An in-ear hearing device including an adjustable cable assembly is disclosed. The cable assembly includes a shape-configurable portion between an end portion connected an in-ear unit and a flexible end portion adjustably connected to a behind-the-ear (BTE) unit. The flexible end portion is retractably insertable into a housing of the BTE unit to adjust a length of the cable assembly between the in-ear unit and BTE unit. A cable-retention member of the BTE unit is engageable with the flexible end portion of the cable assembly to fix the cable assembly relative to the BTE unit.

Sound-producing acoustic receivers are disclosed. The acoustic receiver includes a receiver housing with a first internal volume and a second internal volume, a first diaphragm separating the first internal volume into a first front volume and a first back volume such that the first front volume has a first sound outlet port, a second diaphragm separating the second internal volume into a second front volume and a second back volume such that the second front volume has a second sound outlet port, a motor disposed at least partially inside the housing such that the motor including an armature mechanically coupled to both the first diaphragm and the second diaphragm, an acoustic seal between the first front volume and the second back volume such that the acoustic seal accommodates the mechanical coupling of the armature to one of the first diaphragm or the second diaphragm.

Acoustic receivers with multiple diaphragms

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.

An acoustic receiver includes a first receiver subassembly having bottom housing plate with at least a portion of a motor fastened thereto, and a second receiver subassembly having a closed-ended housing wall with at least one open end that is fastened to the bottom housing plate. A method of making and assembling the components is also described.

Two coils are wrapped in one of numerous different implementations. In one implementation, the two coils are wrapped about a portion of a bobbin that has at least three flanges. The first coil is disposed about a first portion of the bobbin between the first flange and the second flange, and a second coil is disposed about a second portion of the bobbin between the second flange and the third flange.

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.

Balanced armature receiver

Sound-producing acoustic receivers are disclosed. The acoustic receiver includes a housing, a first diaphragm, and a motor. The housing has an internal volume separated by the first diaphragm into a first front volume and a first back volume such that the first front volume has a first sound outlet. The first diaphragm includes a first paddle movable about a first hinge. The motor is disposed in the housing and includes an armature mechanically coupled to the first paddle. The first hinge is located between opposite ends of the first paddle such that actuation of the armature pivots both ends of the first paddle about the hinge.

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.

Methods and apparatus change operation of a hearing device based on a state of an acoustic valve in the hearing device. In some examples an electrical circuit performs one or more of differing operations depending on a state of the acoustic valve. Some operations change the signal to a sound producing transducer and other operations change other operations of the hearing device. For example, an electrical circuit changes active noise cancelling operation, changes equalization settings, provides noise reduction improvements, provides beam forming changes and other operations based on a state of the acoustic valve. In some implementations, a change in acoustic valve state is used to change the operation of the hearing device.
