Receiver

A miniature receiver including a first moveable diaphragm being acoustically connected to an intermediate volume, and a second moveable diaphragm being acoustically connected to the intermediate volume and a rear volume. The acoustic compliance of the intermediate volume is smaller than the acoustic compliances of the respective first and second moveable diaphragms. An associated method is also disclosed.

Miniature receiver

A miniature speaker having at least a first and a second resonance in its frequency response. The miniature speaker includes a diaphragm for generating sound pressure waves in response to electrical drive signals, one or more sound channels at least partly surrounding a total air volume forming an acoustical mass, and one or more intermediate air volumes being acoustically connected to the one or more sound channels. The acoustical mass provides that the second resonance in the frequency response of the miniature speaker is positioned within an audible range.

Miniature speaker with acoustical mass

A receiver-in-canal (RIC) assembly for positioning in or at an ear canal of a user. The RIC assembly includes a housing having an opening between an exterior space outside the housing and an internal space inside the housing, and a cable connection located in the housing and facilitating connection of a cable to the RIC assembly. Furthermore, the RIC assembly includes a first diaphragm extending in a first plane in the housing, and a first motor electrically connected to the cable connection and operatively connected to the first diaphragm. The cable connection is located relative to the first diaphragm such that at least a part of it can be projected onto a movable part of the first diaphragm in a direction perpendicular to the first plane and where the cable connection means is located in continuation of the first motor in a plane parallel to the first plane.

Receiver-in-canal assembly comprising a diaphragm and a cable connection

A transducer assembly with a U-shaped element at least a part of which forms a part of a magnet housing is disclosed. One or more magnets are attached to the magnet housing which is adapted to conduct magnetic flux from one or more magnets.

Motor assembly

A compact moving armature receiver where the diaphragm element is positioned in the air gap of the magnet assembly and where a suspension element is provided for defining the front chamber, the suspension element has a stiffness of at the most 500 N/m. The suspension element and the diaphragm element may be made from the same sheet of a foil, and the suspension element may be formed by bent or curved peripheral parts of the foil.

Moving armature receiver

The present invention relates to a receiver module being adapted to be positioned in an ear canal, the receiver module comprising a receiver having a receiver housing, said receiver being adapted to receive a time dependent electrical signal, said receiver further being adapted to generate outgoing acoustic waves via an output port in the receiver housing in response to the received time dependent electrical signal, and expansible means surrounding at least part of the receiver housing, said expansible means having an opening aligned with the output port of the receiver housing so as to allow the generated outgoing acoustic waves to penetrate away from the receiver module and into the ear canal.
