the sound conduction is different due to individuals, so according to one or more embodiments of the present disclosure, by adjusting the values of a and/or b and/or c in response to preset operation instructions, the compensation coefficients can be adjusted according to the individual differences, and the sound distortion can be reduced to the greatest extent. In some preferred embodiments, the value of the parameter b is adjustable by the user to make the compensation parameter more sensitive to changes.
In some embodiments, step S102 includes: the amplitude value of the target audio signal is the product of the amplitude value of the audio signal to be compensated and the compensation coefficient. In the embodiment of the disclosure, the amplitude value of the audio signal to be compensated may be gain compensated by the compensation coefficient, so that the loudness of the audio signal may be improved.
In some embodiments, the method 100 further comprises:
step S103: transmitting the target audio signal to a bone conduction vibration device; wherein the bone conduction vibration device is used for vibrating at the wrist of the user according to the target audio signal.

step S202: analyzing the frequency contained in the audio signal to be compensated;
step S203: determining a compensation coefficient corresponding to each frequency according to the frequency contained in the audio signal to be compensated; wherein, the compensation coefficient and the frequency are in exponential function relation;
step S204: according to the compensation coefficient corresponding to each frequency, performing gain compensation on the signal of each frequency in the audio signal to be compensated to obtain a target audio signal;
step S205: transmitting the target audio signal to the bone conduction unit.

Referring to fig. 3, the apparatus 300 includes a central processor 301, an audio processor 302, a compensation chip 303, a speaker 304, and a bone conduction vibration unit 305. The central processing unit 301 controls the audio signal to be transmitted to the audio processor 302, the audio processor 302 processes the audio signal to obtain an audio signal to be compensated, and the audio signal to be compensated can be directly played through the speaker 304 or transmitted to the compensation chip 303; the compensation chip 303 stores an audio processing algorithm for bone conduction provided according to one or more embodiments of the present disclosure, and may perform gain compensation on an audio signal to be compensated to obtain a compensated target audio signal; the compensation chip 303 transmits the target audio signal to the bone conduction vibration unit 305, and the bone conduction vibration unit 305 vibrates according to the target audio signal to conduct audio.
The audio processing method for bone conduction provided according to one or more embodiments of the present disclosure further includes: transmitting the target audio signal to a bone conduction vibration device; wherein the bone conduction vibration device is used for vibrating at the wrist of the user according to the target audio signal. The embodiment of the disclosure performs gain compensation on the audio signal according to the frequency of the audio signal, and the higher the frequency of the audio signal is, the higher the compensation degree of the audio frequency of the frequency band is, thereby overcoming the problem of sound distortion caused by different attenuation degrees when sounds with different frequencies pass through a longer conduction path of human tissues in the bone conduction process.
Accordingly, as shown in fig. 4, an embodiment of the present disclosure provides an audio processing apparatus 400 for bone conduction, including: an acquisition unit 410 and a compensation unit 420, wherein:
an obtaining unit 410, configured to obtain an audio signal to be compensated;
the compensation unit 420 is configured to perform gain compensation on the audio signal to be compensated according to the frequency of the audio signal to be compensated to obtain a target audio signal, where a compensation degree corresponding to each frequency of the audio signal to be compensated increases with an increase in the frequency.
The inventor finds that sound distortion is caused by different attenuation degrees of human tissues to sound conduction of different frequencies, so that according to the audio processing device for bone conduction provided by the embodiment of the disclosure, by performing gain compensation on an audio signal according to the frequency of the audio signal, the higher the frequency of the audio signal is, the higher the compensation degree of the audio in the frequency band is, and the problem of sound distortion caused by different attenuation degrees of sounds with different frequencies in a bone conduction process can be solved. Therefore, the audio processing device provided by the embodiment of the disclosure has lower sound distortion degree and better sound transmission effect when used in a bone conduction sound transmission mode.
For the embodiments of the apparatus, since they correspond substantially to the method embodiments, reference may be made to the partial description of the method embodiments for relevant points.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment. One of ordinary skill in the art can understand and implement it without inventive effort.
In some embodiments, the compensation coefficient corresponding to each frequency of the audio signal to be compensated increases with the frequency.
In some embodiments, the compensation factor is exponentially related to the frequency, and the exponentially related function is shown in equation (1):
n＝abv+c (1)
wherein n is a compensation coefficient, v is frequency, a, b and c are constants, a is greater than 0, and b is greater than 1.
The inventor finds that when the compensation coefficient and the frequency are in an exponential function relationship, the conducted sound is closest to the real sound, and the distortion degree is lowest.
In some embodiments, the compensation coefficients corresponding to the frequencies may be pre-calculated according to formula (1), and a mapping relationship table between the frequencies and the compensation coefficients may be established. After the frequency of the audio signal to be compensated is obtained, the compensation coefficient corresponding to the frequency can be directly determined according to the mapping relation table, so that the audio processing efficiency is improved.
In some embodiments, the apparatus 400 further comprises an adjusting unit for adjusting the size of a and/or b and/or c in response to a preset operation instruction. The preset operation instruction can be triggered by touch, voice and an instruction input by other wired or wireless external equipment of a user on a control preset by a user interface. Illustratively, the user can adjust the value of a and/or b and/or c by touching the user interface of the smart wearable device or by the bluetooth control device. The attenuation degree of the human body tissues to the sound conduction is different due to individuals, so according to one or more embodiments of the present disclosure, by adjusting the values of a and/or b and/or c in response to preset operation instructions, the compensation coefficients can be adjusted according to the individual differences, and the sound distortion can be reduced to the greatest extent. In some preferred embodiments, the value of the parameter b is adjustable by the user to make the compensation parameter more sensitive to changes.
In some embodiments, the amplitude value of the target audio signal is a product of the amplitude value of the audio signal to be compensated and the compensation coefficient. In the embodiment of the disclosure, the amplitude value of the audio signal to be compensated may be gain compensated by the compensation coefficient, so that the loudness of the audio signal may be improved.
In some embodiments, the apparatus 400 further comprises a transmission means for transmitting the target audio signal to the bone conduction vibration means; wherein the bone conduction vibration device is used for vibrating at the wrist of the user according to the target audio signal.
