Patent number: 11889263Abstract: A loudspeaker described herein have a radiation pattern which is constant over a wide frequency range without requiring any attenuation. The system includes plurality of drivers not uniformly arranged so that the relative velocity of the speaker follows the Legendre shading function. By making the driver density proportional to the Legendre function SSCBT allows each driver to play at max volume. The purpose behind Space Shaded Constant Beamwidth Transducer (SSCBT) is to replace attenuation with incremental spacing between the drivers. Alternatively, the angles each driver is placed by doubling the distance each driver is placed to accomplish the region which is 3 db lower. When the distance is doubled, the angle between each driver increases the further from 0 it is and is consistent with the Legendre function on its surface.Type: GrantFiled: August 17, 2021Date of Patent: January 30, 2024Inventor: Paul Sonifrank
