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.
