- In-Ear Hearing Aid Handle Antenna With Double-Helix RF Layout
A curved handle antenna with intertwined helical strands boosts RF length and Q factor in compact in-ear hearing aids without visible protrusion.
- In-Ear Hearing Aid Antenna Handle for Compact RF Efficiency
An arcuate double-helix handle antenna frees housing space in an in-ear hearing aid while preserving discreet RF transmission and reception.
- Ear-Worn Hearing Cable Assembly With Discrete Retention Fixing
Discrete retention members replace over-molding to lock an ear-worn hearing cable assembly against rotation and axial displacement.
- MIMO Switched-Capacitor Converter for Multi-Voltage Hearing Aids
A MIMO switched-capacitor DC-DC converter delivers simultaneous voltage rails in hearing aids, cutting IC count, PCB area, and EMI.
- MIMO Switched-Capacitor DC-DC Converter for Multi-Voltage Hearing Aids
A single MIMO switched-capacitor converter delivers simultaneous voltage rails in hearing aids, cutting converter count, EMI, and power loss.
- Ear-Worn Phased Array Antennas for 2.4 GHz Interference Rejection
Coordinated ear-worn antennas use phase shifting and beam steering to improve 2.4 GHz link quality and reject WiFi and Bluetooth interference.
- Ear-Wearable Tunnel Contacts for Reliable Cable Connection
A vent tunnel with fixed contact pins enables removable cable connection in ear-wearables while limiting debris, water intrusion, and fatigue.
- Hearing Aid Proximity Sensing for Touch-Free Switching
A built-in proximity sensor lets users switch hearing aid functions without touch, remote controls, or magnets while reducing accidental activation.
- Dual-Microphone Earpiece Voice Control for Noise Discrimination
An ambient and ear-canal microphone pair lets an earpiece distinguish the wearer's voice from background noise for clearer voice control.
- Thermal Cord Bonding in Earplug Stems for Lower-Cost Assembly
A hot tip forms a cavity in the earplug stem so the cord can be thermally bonded without adhesives, cutting assembly cost and complexity.
- Smart Glasses Audio Layout for Real-Time Hearing Assistance
Opposite-temple microphone and speaker placement enables real-time hearing assistance while reducing echo, weight, and power use.
- Bone Conduction Hearing Aid Microphone Layout for Vibration Cancellation
Opposite-phase housing vibrations create a cancellation zone for microphone placement, reducing pickup noise and howling in bone conduction hearing aids.
- Hearing Aid ECG Electrodes for Self-Administered Cardiac Monitoring
Integrated electrodes in a hearing aid let users capture and process ECG signals outside clinics, improving access to arrhythmia monitoring.
- Dual-Microphone Voice Control for Noisy Earpiece Communication
An earpiece compares ambient and ear-canal microphone signals to isolate the wearer's voice from background noise for clearer communication.
- Bone Conduction Hearing Aid Attachment for Stable Ear Fit
A vented adhesive layer, bent rod, and ear-canal plug improve bone conduction hearing aid retention without sacrificing comfort.
- Waterproof Hearing Aid Button Structure Using Pad and FPC Sealing
A waterproof pad and FPC let hearing aid buttons actuate touch switches without housing penetration, improving sealing and service life.
