Ear Supported Sets TRIZ Cases
- In-Ear Device Acoustic Seal Assessment Using Dual Microphone Probe
Dual microphone probe measures sound pressure levels inside and outside the ear canal to evaluate in-ear device acoustic seals.
- Modular Hearing Aid Connector Assembly for Reliable Connections
Segmented modular connectors replace fragile wires in hearing aids, reducing electromagnetic interference while enabling rapid component replacement.
- Earphone Hollow Casing for Bass Compensation
Separate hollow casing expands internal volume to reduce back pressure and improve low-frequency reproduction without adding complex components.
- Bone Conduction Audio Device with Piezoelectric Vibrator
Piezoelectric vibration eliminates vent leakage, maintaining loudness sensation and comfort without acoustic pressure loss.
- Dual-Polymer Shell for Coil Alignment in Hearing Implants
Segmented thermoset and thermoplastic zones allow precise coil alignment without deforming the ear canal fit.
- Auditory Prosthesis Stimulation Rate Periodicity
Auditory prosthesis maintains an integer ratio between stimulation frequency and sensed sound periodicity to eliminate electrical pulse jitter.
- Stereo Digital Hearing Device with External Microphone for Spatial Sound
A stereo digital hearing device connects wirelessly to an external microphone-equipped accessory to receive and amplify audio signals directly into the ear.
