Synchronized Multi-Device Audio Playback by Frequency Split
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often provide limited audio-visual experiences and connecting them with other devices for multi-device playback can lead to auditory direction misalignment, degrading the immersive experience.
Innovation Solution
The method involves dividing audio into parts, with the first electronic device playing the human voice and high-frequency parts and the second device playing ambient sound and low-frequency parts, ensuring synchronized playback and adjusting gains and sampling rates to optimize audio quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices are connected for audio multi-device playback, then the audio-visual experience is enhanced, but auditory direction misalignment occurs degrading the immersive experience
Solution Approach 1:
The audio signal is segmented into different frequency bands (low-frequency part and high-frequency part) which are then assigned to different electronic devices for playback. This segmentation allows each device to play a specific portion of the audio spectrum, preventing auditory direction misalignment while maintaining enhanced audio-visual experience across multiple devices.
2Reliability
If audio is divided into different parts for different devices, then synchronized playback is achieved, but system complexity increases
Solution Approach 1:
The audio signal is divided based on frequency parameter changes, where low-frequency parts are assigned to one device and high-frequency parts to another. This parameter-based division enables synchronized playback across devices while managing system complexity through a clear, objective classification criterion rather than requiring complex coordination protocols.

AI summary
Embodiments of the present disclosure provide a method for an electronic device, an electronic device, and a computer-readable storage medium. A method for a first electronic device comprises: transmitting an audio playback instruction to a second electronic device in response to detecting that the second electronic device is connected with the first electronic device, where the audio playback instruction instructs the second electronic device to play audio synchronously with the first electronic device; and playing the audio synchronously with the second electronic device, where a first part of the audio is played by the first electronic device, and a second part of the audio is played by the second electronic device.
