In The Ear Hearing Aids TRIZ Cases
- In-Ear Hearing Charger Coil Layout for Inductive Alignment
Sidewall coil placement improves inductive alignment in in-ear hearing chargers, enabling compact sealed devices without charging contacts.
- Ear-Worn Connector Sealing and Retention for Compact Reliability
A metal socket, gasket, and retention features create a compact hearing-device connector that resists contamination and extends service life.
- In-Ear Hearing Device Coil Layout for Inductive Charging Alignment
Sidewall-oriented receiver and transmitter coils improve inductive charging alignment in compact in-ear hearing devices despite manufacturing deviations.
- Rotatable Hearing Charger Coil for Wireless Alignment
A rotatable transmitter coil and magnets self-align with the hearing device receiver coil to improve wireless charging efficiency.
- 3D Folded Dipole Antenna Layout for In-Ear Hearing Aids
A 3D spiral folded dipole antenna uses tight in-ear housing volume more efficiently while reducing ear-shape sensitivity and improving radiation efficiency.
- Chip-Loaded Earbud Antenna Structure Without Large Ground Plane
A chip antenna and reactive loading network boost ear-worn wireless range and radiated power without a large ground plane.
- Hearing Charger Support Post for Removal Handle Alignment
A recessed support post accommodates lateral removal handles to keep ITE hearing devices aligned for secure inductive charging.
- Dual-Stiffness Antenna Layout for In-Ear Hearing Aids
A dual-stiffness antenna follows the ear canal to improve hearing-aid communication while reducing skin contact pressure and discomfort.
- In-Ear Hearing Aid Antenna with Dual-Stiffness Extraction Cord
A dual-stiffness antenna improves in-ear hearing aid communication near head obstruction while conforming to the concha for comfort and removal.
