The invention relates to a sound channel and a portable audio device comprising such a sound channel, wherein said sound channel comprises a vent path, a closing element and a guiding surface for guiding a movement of the closing element, wherein said closing element is slidably moveable with respect to said guiding surface by a driving means between a first position in which the closing element substantially closes the vent path and a second position in which the closing element leaves the vent path open, and wherein the closing element comprises a stop surface that engages a stop element of the sound channel in the first position of the closing element and a sliding surface that extends substantially parallel to said guiding surface, wherein a liquid is present between the sliding surface of said closing element and the guiding surface. The invention also relates to a method of operating such a sound channel.

Sound channel, portable audio device comprising such a sound channel and method of operating such a sound channel

Acoustic valve for a hearing device, including a valve body defining a passageway, and a seat member and shutter member inside the valve body. The shutter member defines a shutter surface that forms a contact portion and a non-contact portion. The shutter member is moveable relative to the seat member to transition the valve between an opened state, wherein the shutter member is removed from the seat member and the passageway is open to allow sound to pass, and a closed state wherein the contact portion abuts the seat member and the non-contact portion blocks the passageway to restrict passage of sound. The contact portion forms a protruding structure that extends from the non-contact portion and towards the seat member, and has a small width along at least one transverse direction to minimise a contact area between the contact portion and the seat member when the valve is closed.

Acoustic valve, and hearing device including such an acoustic valve

A personal hearing device with an outer housing and a sound path with a length of 1-24 mm, a diameter of 0.5-6 mm, a roll of frequency of at least 500 Hz and with a valve configured to open and close the sound path. The sound path has suitable acoustical properties to act as a sound passage for open/closed hearing aids or hearables. The valve is selected to have a small influence on the acoustical properties of the remaining portions of the sound path.

Personal hearing device

A method for controlling a controllable acoustic valve of a hearing device. The valve includes a moveable valve element adapted to be positioned in one of at least two essentially stable states. The moveable valve element is configured to be maintained in each of the essentially stable states by a retention force. A neutral point with essentially cancelling retention forces exists between the least two essentially stable states. The method includes providing a first drive signal to the controllable acoustic valve to overcome a retention force of a first essentially stable state in order to initiate movement of the moveable valve element from the first essentially stable state to a second essentially stable state. The provided first drive signal is capable of bringing the moveable valve element from the first essentially stable state and beyond a neutral point between the first and second essentially stable states.

Electronic circuit and in-ear piece for a hearing device

A sound channel with a side opening which may be opened or closed by an electromagnetic actuator. The sound channel may remain open and may thus be used as a spout of a sound generator for e.g. a hearing aid, where the side opening may be used as a vent.

Sound channel element with a valve and a transducer with the sound channel element

A sound channel with a valve positioned in a sound channel, the valve based on an electro-magnetic positioned in a housing positioned in the sound channel without sound travelling through the housing. The valve may be used in hearing devices.

Valve, a transducer comprising a valve, a hearing device and a method

The present invention provides a receiver comprising a housing, an armature, and a magnet assembly, where the armature and the magnet assembly are arranged in the housing. The magnet assembly comprises a magnet and a magnet shell. The magnet shell forms an inner space in which the magnet is provided, and where at least a part of the armature extends in the inner space. The magnet shell comprises at least two shell parts forming an inner surface encircling the inner space, where each of the shell parts comprises a first and a second end face. The first end face of a first shell part abuts one of the first and second end faces of an adjacent shell part, and the second end face of the first shell part abuts one of the first and second ends faces of an adjacent shell part.

Magnet assembly

A receiver assembly including a receiver and an assembly housing. The receiver includes a sound outlet configured to outlet sound from the receiver. Furthermore, the receiver includes at least a first and a second outer surface and is arranged at least partly within the assembly housing. The assembly housing includes an assembly sound outlet arranged in communication with the sound outlet for outlet of sound from the receiver via the assembly outlet. The receiver assembly further includes a suspension structure having at least one suspension element, the suspension structure suspending the receiver in the assembly housing. The suspension element connects the receiver and the assembly housing, and the suspension element is formed by a sheet material and is an elongated element extending in an longitudinal direction and is configured to dampen vibration of the receiver by deflection of the suspension element in a direction transverse to the longitudinal direction.

Receiver assembly

The present invention provides a receiver assembly comprising a receiver and an assembly housing. The receiver comprises a sound outlet configured to outlet sound from the receiver. The receiver is arranged at least partly within the assembly housing. The assembly housing comprises an assembly sound outlet. The sound outlet is arranged in communication with the assembly sound outlet for outlet of sound from the receiver via the assembly sound outlet. A vibration dampening element connects the sound outlet and the assembly sound outlet. The vibration dampening element is formed by an elastic foil and is compliant to reduce vibrations from the receiver to the assembly housing.

A receiver including a housing defining a chamber, and a motor assembly that includes a magnet assembly and an armature. The receiver includes a diaphragm operationally attached to the armature. The motor assembly is attached to the housing by a movable suspension structure. A method of reducing vibrations includes providing a housing defining a chamber, providing a motor assembly including a magnet assembly and an armature, providing a diaphragm, providing a movable suspension structure, attaching the diaphragm to the armature, and attaching the motor assembly to an inner wall of the housing by the movable suspension structure.

Receiver having a suspended motor assembly

A loudspeaker having a first magnet configured to output a first magnetic field in a first magnet gap, an elongate armature extending through the first magnet gap, a first coil configured to generate a magnetic flux in the armature, a first diaphragm, a first element configured to transfer force and/or movement from the armature to the first diaphragm, a base and a first and a second support element, the first support element connecting the armature to the base at a first longitudinal position at a first side of a predetermined portion along the length of the armature, and the second support element connecting the armature to the base at a second longitudinal position at a second, opposite side of the predetermined portion. The base may flex between a U-shape and an inverted U-shape and may thus provide force to move the diaphragm.

Loudspeaker, an armature and a method

The present invention relates to a compact and robust hybrid receiver comprising a moving coil type receiver and one or more moving armature type receivers, wherein the moving coil type receiver and the moving armature type receiver, at least partly, share a common magnetic circuit.

Hybrid receiver module

A transducer having a housing defining a chamber, a bent armature with a first leg and a second leg, a magnet assembly for providing a magnetic field in an air gap, and a coil comprising a coil tunnel. The coil tunnel and the air gap extend substantially parallel or perpendicular to each other. Furthermore, the first leg extends in a first direction through the coil tunnel and the second leg extends in a second direction through the air gap.
