AUDIO DEVICE

Abstract:

An audio system including an audio device secured within a receptacle for improving voice communication is disclosed. The audio device includes a housing containing a down-firing speaker that is positioned directly above an acoustic reflector formed by surfaces associated with the bottom of the housing and a corresponding interior of the receptacle. An apex protrudes upward from the center of the receptacle toward the diaphragm of the speaker. The acoustic reflector is characterized by a curved volume extending from the apex to an outer peripheral border of the receptacle. The structural features of the audio device and receptacle are configured to significantly improve the quality of sound produced by the audio system such that it fulfills standardized wideband audio performance requirements in a compact package.
