Microphones TRIZ Cases
- AR/VR Smart Glasses Spatial Audio Filtering for Focused Replay
Spatial microphone filtering helps AR/VR glasses isolate selected audio from ambient noise.
- Acoustic Device Sound Channels for Wind-Noise Reduction
Channel assemblies extend sound paths to improve pickup and reduce wind noise.
- Wall-Mounted Audio Speaker Layout for Direct Front Sound
A speaker module behind the display, damping element, and bass port support direct sound without sacrificing a thin profile.
- Automated Audio Tuning Reports for Multi-Speaker Room Performance
A controller detects speakers and microphones, tunes them with distinct test tones, and reports room performance.
- MEMS Microphone Segmented Backplate for Low-Noise Differential Sensing
A segmented MEMS backplate enables differential sensing with lower noise and simpler fabrication.
- Four-Microphone Audio Processing for Beamforming and Immersive Audio
Strategic front and rear microphone placement supports preprocessing, beamforming, and immersive audio recording in one device.
- In-Ear Headphone Acoustic Fit Detection for Automatic Ear Tip Selection
A headphone speaker and microphone compare frequency responses to identify the best ear tip, reducing manual fit trials.
- MEMS Membrane Reinforcement for Sensitivity and Robustness
A locally reinforced MEMS membrane distributes stress, protecting the device from overload while retaining low-signal sensitivity.
- Dual-Movable-Element Capacitive Electromechanical Design for Pull-In Stability
Symmetric movable elements and pivot hinges improve sensitivity and resonance frequency while stabilizing capacitive bias voltage.
- In-Ear Headphone Damped Vent for Stable Active Noise Control
This case uses a damped vent to limit Helmholtz resonance and dynamic acoustic leaks, reducing artifacts in active noise control.
