Abstract
A dual coil floating mass transducer for assisting a person's hearing is provided. Inertial vibration of the housing of the floating mass transducer produces vibrations in the inner ear. A magnet is disposed within the housing biased by silicone springs so that friction is reduced between the magnet and the interior surface of the housing. Two coils reside within grooves in the exterior of the housing which cause the magnet to vibrate when an electrical signal is applied to the coils.
Claims16
A method of manufacturing a hearing device, comprising:
- providing a cylindrical housing;
- placing a magnet within the housing;
- biasing the magnet within the housing;
- and
- wrapping at least one coil around an exterior of the housing.
A method for manufacturing a hearing device, comprising:
- providing a housing having two ends;
- coupling a pair of coils with an exterior of the housing;
- and
- positioning a cylindrical magnet within the housing so that an electrical signal through the pair of coils causes the magnet to vibrate relative to the housing, the vibration of the magnet causing inertial vibration of the housing.
