Abstract
In one embodiment, an apparatus comprises i) an audio transducer; ii) an audio driver plate having an ear-facing side and a non-ear-facing side; iii) a rigid housing substantially circumferentially surrounding the audio driver plate without substantially covering the ear-facing side and non-ear-facing side of the audio driver plate; iv) a front plate mounted on the ear-facing side of the audio driver plate and spaced apart from the audio driver plate; and v) a fixing gasket affixed to the non-ear-facing side of the audio driver plate. In addition, the front plate is adapted to be compressed against an ear-facing portion of an audio transducer holding device and the fixing gasket adapted to be compressed against a non-ear-facing portion of the audio transducer holding device, whereby the audio transducer is adapted to be held within the audio transducer holding device by compressive force on both the fixing gasket and the front plate.
