Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound reproduction methods in virtual scenes, such as in game applications, suffer from low accuracy and complexity, failing to ensure precise and authentic sound reproduction for multiple sound sources.
Innovation Solution
A method for sound reproduction that involves detecting a sound triggering event within a range for sound-source detection, determining the sound-source position and transmission distance, and generating the target sound based on sound-source feature information and sound curves tailored to the virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound reproduction is provided for multiple virtual objects in a virtual scene using related technology methods, then sound coverage is provided, but accuracy and authenticity of sounds reproduced cannot be ensured
Solution Approach 1:
The patent segments the virtual scene into multiple detection ranges, each associated with a specific virtual object. Each virtual object has its own sound triggering event detection mechanism, allowing independent and accurate sound reproduction for each object without complex global processing. This segmentation enables precise sound positioning while maintaining manageable complexity through modular detection and reproduction units.
2Adaptability or versatility
If operations are performed to reproduce spatial sounds via speaker for immersive audio-visual experience, then user experience is improved, but operations become complex and accuracy cannot be ensured
Solution Approach 1:
The patent establishes detection ranges and sound triggering events in advance for each virtual object before sound reproduction is needed. The terminal pre-configures the spatial relationships and detection parameters, so that when sound reproduction is required, the system can directly utilize the pre-established detection results and parameters. This preliminary action simplifies the actual sound reproduction operation while maintaining high adaptability to different virtual scenes and objects.

AI summary
A sound reproduction method and device, the method comprising: a terminal detecting a sound triggering event within a sound source detection range in a virtual scenario that corresponds to a first virtual object, wherein sound source characteristic information used for matching a sound source of a trigger sound is carried in the sound triggering event (S202); when detecting the sound triggering event, the terminal determining a sound source location at which the sound source is located according to the sound source characteristic information, and obtaining a first transmission distance between the sound source location and a first location at which the first virtual object is located (S204); the terminal determining a target sound to be reproduced of the sound source at the first position according to the first transmission distance (S206); the terminal reproducing the target sound at the first position in the virtual scenario (S208). Said method improves the accuracy of sound reproduction.
