An ear receiver positions a transducer in close proximity to the human ear. A housing carries a transducer and has an exterior opening through which audible sound from the transducer radiates. A support arm member has a first end connected to the housing and a second end extending from the housing in a direction substantially parallel to the housing exterior opening. An ear piece is formed to fit around the pinna of a human ear. The ear piece has one end movably connected to the second end of the support arm for rotation about at least two axes. Preferably the ear piece rotates about a first axis which is perpendicular to the support arm and a second axis which is perpendicular to the first axis. A signal delivery mechanism, such as an electrical conductor, is provided for delivering an input signal to the transducer.

DETAILED DESCRIPTION In accordance with one aspect of the present invention an apparatus is provided for positioning a transducer in close proximity to the human ear.
The transducer is of the type which produces audible sound in response to an input signal.
The apparatus comprises a housing for carrying the transducer; a support arm connected to the housing; an ear piece formed to fit around the pinna of a human ear; and a signal delivery means for delivering the input signal to the transducer.
The ear piece has one end movably connected to the support to permit rotation of the earpiece about at least two axes.
In one embodiment an L-shaped member connects the support arm to the ear piece.
The L-shaped member has a first end frictionally and rotatably connected to the support arm for rotation about a first axis which is perpendicular to the support arm and a second end frictionally and rotatably connected to one end of the ear piece to permit rotation of the ear piece about a second axis which is perpendicular to the first axis.
In a second embodiment the ear piece and the support arm are connected by a ball and socket joint.
