Patent ID: 8189811

Claim:
A signal processor comprising: a first amplifier for amplifying an input signal to produce a first signal; a mixer for producing a third signal being the sum of the first signal and a second signal; a third amplifier for amplifying the third signal to create an output signal; a first loudspeaker operatively connected to the output signal; a first processing component having, a second loudspeaker having a cone, a moving sleeve, a moving coil having first and second ends, a stationary magnet, and a ferromagnetic shaft; a second amplifier having first and second inputs; the second loudspeaker having a first grounded input and a second input operatively connected to the output signal; the cone being attached to the moving sleeve; the moving coil being wrapped around the moving sleeve; a portion of the ferromagnetic shaft being displaced within a portion of the moving sleeve; the ferromagnetic shaft being attached to the stationary magnet; the first end of the coil being operatively connected to the input signal and the first input of the second amplifier; the second end of the coil being operatively connected to the second input of the second amplifier; the second amplifier producing the second signal.
