In addition, it should be noted that the audio devices in this embodiment include, but are not limited to, home audio devices, movie theater audio and video devices, and public broadcasting devices capable of playing audio.

In a first embodiment, the determining the volume value of the main speaker unit to obtain the reference volume value may specifically include: determining a distance value between the main loudspeaker unit and a listening object to obtain a first distance value, and determining a reference volume value with the value in positive correlation with the first distance value. That is, in this embodiment, the volume value of the main speaker unit can be determined according to the distance value between the main speaker unit and the listening object, and the larger the distance value is, the larger the volume value of the main speaker unit is, and the two are in a positive correlation relationship, so that the volume value of the main speaker unit can be adapted to the current position of the user, and cannot be too large or too small. In this embodiment, the distance value between the main speaker unit and the listening object may be determined by using the sound intensity collected by the microphone, the distance value between the main speaker unit and the listening object may be determined by using the image information collected by the camera, the distance value between the main speaker unit and the listening object may be determined by using the positioning information collected by the positioning device based on the indoor positioning technology, and the distance value between the main speaker unit and the listening object may be determined based on the light wave or ultrasonic ranging technology. In this embodiment, for more specific processes of the above various schemes for determining the distance value between the main speaker unit and the listening object, reference may be made to corresponding contents disclosed in the following embodiments, and details are not repeated herein.

In addition, considering that when the user is far away from the main speaker unit, the attention of the user is likely not on the playing content of the audio device but busy with other things, in this case, the audio device can be controlled to stop playing the audio, so that on one hand, a relatively quiet environment can be provided for the user who is busy with other things, the attention of the user is prevented from being dispersed, and on the other hand, the intelligence degree of the audio device can be improved and the use loss of the speaker unit device can be reduced. Specifically, before determining the reference volume value with the value of the numerical value positively correlated to the first distance value, the method may further include: judging whether the first distance value is larger than a preset distance threshold value or not; if so, prohibiting the step of enabling the reference volume value with the determined value magnitude positively correlated to the first distance value. In this embodiment, the preset distance threshold may be specifically set by the user according to the actual needs of the user, and through a preset client on the audio device or the user terminal.

Specifically, in this embodiment, the volume value input by the user according to the volume preferred by the user can be acquired through the audio device or the preset client on the user terminal, and the volume value is determined as the volume value of the main speaker unit, so that the volume value of the main speaker unit can meet the actual requirement of the current user.

Specifically, in this embodiment, the volume value with the maximum frequency of use in the historical playing volume of the main speaker unit may be used as the current volume value of the main speaker unit, or all volume values in the historical time corresponding to the current time may be selected from the historical playing volume first, and then the volume value with the maximum frequency of use may be selected from the all volume values and used as the current volume value of the main speaker unit. For example, assuming that the current time is night, all volume values used by the master speaker unit in the past in the night may be selected from the historical playing volume. And then selecting the volume value with the maximum use frequency from all the volume values as the volume value of the current main loudspeaker unit. According to the scheme for determining the volume value of the main loudspeaker unit based on the current time and the historical playing volume, the main loudspeaker unit can play audio at the volume value corresponding to the current time, for example, the volume value corresponding to night or the volume value corresponding to morning can be used as the audio for the user, and the user experience is greatly improved.

It is to be understood that the above disclosure is only three specific embodiments in this example, and is not intended to limit this example, and that other possible embodiments besides the above three specific embodiments may be adopted to achieve the corresponding purposes, which is not convenient for this disclosure.

Step S12: a floating volume value of a slave speaker unit relative to the master speaker unit is determined.

In this embodiment, in order to enable different speaker units in the audio device to bring a sound-balanced experience effect to a user when playing audio, the floating volume value of the slave speaker unit relative to the master speaker unit may be determined based on a parameter capable of characterizing a distance between the different speaker units and a listening object.

