In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Figure 1a shows a flow chart of a method for controlling a playback device provided by an embodiment of the present invention. The method of this embodiment can be executed by a control device for a playback device, and the device can be implemented by means of hardware and/or software. , the apparatus may be set inside the playback device as a part of the playback device.

As shown in Figure 1a, the method for controlling a playback device provided in this embodiment includes the following steps:

Step 101. Receive a volume synchronization message sent by a mobile terminal, where the volume synchronization message includes a first current volume of the terminal.

The mobile terminal sends a volume synchronization message to the playback device, and the playback device receives the volume synchronization message. Wherein, the volume synchronization message includes at least the first current volume of the current mobile terminal.

The mobile terminal in this embodiment includes devices such as a mobile phone, a tablet computer, a notebook, or a main speaker. Playback devices include speakers, slave speakers, power amplifiers, mobile phones, TVs, tablet computers or notebooks.

Step 102. Obtain a first proportion of the first current volume within a first volume adjustment range of the mobile terminal.

The proportion is the proportion of the current volume within the volume adjustment range, that is, the proportion of the difference between the current volume from the beginning of the volume adjustment range to the current volume within the volume adjustment range.

Wherein, 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 adjustment range of the mobile terminal is A to B, where A is the minimum adjustable volume of the mobile terminal, and B is the maximum adjustable volume of the mobile terminal. Exemplarily, FIG. 1 b shows a schematic diagram of volume adjustment of a playback device provided by 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, then the first proportion 4/16 is 25%.

Step 103. Determine the second current volume of the current playback device according to the first ratio, so that the second ratio of the second current volume within the second volume adjustment range of the current playback device is the same as the second ratio of the current playback device. The first proportion is the same.

It can be understood that, the difference between the first ratio and the second ratio described in this embodiment can be considered to be the same if the difference is within a set error range. The set error range can be set to a smaller range.

Wherein, the second volume adjustment range of the playback device is from C to D, where C is the minimum adjustable volume of the playback device, and D is the maximum adjustable volume of the playback device. As shown in Figure 1b, if C is 0, D is 32, and as the above example, the first proportion is 25%, then the second proportion of the second current volume within the second volume adjustment range should also be 25% , that is, the second current volume V1 is 8.

Generally, the volume adjustment ranges of mobile terminals and playback devices are different. For example, the volume adjustment range of mobile terminals and mobile phones is generally only 0-16, and the volume adjustment range of playback device speakers is 0-100. To adjust the volume of the speaker, the volume of the speaker will become very small, only in 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 according to 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 ratio of the second current volume within the second volume adjustment range of the playback device is the same as the first ratio, so that the set current volume of the playback device can fit the actual volume of the playback device , obviously improving the accuracy of volume control on playback devices.

In an implementation manner, the volume synchronization message may further include the first volume adjustment range and a volume proportional synchronization instruction. Correspondingly, in step 103, determining the second current volume of the current playback device according to the first ratio may include: after parsing the volume synchronization message to determine that the volume synchronization message includes a volume synchronization instruction, according to the The first ratio is used to determine the second current volume of the current playback device.

Wherein, the volume synchronization instruction is an instruction for instructing the playback device to adjust the current volume in the same proportion as the volume of the mobile terminal, so that the playback device uses the method provided by this embodiment to determine the second current volume. If the volume synchronization message sent by the mobile terminal includes a volume synchronization command in the same proportion, it can be realized that each time the mobile terminal controls the volume adjustment of the playback device, it will inform the playback device that this time the volume is synchronized in the same proportion, so as to prevent the playback device from being affected by itself. Or after the network is disconnected from the mobile terminal, when it is connected to the mobile terminal again, it cannot know its own volume synchronization status and cannot perform volume synchronization in the same proportion. Such setting improves the efficiency and accuracy of the volume synchronization between the playback device and the mobile terminal in the same proportion.

In an implementation manner, the determining the second current volume of the current playback device according to the first proportion may include: determining the minimum possible volume of the current playback device according to the second volume adjustment range of the current playback device. Adjust the volume and the maximum adjustable volume of the current playback device; according to the first proportion, the minimum adjustable volume of the current playback device and the maximum adjustable volume of the current playback device, determine the first Two current volume.

In one embodiment, the second current volume of the current playback device can be determined according to the following formula:

VOL1＝VOL1min+[(VOL-VOLmin)/(VOLmax-VOLmin)]*(VOL1max-VOL1min);

Among them, VOL1 is the second current volume, VOL1min is the minimum adjustable volume of the current playback device, VOL is the first current volume, VOLmin is the minimum adjustable volume of the mobile terminal, VOLmax is the maximum adjustable volume of the mobile terminal, and VOL1max is the current volume. The maximum adjustable volume of the playback device, VOL1min is the minimum adjustable volume of the current playback device, (VOL-VOLmin)/(VOLmax-VOLmin) is the first proportion, (VOL1-VOLmin)/(VOL1max-VOL1min) is the second Proportion. The calculation method of the second current volume is simple and has high accuracy.

Exemplarily, if VOLmin is 0, VOLmax is 50, VOL1min is -10, and VOL1max is 90, it can be calculated according to the above formula: when VOL is 0, VOL1 is -10; when VOL is 50, VOL1 is 90; When VOL is 40, VOL1 is 70.

Step 104. Adjust the playback volume of the current playback device to the second current volume.

After the second current volume of the current playback device is determined, the playback volume of the current playback device is adjusted to the second current volume, and a playback operation is performed based on the second current volume.

The calculation method of the second current volume is simple and has high accuracy.

Step 203: Send the second current volume to the playback device, so that the playback device adjusts the playback volume to the second current volume.
