Movable Headset Speakers for Accurate Spatial Audio Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current headset technologies do not adequately provide a full audio experience for users, particularly in terms of spatial audio, due to limited speaker positions and fixed sound directionality, leading to reduced sound quality and immersive experience.
Innovation Solution
A headset with movable speakers that can be actuated to specific locations based on sound data, using magnetically actuated mechanisms or other mechanical means, to enhance spatial audio and provide a more immersive sound experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If physical speakers are limited to fixed positions on the device, then device structure is simplified and manufacturing is easier, but spatial audio accuracy and directional sound quality deteriorate
Solution Approach 1:
The patent implements movable speakers that can dynamically change their positions on the headset device. The speakers are coupled to the headset body through movable couplings, allowing them to be repositioned to different locations. This dynamic positioning capability enables accurate spatial audio rendering while maintaining a relatively simple overall device structure, as the speakers can be moved to optimal positions rather than requiring complex fixed-position multi-speaker arrays.
2Measurement precision
If more speakers are added to provide better spatial audio coverage, then sound quality and spatial awareness improve, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent employs a small number of speakers that can serve multiple spatial positions through movable couplings. These speakers can be repositioned to different locations on the headset to provide comprehensive spatial audio coverage. This multi-functional approach allows a limited number of speakers to fulfill the role of what would traditionally require many fixed-position speakers, thereby reducing device complexity while maintaining high spatial audio quality.
3Device complexity
If speakers are positioned on the sides of the device only, then device structure is simplified, but sound directionality and immersive experience are limited
Solution Approach 1:
The movable coupling mechanism enables speakers to be dynamically repositioned from fixed side positions to various locations on the headset, including front, back, and top positions. This dynamic adaptability allows the speaker system to provide comprehensive spatial sound coverage in three-dimensional space, enhancing the immersive experience while avoiding the need for complex pre-configured multi-position speaker assemblies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The movable speakers dynamically adjust to desired sound locations, improving sound quality and immersion by accurately positioning audio in three-dimensional space, enhancing the overall audio experience.
Implementation Method 1
the body may include plural magnet portions disposed about the body and to actuate the headset includes actuating at least one magnet portion of the plural magnet portions adjacent the corresponding headset location
Data Source
AI summary
A headset is provided that includes a body configured to secure to a head or neck of a user, and plural movable speakers movably coupled within the body. The headset also can include a memory to store executable instructions and one or more processors. When implementing the executable instructions, the one or more processors can be configured to obtain sound data related to plural sounds, determine a headset location for each sound of the plural sounds, and actuate the headset to move at least one movable speaker of the plural movable speakers to a corresponding headset location based on the sound data.
