Dynamic Driver Linearization Using Current Feedback

Document Thumbnail

It is well known that the electromechanical parameters of a dynamic driver can be modified through current feedback to suit the requirements of the available enclosure size and desired bandwidth, with a reduced distortion as a commonly observed beneficial effect. However, especially when designing sealed enclosures it is possible to select the loudspeaker parameters from a continuum of combinations of effective moving mass, damping resistance, and compliance. This paper describes optimization of electrical source parameters to improve the linearity based on numerical solution of the nonlinear equation of motion of the driver using the measured driver parameters.
