Loudspeaker Diaphragm Materials TRIZ Cases
- Compliant Microspeaker Suspension for Broader Acoustic Output
A low-stiffness suspension lets a miniature loudspeaker use a larger cone area for higher displacement, broader frequency range, and stronger output.
- Integrated Loudspeaker Diaphragm Structure for Full-Range Efficiency
A single-piece diaphragm and near-center edge bonding increase vibration area and suppress resonance for compact full-range, efficient loudspeakers.
- Speaker Edge Groove Geometry for Low-Distortion Diaphragm Motion
A curved groove ridge in the speaker edge improves reaction-force symmetry and linearity, reducing distortion at high diaphragm amplitudes.
- Miniature Transducer With Non-Planar Suspension for Broad Spectrum
Segmented, elastomer-based suspension supports broad spectrum output and higher displacement in drivers measuring 6 mm or less.
- Speaker Spider Varying Corrugation Geometry Stress Homogenization
Azimuthally varying corrugation geometry homogenizes stress on a cloth speaker spider, preventing cracking from uneven force distribution.
- Square Speaker With Rounded Corners To Increase Volume Displacement
Rounded corners with arcuate portions reduce non-uniform deformation at the edges, allowing larger diaphragm excursions and higher sound quality.
- Acoustic Transducer Diaphragm Damping via Segmented Lossy Material
Segmented lossy damping material covers elongated diaphragm openings to disrupt circumferential vibration modes.
- Silica Gel Diaphragm Injection Molding Method
Integrated injection molding unites the dome, frame, and membrane in one step to eliminate uneven adhesion.
- Non-axisymmetric Loudspeaker Suspension Geometry
Non-axisymmetric peripheries on a woven fabric suspension element distribute stress evenly, resolving unbalanced deformation in electroacoustic transducers.
- High Aspect Ratio Microspeaker Dual Plane Suspension
A dual suspension system stabilizes high aspect ratio microspeakers, suppressing diaphragm rocking modes to improve sound pressure output.
- Speaker Assembly Inward Flange Surround Mounting
Inward flange surround mounts directly to speaker frame without clamp, increasing diaphragm area and sound pressure.
- Vibrating Panel Device With Integrated Suspension
Integrated upper suspension replaces separate damper and glue, reducing loudspeaker thickness while preventing voice coil collisions.
- Speaker Voice Coil Lead Wire Fixation on Membrane
A speaker voice coil line lead portion connects to a solder pad formed directly on the conductive silicone membrane.
- Speaker Diaphragm Suspension with Overlapping Holes
Segmented suspension with overlapping holes reduces rigidity and antiphase cancellation for low pitch sound.
- Speaker Diaphragm Convex Suspension Glue Corner Design
A speaker diaphragm uses a convex suspending portion and corner glue layers to enhance structural stiffness.
