Abstract
Abstract A rubber-like housing for an acoustic coupler adapted to couple a telephone handset to a transducer for data communication. The configuration and material makeup of the housing insures intimate contact with the telephone handset. The upper portion of the housing is of rigid elastic material and somewhat elongated to completely secure the handset into a gripping position; whereas the lower portion of the housing is made up of relatively thin elastic material acting as a shock absorber. The upper and lower portion is separated by a continuous indentation. The durometer of the material and the indentation permits omnidirectional movement of the handset without affecting the coupling or its operation. A pair of such housings are oriented in an enclosure at an angle similar to the standard telephone to readily receive and immediately seal in position the telephone handset.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
277 words
An acoustic coupler for coupling a transducer to a telephone handset for data communication, a pair of shock absorbing means for positioning said telephone handset to said transducer, each means comprising: a housing having a circular upper portion and a circular lower portion, the diameter of said upper portion being as great as the outside diameter of said lower portion, an opening in said upper portion of a diameter decreasing from a diameter greater than to a diameter less than that of telephone mouth and earpiece to receive and forcibly retain said telephone mouth and earpiece in a shock absorbing acoustical relationship to said transducer, an opening intermediate said lower portion and said upper portion for housing a transducer, means integrally joining together said upper portion and said lower portion, said means including an annular member of a diameter less than the diameter of said upper and lower portions, said annular member turned out at its top to connect to the outside wall of said upper portion and turned out at its bottom to connect to the outside wall of said lower portion, said housing having a highly flexible material makeup and wherein said upper portion and said turned out top part of said annular member has a material thickness greater than said lower portion and said turned out bottom part of said annular member, said openings in said upper portion for receiving said telephone of a diameter greater than the diameter of said annular member, whereby said flexible material, said different thickness flexible material, and said annular joining means provides an omnidirectional and up and down variation in position of said coupler and said telephone handset.
Claim 2
Dependent Claim
277 words
An acoustic coupler for coupling a transducer to a telephone handset for data communication, a pair of shock absorbing means for positioning said telephone handset to said transducer, each means comprising: a housing having a circular upper portion and a circular lower portion, the diameter of said upper portion being as great as the outside diameter of said lower portion, an opening in said upper portion of a diameter decreasing from a diameter greater than to a diameter less than that of telephone mouth and earpiece to receive and forcibly retain said telephone mouth and earpiece in a shock absorbing acoustical relationship to said transducer, an opening intermediate said lower portion and said upper portion for housing a transducer, means integrally joining together said upper portion and said lower portion, said means including an annular member of a diameter less than the diameter of said upper and lower portions, said annular member turned out at its top to connect to the outside wall of said upper portion and turned out at its bottom to connect to the outside wall of said lower portion, said housing having a highly flexible material makeup and wherein said upper portion and said turned out top part of said annular member has a material thickness greater than said lower portion and said turned out bottom part of said annular member, said openings in said upper portion for receiving said telephone of a diameter greater than the diameter of said annular member, whereby said flexible material, said different thickness flexible material, and said annular joining means provides an omnidirectional and up and down variation in position of said coupler and said telephone handset.
Claim 3
Dependent Claim
277 words
An acoustic coupler for coupling a transducer to a telephone handset for data communication, a pair of shock absorbing means for positioning said telephone handset to said transducer, each means comprising: a housing having a circular upper portion and a circular lower portion, the diameter of said upper portion being as great as the outside diameter of said lower portion, an opening in said upper portion of a diameter decreasing from a diameter greater than to a diameter less than that of telephone mouth and earpiece to receive and forcibly retain said telephone mouth and earpiece in a shock absorbing acoustical relationship to said transducer, an opening intermediate said lower portion and said upper portion for housing a transducer, means integrally joining together said upper portion and said lower portion, said means including an annular member of a diameter less than the diameter of said upper and lower portions, said annular member turned out at its top to connect to the outside wall of said upper portion and turned out at its bottom to connect to the outside wall of said lower portion, said housing having a highly flexible material makeup and wherein said upper portion and said turned out top part of said annular member has a material thickness greater than said lower portion and said turned out bottom part of said annular member, said openings in said upper portion for receiving said telephone of a diameter greater than the diameter of said annular member, whereby said flexible material, said different thickness flexible material, and said annular joining means provides an omnidirectional and up and down variation in position of said coupler and said telephone handset.
Claim 4
Dependent Claim
277 words
An acoustic coupler for coupling a transducer to a telephone handset for data communication, a pair of shock absorbing means for positioning said telephone handset to said transducer, each means comprising: a housing having a circular upper portion and a circular lower portion, the diameter of said upper portion being as great as the outside diameter of said lower portion, an opening in said upper portion of a diameter decreasing from a diameter greater than to a diameter less than that of telephone mouth and earpiece to receive and forcibly retain said telephone mouth and earpiece in a shock absorbing acoustical relationship to said transducer, an opening intermediate said lower portion and said upper portion for housing a transducer, means integrally joining together said upper portion and said lower portion, said means including an annular member of a diameter less than the diameter of said upper and lower portions, said annular member turned out at its top to connect to the outside wall of said upper portion and turned out at its bottom to connect to the outside wall of said lower portion, said housing having a highly flexible material makeup and wherein said upper portion and said turned out top part of said annular member has a material thickness greater than said lower portion and said turned out bottom part of said annular member, said openings in said upper portion for receiving said telephone of a diameter greater than the diameter of said annular member, whereby said flexible material, said different thickness flexible material, and said annular joining means provides an omnidirectional and up and down variation in position of said coupler and said telephone handset.
Claim 5
Dependent Claim
35 words
The acoustic coupler of claim 1 wherein said opening of decreasing diameter further comprises an upper bevelled edge and said decreasing diameter extends from said bevelled edge to the uppermost part of said lower portion.
Claim 6
Dependent Claim
24 words
The acoustic coupler of claim 1 wherein said flexible material is a molded composition rubber having a resonant frequency substantially different than the acoustical.
Claim 7
Dependent Claim
