Bone Conduction Transducer Hearing Devices TRIZ Cases
- Earphone LDS Antenna Sidewall Layout for Compact Housing
An LDS antenna on the earphone sidewall cuts antenna volume, frees internal space, and broadens housing material choices.
- Bone Conduction Speaker Magnetic Circuit for Higher Sensitivity
A nested magnetic circuit raises field strength in the gap, boosting bone conduction speaker sensitivity while reducing size and weight.
- Bone Conduction Speaker Magnetic Circuit for Stronger Gap Flux
A nested magnetic circuit concentrates flux in the gap to raise bone conduction speaker sensitivity while reducing magnet volume and weight.
- Bone Conduction Speaker Magnetic Gap Design for Compact High Output
Multiple magnetic elements concentrate flux in the gap, boosting bone conduction speaker output and sensitivity without added size or weight.
- Bone Conduction Speaker Magnetic Circuit for High-Flux Gaps
Nested magnetic elements and guide parts concentrate flux in the gap, boosting bone conduction speaker sensitivity and efficiency with less weight.
- Bone Conduction Microphone Layer Structure for Noise Vibration Damping
Elastic dielectric layers with a rough interface absorb external noise vibrations, improving bone conduction microphone signal-to-noise ratio.
- Mechanical Impedance Model for Bone Conduction Facial Coupling
A mass-spring-damper impedance model reproduces facial-region loading near the auricle for more accurate bone conduction vibration testing.
