Description

Control method, device and system of audio system Technical Field The present application relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a system for controlling an audio system. Background Most of the existing multi-active loudspeaker box wireless audio systems realize audio signal transmission and control based on digital wireless communication technology. Audio data is transmitted in digital data streams to a plurality of active speakers, for example, via bluetooth or wireless local area network. However, in practical application, the audio signals are usually required to be encoded, packetized, buffered and recombined, unavoidable transmission delay is easily introduced under the environment of multi-device connection or complex network, and particularly in the scene that a wireless microphone with real-time requirements is used for simultaneously sounding a plurality of active sound boxes, obvious microphone sound delay, asynchronism of sound and picture or echo phenomenon of the plurality of active sound boxes are easily generated, so that the sound expansion application with high real-time requirements is difficult to meet. On the other hand, when adjusting parameters such as volume, sound effects or reverberation for a plurality of active speakers, the prior art typically couples audio signal transmission in the same wireless link as audio parameter control. When the audio parameters need to be adjusted, the bandwidth or processing resources of the audio transmission link are often occupied, and audio interruption, jitter or delay are easily caused, so that the overall playing effect is affected. Under the scene of multiple active sound boxes, if control instructions are sent to each active sound box one by one, the adjustment of parameters of each active sound box is not synchronous due to inconsistent control time sequence, so that the listening consistency is affected. In addition, different active speakers generally have differences in hardware structure, power configuration or acoustic characteristics, and even if the same audio signals and control instructions are received, if a reasonable processing mechanism is lacking, the actual playing effect may be inconsistent, so that the overall audio experience of the multi-active speaker system is further reduced. Therefore, a new audio system control method is needed in the prior art, which can realize unified control of audio parameters of a plurality of active speakers while guaranteeing the real-time performance of audio signal wireless transmission, avoid mutual interference between audio signal transmission and parameter control, and maintain consistent playing effect under a multi-active speaker scene so as to meet the requirements of low delay and high consistency wireless sound expansion in practical application.
