Loudspeaker Diaphragm Shape TRIZ Cases
- Dual-Speaker Headset Layout for Compact High-Frequency Output
A circumferential dual-speaker layout separates low and high frequencies to improve headset sound output without blocking sound or enlarging the housing.
- Speaker Edge Dome Adhesive Structure for Larger Vibrating Area
A thin inclined edge-dome adhesive structure cuts lost diaphragm area, raising sound pressure while preserving stability in ultra-small speakers.
- Earpiece Speaker Module with Circumferential Layout for Reduced Interference
A compact earpiece module assigns different frequency ranges to two speakers while circumferential spacing limits acoustic interference.
- Speaker Membrane Periphery Bending for Radiating Area
A speaker membrane periphery bends perpendicular to vibration direction, preserving active radiating area.
- Speaker Diaphragm Suspension Vertical Positioning
Vertical suspension positioning maintains diaphragm area and lowers resonance frequency despite reduced outer diameter.
- Loudspeaker Vibrator Placement for Casing Vibration Control
Strategic vibrator placement balances opposing forces to eliminate casing rattling and remove the need for dampening structures.
- Speaker Damper with Multi-Level Planar Surface for Rupture Prevention
A speaker damper uses a multi-level planar surface to control deformation and protect the oscillatory system from excessive input signals.
- Undulating Speaker Surround Geometry for Non-Pistonic Motion Control
An undulating speaker surround film distributes stresses to limit non-pistonic motion and prevent voicecoil rubbing at resonant frequencies.
- Rectangular Diaphragm Corner Radius Inversion for Stiffness
Inverting the mean inner and outer corner radii on a rectangular diaphragm increases stiffness and reduces wobbling, resolving mechanical stress issues.
- Electro-acoustic Transducer Diaphragm Asymmetric Ribs
Asymmetric rib patterns on the moving surface increase breakup frequency and smooth the frequency response by disrupting circumferential vibration modes.
- Loudspeaker Non-Uniform Suspension Stiffening Element
A loudspeaker uses a stiffening element to counteract membrane flexure caused by non-uniform surround forces.
- Diaphragm Edge Structure for Passive Radiator Vibration Control
An asymmetric edge design with gradual shape changes suppresses rolling in passive radiators, preventing abnormal sound while maintaining bass reproduction.
- Routing Conductors in Electro-Acoustic Transducer Magnetic Circuits
A transducer routes conductors through magnetic circuit slots to maintain electrical connections during cone motion.
- Micro-Speaker Surround with Continuous Corner Corrugations
Continuous corner corrugations in micro-speaker surrounds reduce stress concentrations and fatigue by distributing deformation evenly.
- Diaphragm Pleat Pattern for Low-Frequency Distortion Control
Segmented pleats in the diaphragm suspension prevent creases and concaves during vibration, reducing low-frequency distortion.
- Wave-Shaped Suspension Edge for Loudspeaker Vibration Control
A wave-shaped suspension edge constrains vibration element movement to the axial direction using elastic retaining sections.
- Racetrack Loudspeaker Cone with Non-Uniform Surround Cross-Section
A racetrack loudspeaker diaphragm uses a non-uniform surround cross-section to ensure balanced axial movement.
- Discrete Mass Loading for Piston Loudspeaker Diaphragm Resonance
Separate radial masses induce a dominant bending moment to dampen standing waves on the diaphragm surface.
- Speaker Diaphragm Arcuate Edge Depression
Depressing the diaphragm edge toward the magnetic gap reduces speaker height while maintaining sound quality through optimized vibration amplitude.
- Speaker Edge Rib Limits Diaphragm Stroke
A protruded rib on an elastic edge restricts reverse stroke to prevent voice coil collisions and preserve sound quality.
