Sažetak
A laboratory model of an electrodynamic loudspeaker has been realized with the membrane suspended on a hollow elastic torus positioned in the bottom of the membrane, close to the voice coil. This geometry removes the torque in the membrane coming from the maximum possible distance of the suspension on the outer rim from the voice coil. The suppressed torque results in the suppression of the Bessel vibration modes which generate stochastic deformation tilts on the membrane surface. Such tilts contribute to the intrinsic friction of the membrane, and their absence results in minor viscoelastic losses. Lateral rigidity of the torus is sufficient for operation of the loudspeaker without centric fixation.
