Abstract
An open audio device includes a housing and an acoustic radiator in the housing and that emits front-side acoustic radiation from its front side and emits rear-side acoustic radiation from its rear side. A front acoustic cavity in the housing receives front-side acoustic radiation, wherein the housing defines a front sound-emitting opening. A rear acoustic cavity in the housing that receives rear-side acoustic radiation, wherein the housing defines a rear sound-emitting opening. A support structure is configured to carry the housing on a user's head such that the housing is held proximate an ear of the user with one of the front or rear sound-emitting openings anterior of and proximate the tragus of the ear. The housing comprises an inner end that is configured to be closest to the user's head. The one of the front or rear sound-emitting openings that is anterior of and proximate the tragus of the ear lies at an angle to the inner end of the housing.
