Patent ID: 7099488

Claim:
A planar line source speaker comprising: a magnet pair having a space between a first and a second member of the magnet pair; a vibratable film mounted across the space; a first line trace circuit mounted on a one side of the vibratable film; a second line trace circuit mounted on the one side of the vibratable film; wherein the second line trace circuit occupies essentially a same area of the vibratable film as the first line trace circuit without overlapping the first line trace circuit; wherein the first line trace circuit is driven with a first spectral component of an audio input signal and the second line trace circuit is driven with a second spectral component of the audio input signal; wherein the first line trace circuit is a four run trace, and the second line trace circuit is a two run trace; wherein the first line trace circuit is rectangular, and the second line trace circuit is rectangular having a size to fit inside a boundary of the first line trace circuit; and wherein the first line trace circuit is connected directly to a power amplifier and the second line trace circuit is connected to the power amplifier via a filter subsystem, the filter subsystem functioning to only pass frequencies above where the first line trace circuit begins to naturally fall off.
