And the preset database stores corresponding playing volume values of the terminal equipment when the terminal equipment is at different distances from the target object. The terminal devices may be a mobile phone, a television, a sound device, and the like, and it should be noted that, in the embodiment of the present invention, a plurality of terminal devices may be associated in advance, and specifically, may be associated by logging in the same user account, or may be connected by bluetooth or a wireless local area network, so that when a plurality of terminal devices are started simultaneously, the playing volume of the device may be coordinately controlled.
Specifically, in this step, the distance between the terminal device and the target object may be obtained by configuring a distance sensor in the terminal device and acquiring the distance between the device and the user through the distance sensor, or by configuring a camera in the terminal device, acquiring an image of the user through the camera and calculating the distance between the device and the user, or by using an indoor positioning technology based on network positioning, bluetooth positioning, and the like in the prior art, which is not described in detail in the embodiments of the present invention.
Further, for the embodiment of the present invention, a one-to-one correspondence between the distance from the user to the terminal device and the device playing volume value may be stored in the database in advance, so that when the distance between the terminal device and the user changes, the corresponding playing volume value may be directly extracted according to the correspondence, so as to facilitate adjustment when the distance between the user and the device changes, so as to stabilize the volume value received by the user.

Specifically, the step may be to call a preset detection function, and detect whether the integrated volume value calculated in the above step is within a preset volume value range.
104. And if so, adjusting each terminal device according to the playing volume value.
Specifically, the adjustment control may be performed by calling a preset function for adjusting the volume value, or the adjustment of the device volume may be realized by calling a preset interface, which is not specifically limited in the embodiment of the present invention.

Further, as a refinement and an extension of the embodiment shown in fig. 1, another volume adjustment method is provided in the embodiment of the present invention, as shown in fig. 2.
201. When the position of the target object is monitored to be changed, the distance between each terminal device and the target object is respectively obtained, and playing volume values respectively corresponding to the terminal devices are extracted from a preset database according to the distances.
And the preset database stores corresponding playing volume values of the terminal equipment when the terminal equipment is at different distances from the target object. The conceptual explanation of the terminal device in this step and the specific implementation of this step may refer to the corresponding description in step 101, and are not repeated herein.
For the embodiment of the present invention, before the step 201, the method may further include: detecting whether the distance exceeds a preset distance threshold value; if so, marking the terminal equipment as invalid terminal equipment, otherwise, marking the terminal equipment as valid terminal equipment. In this case, the step may specifically include: and extracting playing volume values respectively corresponding to the effective terminal equipment from a preset database according to the distance. It should be noted that, when the user is far enough away from the terminal device, even if the playing volume value of the terminal device is the maximum, the user still cannot receive the playing content of the terminal device, so that the device may be marked as an invalid device, and the invalid device may be set to pause playing or the playing volume value may be set to the minimum value, so as to avoid the problem of resource waste caused by the fact that the user cannot receive the playing content but the invalid device plays, thereby improving the resource utilization rate.
It should be noted that, in order to ensure that the volume value received by the user is always stable within a volume value range, for different numbers of terminal devices, even if the distance from the user is the same, the playing volume values corresponding to the respective terminal devices may be different, so that the playing volume values corresponding to different numbers of terminal devices may be stored in the database. For example, if 3 associated terminal devices are simultaneously turned on and play synchronously, the play volume value data table corresponding to the device number of 3 is extracted as shown in table 1 below. When a user moves in a space where the equipment is arranged, each piece of equipment collects and uploads the distances between the equipment and the user according to a built-in distance sensor of the equipment, wherein the distances are respectively 5 m, 1.2 m and 0.5 m, after the server receives the distances uploaded by each piece of equipment, the server detects that the distance between the equipment 1 which is 5 m away from the user and the user exceeds a preset threshold value, the equipment is marked as invalid equipment, the playing volume of the equipment is set to be 0, and meanwhile, playing volume values which respectively correspond to each piece of terminal equipment are extracted from a data table and are 30 decibels and 10 decibels.
TABLE 1
| Distance between device and target object | Playing volume value |
| 4.5～5 | 60 decibel |
| 3～4.5 | 50 decibel |
| 1～3 | 30 decibel |
| ＜1 | 10 decibel |
202. And calculating a comprehensive volume value formed by all the terminal equipment according to the playing volume values respectively corresponding to the terminal equipment.
