An electronic device is provided comprising a printed circuit board (12) with electronics for controlling main functions of the electronic device (10) and an external housing (11) enclosing the printed circuit board (12) and internal parts of the electronic device (10). The device further comprises a proximity sensor (21, 31, 41) mounted on the printed circuit board (12) and arranged for providing a signal depending on variations in a proximity of a predetermined local part of the external housing (11) to the printed circuit board (12). A control circuit (26) is coupled to the proximity sensor (21, 31, 41) and is arranged to detect, based on the signal, when the external housing (11) is tapped on by a user. |
