Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0061] Example 1

[0062] The present application provides a volume optimization method. In the first embodiment of the volume optimization method of the present application, referring to Figure 1 , the volume optimization method includes:

[0063] Step S10, obtaining a standard volume curve of the playback device in a standard listening environment;

[0064] In this embodiment, it should be noted that the standard listening environment is the listening environment of the playback device at a standard listening distance and a standard number of listening obstacles; the standard volume curve is a correlation curve between the playback volume and sound intensity of the playback device in the standard listening environment.

[0065] Exemplarily, step S11 includes: obtaining a standard volume curve of the broadcasting equipment under the standard listening distance and the standard listening obstacle.

[0066] Wherein, in step S10, the standard listening environment includes a standard listening distance and a standard number of listening obstacles, and the step of obtaining a standard volume curve of the playback device in the standard listening environment includes:

[0067] Step S11, obtaining the standard listening distance and the number of standard listening obstacles;

[0068] Exemplarily, step S11 includes: obtaining the standard listening distance by measuring the distance between the sound pressure meter and the playback device; obtaining an environment picture of the playback device, inputting the environment picture into a preset target detection model to frame the obstacle area in the environment picture to obtain a rectangular target box corresponding to the obstacle area, and obtaining the number of standard listening obstacles by obtaining the number of rectangular target boxes. For example, the number of standard listening obstacles is set to 0 for convenience of calculation.

[0069] Wherein, in step S11, obtaining the standard listening distance includes:

[0070] Step A10: When the playback device has a display screen, determining the standard listening distance corresponding to the playback device under a preset user viewing experience based on a mapping relationship between the size of the display screen and the standard listening distance;

[0071] In this embodiment, it should be noted that the preset user viewing experience is a pre-set effect of the user's viewing experience of the display device. The preset user viewing experience can be scored by the user at different listening distances, and the listening distance with the best score is used as the standard listening distance.

[0072] Exemplarily, step A10 includes: when the playback device has a display screen, obtaining the size of the display screen, and determining the standard listening distance corresponding to the playback device under a preset user viewing experience based on a mapping relationship between the size of the display screen and the standard listening distance. For example, when the size of the display screen is 55 inches, 3 meters is selected as the standard listening distance; when the size of the display screen is 65 inches, 3.5 meters is selected as the standard listening distance. The preset first size threshold range is a preset size critical value for the first listening distance; and the preset second size threshold range is a preset size critical value for the second listening distance.

[0073] Step A20: When the playback device does not have a display screen, a standard listening distance corresponding to the playback device under a preset user listening experience is determined based on the speaker characteristics of the playback device.

[0074] Exemplarily, step A20 includes: when the playback device does not have a display screen, determining a standard listening distance of the playback device based on the sound effects of the speaker of the playback device and a preset user listening experience.

[0075] Step S12: plotting a correlation curve between playback volume and sound intensity based on the corresponding decibel values ​​of the playback device at different volumes at the standard listening distance and the standard number of listening obstacles to obtain a standard volume curve.

[0076] Exemplarily, step S12 includes: playing an audio test signal through a playback device, determining different volumes for playing the audio test signal, measuring the decibel value corresponding to each volume through a sound pressure meter at the standard listening distance and the standard number of listening obstacles, drawing a correlation curve between the playback volume and the sound intensity, and obtaining a standard volume curve, wherein the audio test signal can be pink noise, which is a signal with a spectrum whose power spectral density is inversely proportional to the frequency band; or white noise, which is a random signal with a constant power spectral density.

[0077] Step S20, adjusting the standard volume curve according to the deviation between the user's current listening environment and the standard listening environment to obtain a reference volume curve corresponding to the current listening environment;

[0078] Exemplarily, step S20 includes: obtaining a deviation between the user's current listening environment and the standard listening environment, converting the deviation into an adjustment value, adjusting the standard volume curve according to the adjustment value, and obtaining a reference volume curve corresponding to the current listening environment.

[0079] Wherein, in step S20, the current listening environment includes the current listening distance and the current number of listening obstacles.

[0080] The step of adjusting the standard volume curve according to the deviation between the user's current listening environment and the standard listening environment to obtain a reference volume curve corresponding to the current listening environment includes:

[0081] Step S21, adjusting the standard volume curve according to the distance deviation between the current listening distance and the standard listening distance to obtain a first adjustment curve; and / or

[0082] Exemplarily, step S21 includes: according to the distance deviation between the current listening distance and the standard listening distance, adjusting the standard volume curve to obtain a first adjustment curve. For example, when the current listening distance is greater than the standard listening distance, the standard volume curve is shifted upward; when the current listening distance is less than the standard listening distance, the standard volume curve is shifted downward.

[0083] Step S22 : adjusting the first adjustment curve according to the deviation between the current number of listening obstacles and the standard number of listening obstacles to obtain a second adjustment curve as a reference volume curve corresponding to the current listening environment.

[0084] Exemplarily, step S22 includes: performing a translation adjustment on the first adjustment curve based on a deviation between the current number of listening obstacles and the standard number of listening obstacles to obtain a second adjustment curve as a reference volume curve corresponding to the current listening environment. For example, when the current number of listening obstacles is greater than the standard number of listening obstacles, the standard volume curve is shifted upward; when the current number of listening obstacles is less than the standard number of listening obstacles, the standard volume curve is shifted downward.

