Plane Diaphragms TRIZ Cases
- Stiffened Diaphragm for In-Ear Driver Resonance Control
A stiffening element on the diaphragm inner region reduces structural resonances and boosts sound pressure output in miniaturized drivers.
- Planar Metal Damper for Compact Sound Devices
Integral winding of a planar metal damper reduces height occupation while improving fatigue resistance.
- Angled Magnet Shapes for Planar Magnetic Drivers
Tapered magnet surfaces direct sound waves forward, eliminating trapped acoustic energy and distortion in planar drivers.
- Planar Loudspeaker Direct Electrical Connection Eliminates Solder
A planar loudspeaker design integrates direct electrical terminals with the diaphragm conductive path to simplify assembly.
- Miniature Speaker Diaphragm Stiffener Border Segmentation
Segmented diaphragm with stiffener and border zones controls vibration frequencies to expand radiation area without increasing magnetic circuit size.
- Piezoelectric Vibrator with Polylactic Acid Laminate
Oriented polylactic acid film layers in a piezoelectric laminate expand and contract together to drive sound wave generation.
- Speaker Groove Structure for Voice Coil Positioning
A speaker groove recesses the upper plate to position a second auxiliary magnet closer to the voice coil.
- Electroacoustic Transducer Support Body Asymmetry
Support body projections and depressions equalize air removal to reduce distortion during low-pitched sound reproduction.
