摘要： 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.

摘要： A multimedia system includes at least a first pair of satellite loudspeakers for radiating left and right channel signals, the satellite loudspeakers having a first lower cutoff frequency. The loudspeaker system also includes a separate subwoofer having a first upper cutoff frequency. The first lower cutoff frequency is higher in frequency than the first upper cutoff frequency. The loudspeaker system also includes a center loudspeaker array. The center loudspeaker array radiates center channel signals, and also directionally radiates left and right channel signals in the frequency range between the first lower cutoff frequency and the first upper cutoff frequency. The multi-channel loudspeaker system may also incorporate additional satellite loudspeakers for reproduction of surround channel signals.

摘要： An open-ear headphone with an acoustic module configured to be located at least in part in a concha of an outer ear of a user. The acoustic module comprises a housing that contains an acoustic transducer. There is a first sound-emitting opening in the housing that is configured to emit sound produced by the acoustic transducer. The acoustic module defines a central longitudinal axis and the first sound-emitting opening is offset from the central axis.