[0085] Step S30 , correcting the current playback volume curve corresponding to the current listening environment according to the reference volume curve, so as to adjust the volume of the playback device.

[0086] Exemplarily, step S30 includes: modifying the current playback volume curve according to a degree of deviation between the reference volume curve and the current playback volume curve corresponding to the current listening environment, so as to adjust the volume of the playback device.

[0087] In step S30, before the step of correcting the current playback volume curve corresponding to the current listening environment based on the reference volume curve to adjust the volume of the playback device, the volume optimization method further includes:

[0088] Step B10 , plotting a correlation curve between playback volume and sound intensity based on the corresponding decibel values ​​of the playback device at different volumes in the current listening environment, to obtain a current playback volume curve.

[0089] Exemplarily, step B10 includes: playing an audio signal through a playback device, determining different volumes for playing the current audio signal, measuring the decibel values ​​corresponding to each volume using a sound pressure meter at a current listening distance and a current number of listening obstacles, and drawing a correlation curve between the playback volume and the sound intensity to obtain a current playback volume curve.

[0090] Embodiments of the present application provide a volume optimization method. Compared to the prior art method of determining a volume curve based on the speaker characteristics of a playback device and adjusting the volume of the playback device using the volume curve, the embodiment of the present application obtains a standard volume curve of the playback device in a standard listening environment; adjusts the standard volume curve based on the deviation between the user's current listening environment and the standard listening environment to obtain a reference volume curve corresponding to the current listening environment; and corrects the current playback volume curve corresponding to the current listening environment based on the reference volume curve to adjust the volume of the playback device. This achieves adaptation of the corresponding volume to the listening environment, so that an appropriate volume can always be configured for the playback device. This avoids the technical drawbacks of determining a volume curve based on the speaker characteristics of the playback device and adjusting the volume of the playback device using the volume curve, where, in an environment of the same size, the volume of the playback device is lower when the user is farther away or the environment is crowded due to many obstacles, or is higher when the user is closer or the environment is more spacious due to few obstacles, thereby improving the playback effect.

[0091] Example 2

[0092] Further, refer to Figure 2 Based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to above and will not be described in detail. On this basis, in step S30, the step of correcting the current playback volume curve corresponding to the current listening environment based on the reference volume curve to adjust the volume of the playback device includes:

[0093] Step S31, obtaining a decibel difference between a first decibel value of the same volume in the reference volume curve and a second decibel value on the current playback volume curve;

[0094] Step S32: convert the decibel difference into a corresponding DSP gain, and adjust the volume of the playback device according to the DSP gain.

[0095] In this embodiment, it should be noted that the DSP gain is used to represent the degree of debugging of the decibel difference.

[0096] Exemplarily, steps S31 to S32 include: obtaining, based on the reference curve and the current curve, a decibel difference between a first decibel value of the same volume in the reference volume curve and a second decibel value on the current playback volume curve; converting the decibel difference into a corresponding DSP gain, and adjusting the volume of the playback device according to the DSP gain. For example, when the decibel difference is greater than 0, the corresponding DSP gain is a positive value; when the decibel difference is less than 0, the corresponding DSP gain is a negative value.

[0097] Wherein, in step S32, the step of converting the decibel difference into a corresponding DSP gain includes:

[0098] Step C10: If the decibel difference is within a preset first decibel difference threshold, selecting a first conversion coefficient, and obtaining the DSP gain by calculating the product of the decibel difference and the first conversion coefficient;

[0099] Step C20: If the decibel difference is within a preset second decibel difference threshold, a second conversion coefficient is selected, and the DSP gain is obtained by calculating the product of the decibel difference and the second conversion coefficient.

[0100] In this embodiment, it should be noted that the preset first decibel difference threshold is a preset decibel difference critical value for selecting the first conversion coefficient; the preset second decibel difference threshold is a preset decibel difference critical value for selecting the second conversion coefficient.

[0101] Exemplarily, steps C10 to C20 include: if the decibel difference is within a preset first decibel difference threshold, selecting a first conversion coefficient, and obtaining the DSP gain by calculating the product of the decibel difference and the first conversion coefficient; if the decibel difference is within a preset second decibel difference threshold, selecting a second conversion coefficient, and obtaining the DSP gain by calculating the product of the decibel difference and the first conversion coefficient. For example, when the decibel difference is 1, the conversion coefficient is -4, and the DSP gain is -4.

[0102] Embodiments of the present application provide a volume optimization method. Compared to the prior art method of determining a volume curve based on the speaker characteristics of a playback device and adjusting the volume of the playback device using the volume curve, the embodiment of the present application obtains a standard volume curve of the playback device in a standard listening environment; adjusts the standard volume curve based on the deviation between the user's current listening environment and the standard listening environment to obtain a reference volume curve corresponding to the current listening environment; and corrects the current playback volume curve corresponding to the current listening environment based on the reference volume curve to adjust the volume of the playback device. This achieves adaptation of the corresponding volume to the listening environment, so that an appropriate volume can always be configured for the playback device. This avoids the technical drawbacks of determining a volume curve based on the speaker characteristics of the playback device and adjusting the volume of the playback device using the volume curve, where, in an environment of the same size, the volume of the playback device is lower when the user is farther away or the environment is crowded due to many obstacles, or is higher when the user is closer or the environment is more spacious due to few obstacles, thereby improving the playback effect.
