Loudspeaker Screens TRIZ Cases
- Speaker Shield Plate Layout for Compact Electronics
A magnetic shielding plate between the speaker and display cuts leakage and protects nearby components in compact electronic assemblies.
- Dual-Vibrating Speaker Diaphragm for Wider Frequency Response
A piezoelectric and electromagnetic vibrating assembly share one diaphragm to widen speaker frequency response without added size or complexity.
- Outdoor Loudspeaker Grille Geometry for AVAS Sound and Water Protection
A porous contoured grille balances water and impact protection with stronger AVAS sound output in critical frequency ranges.
- Speaker Module Plate Geometry for Moisture Outlet Drainage
A reduced-thickness plate section widens the acoustic outlet gap, helping speaker modules discharge moisture and preserve acoustic output.
- Acoustic Cavity Structure Using an Equivalent Sound Chamber Seal
An open-chamber speaker uses a sealed equivalent sound chamber to cut device thickness while preserving waterproofing and audio performance.
- Piezoelectric Loudspeaker Layout for Low-Frequency Sensitivity
Multiple bilateral sound-producing structures expand diaphragm interaction area, lowering resonance and improving low-frequency sensitivity.
- Speaker Surface Diffuser Balancing Audible and Inaudible Sound
A speaker-surface diffusion member with tuned airflow resistance spreads inaudible sound without blocking audible sound propagation.
- Speaker Module Plate Structure for Moisture Discharge
A locally thinned second plate widens the diaphragm gap to drain moisture through the acoustic outlet while preserving speaker output.
- Shared Optical-Audio Port Layout for Minimal Display Bezel
A shared port lets sensors and audio parts pass light and sound through one opening, cutting inactive display area while blocking contaminants.
- Vibration Panel Hole Layout for Forward Sound in Thin Displays
A rear support hole larger than the vibration actuator helps a vibrating display panel project clearer forward sound without separate speaker space.
- Headset Ear Cup Baffle Layout for Clearer Sound Isolation
A segmented ear cup baffle focuses and disperses speaker output while blocking internal and external noise for clearer headset sound.
- Directional Ultrasonic Bark Deterrence With Selective Transducer Aiming
A microphone array locates barking and activates aligned ultrasonic transducers to maintain sound pressure across a wide deterrence area.
- Stacked Acoustic Filter Structure for Speaker Module Impedance Control
Overlapping through-pattern plates block sound-absorbing material entry while tuning acoustic impedance, cutting speaker filter cost and time.
- Acoustic Vent Assembly With Nonporous Membrane Pressure Equalization
A nonporous acoustic membrane and reinforced breathable element balance pressure equalization, sound transmission, and contaminant resistance.
