Polymeric Diaphragms TRIZ Cases
- Skin-Attachable Vibration Sensor for Noise-Resistant Voice Detection
A skin-attachable vibration sensor detects neck vibrations via a crosslinked polymer diaphragm to resolve external noise interference in voice recognition.
- Temperature Stable Loudspeaker Membrane Plate Structure
Foam core sandwich membrane plate maintains mechanical stiffness across 180°C range while reducing weight.
- Speaker Diaphragm Using Thermoplastic Polyester Elastomer Film
A speaker diaphragm uses a thermoplastic polyester elastomer film layer to enhance vibration sensitivity and structural resilience.
- Coaxial Loudspeaker Diaphragm With Independent Surface Profiles
Independent surface profiles optimize high frequency horn radiation and low frequency performance without mutual geometric constraints.
