Non-axisymmetric geometry for cloth loudspeaker suspensions

摘要

A suspension element used in an acoustic apparatus includes a woven fabric made of warp thread and weft thread. The warp thread extends parallel to a first major axis of the woven fabric and the weft threads extend parallel to a second major axis of the woven fabric orthogonal to the first major axis. The woven fabric further includes an inner periphery and an outer periphery. At least one of the inner and outer peripheries has a shape having one of four-fold rotational symmetry and dihedral symmetry. The shape produces a shorter distance between the inner and outer peripheries along a minor axis of the woven fabric that extends radially between the first and second major axes than a distance between the inner and outer peripheries along at least one of the first and second major axes.

1. A suspension element for an acoustic apparatus, comprising:
a woven fabric comprising warp thread and weft thread, the warp thread extending parallel to a first major axis of the woven fabric and the weft thread extending parallel to a second major axis of the woven fabric orthogonal to the first major axis, the woven fabric further comprising an inner periphery and an outer periphery, at least one of the inner and outer peripheries having a shape with one of four-fold rotational symmetry and dihedral symmetry, a distance between the inner and outer peripheries along a minor axis of the woven fabric that extends radially between the first and second major axes being shorter than a distance between the inner and outer peripheries along at least one of the first and second major axes, wherein a deformation of the woven fabric along the minor axis is substantially the same as a deformation of the woven fabric along the at least one of the first and second major axes.
