ABSTRACT:
A headphone having a dual element speaker unit including a face plate having an opening generally centrally located therein. A case coupler is mounted in the opening, and has an annular projection protruding through the opening. A first dynamic transducer is mounted within that annular projection. A second dynamic transducer is mounted to the case coupler opposite the first transducer. The case coupler includes an isolating plate, positioned between the first and second transducers, for sonically isolating the first transducer from the second. A grill plate is mounted over the annular projection, for providing a load to the first transducer. The isolating plate includes an opening, located outside the periphery of the annular projection, for allowing the passage of sound from the second transducer to the listener. A support assembly is connected to the face plate, and a cup assembly in turn connected to the support assembly. The support assembly includes means for allowing relative pivoting movement between the cup assembly and the face plate. The support assembly includes a ball and socket arrangement resulting in the relative motion allowed between the cup assembly and the face plate being biaxial. A bellows member is positioned between the cup and the face plate for damping movement between the cup assembly and the face plate, and for enclosing and directing sound waves generated by the transducers. A unique plug arrangement is provided for connecting the cord to the headphone apparatus.
