Ring shaped membrane for an electro-acoustical loudspeaker |
| 摘要 |
Ring-shaped membrane for an electro-acoustical loudspeaker, where said membrane comprises two or more dome-shaped annulus concentrically arranged around a central portion through which an imaginary axis of symmetry passes, where an outer periphery of said membrane is suitable to be attached to a surround; where the central portion is attached to a tower, which again is fastened to the loudspeakers driver, wherein the angle between a plane being perpendicular to the axis of symmetry and the attachment of the membrane to the surround resp. the tower is in the interval 0° to 40°, most preferred around 30°. |

1. A ring-shaped membrane for an electro-acoustical loudspeaker, the membrane comprising:
two or more dome-shaped annuluses concentrically arranged around a central portion through which an axis of symmetry passes, the membrane having an outer periphery adapted to be attached to a surround; wherein the central portion of the membrane is attached to a tower connected to a loudspeaker driver, the tower comprising a cavity, and the angle between a plane being perpendicular to the axis of symmetry and the attachment of the membrane to the tower is in the interval 0° to 40°; and wherein the central portion of the membrane is attached to the cavity of the tower. |
