摘要： An ultrasonic transducer includes: a pair of fixed electrodes including a conductive member; a vibrating film having a conductive layer; and a member which holds the pair of fixed electrodes and the vibrating film. The vibrating film is formed of nonconductive bodies and has an electrode layer formed of a conductive material. The electrode layer is applied with a DC bias voltage of a single polarity by a DC bias supply, and is also applied with an AC signal output from a signal source superimposed on the DC bias voltage. The pair of fixed electrodes have a plurality of holes of the same number at positions facing each other via the vibrating film, and an AC signal is applied between the conductive members of the pair of fixed electrodes by the signal source.

摘要： An electrostatic ultrasonic transducer includes a first electrode that has through-holes, a second electrode that has through-holes, and a vibrating membrane that is disposed such that the through-holes of the first electrode and the through-holes of the second electrode form a pair, interposed between a pair of electrodes composed of the first electrode and the second electrode, and having a conductive layer applied with a direct current bias voltage. The first electrode and the second electrode each have counter electrode portions that are formed in the through-holes to face the vibrating membrane, and a modulated wave, which is obtained by modulating a carrier wave in an ultrasonic frequency band with a signal wave in an audible frequency band, is applied between the pair of electrodes.
