Title:
ACOUSTIC RADIATOR WITH A BAFFLE OF A DIAMETER AT LEAST AS LARGE AS THE OPENING OF THE SPEAKER ENCLOSURE TO WHICH IT IS MOUNTED
Document Type and Number:
WIPO Patent Application WO2002085064
Kind Code:
A3
Abstract:
Several different acoustic radiator designs improve performance over the prior art while providing a larger baffle (cone)(22), a lesser volume of air displaced than by the smaller prior art speaker design, while maintaining the same enclosure mouth (2) diameter and allowing the use of a shallower enclosure (2). The advantages are achieved in a variety of ways with several configurations that include: a substantially vertically oriented resilient mount (24, 30) for the baffle (cone) where that resilient mount is entirely beneath the outer edge of the baffle (cone)(22), between the outer rim of the baffle (cone) and the outer flange of the basket; a resilient (24, 30) that resembles prior art surround (14) rotated outward by 45 DEG to 70 DEG extending the outer edge of the baffle (cone)(22) outward allowing the use of a larger diameter speaker baffle (cone); and surround mounted to the outer flange of the basket (4) beneath the dome of the surround moving the surround outward from the center of the enclosure (2) allowing for a larger diameter baffle (cone) in an enclosure with the same mouth size provided by prior art speakers and passive radiators.
