A dome for a personal audio device. The dome forms a first flexible circumferential member and comprising a guiding structure extending in a longitudinal direction and forming an interface for guiding sound from or to the personal audio device. The guiding structure comprises a least one sound opening configured for passage of sound from or to the personal audio device in a direction transverse to the longitudinal direction of the guiding structure. The first flexible member is configured to at least partly close the sound opening during insertion of the dome into an ear canal of a user.

Examples of canal hearing devices including a lateral section having a frequency shaping sound port system are disclosed. A lateral section includes an elongate sound channel for receiving an incoming sound and producing a frequency-shaped sound output. The hearing device includes a microphone, a speaker for transmitting sound to the eardrum, and a sound port to receive the frequency-shaped sound output from the elongate sound channel and provide a pathway for the frequency-shaped sound output to reach the microphone.

The present invention proposes a sound tube (3) for an earpiece (1), wherein a first section (4) of an inner surface of the sound tube (3) has a structured surface, in particular a textural pattern forming a relief comprising convexities (13) and/or concavities (11). Alternatively or additionally, the sound tube (3) features a radially extending, circumferential flange (8), annular lip (8′) or collar at an outer surface of the sound tube (3). The present invention is further directed to a sound tube arrangement comprising two of the proposed sound tubes integrally formed in one piece and to an earpiece (1) with such a sound tube (3) or such a sound tube arrangement as well as to a hearing device with such an earpiece (1).

Certain types of hearing aids are designed to be worn completely in the ear. Examples of such hearing aids include in-the-ear (ITE), in-the-canal (ITC), completely-in-the-canal (CIC) type, or invisible-in-the-canal (IIC) hearing aids. Described herein are structures to help prevent wax accumulation in the sound port that conveys sound to the microphone. In one embodiment, an injection molded T-fitting connects to a microphone and provides both a microphone inlet pathway and a wax relief pathway.

A guard for a space access device is configured to output air flow through a distal end portion thereof. The guard includes q housing having a proximal end opening, a distal end opening, and a filter portion positioned between the proximal and distal end openings. The filter includes a first plate having a first opening therethrough and a second plate having a second opening therethrough. When the first plate is overlaid in contact with the second plate, this forms an aperture that extends through both the first and second plates.

An earpiece with structure for positioning and retaining the earpiece and with structure for sealing against the entrance to the ear canal to provide passive noise attenuation. The positioning and retaining structure engages features of the lateral surface of the ear. The structure for sealing against the entrance to the ear canal includes a conical structure.

A hearing device including a housing, a receiver within the housing, and a contaminant guard having a guard sound port and one or both of an outer contaminant receptacle, which is located outward of the guard sound port and that extends around the guard sound port, and an inner contaminant receptacle, which that is located on the central axis of the guard sound port and operably connected to a location outward of the guard sound port.

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.

A hearing device is provided. The hearing device is suitable for being at least partially inserted into an ear canal is provided. The hearing device comprises a barrier. The barrier is configured to prevent foreign matter inside the ear canal from passing. The barrier comprises a body and a structure. The body has a surface. The structure is a microstructure or a nanostructure. The structure is formed on at least a first part of the surface. The first part is thus configured to hinder the foreign matter from adhering thereto. The structure and the body are monolithic.

A hearing device and related methods are disclosed. The hearing device comprises a housing comprising a wall, a microphone inlet comprising a through-going opening, a microphone arranged within the housing for receiving audio via the microphone inlet, a first filter device comprising a first filter material, the first filter device being arranged at the microphone, and a second filter device substantially having the shape of a torus or a hollow cylinder and comprising a second filter material, the second filter device being arranged at the wall, wherein the first filter device is arranged between the microphone and the second filter device, and wherein the through-going opening comprises an outer recess in an outer surface of the wall, wherein the second filter device is arranged in the outer recess.
