| 摘要 |
The invention relates to a dynamic converter with a polygonal, in particular rectangular, shape and with rounded or uncovered corners, consisting of a round or approximately round dome (4) with a coil attached to it, at least four external bulges (2, 3), and at least two intermediate bulges (5). At least two opposite bulges (2) are curved in their middle membrane plane. As a result, when static force is applied to the coil, the deformation of the bulge and intermediate bulge increases uniformly from the margin of the membrane to the coil. |
