Augmented passive radiator loudspeaker

摘要: A resonant loudspeaker system which produces improved reproduction of low frequency sound comprises a coupling chamber encloses the rear driver and contains two additional openings in are suspended diaphrams free to move but coupled together so that forces on them opposition. One is baffled other radiate. The air when excited by can only act upon difference areas diaphrams, radiation produced determined unbaffled area. from thus amplified permitting an combination response, distortion, electrical efficiency physical size be achieved.
