SIGNAL PROCESSING METHOD, SIGNAL PROCESSING SYSTEM AND SPEAKER SYSTEM

Abstract

An acoustic processing system includes a signal processor configured to determine an input voltage based on a target parameter, which includes a volume velocity at a sound aperture for sound radiation using Helmholtz resonance, using a nonlinear model where the nonlinear model simulates a relationship in which an acoustic resistance at the sound aperture depends on the volume velocity at the sound aperture; and includes a voltage supplier configured to deliver the input voltage to a loudspeaker device.
