FIG. 3 shows the playback device 1 and an identification carrier 8, which can be placed in a recess 3 of the playback device 1. FIG. 1 also shows a base station 100, which has a projection 101 with a socket 102. On the (not shown) underside of the playback device 1, a recess corresponding to the projection 101 is provided with a plug projecting into the recess. When the playback device 1 with the recess provided on its underside is placed on the projection 101, the (not shown) plug is inserted into the socket 102, thereby creating an electrical connection between playback device 1 and base station 100. The base station 100 may have an electrical connection 103. A (not shown) rectifier may be provided in the base station 100 which converts the alternating current tapped with the plug of the electrical connection 103 into a direct current of the desired magnitude provided at socket 102. Instead of the electrical connection via the (not shown) plug and the socket 102, it is also conceivable that the base station 100 contains a coil for contactless, in particular inductive charging of the playback device 1 and the playback device 1 has a corresponding (not shown) coil.
The base station 100 may contain connectors or connections to other devices, such as speakers, displays or computers, for playing a program. Base station 100 may also contain communication modules, such as communication modules for a WLAN, for Bluetooth, for NFC or a mobile phone network.
