Beschreibung
Zusammenfassung:	A receiver-in-ear assembly (100) comprises: a housing (104) including a cavity (102a) extending through the housing (104); an optical transducer (201) being mounted in the cavity (102a) within a thickness of the housing (104), the optical transducer (201) being mounted on a circuit board layer (208) such that a spacing (207) exists between a side of the optical transducer (201) and a sidewall (216) of the cavity (102a); the circuit board layer (208) extending underneath the housing (104) and touching the housing (104) such that the optical transducer (201) is held within the cavity (102a) without touching the housing (100); and a protective substance (210) forming a shield over the optical transducer (201) and the cavity (102a), the protective substance (210) configured to affect a field of view of the optical transducer (201).
