Transducer Details TRIZ Cases
- MEMS Substrate Recess for Dielectric Fusion Bonding
Recessed substrates ensure complete dielectric filling to prevent peeling and outgassing during MEMS fusion bonding.
- Loudspeaker Magnetic Circuit Plate Step Design
A plate step displaces the voice coil from yoke leakage flux to maintain symmetric amplitude and reduce distortion at high output levels.
- Battery Shock Absorber for Portable Medical Device
Resilient shock absorbing elements dissipate kinetic energy to protect internal components from impact damage in rigid portable medical device housings.
- Frameless Speaker with Elastic Plate for Diaphragm
Removing the structural frame allows a larger magnetic circuit unit, increasing vibration space and sensitivity in compact micro-speakers.
- Paired Halbach Arrays for Thin Electromagnetic Transducers
Paired Halbach arrays drive a planar voicecoil to reduce z-height, eliminating bulky magnetic return structures in compact audio devices.
- Ultrasonic Horn Cross-Section for Directional Oscillation Control
- Wearable Oral Device Bone Conduction Audio
Bone conduction in a wearable oral device delivers private audio without air radiation, resolving privacy conflicts during social interactions.
- Accessory Recognition via Magnetic Force Detection
Magnetic force sensors detect accessory attachment through intensity and polarity analysis, eliminating wireless communication costs.
- MEMS Microphone Blowout Resistance via Elastic Ventilation
An elastic member dynamically opens a ventilation hole to balance front and rear chamber pressures, protecting the diaphragm from blowing damage.
- Loudspeaker Voice Coil Supporting Section Assembly
A protruding supporting section on the voice coil body enables stress-free gluing of the suspension holder and diaphragm.
- Inverted Dual Coil Transducer Thermal Management
An inverted dual coil transducer design positions the magnet assembly forward of a concave diaphragm to create a low-profile acoustic component.
- Loudspeaker Back Enclosure Active Noise Control
A secondary loudspeaker within a back enclosure generates anti-noise waveforms to cancel backside radiation from the primary driver.
- Wireless Speaker Network Auto-Configuration via Signal Strength
A networked speaker system detects device locations using signal strength to automatically assign audio channels and optimize sound distribution.
- Low Profile Loudspeaker Transducer with Stacked Magnets
Segmented magnets and optimized suspension reduce spurious vibrations while maintaining thin profiles for portable devices.
- Loudspeaker Damper Positioning for Driving Efficiency
Positioning a loudspeaker damper near the magnetic circuit reduces acoustic strain and improves driving efficiency.
- Elastomer Cord Drum Microphone Mount Vibration Isolation
Elastomer cords suspend a rigid bracket to isolate drum microphones from stage vibrations, reducing floor noise and simplifying setup.
