Pocket sized telephone line data communication devices which include acoustic coupling capabilities are disclosed. The couplers have a primary body member housing a microphone (or speaker) adjacent one face surface thereof for disposition flat against the ear piece (or microphone) of a conventional telephone handset. A flexible slide structure having a speaker (or microphone) therein is coupled to the body member and is slideable with respect thereto to extend outward to cover the microphone (or earpiece) of the handset, the flexibility of the flexible member together with the slide allowing varying amounts of extension and angularity between the flexible member and the body to accommodate handsets of different spans between and angularity of the earpiece and mouthpiece thereof. With the flexible member at its extreme retracted position, the entire assembly is quite small, readily fitting within a man\s shirt pocket. Various embodiments are disclosed.
