Abstract
A communication device includes a keyboard with key functions and a microphone connected to the outside of the housing of the device by an acoustic path which opens to the outside of the device through one of the keys of the keyboard. The microphone is accommodated either on the inside of the key, or in another arbitrary area inside the device, while still being connected to the acoustic path by an acoustic channel.
