Title: SPEAKER DRIVE DEVICE, SPEAKER DEVICE, AND PROGRAM
Abstract:
The speaker drive device according to one embodiment of the present invention comprises a first computation unit and a drive signal generation unit. Using a computation that uses an input signal, the first computation unit calculates information that corresponds to the position of the diaphragm of a first speaker unit, where said position corresponds to a designated first parameter. Then the first computation unit outputs a first computed signal that corresponds to the calculated information. On the basis of the first computed signal, the drive signal generation unit generates a drive signal for driving the speaker unit.
