Abstract
An omnidirectional sound source is formed by mounting a loudspeaker in an enclosed baffle, preferably formed as a low profile hemi-spherical, convex cap with a small circular orifice at its apex and a planar base. The loudspeaker is mounted within the baffle, affixed to the underside of the baffle cap directly beneath the orifice. Substantially plane audio-frequency wavefronts emanating from the immediate vicinity of the loudspeaker diaphragm pass through the orifice and, by the process of diffraction emerge as spherical waves. The spherical wavefronts follow the smooth, axisymmetric, gently curved contour of the low-profile, hemispherical baffle and are not distorted by edge effects where the baffle joins its planar base. As a result, an omnidirectional sound source is obtained.
