An assembly of at least one radiation detector, at least one radiation emitter and a housing configured to be positioned inside the ear canal of a person or animal, the detector(s) and emitter(s) being provided in or on the housing, the emitter(s) being configured to emit radiation away from the housing and the detector(s) being configured to receive radiation directed toward the housing. No overlap may be provided between the field of view of the radiation detector(s) and the emitter(s), such as by providing a blocking element.

Housing comprising a sensor

An assembly of a receiver and a microphone, such as for positioning in an ear canal of a person. The receiver and microphone are provided in an overlapping relationship to take up less space while being able to emit sound in one direction and receive sound from that direction. When the assembly if for use deep inside the ear canal of a person, the microphone may be very small, as it is exposed to very high sound levels.

Assembly of a receiver and a microphone

A multi-layer armature for a moving armature receiver. The armature includes a first armature layer and a displacement region. The first armature layer includes a first surface and a second armature layer having a second surface positioned adjacent to the first surface. The displacement region provides relative displacement between the armature layers.

Multi-layer armature for moving armature receiver

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 receiver or loudspeaker having a plurality of sound generators each having a housing and a sound output. An oblong channel is formed by a channel-forming element and parts of the housings. The sound outputs are positioned on one side of a middle of the channel and a outlet of the channel is positioned on the other side of the middle of the channel so that the channel has a length adapted to acoustically alter the sound. The use of the housings for forming the channels provides a more compact structure.

Apparatus for outputting sound comprising multiple receivers and a common output channel

The present invention relates to dual-diaphragm electroacoustic transducers wherein a common magnetic flux path comprises first and second magnetic gaps and a magnet assembly. The invention may provide a miniature transducer with a compact magnetic flux path of improved performance. Electroacoustic transducers in accordance with the invention may comprise a small number of separate parts and provide good acoustic conversion efficiency in a miniature or compact housing.
