A telephone desk set 1 is disclosed, the desk set comprising a touch screen 2, a base (4, Fig. 3) which supports the touch screen, a holder (i.e. cradle) 20 for a telephone handset 3, and a microphone 22 for hands-free operation. The touch screen is upstanding from the base, the holder is adjacent to the touch screen, and the microphone is located in a channel (23, Figure 5a & 5b) between the screen and the holder. The channel defined by the edge of the screen and the edge of the holder may define a waveguide for sound reaching the microphone. This may help to avoid feedback to the microphone, for example of output from loudspeakers 17 of the set reflected back to the microphone from an object (e.g. person) in front of the desk set, while making use of existing components of the desk set. The microphone may be located behind a hole in the channel and may therefore be recessed with respect to the screen and the holder. The loudspeaker(s) may be located in the base and below the screen such that the microphone is located rearwards of the speaker(s). The hole and waveguide channel are of the order of millimetres in dimensions. |
