Solid State Device Transducers TRIZ Cases
- MEMS Piezoelectric Microphone S-Shaped Membrane to Reduce Sound Leakage
An approximate S-shape keeps piezo-membrane petals aligned, reducing sound leakage and limiting dust entry into MEMS microphones.
- MEMS Microphone Vacuum Chamber Floating Gate Transistor
Vacuum chamber eliminates air viscosity to boost mechanical sensitivity while shrinking back cavity volume.
- Directional Acoustic Sensor Noise Attenuation via Resonance Summation
A directional acoustic sensor uses a signal processor to calculate sums and differences of resonance unit outputs for precise noise attenuation.
- Foldable Display Sound Generation via Panel Vibration
Integrated sound generators vibrate display panels to provide audio in folded states while reducing mechanical stress.
- FET Based Sensory Systems for Miniaturized MEMS Microphones
A moving gate field effect transistor converts mechanical motion directly into electrical current through sub-threshold operation.
- ITE ANR Earphone Microphone Placement for Stability and Comfort
Placing a MEMS microphone inside the ear nozzle stabilizes the feedback loop, preventing high-pitched squeals without requiring large uncomfortable nozzles.
- Dual Diaphragm Microphone Acceleration Rejection
Segmented opposing diaphragms sum electrical signals to eliminate acceleration-induced noise from sound wave detection.
