Movable Headset Sound Routing for Immersive Audio and Voice Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices, such as VR and AR glasses, lack the ability to facilitate voice sharing among users in private or interactive scenarios, as they primarily rely on external headsets for immersive sound experiences.
Innovation Solution
A wearable device with a movably disposed headset that can switch between two positions, allowing it to output sound at different powers through integrated sound outlets, either loud for speaker mode or closer to the ear for receiver mode, using a connecting rod and magnetic components for easy switching and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the wearable device connects to an external headset for immersive sound experience, then the sound quality is improved, but the device cannot achieve voice sharing functionality
Solution Approach 1:
The patent merges the functions of immersive sound delivery and voice sharing into a single integrated system. The device body includes both a sound guide channel for immersive sound and a speaker for voice sharing, while the headset can connect to either the sound guide channel or the speaker depending on the usage scenario, eliminating the need for separate devices for different functions.
Solution Approach 2:
The headset is designed with universal functionality to work in multiple modes: it can connect to the sound guide channel for immersive sound experience or connect to the speaker for voice sharing. This multi-functionality allows a single device to adapt to different usage scenarios, resolving the contradiction between specialized sound quality and versatile adaptability.
2Adaptability or versatility
If the headset outputs sound at high power for voice sharing, then the voice sharing capability is improved, but the immersive sound experience is reduced
Solution Approach 1:
The system dynamically adjusts the sound output path and power based on the usage scenario. When voice sharing is needed, the headset connects to the speaker which outputs sound at high power. When immersive sound experience is needed, the headset connects to the sound guide channel which delivers sound at optimized power levels through the acoustic channel, providing dynamic adaptation to different functional requirements.
Solution Approach 2:
Different parts of the sound output system have specialized local qualities: the speaker is optimized for high-power voice sharing with directional sound projection, while the sound guide channel is optimized for immersive sound delivery through acoustic coupling. The headset can selectively connect to the appropriate component based on the required function, allowing each component to operate at its optimal performance characteristics.
3Device complexity
If the headset is fixed on the device body, then the structure is simplified, but the device cannot switch between immersive sound mode and voice sharing mode
Solution Approach 1:
The headset is designed with movable connection capability, allowing it to dynamically switch between different connection states: connected to the sound guide channel for immersive sound mode or connected to the speaker for voice sharing mode. This dynamic reconfigurability enables mode switching without requiring complex permanent structural arrangements for each mode.
Solution Approach 2:
The sound output system is segmented into distinct functional paths: the sound guide channel path and the speaker path. The headset can selectively connect to either path, creating modular functionality that simplifies the overall structure while enabling mode switching. Each segment is independently optimized for its specific function, and the selective connection mechanism provides versatility without excessive complexity.

AI summary
A wearable device and a control method for a wearable device are provided. The wearable device includes a device body and a headset. The device body is provided with a sound guide channel having a first sound outlet and a docking port. The headset is movably disposed on the device body, and is configured to switch between a first position and a second position relative to the device body. The headset is provided with a second sound outlet. When the headset is at the first position, the second sound outlet is connected to the docking port, and the headset outputs sound through the first sound outlet at first power. When the headset is at the second position, the second sound outlet is separated from the docking port, and the headset outputs sound through the second sound outlet at second power. The first power is greater than the second power.
