The present invention provides a receiver assembly. The receiver assembly comprises a receiver housing comprising a first housing part and a second housing part. The receiver housing defines an inner space, and the first housing part and the second housing part are movable relative to each other to define an open configuration and a closed configuration. The receiver assembly further comprises an armature extending in a first direction in the inner space, and a diaphragm operationally attached to the armature via a drive pin extending in a second direction, where the first and second directions are different. The drive pin and the armature are formed in one part. A circumferential edge part of the diaphragm is arranged in a joint between the first housing part and the second housing part in the closed configuration.

Receiver assembly comprising an armature and a diaphragm

The present invention relates to a receiver assembly comprising a membrane structure comprising a frame portion and a moveable diaphragm, an assembly housing, and an acoustical venting opening connecting an interior volume of the receiver assembly to an exterior volume outside assembly housing, the acoustical venting opening forming an acoustical passage at least through the membrane structure.

Receiver with venting opening

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

An assembly of a transformer and an electrostatic sound generator is especially efficient if the resonance frequency of the diaphragm is in the frequency range in which the generator is operated, such as in the interval of 1-20 kHz. Then, a smaller transformer with a winding ratio of 5000 or less may be used for feeding the sound generator, making the assembly suitable for hearing aid purposes or in-ear products such as for pro audio use.