In a first embodiment, the determining a floating volume value of the slave speaker unit relative to the master speaker unit may include: the method comprises the steps of collecting the intensity of sound emitted by a listening object at the same time through microphones installed in a main loudspeaker unit and a slave loudspeaker unit respectively to obtain a first sound intensity and a second sound intensity, and then determining a floating volume value with a positive correlation between the value and the difference between the second sound intensity and the first sound intensity. That is, the present embodiment may determine the floating volume value directly based on the parameter of the sound intensity that can represent the distance between the different speaker units and the listening object, and it is understood that, in the case that the first sound intensity is greater than the second sound intensity or the first sound intensity is less than the second sound intensity, the difference between the two is in positive correlation with the finally determined floating volume value, that is, the more significant the difference is, the larger the floating volume value is. Specifically, the floating volume value may be determined based on the following formula:

△Z＝Z1*(Q1/Q2-1)；

for example, assuming that the reference volume value is 100, the first sound intensity is 20 db, and the second sound intensity is 40 db, the corresponding floating volume value is-50, and then the floating volume value-50 is superimposed on the reference volume value 100, so that the volume value of the slave speaker unit is 50.

In a second specific embodiment, the determining a floating volume value of the slave speaker unit relative to the master speaker unit may include: determining the distance values between the master loudspeaker unit and the slave loudspeaker unit and a listening object respectively to obtain a first distance value and a second distance value, and then determining a floating volume value with the value in positive correlation with the difference between the second distance value and the first distance value. That is, the present embodiment may determine the floating volume value based on a parameter of a distance value that can represent distances between different speaker units and a listening object, and it is understood that, in a case where the first distance value is greater than the second distance value or the first distance value is less than the second distance value, a difference between the two values is in a positive correlation with the finally determined floating volume value.

In the third embodiment, when the user's requirement for sound balance is not particularly high, it is also possible to recognize which objects are currently placed in the room by the master speaker unit and the slave speaker unit, and then determine the floating volume value based on the recognition result. Specifically, it is possible to recognize which objects are placed in the room on the basis of the machine vision system pre-installed in the control unit of the audio device or the machine vision system pre-installed in the control unit of the audio device in the different speaker units, for example, if it is recognized that the main speaker unit is placed on the tv cabinet and the slave speaker unit is placed on the tea table, and then the general spacing between the tv cabinet and the tea table and the listening object is determined according to the historical experience data, so as to obtain two spacing parameters, for example, it is known from the historical experience data that the spacing between the tea table and the user is usually relatively small relative to the tv cabinet, if it is determined according to the historical experience data that the spacing between the tv cabinet and the user is usually 3 meters and the spacing between the tea table and the user is usually 0.5 meter, the floating volume value can then be determined from the difference between the two spacing parameters.

In the fourth embodiment, when the requirement of the user on the sound balance is not particularly high, the distance values between the master speaker unit and the slave speaker unit and the preset position point are determined to obtain a third distance value and a fourth distance value, and then the floating volume value whose value is in positive correlation with the difference between the fourth distance value and the third distance value is determined; the preset location point may be a location point automatically determined by the audio device after analyzing the path trajectory corresponding to the user in daily life and the residence time and the occurrence frequency corresponding to each trajectory point, or a location point selected by the user according to the actual preference of the user through the preset client, for example, the user may determine the location of the middle area of the sofa as the preset location point through the preset client.

It is understood that the above disclosure is only four specific embodiments in this example, and is not intended to limit this example, and besides the above four specific embodiments, other possible embodiments may also be adopted to achieve the corresponding purposes, which is not convenient for one to list here.

Step S13: and superposing the reference volume value and the floating volume value to obtain a follow-up volume value.

It can be understood that the floating volume value in this embodiment may be a positive number or a negative number, when the floating volume value is a positive number, the following volume value obtained through the above-mentioned superposition processing is greater than the reference volume value, and when the floating volume value is a negative number, the following volume value obtained through the above-mentioned superposition processing is less than the reference volume value.

Step S14: and adjusting the volume values of the master loudspeaker unit and the slave loudspeaker unit to the reference volume value and the follow volume value respectively and correspondingly.

That is, the volume value of the master speaker unit is adjusted to the reference volume value, and the volume value of the slave speaker unit is adjusted to the following volume value.

