Technical requirements for acoustic couplers book   Acoustic Coupler: An acoustic coupler is an audio interface device for coupling a computer with audio into or out of a telephone.

It may also be a terminal device linking data terminals and radios with telephone networks. The link or interface is done by picking up audio signals from a telephone handset rather than a direct electrical connection.

Acoustic couplers were still used until at least the late s by people travelling in areas of the world where electrical connection to the telephone network is illegal or impractical.
