Abstract

In a sound reproduction device (1), an output terminal (2) to which a sound transducer (3) is attachable, an amplification device (200), and a control device (100) are provided. The amplification device (200) has an output point (210) which is coupled to the output terminal (2). A sound level can be provided by a sound transducer (3) connected to the output terminal (2) in accordance with a specific voltage at the input opening (30, 31, 32) of the sound transducer (3) when the sound reproduction device (1) is in operation. The control device (100) can calibrate an amplification of the amplification device (200) as a function of the dependence of the sound level on the voltage at the input point (30, 31, 32) of the sound transducer (3). For this purpose, the control device (100) has a measuring device (120) with a signal source (130) to provide a source signal and a measuring device (140) for the recording of a measuring signal as a function of the source signal. Both said signal source and said measuring device are coupled to the output terminal (2). The measuring device (120) is set up to determine at least one parameter for the sound transducer (3) in accordance with the measuring signal, from which parameter the dependence of the sound level can be derived from the voltage at the input point (30, 31, 32) of the sound transducer (3).
