| 摘要 |
The invention relates to a speaker with a sound radiation direction, comprising: a basket (6), a membrane system with a sandwich-like membrane (1) that becomes thicker from the outside inwards, an oscillation coil (16) that is mounted in the center and at the level of the membrane (1) on a support (3), and wound inwards, with the membrane (1) being connected with the support (3), a first centering (2), especially one with a sinusoid shape in cross section, which centers the membrane (1) in the basket (6) in a first plane, and a second centering (4), especially one with a sinusoid shape in cross section, which is connected with the support (3) of the oscillation coil (16) and centers the membrane in a second plane via the support (3), a symmetrically designed stray field magnet system (7) with two magnets (9) with opposingly-oriented poles and a pole plate (8) centrally placed between the two magnets, wherein the stray field magnet system (7) centrally penetrates the membrane (1), the oscillation coil (16) is at the level of the pole plate (8) in its non-deployed state, and the stray field magnet system (7) is situated in centered fashion to the basket (6), and a centered lip (11), which forms a closed and flexible connection between the stray field magnet system (7) and the membrane system (1, 3, 16). |
