摘要： A drive apparatus for a piezoelectric actuator prevents locking drive frequency in a state of resonance due to harmonics. There is no need to provide external components to filter, and circuitry can easily be reduced in size. The drive apparatus has a phase difference-DC conversion circuit to detect vibrating state of the vibrating body, a comparison circuit, a harmonics detection circuit to detect that the vibrating body is resonating due to harmonics and outputting a harmonics detection signal, an integration circuit to control the frequency of the drive signal supplied to the piezoelectric element of the vibrating body, a variable frequency oscillation circuit, and a drive circuit. The integration circuit, the variable frequency oscillation circuit, and the drive circuit control the frequency of the drive signal on the basis of the output of the comparison circuit when a harmonics detection signal is not outputted and continue to vary the frequency of the drive signal without controlling the frequency of the drive signal on the basis of the output of the comparison circuit when a harmonics detection signal is being outputted.

摘要： In an electronic device 1 comprising a battery 200 and a piezoelectric actuator A, a power source voltage before drive control is started is maintained by a sample holding circuit 102, a reference voltage is set by a reference voltage generating circuit 103 on the basis of the power source voltage, and a control circuit 106 stops driving when the power source voltage falls below a drive stop voltage as compared by a second comparison circuit 105, and begins driving the piezoelectric actuator A again when the power source voltage exceeds the reference voltage as compared by a first comparison circuit 104. Therefore, the device can be more easily reduced in size by using a small power source, and the driving time can be markedly reduced using an intermittent driving procedure that corresponds to the conditions of the battery voltage.

The device has a phase difference detection device (phase difference/voltage conversion circuit (51)) for detecting detection signals of longitudinal oscillation and bending oscillation from an oscillator (5) and detecting the phase difference between these two signals, frequency control devices (52 to 56) for comparing the phase difference detected by the phase difference detection device with a standard phase difference value and controlling the frequency of a drive signal sent to a piezoelectric element (17) on the basis of the results of this comparison, and an amplitude detection device (amplitude detection circuit (57)) for detecting the amplitude of the detection signal of the piezoelectric element (17). The frequency control device compares the amplitude with a standard amplitude value and controls the frequency of the drive signal on the basis of the results of this comparison.

摘要： The control circuit 131 causes drive frequency modification to be re-executed after returning the drive frequency to the prescribed drive frequency when the reduction rate of the power source voltage is higher than the standard reduction rate; specifically, when driving is being performed at a drive frequency whereby drive efficiency is poor and power consumption is high, or when the piezoelectric actuator A cannot start up for whatever reason. Therefore, since a startup failure or the like can be immediately determined based on the reduction rate of the power source voltage without a long time elapsing before the startup failure is detected, the time required for this determination can be shortened, the processing that is performed from the detection of an abnormality until optimization of the drive signal can be quickly executed, electrical power consumption can be reduced, and low-power operation can be ensured.
