Transducer Details TRIZ Cases
- Double-Sided Speaker Interconnected Resonance Spaces
A double-sided speaker design merges two acoustic chambers into a single volume using overlapping magnetic circuit modules and voice coils.
- Haptic System With Imbalanced Masses For Independent Frequency Control
Imbalanced drive units generate independent frequency and amplitude control, resolving the trade-off between response speed and signal versatility.
- Inside-Wound Voice Coil Bobbin for Loudspeaker Thermal Management
A voice coil wound on the inside of a bobbin maintains proximity to a conductive front plate for efficient heat transfer.
- Laser Ultrasonic Inspection Diaphragm for Compact NDT
An intermediary diaphragm converts laser light to ultrasonic waves, enabling volumetric and surface inspections of complex shapes without object deterioration.
- Vehicle Sound Generator Yoke Segmentation for Compact Design
Segmented yokes in vehicle sound generators allow internal vibration while keeping the coil stationary.
- Stacked Sound Chambers for Waterproof Medical Device Audio
Stacked sound chambers and vibrating diaphragms generate audible alerts in sealed medical devices.
- Wireless Speaker Network for Portable Audio Quality and Battery Life
A wireless speaker communication method coordinates multiple portable audio devices to deliver optimized acoustic output.
- MEMS Microphone Ceramic Package for Harsh Environments
A MEMS microphone system uses a ceramic package base and metal lids to form an acoustic chamber with integrated EMI shielding.
- Rollable Display Panel Vibration for Sound Output
A vibration generator adapts to the curved shape of an unwound display panel to output sound directly to viewers, avoiding interference from walls and ground.
- Virtual Assistant Wake-Up Filter for False Activation
Spectral fingerprint analysis distinguishes human speech from electronic device output to prevent false virtual assistant activations.
- Dual Ring Magnet Speaker Driver Magnetic Circuit
Segmented inner and outer magnets establish orthogonal field lines to eliminate voice coil rocking modes in audio drivers.
- Linear Motor Single Coil Winding Air Gap Reduction
A linear motor uses a single continuous coil winding to bridge the air gap between magnets, simplifying the internal structure.
- 3D Audio Rendering Position Correction for View Switching
Position correction information adjusts audio positional data to match different camera views during transmission.
- Magnet-less Voice Coil Actuator Using Pot Core Electromagnet
A magnet-less electromagnetic voice coil actuator uses a pot core structure to generate magnetic fields for audio transduction.
- Voice Coil Former Stiffener Using Corrugated Support
Corrugated support member reinforces voice coil former inner surface, reducing unwanted resonance and shifting vibration out of the audible range.
