Polymeric Diaphragms TRIZ Cases
- Speaker Diaphragm Curved Geometry Prevents Circuit Collisions
Curved lower vibrating diaphragm prevents collisions with the flexible circuit board, improving acoustic quality and stability.
- LED Illumination Device with Integrated Speaker Sound Extraction
A frame member creates a separate extraction part between inner and outer light-reflection plates to guide acoustic vibrations from the internal sound source.
- Waterproof Earplug with Wireless Audio and Acoustic Vent
Waterproof earplug uses acoustic vent membrane to maintain sound transmission while blocking water ingress.
- Metamaterial Loudspeaker Diaphragm Anisotropic Design
A metamaterial loudspeaker diaphragm uses alternating soft and rigid concentric circles to control sound wave propagation.
- Acoustic Diaphragm TLCP Edge Heat Treatment
Thermoplastic liquid crystal polymer diaphragms use localized heat treatment to lower edge elastic modulus.
- Light-Curable Voice Coil Attachment for Hard Speaker Diaphragms
A light-transmissive rigid diaphragm allows UV curing of a voice coil adhesive, resolving the conflict between structural stiffness and adhesive transparency.
