Electrical Transducers TRIZ Cases
- Loudspeaker Magnetic Flux Collector Design
A magnetic flux collector channels energy from multiple magnets to the air gap, reducing power requirements.
- Rectangular Cross-Section Coil for Electrodynamic Transducer
Folding flat conductors into a polygonal shape resolves magnetic flux inefficiency caused by large corner radii in conventional wound coils.
- Multi-Layer Coil Arrangement for Enhanced Electromagnetic Force
Overlapping conductor sections in a multi-layer coil arrangement increase Lorentz force to improve sound wave generation efficiency.
- Ultrasound Transducer Activity Uniformity via Laser Material Removal
Laser ablation selectively removes piezoelectric material from high-activity zones to correct acoustic nonuniformity and prevent tissue overheating.
- TMR Read Transducer ESD Protection via Segmented Resistors
Segmented parallel and shunt resistors protect TMR sensors from ESD damage without complicating wafer-processing steps.
- Perpendicular Vibration Actuator Cantilever Support
A vibration actuator uses a cantilevered elastic support to reciprocate a coil and magnet assembly.
- Hearing Aid Conductive Layer Integration for Miniaturization
A conductive layer integrated into the housing inner surface enables direct electrical connections for hearing aid devices.
- Magnetic Head Read Sensor Stripe Height Control via Segmented ELG Patterning
Segmented patterning decouples read sensor and electronic lapping guide formation to enable precise air bearing surface lapping.
- Micro-Geophone Lipless Pole Pieces and Adhesive Bonding
Lipless pole pieces and adhesive bonding reduce geophone diameter, resolving the contradiction between miniaturization and signal detectability.
- Damper Voice Coil Thin Speaker Design
A damper voice coil integrates structural support with electromagnetic actuation in thin speakers.
- Ultrasound Transducer Electrode Patterning via Laser Ablation
Laser ablation patterns electrodes on composite dielectric materials, eliminating wire bonding complexity and reducing thermal budget constraints.
- Display Device Panoramic Sound Using Top Side Middle Circuits
A display device integrates middle side and top sound production circuits to generate three dimensional audio.
- Ultrasound Sensor Diaphragm Decoupling via Latching Means
Latching means join a decoupling element to a housing section, enabling separate manufacturing and reducing rejection rates from fabrication faults.
- Speaker Center Pole Turbulent Flow Heat Dissipation
A turbulent flow generator inside a speaker center pole through hole creates turbulence to overcome uncontrolled airflow and improve cooling efficiency.
