Abstract
An acoustic mounting and coupler, for coupling a transducer of a handset to a transducer of a terminal or similar form of apparatus, such as a visual display terminal for deaf users, has a flexible tubular member attached to the housing of the terminal. At the upper end of the tubular member is a flexible disc having a plurality of readily deformable annular ribs. The tubular member provides for vertical movement and some tilting. The ribs give good air sealing between the handset and coupler. Ambient noise input is reduced and mechanical vibration to the transducer in the terminal is also reduced. Some degree of variation in geometry and dimensions of the handset can be accommodated. Some laxity in placement of the handset can also be accommodated.
