20120140966 | MOTOR ASSEMBLY - A transducer assembly with a U-shaped element at least a part of which forms a part of a magnet housing is disclosed. One or more magnets are attached to the magnet housing which is adapted to conduct magnetic flux from one or more magnets. | 06-07-2012 |
20120155694 | MULTI-LAYER ARMATURE FOR MOVING ARMATURE RECEIVER - A multi-layer armature for a moving armature receiver. The armature includes a first armature layer and a displacement region. The first armature layer includes a first surface and a second armature layer having a second surface positioned adjacent to the first surface. The displacement region provides relative displacement between the armature layers. The multi-layer construction of the armature in combination with the displacement region creates considerable design freedom in choosing armature geometry outside conventional bounds posed by the above-mentioned constraint between armature cross-sectional area and its mechanical stiffness. The design freedom can be applied to achieve numerous performance benefits for the moving armature receiver such as higher electroacoustic conversion efficiency, increased maximum sound pressure output or smaller overall length of the multi-layer armature. The smaller length leads to a smaller size of moving armature receivers which is an important performance metric for moving armature receivers for numerous severely size-constrained applications. | 06-21-2012 |
20120255805 | MOVING ARMATURE RECEIVER ASSEMBLIES WITH VIBRATION SUPPRESSION - Moving armature receiver assemblies wherein a first U-shaped armature and a second U-shaped armature are configured for suppression of vibration of a housing structure along a longitudinal housing plane. | 10-11-2012 |
20140112509 | Transducer, A Hearing Aid Comprising The Transducer And A Method Of Operating The Transducer - The invention relates to a transducer comprising a housing, a first and a second diaphragm, and a first and a second signal provider. The housing comprises an inner surface. The first and second diaphragms are positioned in the housing. The first and second diaphragms define a common compartment being delimited by at least both a part of the inner surface and the first and second diaphragms. The first signal provider is configured to convert movement of the first diaphragm into a first signal. The second signal provider is configured to convert movement of the second diaphragm into a second signal. The transducer can be used in a hearing aid. | 04-24-2014 |
20140119584 | HEARING AID WITH A PUMP ARRANGEMENT - A hearing aid comprising a behind-the-ear unit comprising a pump arrangement which is fluidly connected to an inflatable part of an in-the-ear unit. The pump arrangement comprises one inlet valve and two outlet valves which are arranged in series. The valve leakage of the two outlet valves is not identical. | 05-01-2014 |
20140119586 | HEARING AID ASSEMBLY - A hearing aid assembly comprising: a behind-the-ear part adaptor which is adapted to be connected to a behind-the-ear part; an ear piece which is adapted to be secured in the auditory canal of a user, such that sound may propagate into the auditory canal; and an interconnecting tube which is arranged between the behind-the-ear part adaptor and the ear piece, the interconnecting tube defining a first lumen and a second lumen each of which interconnects the behind-the-ear part adaptor and the ear piece, and wherein the interconnecting tube comprises a first connector and the behind-the-ear part adaptor comprises a second connector, the first and the second connectors being adapted to be connected to each other such that interconnecting tube is connected to the behind-the-ear part adaptor. | 05-01-2014 |
20140205123 | BALLOON CONNECTOR FOR A HEARING AID ASSEMBLY - A hearing aid assembly comprising an inflatable ear dome, and in particular, a connector for connecting an inflatable ear-dome to a hearing aid. | 07-24-2014 |
20140305735 | MOVING ARMATURE RECEIVER ASSEMBLIES WITH VIBRATION SUPPRESSION - The present invention relates to moving armature receiver assemblies wherein a first U-shaped armature and a second U-shaped armature are configured for suppression of vibration of a housing structure along a longitudinal housing plane. The first and second U-shaped armatures may be shifted away from each other along a longitudinal housing plane to render the first and second U-shaped armatures partially overlapping in the orthogonal plane with a predetermined overlap distance. | 10-16-2014 |
