Abstract: An electrical waveform generator for driving an electromechanical load includes a digital signal processor connected to a waveform generator component in turn connected to an amplifier section with a filter network, the latter being connected to sensing and conditioning circuit componentry that is in turn connected to analog-to-digital converter circuitry. A digital memory stores digitized voltage and current waveform information. The processor determines a phase difference between voltage and current waveforms, compares the determined phase difference to a phase difference command and generates a phase error or correction signal. The processor also generates an amplitude error signal for inducing the amplifier section to change its output amplitude to result in a predetermined amplitude error level for a respective one of the voltage and current waveforms.

Abstract: Disclosed is a piezoelectric actuator drive unit that includes a piezoelectric actuator drive amplifier and a piezoelectric actuator drive unit power supply. Combinations of high and low signal levels of a first control signal, which controls the supply voltage and amplifier bias voltage of the piezoelectric actuator drive amplifier, and a second control signal, which controls the driving force of the piezoelectric actuator drive amplifier, are associated with a haptic feedback function, a receiver function for generating an audio output, and a speaker function for generating music or the like. Thus, the piezoelectric actuator drive unit, which vibrates a piezoelectric actuator, is adapted to the haptic feedback function, the receiver function, and the speaker function, and can optimize its power and drive amplifier characteristics.
