Synchronized Multi-Device Audio Playback for Directional Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices often provide limited audio-visual experiences and suffer from auditory direction misalignment when connected to secondary devices, degrading the immersive experience.
Innovation Solution
The method involves dividing audio into parts, with the primary device playing human voice and high-frequency components and the secondary device playing ambient sound and low-frequency components, synchronized through adjustments in gain, sampling rate, and device characteristics to ensure optimal performance and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio is played through multiple electronic devices simultaneously, then the immersive audio experience is enhanced, but auditory direction misalignment occurs between devices
Solution Approach 1:
The audio signal is segmented into different frequency components (low-frequency and high-frequency parts) which are then assigned to different electronic devices for playback. This segmentation allows each device to play specific audio components, resolving the directional misalignment issue while maintaining immersive experience
Solution Approach 2:
Different frequency components of the audio signal are distributed to different devices based on their local characteristics and positions. The first device plays the first part of audio (e.g., low-frequency), while the second device plays the second part (e.g., high-frequency), creating localized audio quality optimization for each device's spatial position
2Manufacturing precision
If audio is divided and distributed to multiple devices, then sound quality is optimized for each device, but system complexity increases
Solution Approach 1:
The audio signal parameters (frequency components) are changed and transformed before distribution to different devices. By converting the audio into different frequency parts with specific parameter ranges, each device can optimize playback quality for its capabilities while the system manages complexity through parameter-based differentiation
3Adaptability or versatility
If different parts of audio are assigned to different devices, then immersive experience is improved, but synchronization difficulty increases
Solution Approach 1:
The system implements feedback mechanisms where the first electronic device receives information about the second device's playback status and adjusts its own audio output accordingly. This feedback loop ensures that different audio parts remain synchronized across devices, preventing temporal loss while maintaining immersive experience

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, where the first part of the audio includes at least one of a human voice part of the audio and a high-frequency part of the audio, and the second part of the audio includes at least one of an ambient sound part of the audio and a low-frequency part of the audio. The method for an electronic device of the present disclosure can avoid the problem of auditory direction misalignment for a user when multiple electronic devices play audio synchronously, thereby improving the immersive experience for the user.
