An in-the-ear hearing aid device is disclosed. The device at least one electro-acoustic transducer, and at least one sensor or at least one active electronic component. The at least one electro-acoustic transducer comprises a capsule enclosing a transducer sound active part and a transducer air volume. The transducer air volume is air volume which is enclosed by said capsule and which is in fluid-connection with said transducer sound active part. At least a portion of said at least one sensor or of said at least one active electronic component is provided within said transducer air volume.

The present disclosure relates to a method of performing bilateral dynamic range compression of first and second microphone signals generated by first and second hearing aids, respectively, of a binaural hearing aid system. The method comprises to pick-up sound pressure inside an ear canal of the user's left or right ear by a first microphone to generate a first microphone signal in response to incoming sound and pick-up sound pressure inside an ear canal of the user's opposite ear by a second microphone to generate a second microphone signal in response to the incoming sound.

An earpiece includes an electro-acoustic transducer and a housing that supports the electro-acoustic transducer such that the housing and the electro-acoustic transducer together define a first acoustic volume and a second acoustic volume. The electro-acoustic transducer is arranged such that a first radiating surface of the transducer radiates acoustic energy into the first acoustic volume and a second radiating surface of the transducer radiates acoustic energy into the second acoustic volume. A mesh is disposed along an outlet of the housing and is arranged to inhibit debris from entering the front acoustic volume. A first microphone is supported in the housing. The first microphone includes a microphone port for sensing pressure. A chimney surrounds the microphone port and mechanically couples the first microphone to the mesh.

In one embodiment, the present invention is directed to a contact hearing system comprising: an ear tip including a transmit coil, wherein the transmit coil is connected to an audio processor, including an H Bridge circuit; a first input to the H Bridge circuit comprising an AND circuit wherein a first input to the AND circuit comprises a carrier signal and a second input to the AND circuit comprises an output of a delta sigma modulation circuit, wherein the delta sigma modulation circuit is a component of the audio processor; and a second input to the H Bridge circuit comprising an NAND circuit wherein a first input to the NAND circuit comprises a carrier signal and a second input to the NAND circuit comprises an output of the delta sigma modulation circuit.

A hearing instrument includes: a first portion shaped and sized for placement at a pinna of a user's ear; and a second portion having an earpiece for placement in the user's ear canal; wherein the second portion also comprises a connector assembly configured for electrically coupling to the first portion, the connector assembly having a plurality of connector wires, the plurality of connector wires comprising a first connector wire; wherein the second portion also comprises a receiver or miniature loudspeaker for receipt of an audio drive signal through at least the first connector wire; and wherein the second portion also comprises a non-volatile memory circuit having a data interface configured for receipt and transmittal of module data, the non-volatile memory circuit configured to store the module data, wherein the stored module data at least comprises electroacoustic calibration parameter(s) of the receiver or the miniature loudspeaker.

Embodiments of the invention include a method of preventing ferrite migration in a hearing aid including an antenna stack and a battery stack wherein the antenna stack sits on the battery stack, the method comprising the steps of: conformally coating the top and sides of the antenna stack using a conformal coating material; and separately coating all the surfaces of the battery stack using a separate material.

The present disclosure relates to an in-the-ear part having a closing assembly. The in-the-ear part configured to be attached to a hearing device. The in-the-ear part having a cavity for holding an output transducer and the in-the-ear part having an opening and the closing assembly being configured to fit into the opening. An insert part having an inset part opening for receiving and mounting a connecting member is also mounted to the in-the-ear part, the connecting member configured for mechanically coupling the in the ear part to a behind the ear part of the hearing device. A cover part is further provided, which comprises a recess for receiving and mounting the insert part to the in-the-ear part.

There is provided a hearing aid with a Receiver In The Ear speaker assembly comprising a connecting member with electric conductors connecting a connector at one end, and a receiver housing with a receiver at the opposite end. A microphone housing with a microphone is attached to the connecting member. Placed along the connecting member, the microphone housing with the microphone is separated by a distance from the receiver in the receiver housing, thus reducing acoustic or mechanical feedback problems. Especially, the microphone and connector may share one common housing.

The present disclosure provides a contact hearing device comprising a piezoelectric actuator. The attachment of the piezoelectric actuator to a tympanic membrane can vibrate the tympanic membrane based on a transmission received by the receiver assembly and produce perception of sounds.

An in-the-ear hearing aid device is disclosed. The device at least one electro-acoustic transducer, and at least one sensor or at least one active electronic component. The at least one electro-acoustic transducer comprises a capsule enclosing a transducer sound active part and a transducer air volume. The transducer air volume is air volume which is enclosed by said capsule and which is in fluid-connection with said transducer sound active part. At least a portion of said at least one sensor or of said at least one active electronic component is provided within said transducer air volume.
