Abstract (en)

[origin: EP0022937A1] 1. Loudspeaker with multiway diaphragm which - is suspended from the front edge of a loudspeaker basket (chassis) (13) by means of the spring (9), - is driven by a moving coil (14), - is composed of concentric diaphragm elements (4, 5, 6) which are themselves connected to each other by means of the spring couplings (7, 8), - in which the various spring-mass-elements (4, 5, 6, 7, 8, 9) are connected - similar to a mechanical loudspeaker-dividing network - in such a way that with high frequencies only the high-frequency diaphragm element (4) will oscillate, whereas with lower frequencies those diaphragm elements lying further on the outside (5, 6) will be coupled into the oscillation, characterized by - an arrangement of multiway springs (1, 2, 3, 10, 11, 12) - suspended from the back of the loudspeaker basket (13) - its spring couplings (10, 11, 12) being mounted copolonar - and between the spring couplings (10, 11, 12) of which supports (1, 2, 3) are fitted, which are rigidly connected to the corresponding diaphragm elements (4, 5, 6) (ill. 1, 2).
