Loudspeakers TRIZ Cases
- Display Panel Vibration Control for Sound Pressure Intensity
A display panel acts as a vibration plate driven by an attached actuator to output audio signals.
- Bass Reflex Port Tapered Cross-Section Wind Noise Reduction
Variable spacing in the tubular bass reflex port slows airflow to suppress turbulence and friction-induced wind noise at the opening.
- Loudspeaker Diaphragm Patterns Disperse Stress
Segmented patterns across the suspension ring and fixed portion disperse stress concentrations, preventing warping deformation in molded loudspeaker diaphragms.
- Planar Voice Coil Actuator on Multi-Layer Board
PCB trace coils eliminate wire fatigue in compact speakers, improving reliability while maintaining acoustic output.
- Metal Wire Damper Planar Structure for Compact Sound Devices
A metal wire damper with a planar elastic part reduces resonant frequency and total harmonic distortion in sound-producing devices.
- Horn Enclosure with Partitioned Acoustic Paths
Parallel partitions create unequal acoustic paths to merge driver outputs into a coherent wavefront, eliminating high-frequency interference.
- Acoustic Transducer Heat Dissipation Mounting
Radial fins and extraction paths manage thermal loads while maintaining low stack height.
- Magnet Assembly Suspension for Drop Impact Absorption
Loop springs absorb drop impact energy to prevent voice coil damage in moving magnet actuators.
- Speaker Magnetic Circuit with Opposing Inner and Outer Magnets
Opposing magnetization directions in nested magnets boost flux density, enabling miniaturized speakers without compromising acoustic output.
- Double-Sided Loudspeaker Integral Magnetic Assembly
Injection molding merges magnetic components with speaker bases, reducing assembly complexity and costs.
- Speaker Module Segmented Magnet Design for Thin Profile
Segmented magnet arrangement preserves magnetic force in thin speaker modules, preventing sound pressure degradation during device slimming.
- Microspeaker Acoustical Resistance Assembly Venting
A microspeaker assembly uses segmented vent holes in a back plate and printed circuit board to shape frequency response.
- Integrally-Designed Bone Conduction Driver with Tripod Cup Holder
An integrally-designed bone conduction driver merges the voice coil and vibrating plate using a tripod cup holder.
- Sound Production Device Line-Like Stabilization Component
A sound production device uses a line-like system stabilization component to secure the voice coil assembly.
- Intravaginal Foetal Acoustic Stimulation Device
Wireless intravaginal probe bypasses abdominal tissue barrier to deliver safe acoustic signals directly to the foetus.
- Balanced Iron Core Vibration System for Signal Efficiency
Symmetric magnet groups drive a balanced iron core to eliminate distortion and reduce energy loss in moving iron systems.
- Coaxial Speaker Shared Magnetic Circuit Height Reduction
A coaxial speaker merges treble and bass vibration systems into a single magnetic circuit to reduce overall height.
- Speaker as Microphone via Current Monitoring
Current monitoring separates external sound signals from speaker drive currents, eliminating separate capacitive microphones and reducing power consumption.
- Sounding Device Metal Shrapnel Voice Coil Restraint
Conductive metal shrapnels replace welding and separate suspensions to restrain voice coil swinging, simplifying assembly.
- Coaxial Dual-Voice-Coil Driver Shared Magnetic Circuit
A coaxial dual-voice-coil driver uses a shared magnetic circuit to drive bass and treble coils within a single compact assembly.
- Sounding Device Flange Assembly for Precision Diaphragm Mounting
A flange formed by bending the holder connection portion secures the auxiliary diaphragm to improve assembly alignment.
