Abstract:
Provided is a capacitive transducer drive device capable of adjusting a potential difference applied between electrodes of a cell with a simple configuration. A capacitive transducer to be driven by the drive device includes a cell including: a first electrode included in a vibrating membrane; and a second electrode formed to oppose the first electrode through intermediation of a gap. One of the first electrode and the second electrode of the cell is electrically connected to a first DC voltage applying unit, and the other of the first electrode and the second electrode of the cell is electrically connected to a second DC voltage applying unit. A voltage to be applied by the second DC voltage applying unit is set to be lower than a voltage to be applied by the first DC voltage applying unit. The voltage to be applied by the second DC voltage applying unit is variable.

Claim (Index 19):
A method of driving, by a drive device, a capacitive transducer comprising a plurality of elements, each element including a cell, the cell comprising a vibrating membrane which includes a first electrode, and a second electrode which is opposed to the first electrode through a gap,\n the drive device comprising a first DC voltage applying unit electrically connected to one of the first electrode and the second electrode, and a second DC voltage applying unit electrically connected to another of the first electrode and the second electrode, wherein the drive device is configured to transmit an acoustic wave and receive an acoustic wave, wherein the second DC voltage applying unit is configured to generate a second DC voltage, and wherein the first DC voltage applying unit is configured to generate a first DC voltage, the method comprising: setting a first DC voltage and a second DC voltage which is lower than the first DC voltage to thereby generate a bias voltage between the first electrode and the second electrode; and varying the bias voltage by varying a voltage applied by the second DC voltage applying unit without varying a voltage applied by the first DC voltage applying unit, wherein the drive device is configured to vary a DC voltage to be applied by the second DC voltage applying unit to adjust a potential difference between the first electrode and the second electrode so that the potential difference is close to characteristics of at least one of transmission efficiency or reception sensitivity among the element.
