摘要： Coaxial loudspeaker arrangement with an outer diaphragm (21) for operating in a lower frequency range, an inner diaphragm (23) for operating in a higher frequency range, both located in a common loudspeaker frame (10), with an outer voice coil (22) connected to the outer diaphragm (21), an inner voice coil (24) connected to the inner diaphragm (23), two coaxially arranged magnets (31, 32), and ferrite cores (41, 42, 43) in association with the magnets, wherein the voice coils (22, 24) extend into air gaps (51, 52) between the ferrite cores, and the diaphragms are connected to the loudspeaker frame (10) through flexible suspending elements (1 1-14). In the proposed loudspeaker, an inner core (41) and an outer core (42) separated from each other by an inner air gap (52), is located between an outer magnet (31) and an inner magnet (32); one ferrite core (43a) of the outer magnet (31 ) is separated by an outer air gap (51) from the outer core (42) located between the two magnets, wherein the voice coil (22) of the outer diaphragm (21) extends into the outer air gap (51) and the voice coil (24) of the inner diaphragm (23) extends into the inner air gap (52).
