Abstract

The electrodynamic transducers’ that are used in mobile devices are typically prone to voice coil overheating and excessive excursion of the membrane. The paper focuses on the second aspect. Nonlinear distortion is known to depend on membrane excursion amplitude. High sound pressure at low frequencies also requires the maximum vibration amplitude. But now the sound balance is at stake. Thus, we face the challenge of finding the optimal relation between the sound balance and the level of audible distortion to obtain the maximum subjective quality evaluation.
