An acoustic coupler for a data communication device with a housing having a receiver and a coupling member mechanically coupling the receive housing and the transmitter housing. The acoustic coupler also includes a first microphone as part of the receiver for receiving an acoustic signal from a transmitter portion of a handset of a telephone, when the acoustic coupler is set to the handset. A first speaker is fastened to the second end of the receive part and outputting an acoustic signal to an operator, with yet a second speaker being fastened receiver portion of the housing for outputting an acoustic signal to a receiver portion of the handset. A second microphone is fastened to another part of the receiver which is for inputting an acoustic signal from the operator, and a coupling circuit for electrically coupling the first microphone, the second microphone, the first speaker and the second speaker to a data transmission apparatus. This arrangement allows for a more reliable connection of a data transmission device to the communication medium, be it radio or wired.
