A loudspeaker driver (22) also suitable for compound applications comprising a rigid speaker frame (11, 13, 15, 19, 8) to which is attached a permanent magnet (13) with which a voice coil winding (9) is adapted to interact through electromagnetic force. The voice coil winding (9) is adapted to deliver axial motion to a diaphragm assembly (21), which includes an elastic outer section (2), whose outer rim (5) is attached to the outer part of the speaker frame (11). The diaphragm assembly (21) comprises an essentially rigid primary vibrating diaphragm (4) attached between the elastic outer section (2) and an elastic inner section (3), whose inner rim (10) is attached to the inner part of said speaker frame (8). Said voice coil winding (9) is fixed to the primary vibrating diaphragm (4) through said voice coil former (6), which is adapted to move said diaphragm assembly (21). |
