Optymalizacja sprawności głośnika ze względu na masę cewki i średnicę membrany

The analysis of the voice-coil loudspeaker efficiency is developed in the paper. For a given value of the voice-coil mass there exists the optimal value of the diameter of the diaphragm, for which the efficiency achieves its maximal value. The optimal diaphragm's diameter increases with the voice-coil mass, and also optimal efficiency increases with with the voice-coil mass. The discussion of technological reality of maximization of the efficiency is done.
