1. A coaxial (1) two-way or more loudspeaker system comprising a main electro-dynamic transducer (2) for the reproduction of low range and/or mid range frequencies, including:
a main magnetic circuit (4) defining a main air gap (17), a moving part (22) comprising a diaphragm (23) fixed to a movable coil (24) diving into the main air gap (17), said movable coil (24) comprising a support (26) and a solenoid (25) winded onto the support (26); wherein the system further comprises a secondary electro-dynamic transducer (3) for high range frequencies, mounted in a coaxial and frontal position with respect of the main electro-dynamic transducer (1), received within a space limited backwards by a front face (11) of a pole piece (6) of the main magnetic circuit (4), and laterally by the wall of the support (26) of the movable coil (24) and including: a secondary magnetic circuit (34) distinct from the main magnetic circuit (4) and defining a secondary air gap (47), a moving part (48) comprising a diaphragm (49) fixed to a movable coil (50) diving into the secondary air gap (47), and a waveguide (76) forming a whole horn, mounted in the vicinity of the diaphragm (49), and having a face (80) facing and in the vicinity of the diaphragm and limiting a compression chamber (93), said waveguide (76) having a mouth (88) which extends further to a peripheral suspension (27) of the diaphragm (23) of the main transducer (2) wherein the secondary transducer (3) further comprises a fixed endoskeleton (52), and wherein the moving part (48) of the secondary transducer is mounted to the endoskeleton (52) by an inner suspension (66) disposed inside the diaphragm (49), wherein the moving part (48) of the secondary transducer (3) is free of outer suspension outside the diaphragm (49). |
