<p>The system has a number of units (2), each with an electronic controller (4), a memory (5) with data corresp. to acoustic signals, a receiver (6) for receiving control data, a conversion device (7) for converting parts of the stored data selected using the control signals into acoustic signals and a sound generator (8). The sound generator reproduces the acoustic signals. A central unit (1) contains a controller (9) for generating control data and a transmitter (10) which transmits the control data to a number of selected units (2).</p> |
