Abstract:

A method of making an acoustic assembly for use in a transducer includes forming a multi-layer assembly. The multi-layer assembly includes a first layer member and a second layer member. Each member includes a center portion, an edge portion and an aperture separating the center portion and the edge portion. The assembly has an assembly stiffness that is greater than the stiffness of either the first or second layer members. A hinge joins the assembled first and second center portions and the first and second edge portions such that the assembled first and second center portions is free to at least partially rotate relative to the assembled first and second edge portions about an axis. A flexible layer member is coupled to the assembly and provides airtight sealing of the passageway.

International Classification:

H04R 25/00

US Classification:

381417, 381418, 381322, 381324

Abstract:

An armature for a receiver comprising a first and a second leg portion each having a thickness and a width and connected to each other, and a connection portion in communication with the first and second leg portions. The connection portion has a width greater than the width of the first and second leg portions individually. The connection portion reduces the stiffness of the armature and minimizes magnetic reluctance of the connection between the first and second leg portions. According to one aspect of the invention, the first and second leg portions are integrally formed with the connection portion and the connection portion includes at least a portion having a thickness less than the thickness of the first and second leg portions individually to reduce the stiffness of the armature. According to another aspect of the invention, the first and second leg portions are separately formed and attached to the connection portion in a way that reduces the stiffness of the armature.

H04R 25/00

US Classification:

381423, 381175, 381431

Abstract:

An acoustic assembly for use in a transducer includes a multi-layer structure. A first layer member includes a first center portion, a first edge portion and a first aperture separating the first center portion and the first edge portion. A second layer member includes a second center portion, a second edge portion and a second aperture separating the second center portion and the second edge portion such that the second center portion is free to move relative to the second edge portion. The first and second layers are formed into an assembly wherein the first center portion and the second center portion are coupled, the first edge portion and the second edge portion are coupled, and the first aperture and the second aperture are substantially aligned to define a passageway. The assembly has an assembly stiffness that is greater than the stiffness of either the first or second layer members. A hinge joins the assembled first and second center portions and the first and second edge portions such that the assembled first and second center portions is free to at least partially rotate relative to the assembled first and second edge portions about an axis.

International Classification:

H04R 25/00

US Classification:

381182000

Abstract:

A receiver includes a housing having an interior, a diaphragm assembly disposed within the housing, a motor assembly disposed within the housing and a linkage assembly coupling the diaphragm assembly and the motor assembly. A support structure joined to the diaphragm or the motor assembly or to both the diaphragm and the motor assembly. The support structure includes a cooperative surface portion engaging the housing to position and retain the joined diaphragm assembly or motor assembly within the interior. A corresponding method of manufacture employs a support structure for positioning components of the receiver in the housing. A receiver may also incorporate a microphone to through pass acoustic signals external to the receiver housing through the receiver. An earphone assembly may incorporate a receiver as described.

Abstract:

An optical apparatus includes a first membrane, a second membrane and at least one electromagnetically displaceable component. The first membrane includes an optically active area. The first membrane and the second membrane are coupled by a filler material disposed in a reservoir. At least one electromagnetically displaceable component is coupled to the filler material via the second membrane, such that a displacement of the at least one electromagnetically displaceable component is operative to cause a deformation of the optically active area of the first membrane by movement of the filler material.

International Classification:

G02B 7/10

Abstract:

An optical apparatus includes a housing, a deformable lens, and a lens shaper. The lens shaper defines the shape of the deformable lens. A first mechanism is positioned within the housing to adjust an optical property of the deformable lens. A second mechanism is positioned within the housing to adjust an optical property of the deformable lens. The second mechanism is at least one of an electromechanical actuator or motor. The first mechanism and the second mechanism are different types of mechanisms.
