[0064] In order to make the above-mentioned purposes, features and advantages of the application more apparent and understandable, the technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application.

[0065] Embodiment one

[0066] The embodiment of the present application provides a volume optimization method. In a first embodiment of the volume optimization method, with reference to Figure 1 , the volume optimization method comprises the following steps.

[0067] In step S10, a standard volume curve corresponding to each user age range of a playing device at a standard listening distance is acquired.

[0068] In the embodiment, it should be noted that the user age range is a possible age range of a user, and the user age range can be an age range of every 5 years from 0 to 100 years old, or an age range of every 10 years from 0 to 100 years old.

[0069] For example, step S10 comprises the following steps: acquiring the standard listening distance according to the playing device; and acquiring a correlation curve between a playing volume and a sound intensity of the playing device corresponding to each user age range at the standard listening distance.

[0070] As an example, when the playing device has a display screen, the step of acquiring the standard listening distance comprises the following steps: acquiring the size of the display screen; and determining the standard listening distance of the playing device corresponding to a preset user viewing experience according to 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 m is selected as the standard listening distance; and when the size of the display screen is 65 inches, 3.5 m is selected as the standard listening distance. The preset user viewing experience is a pre-set experience effect of a user viewing the display device, and the preset user viewing experience can be obtained by scoring the user viewing experience at different listening distances, and the listening distance with the best score is taken as the standard listening distance.

[0071] As an example, when the playing device does not have a display screen, the step of acquiring the standard listening distance comprises the following steps: when the playing device does not have a display screen, the standard listening distance of the playing device is determined according to the sound effect of a loudspeaker of the playing device under the preset user listening experience.

[0072] In step S10, the step of acquiring the standard volume curve of the playing device at each user age comprises the following steps.

[0073] In step S11, each user age range is acquired.

[0074] Step S12, according to the playing device in the standard listening distance and each user age group, the corresponding decibel value of the different volume, draw the relationship between the playing volume and the sound intensity curve, get each user age group corresponding standard volume curve.

[0075] Exemplarily, steps S11 to S12 include: obtaining each user age group; playing an audio test signal through a playing device, determining different volumes of playing the audio test signal, measuring the corresponding decibel value of each volume through a sound pressure meter at the standard listening distance and each user age group, drawing the relationship between the playing volume and the sound intensity curve, and obtaining the standard volume curve corresponding to each user age group, wherein the audio test signal can be pink noise, which is a signal with a power spectral density inversely proportional to the frequency band; it can also be white noise, which is a random signal with a constant power wavelength spectral density.

[0076] Further, the step of obtaining the standard volume curve corresponding to each user age group includes:

[0077] determining whether the user age group meets a preset first age group, if the user age group meets the preset first age group, reducing the gain of the reference volume curve to obtain the standard volume curve corresponding to the user age group; determining whether the user age group meets a preset second age group, if the user age group meets the preset second age group, keeping the gain of the reference volume curve to obtain the standard volume curve; determining whether the user age group meets a preset third age group, if the user age group meets the preset third age group, increasing the gain of the reference volume curve to obtain the standard volume curve.

[0078] Step S20, according to the current user's age, determining the current volume curve corresponding to the current user in each standard volume curve;

[0079] Exemplarily, step S20 includes: obtaining the current user's age, according to the current user's age, obtaining the current user age group corresponding to the current user's age, and according to each standard volume curve, determining the current volume curve corresponding to the current user age group.

[0080] In step S20, the step of determining the current volume curve corresponding to the current user in each standard volume curve according to the current user's age includes:

[0081] Step S21, obtaining the current user's age and the current listening distance;

[0082] Step S22, according to the current user's age, selecting the target standard volume curve corresponding to the current user's age in each standard volume curve.

[0083] Step S23, adjusting the target standard volume curve according to the distance deviation between the current listening distance and the standard listening distance to obtain a current volume curve.

[0084] For example, steps S21 to S23 include: obtaining the age of the current user and the current listening distance; obtaining a target age segment corresponding to the age of the current user in each user age segment, and selecting a target standard volume curve corresponding to the target age segment in each standard volume curve; obtaining a distance deviation between the current listening distance and the standard listening distance, and adjusting the target standard volume curve according to the distance deviation to obtain a current volume curve, for example, when the distance deviation is greater than 0, i.e., the current listening distance is greater than the standard listening distance, the target standard volume curve is translated upward; when the distance deviation is less than 0, i.e., the current listening distance is less than the standard listening distance, the target standard volume curve is translated downward.

[0085] In step S21, the age of the current user is obtained, including:

[0086] Step A10, obtaining a region image of a region in front of the playback device;

[0087] Step A20, extracting a target image carrying face information from the region image;

[0088] Step A30, performing age prediction on the current user according to an age prediction model and the target image to obtain the age of the current user.

[0089] For example, steps A10 to A30 include: obtaining a region image of a region in front of the playback device; performing background and foreground separation processing on the region image to obtain background data and foreground data, determining whether there is face information in the foreground data, if there is face information in the foreground data, taking the foreground data as a target image; if there is no face information in the foreground data, returning to execute the step of obtaining a region image of a region in front of the playback device; inputting the target image into an age prediction model, extracting face features of the face information through the age prediction model, and outputting age data as the age of the current user according to the face features, wherein the background and foreground separation method can be an optical flow algorithm, a low-rank decomposition, or a mixture Gaussian modeling, the face features are used to represent age-related feature information, and the feature information can be the number of wrinkles on the face or the turbidity of the iris of the eye.

