The present invention relates to a wireless telephone sound interface device (2, 22), to a wireless telephone sound system (1, 21) and to a method for operating a wireless telephone sound interface device (2, 22). The invention may advantageously be utilized in telephone devices connected to telephone networks (8, 28) and having a base unit (3, 23) wirelessly connected to one or more wireless sound interface devices (2, 22). The present invention provides a wireless telephone sound interface device (2, 22) comprising an electronic circuit (42-49), a first wireless transceiver (44) adapted to exchange audio signals with a base unit (3, 23) through a wireless audio connection (4, 24) and a device controller (41) adapted to detect a disconnection of the wireless audio connection (4, 24) and to control the electronic circuit (42-49) in dependence on detecting said disconnection. The wireless telephone sound interface device (2, 22) is characterized in that the device controller (41) further is adapted to estimate a disconnection cause for said disconnection and to control the electronic circuit (42-49) in dependence on the estimated disconnection cause. This may allow the wireless telephone sound interface device (2, 22) to avoid superfluously alerting the user of a disconnection deliberately caused by the user and may thus aid in reducing daily annoyance of the user and/or of colleagues in a working environment. |
