Title (EN) BONE CONDUCTION TRANSDUCER WITH A MAGNET ANVIL
(FR) TRANSDUCTEUR DE CONDUCTION OSSEUSE DOTÉ D'UNE ENCLUME MAGNÉTIQUE
Abstract:
(EN) A bone conduction transducer includes a yoke having a pair of arms, a layer of high permeability steel on a surface of the yoke between the arms, a metal coil, a metallic post that extends into a center portion of the metal coil, a diaphragm, an anvil attached to a surface of the diaphragm, a pair of permanent magnets attached to an opposite surface of the diaphragm, and a pair of springs. A first end of each spring is attached to a respective one of the arms of the yoke, and a second end of each spring is coupled to the diaphragm. The diaphragm is configured to vibrate in response to a signal supplied to the metal coil. The diaphragm could be formed from a from a permanent magnet.
(FR) L'invention concerne un transducteur de conduction osseuse comprenant un étrier ayant une paire de bras, une couche d'acier à haute perméabilité sur une surface de l'étrier entre les bras, une bobine métallique, une tige métallique qui s'étend dans une partie centrale de la bobine métallique, une membrane, une enclume fixée à une surface de la membrane, une paire d'aimants permanents fixés à une surface opposée de la membrane, et une paire de ressorts. Une première extrémité de chaque ressort est fixée à un des bras respectifs de l'étrier, et une seconde extrémité de chaque ressort est couplée à la membrane. La membrane est conçue pour vibrer en réponse à un signal fourni à la bobine métallique. La membrane pourrait être formée à partir d'un aimant permanent.