[0090] As an example, when the playing device does not have a camera, the step of acquiring the age of the current user can also be: acquiring the age of the current user set by the user.

[0091] Step S30, according to the playing content of the playing device, the current volume curve is corrected to adjust the volume of the playing device.

[0092] Exemplarily, step S30 includes: acquiring the playing content corresponding to the playing device, and correcting the current volume curve according to the playing content to adjust the volume of the playing device.

[0093] The embodiments of the present application provide a volume optimization method. Compared with the method of adjusting the volume curve for fixed users and fixed use scenarios in the prior art, the embodiments of the present application acquire the standard volume curve corresponding to each user age range of the playing device at a standard listening distance; determine the current volume curve corresponding to the current user from the standard volume curves according to the age of the current user; and correct the current volume curve according to the playing content of the playing device to adjust the volume of the playing device, thereby realizing the adaptation of the corresponding volume through the age of the current user and the use scenario, making it possible to configure appropriate volume for the playing device, and avoiding the technical defects that the volume of the playing device is too large or too small when the use scenario or the age of the current user changes when the volume curve is adjusted for fixed users and use scenarios, thereby improving the audio playing effect.

[0094] Embodiment two

[0095] Further, based on the first embodiment of the present application, in another embodiment of the present application, the same or similar contents as the above-mentioned embodiment one can refer to the above introduction, and the following will not be described in detail. On this basis, in step S30, the playing content includes music content and video content, and the step of correcting the current volume curve according to the playing content of the playing device and the age of the current user to adjust the volume of the playing device includes:

[0096] Step S31, when the playing content is music content, the current volume curve is corrected by sound effect classification;

[0097] Step S32, when the playing content is video content, the current volume curve is corrected by content classification.

[0098] Exemplarily, the step S31 to the step S32 include: acquiring a playing content label sent by the playing device, and when the playing content label is a music content label, performing sound effect classification correction on the current volume curve; and when the playing content label is a video content label, performing content classification correction on the current volume curve.

[0099] In the step S31, the music content includes relaxing music, rock music and other music, and the step of performing overall correction on the current volume curve when the playing content is the music content includes:

[0100] In the step B10, when the music content is the relaxing music, the high sound effect gain in the current volume curve is reduced.

[0101] In the step B20, when the music content is the rock music, the low sound effect gain in the current volume curve is increased.

[0102] In the step B30, when the music content is the other music, the current volume curve is kept unchanged.

[0103] Exemplarily, the step B10 to the step B30 include: according to the use of the music, the music content is divided into the relaxing music, the rock music and the other music, when the music content is the relaxing music, the high sound effect gain in the current volume curve is reduced to enhance the effect of relaxing the user's mood, when the music content is the rock music, the low sound effect gain in the current volume curve is increased to enhance the shocking effect of the rock music, and when the music content is the other music, the current volume curve is kept unchanged.

[0104] In the step S32, the step of performing content classification correction on the current volume curve when the playing content is the video content includes:

[0105] In the step C10, the human voice and the background sound in the video content are acquired.

[0106] In the step C20, according to the contrast between the human voice and the background sound, the human voice gain in the current volume curve and the background sound gain in the current volume curve are adjusted.

[0107] In the embodiment, it is to be noted that the contrast is the volume difference between the human voice and the background sound.

[0108] Exemplarily, the steps C10 to C20 comprise: acquiring a volume of human voice and a volume of background sound in the video content; obtaining a contrast between the human voice and the background sound by subtracting the volume of human voice from the volume of background sound, if the contrast meets a preset first contrast range, increasing a human voice gain in the current volume curve and reducing a background sound gain in the current volume curve; if the contrast meets a preset second contrast range, keeping the current volume curve unchanged; and if the contrast meets a preset third contrast range, reducing the human voice gain in the current volume curve and increasing the background sound gain in the current volume curve.

[0109] As an example, when the playing content is video content, the step of performing content classification correction on the current volume curve further comprises: acquiring a volume fluctuation degree in the playing content, judging whether the volume fluctuation degree exceeds a preset volume fluctuation threshold, if the volume fluctuation degree exceeds the preset volume fluctuation threshold, adjusting front and rear volumes corresponding to the volume fluctuation to avoid that a too large volume fluctuation affects a listening experience of a user; and if the volume fluctuation degree does not exceed the preset volume fluctuation threshold, keeping the current volume curve unchanged.

[0110] The embodiment of the present application provides a volume optimization method. Compared with the method for adjusting a volume curve for fixed users and fixed use scenarios in the prior art, the embodiment of the present application acquires standard volume curves corresponding to each user age range of a playing device at a standard listening distance; determines a current volume curve corresponding to a current user from the standard volume curves according to an age of the current user; and corrects the current volume curve according to playing content of the playing device to adjust a volume of the playing device, so that a corresponding volume is adapted through the age of the current user and a use scenario, a suitable volume is always configured for the playing device, and the technical defect that the volume of the playing device is too large or too small when the use scenario or the age of the current user changes is avoided when the volume curve is adjusted for fixed users and fixed use scenarios, thereby improving an audio playing effect.
