THERMOACOUSTIC SOUND TRANSDUCER DEVICE, AUDIO SIGNAL PROCESSING APPARATUS FOR A THERMOACOUSTIC SOUND TRANSDUCER, AND METHOD FOR CONTROLLING A SOUND TRANSDUCER

摘要

The invention relates to an audio signal processing apparatus (10) for a thermoacoustic sound transducer (20), the audio signal processing apparatus being designed to receive an audio signal (11) and to generate a control signal (12) for the thermoacoustic sound transducer (20) on the basis of the audio signal, wherein: the control signal also has an offset (62); the offset is a time-variable offset (62); and the audio signal processing apparatus (10) is designed to determine the time-variable offset, at least in parts, on the basis of the amplitude curve of the audio signal. The invention further relates to a thermoacoustic sound transducer device (30), comprising an audio signal processing apparatus (10) of this type and a thermoacoustic sound transducer (20), and to a method (100) for controlling a thermoacoustic sound transducer (20).
