بهینه سازی اسپایدر بلندگو – کامسول

The suspension of a loudspeaker is designed to keep the membrane in place and avoid any rocking movement of the voice coil. At low frequencies, where the displacement of the membrane is significant, the stiffness of the suspension varies along the movement of the voice coil. This variation, or nonlinearity, plays a significant role in the total distortion created by the speaker. This model demonstrates the application of shape optimization to the design of the spider membrane. By changing the shape of the spider, it is possible to create a suspension system that behaves linearly all through the range of movement of the voice coil.
