Sažetak
The model is proposed based upon viscoelastic properties of the loudspeaker membrane, and properties considered include stress-strain hysteresis, creeping effect, initial stress effect and appearance of the temperature fluctuations on the membrane surface. The creeping displacement response dependent on the step-like excitation current has been measured on different loudspeaker configurations, and listed effects were analyzed in terms of the N-order Bennewitz-Rötger differential equation, commonly used for description of the system of vibrating viscoelastic body. The main parameter in this equation is inverse stress parameter which connects friction and restoring term in the loudspeaker vibrating system.
