- W2043715926 abstract "The exact theory for the radiation of a small loudspeaker in the surface of a rigid circular disk of elliptic profile is presented. Numerical results are included for a monopole at the center of the disk and on its surface. The solution for the loudspeaker in the center of a free circular baffle is then formulated by superimposing the solution of a positive source on one side of the baffle with that for a negative source on the other side. For wavelengths greater than the circumference of the baffle, the resulting field turns out to be very similar to that of a dipole of finite dipole axis. However, for wavelengths smaller than the diameter of the baffle, the diffraction field is shown to be dominated by edge effects. In particular, the total field may also be represented by a simple ring−point source combination, i.e., the edge of the baffle is essentially replaced by a ring source. It is shown that in the vicinity of the axis of the baffle, the shape of the frequency response curve depends little on how much volume flow is generated on the opposite side of the baffle. In other words, it makes little difference (except in absolute level) whether a loudspeaker is enclosed in a box or is permitted to radiate from the rear. Subject Classification: 20.15, 20.30, 20.55." @default.
