Abstract
Abstract A spectacle mounted directional responsive hearing aid includes various hearing aid components carried in an earpiece of the spectacles. An elongated hollow sound conduit extends over a major portion of the longitudinal length of the earpiece, one end of the conduit communicating with a microphone enclosed in the earpiece and the other end of the conduit opening to the front of the spectacle lens carrying frame in a plane substantially tangent to the hearing aid user''s forehead. The conduit is dimensioned to increase the frequency response of the hearing aid in a predetermined frequency range.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
281 words
A spectacle mounted hearing aid construction comprising the combination of a lens carrying frame adapted to be worn on the front face of the user, said lens carrying frame being independent of any electrical components of the hearing aid, an elongated temple earpiece member attached to each side of the lens carrying frame for supporting the frame on the head of the user, at least one of said temple earpiece members carrying a complete hearing aid circuit including a microphone, a receiver, an amplifier and an electrical power source, said microphone being positioned within said earpiece member adjacent an ear of the user in spaced relationship with said frame, at least one of said temple earpiece members carrying a complete hearing aid circuit including a microphone, a receiver, an amplifier and an electrical power source, said microphone being positioned within said earpiece member adjacent an ear of the user in spaced relationship with said frame, a hollow elongated sound conduit carried by and extending longitudinally over a substantial portion of the length of said earpiece member, one end of said conduit communicating with the input to said microphone and the other end of said conduit terminating in an aperture at the front end of said temple earpiece member opening in a direction forward of and in substantially the same direction that the head of the user is facing, said lens carrying frame having an aperture in axial alignment with the aperture at the front end of said temple earpiece member to provide a substantially continuous sound conducting passage through said frame and earpiece member to the microphone when said spectacle mounted hearing aid is in operative poSition on the user''s head.
Claim 2
Dependent Claim
281 words
A spectacle mounted hearing aid construction comprising the combination of a lens carrying frame adapted to be worn on the front face of the user, said lens carrying frame being independent of any electrical components of the hearing aid, an elongated temple earpiece member attached to each side of the lens carrying frame for supporting the frame on the head of the user, at least one of said temple earpiece members carrying a complete hearing aid circuit including a microphone, a receiver, an amplifier and an electrical power source, said microphone being positioned within said earpiece member adjacent an ear of the user in spaced relationship with said frame, at least one of said temple earpiece members carrying a complete hearing aid circuit including a microphone, a receiver, an amplifier and an electrical power source, said microphone being positioned within said earpiece member adjacent an ear of the user in spaced relationship with said frame, a hollow elongated sound conduit carried by and extending longitudinally over a substantial portion of the length of said earpiece member, one end of said conduit communicating with the input to said microphone and the other end of said conduit terminating in an aperture at the front end of said temple earpiece member opening in a direction forward of and in substantially the same direction that the head of the user is facing, said lens carrying frame having an aperture in axial alignment with the aperture at the front end of said temple earpiece member to provide a substantially continuous sound conducting passage through said frame and earpiece member to the microphone when said spectacle mounted hearing aid is in operative poSition on the user''s head.
Claim 3
Dependent Claim
37 words
A spectacle mounted hearing aid construction in accordance with claim 1 wherein the dimensions of the earpiece member sound conduit are preselected for optimizing the frequency response of the hearing aid in a predetermined range of frequencies.
