Moving Boundary Condition and Nonlinear Propagation as the Sources of Nonlinear Distortion in Loudspeakers

Document Thumbnail

Two natural phenomena connected with the excitation of acoustic waves by moving the loudspeaker diaphragm are considered: 1) effect of a moving boundary condition traditionally named the Doppler effect; and 2) effect of nonlinear propagation of acoustic waves. In this paper, it is shown that distortions caused by nonlinear propagation have negligible magnitude; and that an improved expression for the coefficient of Doppler-type distortions is derived. A concept of an anti-Doppler filter is presented.
