Fig. 6 is a schematic diagram illustrating an audio playing process according to an embodiment of the present invention, and as shown in fig. 6, audio on demand may be implemented by the following steps:
step 601: the sound box sends a target audio on-demand instruction to the sound box cloud server;
step 602: in response to the on-demand instruction of the target audio, searching target audio metadata in a cloud audio private music library and/or a cloud audio public music library by the audio cloud server;
step 603: the sound box cloud server sends a corresponding audio playing instruction based on the searched audio information of the target audio metadata;
step 604: and the sound box plays the target audio according to the audio playing instruction.
With respect to step 601:
the user transmits a request instruction of ' play XXX ' to the sound box mouth, and the request instruction can be a specific song, such as ' play Zhou Jieren ' rice fragrance '; or all audio of a certain local device, such as "play song" in hua shi mobile phone, "where the hua shi mobile phone is the user-defined device name of the local device by the user. The sound box sends the on-demand instruction to the sound box cloud server.
With respect to step 602:
in response to the on-demand instruction of the target audio, the sound box cloud server searches the target audio metadata in the cloud sound box private music library and/or the cloud sound box public music library, and specifically, if the target audio can be directly determined to be the local audio in the local device according to the on-demand instruction of the target audio, the sound box cloud server only searches the target audio metadata in the cloud sound box private music library.
For example, if the on-demand instruction of the target audio is "play a song in" hua is a mobile phone ", it may be directly determined that the target audio is an offline song in the local device (hua is a mobile phone), the speaker cloud server may associate the device ID of the local device with the device name" hua is a mobile phone "according to the device information in the cloud speaker device information base, and then the speaker cloud server searches for corresponding target audio metadata in the cloud speaker private music base according to the device ID, and establishes an audio metadata list of the audio to be played according to the searched target audio metadata.
For example, if the target audio cannot be determined to be the local audio according to the on-demand instruction of the target audio, but only includes song information (audio name, performer name), the target audio metadata is searched in the cloud speaker private music library and the cloud speaker public music library at the same time according to the song information.
With respect to step 603:
the sound box cloud server searches for target audio metadata in the public music library of the cloud sound box and the private music library of the cloud sound box at the same time, and the following different situations exist:
the first situation is as follows: if only target audio metadata are searched in the cloud sound box public music library, the sound box cloud server sends a sound box cloud playing instruction to the sound box, the sound box cloud playing instruction comprises a cloud playing address of target audio in the cloud sound box public music library, and then the sound box plays the target audio according to the cloud playing address in the sound box cloud playing instruction.
Case two: if the target audio metadata are searched in the cloud audio box private music library, the audio box cloud server determines the interest type of the target audio according to the interest type information in the target audio metadata;
the rights and interests types comprise sharing rights and exclusive rights and interests, wherein the exclusive rights and interests audio can only play the target audio through an audio playing application provided by an operator with the exclusive rights and interests, or the audio playing application designates other equipment (such as a sound box) to play the target audio according to an online audio playing address provided by the audio playing application; and the audio playing application played by the sharing rights and interests is not limited.
It should be noted that the cloud speaker public music library and the audio playing application music library are two independent music libraries, where the cloud speaker public music library is an online music database provided by a speaker operator, and the audio playing application music library is an online music database provided by a three-party application (e.g., QQ music and internet music). In addition, the public music library and the music library of the audio playing application of the cloud sound box can be the same music library, namely, the public music library is a music online music library.
If the interest type of the searched target audio metadata is the sharing interest, the sound box cloud server sends a sharing interest audio playing instruction to the sound box, the sharing interest audio playing instruction comprises a local playing address of the target audio, and then the sound box plays the target audio according to the local playing address in the sharing interest audio playing instruction.
