Effect of Driver Mass Loading on Bone Conduction Transfer in an Implantable Bone Conduction Transducer

This paper focuses on transducers, which are the most important components of bone conduction implants. To improve vibration magnitude, we develop a coil transducer in driver mass loading is reduced by about 3.25-fold compared to magnet transducers. We use finite element analysis derive and implement maximum Lorentz force frequency characteristics. compare effect magnitude that an older transducer. The new vibrates 4.4-fold more strongly. between two output measured using artificial mastoid. imparted higher than only below 1.4 kHz, tends be lower at high frequencies. Nevertheless, improved low-frequency region will conductive hearing loss.
