Abstract :
A new of vibration transducer, a DFMT (differential floating mass type) is introduced for use in an MEI (middle ear implant) system. The DFMT transducer is not influenced by external noise magnetic flux and has a very high vibration efficiency because its two magnets, which are glued back to back with the same poles facing, are located in the coil
