Transducers For Subaqueous Use TRIZ Cases
- Acoustic Waterproof Assembly for Sound Port Sealing
A waterproof membrane, pressure-bearing support, and gap sealing block liquid at the sound port while preserving microphone acoustic performance.
- Speaker-Based Moisture Detection and Discharge in Electronic Devices
Multiple speakers detect moisture entry, guide device tilting, and drive discharge to protect speaker openings from corrosion and malfunction.
- Speaker-Based Moisture Detection and Discharge in Electronic Devices
Multiple speakers detect moisture by impedance change, guide device tilting, and drive evaporation to restore audio performance.
- Spherical Underwater Sound Recorder for Long-Term Deep-Sea Monitoring
This case uses modular pressure-resistant containers and internal power to extend underwater sound recording without large moorings.
- Elastic Waterproof Speaker Ear Hook for Adaptive Ear Fit
This case combines a flexible sleeve and deformable ear hook to seal a speaker while preserving fit and sound quality.
- Waterproof Microphone Membrane Deformation Control
Stainless mesh and outer inhibiting members prevent inward and outward membrane rupture under extreme water pressure, maintaining waterproof reliability.
- Submersible Loudspeaker With Flexible Diaphragm
An external flexible diaphragm absorbs hydrostatic pressure in water, protecting the internal loudspeaker from damage without blocking sound transmission.
- Reverse Acoustic Calibration for Hydrophone Sensitivity
A reverse calibration method uses a calibrated hydrophone to measure reference sensor sensitivity within an acoustic tank.
- Tapered Speaker Surround for Pressure Equalization
A tapered speaker surround limits diaphragm displacement while maintaining frequency response in compact devices.
- Waterproof Sound-Transmitting Membrane with Liquid-Repellent Layer
A waterproof sound-transmitting membrane uses a liquid-repellent layer on a non-porous resin film to block water entry while allowing acoustic passage.
