It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1a shows a flowchart of a control method for a playback device according to an embodiment of the present invention, where the method of this embodiment may be executed by a control apparatus of the playback device, the apparatus may be implemented by hardware and/or software, and the apparatus may be disposed inside the playback device as a part of the playback device.
As shown in fig. 1a, the method for controlling a playback device provided in this embodiment includes the following steps:
step 101, receiving a volume synchronization message sent by a mobile terminal, wherein the volume synchronization message comprises a first current volume of the terminal.
The mobile terminal sends a volume synchronization message to the playing device, and the playing device receives the volume synchronization message. And the volume synchronization message at least comprises a first current volume of the current mobile terminal.
The mobile terminal in this embodiment includes a mobile phone, a tablet computer, a notebook, a main sound box, or other devices. The playing device comprises a sound box, a slave sound box, a power amplifier device, a mobile phone, a television, a tablet computer or a notebook computer.
And 102, acquiring a first proportion of the first current volume in a first volume adjusting range of the mobile terminal.
The proportion is the proportion of the current volume in the volume adjustment range, namely the proportion of the difference value of the current volume from the volume adjustment range to the current volume in the volume adjustment range.
the first volume adjustment range of the mobile terminal may be included in the volume synchronization information, sent to the playback device by the mobile terminal, or pre-stored in the playback device. The first volume adjusting range of the mobile terminal is A-B, A is the minimum adjustable volume of the mobile terminal, and B is the maximum adjustable volume of the mobile terminal. For example, fig. 1b is a schematic diagram illustrating volume adjustment of a playback device according to an embodiment of the present invention. As shown in fig. 1B, if a is 0, B is 16, and the first current volume V0 is 4, the first occupancy 4/16 is 25%.
and 103, determining a second current volume of the current playing device according to the first proportion, so that the second proportion of the second current volume in a second volume adjusting range of the current playing device is the same as the first proportion.
It is understood that the difference between the first ratio and the second ratio in the present embodiment is within the set error range, i.e., the two ratios are considered to be the same. The setting error range may be set to a smaller range.
and the second volume adjusting range of the playing device is C-D, C is the minimum adjustable volume of the playing device, and D is the maximum adjustable volume of the playing device. As shown in fig. 1b, if C is 0, D is 32, and the first percentage is 25% as in the above example, the second percentage of the second current volume within the second volume adjustment range should also be 25%, i.e. the second current volume V1 is 8.
generally, the volume adjustment ranges of the mobile terminal and the playing device are different, for example, the volume adjustment range of the mobile phone of the mobile terminal is generally only 0-16, the volume adjustment range of the sound box of the playing device is 0-100, and if the volume of the sound box is adjusted simply according to the volume change range of the mobile phone, the volume of the sound box becomes very small and only changes within the range of 0-16. In this embodiment, when the volume of the playback device is controlled according to the volume of the mobile terminal, the second current volume of the playback device is set by setting the first proportion of the first current volume of the mobile terminal in the first volume adjustment range of the mobile terminal, so that the second proportion of the second current volume in the second volume adjustment range of the playback device is the same as the first proportion, and thus the set current volume of the playback device can be matched with the volume of the actual requirement of the playback device, and the accuracy of volume control of the playback device is obviously improved.
in an embodiment, the volume synchronization message may further include the first volume adjustment range and a volume synchronization instruction. Correspondingly, the step 103 of determining, according to the first proportion, a second current volume of the current playback device may include: and after the volume synchronization message is analyzed to determine that the volume synchronization message comprises a volume same-proportion synchronization instruction, determining a second current volume of the current playing device according to the first proportion.
the volume same-proportion synchronous instruction is an instruction used for indicating that the current volume adjusting operation of the playing device is synchronous adjustment in the same proportion with the volume of the mobile terminal, so that the playing device determines the second current volume by adopting the method provided by the embodiment. If the volume synchronization message sent by the mobile terminal contains a volume same-proportion synchronization instruction, the mobile terminal can inform the playing device of adopting a volume same-proportion synchronization mode every time the mobile terminal controls the volume adjustment of the playing device, so that the problem that the volume same-proportion synchronization cannot be carried out due to the fact that the playing device cannot acquire the volume synchronization state of the playing device when the playing device is connected with the mobile terminal again after being disconnected with the mobile terminal due to self or network reasons is solved. The setting improves the efficiency and accuracy of volume synchronization of the playing device and the mobile terminal in the same proportion.
in one implementation, the determining, according to the first proportion, a second current volume of the current playback device may include: determining the minimum adjustable volume of the current playing device and the maximum adjustable volume of the current playing device according to the second volume adjusting range of the current playing device; and determining a second current volume of the current playing device according to the first ratio, the minimum adjustable volume of the current playing device and the maximum adjustable volume of the current playing device.
in one embodiment, the second current volume of the current playback device may be determined according to the following formula:
VOL1＝VOL1min+[(VOL-VOLmin)/(VOLmax-VOLmin)]*(VOL1max-VOL1min)；
The volume 1 is the second current volume, the volume 1min is the minimum adjustable volume of the current playing device, the volume is the first current volume, the volume is the minimum adjustable volume of the mobile terminal, the volume max is the maximum adjustable volume of the mobile terminal, the volume 1max is the maximum adjustable volume of the current playing device, the volume 1min is the minimum adjustable volume of the current playing device, the (volume-volume min)/(volume max-volume min) is the first proportion, and the (volume 1-volume min)/(volume 1 max-volume 1min) is the second proportion. The second current volume is simple in calculation mode and high in accuracy.
for example, if VOLmin is 0, VOLmax is 50, VOL1min is-10, and VOL1max is 90, it can be calculated according to the above formula: VOL1 is-10 when VOL is 0; VOL1 is 90 when VOL is 50; when the VOL is 40, the VOL1 is 70.
and step 104, adjusting the playing volume of the current playing device to the second current volume.
After determining a second current volume of the current playing device, adjusting the playing volume of the current playing device to the second current volume, and performing playing operation based on the second current volume.
According to the control method of the playing device provided by the embodiment, the playing device controls the current volume of the playing device to be set to the volume which meets the requirement that the second proportion of the current volume of the playing device in the volume adjusting range of the playing device is the same as the first proportion according to the current volume of the mobile terminal and the first proportion of the current volume of the mobile terminal in the volume adjusting range of the mobile terminal, so that the volume is adjusted in a linkage manner in the same proportion between the playing device and the mobile terminal, and the accuracy of volume control of the playing device is improved.

The second current volume is simple in calculation mode and high in accuracy.
step 203, sending the second current volume to the playing device, so that the playing device adjusts the playing volume to the second current volume.
for example, if the volume up key of the mobile terminal is triggered once, as shown in fig. 1b, the volume of the mobile terminal is increased from 4 to 5, i.e. the first current volume of the mobile terminal is 5 at this time, which is known from 5/16 to 10/32, then the volume of the playback device should be increased from 8 to 10, i.e. the second current volume of the playback device is determined to be 10. And sending the second current volume to the playing device, so that the playing device performs playing operation at the volume of 10.
according to the control method of the playing device, when the mobile terminal detects that the volume synchronization event is triggered, the first current volume of the current mobile terminal is obtained according to the first proportion in the first volume adjusting range of the current mobile terminal, the second current volume of the playing device is generated according to the first proportion, so that the second current volume is the same as the first proportion in the second volume adjusting range of the playing device, the second current volume is sent to the playing device, the playing volume is adjusted to the second current volume by the playing device, the volume is adjusted in a linkage mode in the same proportion between the playing device and the mobile terminal, and the accuracy of volume control of the playing device is improved.
