摘要 |
Loudspeaker for an acoustic enclosure, notably a tweeter or medium, incorporates a spherical membrane (2) with direct radiation as its dome, with a surface concave with respect to the coil (3) and on which, preferably, is fixed at a certain level of the plane (A-B), for example at mid-height, the mobile coil in order to assure an optimal mechanical coupling capable of reproducing frequencies below 1 kHz with an elevated yield. Independent claims are also included for: (a) fabrication of tweeter or medium domes; (b) a tool for forming thin metal sheets for the fabrication of three dimensional components during the fabrication of these domes; (c) a dome for a loudspeaker of an acoustic enclosure, notably for a tweeter or medium; and (d) an acoustic enclosure incorporating at least one such loudspeaker. |
