Abstract:
The present invention relates to a speaker apparatus for reproducing a sound from an electrical signal and, more specifically, to a voice coil speaker apparatus capable of reproducing a high-fidelity sound over a wide frequency band.

Claim (Index 7):
A driving device operable to drive the speaker apparatus according to  claim 6 , the driving device comprising:\n a preamplifier operable to amplify a weak audio signal and supply the amplified audio signal to a power amplifier; and a first power amplifier operable to amplify an output of the preamplifier to drive the first voice coil; two current/voltage converters operable to convert a current of the optical displacement sensor into a voltage; a first summation circuit operable to calculate a difference between outputs of the two current/voltage converters; a gain adjustment and filter stage operable to amplify an output of the first summation circuit to an appropriate level and perform a filter function of removing noise; a second summation circuit operable to calculate a difference between an output of the gain adjustment and filter stage and the output of the preamplifier; and a second power amplifier operable to amplify an output of the second summation circuit to drive the second voice coil.
