Title
(EN) ACOUSTIC VALVE FOR HEARING DEVICE
(FR) SOUPAPE ACOUSTIQUE POUR DISPOSITIF AUDITIF
Abstract
(EN)
Acoustic valves including a housing having an acoustic passage are disclosed. A bobbin located in the housing includes a valve seat and a body member housing a magnetic core. An electrical coil is disposed about a portion of the body member, an axial dimension of the electrical coil substantially aligned with an axial dimension of the magnetic core. The electrical coil generates a magnetic field when energized. An armature is movably disposed in the housing between the valve seat and a second surface of the acoustic valve. The valve has a first stable state when the armature is positioned against the valve seat, and the valve has a second stable state when the armature is positioned against the second surface. The valve seat and the second surface are on opposite sides of the armature. The armature is movable between the valve seat and the second surface when the electrical coil is energized, such that the acoustic passage is more obstructed when the armature is positioned against the valve seat than when the armature is positioned against the second surface.

L'invention concerne des soupapes acoustiques comprenant un boîtier doté d'un passage acoustique. Une bobine située dans le boîtier comprend un siège de soupape et un élément de corps logeant un noyau magnétique. Une bobine électrique est disposée autour d'une partie de l'élément de corps, une dimension axiale de la bobine électrique étant sensiblement alignée avec une dimension axiale du noyau magnétique. La bobine électrique génère un champ magnétique lorsqu'elle est excitée. Une armature est disposée de façon mobile dans le boîtier entre le siège de soupape et une seconde surface de la soupape acoustique. La soupape a un premier état stable lorsque l'armature est positionnée contre le siège de soupape, et la soupape a un second état stable lorsque l'armature est positionnée contre la seconde surface. Le siège de soupape et la seconde surface se trouvent sur des côtés opposés de l'armature. L'armature est mobile entre le siège de soupape et la seconde surface lorsque la bobine électrique est excitée, de telle sorte que le passage acoustique est plus obstrué lorsque l'armature est positionnée contre le siège de soupape que lorsque celle-ci est positionnée contre la seconde surface.
