Abstract
Abstract Apparatus is disclosed for acoustically coupling a telephone to a data terminal for the purpose of transmitting or receiving messages, where the telephone handset is placed on a bracket mounted directly on the chassis of the terminal. Isolation of transmitting and receiving acoustic links is provided by a pair of resilient cups, one for each link. The inside contour of each cup is adapted to provide a supporting annular ledge for one end of the telephone and an airtight seal over the transducer thereof. An annular recess below the ledge is formed to receive and tightly hold a flange of a receiving or transmitting transducer. Each cup is mounted on the bracket by a resilient flange. The flange is connected to the cup by a sleeve which is turned in at the top to form an inverted auxiliary cup with the base of the main cup protruding through the bottom of the auxiliary cup. In that manner, virtually complete acoustic isolation is provided by the cup from the surrounding air and bracket.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
203 words
Apparatus for acoustically coupling a telephone to a data terminal for the purpose of transmitting or receiving messages via a data coupling unit, comprising: a bracket for holding a telephone handset, said bracket being mounted directly on the chassis of said terminal or some integral part thereof; a pair of resilient cups, one cup for each end of said handset, the inside contour of a given cup being adapted to provide support for one end of said handset and to provide an acoustic seal over the telephone transducer thereof, each cup having an eternal flange attached to said bracket, said flange of a given one of said cups being connected thereto by a resilient sleeve turned in at the top for connection to the outside of said given one of said cups, thereby forming an inverted auxiliary cup to allow the axis of said given one of said cups to be free to move in any direction as a result of shock or sound waves; and a complementary pair of transducers, each secured inside a different one of said cups, a given transducer being electrically connected to said coupling unit by leads passing through a wall of said given one of said cups.
Claim 2
Dependent Claim
203 words
Apparatus for acoustically coupling a telephone to a data terminal for the purpose of transmitting or receiving messages via a data coupling unit, comprising: a bracket for holding a telephone handset, said bracket being mounted directly on the chassis of said terminal or some integral part thereof; a pair of resilient cups, one cup for each end of said handset, the inside contour of a given cup being adapted to provide support for one end of said handset and to provide an acoustic seal over the telephone transducer thereof, each cup having an eternal flange attached to said bracket, said flange of a given one of said cups being connected thereto by a resilient sleeve turned in at the top for connection to the outside of said given one of said cups, thereby forming an inverted auxiliary cup to allow the axis of said given one of said cups to be free to move in any direction as a result of shock or sound waves; and a complementary pair of transducers, each secured inside a different one of said cups, a given transducer being electrically connected to said coupling unit by leads passing through a wall of said given one of said cups.
Claim 3
Dependent Claim
20 words
Apparatus as defined in claim 1 wherein said given cup, flange and sleeve are formed of the same resilient material.
Claim 4
Dependent Claim
32 words
Apparatus as defined in claim 1 wherein said given cup is provided with an internal ledge of resilient material to space the end of the telephone handset away from said transducer therein.
Claim 5
Dependent Claim
27 words
Apparatus as defined in claim 3 wherein said given cup, flange, sleeve and internal ledge are all formed of the same resilient material as an integral unit.
Claim 6
Dependent Claim
77 words
Apparatus as defined in claim 1 wherein the diameter of said sleeve is selected to be sufficiently large as compared to the outside diameter of said given one of said cups so that said inverted auxiliary cup formed to support said given one of said cups may be turned in at the upper end with a radius at the turn sufficient to cause said sleeve to meet the wall of said given one of said cups perpendicularly.
Claim 7
Dependent Claim
39 words
Apparatus as defined in claim 5 wherein the base of said given one of said cups protrudes into said inverted cup formed by said sleeve for the purpose of providing sufficient depth for a given one of said transducers.
Claim 8
Dependent Claim
51 words
Apparatus as defined in claim 6 wherein the base of said given one of said cups protrudes into said inverted cup a predetermined depth for limiting downward travel of said given one of said cups toward said bracket while a telephone handset is being placed on said pair of resilient cups.
Claim 9
Dependent Claim
193 words
Apparatus for acoustically coupling at least one transducer in one end of a telephone handset to a data terminal for the purpose of transmitting or receiving messages via a data coupling unit, comprising: a bracket for holding said telephone handset, said bracket being Mounted directly on the chassis of said terminal or some integral part thereof; a resilient cup, having thick side and bottom walls made of the same material, for receiving said one end of said telephone handset, the inside contour of said side wall of said cup being adapted to provide support for said one end of said handset and to provide on acoustic seal over the telephone transducer thereof; a flange made of the same material as said cup connecting the outside of said cup to said bracket; and a terminal transducer inside said cup spaced away from said bottom wall and secured to said sidewall all around the inside of said cup to provide an acoustic chamber between said terminal transducer and said bottom wall, said terminal transducer being electrically connected to said coupling unit by leads passing out of said acoustic chamber through a wall of said cup.
Claim 10
Dependent Claim
193 words
Apparatus for acoustically coupling at least one transducer in one end of a telephone handset to a data terminal for the purpose of transmitting or receiving messages via a data coupling unit, comprising: a bracket for holding said telephone handset, said bracket being Mounted directly on the chassis of said terminal or some integral part thereof; a resilient cup, having thick side and bottom walls made of the same material, for receiving said one end of said telephone handset, the inside contour of said side wall of said cup being adapted to provide support for said one end of said handset and to provide on acoustic seal over the telephone transducer thereof; a flange made of the same material as said cup connecting the outside of said cup to said bracket; and a terminal transducer inside said cup spaced away from said bottom wall and secured to said sidewall all around the inside of said cup to provide an acoustic chamber between said terminal transducer and said bottom wall, said terminal transducer being electrically connected to said coupling unit by leads passing out of said acoustic chamber through a wall of said cup.
Claim 11
Dependent Claim
27 words
Apparatus as defined in claim 8 wherein said terminal transducer has an annular flange, and said terminal transducer is secured to said sidewall through said annular flange.
Claim 12
Dependent Claim
41 words
Apparatus as defined in claim 9 wherein said annular flange of said terminal transducer is secured to said sidewall of said cup by annular recess in said sidewall adapted to receive and tightly hold said annular flange of said terminal transducer.