Further, considering that the volume actually perceived by the listening object changes with the ear orientation of the listening object under the condition that the volume value of the speaker unit and the distance value between the listening object and the speaker unit are constant, for example, when the ear of the listening object faces the speaker unit, the volume perceived by the listening object is the largest, and when the ear of the listening object faces away from the speaker unit, the volume perceived by the listening object is attenuated. In order to avoid the situation that the sound balance experience effect of the user may be deteriorated due to the different ear orientations of the speaker units relative to the listening object, in this embodiment, before the adjusting the volume values of the master speaker unit and the slave speaker unit to the reference volume value and the follow volume value respectively, the method may further include: determining the ear orientation of the listening subject, and then modifying the reference volume value and the follow volume value according to the ear orientation. Specifically, the ear orientation of the listening object may be determined based on a machine vision technique, then first direction information of the master speaker unit with respect to the ear orientation and second direction information of the slave speaker unit with respect to the ear orientation are determined according to the machine vision technique, then the reference volume value is corrected according to the first direction information, and the follow volume value is corrected according to the second direction information. For example, when any one of the speaker units is located in the opposite direction of the ear direction, the volume value of the speaker unit can be appropriately adjusted up, and when any one of the speaker units is located in the positive direction of the ear direction, the volume value of the speaker unit can be appropriately adjusted down or the volume value of the speaker unit can be kept unchanged, thereby being beneficial to further improving the sound equalization experience effect of the user.

It can be seen that, in the embodiment of the present application, the volume value of the master speaker unit is determined, then the volume value is used as a reference volume value, the floating volume value of the slave speaker unit relative to the master speaker unit is determined, and the reference volume value and the floating volume value are superimposed to obtain the volume value of the slave speaker unit. Therefore, in the embodiment of the application, the volume value of the master speaker unit is used as the reference volume value of the slave speaker unit, after the floating volume value of the slave speaker unit relative to the master speaker unit is determined, the reference volume value and the floating volume value are superposed, so that the volume value of the slave speaker unit can be obtained, the intervention of a user is not needed in the process, the intellectualization degree of the volume adjustment process is improved to a certain extent, the user operation is reduced, and the user experience is improved.

Referring to fig. 2, an embodiment of the present application discloses a specific volume adjustment method, including:

step S21: and determining the volume value of the main loudspeaker unit to obtain a reference volume value.

Step S22: respectively determining the position information of the main loudspeaker unit, the slave loudspeaker unit and the listening object, and accordingly obtaining first position information, second position information and third position information.

Step S24: and determining a second distance value between the slave loudspeaker unit and a listening object by using the second position information and the third position information.

That is, in this embodiment, the first distance value and the second distance value are specifically determined based on the position information of the master speaker unit, the slave speaker unit, and the listening object. It is understood that the position information of the master speaker unit, the slave speaker unit and the listening object may be position information relative to the same position point or position information in the same three-dimensional coordinate system, for example, the position information may be position information relative to a position point where a preset device is located, wherein the preset device may be one device belonging to an audio apparatus, such as the control unit a0 of the audio apparatus in fig. 3, one master speaker unit a2 and two slave speaker units a1 and A3 shown in fig. 3, and of course, the preset device may be one device independent of the audio apparatus specified by the user through the preset client. The position information may be position information in a three-dimensional space coordinate system constructed based on the entire space environment in which the speaker unit devices are located, that is, absolute position information in the space environment.

Step S25: determining a floating volume value having a magnitude that is positively correlated to a difference between the second distance value and the first distance value.

Step S26: and superposing the reference volume value and the floating volume value to obtain a follow-up volume value.

Step S27: and adjusting the volume values of the master loudspeaker unit and the slave loudspeaker unit to the reference volume value and the follow volume value respectively and correspondingly.

The specific processes of steps S25 to S27 may refer to the corresponding contents disclosed in the foregoing embodiments and the following embodiments, and are not described herein.

Referring to fig. 4, an embodiment of the present application discloses a specific volume adjusting method, including:

step S31: and determining the volume value of the main loudspeaker unit to obtain a reference volume value.

Step S32: and respectively determining relative position information among the main loudspeaker unit, the slave loudspeaker unit and the listening object and a preset device, and correspondingly obtaining first relative position information, second relative position information and third relative position information.

In a first specific embodiment, the relative position information between the main speaker unit, the slave speaker unit, and the listening object and the preset device may be determined by using the sound intensity collected by a preset microphone in the preset device. Specifically, a plurality of sound intensities corresponding to the main speaker unit, the slave speaker unit and the listening object may be determined by using a plurality of microphones installed in the preset device, and then, according to the plurality of sound intensities corresponding to the main speaker unit, the slave speaker unit and the listening object, the direction and the distance value of the main speaker unit, the slave speaker unit and the listening object with respect to the preset device may be determined accordingly.

