METHOD AND SYSTEM FOR NONLINEAR CONTROL OF MOTION OF A SPEAKER DRIVER

Title:

METHOD AND SYSTEM FOR NONLINEAR CONTROL OF MOTION OF A SPEAKER DRIVER

Document Type and Number:

WIPO Patent Application WO/2019/143150

Kind Code:

A1

Abstract:

One embodiment provides a vented box loudspeaker system comprising a speaker driver and a controller configured to receive a source signal for reproduction via the driver, determine a target displacement of the driver and a target sound pressure based on a first physical model of the system, and generate a control voltage based on the target displacement, the target sound pressure, and a second physical model of the system. Another embodiment provides a passive radiator loudspeaker system comprising an active speaker driver and a controller configured to receive a source signal for reproduction via the driver, determine a target displacement of a component based on a first physical model of the system, and generate a control voltage based on the target displacement and a second physical model of the system. In both embodiments, an actual displacement of the driver during the reproduction is controlled based on the generated control voltage.
