Multi-Speaker Audio Playback Synchronization via Guided Signal Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio playback devices struggle to provide rich audiovisual experiences due to limited performance and synchronization issues between multiple devices, leading to sound delays and asynchrony when playing audio signals.
Innovation Solution
A method for connecting multiple audio playback devices with an audio acquisition device to synchronize audio playback by using connection and packet guiding information, adjusting audio signals based on device characteristics, and ensuring even device arrangement for reduced sound delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple audio playback devices are connected to provide rich audiovisual experience, then audio playback quality and flexibility are improved, but synchronization between devices deteriorates and sound delay increases
Solution Approach 1:
The system divides the audio signal transmission into two paths: a first audio signal transmitted through the audio acquisition device to all playback devices, and a second audio signal transmitted through the first playback device to the second playback devices. This segmentation allows each path to be optimized independently for synchronization.
Solution Approach 2:
The first playback device acts as an intermediary between the audio acquisition device and the second playback devices. It receives the first audio signal, processes it into a second audio signal, and transmits it to the second playback devices, ensuring synchronized playback across all devices.
2Area of stationary object
If audio signal is processed through audio acquisition device and multiple playback devices, then audio playback coverage is improved, but sound delay increases beyond perceptible threshold
Solution Approach 1:
The system establishes connection information and audio signal transmission paths in advance before audio playback begins. The audio acquisition device and playback devices pre-sync their connection parameters, ensuring that when audio playback starts, all devices are ready to play synchronously without perceptible delay.
Solution Approach 2:
The system dynamically adjusts audio signal transmission based on device characteristics and connection status. The first playback device dynamically processes the first audio signal into a second audio signal tailored for the second playback devices, optimizing playback timing and reducing delay.

AI summary
One or more embodiments of the present disclosure provide a method for an audio playback device, an audio playback device, an audio playback system, and a computer-readable storage medium, where the method for a first audio playback device includes: connecting with an audio acquisition device and at least one second audio playback device; sending connection information of the first audio playback device with the audio acquisition device to the at least one second audio playback device for the second audio playback device to receive, based at least on the connection information, an audio acquisition signal sent by the audio acquisition device; receiving the audio acquisition signal sent by the audio acquisition device; and playing first audio corresponding to the audio acquisition signal synchronously with the at least one second audio playback device.
