Detachable HMD Speaker Integration for Audio-Visual Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems often separate audio output devices from the head-mounted display unit, leading to inconsistent audio quality and user experience due to the separation of headphones from the HMD, which affects the synchronization of visual and aural content.
Innovation Solution
A display system with a detachable speaker unit that is coupleable to a head-mounted display unit, allowing audio signal processing to adjust based on the speaker's position, and includes built-in speakers for mixed reality experiences, enabling audio cues and visual indicators for sound output capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If headphones are physically separate from the head-mounted display unit, then the HMD structure remains simple and lightweight, but audio-visual synchronization deteriorates and audio quality becomes inconsistent
Solution Approach 1:
The patent combines the audio output device with the head-mounted display unit by providing a detachable speaker unit that couples to the HMD. This integration ensures that audio and visual content are synchronized and delivered from a unified system, resolving the synchronization issues caused by separate headphones while maintaining the option for detachment when not needed.
2Weight of moving object
If headphones are physically separate from the HMD, then the HMD remains lightweight, but audio quality and user experience deteriorate
Solution Approach 1:
The detachable speaker unit integrates audio functionality directly into the HMD system, providing consistent and high-quality audio output. The unit couples to the HMD to deliver synchronized audio-visual content, improving audio quality while allowing the user to detach it when audio functionality is not required, thus maintaining lightweight operation.
3Reliability
If a detachable speaker unit is integrated with the HMD, then audio-visual synchronization improves, but device complexity increases
Solution Approach 1:
The audio output device is designed as a detachable speaker unit that can be separated from the head-mounted display unit. This segmentation allows the system to achieve improved audio-visual synchronization when coupled, while avoiding increased complexity during periods when the audio unit is detached, providing flexibility in system configuration.
4Reliability
If audio signal processing adjusts based on speaker position, then audio quality improves, but system complexity increases
Solution Approach 1:
The system dynamically adjusts audio signal processing parameters such as volume, equalization, and dynamic range based on the position of the detachable speaker unit relative to the HMD. This dynamic adaptation improves audio quality by optimizing sound output for different spatial configurations, while the adjustments are automatically managed by the system to minimize user burden.
Data Source
AI summary
A display system includes a head-mounted display unit and a detachable speaker unit. The head-mounted display unit outputs visual content to a user and provides a visual pass-through of a real environment to the user. The detachable speaker unit is detachably coupleable to the head-mounted display unit for providing aural content to the user. At least one of the visual content or the aural content is changed according to a position of the detachable speaker unit relative to the head-mounted display unit.
