Ear receiver

An apparatus for positioning a transducer in close proximity to the human ear, the transducer being of the type which produces audible sound in response to an input signal, comprising:

• a housing carrying the transducer and having an exterior opening through which audible sound from the transducer radiates;
• a support arm connected to the housing, the support arm being substantially linear and having a first end connected to the housing and a second end extending away from the housing in a direction substantially parallel to the housing exterior opening;
• an ear piece formed to fit around the pinna of a human ear;
• an L-shaped member connecting the support arm to the ear piece, the L-shaped member having a first end fictionally and rotatably connected to the second end of the support arm for rotation about a first axis which is substantially parallel to the support arm and a second end fictionally and rotatably connected to the ear piece to permit rotation of the ear piece about a second axis which is substantially perpendicular to the first axis;
• limiting means for limiting rotation of the L-shaped member about the first axis to an angle less than 360.degree.;
• and
• signal delivery means for delivering the input signals to the transducer.

An ear receiver of the type carried by the pinna of the human ear, comprising:

• a housing having an exterior front opening;
• a transducer adapted to receive an input signal and responsively produce audible sound, the transducer being mounted in the housing such that the audible sound produced by the transducer radiates through the housing exterior opening;
• a support arm connected to the housing, the support arm being substantially linear and having a first end connected to the housing and a second end extending away from the housing in a direction substantially parallel to the housing exterior front opening;
• an ear piece formed to fit around the pinna of a human ear, the ear piece having a first end movably connected to the second end of the support arm for rotation over a range of at least 180.degree. about each of two axes, a first axis being substantially perpendicular to the housing front opening and a second axis being substantially parallel to the housing front opening;
• an L-shaped member connecting the support arm to the ear piece, the L-shaped member having a first end frictionally and rotatably connected to the second end of the support arm for rotation about the first axis and a second end frictionally and rotatably connected to the first end of the ear piece for rotation about the second axis;
• and
• signal delivery means for delivering the input signals to the transducer.

An ear receiver of the type carried by the pinna of the human ear, comprising:

• a housing having generally dish-shaped back wall and a connecting bracket extending from the housing back wall, the housing defining an interior compartment terminating in a generally planar front opening opposite the back wall;
• a transducer adapted to receive an input signal and responsively produce audible sound, the transducer being mounted in the housing interior compartment such that the audible sound produced by the transducer radiates from the housing front opening;
• a substantially linear support arm connected to the housing, the support arm having a first end slidably connected to the housing back wall at a location substantially opposite the housing front opening and a second end extending away from the housing in a direction substantially parallel to the housing from opening, the support arm including a longitudinal inner bore opening to an outer slot, the connecting bracket slidably engaging in the outer slot and bore to permit longitudinal sliding movement of the housing relative along at least a portion of the support arm;
• an ear piece formed to fit around the pinna of a human ear, the ear piece having a first end movably connected to the second end of the support arm for rotation over a range of at least 180.degree. about first axis which is substantially perpendicular to the housing front opening and over a range of at least 180.degree. about a second axis which is substantially parallel to the housing front opening;
• and
• at least one electrical conductor extending from the bottom of the housing and being adapted to deliver input signals to the transducer.
