and step S40, when the audio equipment information is judged to be matched with the self equipment information, controlling audio output or pausing the audio output according to the audio control information.
The audio output control method is executed in an audio device.
In step S10, the audio device receives the audio control packet, for example, through a network transmission protocol, but may also receive the audio control packet based on a wireless transmission protocol. The audio control data packet includes, for example, audio device information and audio control information, and certainly also includes other data packet information such as a header and a trailer of other data packets, which is not described herein again.
And the audio equipment analyzes the audio control data packet according to a corresponding data transmission protocol to obtain the audio equipment information and the audio control information. The audio device information may be unique identification information of an audio device, and is used to identify a target audio device for performing audio output control according to the audio control packet; the audio control information may include control instructions and audio output content. Specifically, the control instruction may be pause signaling or output signaling, where the pause signaling is used to control the target audio device to pause outputting audio, and the output signaling is used to control the target audio device to output audio; the audio output content may be audio file information, which may be a code or other information that uniquely identifies the audio file.
The self-equipment information is identification information which uniquely identifies the audio equipment, and at the moment, the audio equipment judges whether the analyzed audio equipment information is matched with the self-equipment information or not. If so, the audio equipment is the target audio equipment, and the audio equipment controls audio output or suspends the audio output according to the audio control information; and if not, the audio equipment does not execute corresponding operation.
Further, on one hand, the audio control information obtained by analyzing the audio control data packet by the audio device includes a pause signaling, and the device information of the audio device is matched with the audio device information obtained by analyzing the audio control data packet; at this time, the audio device is the target audio device, and the audio device suspends audio output according to the suspension signaling.

In order to understand the present embodiment more clearly, a detailed description will be given of a specific implementation process of the audio output control method of the present embodiment:
the plurality of audio devices are connected in the same network environment, and each audio device has a unique identifier and serves as own device information. For example, 5 audio devices are respectively connected to the same local area network environment in a wireless manner, and the device information of the 5 audio devices is respectively: 001. 010, 011, 100, and 101; each audio device is also respectively stored with a plurality of audio files, and each audio file is respectively provided with audio file information capable of uniquely identifying the audio file. For example, 3 audio files are stored in the audio device 001, and the audio file information of the 3 audio files is 001, 010, and 011; other audio devices also store at least one audio file, which is not described herein again; of course, the audio files stored in different audio devices may be the same, and of course, the same audio file may use the same audio file information or different audio file information on different audio devices.
And issuing audio control data packets to 5 audio devices in a routing manner, wherein the audio control data includes audio device information 001 and 011, and the audio control data packets further include first audio control information and second audio control information, wherein the first audio control information corresponds to the audio device information 001, and the second audio control information corresponds to the audio device information 011. Specifically, the first audio control information includes, for example, pause signaling, and the second audio control information includes, for example, output signaling and audio file information, and the audio file information may be 001.
Each of the 5 audio devices receives the audio control packet, and each audio device parses the audio control packet according to a corresponding wireless network protocol to obtain the audio device information 001 and 011, the first audio control information corresponding to the audio device information 001, and the second audio control information corresponding to the audio device information 011.
Each audio device matches its own device information with the audio control packet, which is obtained by parsing the audio control packet, for example, audio device information 001 and 011. Wherein, the audio device whose own device information is 001 and the audio device whose own device information is 011 are respectively successfully matched, and the other three audio devices are failed to be matched. At this time, the audio device 001 performs corresponding audio control according to the first audio control information, and the audio device 011 performs corresponding audio control according to the second audio control information.
Specifically, the first audio control information includes a pause signaling, so that the audio device 001 pauses the currently output audio according to the pause signaling, that is, the audio device 001 stops outputting the audio; the second audio control information includes an output signaling and audio file information 001, and therefore, the audio device 011 outputs an audio file corresponding to the audio file information 001 stored therein according to the output signaling.
In the implementation process, the 5 audio devices may be respectively disposed in different areas of a public place, and the 5 audio devices respectively execute the audio output control method, that is, the corresponding audio output or the audio output pause (that is, no audio output) may be performed in the different areas of the public place. The user can divide the public place into a plurality of areas, set audio equipment capable of executing the audio output control method in each area, and then control the audio equipment set in the designated area to execute the audio output control method according to the requirement so as to carry out corresponding audio control.
Preferably, the public places can be shopping malls, tunnels, air holes, squares and other public places. Wherein the tunnel may be a tunnel or tunnels on a highway segment.
