A bone conduction hearing aid system includes a hearing aid housing with a hearing aid vibrator. A skin interface has an interface connector offset on an outer interface surface and detachably connected to a housing connector. A skin adhesive connects to the skin of a patient user to transmit the sound vibrations through the skin to underlying skull bone for transmission by bone conduction to a hearing organ of the user. When the skin adhesive is pressed against the skin of the user, the skin is initially engaged during an initial engagement period with an initial adhesive force that promotes removal and relocation of the skin interface, and the skin is fully engaged after the initial engagement period with a full adhesive force greater than the initial adhesive force that promotes a fixed secure connection that resists removal of the skin interface.

Bone conduction hearing aid system

An implantable hearing aid system is disclosed. The system has an external transmitter device and an implantable receiver device, and includes a skin interface to connect the external transmitter device to the head of a user. There is a transmitter connector on the external transmitter device and an interface connector on the skin interface to form a coupling between the skin interface and the external transmitter device to enable connection and disconnection of the external transmitter device to and from the skin interface. The skin interface has an adhesive surface facing the skin so that it can be adhered to the skin on the head of the user. The implantable receiver device has an implant stimulator to stimulate a hearing organ. Sound information is transmitted from the external transmitter device to the implantable receiver device that stimulates the hearing organ of the user.

Implantable hearing aid system

A hearing aid attachment system includes a positioning tool and an interconnection unit. An upper surface of the interconnection unit has a second shape that matches a corresponding first shape of a cavity in the lower surface of the positioning tool so that the upper surface fits into the cavity with a second front surface of the positioning tool against and radially outside the front side of the interconnection unit, with the connection portion of the positioning tool connected to the connecting portion of the interconnection unit. The positioning tool is further configured to be removable from the interconnection unit without removing the interconnection unit from the skin.

Hearing aid system with positioning tool

A hearing aid system with a positioning tool is disclosed. The hearing aid system has a hearing aid, an adhesive interconnection unit and a positioning tool. The interconnection unit can be connected to both the hearing aid and the positioning tool. The positioning tool facilitates a correct positioning of the interconnection unit on the hairless skin area behind the outer ear and ensures that neither the hearing aid nor the interconnection unit touches the skin of the outer ear. The hearing aid position can be fine-tuned by turning it in relation to the interconnection unit.

Hearing aid system with a positioning tool

A bone conduction hearing aid system for generating bone conduction vibrations is disclosed. The bone conduction hearing aid system has a hearing aid with a vibrator. The hearing aid system includes an interconnection unit to connect the hearing aid to the user. There is a coupling between the interconnection unit and the hearing aid to connect and disconnect the hearing aid to and from the interconnection unit. The interconnection unit has connection portion and contact plate portion. The connection portion and the contact plate portion are designed in one integral piece of continuous polymer material. The interconnection unit has a concave or planar adhesive surface that can be adhered to the skin on the head of the user without applying any specific pressure against the skin. The sound vibrations are transmitted from the vibrator to the hearing organ as bone conduction sound vibrations.

The invention relates to a bone anchored hearing aid with a sound processor which generates a vibration signal and serves the signal at a vibrator for transmission of the vibration signal into the skull bone of a wearer and where a resonance damping system is provided in the hearing aid and comprising an electronic notch filter having a notch filter center frequency F1, wherein the notch filter frequency F1 is below a resonance frequency Fof the hearing aid as measured in a standard skull simulator.

Bone conducting hearing aid with connection

The hearing aid system has a sound-to-vibration conversion circuitry including a microphone system, an electronic amplifier and a vibrator. A housing accommodates the vibrator. The vibrator is connected to an abutment that goes through the skin. The abutment is connected to a fixture that is anchored in the skull bone. The sound-to-vibration conversion circuitry has an A/D converter that converts an analogue microphone signal into a digital signal.

Power direct bone conduction hearing aid system

A direct bone conduction hearing aid system for generating direct bone conduction vibration includes a vibrator that is placed in an implanted vibrator unit and an implanted energy-receiving unit that has an energy-receiving inductive coil. A vibrator supply cable connects the implanted energy-receiving unit to the implanted vibrator unit. A mounting arm connects the implanted vibrator unit with an anchoring fixture that is anchored to the skull bone through the skull bone surface. The implanted vibrator unit is positioned in the mastoid cavity. The mounting arm is positioned laterally to the implanted vibrator unit and the bone fixation portion of the anchoring fixture.

The vibrator system is for generating bone conduction vibrations. A magnet () provides a static magnetic flux (&#x3a6;) that follows a first path. A bobbin () is disposed at a center a vibrator (). A housing () encloses the bobbin and has a coil surrounding a center of the bobbin. The coil is powered by an alternating current for providing an alternating dynamic magnetic flux (&#x3a6;) following the first path through a magnetic circuit. The housing has an upper end (). The upper end and the bobbin have a first gap () formed therebetween. The housing has a lower end () opposite the upper end. The lower end and the bobbin have a second gap () formed therebetween. The magnet is positioned so that the static magnetic flux (&#x3a6;) is passing through the first and second gaps in a direction substantially parallel with an axial direction (A) of the vibrator. Suspension means () are provided for suspending the bobbin in a center of the housing.
