Method and device for mimicking cat purrs

摘要

Method for mimicking cat purrs, in which a first electromechanical transducer (8) converts an electrical signal (7) into vibrations, characterized in that the electrical signal (7) has a fundamental frequency (28) and is divided into time segments (26), in which the electrical signal (7) is frequency modulated with frequency sweeps (29), which are determined by a random generator.