That is, the present embodiment may mount a plurality of microphones on the preset device in advance. When the directions of the main loudspeaker unit and the slave loudspeaker unit relative to the preset device are determined, the main loudspeaker unit and the slave loudspeaker unit are controlled to play preset audio at different moments, and collects a plurality of sound intensities corresponding to each loudspeaker unit through the plurality of microphones when the loudspeaker unit plays the preset audio, it will be appreciated that in this embodiment, different microphones have different mounting positions, i.e. different orientations of the different microphones with respect to the same speaker unit, there are differences, so that the plurality of sound intensities corresponding to each speaker unit collected by the plurality of microphones are different, and by analyzing the difference between the plurality of sound intensities corresponding to each speaker unit, the direction of each speaker unit relative to the position of the plurality of microphones, that is, the direction of each speaker unit relative to the preset device, can be determined. It will be appreciated that the greater the number of microphones in the plurality of microphones, the more uniform the spatial distribution, and the more accurate the direction it will ultimately determine. In addition, the process of determining the distance value of each speaker unit with respect to the preset device may specifically include: calculating the average value of a plurality of sound intensities corresponding to each loudspeaking unit, obtaining the average sound intensity corresponding to each loudspeaking unit, and then determining the distance value between each loudspeaking unit and the preset device according to the difference between the average sound intensity corresponding to each loudspeaking unit and the volume parameter corresponding to each loudspeaking unit when playing the preset audio. In this embodiment, before each speaker unit plays the preset audio, each speaker unit may be controlled to adopt the same volume parameter, that is, each speaker unit is enabled to play the preset audio at the same volume. Secondly, the determining process of the relative position information between the listening object and the preset device may specifically include: and acquiring the sound intensity emitted by the listening object by using a plurality of microphones installed on the preset device to obtain a plurality of sound intensities corresponding to the listening object, and then determining the direction and the distance value of the listening object relative to the preset device according to the plurality of sound intensities. The process of determining the direction of the listening object with respect to the preset device is similar to the process of determining the direction of any one of the speaker units with respect to the preset device, and is not described herein again. As for the process of determining the distance value of the listening object relative to the preset device, the method specifically includes: calculating an average value of a plurality of sound intensities corresponding to the listening object to obtain an average sound intensity, and comparing the average sound intensity with an actual user sound intensity obtained based on empirical data or an actual user sound intensity collected by an intelligent device carried by the user to estimate a distance value of the listening object relative to a preset device. It is understood that the larger the difference between the average sound intensity and the user's actual sound intensity is, the larger the distance value between the listening object and the preset device is.

For example, referring to fig. 3, the audio apparatus includes two slave speaker units a1 and A3, one master speaker unit a2, and a control unit a0 placed on a tea table, and a microphone ring array including 8 microphones uniformly arranged is previously installed in the control unit a0 as shown in fig. 5. In determining the direction and distance values of each speaker unit and the listening object with respect to the control unit a0, the control unit a0 can control the slave speaker unit a1, the master speaker unit a2 and the slave speaker unit A3 to play the same preset audio, for example, to emit the "tic" sound according to the same sound emitting frequency and volume parameters, then 8 microphones are used to collect 8 sound intensities corresponding to each loudspeaker unit, the direction and distance values of each speaker unit with respect to control unit a0 are then determined based on the 8 sound intensities for each speaker unit, after that, the sound intensity emitted by the listening object can be collected by using the above 8 microphones to obtain 8 sound intensities corresponding to the listening object, then, the direction and distance value of the listening object with respect to the control unit a0 are determined based on the 8 sound intensities corresponding to the listening object.

In the second embodiment, the relative position information between the main speaker unit, the slave speaker unit, and the listening object and the preset device may also be determined by using image information collected by a preset camera. Specifically, in this embodiment, a first camera installed in the preset apparatus may be used to perform image acquisition on a spatial environment where the video device is located, to obtain a panoramic image containing depth information, identify an image area corresponding to each speaker unit in the panoramic image, to obtain a plurality of image areas containing corresponding depth information, and then determine a direction and a distance value of each speaker unit relative to the preset apparatus according to the plurality of image areas.
