Audio assembly for a hearing device

Abstract

The present invention relates to an audio assembly for a hearing device, said audio assembly comprising a nozzle comprising a sound channel and a sound port acoustically connected to the sound channel, wherein the sound channel has a longitudinal axis, a receiver at least partly positioned in the sound channel of the nozzle, wherein the receiver has a longitudinal axis, and wherein a housing of the receiver comprises a sound output port, and a first microphone at least partly arranged in the nozzle, wherein the first microphone comprises a sound inlet port. The longitudinal axes of the sound channel and the receiver are essentially parallel when the receiver is at least partly positioned in the sound channel. Moreover, an acoustic passage defining an acoustic mass exists between a part of a sound channel wall and an outer housing part of the receiver, and the acoustic passage extends in the direction of the longitudinal axis of the sound channel, and the acoustic passage is acoustically connected to the sound port of the nozzle and to the sound output port of the receiver whereby the acoustic passage is arranged between the sound port of the nozzle and the sound output port of the receiver. The receiver may comprise a hinged diaphragm and a voice coil secured thereto, and the hinged diaphragm is adapted to deflect in response to a drive signal applied to the voice coil. The present invention also relates to a hearing device comprising an audio assembly.
