Bone Conduction Transducer Hearing Devices TRIZ Cases
- Bone Conduction Speaker Dual-Plate Structure for Crack Resistance
Two spaced vibration transmission plates constrain magnetic circuit motion, reducing plate fractures and housing or coil collisions.
- Scalable Unified Audio Rendering for Low-Complexity Spatial Audio
SHC and MOA representations convert channel- and object-based audio into scene-based data, reducing rendering complexity for immersive headsets.
- Binaural Sound Clip Playback Using Pre-Convolved HRTFs
Pre-convolving sound clips with customized HRTFs enables immediate binaural playback during calls without transmitting the clips.
- Earphone Pressure Relief Hole Protection With Porous Net
Clogging at an earphone pressure relief hole can disrupt sound; a porous net maintains pressure relief while blocking contaminants.
- Vibration Transfer Function Measurement for Bone Conduction Echo Control
A microphone-based acoustic test separates air and vibration paths to measure feedback transfer and reduce echo in bone conduction hearing aids.
- Dual-Conduction Acoustic Output Device for Mid-Low Audio
Bone conduction handles high frequencies while independent air conduction fills the mid-low gap, reducing vibrations and sound leakage in wearables.
- Bone Conduction Earphone Rib Reinforcement to Reduce Sound Leakage
Reinforcing ribs divide the fixing portion into rigid and flexible zones, reducing sound leakage while preserving wearing comfort.
- Speaker Housing Acoustic Interference for Suppressing Sound Leakage
Bone conduction speaker housing vibrations can leak sound; guided-wave interference reduces leakage amplitude and supports user privacy.
- Oral-Cavity Vocalization Device With Rear Passage for Explosive Sounds
An intraoral diaphragm and passage redirect recorded sound to the rear oral cavity, supporting explosive consonant articulation.