For the embodiment of the present invention, the step 202 may include: adding the playing volume values of the terminal devices and determining the volume value obtained after the addition as the comprehensive volume value; or, calculating the comprehensive volume value according to a weighting coefficient and the playing volume value of each terminal device, wherein the weighting coefficient is determined by at least the distance and the angle between each terminal device and the target object. Further, when the weighting coefficients and the playing volume values of the respective terminal devices are used to calculate the comprehensive volume value, the weighting coefficients at least including the distance, the angle and other factors can be fitted in advance according to a large number of experiments and the like and stored, so that in the specific implementation process, the angle and the distance between the terminal devices and the user can be obtained through the angle sensor and the distance sensor which are configured in the respective terminal devices, and the weighting coefficients corresponding to the respective devices can be extracted.
It should be noted that, when a user opens a plurality of terminal devices at the same time, the volume value received by the user is the total volume value formed by the playing volume values of all the terminal devices, and therefore, before each terminal device is regulated, the comprehensive volume value formed by calculation is calculated through the extracted playing volume value of each terminal device, and corresponding measures are taken according to whether the comprehensive volume value meets the preset standard, so that the problem of time and resource waste caused by regulating and controlling the terminal devices according to the extracted volume value when the comprehensive volume value formed by a plurality of terminal devices does not meet the preset condition is solved, and the efficiency of volume regulation is improved and resources are saved.
203. And detecting whether the comprehensive volume value is within a preset volume value range.
The detailed implementation of this step may refer to the corresponding description in step 103, which is not described herein again.
204a, if yes, adjusting each terminal device according to the playing volume value.
For the embodiment of the present invention, when the integrated volume value formed by the volume values of the respective terminal devices extracted according to the distance is within the preset range, it is indicated that the volume value received by the user can be ensured to be stable if the adjustment is performed according to the extracted volume value of the respective terminal device, and therefore, in this step, the adjustment may be performed on the respective terminal devices according to the extracted play volume value. Specifically, the adjustment manner may refer to the corresponding description in step 104, and is not repeated herein in this embodiment of the present invention.
And a step 204b, which is parallel to the step 204a, of calculating a volume difference between the integrated volume value and a boundary volume value of the preset volume value range if the integrated volume value is not within the preset volume value range.
It should be noted that, when the integrated volume value calculated according to the extracted play volume values of the respective devices is not within the preset range, it indicates that the adjustment cannot be directly performed according to the extracted volume value, so that the difference between the integrated volume value and the preset range is calculated in this step, so as to correct the volume value of the terminal device. Specifically, when the integrated volume value is higher than the preset volume value range, the boundary volume value of the preset range in this step is the right boundary value, and conversely, when the integrated volume value is lower than the preset volume value range, the boundary volume value of the preset range in this step is the left boundary value. For example, if the calculated integrated volume value is 65 db and the preset volume value range is 55-60 db, the difference between the calculated integrated volume value and the boundary volume value of the preset volume value range in this step is: 65-60 db.
For the embodiment of the invention, the difference value between the comprehensive volume value and the boundary volume value of the preset volume value range is calculated so as to carry out minimum correction according to the difference value, so that the volume value received by a user is stable, the efficiency of volume adjustment is improved, and resource waste is avoided.
205b, adjusting the playing volume value of the terminal device according to the volume difference value and adjusting each terminal device by using the adjusted playing volume value.
Further, the comprehensive volume value is within the preset volume value range.
Specifically, in this step, adjusting the playing volume value of the terminal device according to the volume difference may include: determining a first terminal device closest to the target object according to the distance; and correcting the playing volume value of the first terminal device according to the volume difference value. For example, as illustrated in step 204b, if the calculated volume difference is 5 db, the terminal device closest to the terminal device may be obtained and the volume value minus 5 may be used as the final adjusted volume value of the terminal device.
It should be noted that, in this step, the nearest first terminal device is the nearest device in the valid devices, and by adjusting the device nearest to the user, the most efficient volume adjustment can be implemented, so that the volume value received by the user reaches the preset volume value range. After the device is corrected, the comprehensive volume value formed by each device is within the preset volume value range, so that each device is adjusted according to the corrected volume value, and the volume value received by a user can be ensured to be stable.
However, it should be noted that the specific implementation described in the foregoing application scenarios is only an example, and is not the only specific implementation of the embodiment of the present invention, and is only one of the optimized implementations of the method according to the embodiment of the present invention.
