Intra Aural Earpieces TRIZ Cases
- Hearing Device Speaker Membrane Holes for Acoustic Bias Control
Speaker membrane holes equalize pressure to eliminate bias, ensuring predictable acoustic properties without complex resistive members.
- Wingtip Anchor Earbud Design for Secure Fit
Curved wingtip anchor secures earbuds in varying ear shapes while integrating multifunction buttons to prevent dislodging.
- Wireless Audio Packet Retransmission for Cross-Body Signal Loss
Wireless audio devices retransmit lost packets via peer-to-peer links to resolve cross-body signal obstruction.
- Acoustic Vent and Protective Membrane for In-Ear Devices
A rear vent channel acts as a low-pass filter to attenuate high frequencies, while a flexible membrane dampens resonances to protect the microphone.
- Flexible Ear Tip with Ribs for Secure Headphone Fit
Ribs on a flexible ear tip compress against the anti-helical fold to adapt to ear anatomy, reducing discomfort during workouts.
- Wearable Sound Filter with Tunable Resonant Chamber for Tinnitus Relief
A wearable sound filter uses a resonant chamber to attenuate targeted frequencies.
- Earphone Sound Guide Tube for Low-Frequency Response
Separate sound guide tubes with damping material expand low-frequency response by nearly 100 Hz and increase loudness.
- Earphone Variable Loop Retention for Anatomical Fit
An adjustable cable loop engages the concha or antihelix to resolve retention reliability versus adaptability across diverse ear anatomies.
- Earphone Tension Diaphragm for Noise Reduction
A tension diaphragm seals the rear earphone portion to absorb air turbulence and eliminate insertion noise.
- Earphone Pressure Relief Channel for Diaphragm Protection
A dynamic pressure relief channel opens during insertion to prevent air pressure damage to the vibrating diaphragm.
- Rotatable Microphone Arm for Compact Communication Headset
A communication headset features a rotatable microphone arm that folds against the housing to reduce overall dimensions.
- Earphone Positioning Structure for Stability and Comfort
Directional stiffness in a silicone retaining structure offsets electronics weight to stabilize orientation and reduce pressure on the ear.
- Sonic Low-pressure Equalization Device for In-ear Monitor Bass Fidelity
A Sonic Low-pressure Equalization Device channels internal and ambient sound waves through a predetermined spatial volume to the ear canal stalk.
- Earmold Posterior Arch Compression for Secure Retention
A flexible elastomeric earmold uses a posterior arch to compress against the antihelix, maintaining secure positioning of the earpiece.
- Acoustic Device Separation Structure Low-Frequency Resonance
Segmenting the acoustic cavity via a separation structure with through holes enhances low-frequency resonance while maintaining compact device volume.
- In-Ear Earphone Dual Sound Path Filter Segmentation
Cylindrical separating part divides the acoustic channel into independent inner and annular outer paths for parallel transducer operation.
- Earpiece Ear Tips With Extended Neck For Acoustic Sealing
Extended neck portions enhance ear tip flexibility to resolve the trade-off between secure acoustic sealing and easy exchangeability.
- Earpiece Cradle Limits Sensor Field-of-View for Pulse Monitoring
Segmented cradle geometry blocks tangential ambient light, enabling accurate pulse monitoring without tight ear canal fit.
- Ear Supporting Structure for Stable Headphone Fit
An ear supporting structure with nested bulge portions fits specific anatomical landmarks to secure headphones.
- Earbud Adapter Segmentation for Secure Fit and Sound Quality
Segmenting retention features into a separate adapter resolves the contradiction between small earbud size and reliable dislodgment resistance.
- Air Flow Control Valve for TWS Earpiece Noise Management
Dynamic air flow control valves resolve the contradiction between blocking external noise and preventing user discomfort from trapped sound pressure.
- Angled Nozzle In-Ear Headphone Acoustic Design
Angled nozzle in-ear headphones improve sound isolation and comfort by optimizing the 0.6mm damper aperture for superior bass response.
- Earphone Cover with Variable Projection Heights
Variable height projections on detachable covers ensure concha contact for secure adhesion across diverse ear anatomies.
- Dual Speaker Earphone with Pivotable Hanger
Pivotable joints and a counterbalancing hanger bar adjust speaker orientation for stable fit, resolving complexity versus reliability trade-offs.
