| 摘要 |
The invention relates to a speaker having a sound emission direction, comprising: a cage (6); a membrane system having a membrane constructed as a sandwich and becoming thicker from the inside to the outside, an internally wound vibrating coil (16) mounted on a carrier (3) in the center and at the height of the membrane (1), wherein the membrane (1) is connected to the carrier (3), a first centering feature (2) implemented particularly sinusoidal in cross section and centering the membrane in the cage (6) in a first plane, and a second centering feature (4) implemented particularly sinusoidal in cross section and connected to the carrier (3) of the vibrating coil (16) and centering the membrane (1) in a second plane by means of the carrier (3); a symmetrically constructed stray field magnet system (7) comprising two magnets (9) having opposite pole orientation and a pole plate (8) disposed centered between the two magnets, wherein the stray field magnet system (7) centrally permeates the membrane, the vibrating coil (16) is located at the height of the pole plate (8) in the non-displaced state, and the stray field magnet system (7) is disposed centered relative to the cage (6); and a center pleat (11) forming a closed and flexible connection between the stray field magnet system (7) and the membrane system (1, 3, 16). |
