Magnetostrictive Transducers TRIZ Cases
- Miniature Moving-Coil Speaker With Flexible Circuit Board
Flexible circuit board routes electrical connections to reduce product installation height and simplify wire-leading in miniature moving-coil speakers.
- Magnetostrictive Microloudspeaker Actuator Design
A magnetostrictive acoustic actuator uses a self-supporting structure and suspensions to generate sound through dimensional changes in an alternating magnetic field.
- Flat Body Actuator for High-Frequency Sound Reproduction
Electric drive excites a flat body to radiate broadband sound waves up to 18 kHz.
- Coaxial Loudspeaker Magnetic Assembly Using Ferrite Magnet
A coaxial loudspeaker magnetic assembly uses a ring-shaped ferrite magnet to create separate air gaps for voice coils.
- Speaker Magnetic Fluid Stability via Flux Density Gradients
Varying magnetic flux density in axial and circumferential directions stabilizes magnetic fluid, preventing agitation and abnormal noise.
- Piezoelectric Speaker Vibration Member with Curved Portion for Directional Sound
A piezoelectric speaker vibration member integrates a round portion to redirect sound waves toward the user without additional reflective sheets.
- Piezoelectric Element Electrode Connection Reliability
A piezoelectric element uses a conductive foil and filling member to establish electrical contact with electrode layers.
- Calibration-Based Beamforming for Noise-Resistant Headsets
Calibrated beamforming combined with non-linear adaptive filtering minimizes ambient noise in small form factor headsets.
