Diaphragm Extensions TRIZ Cases
- Planar Voice Coil Speaker Layout for Compact High-Frequency Output
Using a planar voice coil between segmented magnets, this case shows how speaker size is reduced while improving sound pressure and bandwidth.
- Speaker Dome Positioning Structure for Diaphragm Concentricity
A dome edge positioning portion keeps the diaphragm concentric during forming, reducing glue issues, wobbling, and speaker reliability loss.
- Microphone Acoustic Attenuator With Protective Enclosure for High-SPL Capture
A diaphragm and enclosed volume lower sound pressure before it reaches the microphone, preserving clear speech capture near the mouth.
- Acoustic Transducer with Integrated Passive Diaphragm
Merges active and passive diaphragms into a single assembly, resolving the contradiction between device size and bass performance.
- Loudspeaker Cantilever Mass Vibration Control
Cantilever mass projects from shank to control membrane vibrations, minimizing weight while improving sound pressure levels.
- Variable Shape Speaker Surround With Segmented Ribs
Segmented ribs on a circular surround increase stiffness to prevent buckling at high displacements while maintaining linear force behavior.
- Electro-acoustic Diaphragm Pedestal Lap Joint for Robust Voice-coil Mounting
Adhesively bonded pedestal lap joint transfers voice-coil force to the diaphragm, resolving weak connection limits that restrict output levels and excursions.
- Electroacoustic Transducer Tubular Coupling Durability
A tubular portion couples the diaphragm and voice coil, strengthening durability while maintaining wide directivity across frequencies.
