Directional Audio Output for Simultaneous Multi-Stream Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices can only output a single audio sound at a time, limiting their ability to provide multiple audio streams simultaneously with varying attributes and directionality, which is necessary for enhanced multimedia experiences.
Innovation Solution
An electronic device with an input unit, audio processing unit, and audio outputting unit that can process and output multiple audio streams by changing attribute values such as volume, phase, and sound pressure levels, and applying directional audio processing to simulate the spatial location of audio sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional audio output methods are used, then the device structure remains simple, but only a single audio sound can be output at a time
Solution Approach 1:
The patent segments the audio processing by separating different audio streams (first audio and second audio) into distinct processing channels. Each audio stream is independently managed with its own attribute values, allowing simultaneous output while maintaining clear organizational boundaries that prevent system complexity from becoming unmanageable.
Solution Approach 2:
The audio processing unit is designed with multi-functionality to handle multiple audio streams simultaneously. It can process different types of audio content (voice calls, music, notifications) through a unified processing framework, enabling the device to perform various audio output functions without requiring separate dedicated hardware for each function.
2Adaptability or versatility
If multiple audio streams are output simultaneously with different attributes, then audio versatility is improved, but audio processing complexity increases
Solution Approach 1:
The patent implements dynamic attribute adjustment where the first audio and second audio can have different, changeable attribute values (volume, pitch, timbre) that are modified in real-time based on playback state. This dynamic flexibility allows the system to adapt to various multimedia scenarios without requiring a completely different processing architecture for each scenario.
Solution Approach 2:
The system changes audio parameters (volume, pitch, timbre) to differentiate between multiple audio streams. By manipulating these physical parameters, the patent achieves versatile audio output capabilities where different audio content can be distinguished and controlled independently, enhancing adaptability without fundamentally changing the processing unit's structure.
3Ease of operation
If directional audio processing is applied to simulate spatial location, then user immersion is improved, but processing requirements increase
Solution Approach 1:
The patent applies local quality by assigning different spatial characteristics to different audio streams. Each audio stream can have its own directional attributes and spatial positioning, allowing the system to create immersive three-dimensional audio environments where sound sources are located at specific positions in space, enhancing user experience without requiring uniform complex processing for all audio.

AI summary
A method and an electronic device are provided for simultaneously outputting different audios with directionality. The method includes outputting a first audio, and when a request to output a second audio is detected, changing at least one attribute value of the first audio and the second audio and outputting the first audio and the second audio.
