Abstract (en)
An adaptive bending transducer has a baseplate (2) that shifts an audio signal by oscillating. An actuator (3) on the baseplate is controllable to swing the baseplate based on an information signal (N) e.g. sinusoidal sweep signal having different information signal frequencies. A controller (4) adjusts the natural frequency of the bending transducer based on the information signal frequency.
