FIG. 2 shows the operating state in which the identification carrier 8 was set on the playback device. The identification carrier 8 is placed on the surface 4 of the recess 3 and adheres there by means of the magnets provided in the feet of the identification carrier 8. Identification carrier 8 has an RFID transponder (not shown in detail) (one identifier). As the identification carrier 8 has now been moved into the area of the sensor's surroundings that is monitored by the sensor, it now has a certain characteristic that can be detected by the sensor. The sensor detects the presence of the RFID transponder in the identification carrier 8 and informs the (not further described) control unit by means of a signal. The control unit then controls the speaker to play back audio information without the need to operate any other control element.
The sensor reads an identifier from the RFID transponder of the identification carrier 8 and informs the control unit of this identifier. On the basis of an allocation table (playback device allocation table) stored in the control unit, the control unit allocates the identifier read by the sensor to a specific data record (a media file) containing specific audio information in a memory (not shown in detail) of playback device 1. The control unit then drives the speaker to play back the audio information contained in the specific record (media file) read from the memory by the control unit. This audio information is a piece of music that takes at least 10 seconds to play.
