Abstract: An ear-worn hearing device including an acoustic transducer and a physiological sensor located between an acoustic sealing flange and an inner end portion of the hearing device is disclosed. The flange can be integrated with the hearing device or be an integral part of a removable ear dome. The flange is configured to form at least a partial seal with the user's ear. The flange can also prevent light from entering into the user's ear canal. A removable ear dome can be located on the hearing device by a portion of the physiological sensor protruding from the housing.

Abstract: A balanced armature receiver including a motor with a yoke for retaining magnets and fastening to an armature are disclosed. The yoke includes a close-ended wall structure formed of a soft magnetic material having multiple folded corners defining an armature passage. A first magnet retaining wall portion of the yoke is arranged in parallel with, and opposite, a second magnet retaining wall portion, wherein at least a portion of the first magnet retaining wall portion has a reduced thickness relative to other wall portions of the close-ended wall structure. The armature is connected to the reduced thickness portion of the first magnet retaining wall portion, thereby reducing an overall z-axis dimension of the motor.

Abstract: Acoustic valves include a housing having an acoustic inlet, an acoustic outlet, and an acoustic passage between the inlet and the outlet. An electrical coil is disposed in the housing and configured to generate a magnetic field when energized by an actuation signal. A spring is coupled to an armature movably disposed in the housing between a first surface and a second surface. The valve has a first stable state wherein the armature is positioned against one surface when the electrical coil is not energized, and the valve has a second stable state wherein the armature is positioned against the other surface when the electrical coil is not energized. The armature is movable between the first and second states when the electrical coil is energized, wherein the acoustic passage is more obstructed when the armature is in one state than when the armature is in the other state.

Abstract: A hearing device includes a housing with a retention flange defining a retention space. A conduit is disposed about an electrical wire electrically coupled to a transducer and a ferrule is disposed about an end portion of the conduit and fixed along an axial dimension of the conduit, the ferrule having a portion disposable in the retention space. A bushing has a portion disposed at least partially about the portion of the ferrule disposable in the retention space, the bushing formed of a soft material relative to a hardness of the ferrule and the housing, wherein the bushing is located between the retention flange and the ferrule and the retention flange captures the conduit relative to the housing when the portion of the bushing is disposed in the retention space.
