TUNABLE INDUCTIVE DEVICE FOR PARAMETRIC AUDIO SYSTEMS AND RELATED METHODS

摘要

An apparatus and method for optimizing a parametric emitter system having a pot core inductive device coupled between an amplifier and emitter. The pot core inductive device allows for adjustments of the air gap formed between the two halves of the pot core structure to adjust its inductive value. This post-manufacture adjustability allows for corrections of differences caused by operations of other components in the audio system and to account for slight differences in the electrical circuit of different amplifier/emitter combinations. As efficiency of the system is dependent on the functional relationship between the amplifier, inductive device, and emitter, this allows for fine tuning of the signal to obtain high quality.

主权项

1. A pot core inductive device comprising:
a ferromagnetic 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 and configured to apply 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.
