Abstract A sound receiver head set or ear phone includes an ear piece housing of generally semi-spherical shape having an annular padded edge which is adapted to be located against the head of a user around the ear. The housing defines a guide for a transducer system which has an acoustic inlet which may be oriented at a selected location in respect to the auditory meatus of the wearer. The housing carries adjusting means for regulating the position of the transducer and the acoustic outlet so that it is at a desired spacing or gap from the ear. The guide way defined in the housing for the transducer is advantageously oriented at an optimum angle in respect to the ear of the wearer in respect to a tangent to the head of the wearer and in addition the adjustable means permits its inner and outer movement in respect to the ear for the precise definition of the volume of an interreaction gap defined between the acoustic outlet of the transducer and the auditory meatus of the ear.
An earphone comprising a casing adapted to be positioned over an ear of a listener and having an internal cage therein defining a guideway for a transducer mounted in said guideway, said guideway being movable in directions toward and away from the ear of the wearer, said transducer having an acoustic outlet at the end directed toward said ear which will shift with said transducer when the said guideway is moved to vary the volume of the spacing between the said transducer and the ear of the wearer, and a flexible interior wall in said casing, said guideway being connected to said wall and being displaceable with said wall for varying the position of said transducer.

An earphone comprising a casing adapted to be positioned over an ear of a listener and having an internal cage therein defining a guideway for a transducer mounted in said guideway, said guideway being movable in directions toward and away from the ear of the wearer, said transducer having an acoustic outlet at the end directed toward said ear which will shift with said transducer when the said guideway is moved to vary the volume of the spacing between the said transducer and the ear of the wearer, and a flexible interior wall in said casing, said guideway being connected to said wall and being displaceable with said wall for varying the position of said transducer.
Claim 3
Dependent Claim

An ear phone, according to claim 1, wherein said wall comprises a rubber diaphragm which at least partly defines the volume of the interreaction gap between said acoustic outlet and the wearer''s ear, said diaphragm forming a resilient element for restoring the transducer system to an initial position.
