Abstract: A balanced armature receiver is disclosed that includes a housing and an armature assembly within the housing. The armature assembly includes a first armature portion and a second armature portion. The first armature portion and the second armature portion are operated such that the second armature portion is substantially unstable relative to the first armature portion.

Abstract: An assembly of a receiver and a microphone, such as for positioning in an ear canal of a person. The receiver and microphone are provided in an overlapping relationship to take up less space while being able to emit sound in one direction and receive sound from that direction. When the assembly if for use deep inside the ear canal of a person, the microphone may be very small, as it is exposed to very high sound levels.

Abstract: An inflatable ear piece is used in a hearing aid. The inflatable ear piece defines an inflatable part, which defines an inflatable cavity. The inflatable cavity, when inflated, defines an inflated state in which the inflatable part abuts an inner wall of an auditory canal when provided therein, and, when deflated to a deflated state, allows for insertion and/or retraction of the ear piece from the auditory canal. The inflatable ear piece comprises one or more biasing means that are arranged to bias the inflatable part away from a totally collapsed state and into the deflated state. The biasing means is secured to an inner wall of the inflatable cavity.

Abstract: 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.

Abstract: A method for producing a tube for a hearing aid is disclosed. And more specifically, a method is disclosed for anchoring a fiber to a tube of a hearing aid, the fiber running through the tube. The fiber is positioned within the tube as a reinforcement fiber to improve the pull strength of the tube.

Abstract: A microphone assembly having a housing, a transducer, and an electronic circuit. The housing has an opening, and the transducer is disposed within that opening. The electronic circuit covers the opening such that the transducer is surrounded by at least the electronic circuit and the housing. The electronic circuit includes a substrate and an amplifier for amplifying the electrical signal into an amplified electrical signal which is coupled to a connection means. The connection means provides a direct electrical connection between the electronic circuit and a receiver. The amplifier is mounted on the substrate and disposed on a side of the substrate of the electronic circuit facing the transducer. The receiver is disposed on a side opposite the side and outside the housing.

Abstract: 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.

Abstract: A diaphonic valve utilizing the principle of the Synthetic Jet is disclosed herein. A diaphonic valve pump is provided for the inflation of an in-ear balloon. More complex embodiments of the present invention include stacks of multiple synthetic jets generating orifices as well as an oscillating, thin polymer membrane. In one or more embodiments of the present invention, a novel application is provided for the creation of static pressure to inflate or to deflate an inflatable member (balloon). In addition, sound can be utilized to inflate or deflate an inflatable member in a person's ear for the purpose of listening to sound.

Abstract: A receiver module configured to be seated within an ear canal and optimized for simultaneously inflating an inflatable membrane while generating acoustic waves transmitted to a user. The inflatable membrane can be used to secure the receiver module within the bony portion of the ear canal of the user. A multi-layer valve system and method of assembly are disclosed for a valve system to harvest static pressure from acoustic waves generated within the receiver and direct the increased pressure toward the inflatable membrane to inflate the membrane. The multi-layer valve system can be used to prevent a back flow of air and thereby maintain a static pressure differential between ambient air drawn in through an air ingress port and air forced into the inflatable membrane through an air egress port.
