Disclosed is hearing device that uses magnetostrictive materials to assist a user in hearing and comprehending sounds. Conductive coils (100) are made with a magnetostrictive covering (102) that can comprise a film or other coating. In addition, printed circuit boards can be used with traces that form a coil to generate a magnetic field that activates a magnetostrictive film disposed over the coil traces on the printed circuit board. Enhanced effects are achieved using these systems. Delays in the signal processing can also be introduced by varying the thickness of the magnetostrictive coverings (102).

L'invention concerne un dispositif auditif qui utilise des matériaux magnétostrictifs pour aider un utilisateur à entendre et comprendre des sons. Des bobines conductrices (100) sont fabriquées avec un recouvrement magnétostrictif (102) qui peut comprendre un film ou un autre revêtement. De plus, des cartes à circuit imprimé peuvent être utilisées ayant des traces qui forment une bobine pour produire un champ magnétique qui active un film magnétostrictif disposé sur les traces de bobine sur la carte à circuit imprimé. On maintient des effets renforcés en utilisant ces systèmes. Des retards dans le traitement de signal peuvent aussi être introduits en modifiant l'épaisseur des recouvrements magnétostrictifs (102).
