Claim Text:
1. A method of optimizing the output of a parametric audio system, the steps comprising: coupling a pot core inductive device between an amplifier and an emitter, the pot core inductive device comprising a non-conductive housing comprising a first half and a second half, the first half and the second half having an outer wall, an inner wall, and a base, wherein the two halves are configured to be joined to define a cavity wherein an air gap is formed between the inner wall of the first half and the inner wall of the second half; a coil support member disposed within the housing; a coil structure disposed on the coil support member; an elastomeric material disposed in the cavity defined by the two halves of the housing configured to apply opposing pressure to the first and second halves; and an adjustment mechanism configured to permit a user to manually adjust the air gap to tune the inductive device to a determined inductive value; and manually tuning the inductance of the pot core inductive device by adjusting the pot core inductive device using the adjustment mechanism to achieve resonance of a circuit formed with the inductive device and the emitter.
