7.9. Acoustical circuit

The acoustical circuit for the box and the port is given in Fig. 7.23. The series radiation mass and resistance on the front side of the diaphragm are, respectively, M A1 and R AR1. The mass loading on the back side of the diaphragm is M AB . The resistance due to leakage through the walls of the box, or even through a woven dust cap or gasket, is R AL . The compliance and resistance of the lined box are C AB and R AB . The mass and resistance of the air in the port that penetrates the side of the box, including the inner end correction, are M AP and R AP , respectively. Finally, the series radiation mass and resistance from the front side of the port are, respectively, M A2 and R AR2. The values of these ...
