Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headsets, including bone conduction speakers, often lack privacy and may not accommodate users' physical abilities effectively, with sound quality in bone conduction technology dependent on pressure output and contact integrity between the speaker and the bone.
Innovation Solution
An adjustable bone conduction speaker system for head-mounted displays, featuring a sliding member and a protrusion member that can be adjusted along separate axes to optimize the positioning of bone conduction speakers, including locking mechanisms and sensors for precise placement and activation based on user pressure and proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bone conduction speakers are used to deliver audio, then privacy is improved and audio is delivered without blocking ear canal, but sound quality becomes dependent on pressure output and contact integrity which may not work with all users' physical abilities
Solution Approach 1:
The bone conduction speaker is mounted on an adjustable mechanism that allows dynamic repositioning along the temple piece. Users can adjust the speaker's position and angle to achieve optimal contact with their temporal bone, adapting the device to different head shapes, bone structures, and physical abilities. This dynamic adjustment capability ensures reliable audio delivery across diverse user populations.
Solution Approach 2:
The system allows users to modify the physical parameters of bone conduction speaker contact, including position, angle, and pressure applied to the temporal bone. By enabling parameter changes in how the speaker contacts the bone, the system adapts to various user anatomies and physical characteristics, maintaining reliable audio transmission without compromising sound quality.
2Reliability
If conventional speakers or headphones are used, then audio privacy is provided, but they may not accommodate users' physical abilities and may block ear canal
Solution Approach 1:
The invention extracts the audio delivery function from traditional ear canal-blocking headphones and implements it through bone conduction technology. By taking out the speaker and placing it on the temple piece to contact the temporal bone, the system eliminates the harmful effect of ear canal blocking while maintaining audio privacy and reliable delivery.
3Manufacturing precision
If bone conduction speaker contact pressure is increased to improve sound quality, then contact integrity improves, but user comfort may deteriorate
Solution Approach 1:
The adjustable mounting mechanism enables users to dynamically optimize the balance between contact integrity and comfort. Users can adjust the speaker position and pressure to achieve sufficient contact for good sound quality while maintaining comfortable wear, allowing real-time optimization of this trade-off.
Solution Approach 2:
The system allows users to modify the contact pressure parameter to find the optimal balance point. By enabling parameter changes in contact force, users can achieve adequate contact integrity for quality audio transmission without applying excessive pressure that would compromise comfort during extended wear.
