Master sound box, slave sound box and method for controlling synchronous playing of audio by router

Abstract

The invention relates to a master sound box. The master sound box communicates with a terminal and a slave sound box, and comprises a receiving module, a resource address sending module, a notification sending module, a first real-time playing module and an active synchronizing module, wherein the receiving module is used for receiving an audio resource address of the terminal via a streaming media transmission protocol; the resource address sending module is used for, after receiving the audio resource address of the terminal, sending the audio resource address from the sound box; the notification sending module is used for sending a notification of acquiring audio by accessing the audio resource address and playing the audio in real time to the sound box; the first real-time playing module is used for, after sending the notification to the sound box, acquiring the audio by accessing the audio resource address, and playing the audio in real time; and the active synchronizing module is used for, when the audio is played in real time, sending synchronous calibration information to the sound box. The invention further provides a slave sound box and a method for controlling synchronous playing of audio by a router. The invention achieves the effect of synchronous playing of multiple wireless sound boxes, and can be applied to classrooms, playgrounds, subways and other similar places.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a method for synchronously playing audio by a master speaker, a slave speaker and a router. Background technique [0002] In order to save the cost of laying audio lines, the current multi-speaker solution is developing towards wireless. Multiple wireless speakers play the same audio resource in the same LAN. However, due to the different network connections of each speaker in the wireless network, the wireless There is a problem of asynchronous playback between the speakers. When multiple wireless speakers are used to play at the same place at the same time, there will be a phenomenon of sound aliasing when the speakers are playing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for synchronously playing audio from the master speaker, the slave speakers and the router in view of the above-mentioned defects o...

[0002] In order to save the cost of laying audio lines, the current multi-speaker solution is developing towards wireless. Multiple wireless speakers play the same audio resource in the same LAN. However, due to the different network connections of each speaker in the wireless network, the wireless There is a problem of asynchronous playback between the speakers. When multiple wireless speakers are required to play simultaneously in the same place, there will be a phenomenon of sound aliasing when the speakers are playing.
